Abstract

The contribution addresses urban risk as a systemic condition, and introduces the “Green Nexus Hub” as a design paradigm for the ecosystemic regeneration of residual spaces. Through design practices and methodologies, these sites are reinterpreted as socio-ecological infrastructures capable of reactivating latent ecosystem services, and of fostering inclusive processes. The research integrates a critical review of the literature with the analysis of three case studies – Marseille (France), Bogotá (Colombia), and East Naples (Italy) – selected to highlight recurrent tensions and potentialities. The findings outline an operational framework for urban strategies oriented toward transformative resilience, ecological justice, and design innovation.
