Odisha coastline Flashcards
What are the distinctive aspects of the Odisha coastline?
- 480km long
- 6 major deltas (hexadeltic)
- 7 rivers eg. Mahandi river
- 1435km2 mangrove forest
- Chilika lake - brackish and salty lagoon home to a wide range of birdlife
- significant sediment store
What are the opportunities for development and human occupation at the Odisha coastline?
- 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
What are the risks for development and human occupation at the Odisha coastline?
- 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
How are tropical cyclones mitigated against at the Odisha coastline?
- 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
What management is being used at the Odisha coastline?
- recent decades - considerable loss of mangroves due to development of fisheries and economic demands - decrease from 5.1km to 1.2km
- rising sea levels and increased frequency and intensity of cyclones means integrated management is essential
- ICZM
- cultivate and plant mangroves along the coastline and banks of tidal rivers
What objective does the ICZM at the Odisha coastline have?
- management of coastal erosion
- vulnerability to disaster
- biodiversity conservation
- livelihood security
- environmental quality management
- conservation of cultural assets
Why is the ICZM needed?
- 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
What is the aim of the ICZM?
coordination of activities of various stakeholders in an integrated approach for the sustainable usages of the coastal natural resources maintaining the natural environment
