Protesting for land by standing in water

For sixteen days, farmers (whose land was taken away for making Omkareshwar Dam) were standing in neck deep water.Two senior minsters were sent to meet the protesting farmers when Asian division of the Human Rights Commission had called the water protest a "shame"; many protesters had started developing diseases.The dam water was raised to 193 metres without consulting the residents, and the lands of these people submerged. During the "Jal Satyagraha" (water protest) farmers stood in water to claim their right which the Supreme Court had given them(during judgement of May,2011)Compensation was not given even after surrendering their land for making the dam. This had happened in the district of Khandwa in the state of Madhya Pradesh. Government had agreed to give them land as compensation for the land that they had given. The dam was completed in 2006 but the villagers were not given land as compensation as promised.The activists were part of "Narmada Bachao Andolan" who were agitating for rehabilitation for the farmers who had lost their livelihoods. The dam had made a profit of 647 crores in year 2011 to 2012. It would cost only 500 crores to give compensation, but the needs of the farmers were not heard all these years. With this "water protest", they were heard and were compensated. 
The same activists had staged another protest in the district of Harda where 200 protesters were arrested.Why? These farmers had accepted a small package as compensation, and they were not promised new land for their land taken.Harda farmers were given a paltry sum which was highly inadequate;this was forced on them. They do not have a means of livelihood now.They may have to go for Grievance Redressal Authority.The number of people affected are 80000 as the number of villages submerged is 25029. This was done so that the Indira Sagar Project(dam) can produce 1000 MW of power.And the Dam has an irrigation potential of 123000 hectares of land in 574 villages. Maybe a simple canal can be made instead of a dam for irrigation.Solar power and wind power can be used instead of hydroelectric power. Is a dam so important that 80000 farmers are driven out of their homelands and left to fend for themselves?
