Delhi is once again suffering under a thick, toxic haze. Air quality worsened sharply after the Diwali festival. Headlines called it the worst post-Diwali air in four years. This returns the city to its annual, yet avoidable, pollution crisis.
The crisis is caused by several factors working together. These include fireworks, vehicle exhaust, and the burning of crop residue. Colder weather and low winds trap these pollutants close to the ground. The most debated cause is stubble burning in nearby states like Punjab.
Reports conflict on the exact cause this year. One report claimed a 77% decline in stubble burning due to floods. It blamed firecrackers as the main problem. However, official Punjab data reports a three-fold rise in farm fires over 10 days. Farmers continue to burn stubble because it remains the cheapest way to clear fields.
Authorities relaxed a firecracker ban for Diwali, allowing less-polluting “green crackers.” This court order was widely ignored. Citizens openly burst illegal, highly polluting firecrackers.
The human cost is high. Residents complain of coughing, watery eyes, and breathlessness. Doctors warn of long-term health damage. Yet, political parties resort to a familiar cycle of blame. The Delhi and Punjab governments are in a public war of words. Experts argue the only solution is long-term cooperation between state and federal governments. For now, North India continues to choke in this tragic annual routine.
