Summary: Although farmers' perceptions on soil erosion in the Eastern and Northern Regions of Ghana are time and site-specific, a majority of them still consider soil erosion as a serious problem. They attribute severe erosion to over-cultivation, deforestation, and heavy rainfall events. Farmers' perceptions play a crucial role in developing effective soil management strategies in the study area.

Summary: Soil erosion by water poses a serious threat to agricultural productivity and the environment, and climate change will worsen this problem. However, existing studies have limitations in applying climate scenarios to soil erosion models and considering the role of changing land use. This study addresses these gaps by developing a comprehensive method to select suitable climate models and examining the impact of different land use choices on soil erosion. The findings suggest that winter wheat is the most economically and environmentally viable land use choice to mitigate future soil erosion.

Summary: Proper simulation of storm intensification is critical in projecting crop yield, surface runoff, and soil loss under climate change conditions. This study developed multiple climate scenarios and integrated different GCM models, improving the prediction of crop yield, runoff, and soil loss from various cropping and tillage systems under climate change conditions.

Summary: This study investigated the intersection between empirically derived and farmers' perceived soil erosion risk in a medium-sized catchment on the Ugandan side of mountain Elgon. Farmers' perceived soil erosion risk was generally lower than the model estimates. While 95% of farmers recognized soil erosion as a problem, only 65% implemented some form of Soil and Water Conservation (SWC) measures on their land.

Summary: Poor agricultural practices can lead to soil erosion and reduce agricultural productivity among small-scale sub-Saharan African farmers. However, information on these practices is often not well documented, making it challenging to develop mitigation strategies. A fine-scale agricultural survey in the Sio Malaba Malakisi River Basin (SMMRB) between Kenya and Uganda found that many farmers lacked soil and water conservation practices, but a significant number implemented one or a combination of practices. Farmers' perceptions on soil erosion and loss of soil fertility were found to be positively correlated, suggesting the importance of reducing soil erosion to maintain soil fertility. This study provides a baseline for improving current soil and water conservation measures and highlights the need for further research on the efficiency of these practices and farmers' knowledge and perceptions.

Summary: This study presents the development and verification of an improved and cost-effective flume apparatus and corresponding testing methodology. The equipment and testing methodology produced erosion curves with repeatability that were superior with respect to their initial linear and transition portions. Recommendations are made regarding the adequate interpretation of the testing data and the selection of the ideal elapsed time for soil loss analysis.

Summary: This study evaluated the impact of roads on surface runoff, erosion, and sediment yields after a wildfire, finding that predictive models provide reasonable results. The study used GeoWEPP model to simulate erosion and sediment delivery, concluding that roads influence sedimentation processes and present opportunities to detain eroded sediments.

Summary: This study identifies soil erosion susceptible zones in the Sobha watershed of West Bengal, India, using machine learning algorithms and remote sensing data. The study reveals that elevation, drainage density, and vegetation index are the main factors contributing to soil erosion. The random forest model performs best in predicting erosion. The findings can guide the implementation of effective policies to mitigate soil erosion.

Summary: A new modeling platform was developed to simulate sediment production and transport in agricultural landscapes. The model's performance was tested in watersheds at the Oklahoma and Central Plains Agricultural Research Center, and it successfully captured the complex behavior of sediment under different management practices. This study is expected to advance the current approaches to estimating soil erosion by bridging scale differences and considering large-scale effects.

Summary: The study aims to predict soil erosion in the Lattakia Governorate using the WEPP model and compare it with the RUSLE. Results show that most locations experience slight to moderate erosion, while some face severe soil erosion hazard. The correlation between the WEPP model and RUSLE is good, indicating a reliable predictive capability for both models.

Summary: A non-linear regression model was developed to estimate temporal adjustments of K-i, K-r, and tau(c) considering different crops and management practices. The predicted adjustments showed good agreements with sample data and WEPP simulations, indicating their potential use in soil erosion models.

Summary: This study utilized a methodology that combined narrative scenarios and land-use change modeling to develop three contrasting spatially explicit land-use change scenarios in a rural watershed heavily affected by water erosion in Morocco. By interacting with local stakeholders and incorporating their knowledge, the research laid the foundation for building sustainable strategies to address soil erosion issues in Mediterranean catchments.

Summary: To respond to future climatic challenges, it is necessary to evaluate the effects of different cropping and tillage systems on surface runoff and soil loss. This study used climate scenarios and modeling to simulate the impacts of future climate on runoff, soil erosion, and crop production. The results showed that reduced precipitation and increased temperatures would negatively affect farmland.

Summary: Sustainable land management (SLM) is essential for reducing land degradation and desertification, but there is a lack of comprehensive reviews on its spatial distribution, prospects, and challenges. We analyzed data from a global SLM database, academic research papers, and found that dissemination and research on SLM were better in dry subhumid countries with medium scores on the Human Development Index (HDI), while humid countries with low HDI values had lower dissemination and research. Cropland and water erosion were the main focus areas, while other land use types and SLM purposes received less attention. The limited evidence-based SLM dissemination in countries with high soil erosion rates and low HDI scores can be addressed through integrating existing scientific research and SLM databases using the proposed Research Evidence for SLM framework. However, detailed country-specific studies are needed to develop appropriate evidence-based SLM dissemination strategies.
