Integrated Multi-Level Assessment of Ecosystem Services (ES): The Case of the Casal del Marmo Agricultural Park Area in Rome (Italy)

Abstract

The aim of this study was to investigate the role of the ES assessment within a “place-based policy-mix model” for urban planning testing and integrating three ES assessment methodologies: (1) mapping and assessment, (2) expert-based evaluation and (3) social perception. The results indicate that (1) mapping assessment provides higher values to the regulating ecosystem services, (2) expert-based evaluation provides slightly lower values to the regulating ecosystem services and (3) social perception highlights the importance of cultural ES but tends to underestimate other ecosystem functions. These three methodologies translate into sectorial and nondialoguing policies for which decisions are made on partial and nonintegrated information. In order to design integrated policies with a view to the sustainability of the local food system, our results indicate that the planning of urban and peri-urban agricultural areas should rely on tools capable of integrating both spatial mapping methods and human-based assessment methodologies.
