Summary

This document is GLOF Flyer on Nepal Glacial Lakes by ICIMOD. The Himalayan region in Nepal, often referred to as the third pole due to extensive snow accumulation, is a crucial source of rivers vital for various aspects of life, including drinking water, irrigation, hydropower, and industry. Originating from perpetual snowmelt, rivers like the Upper Bhote Koshi contribute significantly to global river discharge. With the Himalayas containing about 15% of the world's snow and ice-covered area, the region plays a pivotal role in downstream water supply. Climate change-induced alterations in the Himalayan region, including glacial retreat, pose challenges to the livelihoods of the lower Terai region. The dependence on snowmelt during monsoon months and glacial meltwater during the rest of the year underscores the importance of understanding the dynamics of these rivers. Ongoing research is essential to assess potential impacts, such as glacial lake outburst floods, on ecosystems and human settlements. The Himalayan region's changes have far-reaching consequences on water availability and community livelihoods in the Terai region.
