- Description: South Africa’s disappointing economic performance over the last decade has resulted in a socio-economic crisis, with unemployment and inequality rates being of the highest rates anywhere in the world. Furthermore, unemployment is concentrated among the young, unskilled, and previously disadvantaged population posing a considerable threat to South Africa’s new democracy. Internationally, a method to absorb job seekers into the economy is to make small business the engine-room of economic growth and development. Consequently, the South African Government has identified in its National Development Plan the establishment of small businesses as a priority, including the development of small businesses in rural and marginalised communities. As rural communities in South Africa experience systemic problems such as the lack of infrastructure, financial capital, skills and potential markets, establishing enterprises in rural settings is often more complex than those more advanced parts of the economy elsewhere where fewer constraints exist. This makes the task of establishing and growing rural entities particularly challenging, suggesting bespoke policy and support is required. This study analyses the literature to gain an understanding of economic development theory and how this intersects with and informs small enterprise development policy. It then looks at South Africa’s strategy and policy framework pertaining to enterprise development. Specifically, the literature examines the role of rural enterprise development to establish whether this enables people to move out of poverty or further entraps people in poverty. The study collates data from a rural and marginalised community through observation and interview techniques. Firstly, multiple in-depth interviews were conducted with nineteen entrepreneurs in a rural community to collect data on business opportunities and explore the type of support entrepreneurs would require from government. Secondly, a focus group interview was conducted with entrepreneurs that had ii experienced institutional support to understand how well current policy and programmes support rural enterprise development. The primary data was analysed in conjunction with the literature on economic theory and enterprise development using the technique of triangulation to avoid logic leaps and formation of false assumptions. The insights and findings from the analysis reinforced certain facts within the body of knowledge pertaining to enterprise development, but there were also some interesting new insights that emanate from the data. South Africa has been able to introduce a wide range of policy initiatives and has multiple programmes and strategies to support small enterprise development. It has achieved firm success and impetus as well as experiencing certain failures. The study clearly highlights both and makes recommendations to improve policy promoting rural enterprise development as a means to alleviate poverty. , Thesis (PhD) -- Faculty of Business and Economic Sciences, School of Management Sciences, 2020

- Description: Land and ethnicity continue to condition contestations in relation to belonging amongst rural Zimbabweans. The colonial era defined Zimbabwe’s land politics in a highly racialised and ethnicised manner. Racially, the colonial era gave birth to white-owned fertile farm lands, while blacks (or Africans) were resettled in agriculturally-unproductive Reserves, later referred to as communal areas in the post-colonial era. Though they were initially created with a segregatory and oppressive intent bent on disenfranchising native Africans, the Reserves became a definitive landscape embedded in ethnic and ancestral belonging for the autochthonous Natives. The Reserves were created exclusively for autochthonous Africans, and the colonial administration ensured that foreign migrant Africans recruited mainly as covenanted labour from nearby colonies would not be accommodated and consequently belong in Reserves. Migrant Africans were instead domiciled in white commercial farms, mines and urban areas, and deprived of land rights accorded to the autochthones. In the case of white farms specifically, the labourers experienced a conditional belonging (to the farm). This overall exclusionary system was later inherited and maintained by the post-colonial Zimbabwean government, up until the year 2000. Zimbabwe’s highly documented Fast Track Land Reform Programme (FTLRP) from the year 2000 did away with the entrenched racial bifurcations of land, as white commercial farms became fast track farms. However, it did not undercut the existence of communal areas. The FTLRP had a profound effect on the lives of commercial farm workers, particularly those of foreign origin who had no other home or source of livelihood to fall back on after fast track displacements. Some though sought to move into communal areas, from which they had been excluded previously. Within this context, most scholarly studies of the post fast track period ignore the plight of former farm workers especially those that moved to, and into, communal areas. This ethnographic study, specifically of former farm workers of foreign origin in Shamva communal areas, therefore seeks to contribute to Zimbabwean studies in this regard. It documents and examines the perceptions, practices and lived experiences of former farm workers of foreign origin now residing in the Bushu communal areas of Shamva, and how they interface with Bushu autochthones in seeking to belong to Bushu. This is pursued by way of qualitative research methods (including lengthy stays in the study sites) as well as through the use of a theoretical framing focusing on lifeworlds, interfaces, belonging, othering and strangerhood. Key findings reveal that belonging by the former farm workers in Bushu entails a non-linear and convoluted process characterised by a series of contestations around for instance land shortages, limited livelihood strategies and cultural difference. This project of belonging does not entail assimilation on the part of the former farm workers, as they continue to uphold certain historical practices, leading to a form of co-existence between the autochthones and allochthones in Bushu. In this way, the former farm workers seem to develop a conditional belonging in (and to) Bushu, albeit different than the one experienced on white farms in the past. , Thesis (PhD) -- Faculty of Humanities, Sociology, 2021

- Description: This study was aimed at exploring the teaching and learning of Euclidean Geometry in five selected senior secondary schools in the O R Tambo Coastal District of the Eastern Cape, South Africa. The literature review was based on existing knowledge in the teaching and learning of Euclidean geometry. The study was built on analyzing the effective teaching strategies based on the teacher’s Pedagogical Content Knowledge (PCK) in Euclidean Geometry (EG). Shulman and Ma’s perspective on teachers’ competencies and knowledge of Mathematics was used as the theoretical framework of the study. A mixed-methods sequential explanatory design was adopted for the study. A purposive convenience sampling technique was used to select research sites and participants. The main instruments used were questionnaires, semi-structured interviews, classroom observation schedules, and document analysis. Quantitative data was analyzed descriptively utilizing tables and graphs. Qualitative data were analyzed using thematic data analysis. The various findings were interpreted through the literature and the theoretical framework. It was found that learners have a poor foundation in geometry and the methods teachers employed to teach Euclidean Geometry were inappropriate. Recommendations and suggestions were made. It is hoped that these recommendations would be noted by the appropriate stakeholders to ensure that improvement in the teaching and learning of Euclidean Geometry is achieved in our secondary schools to help matriculates’ obtain good marks in the final certification examination.

- Description: This study was an appraisal of selected support services rendered by social workers to older persons in De Aar Service Area, Northern Cape Province in South Africa. The study endeavoured to achieve the following specific objectives: i) to appraise the nature and extent of the existing support services rendered by social workers to older persons; ii) to explore challenges experienced by older persons receiving support services from social workers; iii) to establish strategies that can be adopted by the Department of Social Development to restructure its interventions to enhance the services rendered to older persons; iv) and to assess measures that can be adopted by the service beneficiaries to ensure that they receive quality services. The study was premised on the theoretical lenses of sociology of weak ties (SWT) theory, Maslow’s Hierarchy of Needs model, and Social Exchange theory. The study was prompted by the growing number of elderly people who need the support services rendered by social workers as well as community based care. Methodologically, the study used a qualitative paradigm and was thus guided by the research design which was a case study complemented by explorative and descriptive study design types. The data was collected through in-depth one-on-one interviews, focus group discussions and key informants to strengthen the qualitative aspect of the study. This current study used a probability sampling method, specifically a purposive sampling technique, to purposefully select a study sample that has all the characteristics needed to contribute immensely to the phenomenon under study. Using this techniques, thirty-eight (38) participants were selected comprising sixteen (16) elderly persons who were 65 years and above, sixteen (16) Old-age Centre Caregivers, three (3) Generic Social Workers, and three Service Managers. Data was analysed qualitatively through thematic analysis, and revealed among other findings, that the social workers render extensive support to the older persons in De Aar Service Area, they do monthly assessments, conduct research, liaise with various stakeholders such as the DSD, Department of Health, SASSA, Caregivers, Older Persons (as service beneficiaries) and Municipalities in a bid to empower and improve the welfare of older persons. However, the study also showed that older persons receiving support from the Social Workers are experiencing various problems such as chronic illnesses and stress due to old age. Most importantly, the study gaps in the services rendered to older persons by Social Workers are identified and as a result, strategies to cover the gaps are suggested therefrom. , Thesis (MSoc Sci) (Social Work) -- University of Fort Hare, 2021

- Description: Everyday activities of communities are dependent on services provided by the local municipality, district or regional council and the national government. These activities range from water flowing freely from taps, a roof to hide under, and a clean and healthy environment, just to name a few. The Batho Pele principles were introduced to ensure that these services are provided for the benefit of the people. They were introduced to make sure that people are involved in the process of service delivery so that services are exactly what they need. It is important to note that the Batho Pele principles inform service standards and a customer care charter. This means that the government or providers of service listen to citizens’ views and take them into account when making decisions about service delivery. Informing service standards and a customer care charter also means that service providers or the government responds swiftly and sympathetically when the service standard falls below the promised standard. The problem occurs when citizens are not being consulted about the type of services they are entitled to. The citizens of Buffalo City Metropolitan Municipality had an issue with how services are provided. They stated that even though service delivery was improving, the manner in which these services were provided was not satisfactory. They complained that they were not asked about what they needed and what their priorities were. Moreover, they stated that when they complained, they did not receive an effective response. The main objective of this research was to establish citizens’ experience with consultation and redress as core functions of the Batho Pele Principles. Furthermore, this research sought to establish important elements of proper citizen consultation and redress in the literature, to determine the extent to which these principles are adopted in in BCMM, to establish the effects of current consultation and redress practice on citizens’ trust in their local government and to make recommendations on effective approaches to consultation and redress. The theories that guided the study are the agency theory, the social equity theory and the procedural justice as a derivative of social equity theory. The legislative framework includes the White Paper on Transforming Public Service Delivery (Notice No 1954 Of 1994), the Constitution of the Republic of South Africa, the Municipal Systems Act no 32 of 2000 and the Promotion of Administrative Justice Act 3 of 2000. The study used both the qualitative and quantitative methods. It also used a case study design. The study used a sample of 110 respondents and the data was collected using interviews, questionnaires and a focus group discussions. Analysis of data followed the narrative and descriptive paradigms. Most importantly, all the objectives of the study were met. , Thesis (MCom) -- Faculty of Management and Commerce, 2020

- Description: Literature has revealed that indigenous learners, especially in many African nations are subjected to learning school science in unfamiliar contexts. Learners in Namibia where this study was conducted are no exception. In consequence, learners experience cognitive conflict between school science and the experiences learnt at home and in the community. This is exacerbated, in part, by the fact that science teachers do not seem to know how to integrate indigenous knowledge in their science teaching. As an attempt to address this problem, some scholars call for the integration of indigenous knowledge into the science curriculum to provide a much needed context for learning science. It is against this background that this study sought to use the indigenous technology of dyeing and weaving baskets as a cultural tool to mediate learning of chemical and physical changes. Underpinned by the interpretivist and Ubuntu paradigms, the study employed a qualitative case study research design. The study was conducted in the Zambezi region in Namibia. Four grade 8 Physical Science teachers, an expert community member, and a critical friend were involved as participants in this study. Data were gathered using semi-structured interviews, workshop discussions, participatory observation, and journal reflections. Vygotsky’s socio-cultural theory and Mavhunga and Rollnick’s topic specific pedagogical content knowledge were used as theoretical and analytical frameworks, respectively. A thematic approach to data analysis was employed to come up with sub-themes and themes. The findings of the study revealed that all the participating teachers in this study had never been exposed to ideas on how to integrate indigenous knowledge in their science teaching. As a result, they all embraced and valued the indigenous technology of dyeing and weaving as relevant and useful in the teaching and learning of chemical and physical changes. This study recommends that there is a need to empower science teachers on how to integrate indigenous knowledge in their science teaching in order to make science accessible and relevant to their learners’ lived worlds. , Thesis (MEd) -- Faculty of Education, Education, 2021

- Description: Worldwide, cryptic species, which comprise two or more distinct species that are classified as one due to their morphological similarity, are more common than previously thought. In South Africa, the chubbyhead barb, Enteromius anoplus (Weber, 1897), is the most widespread freshwater fish species. The widespread occurrence of this species across different river basins raised questions on its taxonomic status due to the likely occurrence of hidden diversity. This further raised the need to evaluate the ecological patterns associated with likely occurrence of such hidden diversity. Phylogenetic analyses of the cytochrome b gene of E. anoplus populations across South Africa revealed the occurrence of four genetically distinct species. These findings supported the restoration Enteromius cernuus (Barnard 1943) stat. rev. from the Olifants River system; the restoration of Enteromius anoplus sensu stricto (Weber 1897) stat. rev. from the Gouritz River system; the redescription of Enteromius oraniensis (Barnard 1943) stat. rev. from the Orange River system; and the description of a new species, Enteromius mandelai sp. nov. from the Eastern Cape rivers. Analyses of morphometric and meristic data revealed that these species were differentiated based on barbel length and number of lateral line scales. Ecological studies on Enteromius mandelai were conducted within headwater streams of major river systems in the Eastern Cape region. These headwater streams had different catchment characteristics ranging from near-natural to anthropogenically-perturbed mainly due to agriculture-related disturbances and invasion of riparian zones by non-native plants. Stable isotope analysis provided evidence of trophic plasticity for E. mandelai across the different headwater streams. Specifically, E. mandelai exhibited large isotopic niches in agriculture-disturbed headwater streams, whereas small isotopic niches were observed in headwater streams invaded by non-native plants. Because of the evidence of trophic plasticity for E. mandelai, this study further hypothesized that this species would exhibit variable environmental niche patterns related to its distribution, abundance and the presence of contra-specifics due to different abiotic factors across its range. Enteromius mandelai was generally most abundant at sites with high total dissolved solids and sand substratum, which was characteristic of large pool habitats, and least abundant at sites with high turbidity. In the Great Fish River, E. mandelai occurred as the only species in most headwater sites, whereas in the Keiskamma and Buffalo River systems, it co-occurred with Amatolacypris trevelyani and Sandelia bainsii. Enteromius mandelai was, nevertheless, found to be ubiquitous together with having wide environmental niches, and exhibited no discernible patterns in its habitat associations. The taxonomic re-evaluation of the E. anoplus complex, which provided evidence of the existence of new species, has implications for the biogeographic zonation of the ichthyofauna of the Cape Fold Ecoregion (CFE), Amathole-Winterberg Highlands Ecoregion (AWHE) and the Southern Temperate Highveld Ecoregion (STHE). For example, the currently recognised southern limit of the STHE, which encompasses the AWHE, is based on the occurrence of E. anoplus, Enteromius pallidus and Labeo umbratus. However, evidence from this and other recent studies indicate the occurrence of either new species or distinct lineages in the southern-most section of the STHE, which is consistent with the patterns observed in the CFE. Comparison of taxonomic composition showed that species in the eastern part of the CFE were similar to species in the AWHE and the southern-most section of the STHE. Because of the close affinities among most of the new taxa in these regions, this study proposes that the current delimitation of the CFE should be reviewed by extending it to include the AWHE and sections of the STHE. , Thesis (PhD) -- Faculty of Science, Ichthyology and Fisheries Science, 2021

- Description: The current situation of teaching and learning science in Namibia is of great concern since it does not seem to take into consideration learners’ socio-cultural backgrounds. As a result, learners are finding that science is not relevant to their everyday life experiences and hence are not motivated to learn it. This is compounded in part by the fact that the Namibian curriculum seems to be silent on how science teachers should include learners’ socio-cultural backgrounds, for example, local or indigenous knowledge in their teaching repertoires. It is against this background that in this study I explored how mobilising the cultural practice of a traditional blast furnace (mudukuto) as an approach enables and/or constrains learners’ motivation to learn science and make sense of the concept of malleability. This is a qualitative case study underpinned by a combination of interpretive and Ubuntu paradigms. It was carried out in a rural school in Namibia, Kavango West Region, where I am currently teaching. The participants in the study were grade 9 learners and one expert community member. Focus group interviews, participatory observation, learners’ reflections, and stimulated recall interviews were used to gather qualitative data. Vygotsky’s socio-cultural theory was used as a theoretical framework and Ogunniyi`s Continuity Argumentative Theory (CAT) was used as analytical framework or lens to analyse the data. A thematic approach to analyse data was employed. That is, qualitative data were analysed inductively to come up with sub-themes and themes. The findings of the study revealed that the traditional furnace motivated the learners involved in this study to learn science and learners were able to extract science concepts on malleability from the traditional practice. The implication for this study is that when science is related to learners’ daily life or real-world experiences, they are enabled to bridge the gap from what they learn at home or in the community with school science. The study thus recommends that teachers should make an effort to integrate local or indigenous knowledge and practices to make science accessible and relevant in their classrooms. , Thesis (MEd) -- Faculty of Education, Education, 2021

- Description: South Africa has experienced a high and rising burden of non-communicable diseases (NCDs) and lifestyle risk factors over the past decade. Health as a category of human capital is generally ex-pected to influence an individual’s labour supply and productivity. Despite the increasing burden of non-communicable diseases, the high rate of economically inactive population and persistent wage inequalities in South Africa, there is limited empirical research on the effect of NCDs on labour force participation, employment status and wage differentials. Given this, the main object-ive of this study was to determine the effects of NCDs on three labour market outcomes: labour force participation, employment status and wage differentials in South Africa. This was divided into three major analytical objectives. Data used was extracted from the five waves of the National Income Dynamics Study, a nationally representative survey collected by the South African Labour and Development Research Unit (SALDRU). Several econometric tests, including cross-sectional data analysis, panel data analysis and the Blinder-Oaxaca decomposition methods, were used in the study. The first analytical objective focused on estimating the effect of lifestyle risk factors on labour force participation through NCDs by gender. Endogenous multivariate probit models with a recur-sive simultaneous structure were employed as a method of analysis. The empirical findings suggested that NCDs and associated risk factors have detrimental effect on labour force participation. The analysis was further expanded to analyse the effect of gender differences, considering that the effect of NCDs may be gender-specific. The results revealed that the effect of stroke and heart diseases were significant only for men, while diabetes and high blood pressure were only significant for women. The results also emphasised the significant indirect influence of obesity, physical inactivity, and alcohol consumption on labour force participation through NCDs, especially for men. The second analytical chapter focused on investigating the effect of NCDs on employment status – that is, those employed, unemployed and economically inactive in the population of South Africa by gender. The estimation technique known as generalised linear latent and mixed methods (GLLAMM) was employed to fit the multinomial logit model with correlated random intercept. The findings suggest that NCDs affect the economically inactive population significantly relative to those employed, and the magnitude is larger for women than for men. There was no significant difference found in the effect of NCDs on the unemployed relative to the employed segment of the population. In addition, the results revealed gender differences on the effect of NCDs on employment status and that stroke had a significant influence on the employment status of both sexes, while heart diseases had significant influence only in men, whereas diabetes had significant effects only in women. The last analytical chapter focuses on estimating the effect of NCDs on wage differentials in South Africa by gender. The recentred influence function regression model and Blinder-Oaxaca de-composition with RIF were used in the chapter. The empirical results revealed that the effect of NCDs on earnings differ by gender. It was found that women with NCDs earn less than those without NCDs, while men with NCDs were found to earn more than their counterparts without NCDs. The results further revealed that women with NCDs suffer from wage discrimination in South Africa. The policy implications of this study are gender-specific. The results highlight the necessity for undertaking a massive awareness campaign regarding the prevention and control of NCDs, espe-cially among women. This can be achieved through specific female health programmes, including maternal healthcare. The findings of the study imply largely that calls for gender-responsive health approaches which take into account gender-specific needs and priorities should be promoted, compared to a blanket approach. In addition, there is a need for the government to complement education policies to promote labour market outcomes. Policies aimed at increasing access to education should continue to improve access to higher education and so to enhance participation in the labour force and reduce wage gaps. , Thesis (PhD) -- Faculty of Management and Commerce, 2020

- Description: In Madagascar, as in several countries in the world, the invasion by four aquatic weeds (Pontederia crassipes Mart. (Pontederiaceae), Pistia stratiotes L. (Araceae), Salvinia molesta D.S. Mitch Salviniaceae) and Azolla filiculoides Lam. (Azollaceae) are among the drivers of environmental and socio-economic deterioration in aquatic ecosystems. Pistia stratiotes was first recorded on the island in the 19th century, and P. crassipes from the beginning of the 20th century, while S. molesta and A. filiculoides were only documented during in the 21st century. From the 1920s, botanists such as Henri Perrier de la Bathie and Raymond Decary were already aware of the dangers caused, in particular by P. crassipes in other countries, and raised the alarm, but little attention has been paid to these species. The aim of the research conducted for this thesis was to determine the distribution, socio-economic and ecological impacts of these four invasive alien aquatic weeds in Madagascar and to make recommendations for their control. First, the distributions of these four aquatic weeds were mapped. This mapping exercise compiled data from different sources including herbarium records, online data and field visits across Madagascar. The mapping study was undertaken from August 2015 to June 2020. Except for mountainous areas above 1800 m (Tsaratanana Massif, Ankaratra Massif and Andringitra Massif) where no data were available, all of Madagascar's bioclimates were invaded by at least one of the four aquatic weeds. In total, at least one species was recorded in 18 of the 22 Regions. Pontederia crassipes was recorded in 13 Regions, S. molesta in 14 Regions, P. stratiotes in 12 Regions, and A. filiculoides in 13 Regions. Herbarium records revealed the oldest record for P. stratiotes to be 1847, 1931 for P. crassipes, 1995 for S. molesta and there were no herbarium specimens for A. filiculoides prior to the start of the current study in 2015. We now know where these four weeds occur and how abundant they are. An objective of this research was to assess the impacts of the four invasive aquatic plants on the socio-economy of the island, mainly on rice production and fishing. Between 2016 and 2019, 102 households in three regions, Soanierana Ivongo, Foulpointe and Antananarivo, were randomly selected and questioned on the impact of these weeds in their aquatic ecosystems and their livelihoods such as fishing and rice growing. Surveys revealed that the four aquatic weeds significantly threatened household activities. On the east coast of Madagascar, the invasions of these four invasive species decreased fish and freshwater shrimp production by 82%. On the high plateau of Madagascar, they reduced rice yield by 30% despite requiring an additional expense of US$ 1,107/ha for control. Although farmers surveyed only used manual control to manage these weeds, they were receptive to other control methods, including integrated control using herbicides and biological control. Another objective of this research was to determine the ecological impacts of the four weeds and specifically if freshwater ecosystem functioning would return after control. To assess the ecological impact, between February 2017 to August 2019, on Lake Antsokafina, the following abiotic and biotic factors were considered: physico-chemistry of water, succession of macrophyte community and animal diversity. With the exception of turbidity, the values of the physico-chemical parameters of the water (pH, electrical conductivity, water temperature and turbidity), were similar between the infested zone and cleared zone. A study on the invasion process of aquatic weeds showed that the plant community succession of the lake changed over time in the areas that had been cleared. The submerged species Ceratophyllum demersum was the pioneer, followed by creeping species such as Echinochloa colona and Ipomoea aquatica, before the area was recolonized by aquatic weeds. Among the aquatic weeds, S. molesta was the most aggressive, covering 92% of the area one year after the start of the experiment. For animal diversity, bird, shrimp and fish community were assessed. The cleaning of the plots in the lake allowed the resumption of fishing activity providing 50 to 200g/catch for shrimp and from 0.25 to 0.5kg/catch for fish per person per day, while no catch was obtained in the areas infested by aquatic weeds were fishermen still attempting to harvest fish/shrimp from the aquatic weed infested areas. Three species of birds, Humblot’s Heron (Ardea humbloti), the white-faced whistling duck (Dendrocygna viduata) and red-billed teal (Anas erythrorhyncha) returned once the areas had been cleared. A manipulated outdoor as descriptor for laboratory experiment was conducted to determine the level and nature of competition of four aquatic weeds species against the indigenous floating fern, Salvinia hastata Desv. (Salviniaceae), using an additive series density model. It was shown that all four invasive species outcompeted S. hastata, with P. crassipes being 24 times more dominant, followed by P. stratiotes at 12 times, S. molesta at 8 times, and finally A. filiculoides at 1.2 times more dominant. This study provided direct evidence of the biodiversity impact of these four species and thus also provided an environmental argument for their control. Based on the findings of this study, a series of recommendations was formulated to manage the invasions of alien species in Madagascar with particular attention to invasive aquatic weeds.

- Description: In Madagascar, as in several countries in the world, the invasion by four aquatic weeds (Pontederia crassipes Mart. (Pontederiaceae), Pistia stratiotes L. (Araceae), Salvinia molesta D.S. Mitch Salviniaceae) and Azolla filiculoides Lam. (Azollaceae) are among the drivers of environmental and socio-economic deterioration in aquatic ecosystems. Pistia stratiotes was first recorded on the island in the 19th century, and P. crassipes from the beginning of the 20th century, while S. molesta and A. filiculoides were only documented during in the 21st century. From the 1920s, botanists such as Henri Perrier de la Bathie and Raymond Decary were already aware of the dangers caused, in particular by P. crassipes in other countries, and raised the alarm, but little attention has been paid to these species. The aim of the research conducted for this thesis was to determine the distribution, socio-economic and ecological impacts of these four invasive alien aquatic weeds in Madagascar and to make recommendations for their control. First, the distributions of these four aquatic weeds were mapped. This mapping exercise compiled data from different sources including herbarium records, online data and field visits across Madagascar. The mapping study was undertaken from August 2015 to June 2020. Except for mountainous areas above 1800 m (Tsaratanana Massif, Ankaratra Massif and Andringitra Massif) where no data were available, all of Madagascar's bioclimates were invaded by at least one of the four aquatic weeds. In total, at least one species was recorded in 18 of the 22 Regions. Pontederia crassipes was recorded in 13 Regions, S. molesta in 14 Regions, P. stratiotes in 12 Regions, and A. filiculoides in 13 Regions. Herbarium records revealed the oldest record for P. stratiotes to be 1847, 1931 for P. crassipes, 1995 for S. molesta and there were no herbarium specimens for A. filiculoides prior to the start of the current study in 2015. We now know where these four weeds occur and how abundant they are. An objective of this research was to assess the impacts of the four invasive aquatic plants on the socio-economy of the island, mainly on rice production and fishing. Between 2016 and 2019, 102 households in three regions, Soanierana Ivongo, Foulpointe and Antananarivo, were randomly selected and questioned on the impact of these weeds in their aquatic ecosystems and their livelihoods such as fishing and rice growing. Surveys revealed that the four aquatic weeds significantly threatened household activities. On the east coast of Madagascar, the invasions of these four invasive species decreased fish and freshwater shrimp production by 82%. On the high plateau of Madagascar, they reduced rice yield by 30% despite requiring an additional expense of US$ 1,107/ha for control. Although farmers surveyed only used manual control to manage these weeds, they were receptive to other control methods, including integrated control using herbicides and biological control. Another objective of this research was to determine the ecological impacts of the four weeds and specifically if freshwater ecosystem functioning would return after control. To assess the ecological impact, between February 2017 to August 2019, on Lake Antsokafina, the following abiotic and biotic factors were considered: physico-chemistry of water, succession of macrophyte community and animal diversity. With the exception of turbidity, the values of the physico-chemical parameters of the water (pH, electrical conductivity, water temperature and turbidity), were similar between the infested zone and cleared zone. A study on the invasion process of aquatic weeds showed that the plant community succession of the lake changed over time in the areas that had been cleared. The submerged species Ceratophyllum demersum was the pioneer, followed by creeping species such as Echinochloa colona and Ipomoea aquatica, before the area was recolonized by aquatic weeds. Among the aquatic weeds, S. molesta was the most aggressive, covering 92% of the area one year after the start of the experiment. For animal diversity, bird, shrimp and fish community were assessed. The cleaning of the plots in the lake allowed the resumption of fishing activity providing 50 to 200g/catch for shrimp and from 0.25 to 0.5kg/catch for fish per person per day, while no catch was obtained in the areas infested by aquatic weeds were fishermen still attempting to harvest fish/shrimp from the aquatic weed infested areas. Three species of birds, Humblot’s Heron (Ardea humbloti), the white-faced whistling duck (Dendrocygna viduata) and red-billed teal (Anas erythrorhyncha) returned once the areas had been cleared. A manipulated outdoor as descriptor for laboratory experiment was conducted to determine the level and nature of competition of four aquatic weeds species against the indigenous floating fern, Salvinia hastata Desv. (Salviniaceae), using an additive series density model. It was shown that all four invasive species outcompeted S. hastata, with P. crassipes being 24 times more dominant, followed by P. stratiotes at 12 times, S. molesta at 8 times, and finally A. filiculoides at 1.2 times more dominant. This study provided direct evidence of the biodiversity impact of these four species and thus also provided an environmental argument for their control. Based on the findings of this study, a series of recommendations was formulated to manage the invasions of alien species in Madagascar with particular attention to invasive aquatic weeds. These recommendations mainly concern the establishment of management structures and legal instruments such as the creation of a lead government agency at national level and a cross-sectorial invasive species advisory committee, which should review legislation and regulations related to invasive species. , Thesis (PhD) -- Faculty of Science, Zoology and Entomology, 2021

- Description: The Tsitsa River is the largest remaining river that is without a dam in South Africa, and so the government has pledged to install two major dams for irrigation and hydroelectricity, under the Mzimvubu Water Project. These dams are intended to supply water and electricity to surrounding communities as well as the large neighbouring urban areas of Mthatha and Tsolo. However, large areas of the Tsitsa Catchment (~494 000 ha) are degraded, posing the possibility that if these dams were to be created, they would inevitably fill with sediment and silt within a few decades. To address these issues, the Tsitsa Project was established in 2014 to co-ordinate actions by government, developers and local communities in order to restore the landscape condition and prevent soil erosion, as well as to improve the livelihoods of the people who live there (Fabricius, Biggs, & Powell, 2016). Research into the landscape condition as well and the environmental interactions with local communities are therefore highly necessary in order to guide restoration practices to their best effect. The economic necessity for livestock production in the catchment indicates its urgent need for a better understanding of its current effects on the catchment landscape and vegetation. The overall goal of this study is to contribute to the knowledge needed to manage the area in a sustainable way. This paper will therefore examine the key vegetation resources that support livestock production in an area of the Tsitsa River Catchment, by describing the various types that exist, and by determining their relative production levels of usable livestock forage. , Thesis (MSc) -- Faculty of Science, Institute for Water Research, 2021

- Description: This thesis shows the statistics of atmospheric gravity waves (AGWs) observed in the OI emission 557.7 nm at _97 km altitude using an all-sky imager based in Sutherland, South Africa (32.37_ S, 20.81_ E) in the year 2017. The wavelengths were determined using the propagation vector method, velocity was determined using the cross correlation of 1D FFT and the period was determined using the equation that relates wavelength and velocity. It was found that the horizontal wavelength in summer was almost evenly distributed between 10 and 40 km and for autumn, winter and spring were mostly between 10 and 30 km. The favoured speeds were between 40 and 50 m/s in autumn, as well as 30 and 50 m/s in summer, but the AGWs in winter had a bimodal speed distribution of 20 - 40 and 50 - 70 m/s. The majority of periods observed in all seasons were less than 20 minutes with a dominant peak of 5 - 10 minutes in autumn and spring. There was no favoured propagation direction for spring, but AGWs favoured a southeastward propagation in summer, and a southward propagation in autumn and winter. , Thesis (MSc) -- Faculty of Science, Physics and Electronics, 2021

- Description: Coastal mangrove vegetation at Mngazana continues to be threatened and reduced periodically due to unmonitored harvesting. Covering an area of 148ha, the Mngazana mangrove forest remains unreserved, thus, research on the Mngazana mangroves is essential in order to monitor their state and sustainable management. Since in-situ monitoring of mangrove areas is both challenging and time-consuming, remote sensing technologies have been used to monitor these ecosystems. This study was carried out to monitor the impact of deforestation using ASTER satellite images over ten years: from 2008 - 2018. Validation was carried out by comparing classification results with the ground-referenced data, which yielded satisfactory agreement, with an overall accuracy of 94.64 percent and Kappa coefficient of 0.93 for 2008; and in 2009, the overall accuracy was 88.62 percent and a Kappa coefficient of 0.85. While the overall accuracy of 95.08 percent and a Kappa coefficient of 0.92 for 2016 and 2018 were observed, the overall accuracy of 93.58 percent and a Kappa coefficient of 0.91 was yielded. NDVI and SAVI indices were used as monitoring indicators. The results obtained in the study indicated that the canopy density of the mangrove forest remained unchanged in the years under investigation. However, insignificant changes in canopy density were identified between 2009 and 2016. , Thesis (MSc) (Applied Remote Sensing & GIS) -- University of Fort Hare, 2021

- Description: The study examined the implementation of SADC health programmes, particularly the health protocol and its role to the advancement of health justice in the SADC region. Social driven regionalism involves member states adopting common policies in social policy areas that include; health, education and social protection. Therefore, the focus of this study was on regional integration-social policy interface and contribution towards socially equitable regional development with specific focus on health care provision. Since the 19th century development co-operation between countries has been informed by traditionalist views on regionalism, particularly the comparative advantage and the customs union paradigms. These anachronistic models have constructed a narrative suggesting that adopting trade-based regional integration schemes is a sustainable solution to fragmented markets and weak economies that are vulnerable to global economic trends. This antediluvian approach has produced forms of regionalism whose endeavour is the liberalisation of trade to the negation of human development. The SADC has experimented with this approach since the 1980s leading to the neglect of social policy and deepening human insecurity as shown by high mortality rates attributable to epidemics and low life expectancy in SADC member countries. Although neo-classical foundations are the socio-historical pivots of regional integration SADC has instruments that are centred on social actions aiming to promote citizens’ normative right to health. Thus, the fundamental strength with SADC regional social policy instruments is the incorporation of pro-poor commitments in systems of regional governance. While these social policies do not establish guarantees to the realisation of the right to health because they do have the politico-legal means to enforce such guarantees, they define regional agenda for justice in the context of deepening social challenges. This consequently makes the SADC region a site for norms that engender practices towards addressing the challenge of economic development and social transformation dichotomy. The existence of social policies arising from global health diplomacy means that the region has an opportunity to play a role as a vector for social justice through committing member states to equity and promoting social rights while providing brokerage needed for redistribution of public commodities. Using the qualitative approach, the study examined the implementation of SADC health programmes, particularly the health protocol, and the contribution to regional integration experience in the region. Narratives showed that SADC is facing enormous challenges in re-inventing regional co-operation towards health diplomacy. Although there is a confluence of factors militating against this form of regionalism, the fundamental contributory factor is lopsided regional integration favouring economic development ahead of social transformation. The architectural framework of SADC is trade-driven. Consequently, it lacks structures that can foster regional action on social questions that include; health infrastructure, health human resources, medical research and technology, vaccines production and procurement, regional health financing, civil society engagement towards achieving health justice in the region. The study has adopted the justice-driven regional health approach grounded on South to South co-operation principles and universalisation of health as the framework for understanding region and state-level interventions required to resolve intensifying social policy challenges including TB and HIV/AIDS. , Thesis (PhD) -- Faculty of Management & Commerce, 2020

- Description: Photodynamic antimicrobial chemotherapy (PACT) is a well-known antimicrobial therapy technique used against multi-drug resistant pathogens. In this study, the syntheses, characterization, photophysicochemical properties, and the applications of symmetrically and asymmetrically substituted cationic indium (III) porphyrins linked to silver/copper ferrite core-shell (Ag/CuFe2O4) magnetic nanoparticles (MNPs) as potential photosensitizers for PACT are reported. The synthesized complexes include axially modified porphyrins quaternized through an axial ligand. All the asymmetrically substituted porphyrins were linked to the NPs via an ester bond and the symmetrically substituted porphyrins were linked (peripherally and /or axially) via self-assembly (Ag-S and/or Ag-N). The impact of axial modification, peripheral substituents, conjugation to the NPs, the number of positive charges, and the chain length of the alkyl halides quaternizing agents on PACT efficacy and photophysicochemical properties of porphyrins were studied. High singlet oxygen quantum yields and antimicrobial log reductions were observed. Lipophilicity and hydrophilicity of the porphyrins were also studies, where the complexes quaternized with methyl iodide showed relatively high hydrophilicity character. Upon in vitro PACT studies, the quaternized complexes were observed to have 0% viable colony, signifying their effectiveness. Moreover, the highest log reductions of 9.27 were observed against S. aureus and 9.58 were observed against E. coli. The findings from this work delineate that singlet oxygen generation alone is not a distinct factor on the PACT efficacy of the porphyrin complexes, since some of the complexes have practically the same singlet oxygen quantum but different PACT activity. However, other contributing factors including water solubility play a significant role. , Thesis (MSc) -- Faculty of Science, Department of Chemistry, 2021

- Description: Heavy metal ions are elements that are discharged into water streams from municipal or industrial waste. In abundance, they can be threating to the environment and human health. Amongst other several convention methods, adsorption has been proven to be the most effective method in the removal of heavy metal ions from wastewater. The aim of this research was to fabricate electrospun polyacrylonitrile (PAN) nanofibers and modify their surface to improve the adsorption efficiency for Chromium and Cadmium metal ions from synthetic wastewater. Electrospun nanofibers PAN nanofibers were fabricated via electrospinning process though careful monitoring of its parameters and modified via two-step process: hydrolysis with sodium hydroxide (NaOH), hydrochloric acid (HCl) and ethylenediamine (EDA). The morphologies, functional groups, thermal stability, chemical composition and crystallinities or amorphous structures of the nanofibers were characterised by Scanning electron microscopy (SEM), Fourier-Transform Infrared spectroscopy (FTIR), Thermogravimetric analysis (TGA), Energy dispersive X-ray analysis (EDX) and X-ray diffraction (XRD), respectively. The experiments were conducted in batch tests to analyse the effect to pH, contact time and initial concentration of the solution. Ultraviolet-Visible spectroscopy (UV-Vis) was used to analyse the concentration of metal ions. The adsorption equilibrium was reached after 120 min with a maximum adsorption capacity of 301.1 mg/g for Cd(II) ions and 195.02 mg/g for Cr(VI) ions. The adsorption capacity increased with increasing pH and initial concentration of the solution. The adsorption capacity of Cd(II) and Cr(VI) ions was higher at pH 8 and 10, respectively. The equilibrium data was best described using Freundlich isotherm with a maximum adsorption capacity for Cd(II) ions than Cr(VI) ions. Pseudo-second order kinetic model best fitted both heavy metal ions with R2 value of 0.99 for Cr(VI) ions and 0.67 for Cd(II) ions. Heavy metal ions were desorbed from the nanofibers after one regeneration cycle with an equilibrium concentration of 4.83 mg/L for Cr(VI) ions and 43.06 mg/L for Cd(II) ions. , Thesis (MSc) (Chemistry) -- University of Fort Hare, 2021

- Description: Government subsidies are becoming more prevalent on the African continent. Subsidies allow the government to intervene in markets to incentivise more investment into nascent and struggling industries by improving the efficiency of firms in such industries. As such, subsidies form an essential part of some African countries’ industrialisation policies. However, the use of subsidies faces a challenge because of the prohibition contained in the World Trade Organisation’s (WTO) Agreement on Subsidies and Countervailing Measures (SCM Agreement). The SCM Agreement prohibits the granting of subsidies that are contingent on export performance or the use of domestic over imported content. While African countries have not faced challenges in the WTO for their use of these subsidies, this may change with the operation of the African Continental Free Trade (AfCFTA) Agreement. This is because the AfCFTA Agreement localises the WTO’s rules on subsidisation. This study critically examines the provisions in the AfCFTA Guidelines on the Implementation of Trade Remedies that regulate the use of export subsidies and subsidies contingent on the use of domestic content. It discusses how the absolute prohibition of these subsidies in the AfCFTA Agreement is not the most effective way to regulate their anti-competitive effects in the African continent. Specifically, this study discusses the role that competition policy might play in ensuring that export subsidies and local content subsidies are regulated in a manner that suits Africa’s context. Ultimately, this study concludes and recommends that the AfCFTA must develop unique rules to regulate subsidies in a way that caters to the needs of the continent. , Thesis (LLM) -- Faculty of Law, Law, 2021
