Important sources of erosion threats were identified in the survey area. Data was collected from household respondents through questionnaires, interviews, target group discussions, and observation. Percentages were used for evaluation. The household samples were examined using software known as SPSS-20. The results of the analysis were interpreted using words, figures, and tables. Numerous factors, such as deforestation, high summer rainfall, topography, overgrazing, inadequate cultivation methods, plot slope, low contour farming practices, cleaning the farmlands rather than mulching after crops were harvested, and excessive cultivation, contributed to soil erosion in the area. The two most prevalent types of erosion in the survey area were rill erosion and gully erosion. The study found that the primary factors influencing the physical SWC structures were rainfall intensity, farm plot location, animals, lack of ground rules to maintain the practiced SWC structures, awareness, and farmland scarcity.
