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.

This article seeks to analyze the public procurement program for school feeding in Distrito Federal, Brazil from the perspective of short food supply chains (SFSCs) and quality construction. Semi-structured interviews were applied to key actors involved in the Program. The results of this research show that, mainly through the regulations around Food and Nutritional Security and in the encouragement of local family farmer markets, the State has acted for a quality shift through public purchases and, mainly by means of norms such as laws, decrees, and normative instructions, induced a quality change in the production and consumption processes. This study contributed to an understanding of how Executing Entities such as states are working to acquire local and quality agricultural products, which benefits local farmers and improves the quality of school meals.

El objetivo de este artículo es analizar a través de una revisión en profundidad de la literatura, los principales aspectos de las cadenas agroalimentarias sostenibles, relacionándolos con los conceptos desarrollados por la investigación sobre “sistemas agroalimentarios locales”, percibiendo así la necesidad para lograr la sostenibilidad en las dimensiones (económica, ambiental y social), la dificultad de adaptarse a los estándares y normas de calidad en los sectores público y privado, de ser más transparentes y brindar alimentos asequibles con alta calidad y diversidad. Es un trabajo cualitativo de revisión bibliográfica. El procedimiento adoptado es una revisión exploratoria de la literatura en la academia nacional brasileña e internacional Como resultado, se identifica la noción de millas de Alimentos, cadenas cortas de suministro de alimentos y cuenca alimentaria como elementos con potencial para generar innovación y transformación hacia cadenas agroalimentarias sostenibles en los sistemas locales. Este estudio contribuye al debate sobre la sustentabilidad en el sector agroalimentario y a la discusión que involucra a los agricultores familiares en economías de escala local, y puede ser utilizado como subsidio para políticas públicas para esta clase, así como para promover el debate sobre alimentación y seguridad nutricional.
