The research paper 'Recent Climate and Air Pollution Impacts on Indian Agriculture' that analyzed yields of wheat and rice crops for 30 years, found that air pollution caused wheat yields in densely populated states to be 50 percent lower than 2010.
Up to 90 percent losses were due to the direct effects of short-lived climate pollutants (SLCPs) like smog, the paper authored by Jennifer Burney, an environmental scientist at University of California.
The findings have implications for global food security as India is a major rice exporter.
The paper further said tropospheric ozone and black carbon have direct effects on crop yields beyond their indirect effects through climate.

"Emissions of black carbon and ozone precursors have risen dramatically in India over the past three decades," it added.

Scientists examined historical data on crop yields, emissions, and precipitation to draw their conclusions.
