The general objectives of the BIOSERF project were to explore the evolution of a socio-ecological system, with a focus on ecosystem services and to assess their sustainability in an area of evergreen tropical forest under increasing human pressure and climate change. For this purpose, we aimed at adapting two dynamic spatial models, one dynamic vegetation model (CARAIB) simulating various aspect of vegetation development and an agent-based model (ABM) simulating land-use by people. The study area was a stretch of forest and savannah in the Congo Basin also known as the WWF Lake Tumba landscape in the Democratic Republic of Congo.
