Colca Canyon: agricultural terraces

Pre-Inca terracing in Colca Canyon is ubiquitous--there are thousands of terraces in this area. The Collaguas who belonged to the group of Aymara cultures were masters of constructing agricultural terraces. Terraces created level land that made cultivation easier. Terracing also helped control erosion and were part of the their complex irrigation systems that included aqueducts. As some of these terraces are up to a thousand years old, this kind of agriculture clearly is sustainable. When the Incas started to control the Colca Canyon around 1320 they adapted the Aymara technique of terrace building and applied it elsewhere in the Inca Empire.
