Abstract In Mali, plant cover has been undergoing changes for several decades due to climate changeand human activity. This study contributes to a better knowledge of the floodable pastures andtheir dynamics in the DIN in Mali. The approach was based on a combination of field datafrom surveys and satellite images. The study was carried out on a sample of pastures from thelist of pastures of all managers, listed at the commune level. According to the survey, 99% ofpastoralists have reduced their area due to agricultural practices and 10% to climate changefactors. Twenty-three percent (23%) of pastoralists observed changes during transhumance;bourgou is the dominant pasture grass. There are three types of management besides that ofthe Dioros (Traditional Pasture Managers in the DIN), one distinguishes those of the villagechiefs and the management committees. For a better management of bourgou fields, it isnecessary to invest more in the development of pastoral perimeters, and in the sensitization offarmers, private operators and Dioros for a greater awareness of the degradation of thisheritage and the need for its sustainable management.
