New Delhi: A study by the Geological Survey of India has found that Himalayan glaciers in Gouri Ganga and Alaknanda basin are showing consistent but variable recession, the government told Lok Sabha on Wednesday.

Milam, Poting and Shankalpa glaciers in Gouri Ganga basin and Dunagiri and Bhagirathi Kharak glaciers in Alaknanada basin have been studied by the GSI, Environment Minister Jairam Ramesh said in a written reply to a question in Lok Sabha.

"The rate of recession for Milam glacier glacier is 16.97 meters/year, Poting glacier (05.1 mtrs/year), Shankalpa (06.8 mts/year), Dunagiri (03.0 mtrs/year), Chaurabri (11.0 mts/year) and Bhagirithi Karak glacier (16.7 mtrs/year).

"Further, the study conducted by the Space Application Centre(SAC) revealed that out of 32 glaciers of Gouri Ganga Valley, 20 glaciers have receded between 1990 and 2005 and showing reduction in their area extent by 3.99 per cent," Ramesh said quoting the GSI data.

As per GSI, rescission of glaciers is a natural process and the majority of the Himalayan glaciers are passing through a phase of recession, he said.

The likely impact of the glacier recession includes changes in the river hydrology, increased debris production and siltation of river in downstream regions.

The Union Minister said that to save the glaciers of the Himalayan region, the government has developed guidelines and best practices for sustaining Himalayan Ecosystem.
