Egypt's Land Degradation Threatened by Urbanization, Salinization, and Wind Erosion.
The article discusses land degradation and desertification in Egypt, focusing on urbanization, salinization, and wind erosion. The researchers used satellite remote sensing to assess these processes, combining descriptive and quantitative approaches. They found that remote sensing data can provide valuable information on landscape features, vegetation, and land use changes, helping to evaluate the current status and risk of desertification. By using indices like the Soil Quality Index and Vegetation Quality Index, they identified areas in Egypt with high sensitivity to desertification. The Nile Valley is less sensitive due to cultivated vegetation, but measures to combat desertification are still crucial for sustainable agriculture, especially in desert oases and wadis. Innovative monitoring is recommended for early control of desertification sensitivity.
