A Methodological Proposal for the Design of Agricultural Parks—The Case of Metropolitan City of Rome

Urbanisation processes have led to the emergence of functional and formal hybrids, blurring and fragmenting the traditional boundaries between urban and rural areas. Agricultural parks have emerged as a planning tool to govern these hybrid areas between ‘countryside’ and the ‘city’, as well as to promote sustainable land use and community development. This paper, analysing the Metropolitan City of Rome (Italy) as a case study, illustrates an innovative pilot methodology for identifying the area of an Agricultural Park and, in particular, the area of the Rome Metropolitan Agricultural Park (MAP), a policy proposal for the metropolitan city. The aim of the article is twofold: to analyse the multifunctionality of farms in the periurban area of Rome to highlight the types of goods and services on which the relationship between farms and the metropolitan population is based and to expose the methodological path on which the MAP policy proposal was developed. A geospatial analysis, using the National Land Consumption Map (LCM) and the CORINE Land Cover (CLC), highlights the main agricultural areas and evaluates their quality. Isochronous curves assess the accessibility, and the GHS population grid (GHS-POP) defines the catchment areas. This approach, building on the 15 min city framework, has analysed the multifunctional farms and the types of goods and services offered to the population. A total of 91,656 hectares were identified as potential geographical areas of the Metropolitan Agricultural Park that could serve nearly 1 million inhabitants between rural and urban areas of Rome. The research highlights its characteristics in terms of the role of multifunctional farms, Alternative Food Networks, and the relationships between consumers and producers.
