Why does South Asia have the world’s worst air pollution?
Al JazeeraSmog-ridden cities in Bangladesh, Pakistan and India had the poorest air quality last year, says report. Pakistan scored 73.7 while India’s air had 54.4 micrograms of PM2.5 particles per cubic metre on average over the last year. The report found that poor air quality in South Asia is often down to “brick kiln and other industrial emissions, agricultural waste burning, and cremation practices”. Annual crop burning – whereby farmers in India and Pakistan burn plant residue after harvesting rice to prepare the fields for wheat plantation – is also a contributor to air pollution. According to the Air Quality Life Index published by the Energy Policy Institute at the University of Chicago in August 2023, the average Indian’s life expectancy is reduced by 5.3 years due to PM2.5 pollution.
