Its clearly a case of fallen idols. Pandit Jawaharlal Nehrus "temples of modern India" have failed to deliver and the old faithfuls now have to contend with a new, young band of sceptics. As the debate over large dams versus traditional methods of water harvesting continues, the rosy picture painted by the architects of these temples is gradually losing its colour. A cursory look at the report card of some of Indias major and medium irrigation projects reveals that despite their ever-burgeoning project cost, they have miserably failed to achieve their projected potential. Data obtained by Outlook from the ministry of water resources show that in certain cases, some of these dams and canals dont irrigate even an inch of land.
