Dans les années 2010, des politiques urbaines de résilience et de soutien de la biodiversité sont mises en avant, avec pour coeur une gestion renouvelée de l'eau en ville. Pourtant, les travaux de recherche font plutôt état d'une faible efficacité des politiques urbaines environnementales, et interrogent la désirabilité d'une réforme du rapport entre environnement et ville. Les travaux identifient cependant une transformation forte de la gestion urbaine de l'eau depuis les années 1970.Nous proposons de prendre au sérieux la possibilité d'une inflexion écologique et climatique de la gestion des eaux de pluie et des cours d'eau urbains, au moyen de trois hypothèses : celle de la constitution d'une doctrine technique fondée sur des principes écologiques et climatiques ; celle de la transformation de l'hydrologie urbaine, par la démultiplication de nouvelles techniques ; et celle de l'extension de cette doctrine technique à l'urbanisme.Ces hypothèses sont testées par l'étude de la doctrine au prisme des thèmes de l'écologie et du climat, par celle d'un inventaire des techniques issues des doctrines de gestion de l'eau et du témoignage des gestionnaires, dans l'agglomération parisienne. Cinq sites sont étudiés.L'écologie est présente dans la doctrine et les pratiques en tant qu'auxiliaire de l'assainissement, et une éthique écologique est incorporée aux doctrines techniques. L'hydrologie de l'agglomération parisienne n'est pas massivement transformée, cependant elle évolue dans ses marges. Enfin, les quartiers urbains ne sont pas transfigurés par la gestion de l'eau, celle-ci reste ténue, discontinue, sous-jacente et précédée par d'autres logiques d'organisation et de structuration spatiales. ; Since the 2010s, strategic local policies concerning urban resilience and biodiversity support are being promoted, focusing on ways to renew urban water management. Research points however, to the low effectiveness or efficiency of such urban environmental policies, and questions the need of renewing the relationship between the environment and the city. Other researches put forward that a major change occurs in urban rainwater management since the 1970s.We follow the idea of an ecological and climatic transformation of rainwater and urban rivers management since the 1970s. Three hypotheses underlie this thesis. First, based on ecological and climatic principles, a technical management doctrine transforms the urban water engineering. Secondly, urban hydrology has experienced a shift, carried out by new techniques. Thirdly, this technical doctrine has extended to urban planning and design.We tested the hypotheses by the study of a corpus of guides and technical documents produced between 1970 and 2015; of an inventory of techniques; and of five case-studies, completed with interviews with professionals.The study found that ecology is present, but as an auxiliary to sanitation principles. An ecological ethic is incorporated into technical doctrines: the use of living organisms in engineering is partially based their supposed superior effectiveness in spatial planning. The hydrology of the Paris metropolitan area seems to be marginally evolving. Urban neighborhoods are not transformed by water management: urban water spaces and facilities remain tenuous, discontinuous, underlying and preceded by other logics of spatial organization.

International audience ; We argue here that public space research might benefit theoretically from the Southern Turn in urban studies. Our first objective is theoretical and methodological: unpack the idea of public space to make it suitable beyond its original location. Détienne's work on Comparing the Incomparable, combined with Staeheli and Mitchell's notion of "regimes of publicity" offer the theoretical tools for such a displacement. We end up thinking about public space as various, context-specific configurations of loosely structured, juridical, political, and social elements that take on new shapes and are prone to partial dislocation when dis-located. We test this model by displacing it to a piece of vacant land ― Rondebosch Common in Cape Town. In so doing, we deal with our second objective: offering a detailed empirical analysis of the Occupy Rondebosch Common 2012 events, which relates to broader public space debates in contemporary, liminal, South Africa.
