Transition from native forest rubbers toHevea Brasiliensis (Euphorbiaceae) among tribal smallholders in Borneo

Abstract

This is a study of the historic transition in Southeast Asia, in particular Borneo, from the exploitation of native forest rubbers to Para rubber (Hevea brasiliensis, Euphorbiaceae). During the second half of the nineteenth century, booming international markets subjected forest rubbers to more intensive and competitive exploitation. At the same time, the settlement patterns of tribal rubber gatherers were becoming more sedentary and their agriculture more intensive. Hevea spp. was better suited to these changed circumstances than the native forest rubbers, largely because it was cultivated not naturally grown. The status of Hevea spp. tn Southeast Asia as a cultigen, as opposed to a natural forest product, and the political-economic implications of this helps to explain the contrasting histories of smallholder rubber producers in the New and OM Worlds. This study offers an historical perspective on current debates regarding relations between forest resources, forest peoples, and the state.
