Ahupuaʻa is a Hawaiian term for a large traditional socioeconomic, geologic, and climatic subdivision of land. It usually extends from the mountains to the sea and generally includes one or more complete watersheds and marine resources. The predominant traditional system in the eight high islands of the main Hawaiian Islands was based on the ahupua’a. Each ahupua‘a contained a cross section of island resources and they were managed within a complex social system associated with each area. The general belief is that each ahupua‘a met the needs of the local population, with excess for tribute and trade.
