Domestication of Senna obtusifolia could contribute to strengthening food security, empowering people and improving their living conditions, especially women, through the sale of leaves and seeds. However, very few studies have been devoted to the species in Burkina Faso, and it remains poorly known and still grows in the wild. The present study, whose general objective is to determine the state of domestication of Senna obtusifolia, will lay the scientific foundations for its domestication for the well-being of the population. The survey carried out made it possible to gather local knowledge about its domestication. The survey unit was the household. Fourteen ethnic groups were interviewed in 237 households. Domestication of Senna obtusifolia began in the villages of Sissamba and Namissiguima in the northern region, and Loropeni and Kampti in the south-western region. Its domestication would help create jobs at lower cost.
