Des représentations concurrentes de l'eau dans les projets urbains. Le cas des prairies Saint-Martin à Rennes

Abstract : ABSTRACT-While the objective is to make water and aquatic environments a central component of the urban project, wetland redevelopment operations reveal competing environmental causes. Public policies tend to use of ecosystem models to promote exclusive environmental concerns, limiting human presence to "naturalis-tic" observation. This ecological position competes directly with logic of water valo-rization in the public space, dominated by a landscape approach and a representation of an "urban nature" hygienized and controlled with regard to flood risk. These three motives oust a fourth, historical and social cause, that of "plural water" and the perpetuation of uses prior to the project (vegetable gardens). Based on a case study of a project to develop a floodplain area along the Vilaine River in the center of the Rennes conurbation, this analysis shows that the reduction of tensions has been resolved in the project by compart-mentalizing water spaces and uses, with different zoning that help to perpetuate the hydro-social cycle of "modern water" and prevent any other form of use of the area.
