| Zusammenfassung |
Mountains are essential sources of freshwater for our world, but their role
in global water resources could well be significantly altered by climate
change. How well do we understand these potential changes today, and what
are implications for water resources management, climate change adaptation,
and evolving water policy? To answer above questions, we have examined 11
case study regions with the goal of providing a global overview, identifying
research gaps and formulating recommendations for research, management and
policy.
After setting the scene regarding water stress, water management capacity
and scientific capacity in our case study regions, we examine the state of
knowledge in water resources from a highland-lowland viewpoint, focusing on
mountain areas on the one hand and the adjacent lowland areas on the other
hand. Based on this review, research priorities are identified, including
precipitation, snow water equivalent, soil parameters, evapotranspiration
and sublimation, groundwater as well as enhanced warming and feedback
mechanisms. In addition, the importance of environmental monitoring at high
altitudes is highlighted. We then make recommendations how advancements in
the management of mountain water resources under climate change could be
achieved in the fields of research, water resources management and policy as
well as through better interaction between these fields.
We conclude that effective management of mountain water resources urgently
requires more detailed regional studies and more reliable scenario
projections, and that research on mountain water resources must become more
integrative by linking relevant disciplines. In addition, the knowledge
exchange between managers and researchers must be improved and oriented
towards long-term continuous interaction. |
