I have been working in research projects in forest management both in Sweden and abroad. The latest project I have been working with is a forest landscape restoration / afforestation project in Northeastern China in Liaoning province. The purpose of the project is to slow down wind borne sand from the Gobi desert, soil erosion control, increase biodiversity, improve water quality and capture CO2 to address global warming.
The teaching I have done has been mainly in silviculture and agroforestry. For many years I have been a course leader in a course in “International Silviculture”
My focus today is doing work on forest landscape restoration and work on an Ecosystem Management Decision Support System that could be used for decision making in forest restoration.
