Abstract

This study analyzes the relationship between land use units and natural and anthropogenic factors of the Senegal River delta. Remote sensing and GIS data, Landsat images (1977, 1988, 1999, 2006, 2014) show an expansion rate of vegetation cover (64%) crop areas (6.77%), surface water (4%) and regression of salted areas (74.69%) and dune (15.62%) between 1977 and 2014. Increases are due mainly to irrigation schemes, population growth, protection policies and conservation of natural resources. Regressions are related to the development of the agricultural sector and the importance of rainfall-limiting biophysical processes. The article analyzes the data.
