Nepal Floods and Climate Compensation: Loss and Damage Fund Explained for UPSC

Location: The disaster began around Rasuwagadhi in Nepal's Rasuwa district near the Nepal-China border. The affected river system includes the Lhende/Lende Khola, Bhote Koshi and downstream Trishuli-Narayani system. Nepal reported impacts extending through Rasuwa, Nuwakot, Dhading and farther downstream.

Nature of the disaster: A sudden high-energy mass of water, mud, sediment, rock and ice moved downstream. This is important because calling every Himalayan flash flood a GLOF would be scientifically incorrect.

Magnitude: ICIMOD reported that the Trishuli River at Galchhi rose by as much as nine metres within about 30 minutes, demonstrating the extraordinary speed at which a high-mountain cascading hazard can be transformed into a major downstream flood.

Damage pattern: Roads, bridges, settlements and hydropower installations were damaged. The event also affected the strategically important Nepal-China border corridor and required specialised tunnel-rescue operations at several hydropower projects.

Scientific finding: Current evidence suggests no. ICIMOD experts have stated that the August event appears to have been triggered by an ice avalanche rather than a classic glacial lake outburst flood.

What probably happened: Preliminary assessments indicate that an ice-rock avalanche entered the Lhende/Lende valley, may have temporarily obstructed the river and generated a sudden surge containing water, sediment and boulders. USGS independently described the initiating process as a rapid slope failure involving a glacier, although the exact form of the initial collapse remained under investigation.

Prelims caution: “Glacier-related flood” and “GLOF” are not synonyms. A disaster involving glacier ice can occur through ice avalanche, glacier collapse, rock-ice avalanche, landslide-dam failure or other processes without the bursting of a glacial lake.

Definition: A Glacial Lake Outburst Flood (GLOF) is a sudden release of a large quantity of water from a lake associated with a glacier.

Formation of risk: As glaciers retreat, depressions can fill with meltwater. Many Himalayan glacial lakes are held back by moraine—unconsolidated rock and sediment deposited by glaciers.

Trigger: Failure of the containing moraine or ice dam can result from an avalanche, landslide, earthquake, excessive meltwater, overtopping or structural weakening.

Impact: The released water can travel rapidly through narrow mountain valleys while carrying debris and boulders, generating immense destructive force.

ICIMOD notes that moraine-dammed lakes are common in the Hindu Kush Himalaya and that GLOFs have repeatedly caused serious downstream losses.

Ice-rock avalanche: It is the extremely rapid downslope movement of ice, snow and rock from a steep mountain slope.

GLOF: Its defining element is the sudden drainage of a glacial lake.

Debris flow: Once an avalanche mixes with water, soil, sediment and broken rock, it may transform into a fast-moving debris flow.

Temporary dam: Rock and ice may also block a river temporarily. When the barrier fails, it can generate a powerful flash flood even though no pre-existing glacial lake was involved.

The Nepal disaster demonstrates why Himalayan disaster management must monitor entire mountain slopes and river systems rather than only mapped glacial lakes.

Meaning: A cascading hazard occurs when one natural process triggers another, which may then trigger further hazards.

Nepal example: A high-altitude ice-rock failure appears to have generated debris movement, temporary river obstruction or displacement of water, followed by a flash flood that caused major downstream infrastructure failures.

Why mountains are vulnerable: Very steep slopes, glaciers, permafrost, seismicity, narrow valleys, fast-flowing rivers and concentrated infrastructure can interact. A local event high in the mountains can therefore become a basin-scale disaster within hours.

ICIMOD described the Nepal event precisely in these terms: a cryosphere-related event turning into a destructive flood downstream.

Meaning: The cryosphere consists of those parts of Earth where water exists in frozen form, including glaciers, ice sheets, snow cover, permafrost, and river and lake ice.

Importance: Snow and glaciers store freshwater and regulate seasonal river flows. Their bright surfaces also reflect solar radiation through the albedo effect.

Himalayan relevance: Changes in snow, glaciers and permafrost influence water availability, slope stability, floods, ecosystems, agriculture and hydropower across a much larger region than the mountains themselves.

Definition: Permafrost is ground—soil, sediment or rock—that remains at or below 0°C for at least two consecutive years.

Slope stability: Frozen ground can act like a cementing agent within mountain slopes. Thaw can weaken the bonds between rock and sediment, potentially increasing slope instability in susceptible terrain.

Climate connection: The wider Hindu Kush Himalayan cryosphere is experiencing glacier retreat, reduced snow persistence and permafrost degradation as temperatures rise.

Important qualification: Evidence that warming increases regional cryospheric instability does not prove that every individual avalanche or flood was caused by climate change.

Ice reserves: The Hindu Kush Himalaya (HKH) contains the largest concentration of snow and ice outside the polar regions, which is why it is widely called the “Third Pole”.

Geographical extent: The HKH stretches about 3,500 km and covers roughly 4.2 million sq km across Afghanistan, Bangladesh, Bhutan, China, India, Myanmar, Nepal and Pakistan.

Asian water tower: It is associated with major transboundary river systems including the Indus, Ganga, Brahmaputra, Mekong, Salween and others.

Human importance: ICIMOD estimates that roughly 240 million people live in the mountain region and about 1.65 billion people downstream depend directly or indirectly on its resources.

Regional answer: Climate change is clearly transforming the broader Himalayan cryosphere. Rising temperatures, glacier mass loss, changing snowfall and permafrost thaw can alter the probability and consequences of mountain hazards.

Event-specific answer: Scientists have not yet established that anthropogenic climate change caused this particular event. ICIMOD explicitly says that while climate change drives wider cryospheric risks, the specific Nepal disaster cannot yet be directly attributed to warming.

UPSC lesson: Avoid the simplistic statement “climate change caused the Nepal flood”. A scientifically defensible answer is that climate change is altering the background risk environment, while the immediate physical trigger of this particular event requires separate attribution.

Meaning: Climate attribution science examines whether and to what extent human-induced climate change altered the probability or intensity of a particular type of weather or climate event.

Two questions: Scientists may ask whether warming made a hazard more likely or severe. A separate question is whether a particular country's emissions can legally be linked to a particular loss.

Difference from physical trigger: Identifying an avalanche as the immediate trigger and identifying climate change as a factor influencing the probability of such an avalanche are distinct scientific exercises.

This distinction becomes central when demands move from general climate solidarity towards legal “compensation”.

Climate-justice argument: Nepal argues that countries with very low historical emissions are suffering severe impacts from a warming climate generated predominantly by cumulative global greenhouse-gas emissions.

Government position: Foreign Minister Shisir Khanal told diplomats that Nepal contributes a negligible share of global emissions but bears disproportionate consequences of a warming Himalayan region. He confirmed that Nepal had written to the FRLD Board for immediate support.

Diplomatic framing: In media interviews, Khanal used stronger language of “justice and compensation” rather than charity and referred to major emitters. Subsequent official statements emphasised international solidarity, thanked India and other partners, and focused on the multilateral Loss and Damage mechanism.

UPSC caution: Nepal's multilateral request to the FRLD should not automatically be described as a legally established bilateral compensation claim against India.

Basic concept: Loss and damage refers broadly to adverse climate impacts that occur despite mitigation and adaptation efforts, including impacts that cannot be completely avoided.

Economic losses: Destruction of houses, crops, roads, power plants, businesses and other assets can be valued monetarily.

Non-economic losses: Loss of life, health, cultural heritage, ecosystems, territory, identity or displacement may be extremely serious even when they cannot easily be expressed in money.

Extreme and slow-onset events: UNFCCC's loss-and-damage framework covers both sudden disasters such as extreme weather events and slow-onset processes such as sea-level rise and other gradual climate impacts.

Mitigation: Actions that reduce the causes of climate change—for example, cutting greenhouse-gas emissions or increasing carbon sinks.

Adaptation: Actions that reduce vulnerability to expected climate impacts—for example, flood-resistant infrastructure, drought-resistant agriculture or early-warning systems.

Loss and damage: Measures addressing harm that occurs despite, or beyond the limits of, mitigation and adaptation.

Simple sequence: Mitigation tries to prevent warming; adaptation tries to live more safely with unavoidable impacts; loss-and-damage mechanisms respond to residual harm that still occurs.

Overlap: They are not completely separate. Effective mitigation and adaptation reduce future loss and damage.

Warsaw International Mechanism: COP19 established the Warsaw International Mechanism for Loss and Damage (WIM) in 2013. It became the principal UNFCCC mechanism for enhancing knowledge, coordination, action and support on loss and damage.

Paris Agreement: Article 8 of the Paris Agreement formally recognised the importance of averting, minimising and addressing loss and damage.

Santiago Network: COP25 established the Santiago Network in 2019 as part of the WIM to catalyse technical assistance for vulnerable developing countries.

Dedicated Fund: COP27 established new funding arrangements and the Fund for responding to Loss and Damage.

Operationalisation: COP28 operationalised the Fund and established its governance framework.

The chronology is therefore: WIM → Paris Article 8 → Santiago Network → FRLD.

Purpose: The Fund for responding to Loss and Damage (FRLD) assists developing countries that are particularly vulnerable to adverse climate effects in responding to economic and non-economic loss and damage.

Coverage: Its mandate includes both extreme-weather events and slow-onset climate impacts.

Institutional status: It is an entity entrusted with operating part of the UNFCCC Financial Mechanism and also serves the Paris Agreement. It functions under the guidance of, and is accountable to, the COP and CMA.

Governance: The Fund has a Board containing representatives of developed and developing-country constituencies. The Philippines hosts the Board, while the World Bank serves as interim trustee under the arrangements agreed during its operationalisation.

Eligibility: All developing countries considered particularly vulnerable to the adverse effects of climate change are eligible under the Fund's current start-up arrangements.

Country-led approach: Countries identify their own loss-and-damage priorities and submit funding requests according to the Fund's procedures.

Possible uses: Funding may address economic and non-economic losses and can support recovery, reconstruction, displacement-related needs and other priority gaps. The FRLD's current guidelines also allow requests relating to climate-related losses that have already occurred when needs remain unresolved.

Start-up window: The Barbados Implementation Modalities (BIM) are the FRLD's initial operational funding framework for testing interventions and learning before development of its longer-term system.

Allocation: The Board initially set aside USD 250 million for 2025-26.

Vulnerable-country floor: At least 50% of this amount has been reserved as a minimum floor for Small Island Developing States (SIDS) and Least Developed Countries (LDCs).

Broader eligibility: This does not mean that only SIDS and LDCs are eligible; all particularly vulnerable developing countries can seek access under the modalities.

Pledges: Official FRLD data record USD 822.06 million pledged by 27 partners as of 15 March 2026. Twenty-five partners had signed contribution agreements according to the latest funding page.

Pledge versus available finance: A pledge is a commitment. It should not automatically be treated as cash already available for immediate disbursement.

Scale problem: Global losses from climate impacts can reach many billions of dollars from a single major disaster. The Fund's current capitalisation is therefore modest relative to potential global demand.

UPSC Mains issue: Loss-and-damage negotiations are increasingly moving from establishing institutions to the more difficult question of ensuring predictable, adequate and accessible finance.

No automatic liability: This is one of the most important distinctions in the present controversy.

Paris compromise: The decision adopting the Paris Agreement expressly states that Article 8 does not provide a basis for liability or compensation.

FRLD character: The Fund is a multilateral climate-finance mechanism. Receiving finance does not by itself establish that a particular donor State legally caused a particular disaster.

Political terminology: Vulnerable countries and climate-justice advocates frequently use “compensation” in the wider ethical or political sense of polluters helping those who contributed least to the crisis.

Legal terminology: In international law, compensation as reparation normally requires a wrongful act, injury and the necessary causal connection.

No: The position is more nuanced.

Paris Agreement itself: Article 8 cannot be used as a direct treaty basis for liability or compensation because of the accompanying COP decision.

General international law: Separate international-law obligations—including customary duties concerning environmental harm—can still be relevant. This became much more important after the ICJ's 2025 climate advisory opinion.

Two legal tracks: The FRLD represents cooperative multilateral climate finance. State responsibility and reparation are questions of international law. They should not be conflated.

Advisory Opinion: In Obligations of States in respect of Climate Change, the ICJ examined States' obligations under climate treaties, customary international law, the law of the sea and human-rights law.

State responsibility: The Court held that internationally wrongful breaches of applicable climate-related obligations can produce ordinary consequences of State responsibility, including cessation, guarantees of non-repetition and, where legally established, reparation.

Causation: For compensation, an injured State would still need to demonstrate a “sufficiently direct and certain causal nexus” between the wrongful act and the injury. Climate causation must be assessed in the circumstances of the particular case.

Nepal implication: The opinion strengthens the legal significance of climate obligations but does not automatically establish that India, China, the United States or another individual country legally owes Nepal compensation for this flood.

Accumulated emissions: Climate change results from greenhouse gases emitted by numerous countries and actors over long periods.

Multiple causes of disasters: A mountain catastrophe may result from combinations of geology, topography, glacier dynamics, precipitation, earthquakes, infrastructure exposure, land use and climate conditions.

Two-stage problem: First, science must determine whether climate change materially affected the relevant hazard. Second, a legal process would need to connect the injury sufficiently to a State's breach of an applicable obligation.

ICJ position: The diffuse nature of climate change does not make responsibility legally impossible, but causation still has to be established in concreto—in the particular case.

Core idea: Climate justice examines climate change through the distribution of responsibility, vulnerability, capacity and impacts rather than treating the crisis only as a scientific problem.

Historical emissions: Greenhouse gases remain in the atmosphere for long periods. Cumulative historical emissions therefore matter when discussing responsibility for the current stock of warming gases.

Unequal impacts: Countries with relatively low historical emissions may nevertheless be highly vulnerable because of geography, poverty, limited fiscal capacity or reliance on climate-sensitive sectors.

Nepal's argument: A small Himalayan economy argues that it should not be forced to finance immense reconstruction costs primarily from its own limited resources when the underlying global warming problem is largely produced beyond its borders.

CBDR-RC: The principle of Common but Differentiated Responsibilities and Respective Capabilities recognises that climate protection is a common responsibility but that States' obligations and expectations must reflect differing historical contributions, capacities and national circumstances.

UNFCCC logic: Developed economies industrialised earlier and account for a large share of historical emissions, while developing countries still face poverty eradication and developmental requirements.

Paris formulation: The Paris Agreement is to be implemented to reflect equity and CBDR-RC “in the light of different national circumstances”. The ICJ also identified CBDR-RC and equity as relevant interpretative principles in climate law.

India's importance: This is a central principle of India's climate diplomacy.

Annual emissions: They show how much a country emits in a particular year.

Cumulative emissions: They measure the historical accumulation of emissions over a much longer period and are particularly relevant because carbon dioxide remains in the climate system for long periods.

Per-capita emissions: These divide emissions by population and illuminate differences in individual-level emission intensity.

Development dimension: India is presently among the world's largest annual emitters in absolute terms because of its population and economic scale, but its historical and per-capita emissions remain substantially lower than those of many industrialised economies.

UPSC approach: A balanced climate-justice answer should distinguish annual, cumulative and per-capita emissions rather than selectively using only one measure.

Immediate response: India treated the disaster first as a humanitarian emergency. Prime Minister Narendra Modi conveyed condolences to Nepal's Prime Minister Balendra Shah and offered all possible humanitarian assistance.

Operational support: Nepal's official briefing records Indian specialised tunnel-rescue teams working at Langtang and Chilime as well as Indian forensic assistance.

Climate diplomacy: In response to Nepal's “justice” remarks, India's Ministry of External Affairs described climate change as a common challenge and reiterated India's established position that developed countries should lead in emissions reduction and provide finance and technology to developing countries.

Balanced approach: India can support Nepal's demand for stronger international climate finance while maintaining the distinction between the differentiated responsibility of historically industrialised economies and the development needs of countries such as India.

Shared mountains: India and Nepal are both part of the Hindu Kush Himalayan ecological system.

Shared rivers: Several rivers originating or flowing through Nepal ultimately enter the Ganga basin in India.

Downstream risk: High-altitude floods can cross administrative and national boundaries very rapidly. Early information from upstream areas can therefore save lives downstream.

Existing mechanisms: India and Nepal already cooperate through mechanisms such as the Joint Team on Flood Forecasting (JTFF), Joint Committee on Kosi and Gandak Projects, Joint Committee on Inundation and Flood Management, and Joint Committee on Water Resources.

Future requirement: Traditional river-flood cooperation increasingly needs to incorporate glacier collapse, GLOFs, permafrost degradation, landslide dams and other emerging cryosphere hazards.

Geographical advantage: Himalayan rivers have steep gradients and large hydropower potential.

Geographical risk: The same steep valleys are exposed to landslides, sediment flows, flash floods, avalanches and seismic activity.

Cascade vulnerability: Roads, tunnels, dams, transmission lines and workers' settlements may be concentrated within narrow river corridors. One upstream event can therefore damage several projects successively.

Changing baseline: Infrastructure designed using historical hydrological conditions may become inadequate if the frequency or magnitude of extreme events changes.

Policy implication: New Himalayan infrastructure should be based on multi-hazard assessments rather than project-by-project engineering alone.

Hazard versus disaster: A natural hazard becomes a disaster when it interacts with exposed people and vulnerable assets.

Exposure: More roads, hydropower projects, buildings, tourism facilities and settlements in unstable valleys increase the amount of infrastructure that can be damaged.

Vulnerability: Poor siting, weak slope stabilisation, inadequate drainage, insufficient evacuation routes or failure to account for extreme events can amplify losses.

Key distinction: Infrastructure need not cause an avalanche for infrastructure policy to influence the scale of resulting loss.

This is why disaster-risk reduction considers hazard × exposure × vulnerability, rather than hazard alone.

Risk-informed planning: Roads, dams, tunnels, settlements and tourism infrastructure must incorporate glacier, avalanche, landslide, seismic and extreme-flood risks.

Cumulative assessment: Environmental assessment should consider the combined effect of multiple projects located within the same river basin.

Monitoring: High-resolution satellite data, automatic weather stations, river gauges, seismic sensors, glacier monitoring and remote sensing should be integrated into a common warning system.

Last-mile warning: A warning has little value unless it reaches villages, workers, pilgrims and local administrations in time and in an actionable form.

Resilient infrastructure: Bridges, power plants and communications must be designed for plausible future extremes, not only historical averages.

Transboundary geography: Glaciers, rivers, weather systems and avalanches do not follow political borders.

Information asymmetry: A hazard can originate in one country but strike communities in another before national authorities have sufficient information.

Shared monitoring: India, Nepal, Bhutan, China and other HKH countries would benefit from rapid exchange of hydrological, glaciological, seismic and satellite-derived hazard information.

Scientific institution: ICIMOD is particularly important because it is an intergovernmental knowledge and research organisation focused on the Hindu Kush Himalaya.

Strategic lesson: Climate security in the Himalayas is increasingly linked with science diplomacy.

Economic: Destroyed houses, bridges, hydropower facilities, roads, shops, agricultural assets and reconstruction expenditures can be assigned monetary values.

Non-economic: Deaths, family separation, psychological trauma, displacement, loss of community networks, cultural sites and ecosystem services may be partly or wholly impossible to price.

Policy challenge: Conventional disaster accounting tends to capture damaged infrastructure better than non-economic loss.

FRLD relevance: Its mandate explicitly includes both economic and non-economic loss and damage.

Disaster borrowing: A vulnerable developing country may have to borrow heavily to rebuild infrastructure after a major disaster.

Debt-climate trap: Repeated borrowing for climate disasters can increase public debt, reduce fiscal space and leave fewer resources for education, health and development.

Justice argument: Vulnerable countries argue that rebuilding damage caused substantially by a global environmental problem should not push them into deeper debt.

Funding implication: This strengthens demands for grant-based and highly concessional loss-and-damage finance rather than excessive reliance on conventional loans.

Insufficient capital: USD 822.06 million in total pledges is small compared with the potentially enormous and recurring global requirements.

Access speed: Disaster-struck countries need money rapidly, while multilateral funding mechanisms often require proposals, verification, Board approval and implementation arrangements.

Predictability: Voluntary contributions make long-term resource availability uncertain.

Attribution problem: Governments may politically describe disasters as climate-related even before event-attribution science is complete.

Equity question: Negotiators continue to disagree over who should contribute, how much historical responsibility should matter and whether large developing-country emitters should also contribute.

Coordination: Humanitarian aid, adaptation finance, insurance, development finance and loss-and-damage funding can overlap unless their roles are clearly coordinated.

GS1 Geography: Himalayan cryosphere, glaciers, rivers, permafrost, avalanches, GLOFs and geographical vulnerability.

GS2 International Relations: India-Nepal relations, neighbourhood policy, transboundary rivers, international institutions and climate diplomacy.

GS3 Environment: Climate change, climate finance, CBDR-RC, loss and damage, disaster-risk reduction, resilient infrastructure and environmental impact assessment.

GS3 Disaster Management: Early warning, cascading hazards, exposure, vulnerability, reconstruction and regional cooperation.

Essay dimension: Climate justice raises a larger question—whether those least responsible for a global environmental crisis should carry the greatest human and financial burden of its consequences.

Complete a scientifically rigorous Post-Disaster Needs Assessment in Nepal and maintain a clear distinction between immediate physical causes, climate-risk amplification and formal climate-event attribution.

Develop an emergency-access pathway within the FRLD so that catastrophic events do not face prolonged financing delays while reconstruction needs become urgent.

Build a substantially larger and more predictable pool of grant-based loss-and-damage finance, particularly for highly vulnerable and fiscally constrained countries.

Integrate glacier, permafrost, avalanche, landslide and river monitoring rather than treating GLOFs as the only Himalayan cryosphere hazard.

Expand cross-border early-warning systems and real-time sharing of hydrological, seismic and remote-sensing data among Himalayan countries.

Upgrade existing India-Nepal mechanisms such as JTFF and JCIFM to systematically incorporate emerging cryosphere and cascading-hazard risks.

Make Himalayan infrastructure planning multi-hazard and basin-wide, including cumulative impact assessments for hydropower, highways, tunnels and settlements.

Strengthen local last-mile communication, evacuation routes, resilient telecom networks and community-based disaster preparedness.

Keep climate justice aligned with CBDR-RC: vulnerable countries require support, while responsibility should reflect historical contribution, capability and development needs rather than relying only on current annual emissions.

Maintain the legal distinction between cooperative climate finance through the FRLD and judicial compensation under the law of State responsibility, while recognising the growing importance of international climate jurisprudence.

Promote regional “science diplomacy” through ICIMOD and other institutions so that shared Himalayan ecosystems become an area of cooperation even when broader geopolitical relations are difficult.
