They were in Peru and part of the territory of Ecuador, Colombia, Bolivia, Argentina and Chile. The Incas inhabited an untamed land, in the wild, suffered the inclemency of the climate and with a quite rugged and difficult territory, with very steep slopes and soils eroded by rain could practice agriculture. They used some narrow terraces on the coast that did not have water or irrigation channels to tend and dry some agricultural products.
