Air pollution hits wheat
A RESEARCH paper, titled "Recent climate and air pollution impacts on Indian agriculture", featured in the Proceedings of the National Academy of Sciences, says wheat yield in densely populated states reduced by half compared to the figure of 2010. Scientists analysed 30 years of data to bring out the impact of air pollution on agriculture. According to this paper, close to 90 per cent of the loss in production is linked to smog and other pollutants. "We hope our study puts the potential benefits on cleaning up the air on the table," says Jennifer Burney, an author of the study and scientist at the University of California. She adds that agriculture is often not considered when governments debate the economic costs of air pollution and new legislation aimed at combating it.
