Use and ownership of land and resources in two related societies of lowland
Papua New Guinea are shown to covary with residence, gender marriage, Kins
hip, and local understandings of rights that are accorded by either convent
ions of practice or conventions of inheritance. We argue that the articulat
ion of these material and social relations is predicated on the potential f
or a lack of congruence between discourse and behavior. Differences between
the societies, and changes observed in one of them, inform a model of the
transformation of use-rights in nonhierarchical and communally based system
s. Under that model, an ideal of free access gives way to an ideal of restr
aint, an expectation that permission will be sought gives way to a requirem
ent that an invitation be offered and an understanding that women are excha
nged in marriage gives way to an understanding that it is both women and th
eir rights to use land and resources that are exchanged.
