From Climate Finance to Climate Resilience: A Critical Review of Climate Change, Cryosphere Hazards, Disaster Risk Reduction and Financing Lessons from the 2026 Bhotekoshi Flash Flood in Nepal

Abstract

Nepal’s Himalayan region is facing growing threats from climate change melting glaciers shifting snow patterns and unpredictable rainfall. As the ice melts and the weather changes the mountains become more unstable. At the time more people are living and building homes and roads in areas that are naturally at risk. This mix of human factors is creating a much more dangerous situation, for the communities that live in these valleys. The catastrophic flash flood and debris- flow event that struck Bhotekoshi and downstream areas on 26 August 2026 provides an opportunity to examine these interconnected risks. Importantly it raises questions about whether existing climate-finance and disaster-risk-financing systems are sufficiently prepared to reduce such risks. The Bhotekoshi flood has been devastating, in the context. It has brought the nation to a state of distress.

This paper presents a review of the relationship between climate change cryosphere hazards, disaster risk reduction, climate finance and long-term resilience in Nepal. The study uses the 2026 Bhotekoshi disaster as a contemporary case lens to explore how climate change drives cryosphere hazards that increase disaster risk reduction challenges. The authors also discuss how climate finance can build long-term resilience in Nepal. Peer-reviewed literature was examined with evidence, from international climate-finance institutions, disaster-management agencies and scientific assessments. GLOF, flash floods and cascading mountain hazards; The review focuses on five themes: (1) climate and cryosphere change; (2) GLOF, flash-flood and cascading mountain hazards; (3) climate adaptation and disaster-risk reduction; (3) climate adaptation and disaster risk reduction; (4) climate and disaster risk financing; and (5) post disaster recovery, loss and damage and Build Better.

The review points out that Nepal has taken steps in creating climate and disaster-risk groups and in getting international adaptation money. The Green Climate Fund programme that tackles glacier lake outburst floods and climate-driven flooding marks a move, toward planning and investing in adaptation before disasters hit. However, the research also shows that there are still differences between what happens during disasters and the money that is available to deal with them. There is no use of financial tools that come before a disaster happens. Also, there are problems with how different organizations work. It is hard to get climate money down to the level. The Bhotekoshi disaster shows how hard it is to handle disasters that happen one, after another. These kinds of disasters can involve glaciers, rocks, dirt and rivers all at the time.

The paper says that Nepal problem is not about getting more money for climate issues but about making sure the money leads to real reductions in risks. An idea called the Climate Finance–DRR–Resilience Nexus is suggested. This idea connects things like watching for dangers giving warnings getting communities ready building strong buildings having money set aside before a disaster responding quickly when something happens rebuilding after making things better, than before and planning for the future. The study ends by saying Nepal needs to stop reacting after disasters happen and instead start planning ahead. This means looking at risks having money ready stopping problems before they get bad getting ready acting early rebuilding in a strong way and thinking about the long term.
