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.
We are all Peepoople
One billion of the world’s population does not have a toilet. A few more billions use primitive dry toilets and risk infections. This is the starting point for Peepoo, a bag which turns the notion of what a toilet is, upside down.
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.
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.
