Scénario socio-économique et écologique des changements de l’occupation des terres au Bénin

This study appreciates the dynamic of land cover in a faraway or middle future. It is based on a combinatory approach that integrates spatial remote sensing, geographic information system and cellular automata techniques. Landsat TM of 1986, ETM of 2000 and NigeriaSat1 of 2006 images were used for t...
