Effect of Soil Bunds on Runoff, Soil and Nutrient Losses, and Crop Yield in the Central Highlands of Ethiopia

Abstract: The effects of soil bunds on runoff, losses of soil and nutrients, and crop yield are rarely documented in the Central Highlands of Ethiopia. A field experiment was set up consisting of three treatments: (i) barley‐cultivated land protected with graded soil bunds (Sb); (ii) fallow land (F); and (iii) barley‐cultivated land without soil bund (Bc). For 3 years (2007–2009), the effect of soil bunds on runoff, losses of soil and nutrients, and crop productivity was studied. Daily runoff and soil and nutrient losse… Show more

“…Studies conducted in Ethiopian highlands show that soil erosion is seen as a direct result of the historical human settlement in the highlands because of its favorable climatic conditions, political factors and soil fertility (Hurni, 1993;Keesstra et al, 2016). Inappropriate land use, poor farming practices and removal of the natural vegetation aggravate soil erosion and so productivity declines, resulting in food insecurity for smallholding farmers (Adimassu et al, 2014;Angassa, 2014;Bravo-Espinosa et al, 2014). Soil erosion is one of the biggest problems resulting in both on-site and off-site effects.…”

“…Soil erosion is more severe in the sub-Saharan African countries where the population livelihood is dependent on the soil (Sunday et al 2012;Erkossa et al 2015). In the Ethiopian highlands, deforestation for crop production, cultivation of marginal lands, and overgrazing are the major factors that dramatically increased the vulnerability of agricultural lands to rainfall-driven soil erosion (Nyssen et al 2000;Vancampenhout et al 2006;Belay et al 2014;Adimassu et al 2014;Erkossa et al 2015;Addis et al 2016). Intensive rainfall during rainy seasons (June to September) contributes to severe land degradation in mountainous regions, especially on steep sloping and unprotected areas (Addis et al 2016).To tackle the soil erosion problem in the Ethiopian highlands, constructing soil and water conservation structures is considered to be a top priority in halting land degradation and thus to improve agricultural productivity.…”

“…Besides, soil bunds promote rainwater infiltration [17]. However, the adoption of SWC practices is very low [11] [18]. This could be due to farmers' concern for wastage of productive land which could be used for crops, and the lack of integration of physical conservation structures with biological measures.…”
