Problems and issues
- environment Hill-cutting and forest clearing on Rangunia's CHT-bordering uplands add to the district's tree-cover loss and destabilise slopes. So what: Eroding hills increase landslide risk and silt the Karnaphuli system. Source: Department of Environment
- climate disaster Heavy monsoon rainfall and hill runoff drive flash flooding and riverbank erosion along the Karnaphuli floodplain here. So what: Floods and bank erosion threaten riverside farmland and homes. Source: Bangladesh Water Development Board / Department of Disaster Management
- poverty Rangunia's mean Relative Wealth Index of 0.008 (national rank 310/452) sits just above the national midpoint, below the district's wealthier upazilas. So what: Modest local wealth limits adaptation to flood and erosion hazards. Source: Meta Data for Good Relative Wealth Index (HDX)
Probable solutions
- Hill afforestation and slope-stability mapping with a hill-cutting moratorium to protect the Karnaphuli watershed. Responsible: Department of Environment / Bangladesh Forest Department · policy proposal
- Flash-flood early warning and riverbank protection works along the Karnaphuli floodplain. Responsible: Bangladesh Water Development Board / Department of Disaster Management · policy proposal
