Local Gov

The district seat and commercial-industrial core on the Shitalakshya, the country's textile and knitwear heartland.

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 As the dense factory and traffic core of the district, Sadar concentrates the knit-dyeing, kiln and vehicle emissions behind the nation's highest district NO2 burden. So what: Residents face among the worst urban air pollution in the country. Source: Department of Environment (DoE)
2. environment Industrial dyeing and tannery-adjacent effluent discharged into the Shitalakshya has degraded the river running through the town. So what: Polluted surface water threatens drinking supply, fisheries and public health. Source: Department of Environment (DoE)
3. urbanization Built-up surface is dense and still expanding as Sadar fuses into greater Dhaka, often outpacing drainage, sewerage and zoning. So what: Crowded growth overloads drainage and worsens the urban heat island. Source: Rajdhani Unnayan Kartripakkha (RAJUK) / LGED

Probable solutions

• Enforce stack-emission and brick-kiln conversion standards with tighter vehicle and kiln inspection in the industrial core Responsible: Department of Environment (DoE) · policy proposal
• Mandate and monitor functioning Effluent Treatment Plants discharging into the Shitalakshya with real-time effluent monitoring Responsible: Department of Environment (DoE) · policy proposal
