Problems and issues

air quality Spreading knit-dyeing factories, brick kilns and traffic add to a district that carries the highest NO2 burden in the country. So what: Industrial emissions degrade local air as factories proliferate. Source: Department of Environment (DoE)
environment Industrial dyeing effluent discharged into local rivers and canals degrades surface water used for irrigation and fisheries. So what: Contaminated water undermines farming and aquatic livelihoods. Source: Department of Environment (DoE)
urbanization Built-up surface is expanding as the upazila fuses into the greater Dhaka-Narayanganj conurbation, often outpacing drainage and zoning. So what: Unplanned growth strains drainage and consumes farmland. Source: Rajdhani Unnayan Kartripakkha (RAJUK) / LGED

Probable solutions

Mandate and monitor functioning Effluent Treatment Plants at dyeing and washing units, with stack-emission and kiln-conversion standards Responsible: Department of Environment (DoE) · policy proposal
Integrate the upazila into a coordinated greater-Dhaka land-use and drainage plan with enforced zoning Responsible: Rajdhani Unnayan Kartripakkha (RAJUK) / LGED · policy proposal
