The Himalayan region supports about 20 per cent of the world's population. But the ecologically fragile region, the storehouse of the third-highest amount of frozen water on earth, is highly vulnerable to climate change. Among the 12 states in the Indian Himalayan Region (IHR), Assam is found to be the most vulnerable to the changing climate, according to a Department of Science and Technology (DST) vulnerability assessment. The study, "Climate Vulnerability Assessment for the Indian Himalayan Region Using a Common Framework", was done by the Indian Institute of Technology-Guwahati and the Indian Institute of Technology-Mandi in collaboration with the Indian Institute of Science, Bengaluru, to help understand climate change vulnerabilities which could inform development of adaptation strategies and ecosystem management for the Himalayan region. The study was part of the Swiss-funded Indian Himalayas Climate Adaptation Programme (IHCAP).
