Heureka – balancing forest objectives
Swedish forest owners can now use their computers to see how their management actions affect forest areas. A single tool can be used to combine economics, ecology and social values – a globally unique concept.
Mapping the ultrastructure of wood
The structure of wood cells determines how strong and moisture-resistant the wood is, and also how easily it is attacked by various wood-degrading fungi. New knowledge about wood fibres is of benefit to the timber, pulp and...
Planning cities for playfulness
Increasing numbers of the world's children grow up in cities. Outdoor urban environments are therefore of growing importance for children's day-to-day mobility.
Environmental toxins know no boundaries
After use on crops, pesticides have long moved freely between countries, carried by wind and water. This leakage is a major environmental problem. Attempts are being made to solve it by way of international cooperation. Jenny...
Getting a grip on greenhouse gases
The exchange of greenhouse gases between the earth's surface in Europe and the atmosphere has hitherto been monitored in separate projects, but a European network of monitoring stations is starting to take shape.
The return of the wolf
Having been almost completely absent for more than 100 years, the wolf is now rapidly recolonising central Sweden. Its return has met with strong feelings in many quarters.
Putting children on the map
A number of Swedish municipalities are using a method called “Children's maps in GIS” to find out how children feel about and use their outdoor environment.
Restoring forests little by little
"Caring for the environment is a way of restoring our forests while we use them," explains Lena Gustafsson, Professor of Nature Conservation Biology.
Growing algae for fuel and feed
Algae grown in sewage and flue gases can be transformed to biogas, bioethanol, biodiesel, fertiliser or fish and animal feed.
Adapted forest fertilisation: more good than harm?
In Sweden, forest land is fertilised with commercial fertilisers to increase the growth of forest trees. Only a small portion of Sweden’s forested land is fertilized this way and studies so far show that there is little effect...
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...
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...
Planning for both timber and biodiversity
With the help of the Heureka system (a software tool), SLU researchers have asked the question how the forest should be managed to provide both high profit and good habitats for various species.
Following Global Forest Trends
Karin Beland Lindahl, researcher at SLU, studies international forest trends and how they may affect future forest management in Sweden.
Community elders showed the effects of forestry
Solomon Gebreyohannis and Professor Kevin Bishop have been studying the relation of forest cover and river flow in the Koga watershed, a headwater of the Blue Nile in Ethiopia.
Mapping Swedish Fells
At SLU in Umeå, researchers are developing new techniques for automated mapping of land cover.
Traces of Chernobyl remain in reindeer
Several of the 51 reindeer herding districts in Sweden still have to adapt management to reduce the caesium content in reindeer. In total, this costs the Swedish society seven million Swedish crowns per year.
Follows Nature's Calendar
The Swedish University of Agricultural Sciences (SLU) has collected 350 000 phenological observations made during the period 1873-1918 from across Sweden in a unique data base. These historical observations combined with...
What natural environment do we want?
SLU researchers have played an important role in Sweden’s 150 year long history of environmental acidification, for instance the acidification process was first shown by soil researcher Svante Odén in the 1960s. Reduced sulphur...
Later coastal fishing favours wild salmon
Robust salmon stocks in the Baltic Sea are possible with the right knowledge and fishing methods, as suggested by Professor Hans Lundqvist and Associate Professor Kjell Leonardsson at the Department of Wildlife, Fish and...
Mink warn of chemicals in the environment
SLU researchers have developed a new environmental monitoring system in which methods have been developed to reveal reproductive impairment in wild mink.
Landscape characterisation methods
SLU researchers are developing methods of describing landscape character, i.e. the patterns and structures that distinguish one landscape from another.
MOTH finds less common habitats
Every sixth years, Sweden is to report on the conservation status of the habitat types specified in the EU Habitats Directive*.
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...
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.
Odour and Noise Causes of Conflict
Railways, traffic, factories and farms are just a few examples of sources of discomfort and conflict, but exactly how common are problems of odour and noise in modern society?
The Neighbourhood through the Eyes of your Child
What do children think about the outdoor environment in their neighbourhood? Researchers at the Swedish University of Agricultural Sciences (SLU) have developed a method using a Geographic Information System (GIS).
High Risk of Vole Fever in Northern Sweden
We are facing an outbreak of vole fever during winter, according to the annual forecast made by scientists at the Swedish University of Agricultural Sciences (SLU). This year’s high number of bank voles will spread the illness...
Domestic Cat Reveals Hazardous Substances at Home
The domestic cat and its human owner share the same environment to a large extent. The cat can therefore serve as a model for the exposure and uptake of hazardous substances at home, especially applicable to small childr...
Mink as a Sentinel Species
Researchers at the Swedish University of Agricultural Sciences (SLU) have developed an environmental monitoring system using the Swedish wild mink as a sentinel species.
Working towards a Non-Toxic World
Leif Norrgren is Professor at SLU with a strong international commitment to environmental issues. He collaborates with people all over the world in projects concerning toxic substances and pathogens connected to water.
Fewer species with rising crop yields
While crop yields from European agriculture have doubled, biodiversity has declined. Half of all plant species and one-third of ground beetles and birds have disappeared from the agricultural landscape.
Diatoms reflect lake quality
Stationary diatoms reveal whether a river or stream is eutrophied, acidified or affected by organic pollutants. Researchers at SLU in Uppsala are now determining whether the method using diatoms as an indicator in watercourses...
Urban cows and wind mills arouse strong feelings
Farm animals grazing in the park and new wind farms change the landscape and sometimes spark conflicts. Dr Ingrid Sarlöv Herlin, landscape researcher at SLU in Alnarp, is examining ways of reconciling stakeholder inter...
Grass can heat houses in the north
The perennial plant reed canary grass is an alternative energy crop in northern Sweden, where Salix struggles to survive in winter.
Monitoring methane from cows
Methane (CH4) is a greenhouse gas formed when cows and other ruminants digest their food. 95 per cent of the gas is released when the cow belches; the rest is emitted anally.
Browner water with less acidification
As sulphur deposition decreases, our lakes and watercourses are becoming ever browner, an effect caused by humus from surrounding land.
