YIXIN CAO

Presentation of myself: postdoctoral researcher at the University of Strasbourg, France. She has working experience in both Europe and Asia. Her research examines water as a social-ecological system. Her work focuses on water management and governance, river restoration, river bathing/swimming, non-human and more-than-human justice, and human-nature relationships.

Presentation of my research work:In University of Strasbourg, I study "Social-Ecological Transition of Water Governance: Indigenous Rights of Nature Movement and Emerging River Personhood Initiatives in France". I am involved in the French national research program OneWater – Eau Bien Commun: https://www.onewater.fr/fr, specifically The Target Project (Projet Ciblé) 7 (PC7, Water Governance & Social-Ecological Transition). My project examines emerging movements that recognize rivers/waters as legal persons, reflecting Indigenous-inspired perspectives that see water as a living entity. Through a global review and French case studies (e.g., the 2021 declaration of the rights of the Tavignanu river in Corsica), it analyzes how these legal/social initiatives challenge existing water governance frameworks and explore new pathways for more sustainable and inclusive human-nonhuman relationships.

 

HARRO JONGEN

Presentation of myself: postdoctoral researcher at the Karlsruhe Institute of Technology. At Wageningen University, I followed both my bachelor “International Land and Water Management” and master “Earth & Environment” specializing in hydrology. My PhD was also at Wageningen University and combined hydrology and meteorology to understand the interaction of the water and energy balances in the urban climate. My research interests include hydrometeorology, urban climate, and land–atmosphere interactions, with a particular focus on evaporation processes and the surface energy and water balance. My work combines models such as large-eddy simulations (LES) and urban land surface models with the analysis of observational data to advance understanding of urban climate dynamics and inform climate-resilient urban planning.

Presentation of my research work:

  • WEFLOWS: Water and Energy FLuxes for Optimizing Urban Sustainability
  • This research explores how urban water bodies—such as ponds, canals, and lakes—affect local temperature and humidity in cities. The study aims to understand under which conditions and with what characteristics these water elements help reduce heat stress, when they may have little effect, or even contribute to warming.
  • Highlights
    • The project uses extremely high-resolution (1 m) large-eddy simulations with the PALM model (PALM4U) to capture the heat stress at the pedestrian level.
    • Systematically modeling different design choices will assist in the creation of guidelines for more comfortable open water spaces.
  • Unfortunately, running a model like PALM takes a lot of preparation and I do not have intermediate results to show yet.

Presentation of my research work:

Title of research: Inland Water Conservation across Scales: Harmonizing Governance Instruments

Subject of research: the research addresses the governance of inland water ecosystems, focusing on how policy, regulatory, and governance instruments across international, national, and local levels can be harmonized to improve the protection and conservation of inland waters, including rivers and wetlands.

Innovative elements:

  • Development of an innovative and global governance framework for “riverscape” protection and conservation
  • Introduction of a “gradient” approach to conservation that spans protection to sustainable use, incorporating ecological, hydrogeological, socio-economic, and cultural dimensions (the “riverscape” concept)
  • Inclusion of global mapping analysis to identify spatial overlaps and gaps in river conservation using GIS.
  • Global case study analysis to identify barriers and opportunities in implementing protection and conservation instruments

Intermediate results:

  • Systematic literature review of 156 sources completed, identifying major gaps in current inland water conservation governance
  • Based on literature review, preparation of a journal article titled “Rethinking Inland Water Conservation through a Novel Multi-Scalar Governance Lens: A Systematic Literature Review”.
  • Case study 1 (Mexico) on integrating environmental flow (e-flow) requirements into conservation planning and management: preparation of research concept for the case study and fieldwork planned in August- September (in collaboration with UniversidadNacional Autónoma de México (UNAM) and El Colegio dela Frontera Sur (ECOSUR).

 

 

THOMAS WENDT

Presentation of myself: systems ecologist and PhD candidate focusing on riverine and landscape-scale restoration. My work integrates ecological, socio-political, and strategic planning dimensions to improve long-term restoration success.

Presentation of my research work:
Title:Toward an Eco-Strategic Framework for River Restoration: Lessons from the Upper Rhine
Subject: Analysing past restoration efforts along the Upper Rhine which will result in developing a multidimensional, function-oriented evaluation framework to assess and guide river restoration.
Highlights: The research introduces a decision-support tool scoring restoration success via 8 descriptors (e.g., sediment dynamics, connectivity, stakeholder acceptance), shifting from binary outcomes to a gradient-based, systemic assessment. The tool is informed by research into ecological componentsm stakeholder interviews and database analysis. 
Intermediate Results: Initial application to the Upper Rhine basin reveals critical mismatches between restoration effort and biodiversity needs, as well as systemic barriers to cross-border coordination—informing both ecological and governance improvements.
