Lateral transfers of carbon play a non-negligible role in the carbon budget of terrestrial ecosystems. These transfers can be related to the removal of biomass through grazing or through harvest of wood, grass and crops, but also to the leaching, erosion and redeposition of soil organic carbon. Lateral transfers of carbon through trade of biological products or through transport with the river load become important at regional to global scales.
Quantification of these lateral carbon transfers and their impact on the land carbon budget remains challenging, but is urgently required to better constrain the land carbon budget and to better understand its response to historical, present, and future perturbations.
This workshop brings together leading researchers working on these lateral carbon transfers at local to global scales, including experimentalists as well as modelers.
The aim of this workshop is to give an overview of ongoing research on this topic and to encourage the interdisciplinary exchange among the presenters but also with the audience. (Registration form below.)
