Odisha coastline Flashcards
1
Q
What are the distinctive aspects of the Odisha coastline?
A
- 480km long
- 6 major deltas (hexadeltic)
- 7 rivers eg. Mahandi river
- 1500km2 mangrove forest
- Chilika lake - brackish and salty lagoon home to a wide range of birdlife
- significant sediment store
2
Q
What are the opportunities for development and human occupation at the Odisha coastline?
A
- tourism - coastal beaches and wildlife sanctuaries
- large stocks of fish, reptiles and marine mammals - locals employed in fishing and aquaculture
- potential for tidal, wind and wave energy sources
- offshore oil, natural gas, seabed mining
- cultural and archeological sites
3
Q
What are the risks for development and human occupation at the Odisha coastline?
A
- rapid rates of erosion - 36% coastline is eroding, only 14% is stable
- most erosion is in the south - sea walls and rock armour in place to protect infrastructure and ports
- dense mangrove vegetation in Bhadrak and Beleshwar - levels of accretion are more than 50% higher than anywhere else
- increased threat from storm surges/tsunamis/sea level rise
4
Q
How are tropical cyclones mitigated against at the Odisha coastline?
A
- frequency and intensity of cyclones will increase due to climate change
eg. October 2013 - cyclone Philian, 1 million evacuated, 44 dead, 500,000 hectares of agricultural crops destroyed, $700,000 economic losses
- mitigation strategies include ICZM, relief supplies, broadcast warnings, conducted stages evacuations
5
Q
What management is being used at the Odisha coastline?
A
- ICZM
- cultivate and plant mangroves along the coastline and banks of tidal rivers - recent decades - considerable loss of mangroves due to development of fisheries and economic demands - decrease from 5.1km to 1.2km
- small-scale community-based tourism being developed - will benefit 400,000 people
6
Q
What objectives does the ICZM at the Odisha coastline have?
A
- management of coastal erosion
- vulnerability to disaster
- biodiversity conservation
- livelihood security
- environmental quality management
- conservation of cultural assets
7
Q
Why is the ICZM needed?
A
- huge increase in demand for infrastructure and overexploitation of natural resources due to tourism, rapid urban industrialisation, mining, and oil and gas production
- such rapid depletion, unless arrested, will impact the livelihood, health and wellbeing of the population
- accelerated coastal erosion due to climate change and rising sea levels, and increasing frequency and intensity of storm surges
8
Q
What is the aim of the ICZM?
A
- involves various stakeholders
- integrated approach - sustainable use of natural resources along the coastline
- maintain natural environment
