Air pollution from stubble burning costing India $30 bn annually: Study

Current Affairs

Air pollution due to crop residue burning in northern India is a leading risk factor of acute respiratory infections and causes an estimated economic loss of $30 billion annually, according to a study unveiled Monday.

Researchers from the US-based International Food Policy Research Institute (IFPRI) and partner institutes found that living in districts with air pollution from intense crop residue burning (CRB) is a leading risk factor for acute respiratory infection (ARI), especially among children less than five years.

The study that estimates -- for the first time -- the health and economic costs of CRB in northern India also found that CRB leads to an estimated economic loss of over $30 billion annually.

"Poor air quality is a recognised 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," said Samuel Scott, IFPRI Research Fellow and co-author of the study.

"Among other factors, smoke from the burning of agricultural crop residue by farmers in Haryana and Punjab especially contributes to Delhi's poor air, increasing the risk of ARI three-fold for those living in districts with intense crop burning," Scott said in a statement.

The study also estimated the economic cost of exposure to air pollution from crop residue burning at $30 billion or nearly Rs 2 trillion annually for the three north Indian states of Punjab, Haryana and Delhi, researchers said.


 To be published in the upcoming edition of the International Journal of Epidemiology, the study analysed health data from more than 250,000 individuals of all ages residing in rural and urban areas in India...Read More
