    Impacts on water quality in the peatland dominated catchment due to foreseen changes in Nordic Bioeconomy Pathways

    The Nordic Bioeconomy Pathways (NBPs), conceptualized subsets of Shared Socioeconomic Pathways varying from environmentally friendly to open-market competition scenarios, can lead to plausible stressors in fut...

    A new evolutionary time series model for streamflow forecasting in boreal lake-river systems

    Genetic programming (GP) is an evolutionary regression method that has received considerable interest to model hydro-environmental phenomena recently. Considering the sparseness of hydro-meteorological station...

    Arctic sea-ice loss fuels extreme European snowfall

    The loss of Arctic sea-ice has been implicated with severe cold and snowy mid-latitude winters. However, the mechanisms and a direct link remain elusive due to limited observational evidence. Here we present a...

    A synthesis of the impacts of ditch network maintenance on the quantity and quality of runoff from drained boreal peatland forests

    Drained peatlands are an important source of forest biomass in boreal regions and ditch network maintenance (DNM) operations may be needed to restore the drainage functions of ditches. By reviewing the availab...

    Increasing and Decreasing Nitrogen and Phosphorus Trends in Runoff from Drained Peatland Forests—Is There a Legacy Effect of Drainage or Not?

    A recent study on nitrogen (N) and phosphorus (P) exports from drained peatland forests reported increasing concentrations over long time since their initial drainage. Concurrently, some other studies have sug...

    Assessment of uncertainty in constructed wetland treatment performance and load estimation methods

    Constructed wetlands (CWs) are commonly established to reduce pollution load from different sources. In environmental permits, the load remaining after CW purification is typically estimated through concentrat...
