The devastating flash floods that swept through the Rasuwa and Nuwakot regions of Nepal have left a trail of destruction and uncertainty, with over 4,700 people still reported missing. The scale of the disaster has been compounded by the formation of a potentially dangerous lake near the Nepal-Tibet border, raising the specter of a second flood. In the aftermath, experts and activists are calling for immediate and sustained investment in early warning systems and climate-resilient infrastructure to mitigate future disasters.
Dikshya Subedi, a climate advocate with over seven years of experience, witnessed firsthand the horror and despair that has gripped affected communities. Despite her background in climate advocacy, she acknowledges the gravity of the situation, emphasizing the need for real, funded investment in early warning systems for glacial and flood hazards in high-risk mountain corridors.
Subedi argues that authorities must urgently map and monitor unstable glaciers, landslide-dammed lakes, and river corridors while restoring damaged sensors and establishing 24/7 real-time communication among mountain monitoring stations and downstream communities. She also advocates for stronger upstream hazard monitoring and river-corridor planning, including transboundary data-sharing with neighboring countries like China.
The formation of a lake near the Nepal-Tibet border is a direct consequence of the massive ice-and-rock collapse in the high Himalayas, which triggered a cascading event in the Lhende Khola, sending a sudden surge of water, rock, and sediment into the Bhote Koshi-Trishuli river system. This event underscores the need for immediate action, as the threat of secondary flooding escalates.
Subedi also stresses the importance of activating clear evacuation triggers, emergency shelters, and multiple warning channels, including SMS alerts, sirens, and local radio, to ensure that people have enough time to move to safety. The warming of the region is destabilizing the cryosphere, including glaciers, glacial lakes, and mountain slopes, which increases the risk of such catastrophic events with each passing year.
Beyond early warning systems, Subedi advocates for climate-resilient infrastructure, locally led adaptation, and disaster preparedness designed with and by the people who live with the risk. This includes meaningful investment in vulnerable communities, especially those downstream, and the construction of bridges, roads, hydropower, and public facilities that can withstand floods, landslides, and other cascading mountain hazards.
Nepal's contribution to global greenhouse gas emissions is less than 0.1 percent, yet the country is among the most climate-vulnerable nations on Earth. Subedi calls for climate justice, demanding compensation for suffering from a crisis they played almost no role in creating. She emphasizes that compensation should not be seen as charity but as a recognition of the injustice faced by vulnerable nations.
The response of young people in Nepal has been a powerful reminder of their role as both victims and leaders in moments of crisis. The formation of the Rasuwa Relief Group, a youth-led initiative mobilizing resources, coordinating support, and sharing verified information, underscores the importance of including youth and the most affected communities in decision-making processes.
In conclusion, Subedi calls for a shift in climate action from mitigation targets and policy conferences to real-time mobilization and inclusion of vulnerable communities. The lessons learned from the Rasuwa disaster must serve as a catalyst for transformative change, ensuring that the voices of those most affected are heard and that the necessary resources are invested to build a more resilient future for Nepal and other climate-vulnerable nations.
