There is a rising demand to use nature and natural processes to address a different range of urban issues, especially when looking at the risk of pluvial flood associated with climate changes and urbanization processes. Among the set of Nature-Based Solutions used in urban planning, Sustainable Urban Drainage Systems (SUDS) represent promising solutions to reduce the negative effects of urban water run-offs and to increase urban Ecosystem Services. However, SUDS can impact differently in the urban fabric and generate positive effects only on particular portions of cities. Planning of SUDS should try to consider not only the number of potential beneficiaries but also where beneficiaries are located in the city, as water sensitive approaches to urban planning must deal with distributive, procedural and contextual dimensions of equity. In this paper, we simulate different spatially explicit planning scenarios of SUDS for densely populated catchments in Sicily. Particularly, we evaluate the relation between the quantitative performance of SUDS in terms of reduction of hazard/risk of pluvial flooding and the number and location of beneficiaries -intended here as residents of different social groups. Results suggest that scenarios of SUDS generate benefits that are not equally distributed within the city.
