Paddy and wheat stubble blazing in Haryana and Punjab states of India: A menace for environmental health

AbstractPaddy and wheat cropping is a widespread farming practice in northwestern parts of India, primarily in the riverine plains of Haryana and Punjab. These fertile lands are well known for extensive agricultural fields; however, they are equally infamous for the burning of paddy and wheat straw and stubble by farmers after the harvesting season. In India, it is reckoned that 22,289 gigagrams (Gg) of paddy stubble biomass is generated annually, and of this 13,915 Gg (62.42%) is set ablaze in the agricultural fields. Haryana and Punjab alone produce 48% of the whole straw production in India, which is openly burned in situ. Burning of farm residue emits various trace gases, such as carbon dioxide (CO2), carbon monoxide (CO), methane (CH4), nitrogen oxides (NOX), and sulfur oxides (SOX), as well as huge quantities of particulate matter (PM), including PM of 10 microns or less (PM10) and 2.5 microns or less (PM2.5), into the atmosphere, causing negative impacts on human health and exacerbating global warming. It is estimated that the burning of one metric tonne (2,204.6 pounds) of straw releases 3 kilograms (kg) of PM, 60  kg of CO, 1,460 kg of CO2, 199  kg of ash, and 2 kg of SO2, causing significant global warming and acid rain. The major problems faced by the local people are eye irritation, dryness of eyes, lung diseases, and chest congestion. The National Capital Region (NCR) of Delhi, Haryana, and Punjab faced a disastrous smog impact during October 2016, and Novemb...
