While India has made substantial improvements over the past decades in the availability and quality of potable water, the fact remains that its is facing a water crisis of gargantuan proportions. This is borne out by evidence and scientific estimates, one of which suggests that by 2030-- that's less than 10 year from now--the country will have only half the water it needs, if the current consumption practices persist. For starters, about four-fifths of the country's freshwater resources are consumed by agriculture, a sector devotes more than half its cultivable land to water-intensive crops such as sugarcane, rice and wheat.
