Sistemas tradicionais de manejo de sementes crioulas e o cenário brasileiro de proteção de variedades e certificação de orgânicos: estudo de caso da Rede Agroecológica Metropolitana de Porto Alegre, Rio Grande do Sul

The traditional management systems of landrace seeds have undergone transformations in the current Brazilian scenario of protection of varieties and organic certifications. In this context, the objective of this work is to discuss the vulnerability of these systems when facing the legal frameworks that legitimize and empower the formal seeds system and imposes requirements for the certification process of organic products, from the case study of Organismo Participativo de Avaliação da Conformidade Orgânica, linked to the Associação dos Produtores da Rede Agroecológica Metropolitana (OPAC-RAMA) of Porto Alegre, Rio Grande do Sul. It is noticed that, despite the strong pressure from the legislation of varieties protection on the processes of autonomy of the farmers trying to keep them within a hegemonic system of conventional production, the current legislation of organics is encouraging the resumption of handling landrace seeds. Therefore, farmers' rights to their knowledge and management practices of their landrace seeds are resisting and seeking to become viable, strengthening the agro-ecological processes
