Livestock farming systems have an important role in the territorial systems of the Mediterranean, but in the last twenty years the sector has undergone serious changes with an important decrease in the number of farms. The purpose of this study is to show the contribution of a local food certification to the resilience of peri-urban livestock farming system and of its food supply chain at territorial level. The focus is on the "Carne Bovina di Pisa" project, a private label promoted by the local livestock producers' association, with the purpose of preserving biodiversity and provide farmers with an opportunity to strengthen their local marketing power. The case study is the peri-urban area of Pisa (Tuscany, Italy), representative of the urbanized Mediterranean coastal plains with high urban pressure on agricultural land and increasing agricultural abandonment in the peri-urban area. The analysis is based on the qualitative analysis of interviews to stakeholders and the quantitative figures about the changes in livestock system. Results show that the label has positively sustained both the resilience of farming systems and the local food supply chains.
