Abstract

The Ecosystem Services (ES) refer to a decision-making condition in which the existence of many and different aspects (regulatory, provisioning and cultural) imposes a reciprocal trade-off rules that gives some greater legitimacy to others. Dealing with ES in a complex decision-making system encourages evaluations to achieve a short-medium-long-term equilibrium between ES supply and demand in the social, economic, and environmental context of reference.
This is especially exacerbate in the urban settings, where types guidelines of trade-offs alongside those of ecosystem services take action, e.g. in cases to design and program urban land use via Nature-based Solution (NbS).
It intends to present an integrated approach based on multi-criteria logics, with the goal of minimizing the ecosystem service supply and demand trade-off for Nbs allocation across urban areas. The approach's substance lies in the formalization of an optimization algorithm based on ES accounting and the AHP protocol, as well as the financial, economic, environmental, social, and cultural constraints that aid in the case-specific personalization of urban planning and environmental NbS design strategies. An description of the Italian case study, which was examined testing the proposed optimization algorithm, rounds up the presentation.
