This innovative project addresses the issue of users’ participation towards urban development and policies. It is through a transdisciplinary action research that we plan to investigate this issue. Our intention is to develop a community-based methodology taking principles from community psychology and participatory urbanism. This collective research ambitions to be ground-based from the early beginning, identifying non-academic actors and making them co-researchers. Our goal is to generate spatial and social change by empowering communities in regard to urban issues.
