BackgroundCore Concept

Background

The Himalayas are geologically young fold mountains formed by the collision of the Indian and Eurasian tectonic plates. This origin gives the range its defining characteristics: deep gorges, steep gradients, and rivers that shift course rapidly. These features also make the Himalayas structurally unstable. Rock layers are fractured and compressed, and glaciers sit above valleys that drop thousands of metres within short horizontal distances. The Bhotekoshi River valley, connecting Nepal's Rasuwa district to Tibet's Gyirong area, is one of the steepest such corridors in the entire range. The river descends from over 5,000 m at the Tibet border to around 600 m near Kathmandu within roughly 80 km.

Himalayan landslides and floods differ fundamentally from those in the Western Ghats. In the Himalayas, the primary drivers are young fragile geology, high seismic activity, steep slopes, and the presence of glaciers and glacial lakes. In the Western Ghats, landslides are driven mainly by intense seasonal rainfall on laterite soils and deforestation on relatively stable, older rock formations. Himalayan events tend to be sudden, high-velocity, and triggered by geophysical processes such as seismic shocks or ice-rock avalanches. This distinction matters for disaster preparedness planning.

Climate change has added a new layer of risk. The Himalayan region is warming at roughly twice the global average rate. Glaciers are retreating faster, leaving behind unstable glacial lakes held by loose moraine dams. When these dams breach, the resulting Glacial Lake Outburst Floods (GLOFs) release enormous volumes of water and debris within minutes. The Uttarakhand glacial burst of 2013, which destroyed areas around the Kedarnath temple and killed thousands, is a landmark example of how glacial hazards translate into catastrophic downstream consequences.

The Topic Explained

A Glacial Lake Outburst Flood (GLOF) occurs when a natural dam holding back a glacial lake fails suddenly. The dam can be made of ice or loose moraine material. Failure can be triggered by an earthquake, an ice or rock avalanche falling into the lake, or simply by the gradual weakening of the moraine wall as the glacier retreats. Once the dam fails, the stored water rushes downstream as a fast-moving wall of water and debris. Narrow mountain valleys concentrate this energy, making GLOFs far more destructive per unit of water than floods on plains.

The climate justice dimension of GLOFs is significant. Nepal contributes less than 0.1 per cent of global greenhouse gas emissions, yet it absorbs a disproportionate share of climate-driven disaster risk. This asymmetry is the core argument behind the principle of Common But Differentiated Responsibilities and Respective Capabilities (CBDR-RC), enshrined in the UNFCCC (1992). The Paris Agreement (2015) acknowledged the special vulnerability of mountainous and small states. …
