Nordic stakeholder conference 9 june 2022: Registration is open!

In this conference we explore how our freshwaters will be affected by the “Green Shift”, or bioeconomy (the transformation from fossil fuel to bioeconomy, with its demand on biomass). BIOWATER has studied how land use and therefore water quality may change as a result of land use and climate change. See the programme and register for Biowater’s Nordic stakeholder conference

An in-depth look at Iron in boreal streams

In boreal catchments, iron has a key role in biogeochemical and ecological contexts, and at the same time has many harmful impacts on aquatic organisms and ecosystems. Recent studies indicate that iron concentrations are increasing in boreal freshwaters, with the potential negative effects this can have on water ecology. Finnish researchers have now explored the many aspects of iron in

We congratulate Dr. Hannah Wenng, who received her PhD after a successful defence on 18 November 2021. The title of Hannah’s thesis is “Impacts of Climate and Agricultural Management on Hydrology and Water Quality. A Headwater Catchment Scale Approach.” In her work, Hannah has studied the connections between agricultural practices, climate, and freshwater environment. She has approached this topic from

Ditch maintenance in drained peatland forestry – good or bad?

Cleaning of ditches to maintain an adequate water table is a common practice in peatland forestry. Ditch maintenance promotes forest growth by keeping the water table at favourable level but as a negative side effect it increases nutrient and sediment loads to waterways. In Finland, scientists have examined the trade-off between increased harvest revenues and declined water quality due to

Excess nitrogen from agriculture may reduce variation of diatom species in streams

Researchers at the University of Oulu and the Finnish Environment Institute have addressed the question on how diatoms in rivers respond to different nutrient conditions. Interestingly, they found that high concentrations of dissolved inorganic nitrogen seem to reduce the species variability, probably because sensitive taxa disappear, while certain tolerant taxa can survive. Phosphorus is traditionally believed to be the limiting

Nationwide study: Forests along rivers improve ecological condition

There is increasing evidence that forested riparian corridors improve the ecological status of freshwaters, but this Finnish study takes one step further and looks at the effect on a national scale. The scientists used data from more than 900 river water bodies in Finland. They found that the ecology of small to medium sized rivers in an agricultural landscape benefitted
