The concluding event of the Ladenburg Research Network “Future Water Conflicts in Germany” was held on November 13, 2025. Participants from academia, practice and interested members of the public came together to discuss the results of this research project, which had been carried out over several years.

The event was opened by Prof. Dr. Julia Arlinghaus, Chair of the Daimler and Benz Foundation, and Prof. Dr. Cordula Kropp from ZIRIUS – University of Stuttgart. At the focus of the non-public program was the presentation of the key findings from this project. Dr. Hannah Kosow, University of Stuttgart, first gave an overview of the simulation game concept. Dr. Wolfgang Hauser, University of Stuttgart, then presented the workshop version of the new Futurescapes Navigator, which had been developed for the simulation games. This open-topic digital web application, which is free of charge following registration, can support the analysis of conflicting objectives and the development of robust strategies. Further information and access to the application and business games are available at https://www.zuwako.de/en/serious-game/.

The three case studies presented and their simulation games provided insights into typical water conflicts in Germany. Simon Brauner, Forschungszentrum Jülich, presented a simulation game relating to conflicting objectives in river basins; Janina Moschner, University of Stuttgart, discussed conflicts arising in agricultural irrigation; and Fabian Hölzlberger, TU Bergakademie Freiberg, shed light on the situation in lignite mining areas. All three case studies showed just how complex and multifaceted water issues can be.

Participants had the opportunity to try out both the web application and the three simulation games for themselves. This practical part met with great interest and gave rise to many discussions. In the subsequent joint feedback session, impressions were collected and an outlook on possible further developments was given.

In the evening, the event was opened to the public. Prof. Dr. Julia Arlinghaus guided attendees through the program in the Max Bense Forum of Stuttgart’s City Library. Two specialist presentations offered different perspectives on current and future water conflicts:
Prof. Dr. Ines Dombrowsky, IDOS / University of Lüneburg, shed light on global interdependencies, while Prof. Dr. Martina Flörke, Ruhr University Bochum, spoke on challenges in Germany.

Prior to the audience discussion, three central theses from the Ladenburg Research Network on future water conflicts in Germany were outlined. The many questions underscored the topical nature of water availability and conflicts surrounding water use. The event provided comprehensive insights into the complexity of future water conflicts in Germany and showed how important it is to develop joint solutions and spaces for dialog and cooperation at an early stage.

Researchers from the Ladenburg Research Network “Future water conflicts in Germany” met now for the sixth time from January 13-14, 2025, on this occasion at the Jülich Research Center. These face-to-face gatherings are an important supplement to the operative meetings, staged online on a weekly basis, in which the members of the research network exchange ideas. The gathering in Jülich marked the beginning of the final spurt for this research group, which will conclude its work in the course of this year.

The doctoral candidates presented their respective qualitative models relating to conflicts of aims in water consumption in catchment areas, regulated irrigation in view of declining water supplies, and the transformation of open-cut mining landscapes. They developed these models together with interest groups using so-called participatory modeling. The models provide the basis for planning games that serve to develop coordinated measures under conditions of uncertainty.

In the course of the gathering, concepts were discussed and refined for the planning game workshops, which are scheduled for early this year together with experts from fields including industry, water management, administration, nature conservation, and agriculture. An approach for further improving and more clearly presenting the “Futurescapes Navigator” internet application developed for the planning games, and joint publication in a scientific journal, were also discussed and agreed. A further key point of discussion was the planning of a final event, at which the project results will be presented to the public.

A hole today, a lake tomorrow? The discontinuation of lignite mining will make it necessary to backfill or flood mines in future. Such flooding projects are controversial, the interests involved are diverse, and their feasibility is uncertain. Where will the water come from – or where will it then be lacking? How will flooding effect the environment? What conflicts of interest exist between the local inhabitants, agriculture, tourism, and industry? The scientists from the Ladenburg Research Network “Future Water Conflicts in Germany” (ZuWaKo) asked themselves these questions during a tour of the Inden open-cast lignite mine that took place as part of a project meeting at the Jülich Research Center from September 26 to 28, 2023.

The ZuWaKo project is currently concerned with problems of water competition and scarcity in Germany that are now emerging or are becoming more acute – also as a result of climate change. The focus here is on the mining sector, but also on river basins in general as well as newly arising conflicts in urban and agricultural irrigation. The goal of the project is to better understand the uncertainty, complexity, and conflicts potentially associated with water issues and to address these conflicts in good time. The project proposes to bring stakeholders and affected parties to the table already today, in order to develop robust strategies that can make a significant contribution toward mitigating conflict. So-called participatory modeling and simulation games are being used for this purpose. In participatory modeling, simplified qualitative models are created that depict future framework developments along with alternative strategies and measures. In the simulation game, these models are used to explore the consequences of one’s own decisions in interaction with those of others. At the gathering, scenarios up to the year 2050, a prototype of the simulation game, and an initial test model were presented and discussed and the next steps determined.
