Question

Recommendations of Kasturirangan Committee on WG?

Answer 1

1. Instead of the total area of Western Ghats, **only 37%** (i.e. 60,000 sq. km.) of the total area be brought under ESA under Kasturirangan report. **No sub-Classification into ESZs. Further, Kasturirangan's WG boundaries were wider than Gadgil's.** 2. **Distinguished between cultural** (58% occupied in the Western Ghats by it like human settlements, agricultural fields and plantations) **and natural landscape** (90% of it should come under ESA according to the committee). 3. A **Complete ban on mining, quarrying and sand mining in ESA** 4. **Current mining areas in the ESA should be phased out** within the next five years, or at the time of expiry of mining lease, whichever is earlier. 5. **No new thermal power projects**, but **hydro power projects allowed with restrictions.** 6. A ban on new polluting industries, called **Red Industries** 7. Building and construction projects up to 20,000 sq m was to be allowed but townships were to be banned. 8. Forest diversion could be allowed with extra safeguards.

Answer 2

1. panel used remote sensing and aerial survey methods for zonal demarcation of land in the Western Ghats. The usage of such techniques, without examining the ground reality, has caused many errors in the report. Kasturirangan report included ecologically non-sensitive areas under ESA, and left out many ecologically sensitive areas! 2. power is vested with the bureaucrats and forest officials and not with gram sabhas. 3. The use of “erroneous method” had caused inclusion of many villages under Ecologically Sensitive Areas (ESA) though there were only rubber plantations and no forest land! 4.

Under this initiative, 64 companies at 101 locations have been identified to enable collection of used cooking oil. 4. FSSAI **wants businesses using more than 100 litres of oil for frying, to maintain a stock register and ensure that UCO is handed over to only registered collecting agencies.** 5. FSSAI believes **India** has the **potential to recover 220 crore litres of used cooking oil** for the production of biodiesel by 2022 through a co-ordinated action.

Answer 5

1. **First ever**; Until now, forest biodiversity had never been assessed, but forest area was often used as a proxy indicator. 2. by **WWF** 3. The new findings were **based on the Forest Specialist Index**, developed following the **Living Planet Index methodology** — an index that tracks wildlife that lives only in forests. 4. Key findings: 1. There has been a **53% decline in the number of forest wildlife populations since 1970.** 2. Of the **455 monitored populations** of forest specialists, more than **half declined** at an annual **rate of 1.7 per cent**, on average between 1970 and 2014. 3. While the **decline was consistent** in these years among **mammals, reptiles and amphibians** (particularly from the tropical forests), it was **less among birds** (especially from temperate forests). 5. Threats: 1. **Loss of habitat** due to logging, agricultural expansion, mining, hunting, conflicts and spread of diseases accounted for **almost 60 per cent of threats.** 2. **Nearly 20 per cent** of threats were due to **overexploitation**. Of the 112 forest-dwelling primate populations, 40 were threatened by overexploitation (hunting). 3. **Climate change**, on the other hand, threatened to 43 per cent of amphibian populations, 37 per cent of reptile populations, 21 per cent of bird populations but **only 3 per cent of mammal populations**. 4. **More than 60 per cent of threatened forest specialist populations faced more than one threat.**

Answer 7

report relied on what the Bank said was the **biggest-ever database** assembled on global water quality using monitoring stations, satellite data and machine learning models. Key Findings: 1. **Deteriorating water quality is stalling economic growth**, worsening health conditions, reducing food production, and exacerbating poverty.Heavily polluted water is reducing economic growth by **up to a third in some countries.** 2. **When BOD crosses a threshold of 8 milligrams per liter**, **GDP growth** in downstream regions **drops by 0.83 percentage points**, about a third for the mean growth rate of 2.33 percent used in the study. 3. A key contributor to poor water quality is **nitrogen**, essential for agricultural production but which **leaches** into rivers and oceans where it creates hypoxia and dead zones 4. Early exposure of children to nitrates affects their growth and brain development, reducing their health and earning potential. **For every additional kilogram of nitrogen fertilizer per hectare, yields may rise up to five percent, but childhood stunting increases as much as 19 percent and future adult earnings fall by up to two percent** compared to those not affected. 5. The report estimated **enough food is lost to saline water each year to feed 170 million people**, about the population of Bangladesh.

Good practices guidance 4. Forest carbon partnership facility 5. Forest Investment Program 6. Global environment facility 7. Sustainable development goals

Answer 26

Reducing Emissions from Deforestation in Developing countries 1. first proposed by the Coalition for Rainforest Nations (CfRN), led by Costa Rica nad Papua New Guinea, at 11th CoP to UNFCCC at Montreal in 2005 to **mitigate climate change by reducing the net emission of greenhouse gases from forests (through their degradation)** by the means of **better forest management**, particularly in the **developing countries.** 2. Post this, UN-REDD program was launched in 2008 3. **It is the first Global joint UN initiative on climate change and deploys the support of three agencies: FAO, UNDP and UNEP** 4. involves a provision of **incentives, including effective technical assistance, capacity building and policy advice, to the developing countries to encourage them to "protect, better manage, and save their forest resources".** 5. At [_COP 13_](https://www.adda247.com/upsc-exam/unfccc-and-the-famous-cops/) under the Bali Action Plan, it was decided that REDD is to be included in a post-2012 framework and the details were to be decided during the [_COP 15_](https://www.adda247.com/upsc-exam/unfccc-and-the-famous-cops/) in Copenhagen

Answer 27

1. REDD+ is an extension of the REDD initiative. The "+" here includes, "sustainable management of forests, conservation, and enhancement of forest carbon stocks". REDD+ is a mechanism developed by Parties to UNFCCC. 2. It **creates a financial value for the carbon stored in forests** by offering incentives for developing countries to reduce emissions from forested lands and invest in low-carbon paths to sustainable development. Financial incentives are provided under REDD+ to developing country for the carbon stored in forests and investing in low carbon Pathways for sustainable development. Developing countries would receive results based payment for their results based action 3. At 13th CoP at Bali in 2007, the Bali Action Plan was adopted which included the decision to formulate the framework of REDD+ initiative. REDD+ was adopted at COP-16 in 2010 in Cancun. 4. All REDD+ deliberations at the international level recognize, respect, an encourage the participation of local communities in the implementation and monitoring of REDD+ initiative. 5. **UN REDD+ goes beyond simply deforestation and forest degradation and includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks**. REDD+ activities include the following: 1. Reducing emissions from deforestation 2. Reducing emissions from forest degradation 3. Conservation of forest carbon stocks 4. Sustainable management of forests 5. Enhancement of forest carbon stocks 6. COP 16 at Cancun, 2010: encouraged developing countries to develop on National Forest reference emission level or National Forest reference level. REL or RL is a benchmark for assessing performance of implementation of REDD+ in a country. The REDD+ result compare Greenhouse gas emissions during REDD+ implementation against the forest emission reference level 7. COP19 in Warsaw in 2013: the rulebook for implementation of REDD+ was formulated. Rule book was called as ‘Warsaw Framework for REDD+’.

Answer 28

The carbon stored in the forest ecosystem is called as forest carbon stock. The methodology for quantification of carbon stocks should be internationally accepted by all the countries for uniformity in global assessment. With this objective, IPCC in 2003 developed good practices guidelines as a universally accepted source book for concept definitions methods required for preparing forest carbon stock. As per GPG, there are 5 carbon pools in a forest which comprise the forest carbon stock. (described in next f/c)

Answer 35

being carried out in the himalayan states jointly by Indian Council of Forestry Research and Education (ICFRE) and International Centre for Integrated Mountain Development (ICIMOD) launched in January 2016 in Mizoram

Answer 36

1. To compensate the loss of forest area and to maintain the sustainability, the Government of India came up with a well-defined Act, known as CAMPA (Compensatory Afforestation Fund Management and Planning Authority). 2. Since 2006, the Union government has levied a charge on industries, miners and others who need to fell forests for their projects. This levy, called the “compensatory afforestation” charge, went into the Compensatory Afforestation Fund, which was to be used to plant trees in an area similar in size to the forests that have been lost due to development activity. Till 2016, the fund lay largely unused with the Centre, even as states demanded that it be handed over to them. In June, 2016, the Centre agreed, and passed the Compensatory Afforestation Fund Act. 3. The law establishes the National Compensatory Afforestation Fund under the Public Account of India, and a State Compensatory Afforestation Fund under the Public Account of each state. 4. These Funds will receive payments for: (i) compensatory afforestation, (ii) net present value of forest (NPV), and (iii) other project specific payments. 5. The National Fund will receive 10% of these funds, and the State Funds will receive the remaining 90%. 6. According to the Act’s provision, a company diverting forest land must provide alternative land to take up compensatory afforestation. 7. For afforestation, the company should pay to plant new trees in the alternative land provided to the state. 8. The funds can be used for treatment of catchment areas, assisted natural generation, forest management, wildlife protection and management, relocation of villages from protected areas, managing human-wildlife conflicts, training and awareness generation, supply of wood saving devices and allied activities 9. CAMPA has so far disbursed ₹48,606 crore to 32 States. Chhattisgarh and Odisha have had the maximum amount transferred to them, or close to ₹5,700 crore each followed by Jharkhand and Maharashtra at around ₹3,000 crore. 10. Concerns: 1. Critics, right from the time of passage of the act, have demanded that consent be sought under the Forest Rights Act from gram sabhas or village councils before any money is spent on plantations in traditional forests of Adivasis and other forest dwellers. In response to the demand, the Union government said it would ensure that the gram sabha consultations are held. The Compensatory Afforestation Fund law was subsequently passed without any clarity on how it could do with mere consultations when the Forest Rights Act demanded nothing less than the consent of gram sabhas for using forests for any other purpose. 2. Mounting evidence establishes that CA plantations destroy natural forests, harm biodiversity, undermine the rights and nutrition of local communities, and disguise rampant misuse of public funds 3. A macro-analysis of 2,548 plantations, and case studies of 63 CA plantation sites in Odisha, Jharkhand, Maharashtra and Chhattisgarh, by forest rights group Community Forest Rights—Learning and Advocacy (CFR-LA) reveals that 60% of these are monocultural commercial plantations, sometimes set up in the name of “forests". These plantations have been carried out over forest lands both claimed and titled under the FRA, and even over dense natural forests. The consent of these communities has not been sought, violating their legal rights and leading to livelihood distress. 4. The Act lacks a mechanism to monitor expenditure of funds, despite the comptroller and auditor general (CAG) report, 2013 finding massive misutilization by the forest department (FD).

Answer 41

1. first project under the National Perspective Plan for interlinking of rivers. water from the Ken river will be transferred to the Betwa river 2. Two phases: 1. Phase-I: Daudhan dam complex and Ken-Betwa link canal 2. Phase-II: Lower Orr dam, Bina complex project and Kotha barrage 3. project is expected to provide annual irrigation of 10.62 lakh hectares, drinking water supply to about 62 lakh people and also generate 103 MW of hydropower and 27 MW of solar power 4. Ken-Betwa Link Project lies in Bundelkhand, a drought-prone region, which spreads across 13 districts of UP and MP. It will be especially beneficial to districts of Panna, Tikamgarh, Chhatarpur, Sagar, Damoh, Datia, Vidisha, Shivpuri and Raisen of MP and Banda, Mahoba, Jhansi and Lalitpur of UP 5. out of the 6,017 ha of forest area coming under submergence of Daudhan dam of Ken Betwa Link Project, 4,206 ha of area lies within the core tiger habitat of Panna Tiger Reserve. 6. Union Cabinet has approved the funding and implementation of the Ken-Betwa river interlinking project at a cost of ₹44,605 crore at the 2020-21 price level. The Centre would fund ₹39,317 crore for the project, with ₹36,290 crore as a grant and ₹3,027 crore as a loan.

Answer 42

1. **The total area submerged would be 86.50 sq km, of which 57.21 sq km lies within Panna Tiger Reserve. This will account for 65.50 per cent of total submergence. SC appointed Central Empowered Committee (CEC) report** estimates that the KBLP will lead to a **loss of “10,500 hectares (105 sq km) of wildlife habitat” in the Panna Tiger Reserve including loss because of habitat fragmentation and loss of connectivity due to submergence** 2. Most areas of **Bundelkhand** that have been promised water are already being supplied by existing projects.There is a **great scope for improving the water availability** in Bundelkhand from existing resources and projects, which can be achieved faster and much cheaper. These **alternatives are not explored thoroughly.** 3. **Panna district, one of the least irrigated areas of MP**, will, on the other hand, **suffer maximum destruction**, while getting very little benefit from the project. Similarly, banda district of UP will also suffer. 4. project is based on the premise that the Ken, the smaller of the two rivers, has surplus water. But the hydrological data that is claimed to support that premise is not in public domain 5. CEC report raises the question about the **neglected water needs of the Upper Ken basin, a tribal area which this project is likely to keep permanently backward.**

Answer 43

● Ken and Betwa rivers originate in MP and are the tributaries of Yamuna. ● Ken meets with Yamuna in Banda district of UP and with Betwa in Hamirpur district of UP. ● Rajghat, Paricha and Matatila dams are over Betwa river. ● Ken River passes through Panna tiger reserve.

Answer 44

1. Antarctic region has registered its highest-ever temperature on record as mercury soared over 20 degrees Celsius in 2020 2. Larsen Ice Shelf is a long, fringing ice shelf in the northwest part of the Weddell Sea, extending along the east coast of the Antarctic Peninsula. 3. breakup of the ice shelf since the mid-1990s has been widely reported, with the collapse of Larsen A in 1995 and Larsen B in 2002 being particularly dramatic. A big chunk of Larsen C broke off in 2017 resulting in a ice-berg over 5000 sq km across and 350m high. 4. If the glaciers held in check by Larsen C spilt into the Antarctic Ocean, it would lift the global water mark by about 10 cm 5. A recent research points that Over a third of the Antarctic's ice shelf area, including 67% of ice shelf area in Antarctica peninsula, may be at risk of collapsing into the sea if global temperatures reach four degrees Celsius above pre-industrial levels

Answer 45

1. At 2020 UNGA, Xi Jinping announced that China (responsible for 25% of global GHG emissions) wud peak its GHG emissions before 2030 and aims to achieve net zero GHG emission (NZGE) by 2060. This is the first time that a major developing country has committed to reaching this goal. 2. More than 110 countries (accounting for more than half of global GDP) have committed to becoming carbon neutrality by imd century, incl emitters such as Britain, Japan, S. Korea, EU and USA. More than 65 percent of global CO2 emissions now fall under such pledges, acc to a UN estimate

Answer 46

* whether they apply to all greenhouse gases, or just CO2 * CO2 is responsible for \>75% of GW, but it is the concentration of CH4, mostly from natural gas leaks and animal husbandry, that is rising and is the biggets threat to Paris Agreement targets. * eg. N Zealand: target of net zero by 2050; but only applies to CO2, while 1/3rd of her emissions come from cattle and sheeps * lack of immediate hard targets * need for deep, near-term reductions in carbon pollution. eg. IPCC has said that manmade emissions must drop by 45% by 2030 and then 100% by 2050 to have any hope of meeting less than 1.5 deg C target * how much of a net zero commitment will be fulfilled with short-term emissions cuts, and how much will come from so-called "negative emissions technologies". * A big issue with negative emissions tech is that all such options remian deeply flawed * eg.a 2019 scheme unveiled by Swiss scientists to solve climate crisis by planting a trillion trees- quickly embraced by fossil fuel companies- was picked apart by experts as based on faulty calculations and requiring unrealistic amt of land. * simlarly atm C sequestration ideas remain in its infancy * Many national schemes leave out the aviation and shipping sectors ehich, if they were nations, would each rank in top 10 of global emitters * Experts say net zero plans should clearly separate targets for slashing greenhouse gas emissions from future carbon removal schemes

Answer 47

1. India has a tiny carbon footprint per person—about 2 metric tons compared to the U.S.’s 16 metric tons. Similarly India's C footprint is 25% that of China 2. India nowhere near CHina in development * India's per capita GDP @ PPP only 40% that of CHina * India is far less urbanized and industrialized * China’s steel demand will fall by 2050; India’s is expected to grow by a factor of roughly four. * China consumes more than four times more electricity per capita than India 3. Even as China aims to bring its emissions to net-zero by 2060, it is financing the building of coal power plants and other carbon-heavy infrastructure in many countries. 4. Principle of common but differentiated responsibilities and respective capabilities (CBDR-RC)based on historical responsibility have been the bedrock of climate actions under the UNFCCC ever since 1992 as well as of India;s call for climate justice. 5. Nicomachean ethics

Answer 48

In Nicomachean Ethics, Aristotle distinguished three forms of justice, namely distributive, commutative and corrective. 1. Distributive justice: * resources (global C space) should be distributed in terms of principles of equality, equity and merit. * developed countries continue to corner a lion’s share of the carbon space for their luxurious consumption while they goad developing countries to cut their emissions emanating from even basic needs. * Climate Action Tracker reports that climate action of major developed countries is incompatible with the goals of the Paris Agreement. 2. Commutative Justice: refers to agreements or commitments, and honouring past commitments in good faith * The targets under second commitment period of Kyoto protocol, entered into force in 2020, were unambitious, grossly inadequate and also backtracked by several developed countries as they refused to take on any targets in 2nd commitment period * The developed country delivery of finance, technology transfer, and capacity building support to developing countries is also not up to the mark. Not even close to meeting the goal of jointly mobilising at least $100 billion per year by 2020 3. Corrective justice: rightings of wrongs. * developed countries need to repay the climate debt by shouldering greater mitigation responsibilities and providing finance, technology and capacity building support to safeguard the interest of the poor and vulnerable people in developing countries. while many herald the call for net zero by 2050 as a positive signal in avoiding runaway climate breakdown, in reality it delays climate action by developed countries and is being used to evade historical responsibility and transfer burdens to developing countries.

Answer 49

In some sectors of the economy, technological progress has been so dramatic that it is possible to envisage a peak and decline in emissions by 2050. In other sectors, technologies are emerging but are still neither mature nor cost effective at scale. * Power sector emission- constitutes a significant part of INdia's emissions * dramatic cost declines in renewable energy and energy storage open up the possibility for India to peak its emissions in the power sector before 2050. * utility scale solar PV costs are projected to fall to about 2 Rs/kWh by 2030 and in the order of 1.2 Rs/kWh by 2050, acc to TERI models. costs of solar plus battery storage are projected to fall to 3.37 Rs/kWh by 2050. * Solar PV is already more competitive than coal in India; further cost declines would only cement this advantage. * By 2050, India’s total electricity demand would be about 5500 to 6000 terawatt-hours (TWh). India’s total technical potential for solar, excluding land under cropping, forests, protected area and so on, amounts to about 15,000 TWh. India’s technical potential for wind amounts to about 4000 TWh. * Aggregate emissions pathways are more uncertain, given the large emissions growth expected from sectors like industry, trucking and aviation, where technologies are less mature. Nonetheless, even here mitigation technologies are improving rapidly.

Answer 50

We often rely on metrics such as coral cover or coral mortality as a marker of reef health. But this does not always give us an accurate comparison of reef health. As we saw discussed earlier, corals have always gone through periods of coral decline and recovery. Simply having low coral cover does not necessarily indicate poor reef health if it is on the path to recovery. A reef with 20% coral cover that is restoring quickly is arguably in a better state than a reef with 60% cover that is seeing year-on-year declines. Many researchers have stressed that it’s not necessarily the absolute level of coral cover that matters for reef health, but where the reef lies between two states of equilibrium. Corals are often described in terms of a phase-shift. In one phase, a reef is resilient to pressures such as bleaching, storms, or disease; when these events occur they feel the short-term impacts but can quickly recover. This is the ‘coral-dominated state’. But there is another phase: one triggered by a non-linear response. Reefs can be pushed too far and ‘flip’ into an ‘algae-dominated’ state. This is a state where the ecosystems have fundamentally changed from one dominated by coral to one of macroalgae. This new state of equilibrium is difficult to recover from. A reef in this state is an unhealthy one. eg. Carribean Reefs. In the Caribbean we find reefs of algae, not of coral: 40% is covered by macroalgae versus only 15% of coral. It hasn’t always been this way: in the 1970s, macroalgae covered only 2% of Caribbean reefs. A 20-fold increase. Contrast that with the Great Barrier Reef where less than 5% of cover was algae, and 25% was coral. Its reefs are still very much in the ‘coral-dominated’ phase. This means they are resilient to pressures and can bounce back.

Answer 51

There are two main types of corals: shallow, warm-water corals; and cold, deep-water corals. The obvious difference between the two is that warm-water corals live close to the sea surface – usually in coastal waters – whereas cold-water reefs can extend to depths of 3,000 meters below the surface Warm and cold-water reefs therefore function in very different ways. Corals use calcium carbonate in ocean waters to build a hard exoskeleton. But the key to their success is how they get their energy. Warm-water corals contain microscopic algae called zooxanthellae in a symbiotic relationship. The algae photosynthesize for them, providing corals with most of their energy.[⁶](https://ourworldindata.org/coral-reefs#note-6) These corals wouldn’t be able to survive without them. They can only do this by living close to the surface where light is abundant. Once we reach 200 meters below the surface – which is where most cold-water corals live – there is so little light that photosynthesis is not possible. Cold-water corals don’t have these symbiotic algae, and get their energy from feeding on particles on the ocean floor instead.

Answer 52

A recent study has suggested that **coral structures may withstand climate change** owing to their impressive process of **forming rock-hard skeletons.** **The Study:** * It studied ***Stylophora pistillata,*** a common stony coral in the Indo-Pacific revealing that **coral structures consist of a biomineral** containing a highly organized organic mix of proteins that resembles human bones. * It highlighted that **several proteins are organized spatially –** a process that’s critical to forming a rock-hard coral skeleton. * The study highlighted that corals have survived global climate change over millions of years by the process called **Biomineralization.** * **Biomineralization** is the study of processes that lead to the formation of hierarchically structured organic–inorganic materials generated by living organisms, such as shells, bone and teeth.

Answer 53

* Corals are made up of genetically **identical organisms called polyps.** These polyps have **microscopic algae called zooxanthellae** living within their tissues. * The corals and algae have a **mutualistic relationship.** * The coral provides the zooxanthellae with the compounds necessary for photosynthesis. In return, the **zooxanthellae supply the coral with organic products of photosynthesis,** like carbohydrates, which are utilized by the coral polyps for the synthesis of their calcium carbonate skeletons. * In addition to providing corals with essential nutrients, zooxanthellae are responsible for the **unique and beautiful colors of corals.** * They are also called the **“rainforests of the seas”.** * There are **two types of corals:** * Hard, shallow-water corals—the kind that builds reefs. * Soft corals and deepwater corals that live in dark cold waters. * **Benefits of Coral:** * **Habitat:** Corals are home to over 1 million diverse aquatic species, including thousands of fish species. they occupy only 0.1 per cent of the global sea surfaces. But more than 25 per cent of marine biodiversity is supported by them * **Income:** * Coral reefs and related ecosystems have a global estimated value of ‘$2.7 trillion per year, or 2.2% of all global ecosystem service values’, this includes tourism and food. * loss and degradation of coral reefs can affect the livelihood of about 4.5 million people in SE Asia and the Indian Ocean. * In Bangladesh, the coral reefs of St. Martin’s Island contribute $33.6 million per year to the local economy. * It has been assessed that one square kilometre of coral reef produces 20-35 mega tonnes of fishes sufficient to feed about 600 people annually. * They are used in jewellery and as curios. The internal skeleton polished with colours is used in jewellery. Sea grasses that provide food for dugongs and dolphins are harboured by coral reefs. Coral blocks are used for buildings and road construction. The lime supplied by corals is used in cement industries. * **Coastal Protection:** Coral reefs reduce shoreline erosion by absorbing energy from the waves. They can protect coastal housing, agricultural land, and beaches. * **Medicine:** Reefs are home to species that have the potential for treatments for some of the world’s most prevalent and dangerous illnesses and diseases. * Degradation and loss of coral reefs can affect about 4.5 million people in southeast Asia and the Indian Ocean, acc to IPCC sixth assessment report * UN-IPBES Report on Species Extinction identified a **range of risks,** from the **disappearance of insects** vital for pollinating food crops, to the **destruction of coral reefs** that support fish populations that sustain coastal communities, or the **loss of medicinal plants**.

Answer 54

1. Cyclones and Tsunamis 2. Coral Diseases: also affected by coral diseases such as black band and white band due infectious microorganisms introduced by the human population that live on the coastal regions. 3. Acanthaster planci, also known as Crown-of-Thorns Star fish, eats corals during night. They may destroy the entire coral reefs if found in huge numbers.

Answer 55

1. Global Warming and CLimate Chnage 2. Ocean Acidification 3. Pollution 4. Overfishing and Destructive Fishing practices 5. Development Activities

Answer 56

* When the ocean water becomes too warm, the corals bleach as the symbiotic algae (Zooxanthallae) leave them. A brief bleaching event doesn't necessarily kill coral—but prolonged, severe bleaching can lead to disease and starvation. * Historically, global-scale coral bleaching has been associated with [El Niño](https://www.climate.gov/enso) events, which [generally raise global temperatures](https://www.climate.gov/news-features/blogs/beyond-data/how-will-el-ni%C3%B1o-affect-2015%E2%80%99s-placement-among-warmest-years-record). The first mass coral bleaching was observed during the strong El Niño in 1983, and the first truly global event coincided with the strong El Niño of 1998. The world’s tropical reefs were stressed again during a moderate-strength 2010 El Niño. * The first study to track thermal stress to corals at a global scale found that the percentage of global reefs that were impacted by bleached stress tripled over the 28-year period from 1985 to 2012. In the 1980s and ‘90s, it was rare for there to be *more* than ten events in any given year. From the millennium onwards, it was rare that there would be *less* than ten. We also see large spikes in particular years: 1983, 1987, 1998, 2010, and 2016. Most of these events were triggered by the so-called El Niño climate cycle * In the 1980s, most bleaching events were reserved for El Niño years. We see examples of this in the 1983 and 1987 spikes. Bleaching was rare in moderate or La Niña years. This was particularly pronounced when we look at *severe* bleaching events- There was almost no severe bleaching in the absence of El Niño.This is no longer the case. Over these decades we’ve seen more and more events in moderate ENSO years, and even in La Niña years, the ‘cold phase’ of the cycle. This applies to the total number of bleaching events, but also the severe ones. Coral bleaching is no longer a rare El Niño occurrence; it happens every year, regardless. * What’s new and concerning is prolonged and repeated bleaching episodes that they don’t have time to recover from. Nearly one-third of major coral reef clusters had eight or more episodes since 1980. That’s one every few years. Overall, the estimated return time of severe bleaching events has declined from once every 27 years in the 1980s to once every 5.9 years in 2016. That’s a 4.6-fold reduction. * The coral-bleaching event of 2014–2017 was unusual not just for its long duration, experts say, but also because it wasn't entirely due to El Niño. The 36-month heatwave and global bleaching event were exceptional in a variety of ways. For many reefs, this was the first time on record that they had experienced bleaching in two consecutive years. Many reefs—including those in Guam, [American Samoa](https://youtu.be/-V6DJLSqA18), and Hawaii—experienced their worst bleaching ever documented. In the[Northern Line Islands](https://media.nationalgeographic.org/assets/photos/379/628/1c8f629e-0ff3-4218-861b-46e66e21902a.jpg) in the South Pacific, upwards of 98 percent of the coral at some reefs were killed. Reefs in the northern part of Australia’s [Great Barrier Reef](https://www.climate.gov/news-features/event-tracker/fate-great-barrier-reef)that had never bleached before lost nearly 30 percent of their shallow water corals in 2016, while reefs a bit farther south lost another 22 percent in 2017. All told, more than 75 percent of Earth’s tropical reefs experienced bleaching-level heat stress between 2014 and 2017, and at nearly 30 percent of reefs, it reached mortality level.

Answer 57

ocean acidification particularly impedes the thickening process—decreasing the skeletons’ density and leaving them more vulnerable to breaking. Acc to a study, The impact will be especially strong in the Indo-Pacific region, with up to 20 percent reductions in the densities of coral skeletons by 2100 in parts of the Coral Triangle

Answer 58

1. Sewage and industrial Waste 2. Oil spills: eg. Wakashio spill off the coast of Mauritius, was near Marine Protected Area renowned for its remarkable corals including more than 1000 yr old brain coral (*Lobophyllia*), the largest brain coral in IO 3. increase in virulents in water

Answer 59

* Overfishing of certain species on or adjacent to coral reefs can affect the reef’s ecological balance and biodiversity. For example, overfishing of herbivorous fish can lead to high levels of algal growth. * Destructive fishing methods: Fishing with dynamite, cyanide, bottom trawling and Muro Ami (banging on the reef with sticks) can damage entire reefs and is unsustainable.

Answer 60

1. coastal development 2. increased sedimentation: Sedimentation is on the rise due to degradation of estuaries, salt marshes and mangrove forests. It reaches the marine ecosystem, including coral reefs, and causes suffocation to coral reefs. 3. Tourism and recreational activities: get damaged due to the fishing and tourist boats anchored on them.

Answer 61

released in 2021, first report of its kind in 13 yrs. ## Footnote 1. In the last decade, the world lost about 14 per cent of its coral reefs. 2. Threats: Ocean-acidification, warmer sea temperatures and local stressors such as overfishing, pollution, unsustainable tourism and poor coastal management. 3. Impact of global warming: Coral reefs across the world are under relentless stress from warming caused by climate change. Coral bleaching events caused by rise in elevated sea surface temperatures (SST) were responsible for coral loss. 4. Loss of hard coral cover: There has been a steady decrease in hard coral cover in the last four decades since 1978 when the world lost nine per cent of its corals. The decrease is disconcerting because live hard coral cover is an indicator of coral reef health. 5. Algal bloom: Algal bloom on coral ridges are a sign of stress on the structures. Since 2010, the amount of algae on the world's coral reefs has increased by about 20 per cent. 6. The survival of corals is likely to drop below 50 per cent if sea surface temperatures increase by one degree. 7. All of the world’s reefs will bleach by the end of the century unless the world acts together to reduce carbon emissions 8. if proper conservation and management measures are not taken, all [coral reefs of the Indo-Malayan region](https://www.downtoearth.org.in/news/climate-change/aldabra-s-coral-reefs-recovered-faster-from-bleaching-finds-new-research-73866)may disappear in the next 40 years.

Answer 62

* A number of global initiatives are being taken to address the issues, like: * [**International Coral Reef Initiative**](https://www.drishtiias.com/daily-updates/daily-news-analysis/3rd-international-year-of-reef) * Global Coral Reef Monitoring Network (GCRMN) is an operational network of ICRI (International Coral Reef Initiative)with the primary task of reporting on the condition of the world’s coral reefs. * Global Coral Reef Alliance (GCRA) * The Global Coral Reef R&D Accelerator Platform * Aichi Target 10 which concerns reducing pressures on coral reefs and other vulnerable ecosystems impacted by climate change or ocean acidification * INdia: * _Integrated Coastal and Marine Area Management launched in 1998_ aims at integrating the management of coastal and Marine areas has prepared model plans for the Gulf of Kutch. * India has also created mechanisms such as the National Coastal Zone Management Authority (NCZMA) and State Coastal Zone Management Authority for the protection of coastal and marine areas. * Ministry of Environment and Forests (MoEF), India has included _studies on coral reef under the Coastal Zone Studies (CZS)._ * **Corals are included in Schedule-I list of the Wild Life Protection Act, 1972:** Ministry of Environment and Forest vide its notification dated 11 July 2001 has included all the hard coral in the Schedule List of WLPA of 1972 * **Environment Protection Act, 1986 (EPA):** It confers exclusive jurisdiction to the Central Government to preserve and protect the marine environment and to prevent and control marine pollution. * **Coastal Regulation Zone Notification (CRZ) 1991 under the EPA**: It is the only law that explicitly outlaws coral mining in India. * **Marine Protected Areas (MPAs):** to preserve the certain areas of the nation’s waters, including some areas with coral reefs.

Answer 63

1. In the past **coral restoration** has been done as a response to a singular, destructive event like a **ship running aground**. 2. **Coral nurseries**: * Coral “farmers” nurture small, found pieces of coral on underwater structures until they can be **replanted on existing reefs**, stimulating recovery of these ecosystems. * in the low stress environment of a nursery, conservationists can **grow corals much faster, giving the reefs a fighting chance.** * more crucially, **conservationists can manage the diversity of the coral population** in nurseries. Some corals are able to withstand or recover from stresses better than others. * Nursery-grown corals can be used not only to help reefs damaged by groundings, storms or pollution but those harmed by changing ocean conditions as well. 3. scientists have discovered that “**microfragments**” sawed off these corals act a bit like wounded skin, **growing extremely quickly**—some 10 times faster than larger cuttings. Grown side by side in lab aquariums, polyps from the same colony will fuse, reducing the time needed to reach reproductive size. Raised this way, some **species that typically take a decade or more to mature have begun spawning in just a few years.** 4. corals selected are often selected for **disease** (eg. stony coral tissue loss) as well as **heat tolerance**. Effort is also dedicated to develop **heat resistant algae** and pairing them up with receptive corals 5. some scientists **scoop up slicks of eggs and sperm released by corals** that have survived bleaching and proven their heat tolerance amassing them in mesh enclosures near the ocean surface which promotes fertilization and larval formation; those offspring can then be drizzled over damaged reefs. 6. in some instances **corals already are doing the job themselves**: Scientists working on world’s largest atoll—**Kiritimati** in the central Pacific—discovered corals that were recovering from bleaching during a heat wave. They did it by taking in naturally heat-tolerant algae. 7. Meanwhile, as global temperatures trend up, some scientists have taken to prepping—**stashing hard corals in “living biobanks”** to conserve as much diversity as possible.

Answer 64

The Great Barrier Reef Marine Park, which spreads across a length of over 2,300 km and is roughly the size of Italy, is home to about 3,000 coral reefs, 600 continental islands, 1,625 type of fish, 133 varieties of shark and rays and 600 types of soft and hard corals. It is a world heritage site.

Answer 65

Singapore-registered MV X-Press Pearl, carrying chemicals and plastic, had a fire outbreak onboard followed by an explosion, following which tonnes of plastic pellet deposits were found deposited along Sri Lanka’s beaches as well as oil spill in Sri Lankan waters

Answer 66

1. oil, discharged accidentally or intentionally, that floats on the surface of water bodies as a discrete mass and is carried by the wind, currents and tides. 2. effects: 1. ecosystem destruction: Heavy oils may affect several organism functions like respiration, feeding, and thermo-regulation. 2. cna affect living beings by direct contact eg. marine mammals 3. can damage nesting grounds of sea birds 4. If the oil washes into coastal marshes, mangrove forests, or other wetlands, fibrous plants and grasses absorb oil, which can damage plants and make the area unsuitable as wildlife habitat. 5. harm tourism economy 6. power plants and other utilities that depend on drawing or discharging sea water are severely affected by oil spills. 7. harm fishing industry 3. measures: 1. containment Booms: Floating barriers, called booms are used to restrict the spread of oil and to allow for its recovery, removal, or dispersal. 2. Skimmers: devices used for physically separating spilled oil from the water’s surface. 3. Sorbents: Various sorbents (e.g., straw, volcanic ash, and shavings of polyester-derived plastic) that absorb the oil from the water are used. 4. Dispersing agents: chemicals that contain surfactants, or compounds that act to break liquid substances such as oil into small droplets. They accelerate its natural dispersion into the sea. 5. Bio agents: Nutrients, enzymes, or microorganisms such as Alcanivorax bacteria or Methylocella silvestris that increase the rate at which natural biodegradation of oil occurs are added.

Answer 67

It is a geographic area that has been permanently impaired by heavy environmental alterations or economic disinvestment, often through locally unwanted land use (LULU) causing "chemical pollution where residents live immediately adjacent to heavily polluted industries or military bases These zones most commonly happen to exist in low-income and minority communities "A sacrifice zone is when there is no choice in the sacrifice. Someone else is sacrificing people and their community or land without their permission." The concept of sacrifice zones was first discussed during the Cold War, as a likely result of nuclear fallout, and the term coined in the Soviet Union

Answer 68

* Black carbon (BC) deposits produced by human activity accelerate the pace of glacier and snow melt in the Himalayan region. * The rate of retreat of HKHK glaciers is estimated to be 0.3 metres per year in the west to 1.0 metre per year in the east. BC adds to the impact of climate change. * Deposits of BC act in two ways hastening the pace of glacier melt: by decreasing surface reflectance of sunlight and by raising air temperature. * Full implementation of current policies to mitigate BC can achieve a 23% reduction but enacting new policies and incorporating them through regional cooperation among countries can achieve enhanced benefits. * Specifically, in the Himalayas, reducing black carbon emissions from cookstoves, diesel engines, and open burning would have the greatest impact and could significantly reduce radiative forcing.

Answer 69

* BC is a short-lived pollutant that is the second-largest contributor to warming the planet behind carbon dioxide (CO2). * Unlike other greenhouse gas emissions, BC is quickly washed out and can be eliminated from the atmosphere if emissions stop. * Unlike historical carbon emissions, it is also a localised source with greater local impact. * It is formed through the incomplete combustion of fossil fuels, biofuel, and biomass, and is emitted in both anthropogenic and naturally occurring soot. * Sources of black carbon in HKHK regions: Industry [primarily brick kilns] and residential burning of solid fuel together account for 45–66% of regional anthropogenic [man-made] BC deposition, followed by on-road diesel fuels (7–18%) and open burning (less than 3% in all seasons)” in the region.

Answer 70

1. Tarballs are dark-coloured, sticky balls of oil that form when crude oil floats on the ocean surface. 2. Tarballs are formed by weathering of crude oil in marine environments. 3. They are transported from the open sea to the shores by sea currents and waves 4. Most of the times, the presence of several tarballs indicate an oil spill. However, its annual occurrence on the west coast during the monsoon has led marine biologists and experts to demand an investigation in the matter. 5. tarballs that travel towards the coast can get stuck to the fishing nets installed in the sea, making it difficult for fishermen to clean. In addition, it could affect marine life, especially filter feeders like clams and oysters.

Answer 71

* Black C is produced by incomplete high temperature combustion of fossil fuels, biofuel, and biomass, and is one of the main types of particle. Black carbon warms the Earth by absorbing sunlight and heating the atmosphere and by reducing albedo when deposited on snow and ice * Brown C is released by the combustion of organic matter. It coexists with black carbon when released in the atmosphere * Brown carbon has attracted interest as a possible cause of climate change. This class of organic carbon absorbs strongly in the ultraviolet wavelengths and less significantly going into the visible wavelengths. * Simulation models suggest that brown carbon contributes about 19% of the total atmospheric absorption by aerosols, while 72% is attributed to black carbon

Answer 72

1) Saurashtra region is interspersed with \>100 reserved vidis (grasslands) maintained by the forest department and \>400 non-reserved vidis controlled by other agencies. 2) spread over 1,810 sq km, making up 20 per cent of total grassland cover in Gujarat. 3) most of these vidis come undr 22,000-sq km Greater Gir landscape

Answer 73

1. these grasslands have degraded owing to invasion of woody and shrubby species and have turned into somewhat unproductive woodlots 2. instead of grass, growth of species like lantana, prosopis, van tulsi and cassia 3. This vegetation is unpalatable for wild ungulates and domestic animals

Answer 74

1. progressive degradation of grasslands has exacerbated some of the present problems like shortage of fodder, lack of good grazing grounds for maldharis 2. Man-animal conflict increases: increase in crop depredation by wild herbivores. As grasslands on forest fringes become unsuitable for wildlife and local livestock, the fringe further shifts towards agricultural fields and human settlements. 3. more than 1.6 crore kg of grass collected by the forest department from reserve vidis in 2018-19 will be available for distribution in the event of a drought. 4.Grasslands are important for water security too as they serve as great watersheds. 5. rassland restoration will also help in the conservation of bustards, floricans, wolves, blackbucks and many other wild species that share a similar habitat.

2.6 Bn T coeq ( doesnot include other GHGs) grew by only 1.8% in 2019 reflecting slowdown in economy (and hence electricity) as compared to \>5% in last decade. Globally, CO2 emission grew by 0.6%

Answer 87

* Globally, 50 MT per yr, weighing more than all of the commercial airlines ever made. over six kilograms for every person on the planet * Only 20% of that is formally recycled. 80% either ending up in landfill or being informally recycled – much of it by hand in developing countries, exposing workers to hazardous and carcinogenic substances such as mercury, lead and cadmium. * e-waste produced annually is worth over $62.5 billion * Global e-waste production is on track to reach 120 million tonnes per year by 2050 if current trends continue

Answer 88

1. According to the Global E-Waste Monitor 2017, India generates about 2 million tonnes (MT) of e-waste annually and ranks fifth among e-waste producing countries, after the US, China, Japan and Germany. 2. In 2016-17, India treated only 0.036 MT of its e-waste. About 95 per cent of India’s e-waste is recycled in the informal sector and in a crude manner. 3. E-waste is growing at a compound annual growth rate (CAGR) of about 30 per cent in the country. 4. Laws to manage e-waste have been in place in India since 2011, mandating that only authorised dismantlers and recyclers collect e waste. E-waste (Management) Rules, 2016 was enacted on October 1, 2017. 5. According to the CPCB, India generated more than 10 lakh tonnes of e-waste in 2019-20, an increase from 7 lakh tonnes in 2017-18. Against this, the e-waste dismantling capacity has not been increased from 8.2 lakh tonnes since 2017-18. In 2018, the Ministry of Environment had told the tribunal that 95% of e-waste in India is recycled by the informal sector and scrap dealers unscientifically dispose of it by burning or dissolving it in acids.

Answer 89

superseded e-waste (Management & Handling) Rules, 2011. 1. Manufacturer, dealer, refurbisher and Producer Responsibility Organization (PRO) have been introduced as additional stakeholders 2. applicability of the rules has been extended to components, consumables, spares and parts of EEE as well as CFL in addition to equipment as listed in Schedule I. 3. Collection mechanism based approach has been adopted to include collection centre, collection point, take back system etc for collection of e - waste by Producers under Extended Producer Responsibility (EPR). Option has been given for setting up of PRO , e - waste exchange , e - retailer, Deposit Refund Scheme as additional channel for implementation of EPR by Producers 4. Provision for Pan India EPR Authorization by CPCB has been introduced replacing the state wise EPR authorization. 5. phase wise Collection Target for e - waste, which can be either in number or Weight shall be 30% of the quantity of waste generation as indicated in EPR Plan during first two year of implementation of rules followed by 40% during third and fourth years, 50% during fifth and sixth years and 70% during seventh year onwards. 6. Deposit Refund Scheme: producer charges an additional amount as a deposit at the time of sale of the electrical and electronic equipment and returns it to the consumer along with interest when the end - of - life electrical and electronic equipment is returned. 7. manufacturer is also now responsible to collect e - waste generated during the manufacture of any electrical and electronic equipment and channelise it for recycling or disposal. dealer, if has been given the responsibility of collection on behalf of the producer, need to collect the e - waste 8. roles of the State Government has been also introduced in the Rules in order to ensure safety, health and skill development of the workers involved in the dismantling and recycling operations. 9. transportation of e - waste shall be carried out as per the manifest system whereby the transporter shall be required to carry a document (three copies) prepared by the sender, giving the details. 10. Liability for damages caused to the environment or third party due to improper management of e - waste including provision for levying financial penalty for violation of provisions of the Rules has also been introduced. 11. ULBs has been assign the duty to collect and channelized the orphan products to authorized dismantler or recycler.

Answer 90

objective: channelizing the E-waste generated in the country towards authorized dismantlers and recyclers in order to formalize the e-waste recycling sector. 1. e-waste collection targets under EPR have been revised and will be applicable from 1 October 2017. The phase-wise collection targets for e-waste in weight shall be 10% of the quantity of waste generation as indicated in the EPR Plan during 2017-18, with a 10% increase every year until 2023 2. Separate e-waste collection targets have been drafted for new producers, i.e. those producers whose number of years of sales operation is less than the average lives of their products. The average lives of the products will be as per the guidelines issued by CPCB from time to time. 3. Producer Responsibility Organizations (PROs) shall apply to the Central Pollution Control board (CPCB) for registration to undertake activities prescribed in the Rules. 4. Under the Reduction of Hazardous Substances (RoHS) provisions, cost for sampling and testing shall be borne by the government for conducting the RoHS test. If the product does not comply with RoHS provisions, then the cost of the test will be borne by the Producers.

Answer 92

1. a power plant fuel leak in Russian Arctic region-Krasnoyarsk caused 20,000 tonnes of diesel oil to escape into a local river, **Ambarnaya. The river also houses Pyasino Lake and then later flows into Pyasina river that ultimately flows into Kara sea.** 2. The power plant is located near the Siberian Peninsula’s Norilsk city, around 3000 km northeast of Moscow. 3. The thermoelectric power plant is built on permafrost, which has weakened over the years owing to climate change. This caused the pillars that supported the plant’s fuel tank to sink., leading to a loss of containment 4. Environmentalists have said the river would be difficult to clean, given its shallow waters and remote location, as well as the magnitude of the spill. This is the second-largest known oil leak in modern Russia’s history in terms of volume. 5. Damages to the Arctic waterways could be at least 6 billion rubles (over $76 million). This excludes atmospheric damage due to greenhouse gases and soil pollution. The installed buoys will only help collect a small part of the pollution and nearly all the diesel fuel will remain in the environment.

Answer 94

1. Anthropocene extinction 2. Mass extinction refers to a substantial increase in the degree of extinction or when the Earth loses more than three-quarters of its species in a geologically short period of time. So far, during the entire history of the Earth, there have been five mass extinctions 3. Researchers have described it as the “most serious environmental problem” since the loss of species will be permanent. 4. loss of species has been occurring since human ancestors developed agriculture over 11,000 years ago. 5. Changes occured and occuring: * Earth was once home to two million known species. According to the study, however, since 1500, as many as 7.5%-13% of these species may have been lost. That numbers anywhere from 150,000 to 260,000 different species. * More than 400 vertebrate species went extinct in the last century, extinctions that would have taken over 10,000 years in the normal course of evolution. * In a sample of 177 species of large mammals, most lost more than 80 per cent of their geographic range in the last 100 years, and 32 per cent of over 27,000 vertebrate species have declining populations. * Several species of mammals that were relatively safe one or two decades ago are now endangered, including cheetahs, lions and giraffes. There are as few as 20,000 lions left in the wild, less than 7,000 cheetahs, 500 to 1,000 giant pandas, and about 250 Sumatran rhinoceros. * As many as half of the number of animals that once shared our planet are no longer here, a loss described as “a massive erosion of the greatest biological diversity in the history of Earth”. 6. Vulnerable regions: Tropical regions have seen the highest number of declining species. In South and Southeast Asia, large-bodied species of mammals have lost more than four-fifths of their historical ranges.

Answer 96

NEED: * move comes as the outbreak of coronavirus (COVID-19) has raised global concern about illegal wildlife trade and zoonotic diseases. * While import of live exotic animals is covered under Customs Act in India, wildlife experts have long been asking for stringent laws and guidelines to document and regulate numbers of exotic species being kept as pets by individuals and breeders in India. * Many citizens have kept CITES enlisted exotic animal species in their possession. * there is no unified information system available of such stock of species at the State or Central level. * often these species are illegally trafficked into the country to avoid lengthy documentation and scrutiny.

Answer 97

1. According to the advisory, the phrase “exotic live species” includes “animals named under the Appendices I, II and III of the CITES of Wild Fauna and Flora” and “does not include species from the Schedules of the Wildlife (Protection) Act 1972” 2. Environment Ministry will collect stock information from the holders of such species through voluntary disclosure in next six months. 3. The registration will be done for the stock of animals, new progeny, as well as for import and exchange. 4. The declarer would not be required to produce any documentation in relation to the exotic live species if the same has been declared within six months of the date of issue of the advisory. 5. For any declaration made after six months, the declarer shall be required to comply with the documentation requirement under the extant laws and regulations. 6. Further, a person trying to import a live exotic animal will have to submit an application for grant of a licence to the Directorate General of Foreign Trade (DGFT), under the provisions of the advisory. 7. The importer will also have to attach a No Objection Certificate (NOC) of the chief wildlife warden of the state concerned along with the application.

Answer 98

xperts said the advisory did not provide answers to all problems. 1. Matters such as spread of invasive species as well as zoonotic diseases had not been taken care of in the advisory. 2. Limiting the scope of the latest advisory to only those species covered under CITES drastically limits the scope of the advisory itself. 3. There is also a growing domestic trade in exotic species of wildlife that is unfortunately not listed under the various appendices of CITES (such as sugar gliders, corn snakes). 4. There is no mention of the welfare standards of such captive facilities that could lead to ‘legal’ backyard breeding of wildlife with poor to no welfare concern of the wild animals involved.

Answer 99

Exotic live species are animal or plant species moved from their original range to a new one most often by people. Some of the most sought after exotic species in India are Ball python, Scarlet Macaw, sea turtles, sugar glider (Petaurus breviceps), marmoset and grey African parrots.

Answer 100

The Chief Wildlife Warden (CWLW) is the statutory authority, under the Wildlife Protection Act, who heads the Wildlife Wing of the State Forest department and exercises complete administrative control over Protected Areas (PAs) within a state. Every PA is typically classified as a Wildlife Division and is headed by a Deputy Conservator of Forests (DCF).

Answer 101

* recently conducted by the Gujarat government * conducted once every five years. This year it was delayed due to lockdowns. * The first Lion Census was conducted by the Nawab of Junagadh in 1936; since 1965, the Forest Department has been regularly conducting the Lion Census eve Key figures this year: 1. 28% rise in population of Lions: Total estimated Lions in Gir region is 674. It was 523 in 2015. 2. 36% Expanse in distribution: Today, Asiatic lions are present in Protected Areas and agro-pastoral landscapes of Saurashtra covering nine districts, over an expanse of about 30,000 sq. km. It was 22,000 sq. km in 2015. 3. Factors responsible for steady rise in population: * community participation * emphasis on technology * wildlife healthcare * proper habitat management * steps to minimise human-lion conflict * ry five years.

Answer 102

1. Poonam Avlokan (developed in 2014) is a monthly in-house exercise carried out every full moon. 2. About 1400 Field staff and officers spend 24 hours assessing the number of lions and their locations in their respective jurisdictions. 3. These staff kept moving in their respective territories and made their estimates based on inputs provided by lion trackers and on chance sightings

Answer 103

* India uses this method to estimate the number of lions. * In this method, census enumerators remain stationed at water points in a given block and estimate abundance of lions in that block, based on direct sighting of lions who need to drink water at least once in 24 hours during the summer. * There are inherent issues with this method. So, newer methods should be adopted- such as camera trapping and identifying lions based on permanent marks on their body, and statistical estimates based on the animals’ predatory patterns and numbers of their prey base.

Answer 104

1. Every year, the state Forest Department invites NGOs, experts and wildlife enthusiasts to join the Census for transparency and augmenting manpower. 2. But this time, it was not advisable to send so many people inside the forest as the Bronx Zoo in New York had reported a case of transmission of novel coronavirus from a human to a tigress. 3. So, this year, the count was estimated not from a Census, but from a population “observation” exercise called Poonam Avlokan. 4. Unlike previous census, which had nearly 2000 participants, this census had around 1400 staff and a few experts.

Answer 105

Few experts are doubtful about the estimated numbers. They say it could be an overestimation. It is because: * 12 lions were killed in a flash flood in Amreli just a month after the 2015 census. * More than two dozen lions died in an outbreak of **canine distemper virus (CDV)** and **babesiosis** in 2018. * A **babesiosis outbreak** was reported this summer too, and around two dozen lions are reported killed.

Answer 106

* Presently, Asiatic lions are confined only to Gujarat. A single epidemic could wipe the entire population and the species might become extinct. * The Kuno-Palpur Wildlife Sanctuary in Madhya Pradesh was identified to be the most suitable for reintroducing the species, according to a Supreme Court-appointed technical expert committee, but there has been no progress on the proposal. * The SC in April 2013 had ordered the translocation of some lions from Gujarat to Madhya Pradesh

Answer 107

1. launched by MoEFCC fr 2018-21 2. The Asiatic Lion. endemic to Gir landscape of Gujarat is one of the 21 critically endangered species identified by the Ministry for taking up recovery programmes. 3. The project envisages scientific management with the involvement of communities in coordination with multi-sectoral agencies for disease control and veterinary care for overall conservation of Asiatic lion. 4. This project has “Species Conservation over a large landscape” approach. Large landscape conservation generally involves many forest divisions, government agencies, and conservation organizations. 5. ICT) is proposed in the conservation, protection and development efforts of the Greater Gir Region like GPS Based Tracking, Automated Sensor Grid like Magnetic Sensors, Movement Sensors, and Infra-red heat sensors, Night vision capability enhancement, GIS-based real-time monitoring, analysis and report generation.

Answer 108

* Asiatic lions are slightly smaller than African lions. * Asiatic Males have only moderate mane growth at the top of the head so that their ears are always visible. * darker manes on asiatic lions * african lions: live in bigger grps * The most striking morphological character, which is always seen in Asiatic lions, and rarely in African lions, is a longitudinal fold of skin running along its belly. * IUCN status: Endangered Asiatic vs Vulnerable african lions

by CPCB into red, orange and green categories based on the quantity of waste water generated. * Red: railway stations generating waste water equal to or more than 100 Kilo Litres per Day. * Orange: those greater than 10 KLD but less than 100 KLD. * Green: less than 10 KLD waste water generation.

Answer 111

* The majestic, endangered bird is massive, making it slow to maneuver in flight. It has poor frontal vision, and an unfortunate habit of scanning the earth while flying across the flat grasslands of India’s western borders. That combination too often sets it on a fatal collision course with power lines. * The wide-open region that’s home to the rare bird has long been an ideal location for wind and solar projects. * In an effort to save the great Indian bustard from flying into power lines, a Supreme Court order is asking for transmission lines in a large swathe of the region to go underground. The companies say the directive could cost an estimated $4 billion in extra expenses, and jeopardize nearly 20 gigawatts of awarded solar and wind projects * Besides the transmission wires, a rapid conversion of grassland for farming or industrial projects and a slow birth rate -- bustards lay one egg every year or two -- have also led to their depleting numbers.

Answer 112

1. It is a concept in environmental justice movement, developed in USA in 1970s and 80s 2. In USA, environmental racism criticizes inequalities between urban and exurban areas after white flight. Internationally, environmental racism can refer to the effects of the global waste trade, like the negative health impact of the export of electronic waste to China from developed countries. 3. four factors which lead to environmental racism: lack of affordable land, lack of political power, lack of mobility, and poverty. 4. Manifestation of climate racism within a nation in five ways: racial discrimination in defining environmental policies, discriminatory enforcement of regulations and laws, deliberate targeting of minority communities as hazardous waste dumping sites, official sanctioning of dangerous pollutants in minority communities, and the exclusion of people of color from environmental leadership positions. 5. Processes such as suburbanization, gentrification, and decentralization lead to patterns of environmental racism: * suburbanization: non-minorities leaving industrial zones for safer, cleaner, and less expensive suburban locales. minority communities are left in the inner cities and in close proximity to polluted industrial zones. * Indigenous communities are losing their way of life with CC. eg. Loss of red sockeye salmon in Snake river in Idaho, not only disrupts the economy of Nez Perce (an indigenous community) but also also disrupts their symbiotic relationship with nature 6. Internationally, climate racism can also include 1. while island nations bear little to none responsibility in causing CC, they are the forefront of threat from rising sea levels 2. while developed countries have reached their development levels causing uncontrolled emissions, developing countries like INdia are expected to grow with added constraint of emission minimization

T ## Footnote This is to help States construct infrastructure and enable them to receive ‘Blue Flag’ certification. The Blue Flag certification requires beaches to create certain infrastructure — portable toilet blocks, grey water treatment plants, a solar power plant, seating facilities, CCTV surveillance and the like. However, India’s CRZ laws don’t allow the construction of such infrastructure on beaches and islands.

Answer 121

* **13** pilot beaches have been identified for the certification. * These include * **Ghoghala** Beach (**Diu**), * **Shivrajpur** beach (**Gujarat**), * **Bhogave** (Maharashtra), * **Padubidri** and **Kasarkod** (Karnagaka), * **Kappad** beach (Kerala) etc. * **Chandrabhaga beach of Odisha’s Konark coast** was the **first to complete the tag certification process** **will be the first in Asia to get the Blue Flag certification.**

1. worst in decades * In total, **more than 7.3 million hectares** (17.9 million acres) have been burned across Australia’s six states — an **area larger than the countries of Belgium and Denmark combined.** * **NSW hardest hit**, with more than 4.9 million hectares burned * Blazes have torn through bushland, wooded areas, and **national parks like the Blue Mountains.** * Number of total **animals** affected could be **as high as one billion** nationwide. Almost **a third of koalas in NSW** may have been killed in the fires, and a third of their habitat has been destroyed. * air pollution in surrounding regions marked by red skies. 2. **Each year there is a fire season** during the Australian summer, with hot, dry weather making it easy for blazes to start and spread. For years, the **fires have been starting earlier in the season and spreading with greater intensity.** 1. Natural causes are to blame most of the time, like lightning strikes in drought-affected forests.eg. Dry lightning was responsible for starting a number of fires in Victoria’s East Gippsland region. 2. Humans can also be to blame 3. It was further **exacerbated by Australia's one of the worst droughts** in decades, a **heatwave** in Dec that broke the record for highest nationwide average temperature and **strong winds** that spread fire and smoke more rapidly. 2019 was the hottest on record for Australia with the temperature reaching 1.52 ° Celsius above the long term average 4. The Fire later created their own weather. The smoke from the fire created pyrocumulonimbus cloud. These clouds created thunderstorms and lightning that caused more fire. 5. Apart from a few loss of life and thousands of homes destroyed, unique ecosystems like blue mountains world heritage area in New South Wales and the Gondwana world heritage rainforest in Queensland got burnt 6. Climate feedback loop: according to NASA, the bushfire pumped around 350 million tons of of CO2 into the atmosphere. This is roughly two third of Australia annual emissions budget in 2018-19. It may take a century or more for forests to absorb the Co2 released so far during the Fire

Answer 123

1. It allows “forests” to be traded as a commodity. 2. It allows the Forest Department to outsource one of its responsibilities of reforesting to non-government agencies. * The scheme allows agencies — they could be private companies, village forest communities — to identify land and begin growing plantations. * After three years, they would be eligible to be considered as compensatory forest land if they met the Forest Department’s criteria. * An industry needing forest land could then approach the agency and pay it for parcels of such forested land, and this would then be transferred to the Forest Department and be recorded as forest land. 3. This is not the first time that such a scheme has been mooted. In 2015, a ‘Green Credit Scheme’ for degraded forest land with public-private participation was recommended, but it was not approved by the Union Environment Minister 4. Present scenario: * In the current system, industry needs to make good the loss of forest by finding appropriate non-forest land — equal to that which would be razed. * It also must pay the State Forest Department the current economic equivalent — called Net Present Value — of the forest land. * It’s then the Forest Department’s responsibility to grow appropriate vegetation that, over time, would grow into forests. 5. Need: * Industries have often complained that they find it hard to acquire appropriate non-forest land, which has to be contiguous to existing forest. * Nearly ₹50,000 crore had been collected by the Centre over decades, but the funds were lying unspent because States were not spending the money on regrowing forests. After SC's intervention, about ₹47,000 crore had been disbursed to States until August, but it has barely led to any rejuvenation of forests.

1. It is a chemical used by foam manufacturers. 2. It is used mainly as a blowing agent in the production of rigid polyurethane (PU) foams. 3. It is one of the most potent ozone depleting chemical after Chlorofluorocarbons (CFCs). 1. **Acc to MoEFCC, INDIA has successfully achieved the complete phase out of hydrochlorofluorocarbon (HCFC)-141 b** 2. Nearly, 50% of the consumption of ozone depleting chemicals in the country was attributable to HCFC-141 b in the foam sector. 3. India has now emerged as one among the few countries globally and a pioneer in some cases in the use of technologies, which are non-Ozone Depleting and have a low Global Warming Potential (GWP). 4. The complete phase out of HCFC 141 b from the country in foam sector is among the first at this scale in Article 5 parties (developing countries) under the Montreal Protocol. 5. IN dec 2019, India had banned issuance of import licence for HCFC-141b under Ozone Depleting Substances (Regulation and Control) Amendment Rules, 2019 issued under EPA 1986

Answer 127

1. aka **Mineral accretion technology**, It is the substance formed by **electro accumulation of minerals dissolved in seawater on steel structures that are lowered onto the sea bed** and are **connected to a power source**, in this case solar panels that float on the surface. 2. The technology works by passing a small amount of electrical current through electrodes in the water. When a positively charged anode and negatively charged cathode are placed on the sea floor, with an electric current flowing between them, **calcium ions combine with carbonate ions** and adhere to the structure (cathode). 3. This results in calcium carbonate formation. Coral larvae adhere to the CaCO3 and grow quickly. 4. Fragments of broken **corals** are tied to the biorock structure, where they are able to **grow at least four to six times faster than their actual growth as they need not spend their energy in building their own calcium carbonate skeletons.** 5. **Zoological Survey of India (ZSI)**, with help from Gujarat’s forest department, is **attempting for the first time** a process **to restore coral reefs using biorock in gulf of Kachh**

recently commissioned at the Mancheswar Carriage Repair Workshop in **Odisha**. The plant, a patented technology called **Polycrack**, is first-of-its-kind in the Indian Railways and fourth in the country.

Answer 130

The cheetah is the only large carnivore that has been extirpated, mainly by over-hunting in India in historical times. The country’s last spotted feline died in Chhattisgarh in 1947. Later, the cheetah — which is the fastest land animal — was declared extinct in India in 1952. NTCA has decided to reintroduce **African Cheetah, frm Namibia, into Nauradehi WLS and Palpur Kuno WLS in MP** **Government is preparing to translocate the first batch of eight from South Africa and Namibia to Kuno National Park in Madhya Pradesh soon after the situation linked to the current third wave of Covid-19 becomes normal, and total 50 in various parks over a period of five years** Nauradehi WLS found most suitable as its forests are not very dense to restrict the fast movement of the spotted cat. Besides, the prey base for cheetahs is also in abundance at the sanctuary. **NAURADEHI WLS** Kopra River, Bamner River, Vyarma River and Bearma River, which are tributaries of the Ken River, are the major rivers of this protected area. Some smaller streams flow southerly to the Narmada river in the south of the sanctuary Palopur Kuno WLS-\> Kuno NP (covered in NPs) Wildlife Institute of India at Dehradun had prepared a ₹260-crore cheetah re-introduction project seven years ago. **_Cheetah reintroduction programme in India:_** Wildlife Institute of India at Dehradun had prepared a ₹260-crore cheetah re-introduction project seven years ago. This could be the world’s first inter-continental cheetah translocation project

Answer 131

Introduction not a reintroduction. We are not “reintroducing” a species that went extinct recently in India, instead we are “introducing” an alien predator in a habitat where they never ever existed. South African cheetahs definitely did not exist in India ever. They are a different sub species than the Asiatic cheetah that is still found in small numbers in Iran. These genetic difference maybe minor but is large enough to be declared as separate sub species. “At this stage, in our view, the decision taken by MoEF for introduction of African cheetahs first to Kuno and then the Asiatic lion is arbitrary and illegal and clear violation of the statutory requirements provided under the Wildlife Protection Act…The order of MoEF to introduce African cheetahs into Kuno cannot stand in the eye of Law and the same is quashed,” the Supreme Court stated in its order in 2013. The same court took a complete U turn in 2020 though the law and the plan didn’t change at all. A 2019 paper by Divyabhanu Sinh &[@RazaKazmi17](https://twitter.com/RazaKazmi17)has by far the most detailed compilation of records of cheetah for the last 250 years. A total of 199 records from British India (including Baluchistan - where Asiatic cheetahs did exist) in 250 years. More than half of these records are of captive cheetahs and not wild. However according to the distribution map of cheetahs in India that is at the core of this introduction - the highest number of records of cheetahs are from Tamil Nadu, south Karnataka - Kerala border, Jharkhand and Deccan. there are hardly any records from north west India, including Kuno, which is actually not a good habitat for cheetahs. Kuno has a nearly identical terrain as Ranthambhore - hilly, rocky, thorny dry forest. Not a cheetah habitat by any definition. A major objective of the project is to restore grasslands and open forest systems. In Kuno forests are being cleared to create grasslands. These grasslands would need to be “maintained” by clearing the bush cover regularly. This is not restoring, this is destroying forests. The bar for success of the project is kept really low. The project would be deemed a failure if the all the cheetahs fail to survive or reproduce in 5 years. Cheetahs need huge areas of grassy plains. How huge? 100 to 300 to 500 square kilometres or more for one cheetah or one coalition of males. There is not a single grassland in India large enough to accommodate even one cheetah. Not a single one.

Answer 132

1. IUCN: * Cheetahs are classified as 'Vulnerable' yb IUCN * African Cheetahs are Vulnerable; * Asiatic cheetahs are **Critically Endangered** 2. CITES: both in Appendix I 3. Found where: * Around 6500-7500 African cheetahs present in the wild * only 40-5 ASiatic cheetahs are found, that too only in Iran * **Asiatic cheetahs was officially declared extinct from India in 1952** 4. Physical comparison: african bigger in size; Asiatic has more fur and more cat-like appearance

Answer 133

The new regulations, called IMO 2020, have been regarded as the biggest shake up for the oil and shipping industries in decades. It affects more than 50,000 merchant ships worldwide. Key features of the rules: 1. The IMO has banned ships from using fuels with a sulphur content above 0.5 per cent, compared with 3.5 per cent previously. 2. The new limits are monitored and enforced by national authorities of countries that are members of the International Convention for the Prevention of Pollution from Ships (MARPOL) Annex VI. 3. Under the new policy, only ships fitted with sulphur-cleaning devices, known as scrubbers, are allowed to continue burning high-sulphur fuel. 4. Alternatively, they can opt for cleaner fuels, such as marine gasoil (MGO) and very low-sulfur fuel oil (VLSFO). Issues: * There are complaints against VLSFO as testing companies have claimed that high sediment formation due to the fuel’s use could damage vessel engines. * recently environmental activists called for a ban on the use of new low sulphur marine fuel in the Arctic region, citing a research which shows that blends of very low-sulfur fuel oil (VLSFO) contribute to highly polluting black carbon emissions in the environment.

Answer 134

According to an IEA analysis, 90 per cent of new electricity generation capacity around the world now comes from renewables. India is among the world’s top five countries in terms of renewable power capacity. It further aims to increase renewable capacity to 450GW by 2030. If achieved, low-carbon energy sources could account for more than 60 per cent of India’s total power capacity in 2030, well above what it originally committed to under the Paris Agreement. But not everyone benefits immediately or equally- new jobs would need to be found over time for the coal miners affected by the changes, as well as for people who work in the fossil fuel power plants that will close down.

Answer 135

1. According to the Council on Energy, Environment and Water (CEEW), the deployment of 450 GW of renewables would employ more than half a million workers. 2. workers in fossil fuel driven energy sector will need retraining for work in other sectors 3. Credible severance packages and insurance cushions 4. Policymakers must earmark special “transition funds” to help coal-dependent regions, some of which are among India’s poorest, to remodel their economies and develop new industries. 5. Energy subsidies must be rationalised and directed towards those who need them most. sustain the gains of the Saubhagya and Ujjwala schemes. Fiscal resources freed up through subsidy reform should then be invested in clean energy solutions, especially in underdeveloped regions and marginalised communities. 6. A just transition should focus on how clean energy can support rural livelihoods and increase communities’ resilience in the face of CC or threats like the present pandemic 7. share the benefits of clean energy technologies with micro-entrepreneurs and small businesses. In rural India, clean energy innovations for farms and businesses offer a market opportunity worth more than $50 billion. The energy transition in rural India can be driven by dedicated policies to promote renewables, incentivise investment in decentralised low-carbon power sources like rooftop solar, and train and build the capacity of clean energy entrepreneurs. 8. Gender parity in the remodelled ennergy sector- According to a 2019 study by CEEW and the IEA, women account for nearly 32 per cent of the renewables workforce globally but only around 11 per cent of the rooftop solar workforce in India. As a priority, renewable energy companies must promote policies to ensure gender parity in their workforce. These could include investments in suitable facilities for women at project sites, designing guidelines for flexible working arrangements, and creating programmes to prepare more women for leadership roles. 9. Incorporating energy efficiency and green construction methods into affordable housing projects could ensure millions of homes enjoy thermal comfort, and help make energy efficiency a core part of building designs. Many local jobs could also be promoted by the Make in India eg. manufacturing energy-efficient appliances, battery technologies and components for RE systems 10. engaging the youth: It is the emerging generation of innovators and entrepreneurs that will provide the technical and social solutions of the future.

Answer 136

Set up in 1988 by the WMO and the UNEP, the IPCC does not itself engage in scientific research. Instead, it asks scientists from around the world to go through all the relevant scientific literature related to climate change and draw up the logical conclusions. The IPCC reports are created by three working groups of scientists. * WG-I: deals with the scientific basis for climate change. * WG-II: looks at the likely impacts, vulnerabilities and adaptation issues * WG-III: deals with actions that can be taken to combat climate change. The assessment reports are the most widely-accepted scientific opinion about climate change. They form the basis for government policies to tackle climate change, and also provide the scientific foundation for the international climate change negotiations. So far, five assessment reports have been produced, the first one being released in 1990. The fifth assessment report had come out in 2014 in the run up to the climate change conference in Paris. The first part of 6th Assessment Report was released in Aug 2021.

Answer 137

in 1990 findings: * Emissions resulting from human activities are substantially increasing the atmospheric concentrations of the greenhouse gases. * Global temperatures have risen by 0.3 to 0.6 degree Celsius in last 100 years. In business-as-usual scenario, temperatures likely to increase by 2 degree Celsius compared to pre-industrial levels by 2025, and 4 degree Celsius by 2100 * Sea-level likely to rise by 65 cm by 2100 This report formed the basis for negotiation of the UNFCCC in 1992

Answer 138

in 1995 * Revises projected rise in global temperatures to 3 degree Celsius above pre-industrial levels by 2100, sea-level rise to 50 cm, in light of more evidence. * Global rise in temperature by 0.3 to 0.6 degree Celsius since late 19th century, “unlikely to be entirely natural in origin”. This report was the scientific underpinning for Kyoto Protocol in 1997.

Answer 139

in 2001 * Revises projected rise in global temperatures to 1.4 to 5.8 degree Celsius by 2100 compared to 1990. Projected rate of warming unprecedented in last 10,000 years. * Rainfall will increase on an average. The report also predicts that by 2100, the sea level is likely to rise by as much as 80 cm from 1990 levels. Glaciers to retreat during the 21st century. * Frequency, intensity and duration of extreme weather events to increase. * Presents new and stronger evidence to suggest that global warming is mostly attributable to human activities.

Answer 140

in 2007 * GHG emissions increased by 70 per cent between 1970 and 2004. * Atmospheric concentrations of CO2 in 2005 (379 ppm) the maximum in 650,000 years. * In worst case scenario, global temperatures could rise 4.5 degree Celsius by 2100 from pre-industrial levels. Sea-levels could be 60 cm higher than 1990 levels. The report won the 2007 Nobel Peace Prize for IPCC and was the scientific input for the 2009 Copenhagen climate meeting.

Answer 141

in 2014 * More than half the temperature rise since 1950 attributable to human activities. * Atmospheric concentrations of carbon dioxide, methane and nitrous oxide “unprecedented” in the last 800,000 years. * Rise in global temperatures by 2100 could be as high as 4.8 degree Celsius from pre-industrial times * More frequent and longer heat waves “virtually certain”. * “Large fraction of species” face extinction. Food security would be undermined. This report formed the scientific basis for negotiations of the Paris Agreement in 2015.

Answer 142

background: The Haryana government had ordered to break 10,000 jhuggis in Khori Gaon without providing any rehabilitation plan. The order was given as the jhuggis are located in a forest area and the residents don’t have any ownership over them. SC has recently backed the govt's decision issues: 1. unprecedented stress on the residents, who are already facing immense uncertainties during the pandemic. 2. Ishita Chatterjee’s scholarly work on Khori Gaon shows that this basti should be seen as restorer of quarry land, because the residents turned these areas that were mined till the SC’s mining ban in 2002, into liveable habitats by using individual and community labour. This is no mean feat when governments around the world struggle to reuse mined areas after the earth has been polluted and exhausted of all its productivity. 3. the order doesn’t extend to big high-rise buildings located in the same forest area. This includes The Taj Vivanta Hotel, the Sarovar Portico Hotel etc. 4. undermines the right to shelter under Article 21 of the Indian Constitution as no prudent plan for rehabilitation is given. * In the Ahmedabad Municipal Corporation case, the Supreme Court held that it would be the duty of the state to provide the right to shelter for the poor and needy. 5. it violates India’s international obligation. The country has ratified the UN International Covenant on Economic, Social, and Cultural Rights which guarantees a right to housing for all irrespective of income.

Answer 143

first announced in Budget 2021-22 policy is estimated to cover 51 lakh Light Motor Vehicles (LMVs) that are above 20 years of age and another 34 lakh LMVs above 15 years of age. provisions: 1. Fitness test 1. Old vehicles will have to pass a fitness test before re-registration;will be tested at Automated Fitness Centres acc to international standards. Emission test, braking system, safety components will be tested. Vehicles failing the tests will be scrapped 2. government commercial vehicles more than 15 years old and private vehicles which are over 20 years old will be scrapped. But only if they fail te automated fitness test. 2. Road tax rebate: SGs can offer a road-tax rebate of up to 25% for personal vehicles and up to 15% for commercial vehicles to provide incentive to owners of old vehicles to scrap 3. vehicle discount: Vehicle manufacturers will also give a discount of 5% to people who will produce the 'Scrapping Certificate' and registration fees will be waived off on the purchase of a new vehicle. 4. disincentive: increased re-registration fees would be applicable for vehicles 15 years or older from the initial date registration. 5. Not all provisions applicable to Delhi NCR * *The policy does not classify vehicles based on their fuel type. This is different from rules applicable in Delhi NCR. The latter rules state that diesel vehicles over 10 years old and petrol vehicles more than 15 years old “shall not ply” on the roads of Delhi-NCR and are “liable to be impounded and invite necessary penal action under Motor Vehicles Act, 1988” due to the region’s hazardous levels of air pollution.*

Answer 144

The vehicle scrappage policy is the first-of-its-kind, institutional mechanism to de-register any vehicle. Till date, there are nearly 33 crore vehicles registered in India. So, essentially a vehicle registered in the 1950s may still be “registered” 1. The vehicle scrappage policy envisages creating a mechanism to retire “end of life vehicles”. These are vehicles that are no longer fit to be driven on roads and have high negative externalities such as pollution emission, lower fuel efficiency and safety risk for commuters. it is estimated that nearly 13-17 crore vehicles would reach this stage in the next 10 years. 2. Pollution: 1. Vehicular pollution in India is responsible for nearly 30 per cent of carbon emissions making India the third-largest emitter in the world. 2. older vehicles pollute the environment 10 to 12 times more 3. 17 lakh medium and heavy commercial vehicles are more than 15 years old. 4. As per the Vahan database of the Ministry of Road Transport and Highways, there are more than one crore vehicles that do not have a valid fitness or registration certificate. 3. It will lead to creation for more scrap yards in the country and effective recovery of waste from old vehicles. government’s vehicle scrapping policy aspires to augment investments towards setting up automated fitness testing centres which will be state of the art 4. employment: In the new fitness centers, 35 thousand people will get employment and an investment of Rs 10,000 crores will be pumped in. 5. improved revenue: will boost sales of heavy and medium commercial vehicles. Especially in reinvigorating the economy post pandemic. During the global economic recession in 2008-09, Cash for Clunkers and the Car Allowance Rebate System (CARS) were similar initiatives by the American federal government. will snowball the annual turnover of the industry by 30 per cent in the coming years. 6. reduction in prices: Prices of auto components would fall substantially with the recycling of metal and plastic parts. As scrapped materials will get cheaper the production cost of the vehicle manufacturers will also reduce. It will further boost circular economy 7. ALigned with international best practices. CARS initiatve in USA in 2008-09; EU with ~9MT of ELVs every yr, puts the responsibility of treatment of ELVs onto the producers; Many developed countries have adopted circular economy principles to ensure optimal utilisation of ELVs as a resource for future automobile manufacturing. 8. Mayapuri in Delhi, Kurla in Mumbai, Pudhupettai in Chennai, Mallick Bazaar in Kolkata, Jawahar Auto Nagar in Vijayawada, Auto Nagar in Guntur — are examples of huge vehicle scrapping ecosystems in urban areas across India. 9. At present, there exists an unorganised informal market for vehicle scrapping in India. This unorganised sector value chain is highly unstructured, labour-intensive and non-environment friendly. Moreover, since the informal sector uses crude methods for dismantling and recycling, the full value of high-strength steel alloys and recovery of precious metals is not realised.

Answer 145

1. Limited incentive and poor cost economics for trucks. 2. Lack of addressable volumes for other segments. 3. The potential benefit from scrapping a 15-year-old, entry-level small car will be ₹70,000, whereas its resale value is around ₹95,000. That makes scrapping unattractive.

Answer 146

GEP is the total value of final ecosystem goods and services supplied to human well-being in a region annually, and can be measured in terms of biophysical value and monetary value. Ecosystems that can be measured include natural ecosystems such as forests, grassland, wetland, desert, freshwater and ocean, and artificial systems that are based on natural processes like farmland, pastures, aquaculture farms and urban green land, etc. Uttarakhand is set to become the first state in the country to assign monetary value to four of its critical natural resources-air, water, forest and soil and thus incorporate GEP into calculation of SGDP

Answer 147

GEP is the total value of final ecosystem services supplied to human well-being in a region annually. It indicates the overall health of the environment as GEP measures prime indicators such as forest cover, soil erosion, air quality and dissolved oxygen in river water. Unlike Green GDP which is obtained after deducting the damage to the environment from the total production of the state, GEP will assess the improvement in the environment components in a year. Further it will tell how much work the state has done in reducing the loss of the ecosystem in environmental protection and resource use.

Answer 148

* Economic growth alone cannot represent true economic development. The Traditional System of National Accounts (SNA) like GDP/GNP neither accounts for the value of natural resources and ecosystem services nor the value of environmental/resource degradation taking place during the developmental process. * Accounting GEP into GDP will give a true measure of the nation's growth towards sustainable development. * Framing adequate policies: GEP helps in understanding the impact of anthropological pressure on our ecosystem and natural resources. This will enable us to make policies that will balance ecology and economy.

Answer 149

1. Knowledge gap: There is lack of data and an existent challenge to assign a monetary value to ecosystem services. Assigning monetary value to ecosystem services is possible only to a limited extent. For example, the pipal tree in India is revered as a holy tree and religious ceremonies are conducted under its shade. Here economic valuation of the tree cannot encompass the complexity and the ecological, socio-cultural and institutional heterogeneity of a particular area. 2. Policy gap: There is lack of recognition of ecosystem services in economic decision-making, development planning and resource allocation. Value of ecosystem services is either ignored or inadequately understood. 3. Institutional failure: Insufficient ‘Compensation for ecosystem services’ (CES) provided by the government to stakeholders. CES involves recognising and compensating people who manage the land that contribute to the longterm security of ecosystem functions. It is a new financial resource for funding conservation measures to ensure a vital ecosystem. Prominent CES mechanism is ‘Payments for Ecosystem Services’ (PES)

Answer 150

1. System of Environmental and Economic Accounts (SEEA): guidebook developed by the United Nations to provide standards for incorporating natural capital and environmental quality into national accounting systems. 2. China (since 2004) has been undertaking studies to estimate the cost of various types of environmental damage which offsets its economic growth. China’s investment in pollution control and renewable energy has been growing rapidly since then. 3. The Happy Planet Index (HPI) created by the British New Economics Foundation (NEF) measures national welfare in the context of environmental sustainability. 4. Bhutan’s Gross National Happiness (GNH) has environmental preservation as one of gour policy obj 5. Sweden (since 2003) has brought in various environmental indicators (like air emissions , waste etc.) as part of the government policy of achieving sustainable development

Answer 151

An ethanol blend is defined as a blended motor fuel containing ethyl alcohol that is at least 99% pure, derived from agricultural products, and blended exclusively with gasoline. Since it is plant based, it is considered to be a renewable fuel

Answer 152

1. Ethanol Blending Programme introduced in 2003 by Min of PNG 2. Currently, the bioethanol blending in petrol stands at 5%. 3. Government has been notifying administered price of ethanol since 2014. Government has allowed ethanol production/ procurement from sugarcane-based raw materials viz. C & B heavy molasses, sugarcane juice / sugar / sugar syrup, surplus rice with Food Corporation of India (FCI) and Maize 4. The Oil Marketing Companies are to procure ethanol from domestic sources and blends ethanol at its terminals 5. Remunerative prices of ethanol produced from different feedstock has been fixed 6. Department of Food and Public Distribution (DFPD) is the nodal department for promotion of fuel grade ethanol producing distilleries in the country 7. National Biofuel POlicy was introduced in 2018 in line with EBP ad INterest subvention scheme was introduced for enhancement of ethanol production capacity. It envisaged an indicative target of 20% blending of ethanol in petrol and 5% blending of biodiesel in diesel by 2030. Sugar mills and distilleries are also free to set up ethanol plants after obtaining statutory clearances, with the government notifying an interest subvention scheme to assist companies. 8. The government has set targets of 10% bioethanol blending of petrol by 2022 and to raise it to 20% by 2030 under the Ethanol Blended Programme (EBP). Recently, the central government has advanced the target of 20% ethanol blending in petrol (also called as E20), by five years to 2025, from 2030 9. In 2020, CCEA has approved Pradhan Mantri JI-VAN (Jaiv Indhan- Vatavaran Anukool fasal awashesh Nivaran) Yojana to create an ecosystem for setting up commercial projects and boost to Research and Development in 2G Ethanol sector.

Answer 153

T Since ethanol is produced from plants that harness the power of the sun, ethanol is also considered as renewable fuel.

Answer 154

1. reduce pollution: blended fuel mixture is oxygenated so it burns more completely and reduces polluting emissions. It also offers higher octane number in comparison to petrol. * Using bioethanol in older engines can help reduce the amount of carbon monoxide produced by the vehicle thus improving air quality. 2. Carbon Neutral: Combustion of ethanol made from biomass (such as corn and sugarcane) is considered atmospheric carbon neutral because as the biomass grows, it absorbs CO2, which may offset the CO2 produced when the ethanol is burned 3. economic benefits: It will help lower India’s energy import dependency and thus, lowering the crude oil import bill. India’s net import cost stands at $551 billion in 2020-21. It is estimated that the E20 program can save the country $4 billion i.e Rs 30,000 crore per annum 4. farmers' income: About 10 billion litres of ethanol will be required each year to meet the 20% ethanolblended fuel standard by 2025. Hence it is benefitting the sugarcane farmers. Last year, oil companies procured ethanol worth about Rs 21,000 crore. 5. helps in fulfilling India's NDC under Paris agreeement

Answer 155

Although the country has made steady progress in raising the share of ethanol in auto-fuels, having increased it to 8.1% in Ethanol Supply Year (ESY) 2020-21 (December-November) from 5% a year earlier, several issues will need to be addressed if the target of 20% blending by 2025 is to be achieved. 1. Vehicle Modifications: The use of E20 will require new engine specifications and changes to the fuel lines, as well as some plastic and rubber parts due to the fuel’s corrosive nature. The engines will need to be recalibrated to achieve the required power, efficiency and emission level balance due to the lower energy density of the fuel 2. The cost of E20 compatible vehicles is expected to be higher 3. Water Footprint: Sugarcane is a water intensive crop and continues to be the most lucrative food crop for ethanol even though it has highest water consumption per acre. One litre of ethanol from sugar requires about 2860 litres of water. 4. availability of sugarcane: In order to achieve a 20% blend rate, almost one-tenth of the existing net sown area will have to be diverted for sugarcane production. 5. Ethanol production facilities: India has an ethanol production capacity of 684 crore litre. For the targeted 20% blending of ethanol in petrol by 2030, the country will need a 1,000-crore litre capacity 6. The prices of ethanol produced in India are higher in comparison to global players, since the cost of raw materials like sugarcane and food grains are fixed by the government to support the farming community 7. Restrictions on inter-state movement of ethanol due to nonimplementation of the amended provisions of Industries (Development & Regulation) Act, 1951 by all the States. As on date only 14 states have implemented the amended provisions. 8. availability: about 50% of total pump nozzles in India are supplying only E0. Also, blending has not been taken up in North-East states due to non-availability of feedstock or industries

Answer 156

* Under PM-JIVAN (Jaiv Indhan- Vatavaran Anukool fasal awashesh Nivaran) Yojana, 12 commercial plants and 10 demonstration plants of Second Generation (2G) Bio-Refineries are envisaged to be set up in areas having sufficient availability of biomass so that ethanol is available for blending throughout the country. * 2G plants utilise surplus biomass and agricultural waste to produce bioethanol. * CCEA approved ₹8,460 crore Modified scheme for extending interest subvention for those setting up standalone ethanol distilleries using grain, molasses, dual feed, sugar beet, sweet sorghum and cereals as a feedstock. The focus is on increasing India’s ethanol production capacity. * Prime Minister has launched a Pilot Project of E 100 dispensing stations at three locations in Pune.

Answer 157

* An FFV is a modified version of vehicles that could run both on gasoline and doped petrol with different levels of ethanol blends. * These are currently being used successfully in Brazil, giving people the option to switch fuel (gasoline and ethanol). * Government plans to issue guidelines for 'flex-fuel' vehicles (FFV) by October 2021. The government is also working on an incentive scheme to promote manufacture and use of flex engines in vehicles. * For auto companies, introduction of FFVs will pose another challenge that they are already facing with the fast adoption of electric vehicles. If standards on FFVs are made mandatory, it would require additional investment in production lines and technology transfers to change the character of the vehicles

Answer 158

benefits ● FFVs are aimed at reducing the use of polluting fossil fuels and cutting down harmful emissions. ● Alternative fuel ethanol is Rs 60-62 per litre while petrol costs more than Rs 100 per litre in many parts of the country, so by using ethanol, Indians will save Rs 30-35 per litre. ● For India, FFVs will present a different advantage as they will allow vehicles to use different blends of ethanol mixed petrol available in different parts of the country. ● Also, these vehicles are a logical extension of the Ethanol Blended Petrol (EBP) programme launched by the Union Ministry of Petroleum and Natural Gas in January 2003. ● Since India has surplus produce of corn, sugar and wheat, the mandatory blending of ethanol programme will help farmers in realising higher incomes. ● For the overall Indian economy, higher usage of ethanol as an automobile fuel will help save import costs as the country meets more than 80 per cent of its crude oil requirements through imports Concerns: 1. Customer acceptance will be a major challenge since the cost of ownership and running cost are going to be very high compared with 100 per cent petrol vehicles. 2. Running cost (due to lower fuel efficiency) will be higher by more than 30 per cent when run with 100 per cent ethanol (E100). 3. Flex Fuel Engines cost more as ethanol has very different chemical properties than petrol. Ethanol has very low (40 per cent) Calorific value as compared to Gasoline, very High Latent heat of vaporization causing cooling of charge/combustion etc. 4. Ethanol also acts as a solvent and could wipe out the protective oil film inside the engine thereby could cause wear and tear.

Answer 159

It is an approach of watershed management It seeks to detain, divert, store and use available rainwater. This allows better management of water flowing from the ridge to the valley and ensures conservation of rainwater This approach also helps in strengthening the durability of soil and water conservation structures downstream. Case Study: Ridge to valley approach addressed the problem of water scarcity in Kondamanayunipalem village of Anantapur district in Andhra Pradesh.

Answer 160

Biofuels — ethanol and methanol — have failed to take off in India because of 1. inadequate feedstock availability 2. less than anticipated commercial production 3. numerous problems with the planting and care of oilseed plantations. * millions of saplings of Jatropha curcas were planted around food crops in central India in the 2000s, but their ownership and upkeep ran into issues between rural communities and state governments. As a result, their seed output was well below projections. 4. The quantities of crop needed to power all of India’s road transport with biofuels are just too large for the option to be practical 5. biofuels in their pure form, or when blended with gasoline do burn cleaner. Unlike EVs, though, they cannot offer zero tailpipe emissions.

Answer 161

The first commercial plant to convert 1,75,000 tons of refuse-derived fuel into 45 million litres of aviation turbine fuel is being commissioned outside Reno, Nevada A three times larger plant is coming up at Gary, Indiana, and six more sites have been identified in other medium-sized cities.

Answer 162

Israel is a laboratory for the development of practical solutions to the climate crisis. * Israel has learned * to establish agriculture in the desert and arid areas, * to recycle 90 per cent of its wastewater, and * to desalinate drinking water. * It has developed solutions for energy storage, energy efficiency, and renewable energy * Israel’s climate innovation also provides solutions in the fields of compressed-air energy storage, energy generation from sea waves, the use of advanced computing tools for energy management; * it has cultivated a groundbreaking industry of animal protein substitutes * Products such as poultry, milk, eggs and more are being produced in laboratories using methods that emit almost no greenhouse gases, and which allow huge swathes of agricultural land currently being used for livestock purposes to be freed up for ecological restoration and reforestation. * knows how to preserve forests in conditions of drought and aridity.

Answer 163

* what: is being prepared by BMC. It will look at climate resilience with mitigation and adaptation strategies by focusing on six areas — * sustainable waste management, * urban greening and biodiversity, * urban flooding and water resource management, * building energy efficiency, * air quality, and * sustainable mobility. * need: city faces two major climate challenges — * the rise in temperature: * city has seen a constant rise in temperature after 2007 * number of extreme caution days is increasing (*caution days are those where the temperature is between 26-32 degree Celsius*) * extreme rain events which will lead to flooding: a substantial increase in intense rainfall and storm events in the last five years. From 2017 to 2020, there is a steady increase in the number of extremely heavy rainfall events. * a recent IPCC report warned that at least 12 Indian coastal cities including Mumbai will face sea rise of 0.1 metres to 0.3 metres in next three decades due to climate change. * in February 2020, a report from McKinsey India stated that by 2050, Mumbai will see a 25 per cent increase in the intensity of flash floods and a 0.5 metre rise in sea level, which will affect two to three million people living within 1-km from the coastline. * Mumbai’s commitment to C40 Cities climate leadership group. Mumbai joined C40 Cities group in December 2020. * Mumbai’s greenhouse gas emission was 34.3 million tonnes in 2019. As per the data, 95 per cent of Mumbai’s electricity is coal-based and needs to be shifted to renewable energy to bring down emissions. * To minimise the impact of climate change, the MCAP will focus on reduction of greenhouse gas emission by sectors, and consumption patterns, for the near term (2030), medium term (2040) and long-term (2050). With the help of the vulnerability assessment, increasing community resilience capacities in vulnerable neighborhoods, building climate resilient infrastructure and nurturing robust natural systems will be done that can help the city better adapt to increasing climate risks

Answer 164

* will cross 1.5 °C over pre-industrial levels in the next 20 years (By 2040) and 2°C by the middle of the century without sharp reduction of emissions. * last decade was hotter than any period of time in the past 1,25,000 years. Global surface temperature was 1.09°C higher in the decade between 2011-2020 than between 1850-1900. * This is the first time that the IPCC has said that the 1.5°C warming was inevitable even in the best case scenario. * global net-zero by 2050 was the minimum required to keep the temperature rise to 1.5 degree Celsius.

Answer 165

* They are the highest in at least two million years. Humans have emitted 2,400 billion tonnes of CO2 since the late 1800s. * Most of this can be attributed to human activities, particularly the burning of fossil fuels. * The effect of human activities has warmed the climate at a rate unprecedented in 2,000 years. * The world has already depleted 86% of it’s available carbon budget.

Answer 166

* sea level rise: * Sea-level rise has tripled compared with 1901-1971. * The Arctic Sea ice is the lowest it has been in 1,000 years. * Coastal areas will see continued sea-level rise throughout the 21st century, resulting in coastal erosion and more frequent and severe flooding in low-lying areas. * About 50% of the sea level rise is due to thermal expansion * Precipitation and Drought * Every additional 0.5 °C of warming will increase hot extremes, extreme precipitation and drought. * Additional warming will also weaken the Earth’s carbon sinks present in plants, soils, and the ocean. * Heat Extremes: Heat extremes have increased while cold extremes have decreased, and these trends will continue over the coming decades over Asia. * receding snowlines and melting glaciers * freezing level of mountains are likely to change and snowlines will retreat over the coming decades. * Retreating snowlines and melting glaciers is a cause for alarm as this can cause a change in the water cycle, the precipitation patterns, increased floods as well as an increased scarcity of water in the future in the states across the Himalayas. * The level of temperature rise in the mountains and glacial melt is unprecedented in 2,000 years. The retreat of glaciers is now attributed to anthropogenic factors and human influence.

Answer 167

1. Heatwaves: Heatwaves and humid heat stress will be more intense and frequent during the 21st century over South Asia. 2. Monsoon: Changes in monsoon precipitation are also expected, with both annual and summer monsoon precipitation projected to increase. * The South West Monsoon has declined over the past few decades because of the increase of aerosols, but once this reduces, we will experience heavy monsoon rainfall. 3. Sea Temperature: * The Indian Ocean, which includes the Arabian Sea and Bay of Bengal, has warmed faster than the global average. * The sea surface temperature over Indian ocean is likely to increase by 1 to 2 °C when there is 1.5°C to 2°C global warming. * In the Indian Ocean, the sea temperature is heating at a higher rate than other areas, and therefore may influence other regions.

Answer 168

1. Amazon 2. Boreal Forest shift 3. Permafrost 4. Greenland Ice Sheet 5. West Antarctic Ice Sheet 6. Atlantic Meridional Overturning Circulation (AMOC) 7. Indian Monsoon 8. West African Monsoon 9. Coral Reefs

Answer 169

* Tipping point of this rainforest is defined as the moment deforestation becomes so high that the Amazon will not be able to sustain itself and trigger the dieback of the entire rainforest. * Amazon may be close to this point— though tropical rainforests are known for their power to sequester CO₂ and thereby act as a carbon sink, today the Amazon is a “net” source of emissions due to large-scale forest loss. Its net emission is 1 gigatonne CO 2 ( G tCO 2 ) a year, caused mainly by fires set to clear land for beef and soy production, and made worse by hotter temperatures and droughts. * The worrying trend is that the Amazon is emitting carbon even without fires. The trees produce much of the region’s rain; so, fewer trees mean more severe droughts and heatwaves; and then more tree deaths and fires—a vicious cycle * A study in journal *O**ne Earth* , claims that the Amazon shows significantly more vulnerability to climate and land-use stressors than forests in Africa and Asia.

Answer 170

* Boreal forests refer to those located near the Arctic tundra, in a biome known as “taiga”.Trees here are species of conifers, black spruce, fir and pine. * Spanning 0.6 billion ha across Europe, Russia, Canada and the US, Boreal forests are a key part of the land sink that sucks up one-third of the total CO2 emissions. A large part of this carbon is stored in the soils of boreal forests. * As temperatures rise, environments that support these forests are retreating further north. * As the global and local climates become warmer and drier, wildfires are damaging large sections of the forests and converting them into grasslands. * In 2015, nasa funded a major field experiment called the Arctic-Boreal Vulnerability Experiment (above) to understand the vulnerability of the Arctic and boreal ecosystems to CC. It found that a layer of organic matter in the soil protected the oldest carbon known as “legacy carbon”. In older forests, this was protected from fire due to the thickness of the organic layer, but in younger, drier forests the layer was shallower, and fires could reach the legacy carbon and release it into the atmosphere * A study published in Nature in April 2021 found that North American boreal forests in Alaska and Canada have already been a carbon source rather than a sink over a 31-year period between 1986 and 2016. * In July 2021, Russia’s Yakutia region experienced the driest summer in 150 years

Answer 171

IPCC SROCC 2019 defined permafrost as ground that remains at or below 0^oC for at least two consecutive years. Its thickness ranges from 1 m to more than a kilometre. It is composed of soil, rock, sediment and ice, and covers a quarter of the northern hemisphere, parts of the southern hemisphere and ocean floors—about 20 per cent of the world’s land surface. The permafrost holds a vast amount of carbon—almost twice as much that is found in the Earth’s atmosphere. This carbon is under threat of release as the Arctic, which has thrice the amount of permafrost than Antarctica, is warming twice as fast as the planet. Global average temperature has increased by 1.2^oC since 1900, but for the Arctic this is close to 2^oC Thawing would lead to decomposition of the organic material held in the ground. This process releases not only CO2 but methane as well. An August 2021 study in pnas found a surge in methane emissions, from thawing rock formations in Siberia’s permafrost during a heatwave in 2020.

Answer 172

* During a heat wave from July 28 to July 31, Danish scientists observed an ice melt of 8 billion tonnes per day, which is twice the average rate of melting for summer. The melted water was enough to cover the state of Florida in the US. * The temperatures in many regions of Greenland have been 10^oC above normal. On July 29, the Nerlerit Inaat airport in eastern Greenland scorched at 23.4^oC—its highest. * The Greenland ice sheet is expected to be one of the first thresholds we would cross but the process will be slow. The critical threshold for breaching the tipping point of the Greenland ice sheet is somewhere between 0.8^oC and 3.2^oC of warming above the preindustrial levels, as per a paper published in Nature in 2012. A 2019 study in Nature says the Greenland ice sheet might cross its tipping point at around 1.5oC of warming above the pre-industrial levels which could happen as soon as 2030 * If the entire ice sheet melts it may increase sea levels by 7 m over thou-sands of years. * Just in the last three decades, the ice sheet has lost over 4,000 billion tonnes of ice permanently. Fifty per cent of this loss has been due to increased meltwater which is a direct consequence of increasing temperatures in the region

Answer 173

* Temperatures in Antarctica have been rising at unprecedented levels, causing many ice shelves to break off * Just in February 2021 the continent recorded its highest-ever temperature (18.3^oC) in Hope Bay at the northernmost tip of Antarctica. This is due to a weather phenomenon known as Fohn conditions created by a high pressure systems which cause downward winds and raise the surface temperature of the land significantly * As per the World Meteorological Organization, temperature in Antarctica is already 3^oC above pre-industrial levels, making it one of the fastest warming regions in the world. * This region is so vulnerable that it could breach its point of no return any time. In some parts the impacts might be already irreversible. In West Antarctica’s Amundsen Sea Embayment, the line where ice, ocean and bedrock meet is retreating irreversibly, which indicates that it might have crossed its tipping point. Another vulnerable region in West Antarctica is the Bellinghausen sea sector where rate of sea ice loss is close to 160 giagtonnes a year. * The rate of ice loss for Antarctica as a whole has increased from 40 gigatonnes a year in 1979 to more than 250 gigatonnes in 2017 * The cumulative rise in sea levels due to this ice loss has been pegged at up to 16 mm since 1979, of which almost half came from the West Antarctic ice sheet * regions called ‘marine ice sheets’—are areas where the ice sheet is resting on land well below sea level, with a significant bedrock slope downward as you move inland from the coast. With this geometry, initial retreat at the ice edges in the form of faster ice flow and thinning, results in further retreat of the line inward toward thicker ice (a taller column of ice). The thicker ice then deforms quicker, causing the ice to thin and flow faster. The shape, once changed, leads to ‘rapid’ loss of the ice sheet, within a few centuries in most models

Answer 174

* AMOC is a large scale temperature and salinity driven current in the Atlantic ocean, often known as the Gulf Stream. Warm salty surface waters from tropics are transported northwards, which then cool, and the increased density causes downwelling (overturning) in the North Atlantic, which is then transported back south at the bottom of the ocean * Increased freshwater added to the North Atlantic, from increased precipitation or melting Greenland ice sheet, could disrupt the downwelling (reduced salinity and hence reduced density) and lead to a collapse of amoc * A collapsed amoc would cause widespread cooling across the northern hemisphere and less precipitation in the northern hemisphere's mid latitudes * s. In the last few decades amoc has already slowed down by 15 per cent. It is at its slowest in last 1,600 years, according to a paper published in Feb 2021 in *Nature Geoscience* * palaeoclimate data from the last 100,000 years suggests that amoc has two states: a fast and strong one that it has been in for the last few thousand years, and a slow and weak one that it now seems to be turning towards. Their analysis also shows that amoc could switch between these two states in a matter of a few decades

Answer 175

* one of the least studied among the climate tipping points. * One of the most drastic changes is visible in the northeast region of the country where 19 of the last 21 years have witnessed a below normal monsoon * In 2021 the monsoon winds stalled for a record 24 days from June 19 to July 13 because of anomalous westerly winds coming from north Africa and Saudi Arabia which were in turn linked to the heat waves all around the northern hemisphere at the end June 2021. The heat waves were caused by the disruptions in the jet stream which is linked to the rapidly warming Arctic region * Another change is the pre-monsoon weather events like cyclones and land-based convective storms that have disrupted the onset and progress of the monsoon over the sub continent. “Intense pre-monsoon rainfall usually destroys a well-organised monsoon system and delays monsoon advance. s in 2021 temperatures in northern Pakistan and northern and central India were 4oC lower than average, leading to slowing monsoon advance and alternating premature rainfall and dry spells * Research also indicates that the entire monsoon circulation is moving slightly towards the north. This would mean major changes in the distribution of rainfall. * Further LP systems that form in the BoB and cause a major portion of monsoon rainfall, especially over central India, have been decreasing and may get reduced by half with rise in temperatures. On the other hand, land-based low pressure systems will increase but by only 10 per cent. This shows the balance of temperatures between land and ocean during monsoon season has changed significantly. * Locating a precise point where the tipping of the monsoon would occur is rather difficult at this point, but massive changes are already visible at 1.2oC of global warming and future warming shows that monsoon rainfall may decrease by up to 45 per cent by end of century

Answer 176

it has interconnections with many other climate tipping points, especially amoc. The collapse of amoc might change the wind and rain patterns of the West African monsoon The West African monsoon is powered by the temperature difference between the cooler tropical Atlantic Ocean and the warmer African continent. The balance in temperatures on land and in the ocean which drives rainfall during these seasons may get disturbed by the slowing down of amoc as the heat transfer from northern hemisphere to the southern hemisphere becomes inefficient and warms up the tropical Atlantic Ocean. A disruption to the West African monsoon would cause further droughts in the Sahel region The disruption in the monsoon winds has also been linked to the greening of the Sahara which is being caused by more rain towards the north of the continent. Changes in West African monsoon which could lead to disruptions in the lives of 300 million, mostly agriculturalists of West and Central Africa

Answer 177

Scientists believe that many of the reef systems around the world have already breached their points of no return and saving them would be next to impossible. Greatest threats: climate change, overfishing, introduction of invasive species, changes in land use and pollution Despite covering only 0.1 per cent of the ocean floor around 100 countries, coral reefs host 37 per cent of all marine fish species along with other marine animals. Further they provide livelihood to 500 million people and provide ecosystem services which would be difficult to account for. For instance, they provide protection to coastal areas from waves generated during storms. 2016-2017 bleaching event in the Great Barrier Reef, which is the largest coral reef system in the world off the northeastern coast of Australia, killed 50 per cent of the corals. It happened after record breaking temperatures in 2016, which was the hottest year ever recorded, along with a strong El Niño event

Answer 178

1. **FAO** in its 2020 forest resource assessment report notes that **each hectare of forests provides 163 tonnes of carbon stock**, which remains stored in living biomass, in dead wood, litter and in soil, but with variations based on geography and type of forests. 2. FAO also says that The **global forest carbon stock decreased between 1990 and 2020, from 668 Gt to 662 Gt**, due to an overall decrease in forest area. In Europe, North America and East Asia, forest cover increased in the two decades, but Africa, South America and southern Asia saw decrease in forest cover 3. Research published in Nature Climate Change in January 2021 says that the **world’s forests sequestered twice as much CO 2 as they emitted between 2001 and 2019** 4. They **"removed" 15.6 gigatonnes (Gt) of CO 2 a year, while emitting 8.1 GtCO2 on average**. Thus they soaked in 7.6 GtCO 2 each year, which is a little less than the emissions of China in 2020 (roughly 10 GtCO 2) and more than the annual emissions of the US. 5. In two decades, forests **removed 15.2 GtCO 2—some 30 per cent of the CO2 emitted during the period** 6. ipcc’s Special Report on Climate Change and Land 2019 (**srccl) also estimates that between 2007 and 2016, land use accounted for 13 per cent of CO 2 emissions**, but provided a net sink of 11.2 GtCO₂ per year, or **29 per cent of the total CO₂ emissions** in the period. 7. latest assessment by **ipcc notes that additional warming will weaken these sinks**. Additionaly, with deforestation, drought and land-use changes, this removal is decreasing. 8. **Brazil, the Democratic Republic of the Congo and Indonesia, where average annual net loss of forest area has been highest between 2010 and 2020**, are home to largest **tropical rainforests** that are superior in their ability to remove CO2— they **remove 55 per cent of gross CO2 than boreal and temperate forests combined** 9. In fact, **tropical and sub-tropical forests have the highest emissions (78 per cent of gross emissions) due to deforestation.** This means, major global net sinks now lie in temperate forests (47 per cent) and boreal forests (21 per cent) due to lower emissions compared to tropics (31 per cent). 10. research has shown that **better management in all major natural terrestrial habitats, including grasslands, wetlands and farmlands, could help provide up to 37 per cent of the CO2 mitigation needed** through 2030 for more than 66 per cent chance of keeping warming to less than 2^o C. These include **mangroves, whose carbon storing rates are 45 times greater** than forests and other ecosystems; **peatlands that hold 25 per cent of the world’s carbon despite covering 2-3 per cent of land area**; and **grasslands that are more resilient** to droughts and wildfires than forests. 11. Former nasa scientist James Hansen estimated in 2017 that soil and biosphere can store a maximum additional limit of 100 GtC (367 GtCO2 ) via improved agricultural and forestry practices. 12. If business-as-usual emissions continue, the **strength of the land sink could halve by 2040**. Data shows the **intact tropical forest carbon sink has saturated**, while European forests may be heading towards carbon sink saturation as well

Answer 179

* role of forests as a pathway to mitigate emissions in fact dates back to 1992, when it was recognised in UNFCCC * Kyoto Protocol in 1997 endorsed the notion that governments should employ policies to enhance the land's carbon sink capacities in their territories * At the 2009 UN CoP, a position paper by the IUCN advocated to “make full use of nature-based solutions in the post-2012 climate change regime”. * Subsequently in 2011, iucn launched the Bonn Challenge “to restore 150 million hectares of the world's degraded and deforested lands by 2020 and 350 million hectares by 2030” where countries and organisations made pledges in “million hectares” of forested land to be restored. * In March 2019, the UN General Assembly declared 2021-2030 as the UN Decade on Ecosystem Restoration * In January 2020, major corporations signed on to the “1 trillion trees” initiative at the World Economic Forum in Davos * In May 2021, the G7 countries pledged to conserve or protect at least 30 per cent of global land and 30 per cent of the ocean by 2030 to halt and reverse biodiversity loss and address CC * in April 2021, at US President Joe Biden’s Leader Summit, leaf (Lowering Emissions by Accelerating Forest Finance) Coalition was announced as a public-private effort led by the US, UK and Norway and supported by corporations like Unilever, Amazon, Nestle and Airbnb to mobilise US $1 billion in financing to countries committed to protecting their tropical forests. * Land-use, Land-use Change and Forestry (LULUCF) is included in 121 NDCs (out of 167 NDCs) but only 11 provide a lulucf target that can be “fully quantified. * Although over 70 per cent of ndcs are estimated to contain references to efforts in the forest sector, 20 per cent of these include quantifiable targets, and 8 per cent include targets expressed in tonnes of CO2 equivalent. * In its plan to become carbon neutral by 2060, China has included massive tree-planting efforts and the restoration of wetlands to remove one-third of its emissions

Answer 180

amount of emissions sequestered or released from forests and other land-based ecosystems are not easy to calculate and the margin of error is still huge. a 2018 paper published in Nature Climate Science finds a gap of 5.5 GtCO2 a year—equivalent to the annual emissions of the US—between different methodologies for estimating net emissions from forests The factors influencing land CO2 fluxes—the exchange between emissions and absorption—are not fully understood even by climate scientists issues like different rates of CO2 absorption in different forest biomes. growing forests have higher rates of absorption compared to standing forests. Then there is difficulty in accurately accounting removal of forests in the mathematics of sink—in case of deforestation the carbon matter is removed from the forest, whereas when a tree dies in the forest, its carbon matter is transferred to the soil, where it can be stored for thousands of years. Then there is the complicated question of "permanence”—the stored carbon in vegetation and soils can be released at any time due to disturbances such as flood, drought, fire, pest outbreaks or poor management. ipcc's srccl report also notes that afforestation, reforestation, and agroforestry “do not continue to sequester carbon indefinitely”, eventually “net annual removal of CO2 from the atmosphere declines towards zero”

Answer 181

—appropriation of land and resources for environmental ends The potential sinks are mostly located within the borders of developing countries and face high rates of forest loss, such as the Amazon, Congo Basin, southeast Asia A study in *Nature Sustainability* notes that indigenous people, though account for 5 per cent of the global population, own 37 per cent of all remaining natural lands in the world. at least 1,075 GtCO2 is stored in the collective forestlands of indigenous peoples and local communities In fact, deforestation rates are significantly lower in indigenous and tribal territories, where governments have formally recognised collective land rights.

Answer 182

Brazil, for instance, has protected 190 million ha of Amazon rainforests under different regimes. This protection stopped deforestation and increased the carbon sequestration from Amazon between 2004 to 2009. One study calculated that the opportunity costs for the Brazilian Amazon protected network is $141 billion, or $5.4 per tonne of carbon

Answer 183

methodology to assess whether and to what extent external drivers alter the likelihood of a specific extreme event. Weather attribution scientists have analysed 405 extreme weather events between 2003 and 2021 and found human fingerprints in almost 80 per cent of them in event attribution, we try to understand if these extreme events are becoming more frequent or more intense. For this, scientists deploy statistical techniques that sift through the long-term data available for the region to find previous extremes and analyse changes in them over time. Then a climate model—essentially a programme that simulates many thousands of years of weather conditions—is used to measure the chance of getting such an event today, when the atmosphere is loaded with high temperature and ghg emissions (called the factual), and also probability of the event before climate started changing (counterfactual) eg. While analysing the recent heatwave in western North America, wwa team found that in the counterfactual there was no such event; the models could not simulate such an event in the region in the absence of climate change. Thus they said that the record temperatures were a consequence of human-induced climate change

Answer 184

by MoES It is India’s first-ever national forecast on the impact of global warming on the subcontinent in the coming century. These projections, based on a climate forecasting model developed at the Indian Institute of Tropical Meteorology (IITM), Pune, will be part of the next report of IPCC

Answer 185

* Between 1900 and 2018, the average temperatures of India rose by 0.7°C. This rise in temperatures has been largely attributed to global warming due to GHG emissions and land use and land cover changes. However, it has also been slightly reduced by the rising aerosol emissions in the atm * future predictions * Worst case scenario * In a worst-case scenario, average surface air temperatures over India could rise by up to 4.4°C by the end of the century as compared to the period between 1976 and 2005. * By 2100, the frequency of warm days and warm nights might also increase by 55% and 70% respectively, as compared to the period 1976-2005 under the RCP 8.5 scenario. * Intermediate scenario * Under an intermediate scenario, the country’s average temperature could rise by up to 2.4°C. * The rise in temperatures will be even more pronounced in the Hindu Kush-Himalayan region where the average could reach 5.2°C. * The incidences of heat waves over the country could also increase by three to four times. Their duration of occurrence might also increase which was already witnessed by the country in 2019.

Answer 186

* Overall rainfall during the monsoon season has decreased by 6% between 1950 and 2015. * In the past few decades, there has been an increased frequency of dry spells during the monsoon season that has increased by 27% between 1981-2011, as compared to 1951-1980. * The intensity of wet spells has also increased over the country, with central India receiving 75% more extreme rainfall events between 1950 and 2015. * For example: Monsoon seasons of 2018 and 2019 where dry spells were broken by extremely heavy rainfall spells, creating a flood and drought cycle in many regions in India. * Monsoon rainfall could change by an average of 14% by 2100 that could go as high as 22.5%. It is not mentioned if this change will be an increase or a decrease but still represents variability.

Answer 187

F China on August 16 said it has produced its first global carbon flux dataset, using information gathered from its carbon dioxide (CO2 ) monitoring satellite TanSat. With this, China has become the third country after Japan and the US to monitor the global carbon flux, or amount of CO2 exchanged between the world's carbon sinks. The dataset will help it devise strategies reduce emissions.

Answer 188

* Raise the lower limit of thickness of plastic carry bags from 40 to 50 microns and stipulate minimum thickness of 50 micron for plastic sheets also to facilitate the collection and recycling of plastic waste. * Expand the applicability jurisdiction from the municipal area to rural areas, because plastic has reached rural areas also. * To usher in the responsibilities of producers and generators, both in plastic waste management system and to introduce collect back system of plastic waste by the producers/brand owners, as per extended producers responsibility. * To introduce collection of plastic waste management fee through pre-registration of the producers, importers of plastic carry bags/multilayered packaging and vendors selling the same for establishing the waste management system. * To promote the use of plastic waste for road construction as per Indian Road Congress guidelines or energy recovery, or waste to oil etc. for gainful utilization of waste and also address the waste disposal issue.

Answer 189

* Applicability: * to every waste generator, local body, manufacturer, **importers and producer** * **Rural areas** have been brought in the ambit of these Rules since plastic has reached to rural areas also. **Responsibility for implementation of the rules is given to the Gram Panchayat.** * **2011 rules were applicable to municipal areas only** * **Extended Producer Responsibility**: Previously, EPR was left to the discretion of the local bodies. First time, the producers (i.e persons engaged in manufacture, or import of carry bags, multi-layered packaging and sheets or like and the persons using these for packaging or wrapping their products) and brand owners have been made responsible for collecting waste generated from their products. They have to approach local bodies for formulation of plan/system for the plastic waste management within the prescribed time frame. **They need to establish a collect back system for the plastic waste generated due to their products.** * **Minimum Thickness of Plastic Carry Bags: increased from 40 to 50 microns.** * **Encourage reuse of plastic** in various applications- road construction, waste to oil, waste to energy * **State Pollution Control Board (SPCBs) will not grant/renew registration of plastic bags, or multi-layered packaging unless the producer proposes the action plan** endorsed by the concerned State Development Department. * **Producers to keep a record of their vendors to whom they have supplied raw materials for manufacturing carry bags**, plastic sheets, and multi-layered packaging. This is to **curb** the manufacturing of these products in **unorganised sector**. * **Plastic carry bag will be available only with shopkeepers/street vendors pre-registered with local bodies on payment of certain registration fee**. * Central Pollution Control Board (**CPCB**) has been mandated to formulate the **guidelines** for thermoset plastic (plastic difficult to recycle). In the earlier Rules, there was no specific provision for such type of plastic.

Answer 190

* The rules do not deal with the informal sector of waste collection. * These rules do not focus on reducing plastic waste as there is no mention on how to reduce plastic waste in the new rules. While it has focused on the use of plastic carry bags by increasing the minimum thickness from 40 microns to 50 microns, but it is silent on the other forms of plastics such as the mineral water bottles (PET). * The producers have not shown any interest despite various interventions across the country by government and civic societies. * It lacks steps to spread awareness among the masses about plastic waste.

Answer 191

Extended producer responsibility (EPR) is a critical policy mechanism that helps advance the circular economy, decreases the environmental impact from a product and its packaging, and promotes the principle of “polluter pays” by holding the producer accountable for the entire lifecycle of the product. Obj: * Integration of environmental costs * Improved waste management * Reduction of disposal * Reduction of burden on municipalities * Design of environmentally sound products Plastic Waste Management Rules, 2016 introduced the concept of EPR to manage plastics in India. MoEFCC) released a draft EPR policy for management of plastic waste in India on October 6, 2021

Answer 192

* **Include the first principle of waste management — plastic waste reduction / minimisation — in the EPR mandate.** Unfortunately, this is perceived and left alone as a theoretical option and we never try to translate this into action. The draft EPR policy is no different. It talks about all the forms of management from reuse to end of life disposal, conveniently leaving out the most-preferred option of plastic waste reduction / minimisation. Through the new EPR policy in India, the brand owners should be encouraged to gradually decrease the amount of plastics they introduce in the market by adopting alternatives such as paper, glass, metals, among other things. This should be strengthened by incentives in the form of EPR certificates to the brand owners who diversify their packaging and reduce the amount of plastics they put out in the market. * **Compostable and biodegradable plastics should have an EPR mandate of collection and processing.** Globally, 1 per cent of the entire plastics produced are from non-fossil sources and are known by various names like bio-plastics, compostable plastics and biodegradable plastics. This means that India generates more than 250 tonnes of compostable and biodegradable plastic every day.Whether a biodegradable or a compostable plastic breaks down and the rate of breakdown depends on the conditions it is exposed to once it is disposed of. India does have standards for compostable plastic (Schedule I of the Plastic Waste Management Rules, 2021). But the certification and labelling mechanism is very weak and needs to be addressed through policy. * **Ambiguity around the action plan to be submitted by PIBOs (Producers, Importers and Brand Owners):** It is mandatory for PIBOs to submit an action plan, according to the draft EPR policy. The template for the action plan, however, is not discussed or provided anywhere. The “must, should and could” elements have not been talked about.

Answer 193

* The amended Rules lay down that the phasing out of Multilayered Plastic (MLP) is now applicable to MLP, which are “non-recyclable, or non-energy recoverable, or with no alternate use.” * The amended Rules also prescribe a central registration system for the registration of the producer/importer/brand owner. * The centralised registration system will be evolved by Central Pollution Control Board (CPCB) for the registration of the producer/importer/brand owner.

Answer 194

1. **Prohibition** of manufacture, import, stocking, distribution, sale and use of **SUP**, including **polystyrene and expanded polystyrene**, commodities from the 1st July, 2022. This covers – * **ear buds** with plastic sticks, **plastic sticks for balloons**, **plastic flags**, candy sticks, ice-cream sticks, **polystyrene [Thermocol] for decoration** * **plates, cups, glasses, cutlery, wrapping or packing films** around sweet boxes * **invitation cards, cigarette packets, plastic or PVC banners** less than 100 micron, stirrers * **Sachets**: According to the **Plastic Waste Management Rules, 2016**, there is also a complete ban on sachets using plastic material for storing, packing or selling gutkha, tobacco and pan masala. * As per the ministry: The choice for the first set of single-use plastic items for the ban was based on “**difficulty of collection, and therefore recycling**”. ***_This is in line with CG's decision in 2019 to free India of single use plastics by 2022_*** 2. **Thickness** of plastic carry bags to be **increased from 50 microns –** * **to 75 microns from 30th September, 2021** * **to 120 microns from the 31st December, 2022** Currently the Plastic Waste Management Rules, 2016, prohibits manufacture, import, stocking, distribution, sale and use of carry bags and plastic sheets less than 50 microns in thickness in the country. 1. This is to stop littering due to lightweight plastic carry bags, and allow their reuse. 2. **Guidelines for Extended Producer Responsibility/EPR**(as per Plastic Waste Management Rules, 2016) has been given **legal force through the 2021 Rules, for effective implementation.** * EPR - Environmental policy approach in which a producer’s responsibility for a product is extended to the post-consumer stage of a product’s life cycle. 3. The plastic packaging waste shall be collected and managed in an environmentally sustainable way through the **Extended Producer Responsibility (EPR) of the Producer, importer and Brand owner.** 4. CPCB along with state pollution bodies, will monitor the ban, identify violations, and impose penalties already prescribed under the Environmental Protection Act. 5. enforcement * **Monitoring by CPCB and SPCBs** that will report to the Centre regularly. * **Stop raw materials supply**: for example, to all petrochemical industries — to not supply raw materials to industries engaged in the banned items. * **Directions to industries:** SPCBs and Pollution Control Committees will modify or revoke consent to operate issued under the **Air/Water Act** to industries engaged in single-use plastic items. * **Fresh licensing required**: Local authorities have been directed to issue fresh commercial licenses with the condition that SUP items will not be sold on their premises, and existing commercial licences will be cancelled if they are found to be selling these items. * **Encouraging compostable plastics:** CPCB has issued one-time certificates to 200 manufacturers of compostable plastic and the BIS passed standards for biodegradable plastic. * **Penalty**: Those found violating the ban can be penalised under the Environment Protection Act 1986 – which allows for imprisonment up to **5 years, or a penalty up to Rs 1 lakh, or both.** * Violators can also be asked to pay **Environmental Damage Compensation** by the SPCB. Notably, in the 4th UN Environment Assembly held in 2019, India had piloted a resolution on addressing single-use plastic products pollution.

Answer 195

* Previously, almost **25 Indian States p**reviously banned plastic at the state level. However, these bans had a very **limited impact** in reality because of the widespread use of these items. * **Consensus on SUP in UN**: This year, 124 countries, parties to the United Nations Environment Assembly, including India, signed a resolution to draw up an agreement which will in the future make it **legally binding for the signatories to address the full life of plastics from production to disposal**, to end plastic pollution. * **68 countries** have plastic bag bans with varying degrees of enforcement * **Bangladesh**: Bangladesh became the first country to **ban thin plastic bags** in 2002. * **China**: China issued a ban on plastic bags in 2020 with a phased implementation. * **EU**: EU bans certain single-use plastics for which alternatives are available.

Answer 196

While the total ban on the use of plastic sounds a great idea, its feasibility seems difficult at this hour, especially in the absence of workable alternatives. Alternatives 1. Bio-plastics: materials biosourced or biodegradable or both and are made from renewable biomass resources (eg. corn starh, sugarcane, cassava) 2. Bio-degradable plastic: plastics which undergo complete degradation by biological processes under ambient env 3. compostable plastic: plastics that undergo degradation by biological processes during composting 4. Oxo-Degradable: these are conventional plastics such as PE, which ainclude an additive to help them break down into smaller fragments, which could lead to microplastic leakage in the env

Answer 197

B BPA stands for bisphenol A, **an industrial chemical that has been used to make certain plastics and resins since the 1950s**. BPA is found in polycarbonate plastics and epoxy resins. Polycarbonate plastics are often used in containers that store food and beverages, such as water bottles.

Answer 198

Four categories of plastic packaging specified: 1. Category one will include **rigid plastic packaging** 2. Category two will include **flexible plastic packaging of single layer or multilayer** (**more than one layer with different types of plastic**), **plastic sheets and covers** made of plastic sheet, carry bags, plastic sachet or pouches. 3. Category three will include **multi-layered plastic packaging** (**at least one layer of plastic and at least one layer of material other than plastic**). 4. Category four includes **plastic sheet or like used for packaging as well as carry bags made of compostable plastics.** guidelines also include: ● Specifications for reuse, recycling, use of recycled plastic content, and end-of-life disposal of non-recyclable plastic packaging. ● setting up a **centralised online portal by Central Pollution Control Board (CPCB)** for the registration as well as filing of annual returns by producers, importers and brand-owners, plastic waste processors of plastic packaging waste by March 31. ● **Producers of plastic packaging will have to manage 35% of the ‘Q1’ waste in metric tonnes in 2021-22.** Q1 is calculated by adding the last two years’ average weights of plastic packaging material sold and pre-consumer plastic packaging waste, and subtracting the annual quantity of plastic packaging supplied to brand owners. ● The **EPR target will be increased to 70% in 2022-23 and 100% from 2023-24 onwards.** ● The **recycling obligation for producers will be 50% for rigid plastics in 2024-25, 60% in 2025-26, 70% in 2026-27, and 80% from 2027-28 onwards.** ● **Environmental compensation shall be levied based upon polluter pays principle**, **with respect to non-fulfilment of EPR targets** by producers, importers and brand owners, for the purpose of protecting and improving the quality of the environment and preventing, controlling and abating environment pollution. ● **For the first time, the guidelines allow for the sale and purchase of surplus extended producer responsibility certificates**. Thus setting up a **market mechanism** for plastic waste management.

Answer 199

* close to 26,000 tons of plastic waste is generated across India every day, of which more than 10,000 tons (~40%) stays uncollected * **9.46 million tonnes** of plastic waste annually * **43%** is used for packaging, most of which are of **single-use plastic**. * According to a **Federation of Indian Chambers of Commerce and Industry (FICCI)** study the plastic processing industry is estimated to grow to 22 million tonnes (MT) a year by 2020 from 13.4 MT in 2015 and nearly half of this is single-use plastic. * India’s **per capita plastic consumption** of less than 11 kg, is nearly a tenth of the United States of America (109 kg). Single use plastic * **India features in the top 100 countries** of single-use plastic waste generation – at rank 94 (the top three being Singapore, Australia and Oman). * India’s domestic production of SUP is **8 million metric tonnes** annually, and its import of **2.9 MMT.** * India’s per capita generation is **4 kg**. * The largest share of single-use plastic is that of **packaging** – with as much as **95%** of single-use belonging to this category – from toothpaste to shaving cream to frozen foods.

Answer 200

* Plastic production has risen exponentially in the last decades and now amounts to some 400 million tons per year– a figure set to double by 2040. * By 2050 greenhouse gas emissions associated with plastic production, use and disposal would account for 15 percent of allowed emissions, under the goal of limiting global warming to 1.5°C (34.7°F). * More than 800 marine and coastal species are affected by this pollution through ingestion, entanglement, and other dangers * Some 11 million tonnes of plastic waste flow annually into the oceans. This may triple by 2040. * A shift to a circular economy can reduce the volume of plastics entering oceans by over 80 per cent by 2040; reduce virgin plastic production by 55 per cent; save governments US$70 billion by 2040; reduce greenhouse gas emissions by 25 per cent; and create 700,000 additional jobs – mainly in the global south * **As per the Minderoo Foundation report (2021)**: single-use plastics account for a **third of all** plastic produced globally, with **98% manufactured from fossil fuels**. * Single-use plastic also accounts for the majority of plastic discarded – 130 million metric tonnes globally in 2019 — all of which are burned, buried in landfills or discarded directly into the environment. * **GHG emission:** On the current trajectory of production, it has been projected that single-use plastic could account for 5-10% of greenhouse gas emissions by 2050.

Answer 201

the new rules conveniently leave out several plastic items with high environmental impact, such as plastic bottles for food and nonfood applications, cigarette filters, multi-layered packaging as well as plastic films. For example, the list exempts plastic packaging, which is alone responsible for almost 60 per cent of the plastic waste generated in the country continued exemption of multi-layered plastics: recommended to be restricted since the draft of first Plastic waste mgmt rules in 2009, bt dropped in actual rules notified in 2011; 2016 rules recommended phasing them out in 2 yrs bt was again diluted in 2018 rules which suggested burning them for “energy recovery” While all the 20 items to be phased out by next year are mostly produced by local plastic manufacturers, operating at a small or medium scale without branding, the ones that have been exempted are generated by fast moving consumer goods (fmcg) companies and other multinationals protects the exempted plastic goods in the future as well since it declares that any future notification banning them after 2021 rules will come into effect after the expiry of 10 yrs frm the date of its publication

Answer 202

The government announced the ban on single-use plastic in August 2021, following its 2019 resolution to address plastic pollution in the country. ● The ban on most single-use plastics will take effect from July 1, 2022. In 2019, the Union government in a bid to free India of single-use plastics by 2022, had laid out a multi-ministerial plan to discourage the use of single-use plastics across the country. The strategy: A government committee has identified the single use plastic (SUP) items to be banned based on an index of their utility and environmental impact. It has proposed a three-stage ban: 1. The first category of SUP items proposed to be phased out are plastic sticks used in balloons, flags, candy, ice-cream and ear buds, and thermocol that is used in decorations. 2. The second category, proposed to be banned from July 1, 2022, includes items such as plates, cups, glasses and cutlery such as forks, spoons, knives, straws, trays; wrapping and packing films used in sweet boxes; invitation cards; cigarette packets; stirrers and plastic banners that are less than 100 microns in thickness. 3. A third category of prohibition is for non-woven bags below 240 microns in thickness. This is proposed to start from September next year.

Answer 203

Mousuni island of Sunderbans, is encircled by a river, a creek and the Bay of Bengal. A steady rise of sea, particularly along its western and southern coast, is continuously eroding its outline. A 2010 study shows that the island has lost 64 hectares between 2001 and 2009. A 2020 study estimate that the island is receding at 8.75 per cent a year compared to 4.18 per cent during 1977-1989, and will soon attend the fate of neighbouring Ghoramara and Jambudwip islands that are sinking fast While 2,200 families have already been displaced or affected by the rising sea and extreme weather disasters like cyclones and storms, the remaining either temporarily shift to safer places before any supermoon that bring stronger tides or are preparing to abandon the island for ever. Since 2019, three powerful cyclones—Yaas in May 2021, Amphan in May 2020 and Bulbul in November 2019— have battered this West Bengal island Repeated cyclones have hit the fishing community hard. Most of their boats have been destroyed. The daily wagers who worked on these boats now try to fish with small nets all day long. They are also forced to sell their catch locally as they cannot afford to take such a small quantity to the market

Answer 204

* Habitat loss * growth of population of wild animals. India will be most-affected by human-wildlife conflict because it had the world’s second-largest human population as well as large populations of tigers, Asian elephants, one-horned rhinos, Asiatic lions and other species * encroachment by people into traditional wild space and animal sanctuaries. * changing cropping patterns that attract wild animals to farmlands * unsustainable development: Animal usual corridors blocked by **highways, railway tracks, and factories**. This results in **ecological dislocation** of sorts, wherein endangered wild animals like tigers either cause distress or land themselves in trouble * **Failure of government measures:** **‘Human-Wildlife conflict mitigation measures** are dysfunctional, haphazardly implemented, and therefore not effective * **Location of animals outside protected areas:** Wildlife experts estimate that **29 percent of the tigers** in India are outside the protected areas. Wildlife experts claim that territorial animals **do not have enough space** within reserves and their prey do not have enough fodder to thrive on.

Answer 205

* Emulating Sonitpur Model * **Sonitpur Model: WWF India** had developed the **‘Sonitpur Model’** during 2003-2004 by which community members were connected with the state forest department. They were given **training on how to work** with them to drive elephants away from crop fields safely. Afterward, crop **losses dropped to zero for four years running**. Human and elephant deaths also reduced significantly. * **Empower gram panchayats**in dealing with the problematic wild animals as per the **Wildlife (Protection) Act, 1972.** * **Utilize add-on coverage** under the **Pradhan Mantri Fasal Bima Yojna**for crop compensation against crop damage due to HWC. * **Augment fodder and water sources** within the forest areas. * **Other measures:** **inter-departmental committees** at the local/state level, adoption of early warning systems, creation of barriers, dedicated circle wise Control Rooms with toll-free hotline numbers which could be operated on a 24X7 basis.

Answer 206

1. Globally, conflict-related killing affects more than 75 per cent of the world’s wild cat species. It also affects polar bears and Mediterranean monk seals as well as large herbivores such as elephants. 2. Over 500 elephants were killed between 2014-2015 and 2018-2019, mostly due to human-elephant conflict. 3. During the same period, 2,361 people were killed as a result of conflict with elephants. 4. Between 2018-19 and 2020-21, 222 elephants were killed by electrocution across the country, 45 by trains, 29 by poachers and 11 by poisoning. Among tigers, too, 29 were killed by poaching between 2019 and 2021, while 197 tiger deaths are under scrutiny. 5. The Tiger T23 killing 4 individuals in villages around Mudumalai Tiger reserve 6.

* Obj: 1. Protect the forest along with its flora, fauna and preserving the integrity and territory of the forests 2. arrest the loss of forest biodiversity 3. prevent forest lands being converted into agricultural, grazing or any other commercial purposes 1. The Act restricts the state government and other authorities to take decisions first without permission from theCG wrt non-forest purposes i.e. clearing forest lands for planting of- Tea, coffee, spices, rubber, palms, iol bearing plants and medicinal plants 2. Prior permission of the Central Government is essential for De-reservation/ Diversion of forest land for non-forestry purposes. 3. The Forest Conservation Act gives complete authority to the Central government to carry out the objectives of the act. 4. The Act levies penalties in case of violations of the provisions of FCA. 5. The Forest Conservation Act will have an advisory committee which will help the Central government with regard to forest conservation. * **Promote afforestation**: This act put certain conditions on the user(s) that need to deposit the required amount to undertake compensatory afforestation for mitigate the negative impact of forest land diversion.

Answer 210

prohibits the lease of forest land to anybody other than the government. It enhances conservation, plantation and increase of forest cover to an average of 30%.

Answer 211

* **Infrastructure is allowed**: The Act made provision for allowing some non-forest activities in forests without cutting trees with prior approval of the Central government. These activities include the setting of transmission lines, seismic surveys, exploration, drilling, and hydroelectric projects. * **Total ban deforestation**: Wildlife sanctuaries, National Parks, etc. are totally prohibited for any exploration or survey without prior approval of the Central government even if no tree felling is involved. * **More crops under NFA**: Cultivation of tea, coffee, spices, rubber, mulberry for rearing silkworms, and cash crops are included under non-forestry activities and are not allowed in reserve forests. * **Mining**: Mining is a non-forestry activity and prior approval of the Central government is mandatory. * Environmental Impact Statement.

Answer 212

* Several Ministries have expressed resentment on how the Act was being interpreted over the right of way of railways, highways * As of today, a landholding agency (Rail, NHAI, PWD, etc.) is required to take approval under the Act and pay stipulated compensatory levies such as [**Net Present Value (NPV),**](https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.insightsonindia.com/2020/09/12/net-present-value-npv/&ved=2ahUKEwiW84-b-bTzAhVVfisKHcxFCcgQFnoECAQQAQ&usg=AOvVaw0hZWyxAvaQEgvGqJKvbo3R) [**Compensatory Afforestation (CA),**](https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.insightsonindia.com/2019/08/30/campa/&ved=2ahUKEwjzxL2v-bTzAhXXZSsKHdSIAakQFnoECAQQAQ&usg=AOvVaw1yw3ZvlH61JcVPzW4MGh7j) for use of such land which was originally been acquired for non-forest purposes. * questions on the legal definition of “forest”. * States have been told to provide a definition of what constitutes a forest, but several haven’t given them because this has political consequences. All of this has led to conflicting interpretations of the FCA through the years.

Answer 213

The 1996 Supreme Court judgment (in **TN Godavarman Thirumulpad versus Union of India and Others case)** paved the way for the calculating: 1. The net present value, or the economic value of the portion of forest being razed for development work that had to be paid by project proponents. 2. The creation of a compensatory afforestation fund. 3. Providing non-forestry land in lieu of the diverted forest. 4. **Before the 1996** Supreme Court judgement in **TN Godavarman Thirumulpad versus Union of India and Others,** forest land was only that as was defined by the 1927 Forest Act. But the court included all areas which are recorded as ‘forest’ in any government record, irrespective of ownership, recognition and classification.

Answer 214

1. Absolve **agencies involved in national security projects and border infrastructure projects** from obtaining **prior forest clearance** from the Centre. Such a permission is necessary under the Forest Conservation Act (FCA). 2. **Exempt land acquired before 1980 —** before the FCA came into effect — by public sector bodies such as the Railways. 3. Facilitating **private plantations for harvesting and exploration or extraction of oil and natural gas** deep beneath forest land by drilling holes from outside the forest areas. 4. **Building in forests:** To ease the grievances of the individuals whose land fall in state specific private forests act or within the purview of dictionary meaning of forest, the ministry has proposed to allow them the right to construct structures for bonafide purposes including forest protection measures and residential units up to an area of 250 sq mtr as one time relaxation. 5. **Punishments:** Make offences under the modified Act punishable with simple imprisonment for a period which may extend to one year and make it cognisable and non-bailable. 6. It also has provisions for **penal compensation to make good for the damage already done.**

Answer 216

Water privatization – when private corporations buy or operate public water utilities is often suggested as a solution to municipal budget problems and aging water systems.

Answer 217

* UN World Water Report of 2006 notes that “*there is enough water for everyone” and “water insufficiency is often due to mismanagement, corruption, lack of appropriate institutions, bureaucratic inertia and a shortage of investment in both human capacity and physical infrastructure*“. * Fears over water scarcity and the need to **manage water efficiently by giving it an economic value** is the starting point from where privatization is pushed. * Critics of public supply of water insisted on **the state’s inability to operate efficiently** and created a case for a shift towards market-based water governance.

Answer 218

* By privatizing water and sewer systems, **local government officials abdicate control over a vital public resource**. * Privatization **limits public accountability**. Multinational water corporations are primarily accountable to their stockholders, not to the people they serve. * Loss of **transparency**. Private operators usually restrict public access to information and do not have the same level of openness as the public sector. * The objectives of a profit-extracting water company i.e. profitability can conflict with the public interest. * eg.Private water companies are unlikely to adopt the same criteria as municipalities when deciding where to extend services. They are prone to **cherry-picking service** areas to avoid serving low-income communities where low water use and frequent bill collection problems could hurt corporate profits. * As a result of price hikes, service disconnections, inadequate investment and other detrimental economic consequences, water privatization often **interferes with the human right** to water. * Empirical evidence indicates that **there is no significant difference in efficiency between public and private water provision**. researchers have found that the water market is “rarely competitive.” The only competition that can exist is the competition for the contract, and there are only a few private water companies that bid to take over municipal water systems. Once a contract is awarded, the winning company enjoys a monopoly. *

Answer 219

* In 2012, municipal body in Nagpur handed over its water supply to a subsidiary of the French water corporation, Veolia, for 25 years. Since then, the project has seen allegations of corruption, four increases in water tariffs, cost overruns, and delays in plugging leaks. The municipal body’s financial losses from water works has reportedly increased by Rs 60 crore per annum, leading to demands, from both opposition parties and the local community, for the ouster of the private player. * Smaller experiments in privatisation in Khandwa, Mysore, and Aurangabad, among others, have followed similar trajectories. * Water services Latur were handed over to a private operator — but within a few years, the Maharashtra water supply department had to take back control after high tariffs without any improvement in water quality triggered strong protests.

Answer 220

A 2014 study by the Transnational Institute lists 180 case studies in the last 15 years of public authorities wresting back control from private players — including in capital cities such as Paris, Berlin, Buenos Aires, Budapest, Kuala Lumpur and Bogota. 75% of these cases have been in high-income countries. T

Answer 221

* Instead of privatizing water systems, municipalities can partner together through public-public partnerships. Public partners are more responsive, reliable and cost-effective than private water companies. Intermunicipal cooperation, interlocal agreements and bulk purchasing consortiums can improve public services and reduce costs, while allowing communities to retain local control. * As the recently drafted National Water Framework Law (NWFL) states, “water is the common heritage of the people of India; an inseparable part of a people’s landscape, society, history and culture; and in many cultures, a sacred substance, being venerated in some as a divinity”. Such a resource must never be privatised. * the Public Trust Doctrine enunciated by the Supreme Court, rather than privatisation or nationalisation, is the answer to India’s water problems.

Answer 222

* The value of goods and services provided by coral reefs is estimated to be $2.7 trillion per year. This includes $36 billion in coral reef tourism. * Corals occupy less than one per cent of the ocean floor but over one billion people benefit directly from the reefs. 1. In the last decade, the world lost about 14 per cent of its coral reefs. 2. **Threats:** Ocean-acidification, warmer sea temperatures and local stressors such as overfishing, pollution, unsustainable tourism and poor coastal management. 3. **Impact of global warming:** Coral reefs across the world are under relentless stress from warming caused by climate change. [**Coral bleaching**](https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.insightsonindia.com/2020/03/07/what-causes-coral-bleaching-at-the-great-barrier-reef/&ved=2ahUKEwjVu-Xcj7XzAhVf63MBHRJGDy4QFnoECAUQAQ&usg=AOvVaw0H7R75lTsJWjvlDMQB2jWz) **events** caused by rise in elevated sea surface temperatures (SST) were responsible for coral loss. 4. **Loss of hard coral cover:** There has been a steady decrease in hard coral cover in the last four decades since 1978 when the world lost nine per cent of its corals. The decrease is disconcerting because live hard coral cover is an indicator of coral reef health. 5. [**Algal bloom**](https://www.google.com/url?sa=t&source=web&rct=j&url=https://www.insightsonindia.com/wp-content/uploads/2016/10/Issue-of-Algal-Bloom.pdf&ved=2ahUKEwjppMPtj7XzAhVUXHwKHU4WAGoQFnoECCgQAQ&usg=AOvVaw1t9zVvx3QV3FuZtyjGYlkP)**:** Algal bloom on coral ridges are a sign of stress on the structures. Since 2010, the amount of algae on the world’s coral reefs has increased by about 20 per cent.

Answer 223

The **Coral Triangle (CT)** is a roughly triangular area in the tropical waters around [Indonesia](https://en.m.wikipedia.org/wiki/Indonesia), [Malaysia](https://en.m.wikipedia.org/wiki/Malaysia), [Papua New Guinea](https://en.m.wikipedia.org/wiki/Papua_New_Guinea), the [Philippines](https://en.m.wikipedia.org/wiki/Philippines), the [Solomon Islands](https://en.m.wikipedia.org/wiki/Solomon_Islands) and [Timor-Leste](https://en.m.wikipedia.org/wiki/Timor-Leste). This area contains at least 500 species of reef-building [corals](https://en.m.wikipedia.org/wiki/Coral) in each [ecoregion](https://en.m.wikipedia.org/wiki/Ecoregion) The Coral Triangle is located between the [Pacific](https://en.m.wikipedia.org/wiki/Pacific) and [Indian](https://en.m.wikipedia.org/wiki/Indian_Ocean) oceans and encompasses portions of two [biogeographic regions](https://en.m.wikipedia.org/wiki/Biogeography): the Indonesian-Philippines Region, and the Far Southwestern Pacific Region. Known as the "[Amazon](https://en.m.wikipedia.org/wiki/Amazon_basin) of the seas", it covers 5.7 million square kilometres of ocean waters. It contains more than 76% of the world's shallow-water reef-building coral species, 37% of its reef fish species, 50% of its razor clam species, six out of seven of the world's sea turtle species, and the world’s largest mangrove forest. In 2014, the [Asian Development Bank](https://en.m.wikipedia.org/wiki/Asian_Development_Bank) (ADB) reported that the [gross domestic product](https://en.m.wikipedia.org/wiki/Gross_domestic_product) of the marine ecosystem in the Coral Triangle is roughly $1.2 trillion per year and provides food to over 120 million people.

Answer 228

Bottom trawling, an ecologically destructive practice, involves trawlers dragging weighted nets along the sea-floor, causing great depletion of aquatic resources. * Bottom trawling captures juvenile fish, thus exhausting the ocean’s resources and affecting marine conservation efforts. This practice was started by Tamil Nadu fishermen in Palk Bay and actively pursued at the peak of the civil war in Sri Lanka. **India v Sri Lanka:** * This practice has been banned in Sri Lanka and there have been agitations for stringent enforcement of the law. * use of bottom trawlers by the Tamil Nadu fishermen isopposed in Sri Lanka’s Northern Province on the ground that trawling damages the marine ecosystem. * The Indian side had agreed twice — in 2010 and 2016 — to phase out and end the practice of bottom trawling. But it has not ended yet **Solution to Bottom Trawling: Deep Sea Fishing**: The activity of catching fish that live in the deep parts of the sea/ocean is called deep-sea fishing. The depth of water should be at least 30 meters to be considered a deep sea fishing zone. The boats are designed in such a way that fishermen get access to the deeper parts of the ocean and fish species. It is practiced worldwide, especially in the coastal areas with no ecological damage. Govt initiative: Palk Bay scheme: * Launched in July 2017 under the Blue Revolution programme. * The scheme is financed by the Union and the State Governments with beneficiary participation. * It had envisaged the provision of 2,000 vessels in three years to the fishermen of the State and motivate them to abandon **bottom trawling.**

UNHCR has unanimously voted for **recognising a clean, healthy and sustainable environment as a universal right.** The resolution emphasises “the rights to life, liberty and security of human rights defenders working in environmental matters, referred to as **environmental human rights defenders.”** * Environmental defenders across the globe are subject to constant physical attacks, detentions, arrests, legal action and smear campaigns. * Some 200 environmental defenders have been murdered in 2020 alone. Significance: 1. Stronger environmental laws and policies. 2. Improved implementation and enforcement. 3. Greater public participation in environmental decision-making. 4. Reduced environmental injustices. 5. A level playing field with social and economic rights. 6. And better environmental performance. issues: * A human right to a safe, clean, healthy and sustainable environment has not been agreed in any human rights treaty and it is yet to emerge as a customary right. * Recognising rights without due consideration and a common understanding at an international level of what they comprise creates ambiguity. * Individuals cannot know what they can legitimately claim from the State, and the State has no clear understanding of the protection it is obliged to afford to the individual. * Besides, **human rights resolutions are not legally binding instruments,** and as such the recognition of the right in this resolution does not bind States to its terms.

Answer 233

The 1972 United Nations Conference on the Environment in Stockholm was the first world conference to make the environment a major issue. The Stockholm Declaration, which contained 26 principles, placed environmental issues at the forefront of international concerns and marked the start of a dialogue between industrialized and developing countries on the link between economic growth, the pollution of the air, water, and oceans and the well-being of people around the world. One of the major results of the Stockholm conference was the creation of the [United Nations Environment Programme (UNEP)](https://www.unenvironment.org/).

Answer 236

This is the right time for India to mull setting up a climate law while staying true to its goals of climate justice, carbon space and environmental protection. 1. our existing laws are not adequate to deal with climate change. We have EPA 1986, Air Act 1981 and Water Act 1974. Yet, climate is not exactly water or air. Which law would cover the impacts of a cyclone, for instance or work to reduce future climate impacts? 2. neither are we ready to tackle environmental/climate violations. The Environment (Protection) Act is grossly inadequate to deal with violations on climate. Clause 24 of the Act, “Effect of Other Laws”, states that if an offence is committed under the EPA or any other law, the person will be punished under the other law (for example, Code of Criminal Procedure). This makes the EPA subordinate to every other law. 3. there is a need to integrate climate action — adaptation and mitigation — and monitor progress. Comprehensive climate action is not just technological (such as changing energy sources or carbon intensity), but also nature-based (such as emphasising restoration of ecosystems, reducing natural hazard and increasing carbon sinks.) 4. Climate action cannot come by furthering sharpening divides or exacerbating poverty, and this includes our stated renewable energy goals. The 500 Gigawatt by 2030 goal for renewable, solar or wind power for example (of installed power capacity from non-fossil sources), can put critically endangered grassland and desert birds such as the Great Indian Bustard at risk, as they die on collision with wires in the desert. 5. We have the BEE, but we also need overall carbon efficiency that looks beyond electronics. How could intelligent interventions be made for reduction of footprints, along with common sense, and practical public health interventions which are unaccounted for so far? In a recent case in the NGT it was revealed that the NTPC did not even cover coal wagons with tarpaulin on railways, decades after environmental clearances were granted in 1999, in CHH. In 2020, the SC passed an order directing for the wagons to be covered within a month’s time. 6. As of now, many environmental mediations remain glaringly haphazard. A plastic bag ban to succeed in one State requires a similar commitment from neighbouring States. A nation-wide intervention here, led by a Climate Commission, considering substitutes at scale for plastic-based products (which are derived from petroleum) and looking at both innovation and implementation, would be useful. A climate law could consider two aspects. * A ‘Commission on Climate Change’ could be set up, with the power and the authority to issue directions, and oversee implementation of plans and programmes on climate. The Commission could have quasi-judicial powers with powers of a civil court. It should be assisted by a technical committee * Second, we need a system of liability and accountability at short-, medium- and long-term levels as we face hazards. This also means having a legally enforceable National Climate Change Plan that goes beyond just policy guidelines. Are climate vagaries acts of god, or do certain actions exacerbate them? eg. in a 2016 order of NGT, te damage by 2013 UK floods was declared not an ‘Act of God’ and invoked the Principle of No Fault liability. The Alaknanda Hydro Power Company was asked by the Tribunal to pay more than ₹9 crore in damages.

* **Global E-waste Monitor** reported that 53.6 MT of waste electronic and electrical equipment were generated in 2019. * That represented a 21 per cent jump in the five years since 2014 (with e-waste predicted to reach 74 MT by 2030). * E-waste generation was increasing annually by 2 MT. * The rise is attributed to a higher consumption rate of electronics, shorter product lifecycles and limited repair options.

Answer 238

stats: * Acc to CPCB, India generated more than 10 lakh tonnes of e-waste in 2019-20, an increase from 7 lakh tonnes in 2017-18. Against this, the e-waste dismantling capacity has not been increased from 82 lakh tonnes since 2017-18. * In 2018, the Ministry of Environment had told the tribunal that 95% of e-waste in India is recycled by the informal sector and scrap dealers unscientifically dispose of it by burning or dissolving it in acids. **Efforts by India to manage e-waste:** Laws to manage e-waste have been in place in India since 2011, mandating that only authorised dismantlers and recyclers collect e-waste.

1. **15 of the top fossil fuel producing countries, including India, are not prepared to meet the requirements of** [**the 2015 Paris Climate Agreement**](https://www.insightsonindia.com/2021/01/26/what-are-the-implications-of-u-s-a-rejoining-the-paris-climate-agreement-the-u-s-administration-needs-to-do-much-more-than-just-rejoining-the-paris-agreement-analyze/). 2. Governments are in aggregate planning to produce 110 per cent more [**fossil fuels**](https://www.insightsonindia.com/2020/10/14/assess-implications-of-phasing-out-fossil-fuel-subsidies-on-the-mitigation-of-climate-change/) in 2030 than would be consistent with limiting global warming to 1.5°C, and 45 per cent more than would be consistent with limiting warming to 2°C, on a global level. 3. By 2040, this excess grows to 190% and 89%, respectively. 4. The 15 countries analysed as part of the report were responsible for 75 per cent of the world’s fossil fuel production in 2020. 5. India is the seventh-largest producer of fossil fuels among the 15 countries. **As part of the Paris Agreement,** India pledged a 33%–35% reduction in the “emissions intensity” of its economy by 2030, compared to 2005 levels. However, **as part of the Atmanirbhar Bharat campaign,** the government pledged to become a self-reliant producer of coal and made a plan to invest Rs 500 billion worth of infrastructure for coal extraction.

Answer 245

Held at Glasglow main task for COP26 was to finalise the rules and procedures for implementation of the Paris Agreement. Most of these rules had been finalized by 2018, but a few provisions, like the one relating to creation of new carbon markets, had remained unresolved. So many leaders have assembled on only two earlier occasions, at the climate meetings in Copenhagen in 2009 and Paris in 2015. On both those occasions, the COPs were aiming to deliver a major agreement. Copenhagen had failed in that, but Paris had succeeded. Glasgow did benefit from the presence as many of them also announced new and enhanced climate actions. However, the final agreement was a mixed bag.

Answer 246

1. Mitigation 2. Adaptation 3. Finance 4. Glasgow Agreement 5. Loss and Damage 6. Carbon Markets 7. Parallel discussions and announcements

Answer 247

Glasgow agreement has emphasised that stronger action in the current decade was most critical to achieving the 1.5-degree target. Accordingly, it has: 1. Asked countries to strengthen their 2030 climate action plans, or NDCs by next year 2. Established a work programme to urgently scale-up mitigation ambition and implementation 3. Decided to convene an annual meeting of ministers to raise ambition of 2030 climate actions 4. Called for an annual synthesis report on what countries were doing 5. Requested the UN Secretary General to convene a meeting of world leaders in 2023 to scale-up ambition of climate action 6. Asked countries to make efforts to ***_reduce usage of coal as a source of fuel, and abolish “inefficient” subsidies on fossil fuels._*** The initial language on this provision was much more direct. It called on all parties to accelerate phase-out of coal and fossil fuel subsidies. developing countries however got it changed to “*phase down unabated coal power and phase out inefficient fossil fuel subsidies while providing targeted support to the poorest and the most vulnerable in line with national circumstances*…”. Despite the dilution, the inclusion of language on reduction of coal power is being seen as a significant movement forward. 7. Has called for a phase-down of coal, and phase-out of fossil fuels. This is the first time that coal has been explicitly mentioned in any COP decision. It also led to big fracas at the end, with a group of countries led by India and China forcing an amendment to the word “phase-out” in relation to coal changed to “phase-down”.

Answer 248

1. Asked the developed countries to **_at least double the money being provided for adaptation by 2025 from the 2019 levels.**_ In 2019, about $15 billion was made available for adaptation that was less than 20 per cent of the total climate finance flows. _**Developing countries have been demanding that at least half of all climate finance should be directed towards adaptation efforts._** 2. Created a **_two-year work programme to define a global goal on adaptation._** The Paris Agreement has a global goal on mitigation — reduce greenhouse gas emissions deep enough to keep the temperature rise within 2 degree Celsius of pre-industrial times. A **similar global goal on adaptation has been missing**, primarily because of the difficulty in defining such a target. **Unlike mitigation efforts that bring global benefits, the benefits from adaptation are local or regional.** There are **no uniform global criteria against which adaptation targets can be set and measured**. However, this has been a long-pending demand of developing countries and the **Paris Agreement also asks for defining such a goal**

Answer 249

In 2009, developed countries had promised to mobilise at least $100 billion every year from 2020. This promise was reaffirmed during the Paris Agreement, which also asked the developed countries to scale up this amount from 2025. The 2020 deadline has long passed but the $100 billion promise has not been fulfilled. The developed nations have now said that they will arrange this amount by 2023.

Answer 250

A deal aimed at staving off dangerous climate change has been struck at the COP26 summit in Glasgow. The pact has: 1. Expressed “deep regrets” over the failure of the developed countries to deliver on their $100 billion promise. It has asked them to arrange this money urgently and in every year till 2025 2. Initiated discussions on setting the new target for climate finance, beyond $100 billion for the post-2025 period 3. Asked the developed countries to provide transparent information about the money they plan to provide

Answer 251

* The worst affected from the climate disasters are the poor and small countries, and the island states. There is no institutional mechanism to compensate these nations for the losses, or provide them help in the form of relief and rehabilitation. Paris Agreement is deeply flawed as it says loss and damage cannot be taken as compensation or liability. This needs to be reworked. * Introduced eight years ago in Warsaw, the provision hasn’t received much attention at the COPs, mainly because it was seen as an effort requiring huge sums of money. * Thanks to a push from many nations, substantive discussions on loss and damage could take place in Glasgow. One of the earlier drafts included a provision for setting up of a facility to coordinate loss and damage activities. * However, the final agreement, which has acknowledged the problem and dealt with the subject at substantial length, has only established a “dialogue” to discuss arrangements for funding of such activities. This is being seen as a major let-down. * The Glasgow deal did agree to fund the **_Santiago Network_**, a **body that aims to build technical expertise on dealing with loss and damage**, such as helping countries consider how to move communities away from threatened shorelines

Answer 252

A carbon market existed under Kyoto Protocol but is no longer there because the Protocol itself expired last year. A new market under Paris Agreement is yet to become functional. **_The resolution of the deadlock over carbon markets represents one of the major successes of COP26._** Developing countries like India, China or Brazil have large amounts of carbon credits left over because of the lack of demand as many countries abandoned their emission reduction targets. The developing countries wanted their unused carbon credits to be transitioned to the new market, something that the developed nations had been opposing on the grounds that the quality of these credits — the question whether these credits represent actual emission reductions — was a suspect. The Glasgow Pact has offered some reprieve to the developing nations. It has allowed these carbon credits to be used in meeting countries’ first NDC targets. These cannot be used for meeting targets in subsequent NDCs. That means, if a developed country wants to buy these credits to meet its own emission reduction targets, it can do so till 2025. Most countries have presented climate targets for 2025 in their first NDCs. 320 million Kyoto credits registered since 2013, each representing a tonne of CO₂, will be transferred to the Paris Agreement. The final deal agreed that a share of proceeds from each Carbon trade will go to developing countries for adaptation. This is mandatory in Article 6.4 (new centralised carbon market), but only set at 5 per cent. In Article 6.2 (bilateral trades), this share is voluntary. On double-counting, it has been decided that a country that generates a credit will decide whether to authorise it for sale to other nations or to count towards their climate targets.If authorised and sold, the seller country will add an emission unit to its national tally and the buyer country will deduct one, to ensure the emissions cut is counted only once between countries.

Answer 253

1. India announced a Panchamitra (a mixture of five elements) of climate actions. It raised the targets for two of its existing climate targets, announced two new ones, and also promised to turn net-zero by the year 2070. 2. Several other countries also announced enhanced climate actions. Brazil, for example, said it would advance its net-zero target year from 2060 to 2050. China promised to come out with a detailed roadmap for its commitment to let emissions peak in 2030, and also for its 2060 net-zero target. Israel announced a net zero target for 2050. 3. Over 100 countries pledged to reduce methane emissions by at least 30 per cent from present levels by 2030. This pledge, if achieved, is estimated to avoid about 0.2 degree Celsius temperature rise by the middle of the century. The methane pledge is being seen as one of the biggest successes at COP26. 4. 105 countries accounting for 85 per cent of the planet’s forests signed the Glasgow Leaders’ Declaration on Forests and Land Use. The Declaration commits the countries to “halt and reverse deforestation and land degradation by 2030”. 5. Over 30 countries signed on to a declaration promising to work towards a transition to 100 per cent zero-emission cars by the year 2040

Answer 254

Forests absorb around a third of the global carbon dioxide released from burning fossil fuels every year. Currently, 23 per cent of global emissions come from land use activities such as logging, deforestation and farming. on average, annual tropical tree cover loss between 2014 and 2018 emitted 4.7 gigatons of carbon dioxide per year — more than all of EU’s 2017 greenhouse gases emissions But we are losing them at the rate of an area equivalent to the size of 27 football pitches every minute. Global Forest Watch reported that the world lost roughly 25.9 million hectares (nearly 100,000 square miles) of tree cover (an area roughly the size of Colorado) to deforestation in 2020 — much of it in the tropics. Article 5 of the Paris Agreement signed in 2015 mandates parties to “reduce emissions from deforestation and forest degradation” by taking up forest conservation and protection. At the Glasgow Summit, 105 countries accounting for 85 per cent of the planet’s forests signed the Glasgow Leaders’ Declaration on Forests and Land Use. The Declaration commits the countries to “halt and reverse deforestation and land degradation by 2030”. Signatories to the declaration include countries that are responsible for deforestation as well as consumers of commodities that lead to forest clearance like Brazil, China, EU, Russia and the United States. 28 countries that represent 75 per cent of global trade in key commodities responsible for causing deforestation signed a new Forests, Agriculture and Commodity Trade (FACT) Statement “to deliver sustainable trade and reduce pressure on forests, including support for smallholder farmers and improving the transparency of supply chains”. As a follow up, 30 financial institutions that have an asset worth more than $8.7 trillion also agreed to “eliminate” investment in commodity-driven deforestation. Brazil, Russia and China, who did not sign the 2014 NY Declaration for Forests (that agreed to reduce deforestation by 50% by 2020 and end it by 2030 AND restoration of 150 million hectares of degraded landscapes and forestlands by 2020 and 350 million hectares by 2030) have signed the Glasgow declaration as well. Skepticism over implementation: Failure of NY Declaration for Forests- Instead, going by a five-year assessment of this pledge, the global rate of gross tree cover loss increased by 43 per cent in 2019.

Answer 255

1. Pact’s fundamental and fatal flaw is in the very first page: “it notes the importance *for some* of the concept of climate justice” 2. Rapid assessments by four different groups — United Nations Environment Programme, IEA, Climate Action Tracker and Climate Resource — have found that even if the 2030 NDCs are achieved, the world will be on track for 2.4^oC of warming. 3. Climate Justice: 1. US, EU-27, UK Canada, Australia, Japan and Russia and joined now by China — have consumed roughly 70 per cent of the carbon budget, the space in the atmosphere that is available to keep the world below the 1.5°C temperature rise. 2. About 70 per cent of the world’s population needs access to carbon space for development; they cannot be told not to develop. 3. Against the CBDR principle, poor nations with minuscule per capita carbon footprint are asked to constrain their developmental health in trying to abide by the Paris Agreement. India’s Net Zero goal of 2070 was criticised even though it is in line with CBDR. 4. an upwardly increasing climate finance goal was not agreed upon. flow of real money is still illusionary; only Germany, Norway and Sweden are paying their share. 5. Major developed countries, which are big polluters, did not commit to domestic fossil fuel phase-out, only to halt funding it internationally. 6. Loss and damage finance was also not announced. The CoP just decided to establish a dialogue 7. China has not been given any carbon dioxide (CO₂) reduction targets, despite being the world’s largest emitter. It will take up 33 per cent of the remaining carbon budget for this decade. While it says it will not build coal-fired power projects abroad, it is silent about such plants at home. India needs to be de-hyphenated from China; China needs to be de-hyphenated from G-77 8. Human rights have been mentioned in the text, and any grievances by affected communities will be addressed by an independent body. However, indigenous peoples’ right to free, prior and informed consent has not been outlined. 9. No pledge has been made to deliver 50 per cent of climate finance for adaptation.

Answer 256

IPCC, in its latest assessment report, specially mentioned for the first time short-lived climate pollutants like methane needs to be targeted for reducing global warming. It said that methane mitigation has the greatest potential to slow warming over the next 20 years. Methane’s presence in the atmosphere is just 2 parts per million (PPM) compared to 412 PPM for carbon dioxide (CO2). Its life in the atmosphere is hardly 12 years compared to more than 200 years of CO2. But, methane traps heat 84 times that of CO2, thus making it a ‘super warmer of the atmosphere’. Among GHGs, it is the second-biggest contributor to global warming after CO2, according to IPCC. At least 30 per cent of global warming since the industrial revolution is due to methane emissions, according to UNEP. At present, it is proliferating faster than any other time since record keeping began in the 1980s.

Answer 257

● Most human-caused methane emissions came from three sectors: Fossil fuels, waste and agriculture. ● Oil and gas extraction, processing and distribution accounted for 23 per cent of methane emissions in the fossil fuel sector. Coal mining accounted for 12 per cent of emissions. ● Landfills and wastewater made up about 20 per cent of emissions in the waste sector. In the agricultural sector, livestock emissions from manure and enteric fermentation constituted for roughly 32 per cent and rice cultivation eight per cent of emissions.

Answer 258

COP26 the first one in recent history to dedicate an event on it. 105 countries led by the United States and the European Union (US ad EU were the first ones to sign it) signed the **voluntary and non-binding** Global Methane Pledge. Under this, countries have promised to cut their methane emissions by at least **30 per cent by 2030**. if this level is achieved, it will amount to a 40 per cent cut in the global methane emissions. Among other deals, this pledge has the most immediate impact on reducing GW. Warming can be reduced by at least 0.2 degrees Celsius (°C) by 2050, if countries deliver according to the pledge The signatories include **15 major methane emitters** such as Brazil, Nigeria and Canada. But the **three biggest emitters — China, Russia and India, together contributing 35 per cent of the global methane emissions — didn’t sign the pledge.** With existing technology, a 75 per cent reduction in methane from the oil and gas sector is possible, 50 per cent of this could be done at no net cost. The assessment showed that up to 80 per cent of measures necessary to stop methane leaks from oil and gas operations and 98 per cent from coal don’t involve any cost. Rather, the steps will increase earnings as the saved methane can be sold.

Answer 259

India's 5 Commitments- *Panchamrit-* India's Gift to the World 1. Net Zero emission by 2070 2. By 2030 non-fossil fuel generation to increase to 500GW (target of 450GW committed in 2015 Paris agreement) 3. By 2030, 50% of installed capacity to be of RE 4. Carbon emissions to be reduced by 1BnTonne. According to world resources Institute, India's total Greenhouse gas emissions were about 3.3 billion tons in 2018 and is projected to rise above 4 billion tonnes per year by 2030. Thus, India could be emitting 35 to 40 billion tonnes GHG at the current rate of growth. Cutting 1 billion Tonne would represent a reduction of 2.5 to 3% in its absolute emission 5. 45% reduction in Carbon intensity (increased from 33-35% commitment in 2015) Further, * Indian Railways was committed to a target of net zero emission by 2030 * Proposed a LIFE movement i.e. Lifestyle for Environment.

Answer 260

target prescribed for emission reduction by 2012 from 1990 levels under First commitment period of Kyoto Protocol vs actual USA: -7% vs +0.13% Japan: -6% vs +13% CAnada: -6% vs +24.5%

Answer 261

World' top Gross emitters: China (~22%; 11.5 BnT)→ USA (~11%; 5BnT)→ EU (3.3BnT)→ India (2.6BnT)→ Russia (1.8BnT) Percapita emission: USA (15.5T);Russia (12.5T); China (8.1 T); EU (6.5 T); India (1.9 T)

Answer 262

1. F; Water vapour 2. F; Nitrous oxide concentrations in the atmosphere are currently 319 ppb, 18 percent higher than what they were prior to the Industrial Revolution.

Answer 263

Net-zero, which is also referred to as carbon-neutrality, **is a state in which a country’s emissions are compensated by absorption and removal of greenhouse gases from the atmosphere i.e.** human activities result in no net effect on the climate system. This will also involve accounting for regional or local bio-geophysical effects of human activities that affect local climate or surface albedo * Absorption of the emissions can be increased by creating more carbon sinks such as forests, while removal of gases from the atmosphere requires futuristic technologies such as carbon capture and storage. It is being argued that global carbon neutrality by 2050 is the only way to achieve **the Paris Agreement target of 2deg C** **Many countries have already committed in some form or another (Refer Fig)**

Answer 264

1. The IPCC 1.5°C report notes that effectiveness of techniques and technologies to remove CO2 from the air remains unproven at scale, and some may even carry significant risks for sustainable development. 2. once we stop emitting GHGs from fossil fuels, we still need to offset the emissions already liberated in the atmosphere over the years. That is the difference between zero and net zero. On its own, just reaching net zero in 2050 is not enough to meet the goal of limiting global warming to 1.5ºC. What will be required—at a planetary scale—is to reduce emissions by 7.6 per cent every year, between 2020 and 2030. 3. net zero is also intrinsically inequitable. Big polluters are setting net zero targets of 2050 for themselves. if the world needs to be net zero by 2050, then these countries needed to have already turned net zero or do so by 2030. 4. there is no substance in the net zero target that countries have declared. It is but an aspirational idea—something that they will work towards. Practically all the countries that have made the grandstanding declaration have no plans on how they will get to net zero. Countries have failed to meet their commitments in past climate deals as well. 5. Further, India argues that countries clamouring for net zero will continue to pollute on a per capita basis way beyond their fair share

Answer 265

Achieving ‘net zero’ means deep and significant **cuts to fossil fuel use** that could affect the development trajectory of India 1. For India to achieve a net-zero target by 2070, usage of coal especially for power generation would need to peak by 2040 and drop by 99% between 2040 and 2060. 2. And, the consumption of crude oil across sectors would also need to peak by 2050 and fall substantially by 90% between 2050 and 2070.

1) almost every yr, since Rio summit, has seen higher CO2 emissions than the previous yr 2) 50% of all CO2 humans hv put into atm since IR was added after 1990 3) 43 Bn T of CO2 added this yr

Answer 268

IPCC estimates that for target 1.5C , we will need to capture and store around 730 Bn T CO2 emissions by 2100. 1) not enough, will require planting trees worth a small continent 2) developed country won't compromise and may lease land in poor ones. Thus afforestation is needed in consonance with other developmental needs.

Answer 269

1. The **increase in CO2 from 2019 to 2020 was slightly lower than that observed from 2018 to 2019** but higher than the average annual growth rate over the past decade. 2. This is despite the approximately 5.6% drop in fossil fuel CO2 emissions in 2020 due to restrictions related to the pandemic. 3. **For methane,** the increase from 2019 to 2020 was higher than that observed from 2018 to 2019 and also higher than the average annual growth rate over the past decade. 4. **For nitrous oxides,** the increase was higher and also than the average annual growth rate over the past 10 years. 5. **Concentration of carbon dioxide (CO2),** the most significant greenhouse gas, reached 413.2 parts per million in 2020 and is 149% of the pre-industrial level. Methane (CH4) is 262% and nitrous oxide (N2O) is 123% of the levels in 1,750 when human activities started disrupting earth’s natural equilibrium. 6. Roughly **half of the CO2 emitted by human activities today remains in the atmosphere.** The other half is taken up by oceans and land ecosystems. 7. From 1990 to 2020, radiative forcing — the warming effect on our climate — by long-lived greenhouse gases increased by 47%, with CO2 accounting for about 80% of this increase.

SC's judgement of 2018, banned the sale and production of firecrackers in Delhi-NCR and regulated the use of firecrackers across the country. crackers couldn’t be loud beyond a certain limit, had to be approved by the **Petroleum and Explosives Safety Organisation (PESO)** and had to be free of mercury, arsenic and barium. Online sale of firecrackers has been completely banned. In 2021, while setting aside the judgement of WBHC, SC said **a blanket ban on firecrackers may not be possible. Instead there is need to** * **strengthen the mechanism to stop misuse** * Measures ought to be in place to prevent the use of toxic chemicals in firecrackers. * SC cannot infringe the right to life of other citizens “under the guise of employment of few” while considering a ban on firecrackers.. Have to strike a balance between employment, unemployment and right to life.

Answer 276

many studies show, the burning of firecrackers is an unusual and peak source of pollution, made up of particles and gases. * One study in Milan, Italy, quantified the increase in the levels of several elements in the air in one hour as 120 times for Strontium, 22 times for Magnesium, 12 times for Barium, 11 times for Potassium and six times for Copper. * The [**Central Pollution Control Board**](https://www.insightsonindia.com/tag/about-the-central-pollution-control-board/) conducted a study in Delhi in 2016, and found that the levels of Aluminium, Barium, Potassium, Sulphur, Iron and Strontium rose sharply on Deepavali night, from low to extremely high. * Similar episodic spikes have been recorded in China and the U.K. Pollution from firecrackers affects the health of people and animals, and aggravates the already poor ambient air quality in Indian cities.

* Ganga provides water to about 40% of [India's population](https://en.wikipedia.org/wiki/Demographics_of_India) across 11 [_states_](https://en.wikipedia.org/wiki/States_of_India) * Today, the Ganges is considered to be the fifth-most polluted river in the world * The river flows through 100 cities with populations over 100,000. A large proportion of sewage water often goes untreated into Ganga * Industrial waste: Industrial effluents are about 12% of the total volume of effluent reaching the Ganges. Although a relatively low proportion, they are a cause for major concern because they are often toxic and non-biodegradable. Plastic and industrial waste, such as wastewater from the Factories that sit on the banks of the Ganga, is another cause of pollution. * The most worrying problem facing the river is its increasing lack of water. The water level in the river is going down at an unprecedented rate. Also if the flow in the river is maintained it can solve the problem of 60-80 per cent of organic pollutants and we may not require such an elaborate programme. Acc to a paper by IIT-Kharagpur, the baseflow amount of the river has decreased by 56 per cent in 2016 as compared to the 1970s. * A 2006 measurement of pollution in the Ganges revealed that river water monitoring over the previous 12 years had demonstrated [fecal coliform](https://en.wikipedia.org/wiki/Fecal_coliform) counts up to 100,000,000 MPN (most probable number) per 100 ml and [biological oxygen demand](https://en.wikipedia.org/wiki/Biological_oxygen_demand) levels averaging over 40 mg/l in the most polluted part of the river in Varanasi. The overall rate of water-borne/enteric disease incidence, including acute gastrointestinal disease, was estimated to be about 66%

* Sewage Treatment: * As per Namami Gange targets, STPs with over 2,000 million litres a day (MLD) capacity had to be rehabilitated of which only 328 MLD have been done. * Till August 31, 2018 a total of 236 projects, including STPS, had been sanctioned out of which only 63 had been completed. Only 19% of sanctioned fund has been spent * new projects are delayed because land acquisition and other delays * even the ones functional are not working optimally. While many fail to meet the qlty parameters of discharge water, theyare aso unable to get the total amount of influents, primarily due to lack of sewerage network in the cities like Kanpur. A total network of 2,071 km of new sewer line projects was sanctioned after Namami Gange came into being but only 66.85 km has been laid. * Flow Restoration: According to a report published by Wildlife Institute of India in May 2018, 16 existing, 14 ongoing and 14 proposed hydroelectric projects on the Bhagirathi and Alaknanda river basins have turned the upper stretch of the Ganga “ecological deserts”. * Sludge control: * A staggering 99.93 per cent villages lying on the banks of Ganga, also known as Ganga Grams, have been declared ODF but the level of coliform in Ganga water has not reduced as expected. while toilets were constructed, hardly a thought was given to management of sludge. According to a study conducted by CSE, most of the cities surveyed had twin-pit technology which is not recommended in low-lying areas. * Against the standard of 2,500 per 100 ml, the faecal coliform ranged from 2,500 to 2,40,000 per 100 ml in the Ganga basin cities in May 2018 * aecal sludge is a bigger pollutant than sewerage. While the BOD of sewage is 150-300 mg/l, that of faecal sludge would be 15,000-30,000 mg/l.

Potential: ● As reported by Reuters, the mine would have produced **enough lithium to operate one million electric vehicles** along with boric acid and sodium sulphate. ● When fully functional, the mine would have created “58,000 tonnes of refined battery-grade lithium carbonate” every year, which would have made it Europe’s most lithium-producing mine. What's the concern? * While the country has already been ridden with industrial pollution, a new mine would only make it worse, polluting the land and water in the area. * Serbia has ranked as Europe’s fifth and the world’s 32nd most polluted country in a list of 98 countries. * According to a 2019 report by Global Alliance on Health and Pollution, Serbia is one of the top ten countries with the most deaths due to pollution — 175 deaths per 100,000.

Answer 285

UNEP defined POP as “chemical substances that persist in the environment, bio-accumulate through the food web, and pose a risk of causing adverse effects to human health and the environment” Uniqueness of POPs: ● POPs are lipophilic, which means that they accumulate in the fatty tissue of living animals and human beings. ● In fatty tissue, the concentrations can become magnified by up to 70 000 times higher than the background levels. ● As you move up the food chain, concentrations of POPs tend to increase so that animals at the top of the food chain such as fish, predatory birds, mammals, and humans tend to have the greatest concentrations of these chemicals. Exposure to POPs can lead to cancer, damage to central & peripheral nervous systems, diseases of immune system, reproductive disorders and interference with normal infant and child development. Stockholm Convention (covered in f/c Indian Geog) Sources of POPs: ● Improper use and/or disposal of agrochemicals and industrial chemicals. ● Elevated temperatures and combustion processes. ● Unwanted by-products of industrial processes or combustion.

Answer 286

India and Russia have blocked a proposal that would have allowed the UN Security Council to deliberate on climate-related issues. The draft resolution, piloted by Ireland and Niger, sought to create a formal space in the Security Council for discussions on climate change and its implications on international security. ● It also asked that the UN Secretary-General provide periodic reports on how risks from climate change can be addressed to prevent conflicts. What has India said? India is second to none when it comes to climate action and climate justice. But UNSC is not the place to discuss either issue. In fact, an attempt to do so appears to be motivated by a desire to evade responsibility in the appropriate forum and divert the world’s attention from an unwillingness to deliver where it counts. Concerns over the proposal: ● Billing climate change as a threat to international security diverts the council’s attention from genuine, deep-rooted reasons of conflict in the countries on the Council’s agenda. ● Securitising climate change would be largely convenient to countries that were actively helping engender conflicts or waged military activities in diversion from the Security Council’s mandate or simply don’t want to provide the necessary help to developing countries. ● Action taken as part of the resolution can potentially range from sanctions on fossil-rich countries to UN military intervention in domestic conflicts perceived to have been caused by climate change.

Answer 297

* A site may be added to the [List of World Heritage in Danger](https://en.wikipedia.org/wiki/List_of_World_Heritage_in_Danger) if conditions threaten the characteristics for which the landmark or area was inscribed on the World Heritage List. * Such problems may involve armed conflict and war, natural disasters, pollution, poaching, or uncontrolled urbanisation or human development. * This danger list is intended to increase international awareness of the threats and to encourage counteractive measures. * Threats to a site can be either proven imminent threats or potential dangers that could have adverse effects on a site * The state of conservation for each site on the danger list is reviewed yearly; after this, the Committee may request additional measures, delete the property from the list if the threats have ceased or consider deletion from both the List of World Heritage in Danger and the World Heritage List * Only three sites have ever been [delisted](https://en.wikipedia.org/wiki/Former_UNESCO_World_Heritage_sites) from both the lists: * the [Arabian Oryx Sanctuary](https://en.wikipedia.org/wiki/Arabian_Oryx_Sanctuary) in Oman, * the [Dresden Elbe Valley](https://en.wikipedia.org/wiki/Dresden_Elbe_Valley) in Germany, and * the [Liverpool Maritime Mercantile City](https://en.wikipedia.org/wiki/Liverpool_Maritime_Mercantile_City) in the United Kingdom * [Manas Wildlife Sanctuary](https://en.wikipedia.org/wiki/Manas_Wildlife_Sanctuary) was listed in [UNESCO's List of World Heritage in Danger](https://en.wikipedia.org/wiki/List_of_World_Heritage_in_Danger) in 1992, but was removed in 2011 following significant improvements. [Hampi](https://en.wikipedia.org/wiki/Group_of_Monuments_at_Hampi) was added to the List of World Heritage Sites in Danger in 1999, but got removed in 2006 following successful conservation efforts.

Answer 298

The first global assessment to quantitatively measure threats to Natural World Heritage Sites found that 63 per cent of sites have been damaged by increasing human pressures including encroaching roads, agriculture infrastructure and settlements over the last two decades Of the Natural World Heritage Sites that contain forest, 91 per cent experienced some loss since 2000. Many of them are more threatened than previously thought and require immediate conservation action perceived under-representation of heritage sites outside Europe, disputed decisions on site selection and adverse impact of mass tourism on sites unable to manage rapid growth in visitor numbers A large [lobbying industry](https://en.wikipedia.org/wiki/Lobbying) has grown around the awards, because World Heritage listing can significantly increase tourism returns. Site listing bids are often lengthy and costly, putting poorer countries at a disadvantage. Eritrea's efforts to promote [Asmara](https://en.wikipedia.org/wiki/Asmara) are one example. Further, In 2021, international scientists recommended UNESCO to put the Great Barrier Reef on the endangered list. the Australian government campaigned against this, and in July 2021, the [World Heritage Committee](https://en.wikipedia.org/wiki/World_Heritage_Committee), made up diplomatic representatives of 21 countries, ignored UNESCO's assessment, based on studies of scientists

The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) is an independent intergovernmental body, established by member States in 2012. **Objective of IPBES:** Strengthen the science-policy interface for biodiversity and ecosystem services for the conservation and sustainable use of biodiversity Findings: 1. Less than 25% of earth's land surface area remains free from substantial human impacts. 2. up to 1 million of the estimated 8 million plant and animal species on Earth are at risk of extinction within decades. 3. 5 L plants and animal currently have ‘insufficient habitat for long term survival’ 4. 40% of amphibian species are threatened with extinction, along with 33% of reef forming corals and 33% of marine mammals 5. **Loss of pollinators:** Up to $577 billion in annual global crops are at risk from pollinator loss. Insect pollinators are unfortunately an excellent example of the problems caused by human activities."There's a newly coined phrase for insect declines — the **'windshield effect’**. 1. the windscreen phenomenon is a term given to the anecdotal observation that people tend to find **fewer insects smashed on the windscreens** of their cars now compared to a decade or several decades ago. This effect has been ascribed to major global declines in insect abundance. 6. The report identified a **range of risks,** from the **disappearance of insects** vital for pollinating food crops, to the **destruction of coral reefs** that support fish populations that sustain coastal communities, or the **loss of medicinal plants**. 7. 75% of the land environment and 66% of the marine environment impacted due to anthropogenic activities. 8.

Climate risk 1. business as usual is predicted to warm earth by 4.3deg C, thta will wipe out 1/6th of all species 2. Even if Paris targets NDCs are achieved, a 2 Deg C rise in temp will wipe out 5% of earth species. 10. **Pollution and waste** 1. Plastic pollution has increased tenfold since 1980. 2. 300-400 million tons of heavy metals, solvents, toxic sludge and other industrial waste are dumped into the world's water systems.

Answer 335

1. The Bill seeks to reduce the pressure on wild medicinal plants by encouraging the cultivation of medicinal plants. 2. The Bill proposes to exempt AYUSH practitioners from intimating biodiversity boards for accessing biological resources or knowledge. 3. The Bill also facilitates fast-tracking of research, simplify the patent application process, decriminalises certain offences. 4. The Bill brings more foreign investments in biological resources, research, patent and commercial utilisation, without compromising the national interest. 5. The bill focuses on regulating who can access biological resources and knowledge and how access will be monitored. 6. The Bill has also clarified and strengthened the role of state biodiversity boards.

Answer 336

● The main focus of the bill is to facilitate trade in biodiversity as opposed to conservation, protection of biodiversity and knowledge of the local communities. ● The bill has been introduced without seeking public comments as required under the pre-legislative consultative policy. ● There are ambiguous provisions in the proposed amendment to protect, conserve or increase the stake of local communities in the sustainable use and conservation of biodiversity. ● Activists say that the amendments were done to “solely benefit” the AYUSH Ministry. ● The bill has excluded the term Bio-utilization which is an important element in the Act. Leaving out bio utilization would leave out an array of activities like characterization, incentivisation and bioassay which are undertaken with commercial motive. ● The bill also exempts cultivated medicinal plants from the purview of the Act but it is practically impossible to detect which plants are cultivated and which are from the wild.

carried out every 4 yrs 2018 census was carried out using doubling sample technique. Further, a new digital Tiger census technique was used and an Android application- **Monitoring system for tigers intensive protection and ecological status (M-STrIPES)** was introduced It is the first time Bhutan Bangladesh and Nepal are part of India's Tiger census to jointly estimate the number of tigers in the region of shared border areas 1. The total count of tigers has risen to 2,967 in 2018 (70% of global pop) from 2,226 in 2014 — an increase of 33% in four years. and 100% since 2006 2. **Tiger population** within reserves is 1,923 (65% of the total tiger population of India) which means 35% of the tiger population still lives outside the reserves. 3. **State wise:** Madhya Pradesh has maximum tigers at 526 followed by Karnataka at 524 (KN was 1st since 2010) and 442 in Uttarakhand. 1. ***Kanha Tiger Reserve in Madhya Pradesh is the first tiger reserve in India to officially introduce a mascot, Bhoorsingh the Barasingha*** 4. **Chhattisgarh, Odisha** and Mizoram(**0 tiger spotted**) saw a decline in the tiger population and all other States saw a positive increase. 5. **Highest Tiger Reserves:** Corbett Tiger Reserve(Uttarakhand) has the highest tigers followed by Nagarhole tiger reserve(Karnataka) and Bandipur Tiger Reserve(Karnataka). 6. **Dampa** Tiger Reserve(Mizoram), Buxa Tiger Reserve(West Bengal) and Palamau Reserve(Jharkhand) have no tigers left. 7. 2018 tiger census divided tiger habitats in India into five tiger landscapes 1. Shivalik Gangetic plains 2. Central India and Eastern Ghats- 1033 tiger 3. WG- 933 tigers 4. NE Hills and Brahmputra flood plains 5. Sunderbans 8. Kerala had the highest increase in tiger pop (by 313%) followed by TN and Bihar

Answer 349

● In Terai and Shivalik hills habitat — Corbett tiger reserve, for example — 10-16 tigers can survive in 100 sq km. ● This comes down to 7-11 tigers per 100 sq km in the reserves of north-central Western Ghats such as Bandipur. ● According to the 2018 All-India Tiger report, the carrying capacity in the Sunderbans is at around 4 tigers per 100 sq km. Factors that determine tiger density: ● Availability of food and space. ● Tolerance levels exhibited by the locals who live around them to policymakers who decide management strategies.

1. Overall, conservative estimates of **2,359 tigers were seized from 2000 to 2018 across 32 countries** and territories globally. 2. On average, **60 seizures were recorded annually**, accounting for almost 124 tigers seized each year. 3. The **top three countries with the highest number of seizure incidents** were **India** (463 or 40.5% of total seizures) and **China** (126 or 11.0%), closely followed by **Indonesia** (119 or 10.5%). 4. In terms of various body parts seized, **India had the highest share among countries for tiger skins (38%), bones (28%) and claws and teeth** (42%).

Answer 351

1) Generally experts follow popular "source and sink" population theory of a decad ago i.e. beyond the protected core tiger areas (source pop), a dispersing tiger pop was bound to be a sink pop and not guaranteed to survive. 2) Tiger T1C1 (travelled 1300km over 6 months) as well as growing no. of tigers in non-protected forests like Brahmpuri in chandrapur district shows a rethink needed.

Answer 352

● India has achieved the remarkable feat of doubling the tiger population in 2018 itself, 4 years ahead of the targeted year 2022. ● The model of success of India’s tiger governance is now being replicated for other wildlife like the Lion, Dolphin, Leopard, Snow Leopard and other small wild cats. ● The budgetary allocation for tiger conservation has increased from Rs 185 crore in 2014 to Rs 300 crore in 2022. ● 14 Tiger Reserves in India have already been awarded with international CA|TS accreditation and efforts are on to bring in more Tiger Reserves under CA|TS accreditation. * Conservation Assured | Tiger Standards (CA|TS) has been agreed upon as an accreditation tool by the global coalition of Tiger Range Countries (TRCs) and has been developed by tiger and protected area experts. * CA|TS is a set of criteria which allows tiger sites to check if their management will lead to successful tiger conservation * officially launched in 2013 * The Global Tiger Forum (GTF) and World Wildlife Fund India are the two implementing partners of the National Tiger Conservation Authority for CATS assessment in India. ● Approximately 4.3 million man-days of employment are being generated by 51 Tiger Reserves in India and funds from Compensatory Afforestation Fund Management and Planning Authority (CAMPA) are being utilized for promoting voluntary village resettlement from core areas of the Tiger Reserves. ● India is one of the Founding members of the intergovernmental platform of Tiger Range Countries – Global Tiger Forum, and over the years, GTF has expanded its programme on multiple thematic areas, while working closely with the Government of India, tiger states in India and tiger range countries. ○ Global Tiger forum is the only intergovernmental international body established with members from willing countries to embark on a global campaign to protect the tiger. Two legal instruments that have enabled tiger recoveries in India are: 1. The Wildlife Protection Act of 1972. 2. The Forest (Conservation) Act of 1980, which reinforced Project Tiger.

Answer 353

1. The National Tiger Conservation Authority (NTCA) has launched the M-STrIPES (Monitoring System for Tigers – Intensive Protection and Ecological Status), a mobile monitoring system for forest guards. 2. At the Petersburg Tiger Summit in 2010, leaders of 13 tiger range countries resolved to do more for the tiger and embarked on efforts to double its number in the wild, with a popular slogan ‘T X 2’. 3. The Global Tiger Initiative (GTI) program of the World Bank, using its presence and convening ability, brought global partners together to strengthen the tiger agenda. 4. Over the years, the initiative has institutionalised itself as a separate entity in the form of the Global Tiger Initiative Council (GTIC), with its two arms –the Global Tiger Forum and the Global Snow Leopard Ecosystem Protection Program. 5. The Project Tiger, launched way back in 1973, has grown to more than 50 reserves amounting to almost 2.2% of the country’s geographical area.

1. ESZs are transition zones from areas of high protection to areas involving lesser protection 2. They are notified and regulated under Environment protection Act 1986. 1. The act empowers the central government to take all measures that it feels necessary for protecting and improving the quality of the environment and to prevent and control environmental pollution 2. It allows for restrictions of areas in which certain developmental activities can be prohibited 3. History: 1. Recommended by committee like Pranab Sen committee 2000, Mohan Ram committee 2001 2. National wildlife Action Plan (2002-16) 2002 guidelines suggested lands within 10 km of the boundaries of national parks and sanctuaries should be notified as Eco fragile zone under Environment protection Act. These were aimed to serve as shock absorber for protected areas. But this caused problems for protected areas in urban areas 3. National Board of wildlife 2005 directions suggested that the delineation of ESZ would have to be side specific and should regulate rather than prohibit specific activities. 4. Supreme Court passed a judgement in 2006 directing all the states to demarcate ESZs extending up to 10 km from the protected areas, giving due regard to the precautionary principle. 5. MoEFCC 2019 notification: 1. Over 30% of India's protected area has been covered under ESZ 2. Out of 651 protected areas in India, is 316 are covered under the final notification; 100 is in A&N islands 3.

* The IBA programme of Birdlife International aims to identify, monitor and protect a global network of IBAs. The IBAs serve as conservation areas for protection of birds at the global, regional or sub-regional level. * According to Birdlife International, designation of IBAs is based on standardized criteria, namely * hold significant numbers of one or more globally threatened bird species, * be one of a set of sites that together hold a suite of restricted-range species or biome-restricted species and * have exceptionally large numbers of migratory or congregatory birds. * The Bombay Natural History Society and Birdlife International have identified 467 IBAs in India. Forty percent of these IBAs fall outside the PA network and thus form an important tool for landscape-level conservation planning.

Answer 363

Key Biodiversity Areas (KBAs) are nationally identified sites of global significance. KBAs are identified at the national, sub-national or regional level by local stakeholders using the two globally standard criteria of vulnerability and irreplaceability. Vulnerability: This criterion is triggered when there is a regular occurrence of significant (exceeding a threshold) population of a globally threatened species (according to the IUCN Red List) at the site. Currently proposed thresholds comprise presence of a single individual of a Critically Endangered or Endangered species, or 30 individuals of a Vulnerable species. Irreplaceability: This criterion refers to a site which is irreplaceable as it holds a significant proportion of a species’ global population at any stage of the species’ lifecycle. KBAs extend the Important Bird and Biodiversity Area (IBA) concept to other taxonomic groups. Examples include Important Plant Areas (IPAs) (Anderson 2002, Plantlife International 2004), Prime Butterfly Areas (van Swaay and Warren 2003), Important Mammal Areas (Linzey 2002) etc. Currently one of the many uses of KBAs is to help governments and communities achieve the 2020 Aichi Biodiversity Targets, especially targets 11 and 12 that focus on expanding the protected area network and preventing extinction of all known threatened species.

A flyway is a geographical region within which a single or a group of migratory species completes its annual cycle – breeding, moulting, staging and non-breeding. * Central Asian Flyway (CAF), is one of 9 key flight paths taken by migratory water birds. It **covers a large area of Eurasia between the Arctic and Indian Oceans.** * **Including India, there are 30 countries** under the Central Asian Flyway. * The CAF comprises several important migration routes of waterbirds, most of which extend from the northernmost breeding grounds in Siberia to the southernmost non-breeding wintering grounds in West Asia, India, the Maldives and the British Indian Ocean Territory.

Answer 368

* Approximately one in five of the world’s 11,000 bird species migrate, some covering enormous distances. Conserving migratory birds requires cooperation and coordination along the entire flyway between countries and across national boundaries. * Safeguarding flyways means protecting the birds from poachers, rejuvenating wetlands among others. Saving the wetlands, terrestrial habitats help in fulfilling the bigger purpose of saving an ecosystem. INdia launched a National Action Plan (NAP) 2018-2023 for conservtaion of migratory birds along Central Asian Flyway.

1. ISFR is a **biennial** publication of Forest Survey of India (**FSI**), an organization under **MoEFCC** 2. **First State of Forest Report published by FSI in 1988** 3. ISFR assesses the **forest and tree cover, bamboo resources, carbon stock and forest fires** 4. **Uniqueness**: 1. 2019 report for the first time has assessed the **qualitative nature of the forest cover**, including listing its **biodiversity** and the **type of plants and trees found.** 2. It also created a **national forest inventory** for the first time on **produce** from forests. * Dependence of fuelwood on forests is the highest in the State of Maharashtra, whereas, for fodder, small timber and bamboo, dependence is highest in Madhya Pradesh. 5. The analysis reveals that **21.40% of the forest cover of the country is highly to extremely fire prone.**

Answer 378

1. In the present ISFR 2021, FSI has included a new chapter related to **the assessment of forest cover in the Tiger Reserves, Corridors and Lion conservation area of India.** 2. A new initiative of FSI has also been documented in the form of a chapter, where **the ‘Above Ground Biomass’** has been estimated. FSI, in collaboration with Space Application Centre (SAC), ISRO, Ahmedabad, initiated a special study for estimation of Above Ground Biomass (AGB) at pan-India level, using L- band of **Synthetic Aperture Radar (SAR) data.** 3. FSI in collaboration of with Birla Institute of Technology & Science (BITS) Pilani, Goa Campus has performed a study based on **‘Mapping of Climate Change Hotspots in Indian Forests’.** The collaborative study was carried out with the objective to map the climatic hotspots over the forest cover in India, using computer model-based projection of temperature and rainfall data, for the three future time periods i.e. year 2030, 2050 and 2085. 4. **The report also contains information on various parameters State/UT wise.** Special thematic information on forest cover such as hill, tribal districts, and north eastern region has also been given separately in the report.

Answer 379

1. shows a minimal increase of 0.16 million ha (0.2 per cent) in the forest cover between 2019 and 2021. India's forest cover stood at **71.38 Mn Ha** in 2021 (22% of INdia's geographical area) as compared to 71.22 Mn Ha in 2019 2. The quality of forests also seems to have been stable. 1. very dense forest: increased marginally to 9.98 Mn Ha (3% of India's area) and now constitute just 14% of foerst cover 2. moderately dense forest decreased marginally to 30.68 Mn Ha (9%of INdia's area) 3. Open forest increased marginally to 30.7 Mn Ha (9%of INdia's area) 4. There is, in fact, some increase in the “very dense” forest category (with canopy cover of over 70 per cent) and in the “open” forest category (canopy cover 10-40 per cent), and 5. almost an equal decrease in the moderately dense forest category (canopy cover 40-70 per cent). 3. forest cover outside recorded forest area 1. first recorded as part of ISFR 2015 2. isfr 2021 shows that close to 28 per cent of the forest cover is outside the recorded forest area i.e. **19.72 Mn Ha forest cover outside RFA** 3. About 12 per cent of the very dense category of forests is also outside the recorded areas 4. increase in forest cover between 2019 and 2021 has happened primarily because of the growth outside the recorded area. While the forest cover within recorded forests area has witnessed negligible increase, the growth outside has been 0.76 per cent 5. This shows that forests are growing because people are planting trees on their individual lands, and are planting non-forest species, since there are huge restrictions on planting and felling trees listed in the Indian Forest Act, 1927 6. Roughly 40 per cent of the open forests are in the outside recorded areas and in all probability, this is where the tea, coffee or other private plantations would be counted as part of forest cover. 4. Thus India's total forest and tree cover is 71.38 (51.66 inside RFA + 19.72 outside RFA) Mn Ha + 9.6 Mn Ha tree cover (all outside RFA)= 80.98 Mn Ha. 5. Forest and tree cover outside RFA= (9.6 + 19.72)/ 80.98 = 36% i.e. 36% of INdia's totalgreen cover is outside RFA. 6. This land outside recorded forests also contributes to 38 per cent of the forest sinks in the country, acc to FSI

Answer 380

1. Since isfr 2003, the biennial surveys also include Trees Outside Forests (tof) as a category. In this category, tree cover includes patches of trees and isolated trees on areas less than one hectare 2. These scattered trees altogether make up close to 10 million ha of land area which is 2.89% of the geographical area. 3. Maharashtra has had the highest increase in tree cover and a large part of that is due to horticulture.

Answer 381

* **The top five states in terms of increase in forest cover** are Andhra Pradesh (647 sq km), Telangana (632 sq km), Odisha (537 sq km), Karnataka (155 sq km) and Jharkhand (110 sq km). * **Among the mega cities in the country,** Ahmedabad has been the biggest loser when it comes to forest cover. * **Area-wise,** Madhya Pradesh has the largest forest cover in the country followed by Arunachal Pradesh, Chhattisgarh, Odisha and Maharashtra. * 17 states/UTs have above 33 per cent of the geographical area under forest cover. * Out of these states and UTs, Lakshadweep, Mizoram, Andaman & Nicobar Islands, Arunachal Pradesh and Meghalaya have more than 75 per cent forest cover.

Answer 382

Total forest cover in the North Eastern region is 1,70,541 sq km, which is 65.05% of its geographical area. There has been a decrease of forest cover to the extent of 765 sq km (0.45%) in the NE. Except Assam and Tripura, all the States in the region show decrease in forest cover. **_2021 report:_** **The north-east did not show positive results as the current assessment** showed a decrease of forest cover to the extent of 1,020 sq km in the region. **Arunachal Pradesh lost the maximum forest cover of 257 sq km,** followed by Manipur which lost 249 sq km, Nagaland 235 sq km, Mizoram 186 sq km and Meghalaya 73 sq km. **In total 140 hill districts of the country, the** forest cover reduced by 902 sq km in the last two years. In the 2019 report, the forest cover in the hill regions had increased by 544 sq km.

Answer 383

1. ISFR 2021—about 60 per cent of total forest cover i.e. ~42 Mn Ha and 73 per cent of the very dense forests—is concentrated in districts classified as “tribal” by isfr 2021. These districts are listed under Schedule V of the Constitution as habitats of Scheduled Tribes. These 218 districts, covering states of the Northeast and located in parts of central India, highlight the resource curse of the richest lands being the habitat of the poorest. 2. The total forest cover in the tribal districts is 4,22,351 sq km, which is **37.54% of the geographical area of these districts.** 3. There has been a decrease of 741 sq km of forest cover within the Recorded Forest Area/ Green Wash (RFA/GW) in the tribal districts and an increase of 1,922 sq km outside. Recorded Forest Area: The area recorded as forest in the Government records. Green Wash: The extent of wooded areas generally shown in light green colour on the Survey of India toposheets. 1. There has been a decline in tree cover inside forests due to tribal populations getting “land titles” (patta) and there has been a rise in trees outside the forest area due to an increase in tree plantation and afforestation activities.

Answer 384

Mangrove cover in the country has increased by 54 sq km (1.10%) as compared to the previous assessment. 2021 report: * an increase of 17 sq km in mangrove cover in the country as compared to the previous assessment of 2019. * Total mangrove cover in the country is 4,992 sq km. * **Top three states showing mangrove cover increase** are Odisha (8 sq km) followed by Maharashtra (4 sq km) and Karnataka (3 sq km).

Answer 385

* It estimates that there are 53,336 million bamboo clumps in the country, up from 13,882 million in 2019. * The bamboo bearing area is estimated to be 15 million ha—roughly 20 per cent of the forest cover in 2021. * But the potential of this resource remains unutilised because of all the restrictions that come with cutting and transporting trees. * After much discussions, the India Forest Act, 1927, was amended in 2017 to remove bamboo from the definition of tree to remove restrictions on its felling and transit in non-forest lands, but the progress is slow.

Answer 386

The estimation of forest stock is the volume of all living trees in a forested area. It is a critical indicator to measure sustainability—productivity of forests—and also the basis of calculating biomass and carbon stock 2021 report: * The total carbon stock in the country’s forest is estimated to be 7,204 million tonnes and there is an increase of 79.4 million tonnes in the carbon stock of the country as compared to the last assessment of 2019. * The annual increase in the carbon stock is 39.7 million tonnes. * a 4 per cent increase in the growing stock in the country as compared to 2019, of which the bulk is from forests outside the recorded area * when compared in terms of growing stock, the land with trees outside forest is more productive (61.35 cubic metres per ha) than that in the recorded forest (56.60 cubic metres per ha)

Answer 387

The total number of wetlands located within the RFA/GW is 8.13%. Amongst the States, Gujarat has the largest area of wetlands within RFA in the country followed by West Bengal.

Answer 388

A total of 25.87 million ha of recorded forest area—forest land under the control of state government’s forest department—is not accounted for in the “India State of Forest Report 2021” This is India’s forest area—land classified as forests; land which is out of bounds for all other purposes than to grow trees on. According to the isfr 2021, the recorded forest area in the country is 77.53 million ha, which is some 23 per cent of the country’s geographic area. Over the past three decades, this recorded forest area has remained more or less the same. But the total forest cover inside RFA is only 51.66 mn Ha. This means that 25.87 Mn Ha of area is under RFA but does not have forests on it. This land is not even classified as “scrub”. Forested Madhya Pradesh is missing 3 million ha—the difference between recorded forest area and forest cover is close to 32 per cent; in Jharkhand the difference is over 50 per cent It is not possible to brush aside almost 26 million ha. This is land, which if available, should be used for growing trees. If the remote sensing technology, used by fsi can count individual standing trees on land, it certainly can assess the state of this land— recorded as forest on paper. Otherwise, we have paper forests, not real ones.

Answer 389

The biggest takeaway from ISFR 2021 is, therefore, that forests with forest departments are not growing; and one-third of their land is not even fit for assessment. Forest cover is growing in spite of the government, not because of it.

Answer 390

1. 1st gen forest mgmt: Forest management started in India with the colonial British government, which took away community lands and nationalised them. The forests were meant for extraction to aid the colonial government’s economic exploitation of the country’s resources. first phase of post-Independent India continued this extractive system.

Answer 391

1. 2nd gen: second phase started in the 1980s, when the Forest Conservation Act and its subsequent amendments were passed, centralising the “diversion” of forest land. The push for this was the growing awareness of the rate of deforestation in mid 1980s

Answer 392

1. The third phase came with the mission for afforestation— 1. first it was about growing trees outside forests, in the wastelands. 2. Soon it became clear that the real wasteland was in the lands controlled by the forest department. It also became clear that survival of the trees required people cooperation. —it required villages to protect the land and to be partners in afforestation. 3. Thus started the Joint Forest Management (jfm), under which local communities would get usufruct rights to forest produce like grass and would guard the land in return so that forests grow 4. jfm did not succeed because it was a scheme in which state forest departments remained unwilling participants. The forest department showed up only when the trees, protected over the years, were ready for harvest 5. As part of the agreement, money was to be transferred to the village community. But as has been documented in cases from across the country, the final cheque paid for the forest produce was for such small amounts that it was a joke on the community. It broke trust of people

Answer 393

1. The fourth phase continues till today where forests are a permanent battle ground 1. The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act (fra), 2006, has corrected a historical injustice, giving communities rights over land they have been living on 2. till February 2022, some 1.71 million ha of forest land was “settled” as individual rights to people. 3. But there is little attention to the need to afforest these lands and more

Answer 394

1. on the one hand, there is a need for enhanced protection of the remaining forests for ecological security, and on the other, there is a crucial need to build resilience of communities who live in these habitats—all in the times of increased risk because of climate change. 2. —we must shed reticence to plant what will be cut. The fact is that while the first phase of forest management in the country was extractive and exploitative, this 4th phase continues to be based on conservation to the extent that felling trees planted on one’s own land has become a crime. Today, India has to import much of its wood products, and according to a recent report by the International Tropical Timber Organization, this is often sourced from illegally cut forests in Africa and other nations.

Answer 395

1. PROTECTION OF THE REMAINING VERY DENSE AND ECOLOGICALLY SIGNIFICANT FORESTS IS CRITICAL 1. forests for highest level of protection should be identified and this data be made available so that clearance is not granted for projects in such areas 2. e bulk of these very rich forests are found in the habitats of the poorest people in the country. This means doing much more to build strategies for ecological payments to the communities that co-exist on these lands 3. The grant by FC based on forest cover of state has been made unconditional by 14th FC. which means the states are free to use it as they want, but nobody really knows where it comes or goes. It seems the idea of ecosystem payment for conservation, has been lost. This payment needs to be given to communities that live near the protected, high-value forests. This payment is for ecological services rendered because conservation is happening in their backyard and at their cost. 2. PLAN TO CUT AND PLANT AGAIN ON FOREST LAND WITH COMMUNITIES 1. for community forest management to work, trees will need to be cut and then planted again, and this means making a business of the minor and major forest produce. Felling of trees is not the problem; the problem is our inability to replant and to regrow them. This is what needs to be fixed. It is time we brought back the saw-mills so that wood can be used to replace cement or aluminium or steel in housing and in furniture. We need a woodbased future 3. END THE LICENSE-RAJ ON TREES OUTSIDE FORESTS 1. isfr 2021 shows that people are planting trees on their land against all odds. 2. In India today, it is literally a crime to fell a tree even if you have planted it on your own land 3. Under the Indian Forest Act 1927, timber or other produce derived from trees outside forests are treated as forest produce. This is not all. State governments have added to this through their own Acts that govern felling and transit of different tree species. Today, it is a task riddled with high transaction costs and harassment

Answer 396

work the law to make this happen at scale. India’s tryst with forests started with the Chipko movement, when women living in the high Himalayas “hugged” trees to stop the felling by woodcutters. But we misinterpreted the movement. The women stopped the felling, not because they did not want the tree cut, but they wanted the right to decide when the tree would be felled. They knew their survival was intrinsically linked to forests—they needed these lands for fodder and for water conservation. We heard that trees had to protected at all costs; not that we needed to build a sustainable future that would be based on the utilisation of wood for local economies

Answer 399

The original law provided for the conservation of subsoil water and/or prevention of erosion in areas found to be subject to erosion or likely to become liable to erosion. ● As per Section 3 of the original act, the government has powers to bring any area ‘subject to erosion or likely to become liable to erosion’ under the ambit of the PLPA through a notification. ● But, a new section- Section 3A, has been inserted into the Bill to exclude certain areas from the ambit of the Act. What are the concerns? ● Under its provisions, the PLPA won’t apply to ‘the lands included in the final development plans, any other town improvement plans or schemes’ published under the provisions of many laws like Haryana Municipal Corporation Act, 1994, the Gurugram Metropolitan Development Authority Act, 2017. ● Environmentalists feel that the latest move by the government has exposed thousands of acres land falling on the hills and foothills of Aravallis, which cover over 26,000 acres in Gurgaon and Faridabad districts, to mining and real estate development.

Answer 420

a slimy layer of grey or green sludge ‘Sea snot’ is marine mucilage that is formed when algae are overloaded with nutrients as a result of water pollution combined with the effects of climate change. The nutrient overload occurs when algae feast on warm weather caused by global warming. Water pollution adds to the problem. Environmental experts have said that overproduction of phytoplankton caused by climate change and the uncontrolled dumping of household and industrial waste into the seas has led to the present crisis. Turkey’s Sea of Marmara, that connects the Black Sea to the Aegean Sea, has witnessed the largest outbreak of ‘sea snot’. The sludge has also been spotted in the adjoining Black and Aegean seas. A ‘sea snot’ outbreak was first recorded in the country in 2007. Back then, it was also spotted in the Aegean Sea near Greece. But the current outbreak in the Sea of Marmara is by far the biggest in the country’s history. Impact: 1. can cause mass deaths among the fish population, and also killed other aquatic organisms such as corals and sponges. 2. If unchecked, this can collapse to the bottom and cover the sea floor, causing major damage to the marine ecosystem. 3. Over a period of time, it could end up poisoning all aquatic life, including fishes, crabs, oysters, mussels and sea stars. 4. affecting the livelihoods of fishermen. They have said that the sludge is getting collected in their nets, making them so heavy that they break or get lost. Moreover, the mucilage coating the strings make the nets visible to fish and keep them away. 5. Some experts have also warned that the ‘sea snot’ can cause an outbreak of water-borne diseases such as cholera in cities like Istanbul.

The Blue Carbon Initiative focuses on mangroves, salt marshes and seagrasses, which are found on every continent except Antarctica.

Answer 423

SCR Selective Catalytic Reduction (SCR) is an advanced active emissions control technology system that reduces tailpipe emissions of nitrogen oxides (NOx) down to near-zero levels in newer generation diesel-powered vehicles and equipment. SCR is an active emissions control system. Hot exhaust gases flow out of the engine and into the SCR system where aqueous urea (known as Diesel Exhaust Fluid, or DEF) is sprayed onto a special catalyst. The DEF sets off a chemical reaction in the exhaust on a special catalyst that converts nitrogen oxides into nitrogen, water, and tiny amounts of carbon dioxide (CO2) The design of SCR technology is such that it permits nitrogen oxide (NOx) reduction reactions to take place in an oxidizing atmosphere. It is called "selective" because it reduces levels of NOx using **ammonia** as a reductant within a catalyst system (Titanium Dioxide, Vanadium Pentoxide and Tungsten Trioxide). The chemical reaction is known as "reduction" where the DEF is the reducing agent that reacts with NOx to convert the pollutants into nitrogen, water, and tiny amounts of CO2. SCR can reduce NOx emissions up to 90% while simultaneously reducing HC and CO emissions by 50-90%, and PM emissions by 30-50%. Process is very expensive SNCR The main difference is just what the names suggest: **SCR is a reaction in the presence of a catalyst and SNCR does not use a catalyst**. SCR is typically much more efficient at reducing NOx emissions but it is also significantly more costly because of the purchase and maintenance of the catalyst.

Answer 424

* Removal of Sulfur Dioxide is called as Flue-gas Desulphurization (FGD). * It seeks to remove gaseous pollutants viz. SO2 from exhaust flue gases generated in furnaces,boilers, and other industrial processes due to thermal processing, treatment, and combustion. **Common methods used:** 1. Dry FGD: In Dry scrubbing injection system, dry hydrated lime is used as a regent. It yields a dry final product 2. Wet FGD: a shower of lime slurry is sprayed into a flue gas scrubber. Product is a wet calcium sulfite and wastewater Cement mfg, construction of structural fills and agricultural applications utilize significant volumes of FGD products * The Centre had initially set **a 2017 deadline for thermal power plants to comply with emissions standards for installing Flue Gas Desulphurization (FGD) units** that cut emissions of toxic sulphur dioxide. * That was later changed to varying deadlines for different regions ending in 2022. Under the latest proposal, no new dates have been set.

Answer 432

* Any hydrocarbon fuel that is produced from an organic matter (living or once living material) in a short period of time (days, weeks, or even months) is considered a biofuel. * Biofuels may be solid, liquid or gaseous in nature. * **Solid:** Wood, dried plant material, and manure * **Liquid:** Bioethanol and Biodiesel * **Gaseous:** Biogas

Answer 433

* **First generation biofuels:** * These are made from food sources such as sugar, starch, vegetable oil, or animal fats using conventional technology. * Common first-generation biofuels include Bioalcohols, Biodiesel, Vegetable oil, Bioethers, Biogas. * Though the process of conversion is easy, but use of food sources in the production of biofuels creates an imbalance in food economy, leading to increased food prices and hunger. * **Second generation biofuels:** * These are produced from non-food crops or portions of food crops that are not edible and considered as wastes, e.g. stems, husks, wood chips, and fruit skins and peeling. * Thermochemical reactions or biochemical conversion process is used for producing such fuels. * Examples include cellulose ethanol, biodiesel. * Though these fuels do not affect food economy, their production is quite complicated. * Also, it is reported that these biofuels emit less greenhouse gases when compared to first generation biofuels. * **Third generation biofuels:** * These are produced from micro-organisms like algae. * Example- Butanol * Micro-organisms like algae can be grown using land and water unsuitable for food production, therefore reducing the strain on already depleted water sources. * One disadvantage is that fertilizers used in the production of such crops lead to environment pollution. * **Fourth Generation Biofuels:** * In the production of these fuels, crops that are genetically engineered to take in high amounts of carbon are grown and harvested as biomass. * The crops are then converted into fuel using second generation techniques. * The fuel is pre-combusted and the carbon is captured. Then the carbon is geo-sequestered, meaning that the carbon is stored in depleted oil or gas fields or in unmineable coal seams. * Some of these fuels are considered as carbon negative as their production pulls out carbon from environment.

Answer 434

1. Bioethanol * It is derived from corn and sugarcane using fermentation process. * A litre of ethanol contains approximately two thirds of the energy provided by a litre of petrol. * When mixed with petrol, it improves the combustion performance and lowers the emissions of carbon monoxide and sulphur oxide. 2. Biodiesel * It is derived from vegetable oils like soybean oil or palm oil, vegetable waste oils, and animal fats by a biochemical process called “Transesterification.” * It produces very less or no amount of harmful gases as compared to diesel. * It can be used as an alternative for the conventional diesel fuel. 3. Biogas * It is produced by anaerobic decomposition of organic matter like sewage from animals and humans. * Major proportion of biogas is methane and carbon dioxide, though it also has small proportions of hydrogen sulfide, hydrogen, carbon monoxide and siloxanes. * It is commonly used for heating, electricity and for automobiles. 4. Biobutanol * It is produced in the same way as bioethanol i.e.through the fermentation of starch. * The energy content in butanol is the highest among the other gasoline alternatives.

Answer 447

A marine heat wave is usually defined as a coherent area of extreme warm sea surface temperature that persists for days to months. Marine heatwaves happen when sea temperatures are warmer than normal for an extended period. MHWs have been observed in all major ocean basins over the recent decade. Causes: ● The most common cause of marine heat waves are ocean currents which can build up areas of warm water and air-sea heat flux, or warming through the ocean surface from the atmosphere. ● Weak winds: Normally, sunlight passes through the atmosphere and heats the surface of the ocean. If there are weak winds this warm water doesn’t mix with the cooler waters below. It sits on top and continues to heat leading to marine heat waves. Impacts of rising marine heatwaves: ● Affect ecosystem structure, by supporting certain species and suppressing others. ● Can change the habitat ranges of certain species, such as the spiny sea urchin off southeastern Australia which has been expanding southward into Tasmania at the expense of kelp forests which it feeds upon. ● Can cause economic losses through impacts on fisheries and aquaculture. ● There is a link between marine heat waves and harmful algal blooms.

Answer 448

Answer 473

The six pillars of the Policy are as follows: • Science and Research • Economic and Human Development Cooperation • Climate and Environmental Protection • Transportation and Connectivity • Governance and International Cooperation • National Capacity Building

Answer 474

(A)Scientific Research, Climate Change and Environment 1. Monsoons: The changes occurring in the Arctic are yet to be understood fully, but it is clear that they have been impacting global weather, climate and ecosystems including the monsoons in India. 2. Rising Sea Level: The ice loss in the Arctic is a major contributor to global sea-level rise6 and it can have a significant impact on India, especially over its 1,300 island territories and maritime features. 3. Himalayas: The Arctic and the Himalayas, though geographically distant, are interconnected and share similar concerns. The Arctic meltdown is helping the scientific community to better understand the glacial melt in the Himalayas, which has often been referred to as the ‘third pole’ and has the largest freshwater reserves after the North and South poles ▪ The study of Arctic is therefore critical to Indian scientists. (B) Economic and Human Resources 1. Mineral Resources and Hydrocarbons 1. Arctic region has rich deposits of coal, gypsum and diamonds and also substantial reserves of zinc, lead, placer gold and quartz. 2. Greenland alone possesses about a quarter of world’s rare earth reserves. 3. India is the third-largest energy-consuming country in the world, the third-largest oil importer (83 per cent) and the fourth-largest importer of gas which caters to almost half of the total gas consumption. 4. Arctic can therefore potentially address India’s energy security needs and deficiency of strategic and rare earth minerals.

Extinction rebellion, aka ‘XR’ ## Footnote ● Initially, launched in the United Kingdom on October 31, 2018, as a response to a report by IPCC ● Now, it is a global movement which seeks to “rebel”, and asks groups to “self-organise”, without the need for anyone’s permission, to come up with collective action plans as long as they adhere to the group’s core principles and values. ● It is a decentralised, international and politically non-partisan movement using non-violent direct action and civil disobedience to persuade governments to act justly on the Climate and Ecological Emergency. The group has “three core demands” of governments around the world. ● It wants governments to “Tell the Truth”, to “Act Now”, and to “Go Beyond Politics” in order to confront the climate and ecological emergency that the world is faced with. ● The group had announced a “Declaration of Rebellion” at launch, involving a public act of civil disobedience in London, demanding that the government reduce carbon emission to zero by 2025. ● The eventual plan was to coordinate actions in other countries and to engage in an “International Rebellion” in March 2019. ● The XR global website, however, states that the movement is “strictly non-violent”, and that they are “reluctant law-breakers”. ● In April 2019, Greta Thunberg, the teenage Swedish climate activist, lent her support to the group by speaking to its members in London. XR and India: ● The movement claims to have been inspired by 15 major civil disobedience movements around the world, including, apart from Women’s Suffrage and the Arab Spring, India’s struggle for Independence. ● It refers to Mahatma Gandhi’s Salt March in 1930. ● XR’s website says there are 19 groups in the country, including in the cities of Mumbai, Pune, Delhi, Hyderabad, Bengaluru, Kolkata, and Chennai.

Answer 479

It refers to the concurrent blending and combustion of biomass materials with other fuels such as natural gas and coal within a boiler, which reduce the use of fossil fuels for energy generation and emissions without significantly increasing costs and infrastructure investments. Benefits of Cofiring: 1. Biomass cofiring is a promising technology to decrease the use of fossil fuels for energy generation and hence mitigate greenhouse gas emissions. 2. Coal and biomass cofiring accounts for the relevant advantages of a relative ease of implementation and an effective reduction of CO2 and other pollutant (SOx, NOx) emissions to the atmosphere. 3. Cofiring biomass with coal may record no loss in total boiler efficiency after adjusting combustion output for the new fuel mixture.

Answer 498

Microplastics are tiny plastic debris that are smaller than 5 mm in length, tinier than even a grain of rice. There are two types of microplastics. Primary microplastics are tiny particles that are purposely designed as such for commercial use, like in cosmetics, nurdles-plastic pellets used in industrial manufacturing and in fibres from synthetic textiles like nylon. Secondary microplastics are formed through the degradation of larger plastic items like bottles, fishing nets and plastic bags. This occurs through exposure to the environment, like radiation from the sun, wind and ocean waves.

Answer 499

For the first time, microplastics have been found in freshly fallen snow in Antarctica. These particles, due to their light weight and low density, might have travelled through air from more than 6,000 km away. However, researchers argued that there is also a possibility that the human presence in Antarctica created a microplastic ‘footprint’. Of the 13 different plastic types found, the most common was polyethylene terephthalate (PET), a type of plastic used in everyday items such as clothes, plastic bottles, packaging etc. The most likely sources of the airborne microplastic are local research stations, due to the clothing worn by staff, broken fragments of plastic equipment and mismanaged waste. There was a much larger concentration of microplastics (nearly 3 times higher) in the samples next to local base camps Threats: 1. shows that the spread of microplastics is so widespread, that even the remotest and least habitable places in the world are now infested by these particles. 2. The presence of microplastics in Antarctica can also worsen the impact of climate change. Ice sheets and glaciers are already rapidly melting, and the report suggests that the microplastics deposited in ice and snow can accelerate the melting of the cryosphere 3. Dark-coloured microplastics, which constituted 55% of the samples collected in Aves’ study, are even more harmful than lighter colours, as they are better at absorbing sunlight and retain more heat. 4. When snow travels in the atmosphere, it binds itself to airborne particles and pollutants, which are then deposited on Earth’s surfaces. This phenomenon is called “scavenging” and according to scientists is a significant way in which microplastics are able to travel and further pollute land and water. When carried by the snow, rain and wind, they can also lead to the risk of possible inhalation of microplastics by humans and wildlife.

Answer 502

Every year between October to November, India’s rice-producing states witness an infestation of Green Leafhopper. the insect is most commonly identified by its name in Bengali — *shyama poka*. Outside the fields of agricultural and biological sciences, especially in West Bengal, the “arrival” of this insect marks the start of the autumnal festivals of Diwali and Kali Puja. cause severe crop damage by direct feeding or indirect transmission of major viral diseases. is a carrier of the tungro disease, which affects cultivated rice, and causes stunted growth, leaf discolouration, reduced tiller numbers and sterile or partly filled grains. The insect feeds on rice by sucking the plant sap and causes damage to the crop by either directly sucking the sap or indirectly, by transmitting viral diseases — in this case, the tungro virus. While the green leafhopper is more distinct and visible because of its green colouring and black markings on its body, there is a similar insect that arrives around the same time. The brown planthopper. Attacks by the brown planthopper result in the drying of the affected plant, which gives it a scorched appearance called “hopper burn”. Recent times have seen a decrease in their numbers. Causes: → increase in use of pesticides → prolonged dry spell, high temperatures, and scattered rainfall → Urban planning and associated factors. If there is no rice cultivation, there is no *shyama poka*.
