This study explores the cultural, productive, territorial, and organizational practices of cacao-producing families in Lebrija, Santander (Colombia), within the broader context of rural sustainability and peasant identity in Latin America. In response to recent national and international frameworks recognizing the rights of peasants, the research aims to document local knowledge systems and community-based strategies that sustain rural livelihoods. Through a qualitative ethnographic approach, including participatory workshops, semi-structured interviews, and social cartography, the study collected narratives, practices, and territorial dynamics over the course of one year. The results reveal that cacao production is not only an economic activity, but a deeply embedded cultural process that intertwines with memory, family ties, lunar cycles, and environmental stewardship. Participants described conflicts related to water access, deforestation, poultry farming, and the expansion of urban infrastructure. Despite these pressures, families demonstrated adaptive capacities through agrodiversity, traditional knowledge, and associative work. The study concludes that these cacao-based practices offer valuable insights into bottom-up strategies for resilience and territorial sustainability and calls for greater inclusion of peasant knowledge in rural development agendas.
