Cocoa agroforests in the Brazilian Amazonia floodplains: a review
摘要
Cocoa agroforestry systems in the Amazonian basin floodplains are a sustainable and productive way to ensure food security while preserving biodiversity. This narrative review explores the agronomic, economic, and socio-ecological aspects of cocoa cultivation, analyzing its origin, diversity, and distribution from a historical perspective. The region’s producer families, including ribeirinho, indigenous, and quilombola communities, have historically managed “wild” cacao through sustainable extractive practices, maintaining high genetic diversity. Cocoa genotype dispersal is closely linked to indigenous migration patterns and the role of river basins in genetic exchange. Ecologically, these floodplain agroforestry systems integrate cacao with other perennial and annual crops, creating high-agrobiodiversity landscapes known as traditional “caboclo” agroforestry systems. Beyond these traditional systems, new agroforestry models have been developed in degraded floodplains, promoting sustainable intensification as an environmentally friendly and climate-smart alternative. Proper management can enhance productivity beyond national averages, making these systems economically viable while maintaining ecological balance and ecosystem services. Despite their resilience and potential, cocoa-based agroforests face challenges, including limited technical assistance, market constraints, land tenure insecurity, and insufficient institutional support. Strengthening cooperatives, improving access to credit, and modernizing marketing strategies can enhance economic returns and ensure long-term sustainability. Since cocoa cultivation in the floodplains relies on no external inputs, public policies that add value to riverine products and expand market opportunities are essential. In addition to economic benefits, these systems contribute to the cultural-ecological heritage of Amazonian cocoa cultivation, reinforcing the deep connection between local communities, biodiversity, and sustainable land use, ensuring their continued role in regional livelihoods.
