42 glacial lakes in Koshi Province under severe threat

Khandbari (Sankhuwasabha), Nov 21: Recent data from the International Centre for Integrated Mountain Development (ICIMOD) indicates that 42 glacial lakes in Koshi Province are facing a critical risk. 

During a discussion held today in Khandbari, headquarters of Sankhuwasabha, ICIMOD expert Sharad Prasad Joshi shared insights from the 2020 report on 'Risks arising from rapid changes in Nepal's glaciers and glacial lakes.' Joshi noted that out of a total of 2,069 glacial lakes in Nepal, only 42 located in the Koshi region are classified as highly at risk. 

He warned that a potential burst of a glacial lake could lead to catastrophic loss of life and extensive damage to infrastructure, stressing the importance of heightened vigilance and preparedness. Joshi pointed out that within Sankhuwasabha, four glacial lakes, including those in the Bhotkhola and Makalu areas, are categorized as high-risk. 

Notably, the Talopokhari glacial lake in the Talobarun area is deemed the most vulnerable. He described the lake as approximately three kilometers in length and around 206 meters deep, with surrounding depths ranging from 15 to 25 meters. In partnership with the Department of Hydrology and Meteorology and UNDP Nepal, risk reduction strategies are being developed for these four glacial lakes. 

Additionally, a large pond situated in lower Barun is part of this initiative. Joshi highlighted that if a glacial lake were to burst, numerous settlements and infrastructure in the Arun Valley would be at immediate risk. He also noted that 13 glacial lakes originating from the Tibet region could pose a threat to the northern areas. 

At the event, Neera Shrestha Pradhan from ICIMOD remarked that women, children, and the elderly are often the most affected during disasters, prompting the implementation of programmes aimed at raising awareness and building capacity among these vulnerable groups. Suman Shakya, head of the District Coordination Committee of Sankhuwasabha, underscored the necessity of proactive measures to address the possible risk. (RSS)
