Temporal Change Detection (2001- 2008): Study of Sundarban

Rate of coastal erosion in the Indian Sundarban have been measured to be about5.50 sq kms / year within the time frame of 2001 - 2009 and eventually it is most dominant in the south western edges of the individual islands. Erosion has affected both sandy beaches and mud flats. Even inlands with dense mangrove on the east (like Bhanga duani/Mayadwip, Dalhousi or Bulcherry) have been substantially eroded. Total land area of 6402.090 sq.kms of Indian Sundarbans in the year 2001 has been found to be reduced to 6358.048 sq.kms. in 2009 registering a land net loss of 44.042 sq.kms. This includes erosion of 64.162 sq.kms and the accretion of 20.120 sq.kms.
