The review focuses on the importance of soil and water conservation practices on soil properties in Ethiopia. The study conducted in various parts of the country showed that the implemented soil bund reduced annual runoff and soil loss at different rates. Soil and water conservation have improved the soil physicochemical properties on conserved cropland (BD, SMC, infiltration rate, clay content, pH, CEC, av. K, av. P, SOC and TN) than in the adjacent cropland without soil and water conservation measures.
Soil and water conservation, reduce the removal of fertile topsoil and improves soil moisture, which favors crop growth as a result grain yield of the crops were increased at various rates based on agro ecology, crop type and local management practices. In general, the effect of constructed soil and water conservation had clearly showed positive impact on soil physicochemical properties and crop yields. Therefore, to reduce soil erosion sustainably, different soil and water conservation options should be introduced and used considering agro ecology, socio-economic profile and climatic condition of the intervention area.
Soil erosion is one of the several major deteriorative processes which results in soil degradation and declining agricultural productivity in Ethiopia due to dense population, high livestock density and intensive crop production in the area. Soil and water conservation practice is one the mechanism used to reduce soil and associated nutrient loss; thus, reduce the risk of production. Efforts were started through soil and water conservation strategy at a large scale on farmland since the mid-1970 and 1980’s. However, soil erosion still persists and become major threats of the Ethiopian region.

Zusammenfassung der Kapitel (Chapter Summaries)
1. INTRODUCTION: This chapter sets the stage by highlighting the critical role of agriculture in Ethiopia's economy and the significant challenges posed by erratic rainfall, leading to soil erosion and land degradation. It emphasizes the dependence of rainfed agriculture on effective rainwater conservation and the importance of soil factors in determining hydrological properties. The chapter establishes the context for the review by outlining the widespread problem of soil erosion in Ethiopia and the considerable investment made in soil and water conservation schemes, despite mixed results. It finally introduces the review's objective: to examine the impact of soil and water conservation practices on soil properties and productivity.
2. LITERATURE REVIEW: This chapter provides a comprehensive overview of soil erosion and soil and water conservation efforts in Ethiopia. It details the various types of soil and water conservation measures implemented, categorizing them into agronomic, biological, and physical methods. A substantial portion is dedicated to analyzing the role of these practices on both the chemical and physical properties of the soil, examining how conservation techniques influence parameters such as bulk density, soil moisture content, infiltration rate, nutrient levels, and pH. The chapter synthesizes existing research to showcase the positive impacts of successful conservation on soil health and crop yields, while also acknowledging past challenges in implementing these strategies effectively.
