Abstract
This study has been conducted in the area between the northwestern part of Gezira Agricultural Scheme and the White Nile to study the problem of desertification as general with the emphasis on vegetation cover degradation. The aim of the dissertation is the focusing on the use of Remote Sensing and Geographic Information Systems technologies as an integrated tool to monitor vegetation cover degradation. The product of interpretation of Landsat Thematic Mapper image (1996) was compared with vegetation map of Harrison & Jackson (1958) to calculate the changes in the vegetation areas as result of desertification . This was verified by fieldwork. Mapping of the land use was made to show the entrance of man and his animal as causes of desertification. Suggestions was made to use Advance Very high Resolution Radiometer data and Normalized Difference Vegetation Index (NDVI) over a series of time for more repetitive vegetation cover degradation, to calculate risk and rate at which degradation occur. Remote Sensing and Geographic Information systems can be used to monitor desertification in other affected states of the country.
