![]() Asia’s shrinking glaciers protect large populations from drought stress. Exceptional increases in fluvial sediment fluxes in a warmer and wetter High Mountain Asia. Global-scale hydrological response to future glacier mass loss. Glacier mass change in High Mountain Asia through 2100 using the open-source Python Glacier Evolution Model (PyGEM). in The Hindu Kush Himalaya Assessment (eds Wester, P. in Special Report on the Ocean and Cryosphere in a Changing Climate (eds Pörtner, H. Recent third pole’s rapid warming accompanies cryospheric melt and water cycle intensification and interactions between monsoon and environment: multidisciplinary approach with observations, modeling, and analysis. ![]() Elevation-dependent warming in mountain regions of the world. Increasing dependence of lowland populations on mountain water resources. Viviroli, D., Kummu, M., Meybeck, M., Kallio, M. Importance and vulnerability of the world’s water towers. Here we recommend forward-looking design and maintenance measures and sustainable sediment management solutions that can help transition towards climate change-resilient dams and reservoirs in High Mountain Asia, in large part based on improved monitoring and prediction of compound and cascading hazards. The result is large amounts of sediment being mobilized that can fill up reservoirs, cause dam failure and degrade power turbines. ![]() Ranging in severity and the pace of change, these processes include glacial retreat and detachments, permafrost thaw and associated landslides, rock–ice avalanches, debris flows and outburst floods from glacial lakes and landslide-dammed lakes. However, these projects are vulnerable to a complex set of interacting processes that are destabilizing landscapes throughout the region. The construction of more reservoirs designed to regulate streamflow and produce hydropower is a critical part of strategies for adapting to these changes. ![]() Global warming-induced melting and thawing of the cryosphere are severely altering the volume and timing of water supplied from High Mountain Asia, adversely affecting downstream food and energy systems that are relied on by billions of people. ![]()
