India’s grain production is vulnerable to climate change, say scientist who have found that the yield of the country’s rice crop can significantly decline during extreme weather conditions. Researchers from Columbia University in the US studied the effects of climate on five major crops in India: finger millet, maize, pearl millet, sorghum and rice.
These crops make up the vast majority of grain production during the June-to-September monsoon season — India’s main grain production period — with rice contributing three-quarters of the supply for the season. Taken together, the five grains are essential for meeting India’s nutritional needs, researchers said.
The study, published in the journal Environmental Research Letters, found that the yields from grains such as millet, sorghum, and maize are more resilient to extreme weather.
Their yields vary significantly less due to year-to-year changes in climate and generally experience smaller declines during droughts. Read More
