The stubble burning season has quietly begun across North India, with early farm fires reported in states neighbouring Delhi. Currently, these incidents remain low and have not yet significantly affected the capital’s air quality. However, experts warn against complacency. The true surge in Air Pollution Delhi typically occurs after the monsoon withdraws, usually around late October. Consequently, proactive measures become crucial to mitigate the upcoming challenges.
Early Stubble Burning Trends Unfold
Satellite data compiled by the Indian Agricultural Research Institute (IARI) indicates 64 farm fire incidents between 15 and 22 September. Punjab recorded 56 of these, while Haryana had three, Uttar Pradesh four, and Rajasthan one. Interestingly, Punjab’s farm fire count slightly increased compared to last year’s 52 incidents, despite recent floods. Amritsar leads the tally with 35 cases, followed by Patiala with seven and Tarn Taran with five. Thus, these early numbers suggest a concerning beginning to the season.
Addressing Air Pollution Delhi Proactively
Anumita Roychowdhury, executive director of research and advocacy at the Centre for Science and Environment, stresses the critical need for early interventions. She highlighted the importance of upscaling key strategies to prevent stubble burning. Furthermore, flood-affected areas face special challenges. These include farmers’ timely access to crop residue management machines and efficient waste stubble collection for industrial feedstock. Immediate evaluation and refinement of enabling measures are therefore vital for stronger preparedness. Studies demonstrate that crop residue burning contributes significantly to high particulate matter (PM) concentrations. This contributes to adverse health effects for the public in Delhi and the NCR region.
Monsoon Withdrawal and Atmospheric Factors
Delhi currently remains largely unaffected. This is due to low fire counts combined with favourable winds preventing smoke drift into the capital. Nevertheless, the monsoon’s withdrawal is imminent. Rainfall is expected to retreat from parts of Gujarat, Rajasthan, Haryana, and Punjab over the next 24 hours. This could set the stage for a more active burning season. Gufran Beig, founder of SAFAR, explains that wind speed and wind direction play a crucial role. These factors influence smoke transfer from burning sites to Delhi. Conversely, this winter season might have a slight advantage. The monsoon has started withdrawing on time. Additionally, festivals will be observed early in October, before severe winter conditions set in. Calm winds and low temperatures typically exacerbate pollution accumulation, making the timing of crop fires critical.
Historical Context and Health Risks
Historical data reveals fluctuating farm fire numbers during the stubble burning period (15 September to 30 November). Punjab saw nearly 50,000 fires in 2022, while Haryana had over 3,600. These numbers underscore the region-wide nature of stubble burning. It poses a significant risk to Delhi and other northern cities as the season progresses, intensifying Air Pollution Delhi. Stubble burning releases harmful gases. These include methane, carbon monoxide, nitrogen dioxide, and particulate matter. Such emissions can lead to smog formation. PM2.5, a harmful category of unburnt carbon particles, can increase more than twice. This occurs during the stubble burning period. Exposure causes respiratory problems, reduced lung function, and exacerbates conditions. These include asthma and heart disease. The elderly and young children are particularly vulnerable.
Frequently Asked Questions
Q1: When does the stubble burning season typically surge in North India?
A1: The real surge in stubble burning usually occurs after the monsoon withdraws from the region, typically around late October, and historically peaks from the end of October to mid-November.
Q2: How has Delhi’s air quality been affected by early stubble burning incidents this year?
A2: For now, Delhi remains largely unaffected. This is because low fire counts combined with favourable winds have prevented smoke from drifting into the capital.
Q3: What are some proposed early interventions to manage stubble burning?
A3: Early interventions include providing farmers with timely access to crop residue management machines and ensuring the collection of waste stubble from fields to provide feedstock and raw material to the industry. Additionally, addressing challenges in flood-affected areas is crucial for better preparedness.
