`Retreating Gangotri will not impact the Ganga'
THE GOVERNMENT has said that the Gangotri glacier, which has retreated by 3 km since 1817, would have no effect on the Ganga's flow. In a written reply to the Lok Sabha, Union Minister for Environment, Forest and Climate Change Anil Madhav Dave said, According to the National Institute of Hydrology, the Ganga is not totally dependent on glaciers for its water even in the headwaters region. The percentage of snow and glacier-fed contribution progressively reduces as one moves downstream. Rainwater and subsurface flows contribute more than 70 per cent of the Ganga's flow at Haridwar. Dave also cited a study by the Union environment ministry and the Indian Space Research Organisation which shows that between 2004 and 2007 most Himalayan glaciers had neither retreated nor advanced.
