Land degradation can be considered in terms of the loss of actual or potential productivity or utility as a result of natural or human factors; it is the decline in land quality or reduction in its productivity. It causes running down of soil organic matter and available water for crop growth. Consequently, implementation of soil and water conservation especially level soil bund is supposed to alleviate the impacts of soil erosion and increase agricultural land production and crop productivity. Based on that the effects of level soil bund was evaluated by conducting on-farm study during the cropping season of 2019 in Eba wakeyo kebele, Nejo District, Western Wollega of Oromia Regional State with the objective of evaluating level soil bund on teff productivity and soil properties. The study involves two factor: level soil bund (with and without) was a main plot and the ages of level soil bund was taken as the sub-plots. The treatment (T1=with bund of six year splited in to 7, T= with bund of 4 year splited in to 7, T3= with bund of 2 year splited in to 7and T4= without splited in to 7) with randomized complete block design. The data was analyzed using general linear model procedures and to separate difference between mean LSD (5%) was used. The level soil bund increased the mean value of soil moisture contents at 0-30 cm and 0-60 cm soil depth, the teff (Eragrostis tef) grain yield increased by 22.85% when compared with controlled block and the teff biomass increased by 24.32%. As the wall, it is concluded that level soil bund improves soil fertility, soil moisture status and teff (Eragrostis tef) grain yield and yield components.

Chapter Summaries
1. INTRODUCTION: This introductory chapter sets the stage for the study by discussing the significant problem of land degradation in Ethiopia, particularly soil erosion and its economic consequences. It highlights the importance of soil and water conservation measures, specifically level soil bunds, in mitigating these issues and improving agricultural productivity. The chapter establishes the rationale for the research by emphasizing the lack of investigation into the long-term effects of level soil bunds on teff production and soil properties in the study area. The chapter concludes by stating the general and specific objectives of the study, outlining the key questions the research aims to answer.
2. MATERIALS AND METHODS: This chapter details the methodology employed in the study. It describes the study site, located in the Nejo district of Oromia, Ethiopia, providing geographical context. The chapter outlines the experimental design, including the treatments (different ages of level soil bunds and a control group without bunds) and the experimental protocol using a randomized complete block design. The procedures for soil sampling and analysis are meticulously described, specifying the methods used to assess soil chemical (texture, organic carbon, total nitrogen, available phosphorus, pH) and physical properties (soil moisture). The comprehensive description ensures the reproducibility of the study's methods.
