In recent years, local food systems have come to be seen as a new possibility in creating markets for family farming. These systems are based on local production and consumption structures, with a primary focus on sustainability, locality and proximity. It is essential to understand the dynamics of these systems and their impact in the context of family farmers. Thus, this article seeks to identify in the literature the main theories and concepts used in the analysis of “local food systems”, verifying the state of the art of its theoretical elements related to the concept of “family farming” in Brazilian and international academia. The methodological procedure employed was a systematic literature review following the Methodi Ordinatio protocol, covering 30 articles indexed in the search portal Periódicos - Capes and in the database ProQuest. The main approaches included in this theme are presented in a summarized form, as well as the research gaps in the area are identified. The results show that these concepts involve themes such as local rural development, politicization of consumption, sustainability, market niches, agroecology, territorial valorization, and institutional programs.
