Metrics details Abstract The economic importance of gaharu is assessed in three villages on the Bahau River in north-central Borneo to gain insights about the incentives for harvesting and management of a valuable nontimber forest product. Three indicators of economic value—level and proportion of income, returns to labor, and proportion of gaharu collecting households per village—are used to demonstrate the multiple incentives that NTFP income can generate. The concept of incentive logic is developed as an analytical technique to show how economic values can be linked to incentives for different types of management actions. The article discusses how incentives from gaharu income were most likely linked to the stake local people had in the resource, their preferences about which forest product to harvest, and their willingness to engage in collective action. These incentives contributed to sustainability to the extent they induced actions that reduce threats to the resource. This is a preview of subscription content, log in to check access.
