Focus ecosystem Savannas
Savannas are the most widespread ecosystems in Africa. They house globally significant reservoirs of biodiversity and provide essential ecosystem services for their inhabitants.

African Savannas are severely threatened by population growth, land-use change and climate change and the Global Biodiversity Outlook 3 identified African savannas as one of 9 global biodiversity tipping points. Anticipating how savannas will respond to global changes is therefore a key challenge for developing sustainable mitigation and adaptation strategies for savannas.
In the first phase of BiK-F scientists studied past and potential trajectories of change in savannas using a combination of empirical and modelling work that spanned paleo-ecological and contemporary time scales. Highlights include studies of the rise of C4 ecosystems in the Miocene, genetic analyses of grass and ungulate evolution, projections of biome and species shifts, and the valuation of ecosystem services. In the workshop we will discuss instruments for further integrating existing research and developing new and innovative research themes (e.g. joint workshops, journal special issue, savanna data portal).
