| Abstract: | Desertification involves several morphodynamic processes which serve as indicators of the highly complex process of desertification and thus play an important role in its monitoring. Ecological degradation triggers off and enhances these morphological activities, which are mainly processes of soil changes, soil erosion, and the transport and accumulation of soils. These alterations of relief and soil result in hydrological changes which have negative effects on land productivity. Both geomorphological and desertification processes are so interwoven that it becomes difficult to differentiate clearly between causes and effects. As the field studies tackled here have been carried out in the sandy regions of western Sudan, special attention is being paid to aeolian erosion and accumulation. Fluvial processes play only a subsidiary role in the processes of desertification there. |
