New Delhi: Burning of crop residue, a common practice by Punjab and Haryana growers, leads to an estimated economic loss of over $30 billion annually, besides being a leading risk factor for acute respiratory infection, especially among children, researchers said on Monday.

The study at the International Food Policy Research Institute (IFPRI) and its partner institutes estimated the economic cost of exposure to air pollution from crop residue burning at $30 billion, or nearly Rs 2 lakh crore annually, for the three northern states of Punjab, Haryana and Delhi. In five years, the economic loss due to burning of crop residue and firecrackers is estimated to be $190 billion, or nearly 1.7 per cent of India’s gross domestic product. Smoke from the burning of agricultural crop residue by farmers in Haryana and Punjab contributes to Delhi’s poor air, increasing the risk of acute respiratory infection by three-fold for those living in districts with intense crop burning.

“Poor air quality is a recognized global public health epidemic, with levels of airborne particulate matter in Delhi spiking to 20 times the World Health Organization’s safety threshold during certain days,” IFPRI Research Fellow and the study co-author Samuel Scott said.

The study, “Risk of acute respiratory infection from crop burning in India: Estimating disease burden and economic welfare from satellite and national health survey data for 250,000 persons”, is co-authored by IFPRI’s Avinash Kishore, CGIAR Research Programme on Agriculture for Nutrition and Health’s Devesh Roy; University of Washington’s Suman Chakrabarti, and Oklahoma State University’s Md. Tajuddin Khan.

It will be published in the upcoming edition of the International Journal of Epidemiology. The study used NASA satellite data on fire activity to estimate the health impact of living in areas with intense crop burning by comparing them with areas not affected by crop residue burning. The researchers observed that as crop burning increased in Haryana, respiratory health worsened.

Health was measured by the frequency of reported hospital visits for acute respiratory infection symptoms. They also examined other factors that could contribute to poor respiratory health such as burning firecracker during Diwali (it usually coincides with time of crop residue burning) and motor vehicle density. In fact, economic losses owing to exposure to air pollution from firecracker burning are estimated to be around $7 billion, or nearly Rs 50,000 crore a year. “Severe air pollution during winter months in northern India has led to a public health emergency. Crop burning will add to pollution and increase healthcare costs over time if immediate steps are not taken to reverse the situation. The negative health effects of crop burning will also lower the productivity of residents and may lead to long-term adverse impacts on the economy and health,” said Chakrabarti. (IANS)
