This article analyses the influence of the socio-technical networks associated with agroforestry systems (AFS) on the diversity of cacao agroforestry systems (CAFS) in the Eastern Brazilian Amazon, in the municipalities of Irituia and Tomé-Açu. Fieldwork was carried out through semi-structured interviews, participatory activities and agrarian diagnostics. Three types of CAFS were identified: Group 1 was “market-oriented”; Group 2 was related to “food sovereignty”; and Group 3 was “syntropic”. The socio-technical networks appeared fragmented: an institutional network in Tomé-Açu focused on cacao intensification, while an agroecological network, predominantly in Irituia, pertained to cooperatives and local associations. Group 1, as part of the institutional network, uses intensive techniques. The second and third groups adopt alternative strategies: Group 2 uses crop diversification and certified markets, while Group 3 focuses on syntropic agriculture to regenerate degraded land. Connecting these networks could facilitate knowledge and practice exchanges, contributing to more resilient and sustainable production systems.
