Abstract Diffusive losses of nitrogen and phosphorus from agricultural areas have detrimental effects on freshwater marine ecosystems. Mitigation measures treating drainage water before it enters streams hold a high potential for reducing areas. To achieve better understanding the opportunities challenges characterising current new mitigation in oceanic continental climates, we reviewed nitrate total removal efficiency of: (i) free surface constructed wetlands, (ii) denitrifying bioreactors, (iii) controlled drainage, (iv) saturated buffer zones (v) integrated zones. Our data analysis showed that load was substantially reduced by all five measures, while they mainly acted as sinks phosphorus, but occasionally, also sources. The various factors influencing performance, such design, runoff characteristics hydrology, differed studies, resulting large variation reported efficiencies.

In this opinion paper, we assess how soils associated land management can help achieve goal, considering at two scales: local soil health healthy landscapes. merging of these viewpoints shows the interlinked importance scales.

Various national policies guide forest use, but often with competing policy objectives leading to divergent management paradigms. Incoherent may negatively impact the sustainable provision of ecosystem services (FES), and multifunctionality. There is uncertainty among policymakers about impacts on real world. We translated documents Finland into scenarios including quantitative demands for FES, representing: strategy (NFS), biodiversity (BDS), bioeconomy (BES). simulated a Finland-wide systematic sample stands alternative regimes climate change. Finally, we used multi-objective optimization identify combination matching best each scenario analysed their long-term effects FES.

Freshwaters of the boreal and temperate regions have experienced increased browning during last decades. Browning, or brownification, is mostly driven by organic carbon (OC) iron concentrations. It can cause detrimental changes in aquatic ecosystems through effects on chemistry, physics ecology. Additionally, impact greenhouse gas emissions, increase costs drinking water treatment weaken recreational value bodies. All these impacts call for means to mitigate excess export humic matter ecosystems. Browning has often been associated with decreased atmospheric sulphur deposition climate change-induced alterations temperature, vegetation hydrological regime catchments. Lately, it attributed land use, especially drainage peatlands forestry purposes afforestation. In this review, we evaluate peatland operations OC leaching assess possible mitigation measures. We reveal that traditional, even-aged forest management clear felling, site preparation ditch cleaning creates hot spots moments carbon-rich runoff due fluctuations hydrology, peat decomposition exposure. Simultaneously, most current protection measures are either ineffective ambiguous retaining OC, a dissolved form. Hence, practices prevent future reduce connectivity essential negative quality impacts. conclude systemic change would be needed formation loading leaching.

Streams draining agricultural areas fine-grained soils had better than forested more coarse-grained soils. However, also revealed considerable differences methodological approaches, including analytical methods determine sampling strategies, quality control procedures, measuring principles. Relatively few national countries involved included optical sensors, which partly explain this lack harmonisation. Given risk future fluxes, increased harmonisation highly recommended, so evaluated intercalibrated across comparable geographical regions.
