Problems and issues

  1. 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
  2. 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
  3. 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)
