Biogeochemical cycles in forests


The research group “Biogeochemical cycles in forests” is a cooperation between this department, the Department of Physical Geography at Stockholm University and CEC at Lund University. We use empirical data together with the dynamic forest ecosystem model ForSAFE for two purposes - to develop process understanding about nutrient and carbon cycling in forests, and to address questions about future effects of climate change, different types of forest management and atmospheric deposition on soil chemistry, runoff water quality and tree growth. The SWETHRO monitoring network, managed by IVL, is an important platform in our work, and we have extensive and very fruitful cooperation with the SWETHRO group at IVL. The research falls within the strategic research area BECC (Biodiversity and Ecosystem services in a Changing Climate). One aim with our research is to provide mainly Swedish stakeholders, e.g. the Energy Agency, the Environmental Protection Agency, the Forest Agency and the Swedish Agency for Marine and Water Management, with decision support.

Teaching


I teach at various courses at this department and at CEC. My main teaching efforts are on two courses at this department - “An introduction to the global environment”, where I am the course coordinator and “Land surface processes and landscape dynamics”, where I am one of the main teachers.

 

Involvement in BECC


Since autumn 2016 I am leading one of the three challenge themes in the strategic research area BECC, the one about Ecosystem Services: “Mainstreaming [consideration of] ecosystem services into land use
decision-making under global change”. The vision of the theme is:

“…to be an internationally visible hub generating innovative transdisciplinary science studying and supporting the generation and use of ecosystem services and providing insights for decision making in a society facing global change.”  

You are very welcome to contact me if you want to discuss ideas related to this theme.
