Abstract

The Indian Sundarbans Delta is experiencing severe water scarcity that has affected 4.5 million people due to increased salinity levels, restricting access to drinking and irrigation water. Remote sensing data and GIS analyses were used to assess the consumable water availability. The water quality investigation showed variations in pH and salinity levels in surface water post-monsoon season. The central part of the delta had better water quality compared to Sagar Island. Groundwater levels diminished from 3.3 meters BGL in 1996 to 7.67 meters BGL in 2022. Freshwater scarcity and seawater intrusion are affecting agriculture and food security.
