To my co-supervisor, Doctor David Braun, who offered valuable experience and advice in conducting a landscape-scale project, as well as providing the opportunity to interact with other experts carrying out landscape projects in areas outside of South Africa. This project would not have been possible without the generous funding supplied by the DST-NRF Centre of Excellence in Palaeosciences (CoE-Pal) and Palaeontological Scientific Trust (PAST). A huge thank you goes to Emily Hallinan who provided assistance during and after fieldwork, which included useful discussions around landscape archaeology and the analysis of the data, as well as the editing of chapters. A great deal of what makes these archaeological surveys that extra bit enjoyable is being given the opportunity to meet the local farmers of the area. The hospitality and kindness that was shown to us during our surveys by these farmers, particularly the Taljaard family who welcomed us into their homes and allowed us to conduct our research on their farm, cannot be underestimated. To Marie and Bill Hunt who offered their farmhouse to us as accommodation for the duration of the field seasons. ix To those that helped in the field and offered invaluable advice and comments, Jess Robinson, Madelon Tuisenuis, John Almond, Alex Sumner, Alex Mackay and everybody else who played a role in aided in the completion of this thesis. And finally, to Candice Koopowitz,
