Summary: Soil erosion modeling is crucial for soil management and conservation policies. The proposed Spatial Soil Loss Model (SSLM) integrates GIS techniques with USLE and ILSWE models to predict, quantify, and assess soil erosion hazards in the Dakhla Oasis. The study validates the SSLM by comparing its outputs to USLE and ILSWE models, showing promising results for sustainable agriculture in the area.

Summary: This study evaluates the hydrologic and erosive status of eighteen watersheds in south Andaman through drainage morphometric studies. The results show that some watersheds have low levels of soil erosion, some have high levels, and some have moderate levels of soil erosion. Additionally, the study finds that a significant portion of rainfall runoff flows into the adjacent seas, contributing to the growth of mangroves in coastal areas.

Summary: This study examines the factors influencing adoption lag for Soil and Water Conservation Practices among smallholder farmers in the Sio-Malaba Malakisi River Basin border region of Kenya and Uganda. Results show that the average adoption lag of SWCPs in the study area was about 10 years. Factors such as household size, number of accessible markets, access to credit, age of the household head, farm size owned, and tropical livestock units are associated with reduction in adoption lag. Access to off-farm income and household location in Uganda are associated with increased adoption lag of SWCPs.

Summary: To reduce water erosion on arable soils, conservation measures such as contour farming or reduced tillage practices can be applied. This study assesses the impact of reduced and conventional tillage and slope-related tramline directions on runoff and soil erosion rates. Results show that tramlines have strong interrelations with surface runoff, water connectivity, and soil erosion, highlighting the importance of considering tramlines in process-based models for better assessment of soil erosion risk and conservation measure efficiencies.

Summary: Soil erosion is a type of land degradation caused by interactive interaction of various factors. This study evaluates water erosion hazard in the Zhuxi watershed in Southern China using a comprehensive integrated methodology. The results show that the middle part of the watershed has the highest hazard level, with over 60% of the area having high erosion hazards.

Summary: Soil erosion is a major cause of land degradation globally, and this study focused on using the G2 erosion model to predict and monitor monthly hillslope erosion in two agricultural regions of South Australia. By combining high spatio-temporal resolution rainfall data with other datasets, the study aimed to develop a model that realistically represents the complex combination of critical drivers of erosion in the region.

Summary: Nowadays, soil erosion is a global problem that affects natural resources, natural spaces, and agricultural production. Integration of RUSLE equations and GIS techniques allows for mapping of potential and actual erosion, helping to identify areas with extreme erosion levels and stable erosion levels. The integration of GIS techniques with parametric equations provides a simple and cost-effective tool for estimating soil losses and establishing mitigation measures.

Summary: Most of Indonesia's watersheds are highly vulnerable to erosion due to mountainous topography, high rainfall, and erosion-sensitive soil types. However, over the past 40 years, the Indonesian government has implemented systematic soil and water conservation techniques, resulting in positive outcomes.

Summary: The COVID-19 lockdown has led to significant improvement in the water quality of the Kelani River in Sri Lanka. The downstream water quality showed the most remarkable improvement, with decreased levels of chemical oxygen demand and biological oxygen demand. After the lockdown, spatial variation in nitrate concentration was observed in the upstream region.

Summary: Large-scale soil erosion modeling plays a crucial role in soil and water conservation planning. The lack of spatial data on soil characteristics has been a major obstacle in Brazil for computing the soil erodibility (K-factor). In this study, a high-resolution spatially explicit soil erodibility map was computed using USLE nomograph and EPIC equations, with USLE nomograph providing more precise estimation of the K-factor in Brazil compared to EPIC.

Summary: This research prioritizes the sub-watersheds within the Wyra watershed based on morphometric and hypsometric analyses. SW2 and SW9 have higher priorities according to morphometric analysis, while SW6, SW7, and SW10 have higher priorities based on hypsometric analysis. The most vulnerable sub-watersheds, which should receive more attention for soil and water conservation, are those with the highest priority.

Summary: This study aimed to identify major socio-economic characteristics that have contributed to the occurrence of water erosion events in the Czech Republic. The results revealed that plot size and land tenure are significant predictors of repeated erosion events. To protect agricultural land more effectively against water erosion, recommended updates to agricultural environmental standards.
