Under the Inca
The Inca state drew its taxes through both tax in species and corvée labor drawn from lineages and administered through a bureaucracy composed largely of local nobility. The corvée labor force was used for military operations as well as public working projects, such as roads, aqueducts, and storage buildings requested as tampu and qollqa. There were parallel institutions of lineage-based colonies call as mitmaqkuna, which proposed goods for the state and submission strategic security in newly acquired areas, and yanakuna, which were retainers with labor obligations to higher members of the state. Lands belonging to the Sapa Inca, the state church, and to panaqas lineages descending from individual Sapa Incas according to the principle of split inheritance were often vertical arrayed to access a sort of resources. Indeed, it has been widely suggested that the terraces at Moray were testing grounds for instituting which crops would grow under what conditions in formation to more efficiently exploit ecozones. The terraces were apparently constructed so that different temperatures and humidities could be achieved through the creation of microclimates, and therefore cause different kinds of crops.
