To achieve the systemic change embedded in the sustainability transition, power structures and perspective must be changed. That’s why this project directs its attention to the diverse needs, hopes, and potential of the citizens. The purpose is to strengthen their agency in creating sustainable urban areas. In the shadows of the currently dominant urban planning narratives, alternative citizen-driven approaches and action for environmentally sound and socially just urban spaces can be found. This project explores these alternatives. Further, this project strengthens the science-citizen interface in the hopes of empowering both citizens and researchers.
