<Ul> <Li> </Li> <Li> </Li> <Li> </Li> </Ul> <P> Incan 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 . Inca agriculture was also characterized by the variety of crops grown, the lack of a market system and money, and the unique mechanisms by which the Incas organized their society . Andean civilization was "pristine"--one of five civilizations worldwide which were indigenous and not derivative from other civilizations .

The Incas had to overcome the adversities of the Andean terrain and weather . Their adaptation of agricultural technologies that had been developed by previous cultures allowed the Incas to organize production of a diverse range of crops from the arid coast, the high, cold mountains, and the humid jungle regions, which they were then able to redistribute to villages that did not have access to the other regions . These technological achievements in agriculture would not have been possible without the workforce that was at the disposal of the Inca emperor, called the Sapa Inca, as well as the road system and extensive storage systems (qullqas) that allowed them to harvest and store food and to distribute it throughout their place of civilization . </P> <P> The heartland of the Inca Empire was in the high plateaus and mountains of the Andes of Peru and Bolivia . This area is mostly above 3,000 metres (9,800 ft) in elevation and is characterized by low or seasonal precipitation, low temperatures, and thin soils . Freezing temperatures may occur in every month of the year at these altitudes . </P>
