Summary: The study evaluated the impact of long-term grazing exclosure on soil physicochemical and erodibility properties as well as vegetation in the Bozdaghi region of Iran. The results showed significant positive effects on soil properties, particularly an increase in soil organic matter and total nitrogen in the surface layer of the soil.

Summary: This study evaluated the effects of exclosure management on hydrological functions and services in a savanna ecosystem in southwest China. The results showed that exclosures significantly improved soil physical properties, water infiltration, and preferential water flow. The study also found that the restoration and niche differentiation of herb and woody plants in exclosures played important roles in improving water availability and management in savanna systems.

Summary: South Sudan is focusing on developing large hydropower (LHP) to improve access to electricity. However, it takes a long time and is expensive. This study assesses the potential of run-of-river (ROR) small hydropower (SHP) as an alternative. The study identifies 82 potential SHP sites in South Sudan with a total output power of 1651.69 MW and a yearly output energy of 8.68 TWh. Economic analysis and environmental impact assessments are recommended before installation.

Summary: This study evaluates the usability of different indirect ET estimation methods for catchment-scale drought and irrigation planning, revealing discrepancies in the estimation results. It shows that the VIC-3L model may significantly overestimate ET, while the MOD16A2 product provides relatively more accurate estimates.

Summary: The study showed that overgrazing and long-term grazing exclosures have different impacts on the distribution and loss of photosynthesized carbon in the soil-plant system. Grazing-excluded areas had higher allocation of newly assimilated carbon in plants, but lower loss through soil and shoot respiration, while overgrazed areas had higher losses through shoot and soil respiration.

Summary: This study introduces an improved HRU definition method that minimizes the loss of watershed biophysical information without significantly increasing the number of HRUs or lowering user-defined thresholds. The new HRU model better represents land use and soil distribution characteristics and improves the simulation of hydrological and water quality variables compared to the default SWAT model.

Summary: This study examined the runoff and soil loss responses under different land management practices in three climatic regions of the Ethiopian highlands. The results showed significant variations in runoff and soil loss amounts, highlighting the importance of carefully designing and evaluating soil and water conservation measures specific to land use and climatic conditions.

Summary: This study evaluated the effects of exclusion periods using cages on morphological, physiological, and morphogenetic responses of 'Mulato II' hybrid brachiariagrass pastures and how it affected estimates of forage accumulation. Grazing exclusion resulted in greater rates of leaf and stem growth inside the cages, leading to overestimation of forage accumulation. Placement of cages and number of sampling sites are important factors that can affect the accuracy of forage mass estimates.

Summary: Identifying key processes and sources of water and nutrient losses is crucial in watershed management. This study used the SWAT model to simulate water and nutrient balance in an agricultural watershed in the U.S. Corn Belt. The results showed that the corn-soybean rotation system was the main contributor to nitrogen and phosphorus inputs and losses, and the non-growing season was identified as the critical period for water and nutrient losses.

Summary: The present study aims to simulate the effects of land-use and topographical changes due to coal mining on surface runoff in the Jamunia basin of Jharkhand, India. The results revealed a significant increase in surface runoff during the simulation period. This study indicates that unplanned mining activities can reduce the water holding capacity of downstream reservoirs and increase the runoff.

Summary: This study compared three gridded precipitation datasets and evaluated their suitability using conventional gauge observations. The results showed that PRISM data performed the best in quantifying rainfall volume, and the models driven by PRISM and TRMM also had better results compared to the CFSR and gauge-driven models.
