Social impacts of Purépecha barter: Insights for sustainable communities in the global era

This research analyzes the social impacts of the Purépecha barter market (“tianguis de trueque”) in the Lake Patzcuaro region, Mexico, as an alternative economic practice that fosters socioecological resilience and community sustainability. Employing a mixed-methods approach which included surveys conducted in 2024 and ethnographic observations and interviews from 2020 to 2025, the study reveals the persistence and value of the barter market for the exchange of regional foods, characterized by high female participation. The findings highlight its role in local food security, women's empowerment, and connection with natural resources, demonstrating its potential for sustainable communities and the SDGs. Challenges to its coexistence with other forms of commerce and the need for regulation are identified. This study proposes future actions involving intersectoral dialogue, institutional support, network strengthening, research, and awareness-raising to ensure the viability and maximize the positive social impact of this traditional practice. Notably, this research received funding and support from the State Government through its Science and Technology Institution, underscoring the official recognition of the importance of understanding the social and cultural impact of ancestral practices for sustainable development.
