Knowledge Bank: Eutrophication

Clever fishing part of the solution

Eutrophication of the Baltic Sea is a growing problem. The emission of nutrients to the sea has to be reduced, but better management of fisheries is also required. To implement ecosystem-based management in the future, researchers at SLU are trying to understand the role of fish in the food chain. (2012-03-07)

Robust computer model for load calculations

The "Fyris" model is a calculation model capable of mapping transport and source distribution of nitrogen and phosphorus from a catchment to the sea. (2011-08-19)

Arable land holds phosphorus from the past

Traces of how we historically fertilised agricultural land are still there today, partly as stored phosphorus in the cultivated soil. (2011-07-13)

SLU in Uppsala now has an accredited laboratory capable of analysing diatoms from watercourses. (2011-07-06)

Occurrence of Algae on Spruce Follows Nitrogen Deposition

The amount of algae found on Norway spruce needles in Sweden is a good indicator of the atmospheric deposition of nitrogen. High nitrogen deposition generates high algae growth and low nitrogen deposition generates low algae growth. (2011-03-21)

Value of Ecosystem Services

How high is an ecosystem’s recreational value? What is the value of carbon uptake by forests according to carbon permits under the EU emissions trading scheme? Ing-Marie Gren, professor at SLU, has done the calculations. (2011-03-10)
