The Magsaysay award winner said that, "... Without cultural and social understanding about Ganga, you cannot make it clean Ganga. On the one hand, (you require) science, technology and engineering and on the other hand, you need cultural and social aspects of Ganga. Without an understanding of this it is not possible."
He was speaking on the sidelines of launching the 'World Water Walk for Peace' here.
Queried whether he was of the view that the government is not adopting the right path for rejuvenating river Ganga, he replied "Yeah."
The 'World Water Walk for Peace' launched today in India, as part of an international campaign on conservation of water, would be carried out continuously for the next five years across India and abroad as well.
