This articles narrates a transect of designs unfolding in the public space in Brussels and Wallonia, for which different social-ecological dimensions are illustrated. Our intention is to highlight to what extent the dynamics underpinning these social-ecological dimensions are co-produced and can, in some cases, generate each other. Our working hypothesis is that by adopting an “urban ecology†lens as described above, different dimensions can be tied together in a non-binary (social/environmental) narrative. On the one hand, environmental dimensions of some designs focusing on flood mitigation and rainwater harvesting, role of native species and biodiversity, and slow circulations are envisioned through their potential to improve social cohesion at the neighborhood or site level, resulting in an integrated socio-environmental composition. On the other hand, some projects highlight the importance of other kinds of diversities (beside ecological diversity) and are built around the design of multi-use social activities involving a wide spectrum of users. Finally, economic dimensions are more explicitly integrated in some designs, showing how an intervention in the public space can reinvigorate the local economy of residents. This goes beyond reiterating the well-known importance of designing with local stakeholders and shows how their situated knowledge can be embedded in several stages of the design process. It is important to highlight that not all the projects are located in densely inhabited urban areas, such as Brussels or Charleroi. Some are located in more peri-urban or rural areas including Seneffe, Braives, Oupeye, and Esneux. Challenging rigid conceptualization of the urban-rural boundaries and fostering deeper understanding of dynamic ecosystem transitions are among the key ambitions of our urban ecology approach.
