- Abstract
This study aims at analyzing and detecting the evolution and the changes in the lands occupation in the region of M'cif (Msila, Algeria) during 2000-2020. The spatiotemporal survey was conducted using three Landsat satellite images (TM-2000, ETM+-2010, and OLI-2020). A supervised classification technique using the maximum likelihood algorithm has been used for the classification of the use of the lands to generate thematic maps with six main classes. The evaluation of the precision has been applied for each map based on a random method. Moreover, a post-classification technique has been carried out so as to provide a detailed matrix of the changes between 2000 and 2020. Findings confirm that the grassland is subject to very advanced degradation (-130.154 Km2) and that the sand dunes, the agriculturallands, sebkhas, and the urban zone have progressed to + 2.17 Km2, + 16.19 Km2, + 49.66 Km2, +1.21 Km2, respectively. Besides, the study zone is disordered by a rupture of equilibrium between the natural resources and the very high demands of the local people.
