AndesPlus is a project within the framework of the Adaptation to the Impacts of Rapid Glacier Retreat in the Tropical Andes Project (PRAA) of the Andean Community of Nations (CAN) and the World Bank. The PRAA project seeks to reinforce resilience of local ecosystems and economies vis-à-vis the impacts caused by glacier retreat in the Tropical Andes through the implementation of pilot activities evidencing costs and benefits of adaptation to climate change in the basins selected in Bolivia, Ecuador, and Peru.

Cost-Benefit Assessment of Adaptation Measures in Switzerland under Climate Uncertainties

The economic evaluation of different adaptation options is an important tool to help policy-makers setting priorities in the decision-making process. However, decision preferences face considerable uncertainties in the face of unpredictable climate events, least because the climate system is a highly complex system characterized by interactions between physical processes and human behaviour. In this project, sponsored by the Climate Division of the Bundesamt für Umwelt (BAFU), we developed a dynamic, stochastic model and used dynamic programming to explore the optimal adaptation decisions under uncertainty in face of uncertain impacts from climate change such as debris flows and flooding in the region of Grimsel/Guttannen (Switzerland).

Intergovernmental Panel on Climate Change

The Intergovernmental Panel on Climate Change (IPCC) is a scientific body under the auspices of the United Nations and regularly assesses the scientific information worldwide, as relevant to a broad range of subjects on climate change. IPCC is an intergovernmental body, with 195 member states. Governments review IPCC reports and endorse them, thus acknowledging the authority of the scientific content. As such, IPCC can be seen as an institution at the science-policy interface.

New lakes in de-glaciating high-mountain areas: climate-related development and challenges for sustainable use

In the Alps, melting glaciers rapidly lead to the creation of new lakes. This entails new opportunities and risks. We need to know where and when new lakes are formed, what their properties are, whom they belong to and who is responsible for them.

Slope Stability and Glacier Lake Monitoring

Among glacier hazards, glacier lake outburst floods (GLOFs) are especially devastating and represent the glacial threat with the farthest potential reach, up to hundred kilometers and more downstream of the glacier lake that burst out. Typically, glacier lake outbursts are a part of complex chain reactions and process interactions, for instance when sudden slope failures above a lake cause impact waves that trigger destabilization of a lake dam that would otherwise remained stable. In fact, severe disasters were caused in the past by outbursts from glacial lakes in various high-mountain regions of the world, including the Andes, the Himalayas, Caucasus and Central Asia, North America, and the European Alps.
