2. 1. Modelling regional climate-vegetation interactions in Europe : A palaeo perspective

   Author : Gustav Strandberg; Erik Kjellström; Qiong Zhang; Johan Nilsson; Hans Renssen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palaeoclimate; climate model; vegetation; vegetation changes; land-cover; changes; proxy data; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Abstract : Studies in paleoclimate are important because they give us knowledge about how the climate system works and puts the current climate change in necessary perspective. By studying (pre)historic periods we increase our knowledge not just about these periods, but also about the processes that are important for climatic variations and changes. READ MORE

4. 2. Monitoring transport and fate of de-icing salt in the roadside environment : Modelling and field measurements

   Author : Annika Lundmark; Per-Erik Jansson; Bo Olofsson; Ann-Catrine Norrström; Helen K. French; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chloride; De-icing salt; Groundwater; Modelling; Monitoring; Road; Roadside; Soil water; Water in nature and society; Vatten i natur och samhälle;

   Abstract : Roads and traffic are a major non-point source of pollutants and may have severe impacts on surface water, groundwater, soil and vegetation. In cold climates, de-icing salt is one such pollutant that may cause increased chloride concentrations and induce other effects on the environment. READ MORE

5. 3. Environmental Modelling : Learning from Uncertainty

   Author : John M. Juston; Per-Erik Jansson; Jens Christian Refsgaard; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Models; data; error; uncertainty; hydrology; soil carbon; wetlands; phosphorus;

   Abstract : Environmental models are important tools; however uncertainty is pervasive in the modeling process.   Current research has shown that under­standing and representing these uncertainties is critical when decisions are expected to be made from the modeling results. READ MORE

6. 4. DYNAMIC MODELLING OF BIOGEOCHEMICAL PROCESSES IN FOREST ECOSYSTEMS

   Author : Salim Belyazid; Avdelningen för kemiteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Naturvetenskap; marklära; Silviculture; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik; Natural science; Lantbrukshydrologi; Soil Science; agricultural hydrology; Växtekologi; Forest Soil Acidification; Plant ecology; Plant biochemistry; Forest Growth; Vegetation biodiversity; Carbon Sequestration; Nitrogen Leaching; Miljökemi; Dynamic Modelling; Växtbiokemi; Environmental chemistry;

   Abstract : Forests in Sweden are undergoing rapid and considerable changes regarding both management methods and environmental conditions. To understand the effects of these changes and to be able to predict impending changes in forest ecosystems, a holistic understanding of the processes governing the ecosystem is needed. READ MORE

7. 5. Biophysical and Human Controls of Land Productivity under Global Change : Development and Demonstration of Parsimonious Modelling Techniques

   Author : Florian Sallaba; Institutionen för naturgeografi och ekosystemvetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ecosystem Modelling; Meta-modelling; Net Primary Production; Global Change; Model coupling;

   Abstract : Net primary production (NPP) serves as an indicator for plant-based resources such as food, timber and biofuel for human appropriation. It is defined by the annual production of plant matter and is mainly controlled by climate and human activities. Climate change in combination with human activities is altering NPP. READ MORE
