Soil erosion risk assessment is an essential foundation for the planning and implementation of soil and water conservation projects. The commonality among existing studies is that they considered different indicators (e.g., rainfall and slope) in order to determine the soil erosion risk; however, the majority of studies in China neglect one important indicator, namely the slope aspect. It is widely accepted that the vegetation and distribution of rainfall differs according to the different slope aspects (such as sunny slope and shady slope) and these attributes will accordingly influence the soil erosion. Thus, existing studies neglecting this indicator cannot reflect the soil erosion well. To address this problem, a flexible soil erosion risk assessment method that supports decision makers in identifying priority areas in soil and water conservation planning was developed in the present study. Firstly, in order to verify the impact of the slope aspect on soil erosion, field investigations were conducted, and its impact on the characteristics of the community in the study area was analyzed. Secondly, six assessment indicators were selected, including slope gradient, precipitation, NDVI, land use, soil texture and slope aspect. Next, a developed multi-criteria decision analysis (MCDA) method based on the Choquet integral was adopted to assess the soil erosion risk. The MCDA method, combining objective data with subjective assessment based on Choquet integral, could solve the weight problem encountered when using the quantitative method. The parameters required can be modified according to the soil erosion types, assessment scales, and data availability. The synergistic and inhibitory effects among the soil erosion parameters were also considered in the assessment. Finally, the soil erosion risk results in the Xinshui River watershed revealed that more attention should be paid to the slope of farmland and grassland during the planning and management of soil and water conservation projects. The methodology used in the current study can support decision makers in planning and implementing soil and water conservation measures in regions with different erosion types.

Studies have pointed to a positive relationship between farmers' active engagement in watershed management (WM) and soil and water conservation practice adoption. If farmers' involvement in WM leads to more conservation, what predicts WM participation? This study seeks to answer that question through binomial logistic regression analysis of data from a survey of 6,006 Iowa farmers conducted to support the implementation of the Iowa Nutrient Reduction Strategy (NRS). Results indicate that public and private sector information sources, awareness of and attitudes regarding nutrient loss reduction strategies, farm contiguity to water bodies, and cost-share and technical assistance were positive predictors of farmers' engagement in WM, while lower agronomic self-efficacy, farm press as an information source, greater age, and higher farm sales were negative. Findings point to several potential actions to improve farmer involvement in WM: (1) more effectively engage with the farm press to disseminate information about the benefits of WM, (2) increase outreach to larger-scale farmers, and (3) focus on nutrient loss management capacity building. Further, a continued emphasis on awareness and attitudes related to the NRS and related actions, such as watershed management, may guide efforts to recruit farmers into watershed groups to help improve soil and water conservation outcomes.

Abstract BackgroundLand degradation in the form of soil erosion and fertility depletion is the major environmental problem in Ethiopia. However to curb this problem, Soil and Water conservation (SWC) measures are commonly practiced in many rural parts of Ethiopia. This study was conducted to assess the effects of SWC measures on selected soil quality indicators in Ejersa Lafo District. For this study two peasant associations (kebeles) were selected from the district based on the severity of soil erosion and information on SWC practices. A total of 12 composite soil samples from soil 0 to 20cm depth from two sub watersheds with SWC and without SWC practices at Jamjam laga batu and Koriso Odo guba from three landscape positions (upper slope, middle slope, and bottom) were collected. All the soil samples were analyzed following the standard and recommended procedures in Ambo University chemistry laboratory and subjected to ANOVA using the SPSS computer program. ResultMost of the selected soil physicochemical properties were affected by watershed management intervention. Comparing the two farmlands, the highest bulky density of 1.37gcm-3 was observed from unconserved farmland. The results of the study also showed higher values of Soil electrical conductivity (EC), Total nitrogen (TN), Cation exchange capacity (CEC), Soil Organic matter (SOM), Organic Carbon, Available Phosphorus (Av. P) and Available Potassium (Av. K) in conserved land and those all significantly varied between farm plots. On the other hand, Sandy, pH, SOM, TN, Av. P and Av. K values were significantly affected (p<0.05) by slope and all increased from upper (>30%), middle (15-30%) and lower (8-15%). ConclusionThe contribution of watershed management intervention to improve soil physicochemical properties is significant in the study area as it improved some of the selected soil physicochemical properties of soil. Furthermore, efforts are required to enhance community adoption towards soil and water conservation. Additionally, further research has to be carried out on socio-economic aspects and impacts of the intervention on crop productivity for better understanding of the sustainable use of the land and to make a comprehensive conclusion.

Abstract Background The costs of soil erosion are worsening in developing countries. In recent decades of Ethiopia, government sectors and different organizations are working on watershed management campaigns. Despite achievements, soil loss from cropland was not reversed to the productive limit. Therefore, this study attempts to provide information on appropriate sites for level Fanya juu terrace in croplands located in Sodo watershed, central Ethiopia. Methods A spatial layer of soil loss, land use/land cover, slope, and topographic wetness index was managed using a multi-criteria decision analysis (MCDA) system. The suitability class of each layer was made based on the national guideline for soil and water conservation published in 2016. Then the analytical hierarchy process was used to obtain the relative weight of each layer. Finally, the suitability map was generated using the weighted combination method. Result The result shows that 5.5%, 3.2%, and 40.8% of the study area was highly, moderately, and less suitable for level Fanya juu terrace. The remaining is not appropriate at all. Among ground-truthing points collected on an existing terrace, 95% falls into a less suitable class. Assertively, the MCDA provided imperative information. According to pieces of evidence from level Fanya juu terrace, soil loss is estimated to be reduced by 77% in areas highly susceptible to soil erosion. Conclusion Appropriate soil and water conservation measures unto applicable place is a central part of watershed management campaigns. In long run, this could be effective where farmers’ acceptance, proper execution, and regular maintenance of the structure are kept sustainable. In general, procedure followed and results found in this paper can enable an informed decision on farmer’s managed cropland to tackle soil erosion and boost productivity.
