Adapting water management to current environmental and societal changes and meeting the challenges of the future requires considering local issues in order to imagine future developments. From this point of view, the geoprospective scenario approach based not on a top-down approach, but on the perceptions and visions of the various stakeholders of the territory, users of this resource, in an original bottom-up approach, is a way to create the conditions for a concerted and sustainable management. The RADHY-Buëch research project (2019-2022) conducted in collaboration with INRAE (National Research Institute for Agriculture, Food and the Environment) and the Joint Research Unit 7300 ESPACE in Nice has tested the feasibility of this. Located in the middle of the Mediterranean mountains in the south of France, the Buëch basin is under pressure from water resources that can be significant at certain times of the year, and require adaptation by all its users. One of the aspects of the research carried out aimed at proposing scenarios of local adaptations to the risk of drought, based on a co-constructed vision between researchers and actors of the territory. It thus extends the reflections carried out in the Water Resource Management Plan (PGRE) of the Buëch watershed published in December 2019, by adopting a prospective and territorialized vision._x000D_
The present communication traces the methodological approach adopted in this context, from the acquisition of visions of the future of water in this basin thanks to a survey offering the particularity of integrating a spatio-temporal dimension of the resource and water uses, to the construction of three geoprospective scenarios for this territory._x000D_
