Smog Stories: Delhi and other nearby regions have witnessed severe air pollution in the winter months for the past few decades. The situation gets worse in November, especially after cases of stubble burning and Diwali celebrations. The air quality turns so poor that Delhiites find it hard to breathe or see through the thick smog. While there are several factors behind the air pollution, one of the key reasons is the burning of crop residue or stubble by farmers in the northern states of India.

This farm practice is responsible for 8.19 per cent of the pollution. While the wind carries the dust particles to Delhi, it stops moving further in the winter months due to the climate change, choking the surface air. Several hazardous greenhouse gases are released due to stubble burning, including carbon dioxide (CO2), methane (CH4), carbon monoxide (CO), and nitrogen dioxide (N2O) at very high levels, reported the Current Agriculture Research Centre (CARC).
