Stubborn Stubble: Pollution Woe Rears Ugly Head Again
New Delhi: Farm fires are steadily beginning to show up on satellite data with the total harvest stubble burning count in Punjab and Haryana having surpassed 500 so far. The delayed withdrawal of monsoon this year means the stubble burning count, which is lower compared with earlier years, is only now expected to go up. A total of 528 paddy residue burnings were recorded from Sept 15 to Oct 8, according to satellite data compiled by Indian Agricultural Research Institute (IARI), which follows the standard protocol 2021 notified by the Commission for Air Quality Management. Of the fires, 222 were recorded in Punjab and 171 in Haryana. In Punjab, 99 farm fires have been spotted in Amritsar alone. Similarly, of the total crop residue burning events in Haryana so far, 38 counts have been recorded in Karnal and 36 in Kurukshetra. In the Sept 15-Oct 9 period, the number of farm fires in neighbouring states were 1,337 in 2023 and 734 in 2022. However, the farmers started clearing their fields of rice harvest stubble late this year after the monsoon withdrew from Punjab, Haryana, Chandigarh and Delhi only on Oct 2. Sunil Dahiya, founder and lead analyst, Envirocatalysts, said, "Stubble burning has begun and is expected to peak by late Oct-early Nov, coinciding with the festive firecracker period. This will likely lead to hazardous pollution levels during that period. Though there may be a slight decrease in stubble burning this year, it is still expected to significantly impact air quality." Dahiya noted, "The episodic nature of stubble burning in Haryana and Punjab, combined with the prevailing winds blowing towards Delhi-NCR, will worsen the air quality. This, along with existing emissions from transport, power and industry, and unfavourable weather conditions such as low temperatures and weak winds, is likely to push air quality to hazardous levels again, as it does annually." He added that a long-term, sustainable solution to the air pollution crisis lay in reducing emissions at sources. But, he observed, efforts across sectors remained insufficient or were too slow to address the scale of the problem. Anumita Roychowdhury, executive director, research and advocacy, Centre for Science and Environment, pointed out that Diwali this year would be celebrated early when colder conditions were yet to set in. "It's a wait-and-watch situation. We will need to consider changes in weather patterns and how successful the states prove in controlling stubble burning," she said. Last year, during the stubble burning period from Sept 15 to Nov 30, there were reports of 39,186 farm fires in Punjab, Haryana, Delhi, NCR districts of UP and Rajasthan. In the same period in 2022 and 2021, the cumulative paddy residue burning events were, respectively, 52,992 and 78,550.
