| Abstract |
Land use practices have led to substantial changes of savanna landscapes worldwide. In particular, heavy livestock farming disturbed the complex dynamics of bush-grass coexistence and modified savanna vegetation in two major directions: shrub encroachment and loss of vegetation (bare patches). Both forms of savanna degradation may result in serious losses of biodiversity and economic productivity. We here present BIOTA results of ecological and bioeconomic studies (field and modelling) from local to landscape scales. They aim to analyse the effects of land use scenarios on vegetation, as well as the resulting effects on the dynamics of populations and genes, and on the diversity of species. The results of our studies enable us to provide (i) scientific support for the conservation of savanna biodiversity and the development of sustainable management strategies (ii) management and educational tools using computer simulation models. Based on this overview of current knowledge and understanding we will evaluate future needs and identify necessary steps to further improve our ability to develop land use strategies, which are economically and ecologically sustainable.
