Summary: This study investigated the impact of landscape composition and configuration on legacy phosphorus releases in headwater catchments. It found that the relative contribution of landscape patterns to legacy phosphorus releases was greater than that of soil P and terrain factors. Specific land use patches, such as woodlands and ponds, were identified as potentially significant in alleviating legacy phosphorus releases.

Summary: This study evaluated the changes in hydrological and sediment connectivity in the Santa Cruz catchment in Mexico over a period of 42 years and projected these changes under a climate change scenario. The results showed that changes in land use/cover and expected climate change would modify hydrological and sediment connectivity. Under future conditions, there is likely to be an increase in runoff and sediment transport, which will impact soil erosion and vulnerability to flooding.

Summary: This study investigated phosphorus (P) delivery and transport during flood events in an agroforestry catchment. Sediments were collected from five locations in the catchment over a period of 5 years, and properties such as particle size, soil organic matter, low frequency magnetic susceptibility, and P and Ti concentrations were analyzed. The results showed that the sediment exhibited enrichment in P compared to the sediment sources, with higher P concentrations associated with clay and organic matter-rich sediment. The highest P losses were recorded at the catchment outlet, where cropland was dominant. The differences in monitoring campaigns were attributed to variations in precipitation patterns, which influenced the hydrological response.

Summary: Managing phosphorus is a global priority for environmental water quality. A study in Western Australia's Fitzgerald River catchment found that dissolved phosphorus transport was dominant, with physical filtering methods like riparian vegetation proving ineffective in restricting phosphorus transport into streams. Evidence-based fertiliser advice could help reduce dissolved reactive phosphorus losses without yield loss.

Summary: With the widespread use of nitrogen fertilizers in the agricultural sector, there is an increasing pollution of nitrogen in the karst area of southwest China. This study used isotopic techniques to investigate the changes and sources of nitrates during rainfall in different land uses in a typical karst catchment. The results showed that agricultural activities caused water quality deterioration, while heavy rainfall during the wet season played a positive role in promoting it. Nitrate isotopic compositions revealed that dryland and paddy field were mainly affected by nitrification, and source analysis showed that chemical fertilizers and manure were dominant in dryland and paddy field, while precipitation and soil organic nitrogen were major sources in abandoned land, forest, and shrub.

Summary: This paper focuses on the impact of changes in land use in the lowland catchment on water resources in the Zagozdzonka river in central Poland over the past 50 years. Results indicate that climatic factors and socio-economic changes in agriculture play a significant role in reducing water resources, while the positive impact of forest areas in the catchment area depends on water demand. The interactions between forest ecosystems and water retention are strong and may deepen water deficit in the catchment area during dry periods.

Summary: This study examines the temporal evolution of nitrate and phosphorus loads and concentrations in a rural catchment in Galicia over 14 hydrological years. While nutrient concentrations are relatively low due to the rural nature of the catchment and low-intensity agriculture, they consistently exceed catchment nutrient reference levels. Water flow is the main driver of nutrient transfer, but there are no consistent trends in nutrient fluxes. Nitrate appears to be decreasing, mainly in autumn and spring, while phosphorus shows an increase in winter due to higher flow and sediment transfer.

Summary: High-resolution climate data is crucial for predicting regional climate and water environment changes. In this study, a two-step downscaling method was developed to enhance the spatial resolution of GCM data and improve the accuracy for small basins. The method combined medium-resolution climate data with high-resolution topographic data to capture spatial and temporal details. The downscaled climate data were then used to simulate the impacts of climate change on hydrology and water quality in a small basin. The results demonstrated the effectiveness of the downscaling method for spatially differentiated simulations.

Summary: Precipitation over the Tibetan Plateau is influenced by systems such as the Asian monsoons, the westerlies, and local circulations. The Indian monsoon, the westerlies, and local circulations are the main systems affecting precipitation over the entire Tibetan Plateau. The East Asian summer monsoon primarily affects the eastern Tibetan Plateau. The Indian monsoon has the greatest influence on precipitation in the southern and central grid cells, while the westerlies have the greatest influence on precipitation in the northern and western grid cells. Local circulations have the strongest influence on the central and eastern grid cells.
