Borassus akeassii called" r nier " in French marks the South-Western landscape of Burkina Faso and plays an important role in local people livelihood. The present article is about this species uses and its socio-economic roles. Investigations have been made in three villages and in Banfora markets. The interviewed people were the villagers, extractors and retailers of sap, the outfitters and retailers of handicraft products. Some quantifications of sap and handicraft objects produced and sold have been conducted with the actors of the sector. Financial fallout has been also studied taking into account the high and low production periods. The results revealed that five parts of the tree were used as food, six as medicine and three in handicraft. Product prices varied with the period of production, the category of the seller and the object dimension. In dry cold period, from November to February, sap trading yielded net incomes of 277347 ± 94 653 FCFA for the extractors whereas the incomes amounted to 319 368 ± 163 969 FCFA from March to October. A craftsman could get a net income of 277 933 ± 2 787 FCFA during the high production period and 110 383 ± 25 371 FCFA during the low production period. Due to such an importance, there is a need for research program on the resource base, the improvement and management of the species. A better organization of the actors of the sector will improve their access to market information, to know the requirements of the market and to be aware of the impacts of product quality on the profit of the actors of the sector.
