International collaborative research led by Aakash Project* researchers at the Research Institute for Humanity and Nature (RIHN) show an unequivocal contribution of crop residue burning (CRB) to air pollution in the rural/semi-urban regions of Punjab and Haryana, and a relatively lower contribution than previously thought to the Delhi national capital region (NCR). We have installed 30 units of compact and useful PM2.5** in situ instrument with gas sensors (CUPI-Gs) and have continuously recorded air pollutants in 2022 and 2023. New analytical methods have been developed to assess and predict the formation and transport of air pollutants due to emissions from CRB.

A group of international collaborators led by the Research Institute for Humanity and Nature (RIHN) team performed the first quantitative study of air pollution in the north-western India region using 29 low-cost and reliable instruments, demonstrating the advantages of source region observations to link crop residue burning (CRB) and air pollution at local to regional scales.

Study tries to assess brick kilns’ impact on air

Sachicko Hayashida of RIHN from Japan’s Kyoto and at least 20 other scientists from various institutes in Japan and India are now trying to pinpoint their distribution in the national capital region and role in Delhi’s air pollution. Hayashida is the principal investigator of the study.
