The accelerated glacier loss threatens millions of lives and livelihoods across India and South Asia. Glacial floods, such as those in Sikkim (2023) and Uttarakhand (2021), have already caused significant casualties and infrastructure damage. The retreating glaciers also jeopardise water availability, with most river basins in the Hindu Kush Himalayan region expected to reach 'peak water' by mid-century. This could disrupt agriculture, hydropower, and other economic activities that rely on Himalayan water, which underpins 20% of India's GDP. Additionally, 56 glacial lakes have been classified as 'very high risk,' highlighting the urgent need for monitoring and mitigation.
