Problems and issues

environment Hill-cutting and forest clearing on Lohagara's eastern uplands add to the district's tree-cover loss and slope instability. So what: Degraded slopes increase landslide and erosion risk over valley farms. Source: Department of Environment
climate disaster Heavy monsoon rainfall draining off deforested hills produces flash floods along the valley streams and highway corridor. So what: Sudden inundation damages crops, roads, and homes in the lowland. Source: Bangladesh Water Development Board / Department of Disaster Management
poverty Lohagara's mean Relative Wealth Index of -0.038 (national rank 271/452) places it around the national midpoint, below the district's wealthier upazilas. So what: Limited local wealth weakens resilience to hill-runoff flooding. Source: Meta Data for Good Relative Wealth Index (HDX)

Probable solutions

Hill-cutting moratorium with reforestation of denuded slopes and slope-stability mapping 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
