An airshed is a geographical area where local topography and meteorology limit the dispersion of pollutants away from the area. Research and practice has shown that regulating pollution by taking into account airsheds, rather the arbitrary boundaries of cities and towns, can be a cost-effective way of fighting pollution.
Managing air pollution by taking into account the airsheds has done successfully in Europe and China, whose capital was once as synonymous with smog as New Delhi, India, is today. Beijing’s air is now cleaner chiefly thanks to the creation in 2013 of a powerful airshed-wide authority responsible for the capital, the city of Tianjin and 26 adjacent prefectures. In 2017 pm2.5 levels in Beijing were half those of the previous year.
India is trying to follow this example in and around Delhi. In 2021 it launched a pollution-control agency, called the Commission for Air Quality Management, with responsibility for a 55,000-square-km area, encompassing the capital and parts of Haryana, Rajasthan and Uttar Pradesh… Yet a decisive way to deal with air pollution in India will require a major expansion of this approach, according to the World Bank .
