Examining the expected benefits of small-scale NbS implementation in Chania city center

The potential of Nature-based solutions to address multiple urban challenges and support urban resilience is widely recognised and documented. Towards enhancing the effects of existing urban green, and harnesing the most of the NbS services, it is necessary to identify all available urban spaces that can accommodate small-scale NbS implementations. In this study, a green wall and a green roof are planned for installation in a concrete-dominated area at the city centre of a small Mediterranean city (Chania, Greece). The potential benefits of the interventions on urban microclimate regulation, carbon sequestration, air pollution mitigation and aesthetic value of the area are investigated combining simulations and literature data. We discuss the synergistic effects of the obtained results and highlight that many microinterventions are needed to harness their cumulative effect on city scale.
