Abstract:
The paper reconstructs the history of land use in the Senegal River delta (1972-2014), using Landsat imagery. In the study area (which corresponds to the St. Louis, Louga, Podor, Dagana localities), the dynamic of land cover is very particular compared to national and most sub-region dynamics. The resulting maps are presented to denote ecosystem changes. Much of the area is converted dune (27.7%), followed by salt land class (21.1%), growing areas (13.5%). Only 3.2% of land area is varied aquatic vegetation. In general, the mass of land plants fell by 36.3% of area during this period.
