6. Skog, makt och människor. En miljöhistoria om svensk skog 1800-1875
Sammanfattning : The aim of this dissertation is to investigate how and why silviculture was introduced in Sweden in the nineteenth century and the consequences this introduction had during the same period. The term silviculture refers to the systematic cultivation of high forest, a method that spread from Germany at the end of the eighteenth century. LÄS MER
7. Modelling Chemical Weathering in Different Scales
Sammanfattning : Chemical weathering is one of the most important processes supporting life on Earth. Chemical weathering continuously contributes macronutrients and micronutrients to the soil solution. These recycling, essential elements are used as building blocks for all organic living matter.

8. Modeling nutrient cycling and sustainable forest growth in a changing world
Sammanfattning : It took 70-80 years to realize the width of the impact of industrialization on the forest ecosystems since a forest ecosystem is a "slow system" as seen from a human perspective. An anticipated future climate change and increasing carbon dioxide and ozone levels will change the conditions even more with time and the widely used statistical forest growth models will not be applicable anymore.

9. Regional Nutrient Budgets in Forest Soils in a Policy Perspective
Sammanfattning : Sweden's forests are one of its most important natural resources, as well as being important from ecological and social perspectives. Nutrient sustainability is essential to maintain the production capacity and reduce the effects of acidification and eutrophication. LÄS MER
10. Nutrient imbalance in Norway spruce
Sammanfattning : The studies presented in my thesis indicate that growing Norway spruce in monoculture does not constitute sustainable forest management in a high N and S deposition environment, such as in southern Sweden. The combination of N-induced high growth rates and leaching due to soil acidification causes soil reserves of nutrients to decrease. LÄS MER
