The retreat of Himalayan glaciers threatens water security, agriculture, and hydropower generation. GLOFs can cause catastrophic damage to infrastructure, as seen in the Teesta valley disaster. Arunachal Pradesh faces heightened risks due to its rapidly changing landscapes and seismic activity. Expanding glacial lakes in the region could lead to sudden floods, endangering communities and infrastructure. The cumulative impact of multiple hydropower projects in the Eastern Himalayas also raises concerns about ecological and disaster resilience.
