Reduce water use in agriculture, to prevent crisis: Former ISRO chairman

Warning of a water crisis, eminent scientist K Kasturirangan, has said that agriculture’s share in India’s total water usage needs to be brought down, to below 50 per cent and efforts made to preserve and manage every drop

Eminent scientist and former chairman of the Indian Space Research Organisation (ISRO), K Kasturirangan, has called for an agriculture regime, where water requirement comes down from (the current) 80-85 per cent to something like 50 per cent or less. “We need to make sure water bodies in the country are rejuvenated properly,” Kasturirangan, who had served as a member of the erstwhile Planning Commission said, while calling for much more intensive methods of irrigation.

The NITI Aayog, in a report last week, stated that India is suffering from ‘the worst water crisis’ in its history, with about 60 crore people facing high to extreme water stress and about two lakh people dying every year, due to inadequate access to safe water. “By 2030, the country’s water demand is projected to be twice the available supply, implying severe water scarcity for hundreds of millions of people and an eventual six per cent loss in the country’s GDP,” the report noted. Citing data by independent agencies, the report pointed out that with nearly 70 per cent of water being contaminated, India is placed at 120th amongst 122 countries, in the water quality index.

Kasturirangan said there are countries where agriculture accounts for about 40-50 per cent of the total water usage and called for a halt to the ‘indiscriminate exploitation’ of ground water. There is ‘very, very large’ depletion of ground water in northern parts of India, if American satellites have to be believed, Kasturirangan said.

“You know what has happened to Punjab and many other states in the process. The economy simply collapsed. That portends the shape of things to come, if we are not careful about how we are going to use ground water,” he said.

Asked whether India’s water crisis is a ‘scary situation’, he said, “We have to work with the concept that it is a scary situation. Otherwise, you will never be serious in this country. It is a scary situation created by us, by our actions,” Kasturirangan said. Every drop of water has to be saved, properly preserved and managed, he stressed. “We have to develop that culture in this country. We have been very profligate in the use of water, because the monsoon has been generous. This country has faced good monsoons over years and in some of the drought years, we have been compensated, because of better monsoon in the previous year but we should not assume that this will continue in the years to come. So, we have to prepare for it,” Kasturirangan cautioned. He also said Karnataka was in the process of forming a policy for water management, under a committee headed by Mihir Shah, an expert in the field.
