Studying the Natural Characteristics and Changes in Land Use in the Hammad Basin Using Geographic Information Systems and Remote Sensing During the Period (1984-2015)

The vegetation cover is one of the most important natural wealth and resources, especially in the ecosystems of the dry areas, which suffer from the fragility of the ecosystems, the deterioration and the inability to restore their natural balance without human intervention. The vegetation cover plays an important role in protecting the soil from erosion, as it works on the flow of rain on Soil granules, as it is considered as a protective buffer to reduce the atomization and volatilization of the soil, and reduce the movement of sand and its encroachment on agricultural lands, and the shade of plants plays a “prominent” role in reducing evaporation and maintaining soil moisture. This study aims to study the natural characteristics and changes in land use in the Hammad Basin using geographic information systems and remote sensin
