Local Gov

A Meghna-front upazila on the eastern side of Bhola island, long contending with active riverbank erosion of the estuary edge.

Wealth rank 347/452 (1 = poorest upazila)

Indicators: Meta RWI (HDX); ERA5-Land; MODIS; Sentinel-5P; VIIRS night-lights; GHSL; Hansen v1.11; CHIRPS v2.0. Exposure: GloFAS v2.1, FABDEM, MODIS LST, ACAG PM2.5, WorldPop 2020.

Problems and issues

climate disaster On the eastern Meghna front, the upazila faces chronic and severe riverbank erosion alongside cyclone and tidal-surge exposure. So what: Advancing erosion consumes farmland, settlements, and embankment lines. Source: Bangladesh Water Development Board
water Saline and tidal river water surrounds the upazila while safe freshwater for drinking and irrigation is scarce. So what: Salinity intrusion into ponds and aquifers limits safe water supply. Source: Department of Public Health Engineering

Probable solutions

Rehabilitate and raise coastal polders and embankments to current surge standards, with managed retreat zoning for the most erosion-prone reaches. Responsible: Bangladesh Water Development Board · coastal embankment rehabilitation program
Expand managed aquifer recharge, pond-sand filters, and rainwater harvesting for salinity-resilient drinking water. Responsible: Department of Public Health Engineering · salinity-resilient drinking water program
