The Congo Biogeochemical Observatory is an international consortium of researchers who study biogeochemical cycles (the pathways by which a key elements like carbon, nitrogen, and phosphorus move through the biotic and the abiotic compartments of Earth) in tropical Africa with focus on the Congo Basin. The Congo comprises the second largest swathe of tropical forest on Earth and faces mounting impacts from forest loss driven by shifting agriculture in concert with rapid human population growth. Given these accelerating impacts, we believe it is critical to study the biogeochemistry, ecology, and hydrology of this globally relevant yet largely understudied region.

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 forest types were measured; which could be due to the direct conversion to N2.
