Land degradation due to wind erosion is common in semi-arid and dry climates. Sandy soils and uncovered lands are prone to wind erosion. Land degradation tends to be common in areas where the topography is hilly and where there is no adequate cover. Unsuitable land use also causes land ...
Land degradation(LD) for the people's livelihoods and climate is one of the key environmental concerns. In LD mapping, measurement, and monitoring at various space and time scales, geospatial technology plays an immense role. Rational synthesis of the role ofremote sensingfor LD assessments is pr...

Understanding the problems of land degradation and seeking long-lasting solutions to these problems should be one of the central concerns of countries such as Ethiopia where agriculture is the mainstay of no less than 85% of the population. To this end, the collaboration of policy makers, resear...
The challenge is further complicated by the climate crisis, whose effects hasten land degradation in coastal, wetland, and especially dryland regions. For example, more frequent and intense droughts accelerate the desertification of once-arable lands, whilesea level riseand flooding increase soil salinit...
