Deformation of the Jambudwip Island of Sundarban Region, Eastern India

Jambudwip Island is well known for its drastic change of shape and the eviction of homelands of the transient folk-fishermen involved in the fishing activities in this island since 1955. Due to various natural causes the shape of this island is deforming and the total land area is reducing at the rate of 1.32% per annum. Spatio-temporal changing pattern of this island since 1973 has been framed on the basis of LANDSAT images and the GIS technology. A comprehensive study has been done on the effective climatic parameter like sea water temperature, frequency of cyclone, rainfall amount, sea level change, etc. as their natural causes. Eviction of fishing community by the government is becoming a major social issue for such excessive land erosion so controversy has arisen on the natural and the social causes of this Island's deformation.
