  Direct-use values of woodland resources consumed and traded in a South African village

  摘要：

  This paper examines the contribution of secondary resources harvested from a savanna ecosystem to household income in Thorndale village, South Africa. The valuation of these resources provides a key tool for adopting sustainable development practices. The study shows the relevance of the dependence of rural people on secondary resources and implications for social and economic equity. Fuelwood, edible herbs and thatch grass contributed 80.6% ($492.53) of the total gross direct-use value ($559.46) of all the resources per household per annum. The net direct-use value of eight directly harvested resources was $455.11 after accounting for the opportunity cost of labour. The value of secondary resources traded amounted to $126.62 per household, equivalent to 22.6% of values from direct consumption, suggesting a high degree of dependence of villagers on natural resources harvested for household consumption. There were high relative direct-use values for fuelwood (44%) and edible herbs (25.9%) reflecting the high energy requirement, and substitute for cultivated vegetables, respectively. It was generally perceived that resources were in short supply probably due to the level of dependence, and as a coping strategy.
