Changing Environmental Scenario

Various morphodynamics factors together with anthropogenic interferences are bringing in substantial changes in the unique ecosystem of Sunderbans Biosphere Reserve. Significant rise in sea level, high rate of erosion and accretion in the deltaic system, change of salinity and temperature of river water, change of river course causing impeded fresh water flow in the estuarine domain, over exploitation of mangrove vegetation which acts as a buffer to cyclonic storms and construction of embankments along the islands are some of the natural and human factors responsible for causing ecological imbalance and depletion of mangrove vegetation with its diverse floral and faunal habitats. A comprehensive multidisciplinary approach for management of Sunderbans as well as awareness among the Sunderbans dwellers about importance of mangrove and its conservation is the need of the hour.
