Output from these production system models are incorporated into simulations of entire rangelands over many decades using the frame-based modelling paradigm. Future projects Models developed for the following projects could form the basis of an MSc or PhD thesis. These are multi-disciplinary projects and honours graduates in any branch of science or agriculture will be considered. Some knowledge of computer programming would be helpful.
NRF funding is available.
In collaboration with the National Botanical Institute and the Department of Animal Science at the University of Fort Hare we are developing a series of computer simulation models of livestock production and the ecosystem for communal rangelands in Namaqualand. You will develop a computer simulation model of diet selection and nutrient utilization by sheep and goats grazing succulent Karoo. This is a multidisciplinary project that will involve both some experimental work in the field and computer modelling. Recent results from the rangeland modelling project have indicated the important influence of goats on the stability and sustainability of rangeland systems. Consequently rangeland models depend on accurate representation of the performance of goats and their impact on the vegetation and on the productivity of the whole system.
