The economic value and sustainable harvest of plants and animals from the tropical forest: Assumptions, hypotheses, and methods
Recent studies of non-timber products from tropical rain forests have emphasized the economic value of these products and the sustainability of present harvests. Many of these studies rely upon a set of untested assumptions about the effects of harvesting upon the forest and the economic value of non-timber forest products in both the marketplace and in the daily life of rural people. These assumptions were formulated as a series of hypotheses during the workshop held in the Regional Community Forestry Training Center, Kesetsart University, Bangkok, in May 1992. The six hypotheses developed by workshop participants will be used to guide future research. As the hypotheses are tested, the data will be used to create a more realistic assessment of the sustainability and economic value of extraction of non-timber products from tropical forests.
