The concepts of Food Security and Sovereignty are marked by different meanings and strategies for their implementation, including controversial components. In Latin America, there are numerous challenges to achieving Food and Nutrition Security (FNS) and so, achieving Food Sovereignty. Considering the relevance of the creation of regulatory frameworks in such countries, and the significance of regional articulation to overcome these challenges, the aim of this article is to both, identify and describe the legal and conceptual frameworks on Sovereignty and FNS, in Latin America. This study has been developed through a qualitative approach. Google has been used as a search tool for the national regulatory frameworks, by combining different keywords. It has been noted that, in the region, the existence of legislation on FNS is a key factor, where 32 out of the 33 autonomous Latin American countries have set national regulatory frameworks, or action plans to deal with FNS. As for the concepts of FNS, Food Sovereignty, and Food Systems, they appear prominently in the legislation of the region, including Food Insecurity (FI). Finally, the identification of multiple perspectives on the subject in the region should be acknowledged as a strength that shelters the diversity of expressions of resistance and cultural resilience of traditional food systems, and not as a barrier to the construction of cooperation initiatives.
