Abstract Climate and land use changes are most important drivers for ecosystem dynamics in West Africa where various types of forest and savanna dominate and cash crop plantations keep on expanding. These vegetation types have been studied in detail with respect to their quantitative and qualitative composition, soil, relief, climate, fire, agronomic, land use, social, economic and cultural parameters in order to determine and differentiate natural and anthropogenic key factors causing large-scale dynamics of these systems. Based on these analyses integrative modelling approaches have been set up in order to test the effects of varying land use on the structure and diversity of the ecosystem but also on socioeconomic factors. The synthesis of these analyses provides recommendations for future options of a sustainable management and utilisation of natural resources. Further research will focus on generating future scenarios on options of use and conservation of natural resources in combination with the sub-continental modelling of BIOTA for the geographically vast and climatically sensitive Guineo-Sudanian transition zone in West Africa.
