International audienceThe diachronic analysis of aerial photographs concerning the coastal geosystem of Essaouira points out a quick morphological evolution such as in around thirty years, except the states of surface, general form, that of the dunes as well as their distribution were changed in a consistent manner.Three notions underline environmental correlations : the geosystem, the desertification and the modes of anthropisation. Here on stereoscope Bosch and Lomb in CEREGE, the mapping is carried out from aerial photographs IGN in 50 000th, mission n° 17 of August 10th 1953, in the field of the visible, for the first one, and from aerial photographs IFN in 20 000th, mission n° 852 of December 1984, in the field of infrared, for the sec...
