Understanding the long-term impact of climate change on Indian crops
Over the past few decades, it has become obvious that climate change, and consequent extreme weather events, can wreak havoc on crop yields. Concerningly, there is a large disparity in agricultural vulnerability between developed and developing countries. In a new study, researchers have looked at major food grains in India to understand the long- and short-term effects of climate change on crop yields.
“Most studies that measure the effects of climate change are looking at year-to-year changes, which are representative of variations in weather and not climate,” said Madhu Khanna (CABBI), a professor of agriculture and consumer economics. “We used data across 60 years to examine how deviations in weather from long-term averages affect the yields of three major cereal crops: rice, maize, and wheat.”
