The necessary data were generated principally from primary and to some extent secondary sources to answer the research question. Thus, household survey involving 290 households was done using questionnaires. Multinomial logit and endogenous switching regression models were employed to achieve the above objectives. In addition, the study employed one stage approach in which both technical efficiency and factors of inefficiency are analyzed simultaneously. The result of endogenous switching model reveals that adoption of SWC practices have a positive and significant impact on household’s food security. Moreover, the result of the study also shows that households adopting all conservation practices are more food secure than other alternative adopters. Failure to adopt SWC practices leads to lower food security status. According to the multinomial logit result, technology adoption is positively related with education/ training, soil fertility, access to extension services, land size and livestock holding. But adoption of agriculture technologies has negative and significant relation with non-marriage status, and distance to the input and out market. On the other hand, study revealed nearly half of households produce with only 50% percent efficiency and there is a room to improve production efficiency. Slope of farmland, livestock possession, agricultural tools ownership and SWC participation are factors that significantly determine efficiency. Increased effort on physical SW conservation activities along with biological, investing more education and training, improving infrastructure/access to services are key recommendation in improving production efficiency and food security are stemmed out of the study.

My honest and deepest gratitude to my advisor Dr. Degefa Tolossa for sharing his invaluable comments, suggestions and advices. I really appreciate his commitment in carefully reviewing my drafts and his ability to point out detail gaps within the thesis and suggestions for improvement. Each moment I sit down with him I get a great deal of knowledge and critical advices which I used it not only for enhancing this thesis but found them extremely useful for my individual and academic personalities. Special thanks to my wife Abaynesh Tegene and children; Dibora Zerihun, Samuel Zerihun and Eyana Zerihun for the energy and enthusiasm I obtained with their understanding of time I spent on my study and encouragement. My sincere thanks to Dr. Solomon Tsehay who encouraged me to attempt a research on this theme and gave me pieces of advices on some technical matters on the paper. Thanks to FEWS NET colleague, Mandefro Mekete for unreserved support with his advises and used his access to subscribed references to provide me necessary materials. Thank you, Getachew Abate for your GIS inputs, on this thesis. I am grateful to Ambassador Kassa Teklebrehan and Zewditu Tegene for their critical and useful intervention that enabled me to maintain my study. I take this moment to extend my gratitude to FEWS NET SMT for encouragement, positive attitude for my master‘s study and finance support for the courses of the study. Last but not least, I would like to thank staff members of Degem Woreda Agriculture Office in particular Dereje and Eshetu Hunde for their continuous moral support in my research work.
