Local Knowledge and Management of Sago Palm (Metroxylon Sagu Rottboell) Diversity in South Central Seram, Maluku, Eastern Indonesia

Abstract

Given the cultural importance of palms it might be assumed that, like other starch staples, they would be internally diverse genetically, yielding large numbers of cultivars reflected in lexical polytypy. This article explores why this does not appear to be so for sago palms ( Metroxylon sagu), managed by the Nuaulu of Seram, eastern Indonesia. The economic and cultural significance of the sago palm for the Nuaulu, as for much of Maluku and lowland New Guinea, is immense; but the extent to which humans have managed it has been underestimated, it once being widely accepted that reliance on sago was inversely correlated to the development of conventional agriculture. Nuaulu spend about 32 percent of their total subsistence effort engaged in sago extraction. However, given its overall significance as food, in work budgets, as a multi-purpose natural product, and in cultural imagery, the level of formally codified genetic diversity is low. The hypothesis is examined that managed sago palms do not readily lend themselves to the generation of a large number of stable cultivars, and that this is related to modes of reproduction, longevity and single lifetime flowering, and to extensive reliance on vegetative propagation and forms of tenure and husbandry.
