The United Nations Development Programme reports that in severely hazard-prone districts across the delta, up to 87% of households have been displaced at least once due to disasters, with 12% permanently displaced.

Despite living alongside rivers and tidal channels, millions of people in coastal areas struggle to access safe freshwater, especially in districts like Satkhira, where residents may walk miles to collect rainwater during the dry season, a task that falls disproportionately on women and girls.
