Problems and issues

environment Hill-cutting and forest clearing across Chandanaish's uplands feed the district's large tree-cover loss and destabilise slopes. So what: Eroding hills increase landslide risk and sediment in valley streams. Source: Department of Environment
climate disaster Very high district rainfall falling on the upazila's deforested hill terrain produces flash runoff toward the valley settlements. So what: Sudden monsoon flooding damages cropland and roads. Source: Bangladesh Water Development Board / Department of Disaster Management
poverty Chandanaish's mean Relative Wealth Index of -0.049 (national rank 262/452) sits near the middle of the national distribution, below several of its district neighbours. So what: Modest local wealth limits adaptation to hill-runoff hazards. Source: Meta Data for Good Relative Wealth Index (HDX)

Probable solutions

Hill-cutting moratorium with slope-stability mapping and reforestation of denuded hills before the monsoon. Responsible: Department of Environment · policy proposal
Flash-flood early warning and small-scale drainage works tuned to the upazila's hill-runoff regime. Responsible: Department of Disaster Management · policy proposal
