Delhi’s Air Quality Crisis

There has been a sharp deterioration in air quality in New Delhi over the past week, with the AQI touching 481 on Monday morning. Several areas recorded an AQI of more than 500. The officials attribute this deterioration to unfavorable weather conditions, which worsened the smog situation.

Contribution of Stubble Burning

The weather forecasting agency of the Ministry of Earth Sciences, SAFAR, reported that stubble burning has accounted for around 38% of New Delhi’s pollution this year, mainly from neighboring states of Punjab and Haryana. Stubble burning refers to the burning of leftover rice straw to clear fields, which worsens the pollution of the region.

Seasonal Smog Issues

Every winter, New Delhi grapples with dense smog: a lethal cocktail of smoke and fog. This is when cold air traps dust, pollutants, and emissions from illegal farm fires. The mix of high pollution, humidity, calm winds, and plummeting temperatures was going to worsen the situation as smoke conditions and low wind speeds were likely to hold until Saturday, officials said.
