Currently water guzzling crops like paddy and sugarcane, which use up to 60% of available irrigation water, are cultivated in some of the most water scarce regions in the country, says the study

New Delhi:
India needs to realign regional cropping patterns with available water resources to ensure future sustainability of food production, a study released on Thursday said.

Currently water guzzling crops like paddy and sugarcane, which use up to 60% of available irrigation water, are cultivated in some of the most water scarce regions in the country, said the study titled ‘Water Productivity Mapping of Major Indian Crops’ by the Delhi-based Indian Council for Research on International Economic Relations (ICRIER).

The study, sponsored by the apex rural bank National Bank for Agriculture and Rural Development (NABARD), stressed the need to recalibrate crop choices by taking into account yield per unit of water applied, instead of measuring productivity per unit of land.

Growing paddy in the Punjab-Haryana belt and sugarcane in the subtropical states of Maharashtra, Tamil Nadu and Karnataka are classic examples of inequity in irrigation water use, the study said.

The study added that relatively water abundant states in eastern India, such as eastern Uttar Pradesh, Bihar, West Bengal and Assam, lag behind in production of water intensive crops as they have not been able to create effective procurement mechanisms or attract sugar mills to their states.

“Indian agriculture has not aligned its crop choice with natural endowments... so we have cases like Maharashtra where sugarcane uses 65% of the water available while covering just 4% of crop area,” said Ashok Gulati, co-author of the study and agriculture chair professor at ICRIER.
