Food is central to human beings and their social life. The growing industrialization of the food system has led to a greater availability of food, along with an increasing risk perception and awareness in consumers. At the same time, there is an increasing resistance from citizens to the dominant model of production and a growing demand for healthy food. As a consequence, an increasing number of social networks have been formed worldwide involving the collaboration between producers and consumers. One of these networks, the Ecovida Agroecology Network, which operates in Southern Brazil, involves farming families, non-governmental organizations, and consumer organizations, together with other social actors. Using a qualitative approach based on participant observation and an analysis of documents, the article examines this network. The theoretical framework used is social innovation, which is commonly recognized as being fundamental in fostering rural development. Results show that Ecovida has instigated innovations that relate to its horizontal and decentralized structure, its participatory certification of organic food, and its dynamic relationship with the markets based on local exchanges and reciprocal relations. Furthermore, such innovation processes have been proven to impact on public sector policies and on the increasing cooperation between the social actors from rural and urban areas.

In recent years, agroecology has gained prominence as one of the innovative approaches to agriculture that could positively contribute to achieving sustainable food systems. As a transdisciplinary science, agroecology could benefit from the contribution of socio-economic sciences. This study aims to give an overview of how scholars have approached socio-economic issues in the field of agroecology. A scoping review was conducted by using the PRISMA-ScR method, searching both Scopus and Web of Sciences databases. The selected body of literature (183 articles) provides an overview of the key socio-economic dimensions analysed in the literature on agroecology and the results achieved by scholars. The findings allowed drawing the research gaps and the future research directions in this domain.
