Working Title of Doctoral Thesis
Combined effects of drought and grazing on ecosystem services of semi-arid rangelands in Limpopo, South Africa
Livestock farming in the Limpopo Region of South Africa takes place in arid and semi-arid rangelands that are characterised by low and erratic rainfall and regular droughts. Intensive herbivore grazing exerts extra pressure on the ecosystem, which may lead to rangeland degradation. Besides, climate change models predict rainfall, as well as increasing frequency of more extreme drought events in this region. In my PhD study (part of the subproject “Livelihoods and farming systems” of the Limpopo Living Landscapes project), I focus on the joint effects of grazing and drought on the savanna rangelands in the Limpopo Region. This vegetation is exceptionally rich in species, and adequate levels of grazing are needed to maintain its high diversity. Thus, an ecosystem-based management is required to increase livestock production while conserving vegetation diversity and the functioning of the ecosystem to prevent rangeland degradation. Despite its importance, the relationships between the impact of drought and grazing on the vegetation have seldom been studied in the Limpopo region or in semi-arid savanna and grassland biome in general. For doing so, I use an experimental manipulation of precipitation (artificial drought) and grazing at the Syferkuil Experimental Farm, University of Limpopo – the DroughtAct experiment.
