Pakistan's own agency undermines Diwali pollution claims

Pakistan's air quality monitoring authority has contradicted assertions that Diwali celebrations in India are responsible for smog engulfing Lahore, instead pointing to extensive agricultural burning within Pakistani Punjab as the main source of air pollution.

The findings emerged as authorities documented over 16,700 farm fires across Pakistan's Punjab province during the period when air quality deteriorated sharply in the city. The discovery has complicated the narrative frequently advanced by Pakistani officials attributing the region's persistent smog crisis to cross-border emissions from Indian festivals.

The data from Pakistan's own environmental agency suggests that the timing and intensity of local crop-residue burning—a common agricultural practice during harvest season—correlates more closely with pollution spikes than activities across the border. Farmers in the region typically burn stubble to clear fields for the next planting cycle, a practice that significantly degrades air quality in surrounding areas.

The findings underscore the complexity of managing air pollution in South Asia, where meteorological patterns, agricultural practices, and seasonal factors create transnational air quality challenges. While seasonal winds can carry pollutants across borders, the evidence indicates that domestic sources remain substantial contributors to the smog affecting major Pakistani cities.

The revelations place pressure on Pakistan to focus enforcement efforts on curbing agricultural burning within its own territory as a immediate measure to improve air quality in urban centers like Lahore, one of the world's most polluted cities during winter months.
