摘要

This paper explores the idea of hybrid knowledge by combining anthropological research with soil science to investigate orthodox assumptions about shifting cultivation among the Wola highlanders of Papua New Guinea. It is commonly assumed that shifting cultivation exhausts soil fertility rapidly, leading to the relocation of settlements and gardens. However, in Wolaland, farmers can maintain soil fertility without needing to relocate. Evidence from this research suggests that chemical properties ofsoil fertility, such as nitrogen, potassium, and organic matter, decline after cultivation, and that phosphorous is always low. Whatever, local soil-management measures allow farmers to cultivate non-perennial crops semi-permanently through incorporating compost from short grassy fallows into 'soil mounds,' with sweet potato as a staple crop. As a result, farmers are able to avoid long-term fallowing, and the Wola have developed sustainable cultivation regimes in land often considered marginal.
