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 As Feni's coastal frontage with limited mangrove buffer, Sonagazi is exposed to Bay of Bengal cyclone surge and tidal flooding on the estuary. So what: Surge and tides inundate char settlements and reclaimed farmland. Source: Bangladesh Water Development Board
- water Thin permanent surface water and weak coastal protection leave Sonagazi facing saline intrusion and dry-season water stress between floods. So what: Salinity and water scarcity threaten estuary farming. Source: Bangladesh Water Development Board
- poverty Sonagazi's mean Relative Wealth Index of 0.066 (national rank 337/452) is comparatively high but still reflects standing within a nationally poor distribution. So what: Coastal households have limited buffer against surge and salinity. Source: Meta Data for Good Relative Wealth Index (HDX)
Probable solutions
- Coastal mangrove afforestation, embankment strengthening, and surface-water retention on the Feni estuary to buffer surge and dry-season stress. Responsible: Bangladesh Forest Department / Bangladesh Water Development Board · policy proposal
- Saline-management and agro-processing/SME support to diversify estuary-zone livelihoods. Responsible: Bangladesh Water Development Board / Bangladesh Small and Cottage Industries Corporation · policy proposal
