The Water Accord of 1991 allotting 37 percent each to Punjab and Sindh, while giving 14 percent share to Khyber Pakhtunkhwa and 12 percent to Balochistan, is highly unfair to the largest province (Punjab) because it comprises about 73 percent of the total irrigated land of Pakistan. Comparatively, Sindh has only 15 percent of the countrys total irrigated area. The question is: What would Sindh do with a 146.67 percent increase in water allocation over its existing irrigated area? Even granting a 100 percent increase of the 30 percent in its water share would have been more than enough. The Water Accord of 1991, thus, needs to be revised to make it equitable for Punjab. It appears that the 37 percent share of water was dangled before Sindh by Mian Nawaz Sharif, hoping that it would agree to the construction of the Kalabagh Dam. However, unfortunately, it did not happen leaving the entire country high and dry. So would it be wise to pump in 37 percent of water from a future mega dam into Sindh that has only 15 percent of irrigated land? DR MUHAMMAD YAQOOB BHATTI, Lahore, October 1.
