Problems and issues

  1. urbanization Proximity to Chattogram city is driving fast conversion of farmland and low hills to built-up surface, part of the district's expanding settlement footprint. So what: Unplanned growth strains drainage and erodes the upazila's agricultural base. Source: Chittagong Development Authority (CDA)
  2. climate disaster Heavy monsoon rainfall over the district concentrates on the Karnaphuli-linked lowland here, producing waterlogging and seasonal flooding. So what: Low-lying neighbourhoods and cropland face recurrent inundation. Source: Bangladesh Water Development Board
  3. poverty Boalkhali's mean Relative Wealth Index of 0.274 (national rank 422/452) indicates a comparatively high score that still reflects national poverty rather than broad prosperity. So what: Rapid urban edge growth outpaces local services and incomes. Source: Meta Data for Good Relative Wealth Index (HDX)
