Summary : Since the Convention on Biological Diversity, the evaluation of varietal richness and its inherent management practices have become prerequisite tasks for in situ conservation. The participative method we are implementing in Sori village (Benin) on cowpea (Vigna unguiculata L) is consistant with such expectations. Basing the estimation of landrace richness on their local names, the participative approach used in this study made it possible to inventory 14 landraces in Sori. Ten mega-practices contributing to maintaining and/or enhancing the pool of landraces were inventoried, described and evaluated according to criteria such as the diversity of use, the optimization of farm resources and anti-risk strategies. For each practice, an aptitude value for conservation was calculated. These approaches revealed that botanic treatments, seed multiplication and cultural association are the most important practices according to value markers of agricultural practices. This study made it possible to test the use of particular a methodology in evaluating peasant management practices of agrobiodiversity. It also highlighted how local varieties are taken into account in the production systems and the agricultural policies of biodiversity conservation. |
