Soil erosion risk assessment and treatment priority classification: A case study on guder watersheds, Abay river basin, Oromia, Ethiopia

GIS based soil loss assessment using RUSLE model: A case of Horo district, western Ethiopia

“…As a result, agricultural production is declining in the study area due to nutrient loss from topsoil [ 32 ], which adds pollutants to the downstream of Finca'a, Amerti, and Nashe water bodies and causes dam sedimentation [ 21 , 33 , 34 ] and leads to a problem of reservoir erosion, which agrees with studies by Ref. [ 9 ].…”

“…Likely, as conducted at the Fincha'a watershed, the mean annual soil loss rate was 33.66 ton/ha/yr [ 11 ] which confirms with this result finding. Similarly, at the Gudar sub-watershed, the mean annual soil eroded was 25.23 ton/ha/yr [ 9 ]. These researchers agreed with this result in the area that observed severe soil erosion, particularly at Shambu and Sekelaa, the mean annual soil loss was 25.84–32.27 ton/ha/yr that is more than severe in other areas.…”

“…The level of living for humans is determined by the sustainability of soil for agricultural production, which contributes over 95% to global food security [ 8 , 9 ]. The revised universal soil loss equation (RUSLE) is an empirical model that has been used all over the world to prioritize conservation efforts and predict soil erosion loss using GIS in high-erosional locations [ 5 , 9 , 10 ]. Determining the amount of soil loss, assigning a value to it, and prescribing conservation actions are therefore essential for resource management [ 2 , 11 ].…”

Soil erodibility by simulated rainfall in Latosols

“…Erodibility is variable due to a wide variety of soils with different attributes (Duguma, 2022). It is possible to observe textural differences within the order of the same soil, regarding the Latosols (Santos et al, 2018), this being the most representative order among all occurrences in the Brazilian territory.…”

Soil erosion assessment and identification of erosion hotspot areas in the upper Tekeze Basin, Northern Ethiopia

“…However, most of the previous studies were plot-scale, or small-scale at small-watershed; and were fragmented. Recently, majority of the sub-basin and basin-based soil erosion assessments studies are conducted in Blue Nile Basin [ [26] , [27] , [28] , [29] , [30] , [31] ], and Rift Valley Basin [ 17 , [32] , [33] , [34] , [35] , [36] ], while data on soil erosion status in the Tekeze River basin in Waghimra administrative zone is scarce. Since the basin is home to millions of rural farmers whose economy mainly depends on rain-fed agriculture, estimating soil erosion rates and identifying erosion hotspot areas at basin level is critical for land and water resource management.…”
