I’m working as post-doc with Charly Favier on the CoForChange Project. I’m studying the influence of climate change and human activities on the forest structure in the Congo Basin.

We’re using the LPJ-GUESS model and adapting the current plant functional types to better represent the forest structure found in the study area. The CoForChange study area is a tropical moist forest vegetated by a mix of evergreen and deciduous trees. Within the project, field data on vegetation composition and soil characteristics have been collected and access to surveys from logging companies provide additional information that we can use to refine LPJ-GUESS.

The aim of my work is to create policy-relevant projections of the impact of climate change under different logging scenarios for the Congo Basin forest.
