- Description: Balancing water demand and supply in South Africa involves high levels of uncertainty. The Department of Water and Sanitation (DWS) is responsible for making decisions to either increase water supply or decrease water demand so as to ensure that sufficient water is available, when and where it is needed. However, no retrospective analyses of such decisions have been found. One way to assess such decisions is to evaluate the associated costs and benefits thereof. Therefore the primary aim of this study is to evaluate the costs and benefits of selected water supply options, and of the decision-making associated with those options. In order to achieve this purpose, four case studies were analysed within a mixed-methods research paradigm, which used both quantitative and qualitative methods, including unit reference value (URV) analysis, inter- and intra-case analysis and content analysis to examine the success of the decisions made. The four case studies were conducted on the Inyaka, Nandoni, Berg and De Hoop dams and their catchments. Firstly, estimated and actual project costs were compared using unit reference analysis and inter-case analyses. Secondly, the reduction of mean annual runoff (MAR) caused by invasive alien plants (IAPs) and the cost of clearing them in the dam catchments were evaluated using inter-case analyses. Information thus gathered was used together with data from DWS documentation and the results of interviews with ten key specialists, to analyse the decision-making process that led to the decision to build De Hoop Dam (the most recent case study). The rational decision-making model (RDMM) was used as a framework within which to analyse and evaluate this decision-making process. This study has also demonstrated how the RDMM can be used to assess decision-making associated with water supply development. The results of this study show that there is considerable variation of estimated costs (at the time that the decision to build the dam was taken) in relation to the actual costs of building the dams and that Ministers were not put in a position to understand the full long-term costs or the opportunity costs of the proposed dams. Furthermore, the most recent IAP data (2008) shows that the impact on water security by IAPs could not offset the water security resulting from building each of the four dams. However, if IAP management is not continued in these catchments, the projected reduction of MAR by IAPs will compromise water security within 45 years. Given the almost exponential spread and densification of IAPs, together with their long-term impact on MAR and increased costs of controlling them, it is clear that IAP management should have been factored into water supply decision-making from the outset. In the analysis of the decision to build the De Hoop Dam, the results show that while the decision-making process that culminated in the decision to build the dam did not follow the steps of the RDMM, DWS appears to have followed a somewhat similar approach. It was found that while there was a need for the provision of additional water in the Olifants catchment, this need was overstated and the resulting overestimation caused the scale and size of the dam to be larger than it could and probably should have been. Additionally, it appears that DWS‘s decision to build the De Hoop Dam themselves, rather than having it built by the private sector, may have been less than optimal. It is recommended that, in future decision-making, DWS needs to incorporate multiple alternative options into the same solution, and to ensure that decision-makers are put into a position to make informed decisions, including adequate consideration of externalities. Furthermore, DWS needs to employ decision-making models such as the RDMM to facilitate retrospective analyses to improve their institutional knowledge. Keywords: water resources management, dams, invasive alien plants, decision-making, unit reference values, rational decision-making model.

- Description: My collection of stories explores the intersection of the human body and the body of text via the tropes of disease and animality. Drawing on my experience of living with tuberculosis for many years, I attempt to write disease differently – not merely to be survived, overcome, cured, eradicated, but as something to be embraced via the Deleuzian affirmation of being worthy of what happens to us. Taking my cue from Sontag, I use a creaturely approach to writing, “an infinitely varied register of forms and tonalities for transporting the human voice into prose narrative”, emphasising the shared embodiedness of humans and animals so as to challenge the omnipotence of thought that subjugates and colonises the body as exclusively human.

“Just trying to live our lives”: gay, lesbian and bisexual students’ experiences of being “at home” in university residence life

- Description: Higher education in South Africa is faced with a paramount task to help erode the social and structural inequalities that have been inherited from the Apartheid system (Department of Education 1997; Council on Higher Education 2000:12). The findings from the Soudien Report (2008:116-117) point out that the post-Apartheid higher education system in South Africa is characterised by various forms of discrimination and institutional cultures that marginalise some members of institutions resulting in pervasive feelings of alienation. In the South African higher education field, the concept of a “home” for all has been used by a variety of commentators to depict a vision of what transformed, inclusive higher education institutional cultures might look like. In this thesis, I interpret the experiences of residence life on the part of gay, lesbian and bisexual students on a largely residential campus. I ask how gay, lesbian and bisexual students experience being “at home” in the campus’s residence system. The thesis is based on 18 in-depth qualitative interviews with students who self-identify as gay/lesbian or bisexual who have experienced residence life on the campus for a period longer than six months. A wide literature exists on the concept of “home”. Drawing from many different disciplines including anthropology, history, philosophy, geography, psychology, architecture and sociology, I distil the essential features of “at homeness” as incorporating comfort, privacy, security, acceptance, companionship and community. The research was concerned to inquire into how central the idea of home is to human flourishing and then into how gay, lesbian and bisexual students are routinely denied many of the essential comforts associated with being “at home” that heterosexual students have the privilege of taking for granted.
