What causes air and water pollution problems in Karachi?

Karachi faces significant environmental challenges stemming from rapid urban growth and infrastructure limitations.

Air Pollution

The city's air quality is primarily degraded by fumes emitted from factories and automobiles. Despite the presence of land and sea breezes, these emissions contribute to persistent pollution levels.1

Water Pollution and Sanitation

Water-related environmental issues in Karachi are largely tied to the city's overburdened infrastructure and the rapid expansion of its population. Key factors include:2

• Inadequate Sanitation: A significant portion of the population resides in katchi abadis (urban shantytowns) that often lack basic sanitation services.2
• Infrastructure Deterioration: Confusion regarding the responsibility for financing and providing municipal services has led to the deterioration of sanitation systems.2
• Stagnant Water: High humidity levels in the region hinder the evaporation of stagnant water in various locations, creating persistent environmental hazards.1

While the city utilizes underground drainage systems and sewage treatment plants, the delivery of basic services remains an ongoing challenge for the city's administration.23
