Water resources in high mountains play a fundamental role for societies and ecosystems. A growing number of studies assesses recent and future impacts in snow and ice related river runoff due to climate change and socioeconomic shifts in major mountain ranges and adjacent downstream areas. In parallel, scholars, engineers and decision-makers have come up with adaptation strategies to reduce existing and projected water supply-demand deficits. The recently published 5th Assessment Report of the IPCC has emphasized the fundamental importance of the risk-adaptation nexus for the development of adaptation strategies to reduce and manage future climate risks. However, comprehensive analyses of risks related to water resources considering climate change within multi-dimensional drivers across different scales are complex and often missing in climate sensitive mountain regions where data scarcity represents important limitations.This collaborative project will address this challenge by combining internationally leading expertise from geographical (GIUZ, University of Zurich), hydrological (IWS, University of Stuttgart) and social sciences (ZIRIUS, University of Stuttgart). This research, conducted in strong collaboration with local partners, focuses on the highly glaciated Santa and Vilcanota river basins in Peru, extending from the Andes to dry coastal downstream areas where water risks are of highest relevance. It proposes the coupling of hydro-climatic (water supply) and socioeconomic (water demand) data in an integrated water balance modelling framework, as a basis to develop scenarios for the future with local stakeholders, and iteratively analyse water risks and adaptation strategies based on the IPCC and IRGC risk governance frameworks. The project will be organized in five Work Packages (WP). WP1, led by IWS, aims at developing spatially and temporally consistent series of high-resolution hydro-climatic data (observed and projected), using innovative interpolation, gap-filling and climate downscaling methods. WP2 (led by GIUZ) undertakes a comprehensive analysis and quantification of water demand and related drivers as observed in the case study regions. Based on the inputs from WP1 and WP2, WP3 (led by ZIRIUS) develops consistent scenarios by combining hydro-climatic and socioeconomic drivers within a stakeholder process, and using a Cross-Impact Balance Analysis (CIB) approach. Afterwards, WP4 (led by GIUZ) builds an integrative water balance modelling framework for current basin state (WP1, WP2) and future scenario simulations (WP3) that will identify water resources variability and availability. Finally, WP5 (led by GIUZ) will assess the related water risks for different economic sectors and social groups, considering resilience and limits to adaptation. Risk evaluation, and development and evaluation of adaptation strategies will be undertaken using a participatory approach involving local stakeholders. The project addresses several key scientific gaps related to the analysis of current and future water risks in data-scarce mountain regions. The innovation of the approach lies in the combination of climate spatio-temporal interpolation and downscaling methods, participatory scenario development, new applications of integrated hydrological modeling, and stakeholder borne analysis and evaluation of risks and adaptation options. Methodologies and conceptual approaches can be transferred to other regions with similar water risks and sparse data. The project will be conducted in close collaboration between GIUZ, IWS and ZIRIUS, offering a productive research environment. Collaboration with academic and governmental water research and management institutions in Peru with the involvement of local stakeholders ensures salient research results and a strong broader impact.
