A project led by Nagaland University is conducting a detailed and near-accurate inventory and stability assessment of high-altitude lakes across the Himalayan region, particularly in Sikkim and Arunachal Pradesh. This initiative holds vital significance in light of growing climate vulnerabilities and disaster risks in the ecologically fragile zones of Northeast India.
The study concentrates on assessing Glacial Lake Outburst Flood (GLOF) risks, especially from Tenbawa Lake in Sikkim, while exploring Holocene-era climate linkages to understand long-term environmental changes. Two additional glacial lakes in Arunachal Pradesh are also under close analysis.
Using high-resolution remote sensing data, the researchers aim to identify “potentially dangerous glacial lakes” by evaluating geomorphological factors, slope instability, and permafrost degradation. Separate sub-projects are focused on the Tawang region of Arunachal Pradesh and the Lachung basin in North Sikkim, both known for active geohazards.
This initiative is crucial for building climate-resilient infrastructure and early warning systems in the Himalayan belt, which faces increasing threats from glacial retreat and erratic weather patterns.
