Abstract:
Sand encroachment is one of the main problems threatening the agricultural production in some parts of Sudan, particularly in Omdurman locality. As the accumulations of sand dunes move, they bury villages, roads, oases, crops,market gardens, irrigation channels and dams, thus causing major material and socioeconomic damage .The integration of remote sensing and geographic information system (GIS) prove to be reliable tools to monitor the sand encroachment processes. It can be seen, frorm this disertation, that there is a decrease in sand encroachmen .This is drawn from the fact that urban development and areas covered by vegitation increased within the specified time span (1987 to 2013).
