Various climate change experts are of the view that the current century would have massive rains due to global warming in wet areas while the dry areas would become drier. We have seen in Pakistan during the year 2010 and 2011 heavy flooding during rains inundating vast areas in Khyber Pakhtunkhwa, Punjab, Sindh and Balochistan with loss of lives and crops. Even in the current year 2013, heavy rains are taking the toll as we experience it during the monsoon season. 

What is not realised is that all rains occur below Tarbela dam and in the absence of any mega dam below Tarbela the flood water generated by heavy rains flows down to sea in the absence of any storage dam. The only site for a feasible dam is at Kalabagh that will have a storage capacity of 6.1 MAF of water which could mitigate to a considerable extent the damage from floods in the three provinces of Punjab, Sindh and Balochistan. But, unfortunately, this was not to be due to disagreement of smaller provinces which are prepared to cut their nose to spite their face by adamantly opposing the vital Kalabagh dam which could give multiple benefits of water, cheap energy and flood control.
