Over 1400km squared of mangrove forest
Chilaka lake - saltwater lagoon
Olive Ridley turtles
Chilaka lake bird sanctuary- over 150 migratory and resident species of birds
What are the dominant processes in Odisha
1.Extreme tidal variations between monsoon season
2.Frequent cyclones and storm surges
3.Erosion is dominant in south and deposition is dominant in central and north
4.Only 14%of coast is stable ,37%is eroding, 47% is accreting
What are some risks associated with Odisha
1:Vulnerable to storm surges and long-term effects of climate change
2.Industry pollution
3.Only 14% of land is stable
4.Human intervention affects sediment transportation
What are some rewards associated with Odisha
1.Huge potential for offshore wind , tidal and wave power
2.Offshore oil deposits, natural gas,seabed mining
3.Local people employed in fishing
4.Tourism is present - beaches and wildlife sanctuaries
What has the local government done in Odisha to help people move away from marine fishing
Spent money on over 600 projects like fish farms inland, dairy farmers,adding value to fish by salting and drying it

During the day it’s used as schools , vaccination centres, community activities
How much coastline is protected using ICZM management in Odisha
Only 196km out of 480km of coastline
How much homes and land does the 196km of coastline of ICZM protect
146000 homes and 6683 hectares of land
Why was the ICZM strategy chosen for Odisha
For the sustainable use of natural rescources and preserving the natural environment
Why is mangrove planting good as coastline defence and how many have they planted in Odisha
Mangroves break up wave energy and acts as a soft engineering defence
Planted 3 million plants
The roots stabilises the sediment - decreasing erosion- especially good for Odisha as only 14%of there coast is table
What are some disadvantages of mangrove planting
Mangroves are an obstacle to the sea - preventing fishing and trade
They need a lot of space
They are likely to survive so replacing after initial planting is usually expected
