Non-Timber Forest Products (NTFPs) are important source for sustenance of rural and urban populations. They contribute to food security and poverty reduction. In order to contribute to the knowledge and sustainable management of these products, ethnobotanical data were gathered through semi-structured questionnaires between March and May 2022 in four (04) villages in the locality of Tonga. A total of 92 informants were involved in the study, including 52 women and 40 men. A total of 43 plant species belonging to 42 genera and 31 families used as a source of NTFPs were recorded. Seven major use categories of the NTFPs were identified. Out of these, food and medicine were the most dominant uses. In food categories, Fabaceae and Piperaceae, were the most represented (13% each) families; and the most cited plant species were Gnetum africanum, Tetrapleura tetraptera, Recinodendron heudelotii and, Garcinia cola, while in medicine, Poaceae and Asteraceae were dominant. Ageratum conyzoides, Eremomastax speciosa, Ocimum gratissimum, Cymbopogon citratus and Raphia taedigra were the most used plants in medicine. Out of these species, ten (10) plant species are used in food, 32 in medicine, 6 plants are commonly used in both categories. The species Gnetum africanum (51,1%), Tetrapleura tetraptera (23,9%), Recinodendron heudelotii (21,7%), Garcinia cola (17,4%), Megaphynium macrostachym (18,5%), Cola pachycarpa (13%) are the most sought after in both areas. Trees (69%) and herbs (47%) were widely used. Whereas, leaves were the most solicited organs, and were mostly harvested from the forest (69,56%). Malaria and Stomach ache were the most treated diseases conditions. The most used method for drugs preparation was decoction. While picking (63%) and collection (21%) were the mainly practiced collection. This result constitutes a data base on the importance of NTFPs in the locality of Tonga.
The present study is part of the Home Garden project and Domestication in the Sudano-Sahelian region of Cameroon. The aim of the work is to contribute to the promotion of Moringa oleifera Lam. for its better valorization in Cameroon. An ethnobotanical survey was conducted among 158 stakeholders of Moringaceae in 15 communities in the Sudano-Sahelian zone through the Rapid Participatory Reseach Method (RPRM). The questionnaire is based on the knowledge, practices and indigenous knowledge of the people on M. oleifera. It appears that the leaves and seeds are the most commercialize in the region. The leaves, roots and seeds are the parts used in traditional medicine. Famer’s of the Sudano-Sahelian area of Cameroon treat 19 diseases with the different parts of the plant. Six diseases (dental caries, HIV / AIDS and malnutrition, diabetes, high blood pressure, sore eyes and typhoid) are commonly treated in the study area. The plant would be introduced in the Sudano-Sahelian zone of Cameroon by the Fulani to 17siècle. The Guiziga, Mafa, the Moufou and Toupouri use six criteria based leaves, pods, seeds and trunk to distinguish each trees of M. oleifera. These qualitative criteria can be used baseline data for the morphological characterization of the species. These results can be used as database for the selection of ecotypes solicited by populations.
