- Description: The study explored the potential of Geography fieldwork projects to develop learners’ action competence in response to social-ecological problems in two schools in the Omusati and Oshana Education Regions. The study investigates ways in which learners’ activities create an opportunity for them to act for the environment. That is, to investigate ways in which learners can be shaped into environmentally literate citizens who act for the environment. A total of 43 grade 10 learners and two grade 10 Geography teachers participated in this qualitative, interpretive case study. Data was generated through document analysis, focus group interview with learners, semi-structured interviews with educators, and participant observations. Such data were analysed into three phases, first inductively and then abductively using Jensen’s (2004) Investigations, Visions, Actions and Change (IVAC) model to produce analytic statements that form the basis of the research findings. The study found that Geography fieldwork projects foster understandings of environmental problems in a local area. Through fieldwork projects, schools initiate indirect environmental actions, however, some environmental problems are too large or complex to be resolved by the actions initiated by learners. Based on these findings, the study identifies Geography fieldwork as an opportunity to create a community of practice in effort to address socioecological concerns. The study further recommends that learners should be allowed to engage with both social investigative actions and technical, scientific investigative actions when doing project work.

- Description: The arts and cultural sector has come under even more financial strain than it previously was, as it has to compete with other sectors of the economy for the very limited public funding that is available. It is in this context that the economic impact, and the role, of the arts and cultural sector towards advancing economic growth and development, needs be examined. This thesis investigates the potential for the positive impact of the cultural and creative industries (CCIs) on growth and development of small cities and towns. Furthermore, it also provides guidelines for the development of regional cultural policy in small cities and towns. The CCIs have also been touted as a catalyst for economic growth and economic development, hence the global rise in their interest. For example, the CCIs have been used to redevelop and revive urban areas that have been rundown. CCIs, however, tend to develop in clusters, and additionally, they cluster around large cities. However, the lack of reliance of some CCIs on long supply chains or high-technology inputs may make them suitable candidates for investment in small cities and towns. Additionally, the link that small cities and towns have with rural and isolated areas makes them potential engines for driving growth, development, as well as employment creation for these areas, given their decline as a result of the transition from the traditional agricultural economy, to the knowledge economy. As CCIs have the propensity to drive government’s macroeconomic objectives such as efficiency, equity, economic growth and job creation, it is necessary to develop cultural policy that regards this. The tendency of CCIs to cluster and develop around large cities inevitably means that very little research into cultural policy directed towards regions without large cities and towns has been done. By the same token, very little research has also been conducted on how to craft cultural policy for such areas. In order then, for cultural policy for regions without large cities and towns to be developed, it is necessary to investigate, and provide, guidelines on, how to develop cultural policy for such regions. As a case study, the Sarah Baartman District Municipality (SBDM) in the Eastern Cape was chosen. The SBDM has no large cities and towns, but the District Municipality has identified the CCIs as a potential growth sector, and is in the process of developing a regional cultural policy. The area also includes Grahamstown, which not only hosts the National Arts Festival, which is the largest arts event of its type in Africa, but is also piloting the “Creative City” project in South Africa. An audit and mapping study was conducted on the CCIs in the SBDM; this was based on a national mapping study commissioned by the Department of Arts and Culture. Further internet searches, as well as consultations with the provincial and regional Department of Arts of Culture, coupled with snowball sampling, also aided in the identification of CCIs, and consequently, the “creative hotspots” within the SBDM. Two random samples of stakeholders were chosen; the CCI owners and practitioners, as well as key stakeholders such as government officials, and interviews conducted with both groups, in order to get a first-hand perspective on the operations, activities, challenges, and opportunities that are faced by the CCIs. The study found that there were at least 441 CCIs in the SBDM, with two local municipalities (Dr. Beyers Naude and Makana) hosting the largest share of these (145 and 113 CCIs in each local municipality respectively), which indicates some support for the ‘clustering’ theory. It was also found that the local municipalities that had the largest number of CCIs also experienced better socio-economic welfare. Furthermore, based on the UNESCO Framework for Cultural Statistics (FCS) domains, the Visual Arts and Crafts; Information, Books and Press; and, Cultural Heritage domains were the largest domains represented in the SBDM. It was concluded that cultural policy that is developed, ought to take advantage of, and build on, these existing clusters, as well as the domains that are most prevalent in the region. To demonstrate the impact of cultural festivals on growth and development, a socio-economic impact study was undertaken at the 2016 National Arts Festival (NAF) in Grahamstown. Face to interviews, as well as self-completion questionnaires were used, with respondents at different venues, attending a variety of shows, and across a range of demographics, being interviewed, in order to get a representative sample of Festival attendees. It was found that the economic impact of the 2016 NAF on the city of Grahamstown was R94.4 million. Over and above the economic value of the NAF, it was also found that there were nonmarket benefits (social and intrinsic values) of the NAF, that included audience development, education of the arts and culture, social cohesion, and community development. The inability to directly track and measure social and intrinsic values proved to be a challenge. The study concluded that in order for successful cultural policy to be developed in regions without large cities and towns, it is first necessary to carry out a study to identify what resources are present, and where they are. Locating resources enables cluster identification - as clusters encourage comparative and competitive advantage, it is worthwhile to invest in areas where there are clusters. Therefore, in the allocation of scarce public funds, cultural policy needs to guide investment in to areas where established clusters indicate existing comparative advantage. In terms of equity and transformation, it is also necessary to evaluate labour markets and ownership patterns when developing cultural policy. Beyond the analysis of physical and human resources, the study also found that a crucial step towards developing successful cultural policy is identification of opportunities and challenges faced by the practitioners themselves; the policy ought to capitalise on the opportunities, whilst attempting to correct the challenges faced. Also of importance is aligning the proposed policy and its objectives with regional, provincial and national aims and objectives. Finally, it is important to include a monitoring and evaluation tool that will evaluate the performance of the policy against its stated aims and objectives.

- Description: In spite of the fact that the African ionospheric equatorial region has the largest ground footprint along the geomagnetic equator, it has not been well studied due to the absence of adequate ground-based instruments. This thesis presents research on both tomographic imaging of the African equatorial ionosphere and the study of the ionospheric irregularities/equatorial plasma bubbles (EPBs) under varying geomagnetic conditions. The Multi-Instrument Data Analysis System (MIDAS), an inversion algorithm, was investigated for its validity and ability as a tool to reconstruct multi-scaled ionospheric structures for different geomagnetic conditions. This was done for the narrow East African longitude sector with data from the available ground Global Positioning Sys-tem (GPS) receivers. The MIDAS results were compared to the results of two models, namely the IRI and GIM. MIDAS results compared more favourably with the observation vertical total electron content (VTEC), with a computed maximum correlation coefficient (r) of 0.99 and minimum root-mean-square error (RMSE) of 2.91 TECU, than did the results of the IRI-2012 and GIM models with maximum r of 0.93 and 0.99, and minimum RMSE of 13.03 TECU and 6.52 TECU, respectively, over all the test stations and validation days. The ability of MIDAS to reconstruct storm-time TEC was also compared with the results produced by the use of a Artificial Neural Net-work (ANN) for the African low- and mid-latitude regions. In terms of latitude, on average,MIDAS performed 13.44 % better than ANN in the African mid-latitudes, while MIDAS under performed in low-latitudes. This thesis also reports on the effects of moderate geomagnetic conditions on the evolution of EPBs and/or ionospheric irregularities during their season of occurrence using data from (or measurements by) space- and ground-based instruments for the east African equatorial sector. The study showed that the strength of daytime equatorial electrojet (EEJ), the steepness of the TEC peak-to-trough gradient and/or the meridional/transequatorial thermospheric winds sometimes have collective/interwoven effects, while at other times one mechanism dominates. In summary, this research offered tomographic results that outperform the results of the commonly used (“standard”) global models (i.e. IRI and GIM) for a longitude sector of importance to space weather, which has not been adequately studied due to a lack of sufficient instrumentation.

- Description: The main objective of the project was to contribute to the incorporation of uncer-tainty assessments in water resource decision making in South Africa, thereby quan-tifying the risks associated with specific decisions about planned future water re-source developments. This objective was supported by several specific aims: 1. De-velop an understanding of uncertainty and associated risks in water resource man-agement on the basis of literature and known practices, nationally and internation-ally. 2. Identify and characterise the main sources of uncertainty (focusing on cur-rent South African practice and typical situations of data availability). 3. Develop techniques and guidelines for quantifying the uncertainty associated with different models. This will include uncertainty in all relevant areas (hydrological, climate, economic, social, etc.). 4. Determine the effects of uncertainty on water resource management and identify what level of uncertainty is acceptable. 5. Develop guide-lines for the communication of uncertainty and the impacts to various stakeholder groups involved within water resource planning and management. This aim will need to address the issue of the links between uncertainty and risk. 6. Develop guidelines for incorporating uncertainty and the associated risk into water resource decision making processes. 7. Identify those areas of uncertainty that can be realistically re-duced and which will have the greatest impact on reducing the risks involved with water resource decision making.
