Climate Vulnerability in Asia’s High Mountains

The report examines the vulnerability of Asia's High Mountains (AHM) to climate change, highlighting risks from glacial melt, extreme weather, and water scarcity. It details the varying responses of mountain ranges—such as the retreat of most glaciers in the Hindu Kush-Himalaya versus stability in the Karakorum—and analyzes the resulting threats to human health, agriculture, and infrastructure. The document evaluates current adaptation strategies, including livelihood diversification and community-based water management, while identifying critical data gaps in permafrost and groundwater storage. It concludes with recommendations for regional cooperation in disaster risk management and the synchronization of national and local climate policies.

• Asia's High Mountains (AHM) are highly vulnerable to climate shifts due to a heavy dependence on seasonal rainfall and glacial runoff, as well as a lack of resources in many communities to respond to rapid changes.
• Extreme weather events in AHM can have a disproportionate impact on water resources and erosion; for instance, a single extreme event can account for 10% of a catchment's annual water intake, and 50% of yearly rainfall in monsoon regions can occur within 10 days.
• Glacial Lake Outburst Floods (GLOFs) and Landslide Lake Outburst Floods (LLOFs) are continuing risks throughout AHM, often triggered by avalanches, earthquakes, storms, or seasonal melt water breaching weakly bound sediment dams.
• Increased precipitation intensity leads to higher sediment flux in rivers, which degrades water quality and damages hydropower infrastructure through turbine abrasion and reservoir infilling.
• Climate change impacts human health in AHM by extending the range of vector-borne diseases like malaria and reducing food security, which lowers the population's capacity to resist such diseases.
• Glacial responses vary significantly by range: while most glaciers in the Hindu Kush-Himalaya (HKH) have retreated, those in the Karakorum and Pamir Ranges showed mass gain between 1999 and 2011.
• In the Indus Basin, snowmelt and glacial melt are primary water drivers, contributing 34% of the total hydrological budget, though projections suggest a steep decline in water availability as small glaciers disappear.
• The Ganges Basin is less dependent on glacial melt, with only 8.7% of discharge related to snow and ice melt, and is primarily driven by summer monsoon rains.
• Livelihood diversification, such as integrating vegetable crops into farm rotations or diversifying livestock herds, has proven effective in increasing community resilience to climate variability.
• Structural flood interventions, such as embankments, can sometimes lead to maladaptation by reducing a community's willingness to adapt and creating more extreme floods when they breach.
• There are significant data gaps in AHM regarding the effects of black carbon, melting permafrost, and transient groundwater storage on water regimes.
• National climate policies in AHM countries often fail to translate into provincial or city-specific actions, and many countries cite a lack of resources as a primary barrier to implementation.
