Description
Summary:This study aimed to map and analyze the patterns of environmentally vulnerable regions to land degradation in the Omo-Gibe River Basin. The study used GIS techniques to map land sensitivity to degradation. The multifactorial approach-MEDALUS method, which used three quality indicators-soil, climate, and vegetation and nine parameters were used. About 48% of the basin was highly vulnerable to land degradation, and 36% showed clear signs of degradation. 15.8% of the area had a low potential for land degradation. Implementing proper land management strategies should focus on severely degraded areas to achieve sustainable agriculture and hydroelectric energy production.
