Causes of flooding in sundarbans
Answers
The people of the Ganges-Brahmaputra Delta—including the metropolis of Kolkata (Calcutta), India—depend on the mangroves of the Sundarbans for protection against storms and floods. As climate change destroys mangroves and worsens storms in the region, it puts lives and livelihoods at risk
The Sundarbans is the world's largest mangrove forest. Designated as a United Nations World Heritage site in both India and Bangladesh,2 it covers nearly 4,000 square miles (10,000 square kilometers). The forest provides habitat for the Bengal tiger, as well as numerous other rare and endangered species of birds, reptiles, and aquatic mammals
Mangroves play a vital role in coastal ecosystems and food chains, by supporting communities of fish and shellfish.3,4Mangroves are salt-tolerant trees and shrubs that help protect coastal areas from increasingly intense tropical storms, waves, and erosion.5,6,7,8 By serving as a flood barrier, they can reduce the damage caused by storms such as cyclones.6,7,8 Damage and erosion to Mangroves leave the coast increasingly exposed and therefore more vulnerable to storms.
More than a quarter of a million people—60 percent of them in Bangladesh—died in tropical cyclones in the last two decades of the twentieth century.
Densely populated coastal areas like the Ganges-Brahmaputra Delta are the most vulnerable to deadly storms.3,9 Scientists determined that intact and healthy mangroves in the Indian state of Orissa saved many lives in a 1999 cyclone originating from the Bay of Bengal.10 Another study found that the 2004 Indian Ocean tsunami caused significantly less damage in areas of southeastern India protected by mangroves and other forests .
