The risks are particularly acute in the Himalayan region, where fragile terrains and concentrated infrastructure increase the likelihood of severe economic and environmental damage. Events like the 2026 Nepal floods have also demonstrated the transboundary nature of these risks, affecting downstream regions in India such as Bihar. High exposure to natural hazards in valleys and river corridors can lead to significant economic losses and human displacement. The lack of cumulative project planning and ecological safeguards further intensifies these risks, making disaster-prone areas more vulnerable to extreme weather events.
