Opening · a definition
Mangroves are small trees/shrubs that grow in salt water of tropical regions. eg) Sundarbans Mangroves
Body · points
Geographical factors responsible for mangrove vegetation in India
(1) Tropical warm waters with temperature around 27°C in order to filter salts from saline waters. (2) they prefer saline/brackish waters. (3) Vast continental shelf to promote growth of roots of mangroves. (4) Inter-tidal zones and coastal areas.
Areas of mangroves in India
Climate change posing threats to mangrove vegetation
(1) Rapid change in temperature of coastal waters.
(2) Increase in frequency of cyclones due to rapid global warming. eg) Cyclone Mocha/Tauktae destroyed Sunderbans mangrove.
(3) Changes in salinity of the waters due to mixing of fresh water from glaciers.
(4) A/c to IPCC, 18% of mass would be lost from glaciers by 2050.
Government of India, thus has taken various steps :-
(1) MISHTI programme for promoting convergence of CAMPA and MGNREGA for development of mangroves.
(2) Joining of Mangrove Alliance for Climate change led by UAE and Indonesia in COP27.
(3) Putting mangroves under greatest protection regime - CRZ-I
Close · a way forward
In order to promote development of mangrove and protect it, we need to follow best practise of west bengal where mangroves and shrimp farming are going side by side.
