- Description: This research study explores indigenous sorghum food management practices as a pathway towards sustainable food systems. The level of hunger is ever-increasing, and so is the global population. Regions less industrialized and developed suffer the most as they host growing populations and most of the worlds undernourished. Further intensified in this problem are a culling and unforgiving food systems run by a few conglomerates and a knowledge system driven by a histography of ‘othering’ even in its knowledge creation process. Although there exist institutions such as the United Nations Food and Agricultural programs, these remain relegated to policy and intergovernmental level, in the process, not being mindful of the real food issues faced at the grassroots level. This research study centralizes indigenous food practices to make sense of how rural and indigenous livelihoods such as those located in the Moshana village thrive and survive in a monopolized and urban-centred food climate like South Africa. By interviewing 12 participants, living, and taking part in the Moshana village food systems and employing stringent face-to-face semi-structured interviews, we present an indigenous food system as experienced and shared by Moshana Village Community members. The findings present an array of indigenous and food management practices, perspectives through an African ecological philosophical view. Conceptually inspired by the works of Vandana Shiva and many global south thinkers on seeds, grains and sustainable indigenous food systems, this study hopes to reinsert back the centrality of food in the growing field of African Sociology. The findings clearly show that elderly women are preserving the Sorghum knowledge and preservation processes. These practices have assisted the Moshana Village community members to cope with food shortages and lockdown restrictions during the strict COVID-19 lockdown in South Africa. The study concludes with clear need for the archiving and intergenerational communication of food management within the rural communities. , Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 2022

- Description: Estuaries occur at the interface between the terrestrial and marine environment and as such act as the last ‘filtering’ mechanism prior to nutrient pollution entering the adjacent ocean. This study focused on the Swartkops Estuary which is eutrophic and requires the removal of nutrients. The role of phytoplankton as nutrient filters and storage of nutrients by seagrass and salt marsh was investigated. This study found that phytoplankton temporarily took up a large percentage of dissolved inorganic nitrogen (max. 99%) and dissolved silica (max. 76%) and limited amounts of dissolved inorganic phosphorus (max. 18%). The amount of carbon, nitrogen and phosphorus stored by the salt marsh species Spartina maritima and Salicornia tegetaria and the seagrass species Zostera capensis were determined. It was found that the salt marsh grass Spartina maritima stored the most nutrients (149.61 ± 16.59 N g m-2 ; 105.44 ± 13.41 P g m-2 ; 1690.52 ± 168.90 C g m-2 ), while for the salt marsh succulent Salicornia tegetaria less nutrients were stored (27.01 ± 4.17 N g m-2 ; 22.97 ± 3.21 P g m-2 ; 458.66 ± 69.43 C g m-2 ). Zostera capensis also acted as a nutrient store (22.17 ± 6.94 N g m-2 ; 23.75 ± 4.70 P g m-2 ; 221.10 ± 26.74 C g m-2 ). The macrophytes were able to store nutrients for longer periods and thus prevent these nutrients from being exported into the adjacent ocean. On the contrary, phytoplankton uptake was temporary as the nutrients are released once the bloom decays. Without intervention there will be an increase of harmful algal blooms (HABs) and fish kills in the eutrophic Swartkops Estuary. Nutrient input from upstream wastewater treatment works, canals and stormwater run-off must be reduced. Conservation and management of the seagrass and salt marsh habitats is needed to ensure the long-term storage of nutrients , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: The year 1994 marked the dawn of the new, democratic South Africa. It also brought its own sets of challenges to the country. One such challenge was urban space. Regrettably, the new dispensation inherited still very much race-based urban areas. Urban space is understood to be a social outcome, the result of an historical process, an unequal accumulation of time, a presupposition, and a milieu of social production (Balbim, 2016). The distinguishing feature of urban space in South Africa is the phenomenon of exclusion, which causes deformity, and disappearance of urban structure. Exclusion has become a permanent visual reality in cities in which walled and gated communities divide the urban tissue and take up a large part of the urban space. The social action and struggle against the exclusionary process of globalisation such as the commodification and privatisation of urban space have always been on the international urban agenda. The study’s literature review suggests that government attitudes towards human settlements should change, particularly in terms of policymaking to combat the contemporary urban disparities such as fragmentation (also known as “enclave urbanism”). Fragmented cities do not function as a system but more and more as juxtaposed and uncoordinated fragments drifting apart (Bénit-Gbaffou, 2008). This has an immense impact on several sustainability influencing variables. Urban fragmentation can also have profound effects on human social dynamics and well-being by reducing the number of green spaces in cities. As loss of biodiversity continues, total core area and habitat cohesion decrease while edge density and shape complexity increase. Cities are required to be more sustainable, more accessible, and equal. Cities are now witnessing the emergence of real estate products that are far from achieving the previously mentioned goals, particularly inclusivity. Inclusivity in cities can be achieved by a contemporary urban development approach referred to as ‘inclusive urban space production’. Inclusive urban space production is a pro-poor approach that equally values and incorporates the contributions of all city stakeholders in addressing development issues, including the marginalised groups. The aim of this inquiry was, therefore, to examine factors that influence urban space production to generate a responsive urban space production model, referred to in this study as the “IUSP model”. The study also aimed at examining the role of the state and xx other stakeholders involved in the production of urban space, including the private sector and the community. Participation by all of them is essential to enhance inclusive urban space production for sustainability. A theoretical model for inclusive urban space production was developed based on an intensive literature review. Also, a concurrent partially mixed method design was employed in this inquiry. A study of Waterfall City was conducted to understand exclusive developments and their effect on the larger urban system. And a survey questionnaire was disseminated using random sampling. This was to measure the postulated model. Results from these two concurrent approaches were merged to yield the final model. The findings from the case study were analysed using ATLAS.ti and the findings from the survey questionnaire were analysed using several analyses techniques including EFA, correlation and regression. Both sets of results indicated that the intention to promote inclusive developments is predicted by seventeen dependent variables categorically presented under urban development characteristics, exclusive development enablers, inclusive development barriers, and sustainability criteria. The results of this inquiry are significant because they bring together the interdisciplinary perspectives to discern comprehensively the idea of inclusivity and sustainability in urban space production. The responsive model developed as a key product of this study aims to assist policymakers, planners, designers, landscapers, and developers as a guideline for facilitating inclusive and sustainable urban development. , Thesis (PhD) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: Lions are apex predators that play a vital role in the ecosystem. They regulate prey species through predation and other non-consumptive means. Factors that have influenced the decline of lion populations across Africa in the last half century, are loss of habitat, human wildlife conflict and the depletion of prey species. Extensive reintroductions of lions have been conducted across South Africa in order to restore their numbers in protected areas. The Pilanesberg National Park (PNP) was one of many protected areas that reintroduced lions. Their numbers were well documented by management until 2005 where they lost track of the population numbers. During this unfortunate period, there was an observed decline in prey numbers. The aim of this dissertation was to estimate the abundance, movement, and sex ratio of lions, in PNP. Abundance, movement, and sex ratio were determined by a three-month intensive lion survey. The location of each lion encounter was recorded on a mobile device which had an application installed called Cybertracker (v3). Photographs were taken of each Lion to build identification kits. For the data analysis, I used the Bayesian spatial explicit capture-recapture (SECR) model. This model takes time, space, and the robustness of an individual lion into account. Robustness is the measure of how well a lion maintains their functionality, when various stressors are applied (Harmsen, Foster, & Quigley, 2020). The estimated lion population in PNP was 44 lions (>1 year) with a density of 8.8 lions per 100 km2 . The estimated mean home range size of male lions was 279 km2 with a highest probability density (HPD) range of 179 – 385 km2 . The estimated mean home range of female lions was 191 km2 with a HPD range of 135 – 262 km2 . The larger home range size for male lions and smaller home range size for females is found v throughout the African continent in protected areas. The estimated sex ratio was 0.9♀:1♂, which is unexpected as PNP sex ratios between male and female lions is usually 2♀:1♂. A future sampling design for PNP was produced from the completed lion survey dataset. I drove a total of 7350 km and evaluated the influence of varied sampling efforts (i.e., kms driven) on precision estimates and relative bias for abundance, movement, and sex ratio. I found that a minimum of 4 000 km was needed to adequately estimate the lion abundance, movement, and sex ratio in this small fenced protected area. These findings can be used to help guide management to the most cost-effective sampling method and still obtain accurate estimates for monitoring lions. By showing management what is required for appropriate lion surveys this might help improve future monitoring. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Management, 2022

- Description: The treatise and proposed project deal with the creation of spaces rooted in the culture of a place, its identity, memory and meaning in the form of a contemporary regional archive and museum space for the context of Swellendam’s historical ribbon. The treatise seeks to find a strategy for a contemporary, yet regional specific, intervention in a traditional context and attempts to fulfil the creation of a place of culture, identity, meaning and memory. The methodology used for this architectural treatise is qualitative. In order to establish an appropriate building type, Swellendam's history and contextual data were analysed, at the same time, selected literature and ideas were introduced to establish the project's value set. Methods and principles are extracted and reinterpreted by the design project. Among the various works of literatures/theories reviewed in this treatise is that of Jonathan Noble, Maurice Halbwach, and Kenneth Frampton, among others. This respective literature sets the basis of the project’s value set on place and identity, memory and meaning, and tectonics and materials. The town’s rich history, morphology and nature of physical context are selected as an appropriate site. Furthermore, the treatise explores museums and archives as building types. This is done through the comparison of precedents under the light of certain issues. From this, the building type’s activities and spatial, programmatical requirements are gathered. Amid this various information collected are a set of relevant principles. Therefore, a set of principles (approach to memory, meaning and identity; heritage and conservation; extracting from the existing/vernacular/context; and approach to light) is explored and precedents are used to represent and learn from principles. This design project goes through a series of iterations to fulfil the specific architectural concerns and to create architecture specific for the context (relation to place, culture, history and site). The final design attempts to be a sensitive intervention, neutral in form, that resembles a heterogenous culture and hybridity. It aims to represent the culture of its place while being a public museum and archive facility. , Thesis (MArch) (Professional) -- Faculty of Engineering, the Built Environment and Technology, School of Architecture, 2021
