Spatial dynamic of sahelian vegetation: Analysis of modifications and natural resources disponibility in Burkina Faso, Western Africa

Land cover change is a major driver for ecosystem quality. This dataset highlights the typology of sahelian vegetation degradation stages in general and particulary, describes glacis’s degradation stages through their functional and structural characterization. The study is typically based on the spatial variation of vegetation cover which is determined by combining satellite data, visual interpretations of vegetation cover and field investigations. Taking into account glacis’s degradation stages, phytosociological, dendrometrical, regeneration relevés were done. Soil sample were also taken in each degradation stage of glacis in order to understand the variation of physical and chemical parameters along the vegetation degradation gradient. The following dataset were collected: * Satellites images data * Phytosociological data -180 phytosociological relevés were done according to the geomorphological units -104 phytosociological relevés were done according to the land degradation stage based on vegetation cover variation * Dendrometrical data 104 dendrometrical data were done according to the land degradation stage based on vegetation cover variation. * Regeneration data 104 regeneration data were done according to the land degradation stage based on vegetation cover variation. * Soil data 60 soil samples were taken in each degradation stage at two deph (0-10 cm and 10-20cm)
