“…Then, the experimental fields were grouped randomly within the block, and separate randomizations were made for each block. Slope of the watershed ranged from 0-20% and three slope classes < 9% (lower), 10-14% (middle), and >15% (upper) were considered during block classification [37,38]. The experiment was designed in three treatments: (i) fields treated with soil bund (SB), (ii) fields treated with stone-faced soil bund (SFSB), and (iii) fields without soil and water conservation practices (control, C) in three replications with randomized complete block design.…”

Research-based evidence on the effects of soil and water conservation practices (SWCPs) on soil physicochemical properties and crop yield is vital either to adopt the practices or design alternative land management strategies. Thus, this study was conducted to evaluate the effects of about 10-year-old soil bund (SB) and stone-faced soil bund (SFSB) structures on selected soil physicochemical properties, slope gradient, barley grain yield, and yield components in the Lole watershed, in the northwest highlands of Ethiopia. The experiment consisted of three treatments: (i) fields treated with SB, (ii) fields treated with SFSB, and (iii) fields without conservation practices (control) with three replications at three slope classes. A total of 27 composite soil samples from 0 to 20 cm depth and barley grain yield samples from 27 locations were collected. The soil samples were analyzed for bulk density, soil texture, porosity, soil reaction, cation exchange capacity, organic carbon, total nitrogen, available phosphorous, and potassium. Barley grain yield was analyzed using different agronomic parameters. The result indicated that SB and SFSB positively influenced the physicochemical properties of soils and barley grain yield. The interslope gradient between the successive SBs and SFSBs was reducing. Moreover, the untreated fields showed significantly lower barley grain yield, plant height, and straw biomass. Hence, SB and SFSB practices were found to be effective in changing slope gradient, improving soil fertility, and increasing crop yield. Therefore, this finding is vital to create awareness and convince farmers to construct SWCPs on their farmlands for sustainable land management.

Abstract. In this forum paper we discuss how soil scientists can help to reach the recently adopted UN Sustainable Development Goals (SDGs) in the most effective manner. Soil science, as a land-related discipline, has important links to several of the SDGs, which are demonstrated through the functions of soils and the ecosystem services that are linked to those functions (see graphical abstract in the Supplement). We explore and discuss how soil scientists can rise to the challenge both internally, in terms of our procedures and practices, and externally, in terms of our relations with colleague scientists in other disciplines, diverse groups of stakeholders and the policy arena. To meet these goals we recommend the following steps to be taken by the soil science community as a whole: (i) embrace the UN SDGs, as they provide a platform that allows soil science to demonstrate its relevance for realizing a sustainable society by 2030; (ii) show the specific value of soil science: research should explicitly show how using modern soil information can improve the results of inter-and transdisciplinary studies on SDGs related to food security, water scarcity, climate change, biodiversity loss and health threats; (iii) take leadership in overarching system analysis of ecosystems, as soils and soil scientists have an integrated nature and this placesPublished by Copernicus Publications on behalf of the European Geosciences Union. 112 S. D. Keesstra et al.: The significance of soils and soil science soil scientists in a unique position; (iii) raise awareness of soil organic matter as a key attribute of soils to illustrate its importance for soil functions and ecosystem services; (iv) improve the transfer of knowledge through knowledge brokers with a soil background; (v) start at the basis: educational programmes are needed at all levels, starting in primary schools, and emphasizing practical, down-to-earth examples; (vi) facilitate communication with the policy arena by framing research in terms that resonate with politicians in terms of the policy cycle or by considering drivers, pressures and responses affecting impacts of land use change; and finally (vii) all this is only possible if researchers, with soil scientists in the front lines, look over the hedge towards other disciplines, to the world at large and to the policy arena, reaching over to listen first, as a basis for genuine collaboration.

“…Ethiopia is affected by different environmental challenges, and water-induced soil erosion is one of the keys to finding sustainability to agricultural production and productivity to safeguard food security (Araya et al, 2012); FDRE, 2011. Agriculture is the backbone of the country's economy and sustains the livelihood of about 85% of the population; loss of productive soil by erosion has massive environmental and economic impacts UK, 1999; (Ayalew, 2015).…”

Soil erosion by water is a serious concern worldwide problem and it is difficult to assess its economic and environmental impacts accurately. West Hararghe zone is one of the most erosion-prone areas in the eastern highland of Ethiopia which little attention is given. The objectives of this study were to estimate the magnitude of soil loss rate, assess the change of erosion risk, and elucidate their implication for SWC planning in West Hararghe Zone, Eastern Ethiopia. Applying remote sensing data, the study first derived the Revised Universal Soil Loss Equation (RUSLE) model parameters in an ArcGIS 10.3 environment and estimated the soil loss rates. This model was developed based on the integrated use of precipitation data, Landsat images in 2017, and 2018, terrain parameters (slope gradient/steepness and slope length), soil loss management practice and soil composition in west Harerge Zone, Oromia Regional state, Ethiopia. The estimated total soil loss in the Zone was 47,288,835.17 tons in 2017/18 with a mean erosion rate of 28.62 t ha −1 yr −1. The study area was divided into six erosion risk classes ranging from low to high. About 27.70% (457,687.19 ha) of zone was classified under high to very high soil loss class while the remaining 72.30% (1,194,613.1314 ha) of the zone categorized under slow to moderate soil loss class.
