Résumé
La bonne gestion de l'eau dans nos agglomérations joue un rôle crucial dans l'atténuation des menaces posées par le changement climatique (chaleur, sécheresse, fortes précipitations). L'eau doit être intégrée dans la conception des espaces urbains et de leurs infrastructures. Elle doit être retenue, évaporée, utilisée et évacuée en toute sécurité en cas de fortes précipitations. Cela offre de nombreux avantages aux personnes et à l’environnement.Certaines communes en Suisse, notamment les grandes, jouent le rôle de pionnier et montrent l'exemple. Pour que le savoir-faire atteigne aussi les communes plus petites et tous les acteurs impliqués, l'Association suisse des professionnels de la protection des eaux (VSA) a lancé début 2022 avec différents partenaires pluridisciplinaires un projet au niveau national avec le but de créer une plateforme qui rassemble le savoir-faire disponible, le traiter sous forme d'exemples de «°bonnes pratiques°» et fournir aux communes et planificateurs des instructions concrètes sur une manière de procéder structurée et globale. Le projet se concentre également sur les outils et les processus nécessaires à la promotion de la collaboration interdisciplinaire (hydrologie, sol, urbanisme, biodiversité et d’autres).
Good water management in our cities plays a crucial role in mitigating the threats posed by climate change (heat, drought, heavy rainfall). Water must be integrated into the design of urban spaces and their infrastructure. It must be retained, evaporated, used and safely disposed of during heavy rainfall. This offers many benefits to people and the environment.Some municipalities, especially the larger ones, are taking the lead and setting an example. In order to ensure that the know-how also reaches smaller communities and all the actors involved, the Swiss Water Association (VSA), together with various multidisciplinary partners, has launched a nationwide project with the aim of creating a platform that collects the available know-how, processes it in the form of examples of "good practice" and provides communities and planners with concrete instructions on how to proceed in a structured and comprehensive manner. The project also focuses on the tools and processes needed to promote interdisciplinary collaboration (soils, hydrology, urbanism, biodiversity and others).
