Summary: Climate change and riparian management are significant drivers of hydrological change, impacting nutrient fluxes in lowland streams. Long-term assessment in a mixed land use catchment in northern Germany revealed how climatic variability influences hydrological dynamics, with discharge and groundwater levels closely linked to changes in temperature and rainfall. The study also highlighted the role of beaver dams in moderating flow regimes and facilitating groundwater recharge, as well as the complex dynamics of nutrient concentrations and fluxes in stream water systems.

Summary: This study examines the impacts of climate change on streamflow and water quality in the subtropical Logan-Albert catchment in Australia. The results show that climate warming may lead to decreased streamflow and contaminant loads, with the largest decreases predicted during the dry season. This could result in reduced flushing and increased importance of point source loads in urbanizing catchments.

Summary: Seasonal physicochemical parameters at different stations along the Negro River Estuary in Argentina were studied, revealing higher total phosphorus concentration in warmer months compared to previous data, with orthophosphate values also high and fluctuating independently of total phosphorus. Turbidity, water temperature, pH, and conductivity did not seem to play a key role in phosphorus variations. An unexplained high total phosphorus spike in spring samples suggests the need for further research in the area.

Summary: Rainfall participates in the soil acidification process through hydric erosion and leaching processes. Sediment detachment and transport by runoff water lead to the loss of divalent cations, while leaching processes are responsible for the loss of monovalent ions. Soils with a higher position and slope show more significant losses of sediment, divalent cations, OM, NK, and P Bray. On the other hand, CoAoMo has the lowest sediment, OM, and NK losses due to its high sodium concentration, but it also presents the highest TRP into runoff waters. Sediments are enriched in fine materials, OM, and NK.

Summary: To meet the challenge of producing large amounts of healthful animal and plant foods while maintaining ecosystem services and conserving essential nutrients, increased research on-farm and at the watershed scale is necessary. Collaboration with diverse interdisciplinary teams is crucial to develop innovative solutions and utilize a combination of techniques linked to agroecology and industrial ecology. Recycling nutrients within food production systems and producing animal and plant foods more efficiently will cut costs and increase desirable outputs.

Summary: This study aimed to improve the prediction of nutrient fluxes from agricultural streams in southern Ontario by improving the representation of water source contributions to streamflow in generalized additive models. By calibrating a recursive digital filter using stable isotopes of oxygen in water, the accuracy of baseflow estimates was significantly improved. The revised model provided a more accurate prediction of nutrient losses from the agricultural watersheds.

Summary: The study found a connection between climate oscillation and NPS pollution, indicating that the increasing frequency of warm ENSO events would enhance the risk of nutrient export to rivers in Southeast China. Therefore, more attention should be paid to large-scale climate oscillation in the prediction of agricultural nutrient pollution and management of water quality in agricultural watersheds.

Summary: This study evaluated the impacts of wastewater treatment plants with different classifications of tertiary treatment on nutrient dynamics in the River Wensum catchment, UK. The majority of nutrients were found in bio-available forms, with phosphorus mainly of agricultural origin. Phosphorus-stripping facilities did not reduce total P concentrations downstream of WWTPs, indicating their insufficiency in overcoming population pressures and ensuring river reaches good hydrochemical status.

Summary: Lentic water bodies, such as lakes, reservoirs, and wetlands, play a crucial role in retaining excess nutrients from runoff and protecting downstream water bodies from eutrophication. However, global studies on water body nutrient retention are biased towards North America and Europe, overlooking valuable research published in Chinese journals. This study synthesized data from 417 water bodies in China and found that wetlands retain more nutrients compared to lakes and reservoirs. The study also revealed the influence of water body size and regional temperature variations on nutrient retention.

Summary: This study quantitatively assessed anthropogenic phosphorus (P) input in the Jianghan Plain from 1990 to 2019. The results showed that P fertilizer input and livestock density were the main drivers of P input change. Only a small portion of P input was exported into rivers, with a large amount accumulating in the terrestrial system. Measures to improve fertilizer use efficiency and manure management are necessary to control P pollution.

Summary: This study conducted a living laboratory research in the prairie pothole landscape in Alberta, Canada, to demonstrate the use of new scientific tools and policy instruments for wetland restoration. Despite the strength in science and policy, the implementation of the restoration program was stalled due to various barriers, limiting the participation of landowners and resulting in a small number of wetlands being restored. The study highlights the importance of understanding the practice realm and engaging practitioners in wetland restoration activities.

Summary: Global changes have led to decreases in inorganic nitrogen concentrations and increases in colored dissolved organic carbon concentrations, while reducing the dissolved inorganic nitrogen to total phosphorus ratios in northern lakes. These changes have various effects on phytoplankton and zooplankton biomass and the N:P recycling ratio of zooplankton. A study done in Swedish headwater lakes found that lower nitrogen deposition coincided with lower phytoplankton biomass and higher zooplankton biomass. The composition of zooplankton community also differed between northern and southern regions, with different dominant species. The study suggests that declining nitrogen deposition and increasing lake browning will reduce phytoplankton biomass but enhance seston mineral quality and probably also zooplankton biomass and their recycling efficiency of phosphorus relative to nitrogen.

Summary: The effects of lake browning on trophic functioning of planktonic food webs are not fully understood. Browning increased phytoplankton biomass and concentrations of EPA and DHA in lakes, while the seston n-3/n-6 ratio was lower in temperate lakes due to differences in phytoplankton community composition. Lake browning resulted in increased reliance of zooplankton on heterotrophic microbial pathways, but the responses were highly specific to taxa and regions.

Summary: This paper reviews the literature on the impact of biophysical variables and management practices on forest water-use efficiency. It was found that water-use efficiency varies greatly with forest type, species, age, environmental conditions, and forest management practices. Climatic stresses often have negative effects on forest instantaneous water-use efficiency, and forest thinning can effectively improve water-use efficiency. These findings have important implications for managing the tradeoffs between carbon sequestration and water yield of forests.

Summary: In recent years, unexplained declines in lake TP concentrations have been observed in northern latitudes (> 42 degrees N latitude). Data from 389 lakes in Fennoscandia and eastern North America were analyzed to investigate the effects of climate on lake TP concentrations. Synchrony in year-to-year variability was found within and among different geographic regions, indicating climatic influences. Winter temperature was identified as the most important factor controlling annual TP, followed by summer precipitation.

Summary: Wetlandscapes in the Canadian Prairies are vulnerable to sediment infilling due to land conversion and upland agricultural activities. This study examines the effects of agricultural activities on soil loss and sedimentation rates within agricultural landscapes. Findings reveal that erosion occurs near the top of the catchment toposequences, while deposition occurs within the wetland ecosystem. These transfers from cultivated fields into wetlands highlight the need for soil erosion control practices in order to achieve sustainable management of agricultural landscapes.
