- Description: There have been several attempts by the South Africa government to improve the agricultural productivity on smallholder farms since the end of apartheid. In spite of the government support, agricultural productivity has stagnated for several years across the Eastern Cape rural communities including Mthatha and Qamata. The aim of this study was to understand the roles played by irrigation adoption and market participation in addressing poverty reduction and shared prosperity levels of smallholder farmers in Eastern Cape of South Africa. Data were collected using purposive and random sampling approach through the use of the snowball method. To collect data, a questionnaire was designed and administered through face-to-face interviews. Overall, 200 farmers were interviewed both at Mthatha and Qamata irrigation scheme to represent the farmers in the area. The collected data were analysed using both parametric and non-parametric methods. The non-parametric methods used include descriptive analysis, estimation of gross margins as a proxy for profitability. The Stochastic Frontier Analysis (SFA), Binomial Logistic Regression (BLR), Ordinary Least Squares (OLS), tobit censored regression and propensity score matching (PSM) were the parametric methods used in the study. Profit efficiency was measured using the normalized transcendent logarithmic profit frontier approach (Cobb-douglas). Stochastic Production Frontier (SPF) technique was used to determine the technical efficiency of individual farmers and to identify the major factors that influence technical efficiency. Binomial logistic regression was used to determine factors affecting irrigation adoption and market participation among smallholder farmers. OLS was used to estimate the impact of institutional characteristics, socio-economic and agronomic factors on smallholder farmers’ level of market participation for selected crop enterprises. Lastly, tobit regression and propensity score matching (PSM) analyses were used to estimate the impact of irrigation technology adoption on poverty reduction in the province. The results of the descriptive statistics of the overall sample revealed an average age of 61 years, and mean household size of 4.6 persons with majority of the household head having at least obtained some primary school education (59.5percent). Most of the household heads interviewed were men (68.5percent). Most farmers are single (65percent) with regard to their marital status. Farming is viewed as major source of livelihood for smallholders with an average income of R12523.37 for overall sample and income of R15559.80 and R5795.59 per crop season, respectively, for irrigators and non irrigators. Smallholder irrigators generated a higher gross margin of R7585.26, R21966.89 and R6266.07 from maize, cabbage and potato enterprises, respectively, compared to their non irrigator counterparts in maize (R131.39), cabbage (R10938.04) and potato (R3433.31) enterprises. The results of the frontier profit model revealed mean profit efficiency of 90percent, 99.99percent and 99.99percent, respectively, for maize, cabbage and potato.The binary logistic regression model for irrigation adoption indicated that years in school, cooperative membership, off-farm income, credit access and distance to market significantly explain smallholder farmers’ irrigation adoption decision. On the other hand, age of household head, market support, farm size, livestock income and distance to market were the key variables that accounted for smallholder farmers’ market participation adoption behaviour. The findings from the stochastic production frontier (SPF) indicate that smallholder farmers are technically efficient in maize and cabbage enterprises both at 99.99percent. Lastly, the findings from the Tobit regression and propensity score matching are consistent across the two methods, suggesting that being a member of irrigation adoption has a positive significant impact on income of smallholder farmers. Irrigation and market participation appear to have a significant and positive impact on smallholder poverty reduction (measured by crop income) for those farmers engaged in them. The findings from this study provide useful practical insights for policy makers, farm advisers and researchers in the design of effective and efficient policies, programmes and projects which can affect the adoption of irrigation technology and market participation.

- Description: The construction industry (CI) is well known to be one of the most dangerous industries in South Africa (SA) due to the complex nature of construction activities, advancement in technologies and an aging workforce, emphasising the need for training. Over the past two decades, the industry has come under the spotlight regarding Health and Safety (H&S). The Occupational Health and Safety (OH&S) Act 85 of 1993 and Construction Regulations (CR) 2014 as amended are the statutes that govern the H&S in the construction workplace. These statutes aim to provide minimum guidelines by which all operating in the industry should abide by in order to ensure the safety of all persons at work. A fundamental aspect of the OH&S Act and CR is for construction employers to assess occupational hazards and conduct risk assessments with remedies to mitigate or prevent such risks. Furthermore, employers are compelled by law to ensure that employees are made aware of the risks at the induction stage, in addition to preventative measures associated with their work activities. Therefore, training forms the structure by which H&S in the workplace can be improved. Training in itself is not enough if it is not based on the employees’ needs as assessed. Training needs to be relevant and effective if it is to have a significant effect in the prevention and possible reduction in the number of occupational injuries and fatalities in the CI. A question that led to the basis of this research was why there were such poor H&S practices in the CI when the statutes clearly require the importance of training. This research is aimed at establishing the effectiveness of service providers relative to construction. Service providers offer services such as training, auditing, SHEQ management, and other H&S related matters. Of fundamental importance is that training has a direct or indirect influence on the health and safety (H&S) of employees in the workplace. Thus, this research aims to determine the effectiveness of training offered by these service providers relative to construction. The researcher utilised the quantitative data collection method to collect primary data from a sample surveyed through a questionnaire, whilst collecting secondary data from books, the Internet, professional journals, and articles. The sampled population consisted of service providers, health and safety practitioners, construction managers, supervisors, and workers, all from the Nelson Mandela Bay Municipal Area. The data was analysed quantitatively using the Statistical Package for Social Sciences (SPSS), ANOVA and the one-sample t-test. The literature reviewed and findings of this quantitative research amongst construction personal such as top, senior, middle management (TSMM), and general workers and labourers (GWL) in the Nelson Mandela Bay Municipal area formed the basis of this study. The study reveals that training offered by service providers was indirectly unrelated to construction. Furthermore, the study also showed that management concurred that there was a strong belief that language did not influence their ability to understand the contents of the training, which is mainly provided in English. The group believed that training from service providers were at the correct level. Alternatively, GWL were of the belief that language influenced their ability to understand the training received. The study also indicated that procurement of these service providers were not based on their skills, knowledge and background in construction. This may be attributed to the fact that management are more advanced in terms of education than GWL. Lastly, the study revealed that a significant number of Safety, Health and Environment (SHE) officers are in the process of registering with the South African Council for the Project and Construction Management Professions (SACPCMP), the professional body responsible for the registration of Construction Health and Safety (CH&S) professions. This study will conclude with findings, conclusions, and recommendations that will be valuable to construction companies relative to the services of service providers.

- Description: Ice-free regions in Antarctica provide natural laboratories for investigating and modelling change in landscapes and ecosystems. The terrestrial ecosystems in western Dronning Maud Land are potentially critical to improve current understanding of polar ecosystems, however, they remain poorly represented and under-protected. Lichen habitats were used to elucidate geomorphic-biological feedbacks that shape the landscape’s topography and biodiversity, which in turn promote environmental heterogeneity. Environmental parameters acting on two landforms were measured to determine the colonisation and growth of lichens in niche habitats. The habitats were identified and characterised, and topographic heterogeneity was found to control lichen colonisation. Micro-topographical niches provide the most stable environments for colonisation, and are preferred habitats. Lichen-habitat interactions were species specific, and closely related to insolation and moisture availability. The bidirectional relationships between rock weathering and lichen colonisation was ascertained. Results showed that lichens are good indicators of landform heterogeneity, but also promote landform heterogeneity. Given the habitat preferences of specific lichen species, they provide proxy to evaluating environmental responses, especially environmental change. The findings of this research are to be used as baseline data for future studies exploring ecosystem development in emerging landforms.

Visual narratives of division in contemporary Palestinian art and social space

- Description: This study analyses artworks by contemporary Palestinian artists that respond to visual narratives of division in social space from a perspective grounded in a South African context. The state of Israel is built on Historic Palestine. Political Zionism has created an ideological narrative of division that positions people of the Jewish faith as the rightful heirs to the land on which Palestinians have lived for centuries. In order to execute their vision of an exclusively Jewish nation state, the founding pioneers of political Zionism colonised and ethnically cleansed Historic Palestine, establishing Israel in 1948. To sustain the exclusive claim to Palestinian land, Israel has divided the space and the people in it at every possible level. The greatest testament to these efforts is the Israeli apartheid wall and checkpoint security system that can be described as a monumental visual narrative of division. With each second that passes, Israel claims more Palestinian land and expands on existing fences, walls and barriers. It is no secret that the Occupied Palestinian Territories are rapidly transforming into open-air prisons. Israel has stolen the Palestinian horizon line and replaced it with a concrete wall that blocks out light, vision and optimism. Within the shadows of these conflicted, traumatised sites of division, Palestinian artists seek openings, cracks and loopholes that signal the possibility for physical and psychological transgression of these seemingly impenetrable structures of division. I have developed a creative methodology that can be understood through the metaphor of ‘looking with the skin’ as a way to identify and analyse visual narratives of division and artistic responses to sites of division in Palestinian social space. Looking with the skin combines aspects of participant observation (specifically the emphasis on engaged fieldwork) from the discipline of Anthropology with the method of visual analysis from the discipline of Art History. In my application of this method through primary fieldwork conducted within the Occupied Palestinian West Bank Territory from 2013 and 2014, I have learnt that Israel’s colonisation, military occupation and system of apartheid directly impacts the ability of Palestinian artists to make and disseminate their work as well as the choice of content within their artwork. The artworks analysed in this thesis by the artists Khaled Jarrar, Y ael Bartana, Larissa Sansour, Hasan Darahgmeh, Fareh Saleh and Emily Jacir can be positioned in relation to artworks by artists based within a South African context, namely Thando Mama, Serge Alain Nitegeka and Doung Anwar Jahangeer. In this thesis I present a combination of my own photographic documentation of sites of division with the West Bank OPT in relation to the specific artworks made by the artists mentioned above. In my analysis of the photographic documentation and the artists’ work I highlight similarities, parallels, threads and intersecting narratives that connect different artists to one another and to the sites of division they are responding to within their artistic practice. This study carves a small conceptual pathway through ideological and physical walls from South Africa to Palestine through the study of contemporary art and visual culture.

- Description: This research aimed to reduce the mass of a purpose built eco-car wheel through the sequential use of structural topology and composites optimization software packages while investigating the changes in mass and strain behaviour resulting from altering component geometry, lamina shape, and stacking sequence. The strain behaviour of a commercially available wheel constructed using pre-tensioned steel spokes was established through the comparison of measured physical and FEA strains resulting from applied pressure, radial, lateral, torsional, and combined loads. Structural topology optimization software was then utilized to produce 48 different wheel geometries corresponding to a combined loading scenario consisting of pressure, radial, and lateral loads. The variables controlled during this process included the objective optimization function, safety factor, target design volume, split-draw constraint, and degrees of cyclic symmetry. The optimum geometry was determined by means of evaluating specific stiffness and potential towards being manufactured as a composite component. Three composite wheel FEA base models, with uni-directional laminae stacked at different fibre orientation intervals, were created according to this geometry and lightened by means of composite free size optimization. Composite sizing and shuffling optimizations were then utilized to further enhance the mass and strain characteristics of the lightest of these three solutions Two composite wheels were manufactured according to the wheel geometry, lamina shapes, and stacking sequences determined by means of structural topology and composites ptimizations. The physical mass and strain behaviour of these wheels were measured and compared to those corresponding to the optimized FEA model, as well as the commercially available wheel. This comparison showed that structural topology and composites optimization software packages can be sequentially utilized to produce an adequately stiff composite wheel of lower mass than a commercially available wheel constructed using pre-tensioned steel spokes.

- Description: Chrysomya megacephala (Fabricius, 1794) occurs on every continent and is closely associated with carrion and decaying material in human environments. Its abilities to find dead bodies and carry pathogens give it a prominence in human affairs that may involve prosecution or litigation, and therefore forensic entomologists. The identification, geographical distribution and biology of the species are reviewed to provide a background for approaches that four branches of forensic entomology (urban, stored-product, medico-criminal and environmental) might take to investigations involving this fly.

- Description: This treatise is founded in a belief that urban ecosystems should not be separate from natural ones and seeks to find ways in which existing urban systems can be reintegrated. This reintegration will be two-fold, providing a remedy for ecologically destructive urban systems as well as providing an opportunity to develop a holistic and sustainable alternative to current practices that generate waste and pollution. The treatise will focus on the management of polluted storm water, specifically along the Walmer catchment area which flows east into Airport Valley and Shark River Valley, and ways in which horticulture building systems can be utilised to achieve remedial action naturally, producing vast amounts of nutritious food for the surrounding community in the process. Impetus for this topic grew out of a concern that the author has for the current state of sustainable practices within South Africa, specifically regarding the relationship between water and agriculture (food). 60 – 70% of South Africa’s water demand is agricultural, with poor water management infrastructure and the current drought severely affecting the agricultural output (food supply) of the country. The increased demand puts immense pressure on South African farmers who have dwindling arable land and less water with which to cultivate crops. South Africa’s population is two thirds urbanised, meaning that most of the population lives in urban centres around the country. This treatise proposes that water-wise urban agricultural systems could be utilised to further cement food and water security in an urban setting by supplementing the food supply chain with local, city-grown produce. The research conducted will generate an architectural and urban intervention that marries the natural with the built environment in a strategically and intentionally designed relationship that exploits synergies between these two environments.

- Description: In today’s dynamic market, it is crucial that logistics systems understand their activities and processes in an efficient way. Lean, in essence, is a method to assist companies in rendering efficient services to customers (Andrejic, 2013, p. 84). The Lean approach for waste elimination can be applied to many different types of operations whether in manufacturing or service industries. The identification of warehousing wastes is sometimes considered difficult in its identification within processes (Villareal, Garza, Rosas & Garcia, 2012, p. 278). The purpose of this case study is to contribute to finding a solution for the decreasing operational efficiency in the operation under study. The researcher found that this paper filled an important research gap in terms of offering management of the selected logistics institution a better understanding of the different waste types in each process. Operational areas such as receiving, unboxing, put-away, picking and issuing were examined as possible reasons for concern about service orientated wastes. The research was conducted through observations and thereafter a questionnaire was distributed amongst a sample of 40 employees within a specific logistics institution. The study discussed certain key factors in Lean, specifically focusing on the types of waste in a service environment.

- Description: Despite decades of public action by civil society, tourism education has been neglected by policy makers. This is mainly due to the fact that tourism practitioners have not yet developed strategies based on the needs of the communities. The apartheid system created an environment that continues to marginalise those living in poverty-stricken areas with no basic infrastructure. These areas are characterised by the absence of adequate tourism education, training and awareness of opportunities. In fact, tourism education is offered only at a limited number of public and private institutions even though government acknowledges that tourism education is a key element in growing the economy of a country. This study argues that there are many factors that influence the demand for international education. These are push and pull factors that motivate students to travel and study abroad. Push factors are factors that „push‟ tourists toward a particular destination and pull factors are those that „pull‟ tourists toward a destination. The former factors are the needs of the tourists and the latter determine whether or not the needs of the tourists will be met. The primary objective of the study was to obtain a better understanding of tourism and its connection to international education in an effort to attract more students and as a result cause a growth in the tourism industry. The study was based on three research objectives: The first objective was to determine what influences international students to come to Nelson Mandela Metropolitan University (NMMU) in terms of tourism attractions and activities. The second was to identify the different expectations that international students have about Port Elizabeth. The third objective was to determine the role of NMMU in attracting international students to select it as their primary host university. The main finding of the first objective is that there are push and pull factors which influence international students to come to NMMU. Students participate in individual or group activities such as entertainment, cultural activities, sporting events, sightseeing or shopping and study. Their travel is closely associated with their needs and related to the image of a destination. In terms of the second objective the main finding is that the dynamic, changing environment of Port Elizabeth influences their individual needs and aspirations. Their expectations are based on the motivation factor which stems from a need (a semester abroad and working out where it is best to do this). The decision starts with the collection of information on the various options and ends with the assessment of the traveling experience. The economic, political and technological environments all have an influence on the student needs and the decision made. The main finding in terms of the third objective is that the NMMU Office for International Education has to be creative and innovative in its marketing of the university, the city and the country in order to attract international students. In addition, NMMU must uphold and expand new competencies to continue to be a competitive study abroad destination for international students worldwide. The attractiveness of NMMU can be improved by increasing the marketing material that is being sent out to attract international students and by increasing the destination marketing strategies used by the NMMU Office for International Education.

- Description: The Ecca Group of Karoo Supergroup is a sedimentary rock sequence that deposited between the Late Carboniferous (Dwyka Group) and the Late Permian-Middle Triassic (Beaufort Group). The Ecca Group investigated in this study is situated in the Eastern Cape Province of South Africa and it comprises mainly of shales, mudstones, siltstones and sandstones. The Ecca Group sequence contains considerable carbon content and suitable thickness to make it an ideal target for shale gas exploration. Previous studies put more emphasis on the geology and stratigraphy of the Ecca Group, this study revised the stratigraphy, and put new insight on the petrography, depositional processes, sedimentary facies, provenance, paleoweathering, tectonic setting, subsidence rates and history, electrical resistivity, source rock characteristics and diagenesis of the potentially feasible sandstone and mudrock reservoir rocks of the Ecca Group. Based on the lithological features, sedimentary structures and facies characteristics, the stratigraphy of the Prince Albert, Whitehill, Collingham and Fort Brown Formations of the Ecca Group is now subdivided into two informal members each, i.e. Lower Member and Upper Member. Furthermore, the Ripon Formation is now subdivided into three informal members. Each member has been asigned a lithological name. The grain size parameters show that most of the Ecca Group sandstones are very fine to fine grained, poorly to moderately well sorted, mostly near-symmetrical and mesokurtic in grain-size distribution. The linear discriminant function analysis is dominantly indicative of turbidity current deposits under deep marine environment for Prince Albert, Whitehill and Collingham Formations, shallow marine environment for Ripon Formation, while the Fort Brown Formation is lacustrine-deltaic deposits. Modal composition analysis and petrography studies revealed that the detrital components of the sandstones are dominated by monocrystalline quartz, feldspar and lithic fragments. The sandstones are compositionally and texturally immature and can be classified as feldspathic wacke and lithic wacke. The provenance analysis revealed plutonic and metamorphic terrains as the main source rocks with minor debris derived from recycled sedimentary rocks. The detrital modal compositions of these sandstones are related to back arc to island and continental margin of tectonic setting. Based on the detailed sedimentological analyses of outcrop and borehole data, fourteen lithofacies were identified and seven facies associations (FAs) were recognised. The facies associations are: FA 1: Shale and mudstones intercalated with siltstones, FA 2: Carbonaceous shale, mudstone with subordinate chert and sandstone, FA 3: Mudstones rhythmite with thin bedded mudstone and lenticular siltstone, FA 4: Greyish medium bedded sandstone intercalated with laminated mudstone, FA 5: Dark-grey medium to thick bedded mudstone and siltstone, FA 6: Thin to medium bedded sandstone alternated with thin bedded carbonaceous mudstone, and FA 7: Varved mudstone rhythmite intercalated with siltstone and minor sandstone. Sedimentological characteristics of the identified facies associations indicate four deposition environments, namely, deep marine basin, turbidite, shallow marine and lacustrine environments, which constitute a gradually regression sequence as a result of sea-level dropping and shallowing of the basin during the developmental processes. Geochemical analysis of the Ecca mudrocks and sandstones revealed that the rocks are of quartzose sedimentary provenance, suggesting that they were derived from a cratonic interior or recycled orogen. The petrography and geochemistry of the sandstones indicated that the source areas are composed of plutonic and metamorphic rocks with a minor component from sedimentary rocks. The geochemical diagrams and indices of weathering suggested that the granitic source rocks underwent moderate to high degree of chemical weathering. The tectonic setting discrimination diagrams support passive continental margin setting of the provenance.

- Description: This study was aimed at better understanding the function of protected areas as a management strategy for the Chobe District fishery in Botswana, by first investigating the relative abundance in fish communities in and outside protected areas and secondly, by performing an assessment of the biology of commercially important large cichlid species viz threespot tilapia Oreochromis andersonii, greenhead tilapia Oreochromis macrochir and redbreast tilapia Coptodon rendalli. In this study, data and specimens were collected during seasonal surveys between September 2014 and April 2015, using the standard graded fleets of gillnets employed in other programmes in the region, together with D-nets, angling and electro-fishing. The study demonstrated that fish communities in the floodplain ecosystems in the Chobe District of Botswana were representative of the region, containing some 70 species in 14 families. This study also demonstrated that for all the species collected, the mean Catch Per Unit Effort (CPUE) by weight for all the species was significantly higher in protected areas (Kruskal Wallis Test; P<0.05) namely, Zibadianja Lagoon (38 ± 31 kg/net.night"1 and Savuti River/marsh 25 ± 19 kg/net.night"1) than in the fished Chobe River floodplains CPUE (6 ± 3 kg/net.night-1). Biological contributions were estimates of longevity, growth and maturity for O. andersonii, O. macrochir and C. rendalli. Age and growth were estimated using sectioned sagittal otoliths. The Von Bertalanffy growth equation from otolith derived length at age was Lt(mm) =298 (1-e-0 59(t=- 098)) for O. andersonii and Lt(mm) = 337 (1-e-0'20(t=-235)) for C. rendalli. The results indicated that protected areas enhanced fish longevity, and fish in protected areas were larger and older than those in exploited areas. Maturity estimates for the large cichlids were consistent with other research in the region and the length-at-50% maturity was estimated as 250mm Lt for O. andersonii, 225 mm Lt for O. macrochir and 210 mm Lt for C. rendalli. Management recommendations are therefore to retain gill net mesh size regulations that ensure that these fish reach maturity and can breed before being harvested and to assess the possibility of increasing the number of protected areas in the district.

- Description: This study set out to examine transformative social learning and sustainability in the context of community-based irrigation systems in Mozambique. These irrigation systems are socio-ecological in nature. The history of irrigation systems in Mozambique can be described in two periods: pre-Independence period (mainly the colonial period) and the post-Independence period from 1975 onwards. Most recently, the Mozambique Government has introduced a policy which supports community-based irrigation system implementation and management via irrigation associations in a move to support a shift from rain-fed farming practices to irrigation-supported farming practices amongst smallholder farmers. It is this shift in the object of activity that this study focusses on. It does this by studying learning process in the constituted irrigation associations, examining whether such learning is transformative and sustainability oriented or not, and how such learning can be further expanded and supported. Learning may occur in socio-ecological systems, but whether that learning enables transformation and sustainability of irrigation systems and the constituted associations is as yet under-explored in the Mozambique context and in the context of Education for Sustainable Development in southern Africa. The aim of this research was therefore to understand transformative social learning within the development of sustainable irrigation practices in the context of irrigation associations and new agrarian policy development in Mozambique. To examine transformative social learning in sustainable irrigation system practices (including management practices), the study worked with three research goals, which also formed phases of the study’s design: GOAL 1: Examine how and what transformative social learning has (or has not) emerged in existing activity systems to date (Phase 1: Activity System Analysis). GOAL 2: Examine how transformative social learning could emerge through expansive learning processes (Phase 2: Identification of contradictions and new solution modelling through Developmental Work Research and Change Laboratories). GOAL 3: Identify what opportunities exist for ongoing transformative social learning (Phase 3: Identification of absences and ongoing dialectical transformation possibilities). The study draws on theories of Social Learning, Transformative Learning and Cultural Historical Activity Theory’s (CHAT) expansive learning and formative interventionist research framework to develop insights into the learning processes. It works especially with third generation Cultural Historical Activity Theory which provides a theory of expansive social learning and collective transformative agency formation, which I deemed most appropriate for the need to understand the transformation of farmers’ activities in a collective formation such as an irrigation association. The study involved identification and examination of interacting activity systems, contradictions or dissonances in two case studies of community-based irrigation system development via the respective associations. It involved identifying existing learning, as well as engaging in formative intervention research to expand learning in two case study sites: namely the Macubulane and Massaca Irrigation Associations, located near Maputo, Mozambique in the Inkomati and Umbeluzi river basins. The Macubulane community practices a monocropping system of sugar cane plantations using sprinkler irrigation methods and the Massaca community practices a mixed cropping system growing vegetables using mainly gravity or furrow irrigation methods. The study uses a qualitative research approach and is underlaboured by Dialectical Critical Realism which allowed for a deeper probing of ontology and transformative praxis, and transformative learning. The study used methods which included in-depth interviews, change laboratory workshops, document analysis and focus group interviews with farmers and subjects in associated activity systems. Analysis involved activity system analysis, identification of contradictions, modeling of solutions, transformative agency analysis, as well as analysis of real and nominal absences and generative mechanisms as recommended in dialectical critical realism. I used inductive, abductive and retroductive modes of inference, relying on the latter to identify further potential for transformative learning. The study demonstrates that within the associations, transformative social learning is taking place as farmers seek to address problems and contradictions. This learning leads to the creation of new agency and capabilities by ensuring good yields and continuous improvement of management practices and social status. Learning operates through formal mediation in the irrigation system of workplace-based operation, maintenance and crop management practices (i.e. through workplace learning). Social learning occurs through collective engagement with the constraints that the association faces while applying new knowledge, introducing new technology, in the process of administration and planning of irrigation activities. Expansive learning is possible when mediated actively through formative interventions in change laboratory workshops. All three types of learning were found to be present and possible in the context of the two irrigation scheme contexts. The main study findings are that transformative social learning is a collective object-driven process in the context of a transforming object (from rain-fed to sustainable community-based irrigation scheme farming in this study), that can be explained from the level of generative mechanisms and associated real absences that shape nominal absences and contradictions within and between activity systems. These induce, and have potential to induce, transformative learning in irrigation systems, including the emergence of transformative agency via learning through workplace-based, wider social learning, and expansive learning interaction processes amongst subjects in interacting activity systems. Absenting absences is also crucial for extending the potential of transformative learning in irrigation associations. The study further shows how critical realism helps to interpret learning processes and how it strengthens the empirical findings obtained from qualitative analysis. A key outcome of the study is a model that frames conceptualisation of transformative social learning in irrigation systems. The model and the insights gained into farmers learning around the transformation of the object of activity explored in this study have implications for wider curriculum and policy development interventions. The study therefore also makes recommendations for curriculum development and policy implementation intervention.

The study contributes towards understanding of sustainability learning in irrigation associations in terms of concepts and practices. The study offers a model for transformative social learning in irrigation scheme development and suggests an expanded curriculum for community-based irrigation association practice and management.

- Description: This study set out to examine transformative social learning and sustainability in the context of community-based irrigation systems in Mozambique. These irrigation systems are socio-ecological in nature. The history of irrigation systems in Mozambique can be described in two periods: pre-Independence period (mainly the colonial period) and the post-Independence period from 1975 onwards. Most recently, the Mozambique Government has introduced a policy which supports community-based irrigation system implementation and management via irrigation associations in a move to support a shift from rain-fed farming practices to irrigation-supported farming practices amongst smallholder farmers. It is this shift in the object of activity that this study focusses on. It does this by studying learning process in the constituted irrigation associations, examining whether such learning is transformative and sustainability oriented or not, and how such learning can be further expanded and supported. Learning may occur in socio-ecological systems, but whether that learning enables transformation and sustainability of irrigation systems and the constituted associations is as yet under-explored in the Mozambique context and in the context of Education for Sustainable Development in southern Africa. The aim of this research was therefore to understand transformative social learning within the development of sustainable irrigation practices in the context of irrigation associations and new agrarian policy development in Mozambique. To examine transformative social learning in sustainable irrigation system practices (including management practices), the study worked with three research goals, which also formed phases of the study’s design: GOAL 1: Examine how and what transformative social learning has (or has not) emerged in existing activity systems to date (Phase 1: Activity System Analysis). GOAL 2: Examine how transformative social learning could emerge through expansive learning processes (Phase 2: Identification of contradictions and new solution modelling through Developmental Work Research and Change Laboratories). GOAL 3: Identify what opportunities exist for ongoing transformative social learning (Phase 3: Identification of absences and ongoing dialectical transformation possibilities). The study draws on theories of Social Learning, Transformative Learning and Cultural Historical Activity Theory’s (CHAT) expansive learning and formative interventionist research framework to develop insights into the learning processes. It works especially with third generation Cultural Historical Activity Theory which provides a theory of expansive social learning and collective transformative agency formation, which I deemed most appropriate for the need to understand the transformation of farmers’ activities in a collective formation such as an irrigation association. The study involved identification and examination of interacting activity systems, contradictions or dissonances in two case studies of community-based irrigation system development via the respective associations. It involved identifying existing learning, as well as engaging in formative intervention research to expand learning in two case study sites: namely the Macubulane and Massaca Irrigation Associations, located near Maputo, Mozambique in the Inkomati and Umbeluzi river basins. The Macubulane community practices a monocropping system of sugar cane plantations using sprinkler irrigation methods and the Massaca community practices a mixed cropping system growing vegetables using mainly gravity or furrow irrigation methods. The study uses a qualitative research approach and is underlaboured by Dialectical Critical Realism which allowed for a deeper probing of ontology and transformative praxis, and transformative learning. The study used methods which included in-depth interviews, change laboratory workshops, document analysis and focus group interviews with farmers and subjects in associated activity systems. Analysis involved activity system analysis, identification of contradictions, modeling of solutions, transformative agency analysis, as well as analysis of real and nominal absences and generative mechanisms as recommended in dialectical critical realism. I used inductive, abductive and retroductive modes of inference, relying on the latter to identify further potential for transformative learning. The study demonstrates that within the associations, transformative social learning is taking place as farmers seek to address problems and contradictions. This learning leads to the creation of new agency and capabilities by ensuring good yields and continuous improvement of management practices and social status. Learning operates through formal mediation in the irrigation system of workplace-based operation, maintenance and crop management practices (i.e. through workplace learning). Social learning occurs through collective engagement with the constraints that the association faces while applying new knowledge, introducing new technology, in the process of administration and planning of irrigation activities. Expansive learning is possible when mediated actively through formative interventions in change laboratory workshops. All three types of learning were found to be present and possible in the context of the two irrigation scheme contexts. The main study findings are that transformative social learning is a collective object-driven process in the context of a transforming object (from rain-fed to sustainable community-based irrigation scheme farming in this study), that can be explained from the level of generative mechanisms and associated real absences that shape nominal absences and contradictions within and between activity systems. These induce, and have potential to induce, transformative learning in irrigation systems, including the emergence of transformative agency via learning through workplace-based, wider social learning, and expansive learning interaction processes amongst subjects in interacting activity systems. Absenting absences is also crucial for extending the potential of transformative learning in irrigation associations. The study further shows how critical realism helps to interpret learning processes and how it strengthens the empirical findings obtained from qualitative analysis. A key outcome of the study is a model that frames conceptualisation of transformative social learning in irrigation systems. The model and the insights gained into farmers learning around the transformation of the object of activity explored in this study have implications for wider curriculum and policy development interventions. The study therefore also makes recommendations for curriculum development and policy implementation intervention. The curriculum development recommendations are not at the level of making recommendations for new courses only, but frame how the design of new courses should take into account the wider processes of learning and change associated with the transformation of an object of activity as articulated in the study. It recommends an approach that allows for in-field engagement with contradictions and the absenting of absences (a problem-based type of curriculum) that will also allow for conceptual development and understanding of the changing object of activity (i.e. community-based irrigation scheme practice and management). The main policy recommendation made from the study is to invest more in farmer support and farmers’ learning so that they can transition from rain-fed agriculture to sustainable irrigation scheme development and management via their associations. The research contributes to knowledge production on irrigation practices; considering that substantial understandings were generated through analysis of communal irrigation scheme practice and management and its implications, especially from a transformative learning perspective.

- Description: South Africa, with its establishment of the National Department of Small Business Development, in 2014, made its intentions known for wanting to create a conducive environment by developing and supporting small businesses and cooperatives through financial and non-financial provisions. Nevertheless, there is still a high failure rate of Small, Medium and Micro-sized Enterprises (SMMEs), many of them failing on their first year due to various challenges and circumstances, one of which is lack of access to finances. Banks have been and still are unwilling to provide SMMEs with loans due to SMMEs’ having high-risk levels of failure rates. This gap gives an opportunity to micro-finance institutions (MFIs) to provide financial support to the SMMEs, which comes with the challenge of properly screening the SMMEs and the possible risk of non-payment. The big question is whether MFIs are willing to support SMMEs and whether SMMEs are interested in obtaining support from MFIs. If so, what are the roles, functions and influence of MFIs towards the SMMEs? This study was undertaken to examine the impact and effectiveness of microfinance institutions (MFIs) in discharging their duties and responsibilities towards SMMEs in South Africa, by first considering the nature, challenges and scope of SMMEs as well as the nature and extent, risks, credit ratings, impact assessment and regulations that affect the products and services of MFIs. Both quantitative and qualitative research methodologies were used in this study. It was found that most SMMEs are making use of the products and services of MFIs. MFIs have been found to provide different reasons for supporting SMMEs, which were also measured and assessed against the previous study, and similar trends were found.The study further found the following: 65% of SMMEs needed microfinance assistance/support from MFIs, 54% of SMMEs were satisfied with the services rendered by MFIs, 35% of MFIs reached out to SMMEs, and 67% of SMMEs preferred formal and registered MFIs for financing of their business activities. The types of risks that most MFIs are faced with were found to be loan repayments from SMMEs, providing smaller loans in order to cater for multiple clients, client dropouts, financial regression, switching of clients, clients engaged with multiple competing MFIs, and making use of informal and unregistered MFIs. Natural disasters such as floods was found to be the least type of a risk. Most SMMEs (approximately 82%) have alluded to the use of informal and unregistered MFIs, due to the convenience of getting support, where there is no screening of the applications, in spite of higher loan interest rates. About 61% of MFIs happen to have a formal screening process of the loan application, which comprises mainly credit checks. No thorough vetting process is done on the clients. Some MFIs (approximately 39%) do not have criteria for assessing whether to fund or not to fund microenterprises, and this is a huge risk, as these MFIs are exposing themselves to non-repayment vulnerabilities by the SMMEs. About 63% of the MFIs were not aware of most of the rules and regulations that affect MFIs, which gives an indication that there is a lack of awareness, education and training.

- Description: This study assessed the public participation strategies from the perspective of local government governance in encouraging community participation with specific reference to the Nyandeni Local Municipality (NLM). The research was based on the assumption that one of the biggest challenges facing most municipalities in South Africa is the lack of effective public participation strategies which results in service delivery protest actions. As a local municipality, the NLM has been entrusted with the responsibility to promote and encourage community participation.. . The purpose of the research study was to investigate and observe the public participation strategies with specific reference to the Nyandeni Local Municipality. The assessment of the public participation strategies of the NLM will therefore be fundamentally descriptive, but highly exploratory in nature. This research employed the quantitative method. An empirical survey was employed for purposes of the study and the research findings are described, interpreted, and analysed. Data was collected by way of a suitably constructed questionnaire which was administered to the ward committee members. The research has established that there is a good public participation approach in place but its functioning is inadequate, the ward committee members have little understanding of their roles and responsibilities in terms of the implementation of the public participation strategy, and they have failed to facilitate communication between the Municipality and the community. There was also an indication that the service delivery protest actions were fuelled by political motives and certain challenges and not solely by a lack of an effective public participation. In addition, the language used by the Municipality is mostly not understandable to the community as a whole. This research also identifies the strengths and the weaknesses of the public participation strategies as these are regarded as critical in promoting successful local democracy. It is envisaged that this research will assist the Nyandeni Municipality, and other municipalities country-wide to identify challenges with which they are faced and to deal with these accordingly in terms of the objectives identified in the public participation strategies. Furthermore, this research study envisages promoting effective public participation strategies within the Nyandeni Local Municipality as well as improving the efficiency and effectiveness of service delivery that will ensure communities of their well-being and dignity. Various recommendations are presented, based on the findings, primarily from the literature review and empirical survey, on how the existing status quo of the NLM can be changed to enhance public participation. If these recommendations are adopted, the Nyandeni LM will be able to develop and implement effective public participation strategies.

- Description: Vibratory motion is fundamental to all natural phenomena. It occurs everywhere in nature, from fundamental particles to the complexity of the life of the smallest cell, to the properties of the cosmos. Its frequency ranges from those of gammarays down the spectrum of X-rays, microwave, optical and radio waves. These are common concepts in everyday life, but their origin and nature are seldom comprehended. In this thesis we look at the mathematical fundamentals and how to apply them. We start with fundamental concepts and extend them to more complicated systems. We consider methods of analysis and applications. In Chapter 2 we consider simple harmonic oscillators and their mathematical analyses and in Chapter 3 we look at applications. Chapter 4 discusses the general form of simple harmonic motion, i.e. damped and forced harmonic motion. We consider simple coupled systems and their analysis. In Chapter 5 we introduce the method of complex functions and its application to complicated compound systems. Chapter 6 introduces a novel application, that of how SHM can be used as a model for advanced effects, or acausality. Chapter 7 presents a summary and conclusion.

- Description: Reintroduction is a potentially powerful tool available to conservationists to cope with species population declines. Nonetheless, it is poorly understood and past reviews tend to indicate poor results. Reintroduction, under the sensu stricto IUCN definition, must have a primary objective of conservation; however species can be released to sites in their indigenous range (reintroduction sensu lato) to meet other objectives. The outcomes of these reintroductions s.l need to be assessed to determine how effectively they achieve their varied objectives. A Web of Science review revealed that only 32.1% of 131 publications on reintroduction provided clearly defined success criteria. Using economic, ecological, conservation and problem animal management objectives as reintroduction s.l. drivers, I developed context-dependent success definitions for each objective to use in reintroduction outcome assessments. These success criteria were then used to assess the reintroductions s.l. of large carnivores, namely lion, leopard, cheetah, African wild dog, spotted hyaena, and brown hyaena, to 16 private- and state-owned reserves in the Eastern Cape Province, South Africa. Ecotourism and ecological restoration were the most common objectives for the reintroduction of top predators to these reserves. Overall the reintroductions of large carnivores have been successful in meeting their objectives. Only African wild dogs have failed to establish in the province. Causes of objective-specific failures for the other species in some reserves included introductions of same-sex populations, lack of breeding events and changes in reserve management objectives. Assessments for leopard and brown hyaena were inconclusive due to lack of monitoring data. The reintroduction of large carnivores to the Eastern Cape Province has also resulted in the emergence of human-carnivore conflict on neighbouring properties. Carnivores have reportedly escaped from 8 reserves (61.5% of reserves) in the Eastern Cape. A total of 75 conflict events on 68 neighbouring properties (36.7% of neighbouring properties) have been reported. There is a major gap in research around conflict resulting from carnivore reintroductions and future research is required to fully understand the situation in the province in order to develop effective mitigation methods. An adaptive management approach to reintroductions is encouraged to improve monitoring and ensure reintroductions continue to meet their objectives. Furthermore, emerging consequences, such as human-wildlife conflict, and related mitigation strategies should be incorporated into management of reintroduced populations. Communities surrounding reintroduction sites should be educated on lifting baselines where conflict-causing species are recovering to ensure continued success of reintroduction undertakings. National management plans should be developed for all large carnivore species to improve the conservation value of small, fenced reserves that are typical of South African conservation, through a managed metapopulation approach. Management plans should include social, political, and economic factors that can influence the success of reintroductions and ultimate conservation outcomes.

- Description: Disasters are inevitable events that impact negatively on humanity in South Africa and globally. Though disasters are global the most at risk populations are predominantly from developing countries and particularly poor communities experience multi-layered threats from floods, droughts, poor energy supply, inter alia. However, the urban communities have not been spared the effects of these disasters and have cause of concern. Millions of people have suffered and passed on because of disasters. These disasters cannot be prevented in certain environments but mechanisms can be put in place by the relevant officials such as government institutions or relevant stakeholders to help mitigate and reduce the effects of these disasters and further contribute to sustainable development. The Disaster Management Act in South Africa provides clear mandates, through policy and guidelines, on how to identify and reduce risk to disasters and how to prepare and respond to emergencies and disasters, structures and mechanisms, as well as the necessary systems. The local authorities such as the Disaster Management Department‘s roles and responsibility have been clearly stipulated and emphasised. It is therefore the mandate of the department to ensure that each and every community receives the adequate services that are entitled to them to help reduce the effects of the natural disasters and in turn contribute to the promotion of sustainable development. The overall aim of the Case Study in Redhouse was to investigate the effectiveness of the NMBM Disaster Management Department in urban sustainability. The research made use of the qualitative research methodology and followed the inductive approach. This was supported by a survey which was administered to willing participants chosen at random whose extensive experience is relevant to this research topic. Interviews involved direct personal contact with participants who were asked to respond to questions relating to the research study. The research sample consisted of a total number of eight participants. The Disaster Management Official was represented by two participants: the Redhouse community, which was represented by five participants, and the local NGO, which was represented by 1 participant. Current knowledge on the topic has been analysed and new knowledge with recommendations, has been generated through findings from this study.

The research made use of the qualitative research methodology and followed the inductive approach. This was supported by a survey which was administered to willing participants chosen at random whose extensive experience is relevant to this research topic. Interviews involved direct personal contact with participants who were asked to respond to questions relating to the research study. The research sample consisted of a total number of eight participants. The Disaster Management Official was represented by two participants: the Redhouse community, which was represented by five participants, and the local NGO, which was represented by 1 participant. Current knowledge on the topic has been analysed and new knowledge with recommendations, has been generated through findings from this study.

- Description: Countries should encourage their workforce to foster human development as it contributes to the economic development through having a well-trained and skilled workforce. The countries that are economically developed have stood out because of human capabilities that have triggered economic development. With innovation being one of the major advantages of human capital, new ideas lead to the creation of vast employment opportunities especially for those that have studied critical skill subjects. The economic status of Zimbabwe shows that there is human capital development happening in the country, but there is a serious shortage of skills in sciences, technology, engineering and mathematics that are necessary for the industrialisation of the country. The government believes that Zimbabwe can industrialise if STEM education is integrated in the country’s educational system to make human capital development wholistic. The study aims to understand the concept of human capital development and how it can be developed at a balance. A discussion on the primary role of universities and higher learning institutions on developing human capital will be done. Universities educate and equip students with knowledge and skills, hence both STEM and non-STEM curricula is needed to develop human capital that is balanced. This is because STEM graduates that are innovative can create jobs for non-STEM graduates and help a country to industrialise and develop its economy. Universities are recommended to increase public awareness of STEM, train teachers specifically for STEM, invest in research and development and develop STEM-related policies and systems to develop more STEM graduates to strike a balance with non-STEM graduates and enhance industrialisation in Zimbabwe. Interviews were conducted and analysed and some of the recommendations made were to encourage the government to deregulate to attract investment, to increase the public’s awareness of STEM and to train STEM teachers accordingly.
