Une étude en vue d’évaluer le potentiel de séquestration du carbone des Agroforêts à base de Caféiers Robusta (ACR) a été menée dans quatre sites contrastés par leurs caractéristiques biophysiques et socioéconomiques, et appartenant à trois bassins de production du café au Cameroun. L’approche méthodologique a porté sur la collecte des données d’inventaires dans 120 ACR de différents âges (30 par site); lesquelles ont permis d’estimer le potentiel de séquestration du carbone de façon non-destructive en utilisant les équations allométriques. Le potentiel de séquestration du carbone évalués ont varié significativement entre les sites, de 67,84±45,41 t C.ha-1 à Ayos à 41,94±15,50 t C.ha-1 à Nkongsamba. Globalement, ces potentiels de séquestration du carbone diminuaient suivant le gradient d’anthropisation des sites d’étude. Les ACR des classes d’âge (années) de [30-45[et de [45-60[ont eu les potentiels de séquestration du carbone les plus élevés pour les Espèces associées (EA) et les caféiers respectivement. Le potentiel de séquestration du carbone des EA endogènes (19,46 t C.ha-1 ) était plus élevé que celui des EA introduites (6,32 t C.ha-1). Ces résultats montrent que la contribution des ACR dans les mécanismes d’atténuation des effets du changement climatique est une évidence qu’il faudrait capitaliser.   English title: Carbon sequestration potential of robusta coffee agroforests (Coffea canephora var. robusta) in production basins of Cameroon A study to assess the carbon sequestration potential of Robusta coffee Agroforests (RCAs) was carried out in four sites, contrasted by their biophysical and socio-economic characteristics, and belonging to three coffee production basins in Cameroon. The methodological approach involves the collection of inventory from 120 RCAs of different ages, (30 per site), which allowed no-destructive estimation of carbon stocks using. The assessed carbon sequestration potentials evaluated varied significantly between sites, from 67.84 ± 45.41 Mg C.ha-1 in Ayos to 41.94 ± 15.50 Mg C.ha-1 in Nkongsamba. Overall, these carbon sequestration potentials decreased along the anthropization gradient of the study sites. RCAs of the [30-45[ and [45-60 [age classes (years) had the highest carbon sequestration potentials for associated species (Eas) and coffee trees respectively. The potential of carbon sequestration of the endogenous EA (19.46 Mg C.ha -1 ) was higher than that of the introduced EA (6.32 Mg C.ha -1). These results show that the contribution of RCAs in climate change mitigation mechanisms is evident and should be capitalized upon.

Objective: Studies were conducted to characterize the Non-Timber Forest Products (NTFPs) from the locality of MayoRey in the North Region of Cameroon for their subsequent domestication.Methodology and Results: An ethnobotanical survey was conducted among 200 people drawn from four ethnic groups (Laka, Lamé, Peulh and Toupouri). This study has identified 107 plant species including 54 species food (vegetables, fruits and traditional drinks). The species Dioscorea bulbifera, Burnatia sp., Parkia biglobosa, Detarium microcarpum, Adansonia digitata, Vitellaria paradoxa, Ziziphus mauritiana, Ximenia americana and Vitex doniana were identified as major species of this town, due to their socio-economic importance. Plant parts used in the diet are descending fruits (53.70%), seeds (25.92%), leaves (22.22%), tubers (16.66%), the flowers (3.70%) and other (3.7%).Analyses on food uses indicates that 40 respondents use them as recipes involve fruits and 11 use them to prepare sauce. Three (3) species are commonly used for the preparation of pap, 8 species for the preparation of cuscus and 3 species for the preparation drink. Conclusion and application of results: The exploitation of these species remains traditional, sometimes leading to overexploitation of the resource and therefore a loss of biodiversity. For sustainable management of these resources, domestication of preferred species could be considered.
