Intensification and Social Complexity in the Interior Lowlands of Papua New Guinea: A Comparison of Bedamuni and Kubo

Kubo and Bedamuni are linguistically, culturally, and technologically related societies of the interior lowlands of Papua New Guinea. They occupy similar environments and have access to essentially the same resources. They differ in population density (Kubo 0.4 people/km², Bedamuni 7/km²), subsistence orientation (Kubo are hunter-gatherer-like, Bedamuni are farmers who hunt) and intensification of plant food production (Kubo lower, Bedamuni higher). Relative to Kubo, Bedamuni are shown to exhibit increased differentiation within and between production units, greater integration within and between residential units, and heightened forms of evaluation within and between cultural systems. Each of these general characteristics is illustrated by particulars that refer, for example, to role differentiation, rights of access to land and resources, dispute resolution, mechanisms of inter-community cohesion, and exegesis with respect to subsistence practices and cultural identity. In turn, differences between the two societies in terms of these general characteristics sustain an interpretation that Bedamuni is a socially more complex society than Kubo. The awkward notion of complexity is examined; it is understood to comprise two independent dimensions—the “involvement of parts” (which is itself multidimensional) and the “individuation of form.” The latter dimension has received too little attention in discussion and definitions of complexity.
