The Sundarbans, the largest mangrove forest in the world, and home to near about 70 lakhs people, animals. The island is one of the victims of drastic climate change. The unforeseen disasters in the area have left people with no hope, People found themselves insecure, continuously struggling for their survival. They are the victim of climate change which is making their survival even worse. They do not want to live their land where they grew up but with less or no basic facilities they were forced to migrate in other areas of the state. Aila in 2009, Bulbul in 2019, super cyclone Amphan in 2020, and recently in 2021 the very severe super cyclone Yaas slammed over Sundarban and flooded the villages, livelihood of people, animal dwellings and the rare Mangroves by breaching the river embankments. The frequent occurrences of the cyclones have imposed difficult situations on the entire ecosystem of Sundarban
In Sundarbans and elsewhere mangrove forests have been destroyed and degraded by unsustainable harvesting as well as by a myriad of coastal development. Considering recent extreme natural events and the risk of rising sea levels due to climate change, there is an increased interest and motivation in strengthening of the river embankments for both livelihoods as well as for the disaster risk reduction benefits, they provide.
Mangroves can reduce the impacts of storms, sea level rise and big waves such as tsunamis. Their roots stabilise the soil, thereby decreasing erosion by wind and waves, and provides a physical barrier that slows down storm surges and tidal waves, thereby reducing their height and destructive power. Whereas Dragon plants and Vetiver grass work as an excellent stabilizing hedge for protecting soil from erosion.
