Water availability for agriculture was estimated to go down by up to 12% from the current level by 2025 if remedial measures were not taken, Indian Council of Agricultural Research director general Mangala Rai warned. "The water availability for agriculture is projected to be 10-12% of what is now available,' he said while inaugurating the Krishi Vigyan Mela here. Mr Rai said farmers would, in fact, require 25% more water in 2025 than what they are consuming currently to produce food grains for feeding the domestic population.
