Indicators: Meta RWI (HDX); ERA5-Land; MODIS; Sentinel-5P; VIIRS night-lights; GHSL; Hansen v1.11; CHIRPS v2.0. Exposure: GloFAS v2.1, FABDEM, MODIS LST, ACAG PM2.5, WorldPop 2020.

Problems and issues

1. air quality Its position at a major highway junction concentrates road traffic and roadside dust that add to nitrogen-dioxide and particulate pollution. So what: Highway-corridor emissions degrade local air quality. Source: Department of Environment
2. climate disaster Flat, low-lying floodplain land exposes settlements and paddy to seasonal river flooding and waterlogging. So what: Monsoon inundation damages crops and disrupts movement. Source: Bangladesh Water Development Board
3. infrastructure Heavy through-traffic on the highway junction strains local roads, drainage and safety at the settlement core. So what: Congestion and drainage failure compound waterlogging risk. Source: Local Government Engineering Department

Probable solutions

• Tighten vehicle-emission and dust controls along the highway corridor passing through the upazila. Responsible: Department of Environment · policy proposal
• Floodplain drainage rehabilitation and improved roadside stormwater systems to reduce monsoon waterlogging. Responsible: Bangladesh Water Development Board · policy proposal
