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 Though set back from the open sea, the upazila lies within the cyclone-prone coastal district and is reached by storm surge pushing up the Bishkhali river during major Bay of Bengal storms. So what: Riverside settlements and farmland face flooding in surge events. Source: Department of Disaster Management / Bangladesh Water Development Board
water Saline intrusion along the tidal Bishkhali affects farmland and drinking-water sources, as across the coastal district. So what: Dry-season agriculture and safe water supply are constrained. Source: Department of Public Health Engineering

Probable solutions

Strengthen coastal polders, cyclone shelters, and surge early-warning coverage along the tidal-river frontline Responsible: Bangladesh Water Development Board · policy proposal
Deploy saline-tolerant rice varieties and pond-sand-filter and rainwater systems for dry-season agriculture and safe drinking water Responsible: Department of Public Health Engineering · policy proposal
