“…The main causes include erosive high intensity tropical rains, rugged steep topography, extensive deforestation for fuel wood, expansion of cultivation into unsuitable steeply sloping and erosion prone areas, high population pressure and the lack of integrated catchment management (Zeleke, 2000;Bewket, 2002;Nyssen et al, 2004;Mekonnen et al, 2014b). Therefore, a holistic approach is needed to tackle soil erosion in the region (Mekonnen et al, 2014b;Lanckriet et al, 2015;Nyssen et al, 2015;Tesfaye et al, 2015). Soil and water conservation (SWC) structures provide a practical means for reducing soil erosion, enhancing the rate of sedimentation and decreasing local slope gradient (Gebremichael et al, 2005;Mekonnen et al, 2015b).…”
