Women's Traditional Knowledge, Use Value, and the Contribution of Tamarind ( Tamarindus indica L.) to Rural Households' Cash Income in Benin. This study examined differences in knowledge, use values, and contribution of tamarind (Tamarindus indica) to women's cash income during the dry season, focusing on seven tribal groups in Benin. Data were gathered using semistructured individual interviews and monitoring, and were analyzed using quantitative ethnobotanical methods. Principal component analysis was applied to describe the use value and use forms of tamarind according to different tribes. Tamarind was found to play an important role in local communities' livelihoods. Overall, 26 different uses were mentioned for tamarind products. Most commonly, the fruit (pulp) was used to make beverages, as a laxative and purgative, and it seems to be the only plant part sold commercially. Bark was frequently used as a medicine to treat wounds, and leaves were used to make porridge and as an antibiotic. Medicinal, cultural, and material use categories were correlated best with the Fulani, whereas commerce was most correlated with Gourma tribes (PCA analysis). There were significant differences for tamarind utilization among the tribal groups, with overall ethnobotanical use values (EUVT) ranging from 10 to 14, and contribution to cash income ranging from 8.8% to 56.4%. In view of its domestication potential, it is crucial that traditional tribal knowledge of tamarind be preserved and integrated into management policies. Further development and research needs for utilization and conservation are improvement of commercialization, organization of market channels, and extent of genetic diversity within and among populations
