On the authority of former chairman Wapda, Engineer Shamsul Mulk, the number of dams are as follows. US has 9000 medium and large dams and thousands of small dams, China has 6000 medium and large dams and thousands of small dams, India has 4500 medium and large dams and thousands of small dams. Has the world gone mad or have we gone totally bonkers. We have only 2 large dams, about a dozen medium dams and about a hundred small dams. Kalabagh dam with a storage capacity of 6.1 million acre feet is the only large dam that can be built in a reasonable period of time to savePakistanfrom the energy and food crisis. Each additional maf will add 2 billion dollars to the economy ofPakistanevery year. Meantime, Pakistan is losing rupees 300 billion every year. KHURSHID ANWER, Lahore, October 20.
