Watch: Why is stubble burning a problem every year?
Every winter, a thick shroud of smoke spreads across the skies of Punjab and Haryana, eventually engulfing Delhi NCR. This annual phenomenon occurs when the cold, still air traps a toxic mix of pollutants—smoke from stubble burning, post-Deepavali gunpowder residue, and emissions from vehicles and industries.
Despite a reported decline in stubble-burning incidents over recent years, the air quality in Delhi remains alarmingly poor. On one particularly bad day, the city’s Air Quality Index (AQI) peaked at 494, just a few points shy of the maximum observable limit of 500 set by the Central Pollution Control Board (CPCB). For context, AQI levels up to 50 are considered safe, while anything above 300 falls into the ‘inferior’ category.
Why do farmers in the north continue to follow the practice of stubble burning? What are the challenges they face? What are the alternatives?
