Satkhira District
Local Gov
The southwesternmost district on the Indian border, Satkhira fronts the western Sundarbans and is dominated by saline shrimp aquaculture and tidal wetlands. It is among the most climate-exposed and poverty-stricken coastal districts, yet shows rapid recent economic and built-up expansion.

Problems and issues
- poverty Satkhira ranks 27th of 64 districts on mean Relative Wealth Index (1=poorest), the poorest in this group, reflecting deep coastal deprivation worsened by salinity and repeated disasters. So what: Entrenched poverty leaves households unable to recover between climate shocks, driving distress migration. Source: Meta Data for Good Relative Wealth Index (HDX), ~2.4 km grid
- water Permanent surface water covers 458.5 sq km of saline tidal rivers and shrimp ghers, a heavily brackish system that limits freshwater for drinking and agriculture. So what: Pervasive salinity makes safe drinking water and crop cultivation a daily struggle for coastal residents. Source: JRC Global Surface Water (permanent water) via Google Earth Engine
- environment Satkhira held about 1,028.4 sq km of mangrove in 2000 along the western Sundarbans and lost 35.3 ha of tree cover over 2001-2023, eroding its protective forest belt. So what: A thinning mangrove buffer leaves communities more exposed to the cyclones that repeatedly strike this coast. Source: Global Mangrove Watch (2000) via Google Earth Engine
- urbanization Built-up surface reached 29.8 sq km recently after about 127% growth since 2000, and nightlights grew 192% (ranking 8th-fastest of 64), with expansion concentrating on low-lying, surge-prone land. So what: Rapid settlement and asset growth in a hazard zone raises the value at risk from each cyclone and surge. Source: GHSL built-up surface (JRC) via Google Earth Engine
- climate disaster With about 1,748 mm of annual rainfall in a low coastal delta and modest warming (air +0.34 C), Satkhira faces recurrent cyclone, storm-surge and waterlogging hazard. So what: Repeated embankment breaches and flooding destroy aquaculture and homesteads across the district. Source: CHIRPS v2.0 precipitation (UCSB Climate Hazards Group) via Google Earth Engine
Probable solutions
- Deploy managed aquifer recharge, rainwater harvesting and pond-sand filters to provide salinity-free drinking water in coastal unions. Responsible: Department of Public Health Engineering (DPHE) · policy proposal
- Rehabilitate coastal polders, raise and maintain embankments, and steer new settlement to the cyclone-shelter network on safer ground. Responsible: Bangladesh Water Development Board · Coastal Embankment Improvement Project
- Restore degraded mangrove fringes and expand community co-management along the western Sundarbans boundary. Responsible: Bangladesh Forest Department · Sundarbans Reserved Forest co-management framework
- Combine salinity-tolerant rice and diversified aquaculture with targeted social protection and disaster cash transfers. Responsible: Department of Disaster Management · policy proposal
