The forum explored how science, territories, and society can jointly design credible and desirable transition pathways and governance models, structured around four key themes:

water & health

water & biodiversity

water & climate

water & sustainable economy

The four thematic focuses of the Grand SWITCH provide a structured journey through contemporary water-related challenges. Designed as spaces for dialogue between science, territories, and society, they highlight the transformations required to address ecological, health, economic, and climate-related issues affecting water resources in the Upper Rhine region. Each session combines scientific insight, territorial anchoring, and contributions from field actors, fostering an exchange between knowledge and practice.

These thematic sessions serve as entry points for understanding the complexity of hydrosystems and the transitions they require. They address the links between water and biodiversity, the health implications of water quality, the interactions between economic uses and resource availability, and the impacts of climate change on ecosystems and territories. Together, they outline the key challenges to be considered in designing sustainable water pathways.

By bringing together scientific expertise, field-based experience, and operational perspectives, these sessions fully embody the spirit of the Grand SWITCH: a space where disciplines converge and territories experiment with new ways of acting. They also highlight the role of Living Labs as living environments for experimentation, collective learning, and innovation in support of sustainability transitions.


Embedded in the ITI SWITCH framework and its Living Labs, the SWITCH Forum showcased cutting-edge scientific knowledge, territorial innovations, and concrete cooperative approaches. This dynamic was further strengthened by the Water Family, the Cross-border Water and Sustainability Chair, and the PEPR OneWater programme, which together foster new governance models, highlight inspiring field experiences, and support operational solutions to enhance water resilience in the Upper Rhine region.

Opening lecture: Follow the water! A catchment perspective on sustainable hydrosystem management
 11/03 | 9:30-10:30

by Karl Matthias Wantzen, Transboundary (EUCOR, UNESCO, RGE) Chair on Water and Sustainability

  • What do we know about the effects of human impacts on the global and regional (catchment) water cycles?
  • From the tragedy of the commons to the tyranny of small decisions: the hard life of an elongate rivers in ellipsoid territories, governed by square-headed decision-makers,
  • Life in the rhythm of the waters: how the natural flow regime shapes both, biological and cultural diversities,
  • Take the bull by its horns: how to increase speed and efficiency in hydrosystem management.

This presentation hinges on a UNESCO study on human-river-relationships worldwide (https://unesdoc.unesco.org/ark:/48223/pf0000382775) and on the development of the new, transdisciplinary Master Course on Continental Water Sustainability

Crossed perspectives

Citizen engagement and scientific research: convergences and tensions
 11/03 | 17h30-18h45

Jean-Yves Georges (CNRS, IPHC)
Cybill STAENZEL (University of Strasbourg, LIVE)
Adrien SAPHY (PhD candidate, forest ecosystem biogeochemistry)

Moderation: Anne Mellier (journalist)

In the context of environmental crises, many researchers engage publicly or alongside civil society. This raises key questions about scientific legitimacy, public positioning, and the balance between advocacy and objectivity.

While some perceive a risk of blurring boundaries between science and activism, others argue that such engagement strengthens the societal relevance of research. This discussion highlights the need for an evolving ethical and institutional framework that recognises engagement as part of scientific practice while ensuring transparency and rigour. It represents a step toward a renewed science–society contract.


Film screening

The Invisible River: a hidden treasure beneath the Rhine plain – Serge Dumont
 11/03 | 19h-20h30

In partnership with the Jardin des Sciences

Introduction by Serge Dumont (Senior Lecturer, University of Strasbourg)

Beneath the Rhine plain flows an invisible river: a groundwater ecosystem where water and life circulate through hidden pathways. In rare locations, it emerges under pressure, forming crystalline streams that host unique biodiversity. This fragile system is threatened by invasive species, intensive agriculture, and water abstraction.

Through his work as both researcher and filmmaker, Serge Dumont documents aquatic ecosystems, particularly gravel pit landscapes in Alsace, in collaboration with the Ried Bleu association.

The film reflects the work of ITI SWITCH, where researchers, stakeholders, and Living Labs study the preservation and sustainable management of aquatic environments and their interactions with human uses.


Water & Sustainable Economy Focus
 12/03 | 9h-10h30

  • Can water be simultaneously a vital resource, a common good, and a driver of economic transition?

  • Balancing water scarcity, social equity, and economic innovation is central to sustainable transformation pathways.

  • Can water become a driver of transition that generates value without becoming a source of conflict or speculation?

Keynote

Hydrostalgia of our liquid bodies
 12/03 | 13h30-14h

By reinterpreting the figure of the Lorelei, a mythical character from the Rhine imagination, this performance explores “hydrostalgia”: an emotional connection to the fragility of hydrosystems.

This reading performance is part of an ongoing art–science research project developed with the CréaLab of the University of Strasbourg.

By LEFEBVRE ZISSWILLER, (artists)
The duo works across documentary and speculative visual practices, exploring human–environment relationships.

 

*The CréaLab is an initiative of the OPUS Hub (Open University of Strasbourg), developed in close collaboration with the Jardin des Sciences and the University’s Cultural Action Service. The OPUS project has received state funding managed by the French National Research Agency (ANR) under the “Investissements d’Avenir” programme (reference ANR-21-IDES-0003).

Whether you are a lecturer, PhD candidate, or professional engaged in sustainability issues, this collaborative workshop is designed for you.

Participants will exchange with peers, explore practical feedback, and contribute to the University’s strategy by helping draft a note aimed at developing interdisciplinarity in sustainability education at the University of Strasbourg (Unistra).


Serious Game : Speaking as a proxy for non-humans in defending the rights of the Rhine 
 12/03 | 16h-18h

The Rhine River has been shaped by human-centered management. This interactive session invites participants to form a “river parliament/assembly", representing non-human species—including the river itself—to envision its future.

Through role-play and discussion, the workshop explores river governance from non-human perspectives and envisions a  restoration plan that centers their rights.

This serious game is organised by Yixin Cao and Thomas Wendt, postdoctoral researchers, bringing together expertise in water governance, environmental justice, and participatory methods.
 

This forum is part of the ITI SWITCH initiative and has strengthened links between research, territories, and socio-economic stakeholders.

The outcomes will directly inform future ITI SWITCH activities and support the development of its research and training programmes.
