Objectif: La relance de la filiere cafeiere suscite un regain d’interet national pour la valorisation de Canarium schweinfurthii ou « Aiele », un arbre a usage multiple dominant des agroforets de l’Ouest Cameroun. Cette etude a pour but d’evaluer la valeur accordee par les populations a ses usages dans le Departement de Bamboutos. Methodologie et Resultats: Cent-sept interviews semi-structurees ont ete menees aupres des producteurs de l’espece dans trois groupements. Des parametres ethnobotaniques ont ete calcules et compares entre groupements. Sept utilisations de l’espece ont ete recensees, les usages alimentaires (27 %), d’ombrage (23 %) et commercial (19 %) sont predominants. Les organes utilises sont les fruits, la resine, le bois, les feuilles et la graine. Les plus fortes valeurs d’usages sont obtenues dans les localites de Babete (VUt = 1,53). Les valeurs d’indice de fidelite (NF) (0-100%) obtenues temoignent de la variation du niveau de connaissance des populations pour cette espece. Conclusion et application des resultats: La presence de C. schweinfurthii dans les plantations cafeieres fournit des benefices tres importants pour l’equilibre de ce systeme a travers ses multiples usages, la diversite des produits fournis et l’importance des services offerts pour la performance du systeme. La variation du niveau de connaissance en fonction des groupements est un atout majeur pour la valorisation de l’espece a travers des echanges de savoirs et savoir-faire inter groupements et au-dela du Departement. Cependant, la degradation des cafeieres au profit des systemes essentiellement vivriers pourrait affecter negativement la representation de l’espece dans l’espace agraire de la region et par consequent la perte des differents services qu’elle offre. L’etude recommande une valorisation des produits de l’espece et une promotion de la domestication a travers des pratiques de gestion favorisant son integration dans tous les types de systemes de production agricole de la localite.

This study aims to evaluate the use value of the species for the populations of the Department of Bamboutos. Methodology and Results: One hundred and seven semi-structured interviews were conducted with producers of the species in three villages groups. Ethnobotanical parameters were calculated and compared between groups. Seven uses categories of the species were identified, among which Food uses (27%), Shade (23%) and Commercial (19%) were predominant. The organs used are Fruits, Resin, Wood, Leaves and Kernel. The highest values of uses are obtained in the localities of Babete (VUt = 1.53). The Fidelity Index (NF) values (0-100%) obtained showed the variation in the level of knowledge among studied populations and village groups. Conclusion and application of results: Presence of C. schweinfurthii in coffee plantations provides very important benefits for the performance of this system through its multiple uses, the diversity of the products supplied, and the importance of the services provided in the system. The variation of the level of knowledge according to populations and village groupings is a major asset for the valorization of the species through exchanges of knowledge and know-how between groups and beyond the Department. However, the degradation of coffee plantations in favor of mainly food –based systems could negatively affect the representation of the species in the agrarian landscape of the region and consequently the loss of the various benefits it offers. The study recommends a valorization of the products of the species and a promotion of the domestication through management practices favoring its integration in all existing agricultural production systems found in the western highlands.
