The study done in the Maring community of Papua New Guinea by Roy A. Rappaport during 1962 and 1963 is a good illustration of the bush fallow system of subsistence farming.

Rappaport conducted research on the Maring in the 1960s, publishing his work in a book entitled Pigs for the Ancestors.

The Maring are known for a special pattern of farming, hoarding of pigs, and warfare. Warfare usually proceeds after a ritual pig feast, known as kaiko.
