- Increasing risk of decreasing mangroves and coastal flooding
- Mangroves
- trees and shrubs that are vital nurseries for fish and other creatures, rich in wildlife.
- roots, that are exposed at low tide trap silt and help create new land
- provide fuel and building materials
- protection from storm surges in low lying coastal areas
- example: 2 villages, the one with mangroves, two people died, whereas in the village without, 6000 people died due to the tsunamis
- Mumbai
- On India's west coast, 2.8million people are at risk from cyclone and monsoon flooding
- 1 in 100 annual probability of a storm surge flood event
- by 2070, numbers of people at risk will have risen to 11million
- the narrow landmass in surrounded by sea on 3 sides, and the reclamation and development of the area between the islands has encroached onto the wetlands
- problem: loss of wetlands due to reclamation, plus the contamination from dumping waste, like the proliferation of slums and destruction of mangroves
- On India's west coast, 2.8million people are at risk from cyclone and monsoon flooding
- The Sundarbans, India and Bangladesh
- many islands in the Indian section have been lost to the sea
- other islands facing rapid coastal erosion, flooding and salinisation of drinking water
- by 2020 , the rising sea level and soil erosion threaten to displace more than 30,000 people
- The Sundarbans
- network of tidal waterways, mudflats and small islands of salt tolerant mangroves
- valuable for its exceptional biodiversity
- the forest is absorbing carbon dioxide and is helping counter global warming
- many islands in the Indian section have been lost to the sea
- Mangroves
- the narrow landmass in surrounded by sea on 3 sides, and the reclamation and development of the area between the islands has encroached onto the wetlands
