Swimming upstream on water availability
The prediction of the India Meteorological Department that the South-west monsoon (June-September) accounting for 80% of India’s precipitation would be subpar this year is already putting pressure on prices of fodder, animal feed, onions and potatoes. The agricultural sector depends heavily on the monsoon rains and contributes nearly 14% to GDP and employs nearly half of India’s working population.
Prime Minister Narendra Modi advised that states should set up special courts for speedy trial of hoarders and black-marketers. An advance action plan, with districts, rather than states, at the helm has been put in place. In view of a miserly monsoon, the agriculture ministry has prepared a contingency plan for more than 500 districts. Proposals for offloading food-stocks according to need, permitting imports of essential commodities, setting up a price stabilisation fund aimed at curbing speculation and unbundling Food Corporation of India operations have been mooted. Important as the steps are, they are cosmetic.
Could there be a mechanism that can make agriculture more drought resistant and increase agricultural water use efficiency to produce ‘more crop per drop’?
Excessive use of groundwater and chemical fertilisers in over 50 million hectares of irrigation in India, which is about 20% of the total global irrigated land has caused considerable increase in soil salinity resulting in poor agricultural productivity.
Faced with unclear climate change patterns, it is about time for India to accept that the age of easy water availability is over, and that no food security is viable without water security. With that wired in, India must plunge headlong into scientific agricultural practices like availing of ‘space technology’ that provides an excellent means of logging water inventory by which one can procure reliable information on snow melt run off, groundwater availability, water storage capacity and siltation and sedimentation in reservoirs, tanks, rivers and dams. It is also time to court various low-cost technological innovations to reduce the amount of water used for the production of rice and wheat.
Even though India receives an average of 4,000 bn cubic metres of rainfall every year, only 48% of it ends up in the rivers — of which, due to lack of storage and crumbling infrastructure, only 18% can be utilised.
Mismanagement of water resources, combined with our burgeoning populations, unplanned urban and industrial growth, is so trite a prognostication that nobody seems to pay much attention. A fertiliser-fuelled Green Revolution has run its course and took its toll on soil moisture. We are yet to reach a consensus on major water conservation issues such as river-linking and big dams versus small dams and their social and environmental costs.
