Pullarao, who was associated with JNU and Chicago University, said at about 5 lakh people are likely to be displaced on account of Polavaram dam being constructed by the Ministry of Water Resources.
"We are sure that the state government will have no objection if central government takes over relief and rehabilitation. It is in public interest," he wrote in his letter to the prime minister.
He further said all central laws should apply for the welfare of lakhs of persons displaced on account of construction of the dam.
