The study is based on a detailed survey of 77 households using structured interviews, field observation and focus group discussion. Descriptive and chi-square statistics were applied to analyze factors that affected farmers’ perceived soil erosion severity, participation and adoption options. The results revealed that about 79% of farmers perceived soil erosion problem and its consequences and 97.4% of them believed that it can be controlled. Almost all (97.4%) farmers acknowledged the presence of SWC technologies and about 92.2% of them were participated in conservation activities voluntarily. Thus, 93.5% of them realized decreasing rate of soil erosion and 79.9% of them observed an increasing trend in soil fertility status. Consequently, 94.8% of them confirmed the potential of SWC technologies to halt land degradation and improve land productivity. Furthermore, 98.7% of them were willing to adopt with very good adoption judgment and 94.8% of them were willing to continue maintaining constructed technologies in the future. Principally, farmers’ perception of soil erosion, their genuine participation derived from their conviction, and adoption of induced SWC technologies are the decisive elements for the success of watershed management interventions.展开更多
