My dear friend are you ready to give up some part of your land, your home, for these tribal people? who are going to lose all their daily livelyhood. This is like to give water to a thirsty by making other people thirsty. You just cant think to leave your home or city for other people temporarily, then how you can expect that for Kucch Bhuj people (these peoples are also my brothers and sister like narmada valley people)narmad vally people will give their home and land without proper compensation. First make rehabilitation of these people and think about dam.
