Now a days, land degradation has emerged as a significant threat to the promotion of green economy, wellbeing of the ecology and ensuring food security. To counteract such a problem, Scaling up SLM technologies is a drastic solution. It is with this grand theme that this study was conducted in Tehuledere Woreda in three surrounding districts (Amumo, Kundimeda and Messal) taking the vulnerability of the area in to consideration. It shade light at identifying the factors hindering the adoption of SLM technologies and, the role of SLM technologies to ensure food security, and assessing the causes of food security in the context of SLM in the study area. The data used were obtained from both primary and secondary sources. The primary sources include structured questionnaire survey and focus group discussion methods. A total of 193 households were interviewed and their responses were interpreted. Scientific reports and conference proceedings were used to support the primary data. Descriptive statistics method was used for analyzing among farm land size, household, topography, erosion status and the adoption of soil and water conservation practices. The results indicated that farm land size, educational status of household head, slop of the farm land, lack of awareness, lack of adequate rain fall, financial constraints and distance to the farm plot from household home were among the major factors that negatively influence adoption of SLM in the study area which resulted in food insecurity. Furthermore, applying cost effective technologies which are suited for different topography such as manure, stone bundles, check dams, planting trees, etc. are recommended to be adopted effectively to ensure food security. Finally, lack of rainfall, land degradation and soil erosion, small land size, and limited status of SLM technologies are found to be causes of food insecurity in the context of SLM. As land is the main stay of the life in rural areas, efforts should be exerted for successfully scaling up of SLM technologies.
