A new article published by our observatory in Nature Communications shows extremely high methane emissions in flooded tropical forests of the Congo Basin whereas relatively low nitrous oxide emissions from all studied forests types were measured; which could be due to the direct conversion to N2.

A new CBO-led study that found that high phosphorus in African tropical forests is sourced from fires and scales with canopy complexity. These results highlight how older and more complex forests have higher surface areas for dry deposition to settle onto and thus trap more phosphorus.

Contrasting nitrogen fluxes in African tropical forests of the Congo Basin: New paper in Ecological Monographs

The paper published in Ecological Monographs focused on three main question:

"(1) How does the abiotic environment affect N cycling in tropical forests by comparing montane and lowland forest?

 (2) How does forest type within each geographical location affect the N cycle, i.e., what is the variability that can be expected from a change in biotic forest composition?

 (3) How does the N cycle of tropical forests in the Congo basin compare to the better‐documented South American and Southeast Asian tropical forests?"

Sustainability in the heart of darkness

"The Democratic Republic of Congo (DRC) is mostly known for its social, economic, and political instability. Does it make sense then for me to focus my research on sustainable agriculture and the role of the Congo River Basin in the global carbon cycle?" Johan Six (Professor of Sustainable Agroecosystems, ETH Zurich) explains why it is important to have research projects in the DRC.
