    SyKonaS - Projektbericht. Nr. 5, Systemische Analyse der Wechselwirkungen zwischen Konfliktlinien und Rahmenbedingungen der Energiewende: Weiterentwicklung soziotechnischer Energieszenarien
    (Stuttgart : Verbundvorhaben SyKonaS, Zentrum für interdisziplinäre Risiko- und Innovationsforschung der Universität Stuttgart (ZIRIUS), 2024) Hauser, Wolfgang; Wassermann, Sandra; Oviedo, Patricia; León, Christian D.; Weimer-Jehle, Wolfgang; Jaschek, Carolin (Mitwirkende); Prehofer, Sigrid (Mitwirkende)
    Im Teilvorhaben SyKonaS/iKonS („Systemische Konfliktanalyse mittels Szenariotechnik“) wurden die technoökonomischen Szenarien um soziale Größen ergänzt und zu soziotechnischen Szenarien weiterentwickelt, um ihre jeweilige Konflikthaftigkeit abzuschätzen. Hierfür wurden zwölf durch die technoökonomischen Energieszenarien vorgegebene Größen (wie z.B. die installierte Leistung von Wind onshore im Jahr 2050) und ihre Wirkungen auf zwölf sozio-politische Größen abgeschätzt. Ebenso wurden die Interdependenzen der soziopolitischen Größen erhoben. Es wurde dann die Frage gestellt, welche Konflikte von den verschiedenen Energieszenarien und ihren gesellschaftlichen Wirkungen ausgelöst werden können.

    Uncharted water conflicts ahead : mapping the scenario space for Germany in the year 2050

    Introduction: In recent years, conflicts surrounding the use, distribution, and governance of surface water and groundwater in Germany have gained prominence in the media, on the political agenda, and in research. Increasing effects of climate change, such as heatwaves and drought but also extreme rain events and flooding, are considered to become more prominent and pressing in the future by different societal actors. However, it remains highly uncertain if and what type of conflicts related to water quantity Germany might actually face in the future (and how they will be framed). This paper addresses one dimension of this uncertainty - namely the future context uncertainty of possible resource and water governance conflicts. Our research contributes to an improved understanding of the uncertainty concerning future climatic, natural, land use related, political, economic, and other societal contexts that could impact water conflicts. Method: We ask: What are possible coherent context scenarios for Germany in the year 2050, and how are they expected to influence future water conflicts? In an expert-based process, we apply a qualitative and systematic method of systems analysis, cross-impact balances (CIB). With CIB, we build internally consistent scenarios of possible futures and map the future scenario space. Results and discussion: Diversity mapping with a new CIB web application of the ScenarioWizard reveals that the scenario space is rather large and diverse. The identified scenario space of n = 355 internally consistent scenarios spans four most diverse scenarios “Polycrisis,” “Economy and agriculture in crisis,” “Growth through adaptation to climate change,” and “Sustainable transformation.” Depending on the development of future contexts, the risk for future water resource and governance conflicts may unfold in various ways. We conclude that our scenario analysis provides a useful base for research and practice to address the context uncertainty of water conflicts in Germany. Our results can be used for risk assessment, to define societal framework assumptions for societal-hydrological modeling, and to develop robust and adaptive strategies and policies.
