The Agro-Ecosystems History Laboratory of the University Pablo de Olavide and the think tank Alimentta  are pleased to announce the IX International Congress of Agroecology, which will take place in the capital of Seville, in the facilities of the University Pablo de Olavide, on the dates indicated. The theme of the Congress will focus on the construction of local agroecological based food systems (SALBAs). The most suitable way to achieve the necessary change needed to overcome the food system crisis is the expansion and the consolidation of the numerous alternative food experiences emerged in recent times, aiming to develop the synergies between themselves. Therefore, it is necessary to strengthen the links in the food chain and establish solid alliances between member countries to work together, and to establish alternative food systems to the mainstream sector. In recent years, both social innovation experiences and discussions regarding scaling up these experiences have proliferated, but there are still numerous questions to be resolved regarding the process of implementing SALBAs. This conference seeks to generate a space for exchange and collective debate that will serve to shed light on the progress of the agroecological transition and, more specifically, of the SALBAs.
