文摘

•: Soil erosion is the most important land degradation problem in the Blue Nile basin.
•: A new methodological framework was applied to prioritize erosion-prone areas.
•: The basin experiences high soil loss rates with large spatial variability.
•: Erosion risks are strongly linked to population density.
•: Targeting 77.3% of erosion-prone areas could reduce the basin's soil loss by ca. 52%.
