Description: Das Projekt "Climate Change Adaptation and Disaster Risk Reduction related to deglaciation in the Andes of Cusco and Ancash, Peru" wird vom Umweltbundesamt gefördert und von Universität Zürich, Geographisches Institut durchgeführt. High-mountain environments with snow and ice are particularly sensitive to climatic change. Rapid glacier retreat with formation of new lakes, degradation of permafrost with large destabilized mountain slopes and critical changes in hydrological regimes and water supply are key challenges for local high-mountain communities and adjacent lowland regions. The glaciated mountain ranges in the Regions of Ancash and Cusco in Peru are especially vulnerable to, and affected by impacts from climate change. Local communities and cities often exist directly within the reach of major hazard potentials such as lake outburst floods (aluviones), mud/debris flows (huaycos) or large rock/ice avalanches. People and institutions of the Cordilleras in Peru - particularly in the Cordillera Blanca - have long-standing experience with living and adapting to changing environmental conditions. As early as in the 1940s, for instance, risk reduction measures were undertaken at unstable glacier lakes. However, current changes are rapidly evolving beyond historical experience and pose increasingly large challenges to local communities and institutions. The responsible institutions at local, regional and national levels therefore urgently demand for knowledge exchange, international cooperation and support to develop the capacities to adequately respond to corresponding current and future challenges. The Regions of Ancash and Cusco are foremost examples of the challenges related to climate change, which provinces and cities have to cope with. For example, on 11 April 2010 a rock-/ice avalanche from the top of Hualcán mountain in the Cordillera Blanca entered a glacier lake formed during the past few decades and caused a flood wave that impacted downstream areas and caused a debris flow reaching the city of Carhuaz. Fortunately, nobody was seriously injured this time. However, similar events during the past decades have killed thousands of people in this region. Another recent example is the hyperconcentrated flow of 24 January 2010 that originated from a pro-glacial lake and destroyed parts of the village of Santa Teresa in the Department of Cusco while the original trigger factors are still unclear.
