Agroforestry as a Driver for the Provisioning of Peri-Urban Socio-Ecological Functions: A Trans-Disciplinary Approach

Peri-urban rural system rehabilitation is pivotal to the socio-ecological balanced functioning of urban systems. In this paper, we investigate the performance of agroforestry participative practices in rehabilitating peri-urban belts (in-field productive agroforestry; between-field landscape features). We test a new trans-disciplinary, multi-level analytical framework for the ecosystem services (ESs) assessment based on site-specific socio-ecological information. We parallelly analyse ecological and cultural traits: 1. agroecosystem components (flora-vegetation; human community); 2. their organization at the landscape level (landscape eco-mosaic; cultural landscape); and 3. their socio-ecological functions/processes. We compare the current state with a transformation scenario. The first application to the "Milano Porta Verde" agroecology hub, Italy, outlined: 1. the agro-eco-mosaic structuring and diversification improvement consequent to the agroforestry model spread (higher natural components percentage, agricultural patch shape complexity, landscape heterogeneity, landscape structural diversity, connectivity and circuitry); and 2. the cultural functions provided by participative practices (40 initiatives; 1860 people involved; 10 stakeholder types), enabling cultural landscape rehabilitation processes (higher accessibility, citizen empowerment, community and knowledge building, cultural values building). These results qualitatively inform the ES analysis. The potential ES supply matrices and maps showed an increase, through a transformation scenario, in the total ESs delivered by natural components (+44% support ESs; +36% regulating ESs) and agricultural components (+21% cultural ESs; +15% regulating ESs).
