  abstract = {{T}his study aimed at contributing to the sustainable management of yam ({D}ioscorea sp.) diversity. {I}t was carried out in northern {B}enin on 220 farms and in 8 villages. {T}he main hypothesis considers that varietal diversity is influenced by ethnic diversity and the market. {R}esults show that diversity remains high with 182 landraces observed in the fields. {T}he study underlines the major role of cultivation practices and of socio-cultural determinants that depend on the history of each ethnic group. {I}n relationship to this point, the {B}ariba, the {N}ago and the {G}ando, who have cultivated yams since remotest times, still remain the best social vectors of diversity. {C}haracteristics of villages, such as links with the geographic and social levels, act on the level of diversity. {T}he reduction of diversity brought about by market development is not confirmed. {F}acing the complexity of diversity determinant factors, the study concludes that the success of an in situ conservation policy will depend on the difficult choice of the area where it is carried out.},
