“Globally, current withdrawals [of water] of about 4,500 cubic km exceed the availability of about 4,200 cubic km. By 2030, the demand is expected to increase to about 6,900 cubic km, with a slight drop in availability to 4,100 cubic km. Thus, by 2030, a global deficit of 40 per cent is forecast. For India, the annual demand is expected to increase to almost 1,500 cubic km, against a projected availability of 744 cubic km; a deficit of 50 per cent”
