Abstract
The aim of this study was to investigate the potential use of remote sensing and the Geographical Information Systems (GIS) in assessing and monitoring sand encroachment as a desertification indicator in semi-arid environments. The study used the integration of remote sensing and GIS in interpretation and compilation of three satellite images of different periods (1972, 1986, and 1996) with the aid of literature, questionnaire and field check. The study revealed that the area was invaded by sand and the area north latitude 14o 30` is almost totally covered by sand and parts of the Gezira scheme had been abandoned from cultivation due to the buried channels and the destroyed gravity irrigation system. The main result of this study is that the integration of remote sensing and GIS as cost effective tools is appropriate and reliable for monitoring and assessing des
