Prehistoric agricultural production on Easter Island (Rapa Nui), Chile

Abstract

A survey of the Easter Island landscape has resulted in the recognition of numerous lithic mulched household gardens and fields. It is proposed that lithic mulching was a technological innovation introduced to enhance the moisture retention capacity of the excessively drained island soils, and was an innovation incorporated into élite managed field systems which arose in the early 15th century to meet the demands for surplus production.
