The impact of Punjab's farm fires on Delhi's air pollution problem is significant. Here are the key points to consider:
  • Punjab's farm fires, primarily due to the practice of stubble burning after crop harvesting, contribute to air pollution in Delhi.
  • The burning of crop residues releases a huge amount of pollutants, including particulate matter (PM), nitrogen dioxide (NO2), sulfur dioxide (SO2), and carbon monoxide (CO).
  • These pollutants can travel long distances and get trapped in the atmosphere, leading to a deterioration in air quality not only in Punjab but also in neighboring states, including Delhi.
  • During the winter months, when both farm fires and weather patterns are conducive, the problem exacerbates. Calm winds and a temperature inversion trap pollutants in the lower atmosphere, creating a thick layer of smog over Delhi.
  • Studies have indicated that during this period, Punjab's farm fires contribute significantly to Delhi's air pollution, accounting for approximately 25-30% of PM 2.5 concentration.
In conclusion, Punjab's farm fires have a substantial impact on Delhi's air pollution problem, especially during the winter months, contributing to higher particulate matter levels and reduced air quality. Efforts to address stubble burning and improve agricultural practices in Punjab are crucial in mitigating this issue.
