Background:The reciprocity in the exchanges between the local populations who hold the authentic traditional knowledge that they share with the conservation biologists was not sufficiently taken into account. For fairness and justice in these exchanges, the Nagoya Protocol on Access and Benefit-sharing was established. However, there is a lack of information on access and benefit sharing in unfunded ethnobotanical studies in Africa (MS and PhD research). Traditional knowledge on Detarium microcarpum Guill. & Perr. a multipurpose Fabaceae, unfortunately threatened with extinction, exists in Adamawa, Cameroon. Thus, in relation to a Master Research thesis without funding, a study was dedicated to this plant.Methods: Ethnobotanical methods have made it possible to test the following hypothesis: for an equal number of men and women, the points attributed according to gender to the categories of reciprocity experienced during an ethnobotanical study without funding are equal. Thirty available informed consent volunteers (15 men and 15 women) with knowledge on this plant participated in this study.
