Book excerpt: Seminar paper from the year 2024 in the subject Nature Protection, Landscape Conservation, grade: A, Mekelle University (Climate change and rural development), course: Climate change, environment and development, language: English, abstract: Land degradation in terms of soil erosion and nutrient depletion affects soil physical, chemical and biological properties; crop yield and income growth particularly crop income. Yet a basic assumption underlying the interventions in developing countries, mostly the degraded agricultural areas, is that adoption of soil and water conservation (SWC) practice has the potential to improve available soil nutrients specially carbon content, crop yield and crop income by reducing soil erosion. Less attention, however, has been given to specifying and linking the effect of adopted SWC practices influences (or specifically, improves) soil nutrients and crop yield; their impact on crop income and the factors influencing them in Ethiopia. Partly to fill this limitation, this review aims to look at the effects of adopted SWC practice in cultivated highlands of Ethiopia; the factors influencing them and their implications for soil and crop yield, carbon sequestration and crop income. Several findings indicated that SWC practices affected to soil bulk density (BD) negatively; and soil reaction (PH), potassium (K), available phosphorus (P), total nitrogen (N), soil organic carbon (SOC), soil organic matter (SOM), cation exchange capacity (CEC), texture, exchangeable sodium (N+), calcium (Ca+2), magnesium (Mg+2), other micro nutrients, crop yield and income positively. In addition, the review paper concerns that adoption of soil and water conservation practices has a positive impact for some agricultural soil and crop productivity, while negative impacts for some others, thus, a dynamic soil nutrient analysis should be more appropriate to improve agricultural productivity.

This book was released on 2017-03-24 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agricultural productivity in the highlands of Ethiopia is threatened by severe land degradation, resulting in significant reductions in agricultural GDP. In order to mitigate ongoing erosion and soil nutrient loss in the productive agricultural highlands of the country, the government of Ethiopia initiated a Sustainable Land Management Program (SLMP) targeting 209 woredas (districts) in six regions of the country. This study evaluates the impact of SLMP on the value of agricultural production in select woredas by using a panel survey from 2010 to 2014. Whereas previous studies have used cross-sectional data and short timeframe field trials to measure sustainable land management (SLM) effects on agricultural productivity, this analysis exploits data collected over four years to assess impact. The results of this analysis show that participation by farmers in SLMP, regardless of the number of years of participation in the program, is not associated with significant increases in value of production. This may be due to several reasons. First, similar to previous studies, it is possible that longer term maintenance is necessary in order to experience significant benefits. For example, Schmidt and Tadesse (2014) report that farmers must maintain SLM for a minimum of seven years to reap benefits in value of production. Second, this analysis finds that value of production, as well as SLM investments, increased significantly in both treatment and non-treatment areas over the study period. Previous research has found that non-treatment neighbors learn from nearby program areas, and adopt technologies similar to programmed areas, which would dilute the impact measurement of program effects (Bernard et al. 2007; Angelucci and DiMaro 2010). Finally, it is important to note that kebeles that were not selected in the SLMP, but are downstream relative to a targeted kebele may receive indirect benefits through reduced flooding, increased water tables, etc. Thus, the impact of the SLMP may be underestimated in this analysis if non-program kebeles are benefiting indirectly from the program.

Book excerpt: Soils represent the result of a complex set of interacting processes and are an integral component of the environment. Yet soils remain the most undervalued and misused of the Earth's resources. This work examines the fundamental importance of soils. Combining practical analysis and interpretation with a theoretical approach, the authors discuss the properties of soils, debate the environmental factors that influence their development, and address their resulting spatial characteristics on a global scale. Examining the impact of environmental controls on soil formation this book also analyzes the role of soils as components of natural environmental systems, and soil-human interactions. A glossary of terms aids the less scientific reader. Adopting macro and micro-scale, pure and applied, spatial and temporal, and natural and human related approaches, this book offers an understanding of soils within an environmental context. As environmental problems, such as pollution, acidification, erosion and climatic change become matters of greater concern, this work offers an understanding for readers across a spectrum of environmentally-related subjects.

This book was released on 2010-08 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the Ethiopian highlands, land degradation has resulted in reduced biomass and soil carbon, thus contributing to the deterioration of soil quality and agricultural productivity. As a result of this fact, conservation of natural resources became a priority of Ethiopian government. Consequently, the practice of establishing exclosures has emerged as one of the mechanisms to restore degraded ecosystems in the central and northern highlands of Ethiopia. This book documents changes in soil nutrient content, soil properties and changes in soil erosion following the establishment of exclosure on degraded communal grazing lands. Moreover, the book presented local communities and experts' perception on the link between soil erosion and land use changes. The study employed a space-for-time substitution to explore the influences of exclosure duration in restoring soil and vegetation. Recommendations that would improve degraded land management were also given.

This book was released on 2016-12-29 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable participatory watershed management is an approach promoted by the Ethiopian government to restore natural resources and agricultural productivity across the country. This comparative study between six watershed programs shows that this approach increases farmers’ food security and incomes (around 50% on average), as well as their resilience to drought and other climate shocks. However, the study also confirms that the nature and scale of impact can vary significantly between watershed programs. The success of watershed management depends on multiple factors from the hydrological profile of the watershed to the local social and economic environment. Tailoring watershed interventions to the local context, associating conservation and livelihoods activities, and providing further financial and technical support to watershed committees are among the recommendations of this paper.

This book was released on 2021-07-22 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seminar paper from the year 2021 in the subject Agrarian Studies, grade: A, , course: Soil and water conservation, language: English, abstract: 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.
