Hydronexialism

Hydronexialism (Wantzen, 2025) is a holistic approach to face the policrisis of sociohydrosystems by combining knowledges and techniques from all adequate scientific and social fields. Scientific disciplines such as hydrology, sociology, ecology etc. are considered as a toolbox providing options for problem-solving. Critically checked (peer reviewed or probabilistic) information from research and practical experienced is combined by teams of nexialists who collaborate to find the most efficient and adaptive solution to a given problem. For example, a dam removal project to restore passability for migratory fish and other ecosystem services, may fail its targets (despite being technically excellent), if it was not supported by the people that are directly concerned by the project (example: interuption of the French dam removal program after protests following the Selune dam removals). Hydronexialists delve into the valuescapes of all concerned stakeholders (human and non-human) and are able to co-develop solutions, communicating them within the team and among the team and the participating parties.
