This research aimed to investigate the practice of family farming in the municipality of Passagem, located in the Agreste region of the State of Rio Grande do Norte. The research problem was outlined based on the need to understand the sustainability of agroecosystems in this territory, considering its strengths and weaknesses. Initially, a diagnosis of the territory was carried out based on 30 indicators distributed in 5 dimensions of sustainability: environmental, technical-productive, economic-productive, socio-cultural and political-institutional. The data from this diagnosis were analyzed using the (S3)-Biogram methodology, which allowed the exposure and assessment of the sustainability of the agroecosystems studied for the 2022 agricultural year. Based on this assessment, an agroecological transition plan is being prepared for the territory under study, considering its strengths and weaknesses identified in the sustainability assessment. This research is qualitative and quantitative in nature, with a descriptive character, complemented by bibliographic research, field observations, interviews and photographic records. The sample consisted of 97 family units of agricultural production, covering all rural communities in Passagem-RN: Lagoa Redonda, Oliveira, Lagoa da Esperança, Iraq, Jacu dos Adelinos, Jacuzinho, Baixio, São Bento, Cipoal, Passagem de Baixo, Jenipapo, Canga and Seixo. Preliminary results confirm that the most vulnerable indicators are: A4 - Issues associated with land use and occupation; A5 - Environmental impacts caused to wild fauna; T5 - Practices to combat phytosanitary occurrences; E1 – Average monthly family income; E2 - Production flow; S4 - Rural violence and P4- Land regularization. In addition to the thesis, the technical product of this research is a Conclusive Technical Report, which is in the writing and layout phase, containing the results of the sustainability assessment, the proposed agroecological transition plan for agroecosystems, as well as guidelines that may support the municipal management teams and local rural extension, providing guidelines for necessary interventions in that territory.
