indigenous-agroforestry
Indigenous agroforestry refers to traditional land management systems developed by indigenous communities that integrate trees, crops, and sometimes livestock in ways shaped by generations of ecological knowledge. These systems are increasingly studied in plant science for the insights they offer into plant-plant interactions, canopy dynamics, and species selection under real-world conditions. Researchers examine how indigenous agroforestry practices support plant genetic diversity, soil-plant nutrient cycles, and ecosystem resilience in ways that complement or surpass conventional agricultural approaches.

Ancient DNA extracted from Amazonian sediment cores shows that indigenous peoples deliberately cultivated and managed at least 38 tree species across the landscape for more than 4,500 years — meaning the Amazon 'wilderness' is, in large part, a vast inherited garden.
Ancient DNA from 12 sediment core sites identified 38 domesticated tree species concentrated near pre-Columbian settlement sites.
Forest management by indigenous peoples dates back at least 4,500 years, predating European contact by millennia.
Species composition in ancient cores directly matches today's 'dark earth' (terra preta) forests, confirming continuity between ancient cultivation and modern forest structure.
