Équipe : MécaFlu

Abstract: Environmental issues in urban areas are numerous and complex. Among them, handling the volume and quality of storm- and wastewater to avoid disturbances can be achieved with a gradient of approaches. Urban ecological infrastructures host a comprehensive set of ecological functions that can provide ecosystem services to alleviate these disturbances for Human and other species. These social-ecological systems, complex by essence, integrate biophysical and social templates under external constraints. Their associated time dynamics range from minutes to decades, and call for appropriate study time scale. Research questions about interactions between ecological functions, trade-offs between ecosystem services, long- term dynamics affecting both functions and services, and stakeholders evolution impact on their functioning seem relevant to help cities reach sustainable trajectories. In this process of building knowledge and applications, researchers work in a whole ecosystem, significantly structured by young researchers. Getting aware of one’s own vision of supervision, of its numerous values and stances is a first step to guiding them to reach their full potential and bring the most to science - and eventually to Society, and Nature.
