Ecological Footprint MEDC

A

UK

  • Total EF = 321,621,000 global hectares
  • Per capita EF = 5.45 hectares
  • UK residents are within the top 14% of the global population in terms of the size of their impact on the global environment
  • EF = 3x land area of UK
  • EF would need reducing 70% to be ecologically sustainable (reach fair Earthshare = 2hectares each)

Q

Local Scale Success: Footprint Reduction

A

Santa Monica (City near LA, California)

  • elects representatives to local and state Gov that are willing to be leaders on environmental, social and economic issues (3 pillars of sustainability = city a sustainable development leader) - commitment to sustainability and political will/leadership = City of Santa Monica’s Sustainable City Program’s official adoption 1994
  • Since 1990 reduction in energy component to EF (geothermal energy, reduction in natural gas and diesel fuel use) - 1990 EF 2,914sq miles or 9.7 ha per person, 2000 2,747sq miles or 9.3ha
  • Increased recycling 1990s - per ton of glass, paper, plastic and metal recycled energy use reduced 50% - 62% recycling rate
  • Solar powered electric vehicle changing stations, aggressive public transport promotions, city employee trip reduction programme

Q

(neo-)Malthusian View 1

A

Haiti Mud Cakes

  • Rural-Urban Migration: Port-au-Prince slums
  • Food imported (poor agriculture) - bill leap 80% this year
  • 2/3 live on less than 50p a day (rising food prices tough = expensive sellers move)
  • Gov lifting emergency subsidies
  • Mud cakes sell 1.3p each
  • Children not at school and aid agencies strained
  • Localised dairy jobs growing = £20mn milk import bill cut

(neo-)Malthusian View 2

A
Sahel (soil erosion)
- 200-600mm rail annually
- famine, dust storms, resource conflict
Causes:
- Population growth 3% a year
- Deforestation
- Overgrazing (lost land: national parks, tourism and commercial farms)
- Temp. increase (droughts)
- Storms = water erosion

Q

(anti-Malthusian) Boserup View Case Study

A

Green Revolution (solution to food scarcity)

  • High Yield Variety Seeds new strains
  • more plants per area, less wind damage, shorter roots = fast uptake, more rice per plant
  • prone to disease, hybrids, expensive, fertiliser use, increases development gap

Q

(anti-Malthusian) Boserup View Examples

A
  • Price decline of natural resources e.g. petrol price declined long-term e.g. 1980-90 prices fell 18% copper, 40% chrome, 3% nickel, 72% tin, 57% tungsten
  • Discoveries e.g. 1950 iron reserves globally 19bn tonnes, 1980 43bn
  • Humans resourceful e.g. billiard balls made from ivory - demand increase = elephants scarce (breeding slower than demand) = look for substitutes = celluloid (plastic prototype a cheaper alternative)

Q

Oil and International Relations

A

USA and Venezuela

  • Venezuela sells oil to USA but threatened to cut them if Colombia (USA allied neighbour) attacked Venezuela (due to allegations Venezuela gives haven to Colombian rebels
  • Would badly impact Venezuela Gov. as depends on oil sales (USA top buyer)
  • Colombia not threatened military so threat to USA likely to show not stand for aggression
  • Chavez (Venezuela President) cut off diplomatic relations with Colombia after evidence shown for Colombian rebel camps in Venezuela

Q

Oil and geopolitical stance now and future

A

USA

  • oil prices could go up in 2017 (political transitions in USA one factor) - Trump into office amongst instabilities with Russia/Syria (uncertainty about foreign and security policy - North American oil production potential to mitigate this
  • USA shale production buried peak oil, balanced supply with demand, increase 2017
  • Trump clear on oil - not impose new regulations that would curtail how and where companies can drill for oil (although much state level)
  • US producers will add market stability - US shale oil production from $79 to $48 per barrel
  • 2014 - OPEC produced more = plummeting prices curtained N American oil investments
17
Q

Environmental Impacts of Changing Oil

A

Deepwater Horizon Oil Spill, Gulf of Mexico

  • largest offshore spill US impact
  • Deepwater Horizon drilling rig explosion = spill from sea floor oil gusher
  • April 2010
  • fires for 36 hours
  • coral reefs affected - blocked sunlight / chemical pollution
  • spill impossible to contain
  • oil gushed out 3 months, 4.9mn barrels, 30yrs to recover
  • 9 species dolphin at risk
  • Migrating birds (50,000 brown pelicans) use beaches rest stops = contamination risk
  • tourism + fishing damaged
  • anthracene levels x2 accepted (toxic)
  • cancer-forming carcinogens (human health risk)
  • 8 US national parks at risk; 400+ animal species; 1,200 fish species
  • 13 died, 17 injured
  • Nov 2012 11,000km2 Gulf closed
  • 20% bluefin tuna killed
  • Nov 2012 6,800+ animals dead
  • bioaccumulation / magnification e.g. whale sharks feed on plankton
  • Nov 2012 BP plead guilty
  • BP $4.525bn fines (ongoing)
  • BP 4yrs Gov monitoring safety practices + ethics + temp ban from new contracts w/US Gov
  • 675 US clams + oysters + 75% US shrimp normally produced risk contamination
18
Q

Fracking 1

A

UK

  • suggest trillions cubic feet shale gas beneath UK - reserves found esp N England
  • Gov believe could contribute to energy needs/security (electricity at half co2 emissions) + thousands new jobs + reduce bills
  • Downing Street said fast-track Shale gas planning applications - Labour called moratorium until sure safe - Govs. Scotland, Wales, N Ireland oppose fracking until research environmental impact
  • Shale gas test drilling = earthquake 1.5, 2.2 Blackpool
  • Fracking uses huge amounts water + carcinogenic chemicals may contaminate groundwater
19
Q

Fracking 2

A

USA

  • 16% wells spill annually
  • 6,600 releases wells 10yr period in 4 states (67% North Dakota - largest 100,000 litres)
  • contamination, risk water supplies + human health
  • 6,648 spills 2005-2014
  • North Dakota 4,453 incidents (spill over 42 US gallons reported, 210 gallons Colorado + New Mexico)
20
Q

Dam

A

Three Gorges Dam, China

  • Yangtze River
  • Reservoir discharges over 700km3 water annually
  • Dam 26 turbines + generates up to 18,000MW annually
  • Advantages: reduce oil dependency, national pride (produces 50% more next biggest dam), protect 10mn+ residents from flooding, improved navigation (boats now reach upstream Chongqing), created jobs construction, tourist destination + leisure opportunities, reservoir store water
  • Disadvantages: sedimentation, increased river traffic, Yangtze river dolphin extinction, seismically active region, reduced discharge/velocity downstream, 1.3mn+ relocated, fertile land loss, $70bn build, archeological treasures drowned, deforestation, flooding downstream still
21
Q

Conservation Strategies: Plastic Bags

A
  • 800,000 tonnes plastic bags used Eu annually; 4bn+ bags thrown away year
  • Pacific Ocean ‘plastic soup’ over 15,000,000km2

Complete Ban

  • Italy banned non-biodegradable bags
  • Bangladesh banned thin bags (clogging drainage system = flooding Bangladesh)
  • Rwanda banned all bags
  • Tanzania banned ultra-thin bags
  • UAE banned all except oxo-biodegradables
  • UK use rose 5% 2010 after 4yrs decline - Friends of Earth in favour as long as doesn’t increase wealth disparities
  • US local laws - city of LA no ban, LA county does

Bag Tax

  • Republic Ireland charge 12p bag = 95% reduction plastic bag litter + within year 90% shoppers using life-long bags
  • levy changes according to no. bags used
  • by 2007 raised 75m euros from levy = Environment Fund
  • Wales, N Ireland 5p levy
  • Wales threatens shops give free bags w/ £5,000 fine

Paper Bags

  • Many used US due to powerful wood pulp industry
  • biodegradable in landfill but higher carbon footprint

Biodegradable Bags
- European commission considering intro. better labelling

22
Q

Conservation Strategies: Recycling Policies in a named area

A

Tunbridge Wells (Borough Council)

  • Green bins = general household waste + non-recyclable - no space = black sack collection service
  • Brown bins = food waste, green garden waste + paper - no space = Hessian sacks
  • Green recycling boxes = one plastic, cartons, cans, foil; one paper + cardboard
  • Bins collected from properties; extra waste North Farm Waste Recycling Centre; residents take glass recycling sites (glass colour separated)
  • High littering local areas + prevent need process separation = saving energy + money
23
Q

Conservation Strategies: Resource Substitution

A

Biofuels substitute for petroleum-based aviation fuels

  • Biofuels release CO2 but growing plants absorbs comparable amount gas
  • Issues: loss biodiversity, food crops price driven up, not sustainable + distraction according to environmentalists, (Greenpeace argued Virgin airline should focus on halting airport expansion instead using biofuels), more likely freeze high altitudes
24
Q

Conservation Strategies: Efficiency in Housing

A

BedZED UK

  • Social housing development London
  • Built w/ heat efficient, recycled / reclaimed materials
  • own combined heat + power fed by wood waste
  • double glazing = reduced window heat loss 50%
  • loft + wall insulation cuts loss 33%
  • low energy light bulbs, energy efficient appliances
  • 33% less water, emits 40% less carbon
  • CHP failed 2005, Reed beds filtering waste water for use in toilets + gardens out of order 7 months, expensive, carbon neutral hard to achieve (most drive cars - car sharing scheme)
  • Typical UK lifestyle carbon footprint = 6.19, BedZED conventional = 4.35, BedZED ideal = 1.9
25
Q

Conservation Strategies: International 1

A

Kyoto Protocol 1997 (Japan)

  • ways to manage climate change / achieve environmental sustainability
  • reduce fossil fuel consumption
  • by 2012 every country reduce carbon emissions 5% below levels 1990; Eu countries 8% (EU countries hit quota by 2012)
  • China exempt as developing - US not ratify for this reason
  • carbon credits to trade emissions (ensure global reduction doesn’t matter who) - countries producing more quota buy from ones don’t e.g. Iceland sell
26
Q

Conservation Strategies: International 2

A

Paris Agreement

  • Paris Climate Conference Dec 2015 - 195 countries adopted legally binding global climate deal
  • Agreed meet every 5yrs set more ambitious targets - track progress
  • non-party stakeholders invited to support efforts
  • EU taking steps implement targets reduce emissions 40% by 2030 (forefront of efforts)
  • Reduce emissions - keep increase global average temp below 2oc above pre-industrialisation levels; limit increase to 1.5oc
  • strengthen societies ability to deal w/ climate change impacts, international support/ developed help developing
