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

1. climate disaster As the open-coast, Sundarbans-edge frontline of the district, it is among the most directly exposed to cyclone landfall and storm surge from the Bay of Bengal. So what: Fishing fleets and shoreline settlements bear the brunt of major storms. Source: Department of Disaster Management / Bangladesh Water Development Board
2. environment Its thin Sundarbans-edge mangrove belt, the natural surge buffer for this exposed coast, is vulnerable to further loss. So what: Weakening mangroves leave the shoreline more exposed to surge. Source: Bangladesh Forest Department
3. water Extensive tidal and saline coastal water raises salinity intrusion into farmland and drinking-water sources. So what: Dry-season agriculture and safe water supply are constrained. Source: Department of Public Health Engineering

Probable solutions

• Strengthen coastal polders, multipurpose cyclone shelters, and surge early-warning coverage along the open-coast frontline Responsible: Bangladesh Water Development Board · policy proposal
• Protect and expand Sundarbans-edge mangrove and coastal afforestation belts as a natural surge buffer Responsible: Bangladesh Forest Department · policy proposal
