“…This meta‐analysis covers measured and simulated SWC investigations conducted in Ethiopia, which is located in the eastern part of Africa, usually known as the Horn of Africa (Figure 1). Ethiopia covers an area of 1,127,000 km 2 and is geographically located at 3°–15° North and 33°–48° East (Biratu et al, 2023). The elevation of the country ranges from 125 m below sea level at Asal Lake, the Danakil depression of Afar, to the top of the Ras Dejen/Semen mountains at 4620 m a.s.l.…”

“…Several studies have been conducted in Ethiopia to evaluate the implemented SWC structures in terms of sediment trap and runoff reduction Gashaw et al (2021), reduction in soil loss and nutrient loss Herweg and Ludi (1999), generating ecosystem services Biratu et al (2023), and the failure status of the structure Tesfaye et al (2015) in an experimental and simulation approach. Most of these studies showed that implemented SWC structures revealed a positive response, even though technology selection, design, layout, implementation, free grazing, and community acceptance problems significantly affect their effectiveness and sustainability (Haregeweyn et al, 2015).…”

To combat land degradation through conserving soil and water resources, Ethiopia has undergone vigorous implementation of soil and water conservation (SWC) measures, predominantly physical structures. To evaluate the effectiveness of these implemented structures, various researches have been conducted through using both measured and simulated approaches. This study was initiated to analyze the reliability of SWAT‐based simulated studies results on the effectiveness of SWC measures toward erosion reduction potential against the measured dataset using unpaired t‐test statistical analysis. In this study, 123 published papers were downloaded, of which 70 were found to be more related to the objective of the review. After applying four refining criteria, only 43 were found more compatible with the study objective and used for data analysis. Studies conducted by different scholars show up to 98% and 93.50% soil loss reduction effectiveness by SWC measures in measured and simulated approaches, respectively. The simulated SWC measure efficiency output was also evaluated with respect to the ground‐measured data of the same structure within the same agroecology class. Finally, the unpaired t‐test results indicated that the grass strip in the mid‐highland agroecology showed a significant difference from the measured one at a 95% significance level. However, none of the other measures showed significant differences between the measured and simulated datasets. Hence, the SWAT model can effectively simulate the effectiveness of physical SWC measures on soil loss reduction if it is well‐calibrated and validated with sediment yield data. Refining model parameters that can be sufficiently captured and represent biological measures (grass strip), incorporating additional field data for calibration and validation coupled with exploring alternative modeling approaches that efficiently simulate biological SWC was set as a recommendation to obtain an effective biological measure simulation.

“…These might be serious challenges that limit the economic lifespan of dams. As a result, establishing the scienti c basis for actions needed to improve conservation planning and sustainable use of ecosystems, as well as estimating and evaluating the status of changes in ESV, is critical for policymakers and development practitioners (Abera et al, 2020;Biratu et al, 2021;Karimi et al, 2020;Nyssen et al, 2018). Therefore, the objectives of this study are: (1) to analyze the trend of ESV associated with land use and land cover change in the Beles Basin between 1986 and 2019; 2) to quantify the amount and rate of LULC changes undertaken during the past three decades; and (3) to estimate the loss of ESVs from 1986 to 2019 periods because of the LULC changes.…”

The objective of this study was assess the status of ecosystem service values (ESVs) due to changes in land use and land cover (LULC) in the Beles River Basin of Ethiopia to establish the scientific basis for the actionable needs for enhancing the conservation and sustainable use of ecosystem functions. Satellite images of Landsat 5TM (1986), 7ETM+(2002), and 8OLI-TIRS (2019) were used to evaluate the LULC changes over the years. All images were classified using supervised classification technique of a Maximum Likelihood Algorithm (MLA). Accuracy assessments were performed for each reference year. The LULC types were classified with overall accuracy ranging from 89.3–92.1% with Kappa coefficient of 0.87 to 0.9. The classification result indicated a reduction of forests (71.0%), woodlands (11.2%), and grazing lands (1.8%) conversely, an increase of croplands (3568.0%), water bodies (178.1%), and built-up areas (9.4%) over the past 34 years. The total ESVs in the basin were estimated to be US$ 1,085 billion in 1986, US$ 909.4 million in 2002, and US$ 836.5 million in 2019. The percentage losses of ESVs were 22.9% (US$ 249.3 million) over the past three decades. Individual ecosystem service functions, such as erosion control, climate regulation, nutrient cycling, and water treatment, which were among the largest contributors to total ESVs, have also linearly decreased on their values. In contrary, the value of food production ecosystem service function increased dramatically. We conclude that the decline in ESVs evidences the effects of environmental degradation in the basin. Thus, we recommend further studies of sustainable land management (SLM) options that could ensure sustainable ecosystem services in the basin.
