Abstract A generic savanna model has been developed, which offers the framework to describe and simulate the vegetation dynamics of different Namibian savanna systems along the BIOTA North-South-transect. The model consists of two coupled submodels, a soil-water model and a vegetation model. It has been parameterised for the BIOTA observatory Otjiamongombe West 44/ Erichsfelde (thornbush savanna). The model allows to analyse the effects of changes in rainfall amount and variability due to climate change and of different land use strategies on the vegetation as well as feedback mechanisms between vegetation and soil moisture.
