Problems and issues

  1. air quality Tongi's dense concentration of factories and heavy Dhaka-corridor traffic make it one of the most NO2-exposed parts of the manufacturing belt. So what: A large worker and resident population faces high respiratory-health burden. Source: Department of Environment
  2. water Intense industrial water use draws on groundwater while local surface water on the Turag is heavily polluted by effluent. So what: Aquifer depletion and river pollution threaten safe water supply. Source: Department of Environment
  3. urbanization Extreme built-up density with little planned green or open space compounds industrial heat and congestion. So what: Dense, unplanned settlement worsens heat stress and service strain. Source: Local Government Engineering Department (LGED)
