Assessment of implemented physical designs and determinant factors of soil and water conservation measures: Wenago district, southern Ethiopia

Soil erosion and its consequences is one of the major serious problems in Ethiopia. Even though adoption of soil and water conservation (SWC) measures has been underway for the past three decades, the implementation and use of introduced technologies were below the expectation and the problem is still has continued in the country. The study was aimed at assessing the implemented physical designs of soil and water conservation structures in respect to the standards and identifying the major adoption determinant factors in Wenago district, southern Ethiopia. The data for this studywas collected from a survey of 262 total household farmers selected through simple random sampling techniques in the year 2020/21 and the datawas analyzed using descriptive statistics, chi-square and logistic regression model via SPSS and Stata soft wares. Focus group discussion, key informant interview and personal observation were also undertaken to gather data having qualitative nature. (i) About 55.6% of the implemented physical design failed to meet the standards (ii) Adoption of SWC measures were determined by 47.4% of the tested variables (iii) 55.5% of the variables were significantly associated at 5% probability level between adopters and non-adopters in terms of adoption of SWC measures in the study area. Overall, we conclude that construction of conservation structures should be focused on minimizing the observed mismatch of the implemented physical designs against the standards. This study is expected to contribute in achieving sustainable land management schemes, agricultural productivity and smallholder farmers livelihood improvement in international, national, regional and local level and it is strongly recommended that policy makers and technical institutions should address SWC related issues to ensure rural farmers food security.
