Switching back to coarse cereals can offer multiple benefits: Study -TV Jayan

India can benefit substantially on multiple fronts such as nutritional security, energy and water utilisation and even cut its greenhouse gas emissions if it promotes the cultivation of coarse cereals, showed a study by researchers from India, Austria and the US.

During the Green Revolution of the 1960s and the 1970s, the focus has mainly been on increasing rice and wheat output. As a result, a large number of farmers shifted away from more nutritious coarse cereals to high-yielding crops such as rice, leading to narrowing in the diversity of cultivated crops.

Rice focus

Between 1966 and 2011, the total cropped area for monsoon cereals remained nearly constant, but harvested areas dedicated to monsoon rice increased from 52 per cent to 67 per cent. Currently, rice accounts for 74 per cent of kharif cereals production, 80 per cent of energy and 81 per cent of water used for cereal production in the season. Besides, nearly 90 per cent of greenhouse gas emissions from kharif cereals production comes from rice alone. In a study published in the prestigious journal, Proceedings of National Academy of Sciences, the scientists, led by Ruth DeFries and Kyle Davis of Columbia University in the US, on Tuesday, showed that there can be multiple benefits if farmers were encouraged to switch back to coarse cereals. They found that increasing combined calories supplied by coarse cereals such as finger millet, pearl millet and sorghum from the present 14 per cent to 21-32 per cent can help improve the nutritive value of food, apart from reducing irrigation demand, energy use and greenhouse gas emissions.
