"Soil erosion is a critical problem affecting rural livelihoods in Ethiopia. Large\r\nnumbers of studies have been undertaken to identify critical areas of soil loss and prioritize\r\nconservation options. With the advancement of geospatial analysis techniques, the use of spatially\r\ndistributed soil erosion assessment options has become increasingly common. The lack\r\nof database and documentation related to soil erosion assessment undermines coordination\r\nleading to duplication of efforts and in some instances generating contradictory results. The\r\npurpose of this study is to (1) review existing knowledge related to the extent and spatial\r\ndistribution of soil erosion, (2) document the associated methods employed to assess soil erosion,\r\nand (3) assess the spatio-temporal dynamics of soil erosion and the determinant factors\r\nin Ethiopia. The review shows that there are about 170 peer-reviewed papers published in\r\nscientific journals related to soil erosion in Ethiopia. In those scientific articles, 15 different\r\napproaches were used to assess soil loss and sediment yield at different scales. Considering\r\nthe data set, soil loss rate in Ethiopia varies between 0 and 220 t ha–1 y–1, and sediment yield\r\nranges between 2 and 70 t ha–1 y–1. Based on the database, the national average gross soil erosion\r\nrate is estimated to be 38 t ha–1 y–1, while the net sediment yield is about 26 t ha–1 y–1.\r\nGenerally, the observed gross soil loss is slightly lower than the mean value from cultivated\r\nlands reported in previous estimates (42 t ha–1 y–1) by Hurni (1993). The estimate made using\r\nthe Revised Universal Soil Loss Equation gives the highest soil loss (51 t ha–1 y–1), while that\r\nbased on field-survey approaches gives the lowest (20 t ha–1 y–1). The highest average net soil\r\nloss rate (40 t ha–1 y–1) is obtained using plot-level measurements, while the lowest (18 t ha–1\r\ny–1) is obtained using the AGricultural Non-Point Source pollution model. The highest average\r\nsoil erosion rate is observed in the moist agro-ecological zone (57 ± 7.8 t ha–1 y–1), while\r\nthe lowest is obtained in the submoist (23.6 ± 2.7 t ha–1 y–1) following the arid zone (28.8\r\n± 6.5 t ha–1 y–1). The wide range of soil erosion estimates imply spatio-temporal dynamics of\r\nsoil erosion in the country, which is mainly a reflection of heterogeneity of the various sites,\r\nmainly associated with different values of cover and management factors. Such knowledge\r\ncan enable making informed conservation decisions by focusing on critical hotspots."^^ . "2022-03" . "77" . "2" . . "Soil Water Conservation Society"^^ . . .
