The Management of Late Andean Irrigation Systems on the North Coast of Peru

Abstract

Documentary research combined with field study has made possible the reconstruction of the sociopolitical organization of the Late Prehispanic Chimu and Chimu-Inca polities of the North Coast of Peru. Many aspects of the management of the large-scale irrigation networks of the region are integrated into that organization. Rights to the water of a particular canal–and to the lands it watered–can be shown to have been vested in socio-political groups which occupied different hierarchical positions according the size of the canal. Maintenance, repair, and distribution of the water were carried out by these groups; there was no centralized state bureacracy to oversee hydraulic affairs. Understanding the organization of the canal system permits a series of hypotheses for the reconstruction of ancient territorial units and the organization of settlement patterns within them.
