Suborno Char (Noakhali)

Local Gov

A newly accreted char upazila on Noakhali's Meghna-estuary coast, formed largely on recently emerged sediment land.

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 Built largely on low-lying accreted char land with little natural buffer, the upazila is acutely exposed to cyclone storm surge and tidal flooding. So what: Settlement on fresh char ground concentrates people where surge risk is highest. Source: Department of Disaster Management
  2. infrastructure Rapid settlement on newly accreted, low-lying char land outpaces surge-resilient siting and basic service provision. So what: New char communities lack safe elevations and resilient infrastructure. Source: Local Government Engineering Department (LGED)
  3. water Saline intrusion into surface and shallow groundwater leaves freshwater scarce across the char and estuarine belt. So what: Drinking and irrigation water are persistently difficult to secure. Source: Department of Public Health Engineering (DPHE)
