Several researchers from GEO (or with ties to) have been attended the first Research & Innovation week from the South Africa-Sweden University Forum (SASUF) held in Pretoria and other parts of South Africa.

Dr. Tobias Rütting (left) presented on Soil nutrients and Climate change; Prof. Hans Linderholm (centre) chair of Theme 1 ”Climate change, natural resources and sustainability” and Dr. Staffan Rosell (right; former PhD at GEO) talked about Rural Livelihood challenges in Ethiopia.


Field visit at Kahuzi Biega NP

we visited a the pristine montane tropical forests in the Kahuzi Biega National Park (DRC), another TropSOC sampling site. Last year two GEO students did their thesis work in this forest (Gross nitrogen turnover rates in Central African tropical montane forest soils through in situ 15N-labelling experiments). Today though we were here mainly for our cousins…

TropSOC meeting in DRC

This week the start-up meeting of TropSOC is held in Bukavu (DRC), which brings together researchers from 3 continents from different disciplines. From GEO, biogeochemist Tobias Rütting is attending.


Excursions are conducted in the South Kivu region and today a visit at the IITA station Kalambo (including soil laboratory) and to experimental farms was made.

Measuring GHG emissions from soil and trees

PhD students learning about different methodologies to measure greenhouse gas (GHG) emissions. Research Engineer Per Weslien demonstrates a laser instrument for measuring nitrous oxide;  Dr. Mari Pihlatie demonstrates that even trees emit GHGs; visiting the Micro-meteorological equipment at Mycklemossen; Prof. Janne Rinne uses the Automated SkyLine2D system to measure 13C isotope in methane.

Greenhouse gas PhD course

This week we are having the PhD course ”Greenhouse gases – biogeochemistry and measurement techniques in ecosystems and landscapes” at the SITES infrastructure Skogaryd Research Catchment, organized bu the Biogeochemistry Group.  PhD students from Sweden and abroad learn about eddy covariance, chamber techniques, stable isotopes and much more.

Computer exercise at ”Hemmet”, hands-on experience with eddy covariance data and footprint modelling.

The course is part of the ClimBEco Graduate School.

Field work in Congo


Recent research expedition to the Central Congo Basin, near Kisangani (DR Congo), together with a PhD student and two MSc students from Ghent University (Belgium). We are interested in how much carbon tropical forests in the Congo basin store and in the soil nutrient cycling, which is important for forest productivity.

Planing the experiment in a local bar; our hut at the Yoko Research Forest; teaching the local kids how to play frisbee; group photo with our local helpers, without the research would not be possible to conduct; weather station at Yangambi (run by INERA), the longest climate data in Central Africa; enjoying the sunset over the Congo river during dinner ob the terrace at Yangambi
