Traditionally, Dayak agriculture was based on actual integrated indigenous farming system. Iban Dayaks tend to plant paddy on hill slopes while Maloh Dayaks prefer flatlands as discussed by King. Agricultural Land in this sense was used and defined primarily in terms of hill rice farming, ladang (garden), and hutan (forest). According to Prof Derek Freeman in his Report on Iban Agriculture, Iban Dayaks used to practice twenty-seven stages of hill rice farming once a year and their shifting cultivation practices allow the forest to regenerate itself rather than to damage the forest, thereby to ensure the continuity and sustainability of forest use and/or survival of the Iban community itself. The Iban Dayaks love virgin forests for their dependency on forests but that is for migration, territorial expansion, and/or fleeing enemies.
