Evidence of Prehistoric Irrigation in Northern Ecuador

Resumen

AbstractField evidence for the existence of irrigation at a late pre-Inca site in northern Ecuador is examined. The implications of irrigation agriculture are examined with respect to the probable level of socio-political complexity. It is concluded that the pre-Inca societies of northern Ecuador were more stable and more clearly stratified than had been suspected previously. They were, therefore, an attractive addition to the Inca Empire which was unwilling or unable to conquer the jungle tribes only a few kilometers from its capital.
