Shift of focus to maize, sorghum, millets would help: Research

Hyderabad:
Excessive focus on cereal production and the resulting pressure on groundwater in some States is no news. But this, a UK-based researcher contends, means that some States are actually ‘exporting’ their scarce groundwater when they market the cereals.

A study by a group of researchers from academic and research institutes from the UK, Germany and India has suggested a shift to maize, millet and sorghum will help the country reduce its scarce groundwater consumption.

They gathered data of production and water-use for five cereal crops (rice, wheat, maize, millet and sorghum), from publicly available sources from 2005 to 2014, to understand the phenomenon.

“The States that are producing and exporting (to other parts of the country) dominant cereals such as paddy and wheat are, in fact, technically ‘exporting’ their scarce groundwater to other States,” Francesca Harris, a researcher with Epidemiology and Population Health of London School of Hygiene and Tropical Medicine, told BusinessLine.

She said Punjab and Haryana are among the top States that overexploited groundwater to produce cereals.

Francesca Harris was here to address the Annual Agriculture, Nutrition, and Health (ANH) Academy Week.

The group published a report ‘More crop per drop - Exploring India’s cereal water use since 2005’. India’s cereal production went up by 26.4 per cent to 238 million tonnes from 188 mt during the period without additional water or land use, thanks to higher yields for most crops.
