Moraine dammed lakes may also have weakened during the devastating earthquake that shook Nepal on April 25. The scientists today said that the weakening of lakes could result in floods in future.

“The threat of further landslides and glacier lake outbursts may increase as snow begins to melt and the monsoon kicks in,” Kathmandu-based International Centre for Integrated Mountain Development (ICIMOD) said in a statement.

The institute is monitoring the recent topographical changes by analyzing the latest satellite images and communicating the findings to the Nepalese government and relief agencies. Some slopes may have been washed away by the earthquake, which could lead to other landslides. “There is an urgent need to assess the impact of landslides for immediate rescue efforts and monitor potential hazards in the future,” ICIMOD said.

Immediately after the disaster, ICIMOD formed a team to analyze the updated satellite images that have been provided from space agencies around the globe. They also set up a webpage to provide latest images, data and information about the recent situation in Nepal.

The team also set up an office near the airport to provide live weather forecasts to the passengers and airport authorities. They provide Google Earth 3D images to help pilots to locate unfamiliar terrain and appropriate landing spots.

The Indian Institute of Technology-Guwahati, Indian Institute of Technology-Mandi and Indian Institute of Science Bengaluru have collaborated to develop a climate change vulnerability assessment for the Indian Himalayan region using a common framework, it was announced on Thursday.

The assessment exercise is unique because for the first time all 12 Himalayan states have used a common framework resulting in the production of comparable state-level and within state, district-level vulnerability maps.

Such comparable vulnerability assessments are useful for the governments, implementers, decision makers, funding agencies and development experts to gain a common understanding on vulnerability, enabling them to assess which state is more vulnerable, what has made them vulnerable and how they might address these vulnerabilities.

The framework and the results were presented here at a national workshop on ‘Climate Change Vulnerability Assessment for States and the Union Territories Using a Common Framework’ organised by IIT-Guwahati and IIT-Mandi with support from IISc Bengaluru, the Department of Science and Technology and Swiss Agency for Development and Cooperation.

The 12 states are Assam, Manipur, Meghalaya, Mizoram, Nagaland, Tripura, Arunachal Pradesh, Sikkim, hilly districts of West Bengal, Himachal Pradesh, Uttarakhand and Jammu and Kashmir.

Highlighting impact of the project, Ashutosh Sharma, Secretary, Department of Science and Technology, said: “The adaptation to climate change is a collaborative effort between appropriate use of technology, a vision that produces policies, a change at ground level and engaging the local communities.”

“These vulnerability maps will play a crucial role in this effort.”

Timothy A. Gonsalves, Director IIT-Mandi, said: “Being situated in the Himalayan region, IIT-Mandi is proud to be a part of this vulnerability assessment exercise and a leader in technology in this region.”

Deputy Head of Mission of the Swiss Embassy Tamara Mona said: “Switzerland, like India, has a long experience in facing the potential opportunities and risks. Swiss national policy for climate change adaptation has been complemented by local government strategies, based on detailed and locally anchored risks assessment, maps and preparedness, plans and actions.” (IANS)
