Abstract
Sagar Island, located at the confluence of river Hooghly and the Bay of Bengal, is the largest inhabited island in the Indian Sundarbans. This paper presents the time-series analyses of the land use and land cover (LULC) of the island for the four decades of 1986, 1996, 2006 & 2014 by using multi-temporal Landsat satellite data under ten classes - mangrove, settlement with vegetation, agriculture land, creek, waterbody, other vegetation, mudflat, aquaculture farm, marshy land, and open space. It also studies the tourism growth in the island and uses the Pearson correlation coefficient (CC) method to associate this with the LULC changes. Information on visitation was obtained from the state tourism department. Field visits were undertaken for ground verifications and primary surveys of visitor facilities. Agriculture land and settlement with vegetation emerged as the dominant land uses, with the former shrinking by 25% and the latter growing by 38% at the end of the study period. About 20% growth was also observed in the number of tourist beds during the same period. The results of the Pearson CC favor a strong correlation between the two and indicate that the dynamics may be largely attributed to the increase of new settlements and visitor infrastructures.
