The change from swidden to sawah cultivation in Tara'n Dayak villages
in West Kalimantan, indonesia, is presented as a long-term, complex in
cremental process in which distinct, unstable and often confusing prod
uction technologies figure as transitional forms. The transitional pha
ses are discussed in terms of their efficiency and sustainability. It
is argued that the failure to perceive and understand long-term proces
ses of agricultural change may result in both misinterpretation of tec
hnological patterns and environmental variables, as well as of rules o
f labor and resource sharing.
