Here I will just like to quote Tehari dam of India, which has not been properly thought of and planned . After construction of the dam, this mighty river is getting only controlled water to be released at the whims of the project authorities and the politicians. The Ganga , which is holy river of Hindus, does not remain holy now, as the downstream people does not get sufficient water to complete religious activities of Hindus . It has only controlled water like a canal. In December 1965, I went to Calcutta and tried to take bath in Hugli river( tail end of Ganga at Calcutta). I saw human excreta flowing at top layer of water in Ganga. I decided not to take bath in river Hugli ( Ganga). But now with even less flow in ganga, I do not know what has happened to Hugli. Similar case is with river Yamuna, water of which is no potable at Okhala barrage submergence. I do not know how the planners, engineers, politicians, social scientists, health authorities think about Tehari dam. But certainly if I would have been the commander of the project, I would have planned the Tehari dam , so that people on downstream side are not adversely affected. As per the guidelines of the sharing of water of international rivers, the water uses of the downstream nations shall not be adversely affected and should continue to use river water as ae using presently. If Ethiopia wants to be construct a dam, I think there is nothing wrong if the dam is properly planned having no/ little adverse effect on downstream nations and people of Ethiopia living in upstream area and downstream of dam embankment. It will be better if Ethiopia study the effect of three gorge dam of China and try to earn lessons to minimize the adverse effect of proposed Grand Renaissance Dam. It is true that there is adverse effect of construction of dams on environment and ecology of the upstream and downstream areas, which needs to be minimized. The engineers wish to use the maximum percentage of water available at dam site, to increase benefit cost ration even at the cost of disadvantage to upstream and downstream people. This is unfortunate and unacceptable. The world has come closer now. It is high time that the world body "UNITED NATIONS" form a policy regarding construction of dams with the help of people of the world ( both developed and undeveloped nations) from every walk of life political, social, environment, dam engineers, agriculture, ground water, health, education, etc. it should not be like “WORLD COMMISSION ON DAMS”, which was really a tool in the hands of developed nations, who do not wish that the undeveloped nations may harness their water resources and may become economically strong and are able to feed their people without outside support.
