Why India’s smog strategy has failed to solve its out-of-control air pollution
As air pollution soared to unprecedented levels in North India this week, Delhi and neighbouring cities lay shrouded in a dense, smoky haze, bringing with it near-zero visibility. Flights were grounded, and millions sought refuge indoors. With the Air Quality Index touching 500, a level that is considered hazardous even to people without health conditions, Delhi’s local government termed the smog a “national medical emergency.” On Monday, the crisis in the city – which contains India’s capital, New Delhi – drove the country’s Supreme Court to order emergency measures. The court’s decision noted the failure of a central government body, the Commission for Air Quality Management, to prevent deterioration of air quality, despite forecasts of rising pollution levels. The court directed authorities in the region to enforce the highest level of restrictions, including closing schools, halting construction, and limiting heavy vehicle movement and non-essential industrial operations. Doctors reported a sharp rise in hospital visits and admissions for breathing disorders in November. Toxic air also travelled across the border, affecting cities in Pakistan, including Lahore, and sparking calls for “climate diplomacy” and cross-border co-operation. But the air pollution crisis, while especially severe this year, has become an annual occurrence in Delhi, where the cool winter air traps emissions from a variety of sources, including farm fires ignited to clear stubble left over from the rice harvest. Solutions to this perennial onslaught of smog are caught in a political deadlock, with Delhi’s local government and India’s central government, led by opposing parties, the AAP and the BJP, holding each other responsible. Delhi Environment Minister Gopal Rai, for example, called on Prime Minister Narendra Modi this week to approve a proposal to lower the toxicity by seeding clouds, a process that uses dry ice or other materials to encourage rain. Meanwhile, environmental groups, medical professionals, civil organizations and air pollution experts across the country are questioning why, despite repeated promises from various governments and significant investments in anti-pollution measures, authorities have been unable to stem the problem. It wasn’t always this way. Winters in Delhi used to bring a pleasant fog, said Mohan George, a clean air and sustainability expert at the Centre for Science and Environment, a New Delhi-based non-profit. “Things started to change after 2007, when Punjab revised its agricultural policies, delaying the sowing and harvesting of crops,” he said.
