Nepal floods expose climate finance delay: GCF took seven years to approve glacier-risk project while lenders backed hydropower in vulnerable basin
On 26 August 2026, a cascading flood of ice, rock, mud, and debris struck Nepal's Bhote Koshi and Trishuli river basins, damaging settlements, infrastructure, and hydropower projects; more than 350 people were rescued from hydropower tunnels.
It emerged that the Green Climate Fund (GCF) took seven years to approve a glacier flood resilience project for Nepal, from proposal in February 2018 to approval in July 2025, with implementation beginning only in March 2026 — after the flood had already struck.
During the same period, international lenders financed multiple large hydropower projects in the same vulnerable river basins, including the Upper Trishuli-1 and Trishuli 3A projects.
An independent panel had recommended a comprehensive climate resilience assessment for the basin in 2025, which remains incomplete.
Green Climate Fund (GCF)
The Green Climate Fund is the largest dedicated multilateral climate finance mechanism, established to help developing countries with mitigation and adaptation, serving as an operating entity of the Financial Mechanism of the UNFCCC and the Paris Agreement.
Key Details
- Established under the 2010 Cancún Agreements at COP16; headquartered in Songdo, Incheon, South Korea (since December 2013).
- Governed by a 24-member Board, equally split between developed and developing country representatives, co-chaired by one member from each group; funding decisions are typically made by consensus.
- India has a national designated authority for the GCF and an accredited entity structure to access funds; a GCF-related executive committee chaired by the Secretary, Ministry of Environment, Forest and Climate Change, was constituted in 2015 to coordinate India's engagement.
The seven-year delay in approving Nepal's glacier-risk project (proposed 2018, approved 2025) illustrates a structural criticism of the GCF — that its multi-stage approval process is too slow for climate-vulnerable, disaster-prone regions like the Himalayas, where risk materialises faster than funding can be disbursed.
Glacial Lake Outburst Floods (GLOFs) and Himalayan Disaster Risk
A Glacial Lake Outburst Flood occurs when a glacial lake's natural dam — made of moraine or ice — fails suddenly, releasing a massive volume of water and debris downstream; climate warming increases GLOF risk by accelerating glacier melt and lake formation across the Himalayas.
Key Details
- The Himalayan region, spanning India, Nepal, Bhutan, and China, has thousands of glacial lakes; several hundred are classified as posing significant outburst risk.
- India's National Disaster Management Authority runs the National Glacial Lake Outburst Flood Risk Mitigation Programme, with an allocation of Rs 150 crore, focused on around 195 high-risk lakes across Himachal Pradesh, Uttarakhand, Sikkim, Arunachal Pradesh, Jammu & Kashmir, and Ladakh.
- The Chamoli disaster of February 2021, caused by a rock-ice avalanche triggering a flash flood on the Rishiganga and Dhauliganga rivers in Uttarakhand, is a comparable Indian precedent that similarly damaged hydropower infrastructure.
The Nepal floods are attributed to cascading ice/rock/debris flow consistent with GLOF-type dynamics in a Himalayan basin; India's own GLOF mitigation programme reflects the same transboundary risk that the Nepal event highlights, given the shared Himalayan glacial system.
Hydropower Development in Fragile Himalayan River Basins
Hydropower projects in the Himalayas are financed by a mix of multilateral development banks, bilateral lenders, and export credit agencies, and are increasingly scrutinised for locating infrastructure in seismically active, GLOF-prone basins without adequate cumulative risk assessment.
Key Details
- The Trishuli river basin alone hosts more than 36 hydropower projects; the Upper Trishuli-1 project (214 MW, about USD 647 million) was financed by a consortium including the Asian Development Bank, the International Finance Corporation, British International Investment, South Korean development banks, the Netherlands' FMO, and the OPEC Fund, with the consortium closing about USD 453 million in debt financing in November 2019.
- The Trishuli 3A project was financed through a USD 149 million concessional loan from China's Export-Import Bank, illustrating how both Western multilateral lenders and Chinese state banks are active in the same river basin.
- Cumulative environmental and disaster-risk assessment — accounting for seismicity, GLOF risk, and ecosystem impacts across multiple projects in one basin — is frequently flagged as inadequate compared to project-by-project Environmental Impact Assessments.
The core criticism raised after the floods is a mismatch in risk-adjusted capital allocation — large sums moved quickly into hydropower project financing in the same basin where a comparatively small glacier-risk adaptation grant took seven years to clear approval, despite both being financed by overlapping sets of international development institutions.
- Nepal flood event: 26 August 2026, Bhote Koshi and Trishuli river basins; over 350 people rescued from hydropower tunnels.
- GCF glacier flood resilience project (FP272): proposed 14 February 2018; approved 3 July 2025; implementation began 12 March 2026, running through 12 March 2033; valued at USD 49.9 million (~Rs 473.83 crore); aims to protect an estimated 2.4 million people from GLOF risk.
- Upper Trishuli-1: 214 MW, ~USD 647.4 million project; ~USD 453 million in debt financing closed November 2019.
- Trishuli 3A: financed via a USD 149 million concessional loan from China's Export-Import Bank.
- Trishuli basin hosts over 36 hydropower projects.
- GCF established 2010 (Cancún Agreements); headquartered in Songdo, South Korea; 24-member Board.
