Answers

Answered by rajesh6073

"By absorbing some of the force of wind and waves and serving as a flood barrier, mangroves can lessen the damage caused by cyclones and other storms. In early 2010, a disputed Sundarbans island disappeared under the rising waters of the Bay of Bengal.....

here it is

qOooooooooOq: but the question is asking for the reasons of flood but you have given the impacts by flood

rajesh6073: 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

rajesh6073: 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

rajesh6073: 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.

rajesh6073: 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.

rajesh6073: 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

rajesh6073: now

qOooooooooOq: so according to you I mean these answers reason of flood in Sundarbans is only climate change and raised you are speaking about facts on mangroves and impact of flood on humans and Area on mass covered by Sundarban blah blah blah

qOooooooooOq: good now I am totally satisfied

rajesh6073: . thank god
