Nature-Based Solutions for Conservation and Food Sovereignty in Indigenous Communities of Oaxaca

Abstract

The increasing demand for food and the overexploitation of natural resources rapidly deplete the planet’s ecosystems, highlighting the urgent need for sustainable alternatives. Nature-based solutions effectively promote agricultural sustainability and environmental conservation but require continuous financial and political support to overcome existing barriers. This research examines these solutions’ effectiveness in Santa María Jacatepec, a biocultural region of Indigenous peoples in the Papaloapan Basin, Oaxaca, Mexico. A mixed-methods approach combining quantitative and qualitative analyses uses National Institute of Statistics and Geography data to evaluate socioeconomic and environmental indicators. The results indicate that despite pressures to develop cattle ranching, communities have maintained rain-fed agriculture, especially the milpa system, ensuring food sovereignty and preserving agricultural biodiversity. Additionally, implementation of Voluntarily Conserved Areas has facilitated access to payments for environmental services, incentivizing ecosystem protection. However, financial and structural challenges persist, limiting the expansion of these solutions. Santa María Jacatepec exemplifies how Indigenous communities can apply nature-based solutions to strengthen agricultural sustainability and environmental conservation. Integrating traditional knowledge and strengthening conservation policies can enhance community resilience and ensure sustainable development amid increasing pressure on natural ecosystems.
