Inca agriculture was the culmination of thousands of years of farming and herding in the high-elevation Andes mountains of South America, the coastal deserts, and the rainforests of the Amazon basin. These three radically different environments were all part of the Inca Empire (1438-1533 CE) and required different technologies for agriculture .
