Abstract

The Indian part of Sundarbans hosts a population of more than 4.4 million people and the land-use-land-cover dynamics of this region has witnessed significant changes in the recent past due to multifarious anthropogenic interventions. Though several pieces of research characterized the land-use-land-cover dynamics of this region, exclusive focus on the ponds of this region is yet to receive any such attention. We selected four administrative blocks of the Sundarban Biosphere Reserve (SBR), namely Sagar, Patharpratima, Gosaba, and Hingalganj, and analyzed the present scenario of the ponds along with their size classes and spatial distribution. The present analysis indicated that Sagar, Patharpratima, Gosaba, and Hingalganj comprise around 9000, 20,500, 11,500, and 7700 ponds. On the whole, the number of ponds varied proportionally with the total area of the blocks; however, the total surface area covered by the ponds did not show any significant relationship with the total number of ponds in each of the blocks. Most of the ponds belonged to the size class having an area between 100 m2 and 200 m2. Spatially, the majority of the ponds were situated within 500 m from the river boundary, plausibly indicating the abundance of aquaculture ponds near the river boundary. Besides, a gross scenario of the spatial distribution of the lentic water bodies and their ratio with the other prominent land-use classes were analyzed in this chapter. However, differentiation in terms of the type of ponds, like the household ponds, community ponds, and aquaculture ponds should be carried out in the future to develop a more comprehensive understanding of both spatial as well temporal dynamics of these crucial lentic ecosystems.
