Alternative Grains Can Help India Allay Impact of Global Heating on Agriculture -TV Padma

-TheWire.in

Scientists have found that, compared to rice, alternative grains experienced smaller declines in yield under climate extremes. However, there is a catch.

Alternative grains like millets and sorghum could help India cope better with the impact of global heating on agriculture and variations in supply than continuing to rely on rice and wheat alone. This is the heartening conclusion of a new study, but it also cautions that the cultivation area should be selected with care to avoid any production shortfalls.

An international team of scientists modelled crop cultivation and growth and found that, compared to finger millet, pearl millet and sorghum, “rice yields are significantly more sensitive to inter-annual fluctuations in monsoon rainfall on both irrigated and rain-fed croplands.” The team included scientists from universities in the US – University of Delaware, Columbia University, Yale University and Washington State University – and from the International Institute for Applied Systems Analysis, Laxenburg, Austria; and the Indian School of Business, Hyderabad.

Their study shows that allocating more cropland to alternative grains can help stabilise grain production in a variety of climatic conditions. It “adds to the empirical information needed for comprehensively assessing the potential co-benefits and tradeoffs associated with increased alternative grain production,” their paper, published on June 13 this year, says.
