 The paper discusses the importance of mountains as sources of fresh water for our world, but their role in global water resources could be significantly altered by climate change. The authors examine 11 case study regions to provide a global overview and identify research gaps and formulate recommendations for research, management, and policy. They focus on highland lowland areas and identify research priorities such as precipitation, snow water equivalent, soil parameters, evapotranspiration, sublimation, groundwater, enhanced warming, and feedback mechanisms. The paper recommends advancements in the management of mountain water resources under climate change through better interaction between research, water resources management, and policy, as well as improved knowledge exchange between managers and researchers. The authors conclude that effective management of mountain water resources requires more detailed regional studies and reliable scenario projections, and that research on mountain water resources must become more integrative by linking relevant disciplines.
