Evaluating soil erosion and factors determining farmers’ adoption and management of physical soil and water conservation measures in Bachire watershed, southwest Ethiopia

Soil degradation due to erosion, which emanates from improper land management, has been one of major challenges affecting agricultural production and food security. To control soil erosion, soil and water conservation (SWC) measures including soil and stone bunds have been developed and adopted. How...

To control soil erosion, soil and water conservation (SWC) measures including soil and stone bunds have been developed and adopted. However, little is known on the impacts of SWC techniques in Africa. Objective of this study was to assess soil erosion and analyze effect of physical SWC measures on cropland productivity. Data were collected using focus group discussion, key informant interview and survey of 169 farm households (122 adopters and 47 non-adopters of physical SWC). Farmers were responded on soil erosion (rill and gully) and its impacts, long existed indigenous erosion mitigation measures as well as effects of introduced physical SWC techniques such as soil and stone bunds. Descriptive statistics and binary logistic regression model were used to analyze data. Based on visible erosion features such as rills and gullies, about 92% of respondents indicated that soil erosion is a major problem on cultivated land, where 64% of the farmers abandoned part of their plot due to exhausted soil fertility and gully development. About 97% of the farmers perceived that soil erosion reduces crop production. Traditional drainage ditch, grass strip and contour furrow are common indigenous SWC measures. More than 86% of the respondents believe that the introduced physical SWC measures (e.g., bunds) reduce erosion and improve crop production. Family size, participation in technical training, access to extension service, the perceived land tenure security, slope of the plot, and perceived severity of erosion had significant (p < 0.05) and a positive association with adoption of introduced physical SWC measures, while farm size had significant (p < 0.05) negative relationship. Increasing knowledge and skill of farmers, providing technical and resource supports and implementing appropriate policy could help sustainable land management that ensure environmental quality and food security in the study area as well as in the other areas having related biophysical and socioeconomic settings.Bafe BetelaKebede WolkaElsevierarticleSoil erosionSlopeSoil bundsAgro-ecologyIndigenous techniqueEnvironmental sciencesGE1-350ENEnvironmental Challenges, Vol 5, Iss , Pp 100348- (2021)
