7
Q

What percent of the Odisha coast is accreting (gaining) sediment. Which areas is this happening in

A

45% of the coast.

It is occurring mainly in the major deltas found in the north (such as the Mahanadi Delta)

Q

What are the risks for human occupation and development along the Odisha coast

A

There are risks from storm surges, tropical storms, and tsunamis.
Any hard engineering strategies may shift erosion down drift and threaten sensitive habitats (like salt marshes).
Upstream HEP projects reduce sediment flow from rivers.

Q

What percent of the coast is eroding in Odisha and where is most of this erosion found

A

37% is eroding

The erosion is focused mainly in the south. Much of this area has hard engineering defences in place to protect infrastructure.

Q

How do erosion and accretion rates vary seasonally in Odisha

A

variations in wave energy and river flow cause greater accretion in summer and greater erosion in winter.

16
Q

When did the ICZM begin

A

2010

17
Q

How much of the coast does the ICZM encompass?

A

the ICZM is 196 km long

18
Q

How has the ICZM reduced dependence on the depleting marine resources. How many people has this impacted?

A

Financial aid has been granted to set up alternative practices such as poultry farming

It has impacted 7,500 families

19
Q

How does reducing dependence on depleting marine resources help the population of Odisha?

A

It makes the people more economically secure (since they’re less vulnerable to loss of fish stock) and less vulnerable to climate change impacting their livelihood.

20
Q

How much money was raised to reduce dependence on depleting marine resources (in rupees and GBP)?

A

8 crore, 35 lakh, 39,311 rupees (83.5 million rupees)

£ 797,100 (can round to £800k)

21
Q

Where has the development of ecotourism been centered in Odisha? how many sites?

A

it is centered at 6 different sites around Chilika Lake

22
Q

How has the development of ecotourism in Odisha impacted the local community?

A

There’s been a roughly 55% rise in employment and income for the beneficiaries

23
Q

How has the number of people visiting the ecotourism sites changed due to the ICZM’s developments

A

There’s been an increase of 30%

24
Q

How many cyclone shelters have been built by the ICZM?

A

14

25
Q

Name one city which has had cyclone shelters built by the ICZM. Whereabouts is this city?

A

Puri, near to Chilika Lake

26
Q

How many people can each individual cyclone shelter accommodate

A

1,000 or perhaps 14,000 i will have to check later

27
Q

what else can the cyclone shelters be used for?

A

They can be used as classrooms and for vaccination programs

28
Q

How many hectares of mangroves have been planted by the ICZM?

A

323 Ha

29
Q

What are the two purposes of the planted mangroves in Odisha?

A

To conserve biodiversity

To act as a shelterbelt for the coast

30
Q

Which two species has the ICZM introduced protections for?

A

Olive Ridley Turtles

Estuarine Crocodiles

31
Q

What defences have been installed by the ICZM?

How many people has this benefitted?

A

505 metres of geotextile embankments (soft engineering)

41,222 people benefit from this

32
Q

How has the ICZM’s soft engineering defences against beach erosion benefit farmers?

A

6,900 Ha of productive farmland is now protected from saltwater intrusion

33
Q

How did the mangroves influence the effects of the 1999 Cyclone Kalina?

A

villages behind >= 4km of mangroves saw 0 deaths. Those behind 3km of mangroves saw a sharp rise in death toll

34
Q

How does the ICZM support sustainable development in the area?

A

it provides long term protection against hazard events and erosion through the use of mangroves.

It promotes economic activities that aid growth while moving away from the traditional unsustainable activities like shrimp aquaculture and fishing

35
Q

How effective is the ICZM on a spatial scale?

A

From a spatial perspective, relatively low. It only covers 196 / 480 km (40%). This leaves some areas excluded from the benefits while also meaning that those areas may conduct practices that harm down drift ICZM areas.

36
Q

How do mangroves aid in protecting and preventing floods?

A

the mangroves accrete sediment in their roots as they grow. This accretion hastens during floods as the water rises higher. Eventually a layer of sediment will build up that acts as a natural flood embankment defence.

37
Q

How effective will the ICZM be on a temporal scale

A

The ICZM will likely be quite effective in the long term as it makes use of natural processes (mangroves) to defend against natural hazards (cyclones, floods) as they naturally would.
