چکیده
Mapping and quantifying land degradation status is important for identifying vulnerable areas to design sustainable landscape management. This study maps quantifies in the north Gojjam sub-basin of Upper Blue Nile River (Abbay) using GIS remote sensing integrated with multicriteria analysis (MCA). accomplished a combination biological, physical, chemical indicators generate comprehensive assessment. All were standardized weighted analytical hierarchy pairwise comparison techniques. About 45.3% was found experience high very soil loss risk, an average 46 t ha−1yr−1. More than half moderate level biological (low vegetation low organic matter level). In total, 80.2% area characterized as having physical degradation. Similarly, about 55.8% 39% grouped moderate, respectively. The combined spatial MCA chemical, showed that 1.14%, 32%, 35.4%, 30.5% exhibited low, level, has concluded erosion are most sub-basin. Hence, suggests need management practices reduce degradation, enhance content, increase cover
