Delhi’s Smog Crisis: Unveiling the True Culprits Behind the Hazy Skies

Introduction:
As Diwali approaches, Delhi finds itself engulfed in a thick blanket of smog, even before the festival begins. While it’s no secret that industrial and vehicle pollution have long been contributors to the city’s deteriorating air quality, a recent revelation has shifted the focus to a lesser-known factor: crop burning. In this article, we will explore the root causes of Delhi’s air pollution crisis.
Crop Burning in Punjab:
Traditionally, the states of Punjab and Haryana used to harvest paddy crops and burn the leftover stubble in their fields. This practice has been a longstanding source of air pollution in the region. However, a significant change in weather patterns, with winds now blowing from north to south, has exacerbated the problem.
US Involvement and Punjab’s Response:
The U.S. Agency for International Development (USAID), along with American multinational corporations, advised the Punjab government to address this issue. In response, Punjab implemented a ban on planting rice in June, which shifted the harvest season to October. This move was aimed at conserving subsoil water, as the overuse of irrigation and fertilizers was depleting water resources and reducing soil moisture.
The Rice Paradox:
One might wonder why rice cultivation, a staple crop, would be affected by these measures. It turns out that the rice grown in Punjab is unfit for human consumption due to high levels of fertilizers and reduced soil moisture. Instead, it is primarily used as cattle feed at a lower price. Farmers, who were initially critical of these changes, have had to adapt to this shift.
Underlying Water Crisis:
Ironically, despite these efforts to save water, the rice crop’s unconventional use in cattle feed requires more underground water. This situation creates a unique conundrum, as the maze of crop management, fertilizer use, and water conservation efforts ultimately impacts both farmers and the environment.
The Impact on Delhi:
The ripple effect of these changes is felt in Delhi, where air pollution worsens as a result of crop burning. As Diwali approaches, the city faces not only the traditional culprits of industrial and vehicle pollution but also this lesser-known agricultural issue.
Conclusion:
Delhi’s smog crisis is multi-faceted, and while crop burning in Punjab is not the sole cause, it has become an increasingly significant factor in the city’s deteriorating air quality. As the situation evolves, it is essential for stakeholders to work together to find sustainable solutions that balance the needs of agriculture, environment, and public health. Delhi’s quest for clean air continues, with the hope that future Diwalis will bring clearer skies.
