Abstract

The present research paper aims to study and shed light on the spatial change of vegetation coverage in the Algerian steppe region. The investigation is based on remote sensing and geographic information systems through the analysis of satellite visuals in calculating the vegetation coverage index (Ndvi) for three different periods 1985 and 2022, with consideration to remote sensing and information systems.  Geography is among the most important digital means that work to collect, analyze and study the geographical field in all its dimensions, and it also works to follow up on the changes taking place in it.  The latter shows the most important changes in the vegetation cover in the study area.
