"Now, the flow of Ganga has decreased and this has affected its water quality," Joshi said at the inauguration ceremony of Mahamana Malviya Institute of Technology for Ganga Management. "While water conservation is necessary, damming a river should be in keeping with requirements. Instead of copying the west, it is better that development takes place based on our needs," the chairperson of the PAC said.
"The ill-effects of playing with nature are apparent only after a while. This is what has happened with the Ganga," he said.
