Problems and issues

  1. environment Hill-cutting and clearing on Raozan's foothill margins feed the district's tree-cover loss, while pressure on the Halda corridor threatens its spawning habitat. So what: Degraded hills and riverbanks raise erosion and harm a critical fishery. Source: Department of Environment
  2. climate disaster Heavy district rainfall and foothill runoff produce flash flooding and bank erosion along the Halda floodplain. So what: Floods damage riverside farmland and disrupt the spawning river. Source: Bangladesh Water Development Board / Department of Disaster Management
  3. poverty Raozan's mean Relative Wealth Index of 0.136 (national rank 375/452) is comparatively high but still reflects standing within a nationally poor distribution. So what: Local prosperity does not guarantee resilience to river hazards. Source: Meta Data for Good Relative Wealth Index (HDX)
