- Description: Because the Anthropocene by definition is an epoch during which environmental change is largely anthropogenic and driven by social, economic, psychological and political forces, environmental social scientists can effectively analyse human behaviour and knowledge systems in this context. In this subject review, we summarize key ways in which the environmental social sciences can better inform fisheries management policy and practice and marine conservation in the Anthropocene. We argue that environmental social scientists are particularly well positioned to synergize research to fill the gaps between: (1) local behaviours/needs/worldviews and marine resource management and biological conservation concerns; and (2) large-scale drivers of planetary environmental change (globalization, affluence, technological change, etc.) and local cognitive, socioeconomic, cultural and historical processes that shape human behaviour in the marine environment. To illustrate this, we synthesize the roles of various environmental social science disciplines in better understanding the interaction between humans and tropical marine ecosystems in developing nations where issues arising from human–coastal interactions are particularly pronounced. We focus on: (1) the application of the environmental social sciences in marine resource management and conservation; (2) the development of ‘new’ socially equitable marine conservation; (3) repopulating the seascape; (4) incorporating multi-scale dynamics of marine social–ecological systems; and (5) envisioning the future of marine resource management and conservation for producing policies and projects for comprehensive and successful resource management and conservation in the Anthropocene.

- Description: A key economic issue for government is the ability to effectively match electricity supply to electricity demand, because of the substantial economic losses in the case of where there is too little supply, or the waste of scarce resources where there is too much supply. In the case of South Africa, this issue, the importance of which was highlighted by the power shortages and associated “rolling blackouts” experience in 2008, has led to the creation of the Integrated Resource Plan (IRP) as a means to decide how energy policy will be developed. Recently, however, the IRP 2010 and its subsequent 2013 and 2016 (draft) updates have been criticised as being too optimistic in regards to their projections of economic growth and electricity demand, making the recommendations in these documents to be flawed. Using monthly data from January 1990 to May 2017, together with Autoregressive Distributed Lag (ARDL) bounds testing for cointegration, this paper measures changes in the elasticity of electricity demand as a result of the massive price hikes over the past decade. Thereafter, the implications of changed electricity as well as possibly lower Gross Domestic Product (GDP) growth in the future for forecasts of possible future demand for electricity are examined. From these revised forecasts, it is possible to make appropriate recommendations in regards to electricity supply policy for South Africa including what possible energy mix is needed as well as the requirements for creating new supply to meet possible future demand. It is concluded that future electricity demand is likely to be much lower than forecast in the IRP 2010 and IRP 2013 documents. The degree of uncertainty in electricity demand growth suggests that large-scale increases in supply capacity taking years to construct, such as coal or nuclear, should be avoided. Small, incremental increases in supply that are able to come on stream swiftly, such as gas, solar and wind power, are likely to be more appropriate for meeting South Africa’s future needs.

- Description: This study examined factors that influence the academic performance of Grade 12 learners in English Language (L 2) in the Oshikoto Region. The theoretical framework that underpinned and guided the present study was the Systems Theory of von Bertalanffy (1930), supplemented and complemented by the School Context Model of Bascia (2014). These helped me to understand how the school context shapes core processes of teaching and learning. The study sample consisted of four principals, eight parents, eight teachers and thirty two learners who were purposively sampled from four selected secondary schools. The study was anchored in the pragmatic paradigm and it adopted the mixed methods research approach. Data collection instruments consisted of questionnaires, semi-structured interviews and focus group discussions. Major findings were that, both Grade 12 English Language (L 2) teachers and learners lack English Language proficiency. This was due to lack of exposure to the English Language. The study also noted lack of learning materials in both school and the home. Major recommendations were that schools (principals) should expose both teachers and learners to English Language by coming up with policies that make it mandatory for teachers and learners to use English while at school. Teachers should also actively involve learners in their learning by using methods such as debates and drama. The study also recommended that the Ministry of Education, schools and parents work together to provide adequate reading materials for learners. For future research, the study recommended an in-depth qualitative study to test the findings of the present study.

- Description: Aromatic pollutants are a diverse group of chemicals which are continuously produced from industrialization, urbanization and sophistication in technological advancement. Pristine water source polluted by these chemicls makes the water unsafe for human consumption, and as well disrupts the trophic structure of the aquatic milieu. Physico-chemical treatment techniques employed so far have been accompanied by major drawbacks which have overriden the relative successes recorded, hence, greener, simpler and more efficient methods of pollutant transformation is imperative. The prospect of enzymatic treatment of pollutants has gradually been receiving growing attention in contemporary times due to the their environmental friendliness and production economic feasiblity. Laccase, a multicopper oxidase has heightened its appeal towards environmental and biotechnological applications due to its broad substrate specificity and its requirement of atmospheric molecular oxygen as a cosubstrate and the discharge of water as the byproduct. Hence, this present study was designed to evaluate the biotechnological potentials of laccases produced by some bacteria species from some aquatic biomes of the Eastern Cape Province, South Africa. The laccase-producing bacteria were isolated from selected environmental samples by selective enrichment using selective aromatic compounds as sole carbon source and subsequently, laccase-screening phenolic substrates. The laccase-producing bacteria were identified by molecular techniques as proteobacteria belonging to the following genera: Achromobacter, Bordetella, Citrobacter, Pseudomonas and Stenotrophomonas. Optimisation of laccase production in a submerged fermentation was by traditional and statistical methods, where four isolates (Hb9c; Achromobacter xylosoxidans HWN16, Hb16c; Bordetella bronchisepta HSO16, Berl11b2; Stenotrophomonas maltophilia BIJ16, Ie1c; Citrobacter freundii LLJ16) were evaluated for the fermentative production of laccase from lignocellulosic agroindustrial residues. Predictions from statistical optimisation showed that weakly acidic conditions (pH 5) and low agitation speed (100 rpm) were required for maximum laccase production from mandarin peelings (0.5 g/200 mL) and NaNO3 (0.25 g/200 mL) in Hb9c, maize stover (0.50 g/200 mL) and NaNO3 (0.050 g/200mL) in Berl11b2 while a lower agitation speed (50 rpm) was required for maximum laccase output from 2.0 g/200 mL maize stover and 0.050 g/200 mL KNO3 in Ie1c. However, 2.50 g/200 mL wheat bran, 0.050 g/200 mL yeast extract and 50 rpm agitiation under acidic conditions (pH3) yielded maximum laccase titres in Hb16c. Further characterisation of Hb9c and Ie1c laccase secretions portrayed their polyextremotolerant capacities. They were active at a broad range of tempertaure (0-90 degreesC); with optima at 70°C (Hb9c) and 60°C (Ie1c), pH (3-11); with optima at pH 6 (Ie1c) and pH 8 (Hb9c), respectively, and were equally thermo- and pH-stable. Their activities were either improved or left unabated by high concentrations of cations, detergents, and chloride. In addition, catalytic activities of Hb9c and Ie1c laccase secretions increased when they were preincubated with 2 – 20 percent of fluoride, a potent inhibitor. Consequently, a molecular perspective depicted the isolates to have multiple homologous laccase encoding genes. The enzymes were successfully immobilised on solid supports comprising gelatin and Na-alginate with a recovery of cca. 85 percent residual activity after 8 cycles of oprertional stability experiments. The immobilised laccases were remarkable in the decolourisation of synthetic dyes, albeit, free forms also elicited satisfactory performances. Ultimately, the application of free laccases in denim bleaching, individually or with a blend of a mediator, ABTS, showed that denim colours could be bleached without the need for chemical bleaching agents. The results obtained suggest the bacteria laccases produced from lignocellulosic wastes may serve as potent degraders of phenolic pollutants in water and, may also contribute to the bioeconomy and promote greener techniques for industrial applications.

- Description: Stromatolites are among the oldest types of microbial formations. In contrast to their ancient counterparts, many modern marine stromatolites have a coarser internal structure and host a diverse eukaryotic community. Different mesofabric structures are found within stromatolite formations which may provide microhabitat opportunities for organisms. Therefore, the first aim of this study was to investigate how the microalgal (including Bacillariophyta, Chlorophyta and cyanobacteria) community contributes towards the differences observed amongst mesofabric structures in terms of depth profiles and layering at representative stromatolites forming along the Port Elizabeth coastline in South Africa. The second aim was to investigate how the invertebrate community changes between mesofabric types. This was achieved by comparing the proportional abundances of each of the major microalgal classes between the different mesofabric types and depth profiles. Additionally, the invertebrates found within samples collected were identified and counted. These were related to site and environmental characteristics using multivariate modelling. Clear variability in terms of proportional abundance was apparent between microhabitats and with depth. Coarser, more-bioturbated types had a higher bacillariophyte biomass than smoother types. Invertebrate abundance was generally higher in coarser mats. However, one of the finer, well-laminated types had surprisingly more invertebrates than expected, but only in summer. The changes in microalgal and invertebrate community distribution varied seasonally. More microalgae were found in summer and more invertebrates were found in winter. Microalgae distribution was driven by mesofabric features whereas invertebrate distribution was attributed to resource changes. The implications of this study are in terms of the role of microalgae as ecosystem engineers in driving microhabitat differences. The microhabitats provide opportunities for colonisation by invertebrates.

- Description: Biological control offers a cost effective and ecologically sustainable tool for the management of invasive alien plants. Its implementation, however, has historically been slow and poorly co-ordinated. In South Africa, as in many other countries, most aspects of biological control programmes were done by researchers, but from 1995 onwards, with the advent of the Working for Water Programme, a more inclusive approach to biological control has been adopted. In this paper, we report on the development of community-based biological control implementation programmes in South Africa, after 1995, and highlight a number of initiatives, including employing persons with disabilities at mass-rearing facilities and in particular, we outline a suite of educational and outreach programmes for the general public and for schools, which have increased capacity, education and employment in the field of weed biological control.

- Description: The research used a change management approach to analyze the restructuring of the Nelson Mandela Academic Hospital from a tertiary to a central hospital. The study was underpinned by two objectives. Firstly, to analyze the restructuring of the Nelson Mandela Academic Hospital from a tertiary to a "central" hospital using the Core Elements Framework of change management developed by Antwi and Kale (2014). Secondly, to use the knowledge gained through literature review combined with the experiences of the managers at Nelson Mandela Academic Hospital to inform future healthcare reforms in general and particularly in the restructuring of hospitals. The Core Elements Framework by Antwi and Kale (2014) identifies six fundamental change elements from both emergent and planned change management approaches. The six elements are regarded by theorists from the two different schools of thought i.e. emergent change and planned change as key for successful change. The Core Elements Framework by Antwi and Kale, (2014) demonstrates the strength of not viewing the two approaches to change management as mutually exclusive but as complementing each other when the other is falling short. The study identified the following: ■ The change was prompted by clearly identifiable external factors more than internal factors. ■ There was notable lack of organizational harmony which may have negatively impacted the change process. ■ The Private Public Partnership (PPP) funding model which was aimed at delivering the central hospital collapsed, after a study discovered that it benefited the private sector more than the public sector. ■ There was no proper consultation of major stakeholders for preparation of the change. ■ Resources in all material forms were not made available for the change to take off, this means that there was no organizational capacity to execute the change. The study draws the conclusion that lack of organizational capacity, organizational harmony and a proper consultation process for stakeholders are the main reasons why the restructuring of the Nelson Mandela Academic Hospital is not yielding the desired results. The study recommends that organizations should implement a multidimensional approach for any change initiative to be successful and that organizations must ensure the availability of the necessary resources when embarking on change.

Firstly, to analyze the restructuring of the Nelson Mandela Academic Hospital from a tertiary to a "central" hospital using the Core Elements Framework of change management developed by Antwi and Kale (2014). Secondly, to use the knowledge gained through literature review combined with the experiences of the managers at Nelson Mandela Academic Hospital to inform future healthcare reforms in general and particularly in the restructuring of hospitals. The Core Elements Framework by Antwi and Kale (2014) identifies six fundamental change elements from both emergent and planned change management approaches. The six elements are regarded by theorists from the two different schools of thought i.e. emergent change and planned change as key for successful change. The Core Elements Framework by Antwi and Kale, (2014) demonstrates the strength of not viewing the two approaches to change management as mutually exclusive but as complementing each other when the other is falling short. The study identified the following: ■ The change was prompted by clearly identifiable external factors more than internal factors. ■ There was notable lack of organizational harmony which may have negatively impacted the change process. ■ The Private Public Partnership (PPP) funding model which was aimed at delivering the central hospital collapsed, after a study discovered that it benefited the private sector more than the public sector. ■ There was no proper consultation of major stakeholders for preparation of the change. ■ Resources in all material forms were not made available for the change to take off, this means that there was no organizational capacity to execute the change. The study draws the conclusion that lack of organizational capacity, organizational harmony and a proper consultation process for stakeholders are the main reasons why the restructuring of the Nelson Mandela Academic Hospital is not yielding the desired results. The study recommends that organizations should implement a multidimensional approach for any change initiative to be successful and that organizations must ensure the availability of the necessary resources when embarking on change.

- Description: We undertake a study of the classical regime in which Planck's constant and Newton's gravitational constant are negligible, but not their ratio, the Planck mass, in hopes that this could possibly lead to testable quantum gravity (QG) effects in a classical regime. In this quest for QG phenomenology we consider modifications of the standard dispersion relation of a free particle known as deformed special relativity (DSR). We try to geometrize DSR to find the geometric origin of the spacetime and momentum space. In particular, we adopt the framework of Hamilton geometry which is set up on phase space, as the cotangent bundle of configuration space in order to derive a purely phase space formulation of DSR. This is necessary when one wants to understand potential links of DSR with modifications of quantum mechanics such as Generalised Uncertainty Principles. It is subsequently observed that space-time and momentum space emerge naturally as curved and intertwined spaces. In conclusion we mention examples and applications of this framework as well as potential future developments.

- Description: The fabrication and application of graphene quantum dots (GQDs)-based photoluminescent probes for the detection of analytes is presented. GQDs were functionalized with complexes such as metallophthalocyanines (MPcs), metal nanoparticles (Au@Ag NPs), 2,2,6,6-tetramethyl(piperidin-1-yl)oxyl (TEMPO), maleimide and thymine for the sensing of target analytes such as ascorbic acid (AA), biothiols (cysteine, homocysteine and glutathione) and mercury ion (Hg²+). The design strategy and approach was based on the quenching of the fluorescence of the GQDs upon functionalization with the above-mentioned complexes, which could be restored in the presence of the target analytes (due to their specific interaction affinity with the complexes). For the detection of AA, GQDs were covalently and/or non-covalently conjugated to TEMPO-bearing complexes to form GQDs-4A-TEMPO and GQDs-TEMPO-MPc systems with nanomolar limits of detection. For the detection of biothiols, Au@Ag NPs and maleimide-bearing complexes (MPc), which have specific affinity to interact with biothiols, were deployed. Hg²+ detection involved the use of GQDs and/or MPcs with thiol and thymine groups, respectively. In addition, a smart sensing platform was designed for the dual detection of biothiols and Hg²+ using supramolecular hybrid of polyethyleneimine functionalized-GQDs and MPc-Au@Ag conjugate. The probe could detect, in a sequential manner, Hg²+ and biothiols with high sensitivity. Results obtained from the LODs of the probes showed that GQDs sensing performances could be enhanced in the presence of MPcs. The probes designed in this work were successfully deployed in the assays of the target analytes in real samples and the recoveries obtained confirmed the analytical applicability of the probes.

- Description: In the current age, companies are redesigning the way they perform daily operations based on the principles of the Fourth Industrial Revolution. Industry 4.0 will lead to the integration of the Internet of Things (IoT), cloud computing and mobilisation into the daily operations of companies across various industries which stay connected to guidance software by means of 3G or 4G SIM cards. This increasing demand for mobilisation and communication technologies has encouraged more interest from investors to invest in the Mobile Telecommunication Industry (MTI). The aforementioned leads to heightened competition among Mobile Telecommunication Service Providers (MTSP), already competing in a fiercely contested market. For service providers to guarantee success in such a highly competitive market, companies should endeavour to provide superior quality and customer-centric services to retain and attract customers. Service providers that provide their customers with quality experiences gain a competitive advantage over rival firms and enjoy increased financial returns. Thus, companies measure their service quality (SQ) continuously to understand what consumers need and want as well as to ascertain how customers perceive the quality of service provision of the organisation. Therefore, this research study introduces and discusses various SQ measurement instruments and dimensions that may be relevant for a MTSP to consider when measuring SQ. This study further provides a broad overview of the latest techniques and best practices that popular service providers have applied globally, to enhance their SQ measurement In order to facilitate the SQ measurement process, researchers have designed different instruments, tailored for measuring SQ in various particular industries, by identifying and incorporating relevant industry-specific SQ dimensions. This enables the measurement of the customer perceived performance of each individual dimension for a particular service provided in a specific industry. In order to initiate a SQ measurement project, companies employ a variety of techniques to collect data. In this research study, the SQ data collection technique and resultant data set of a South African Mobile Telecommunication Service Provider (SAMTSP) were analysed to evaluate present service quality processes and provide guidelines to a SAMTSP on improved processes to implement to determine its service quality levels. Eight independent variables were identified from the quantitative data in the service quality data set provided by a SAMTSP for the purposes of this study. The dependent variable was identified as Performance which served as the unit of measurement for the independent variables. The qualitative data analysis applied to the qualitative data in the provided data set, revealed three Attitudes (key patterns) namely Positive, Neutral and Negative. Moreover, 14 themes were extracted from these Attitudes and which provide deeper insight into customer sentiments with regards to the overall performance of a SAMTSP. The results indicated that the SAMTSP may not have targeted the necessary SQ dimensions. It was also found that the data collection technique employed by the SAMTSP to create the SQ data set had certain limitations that might have negatively impacted upon the relevance and quality of the SQ data collected. The findings further suggest that the MTSP could follow a better SQ measurement process.

- Description: Learners’ performance and the reasons for either achievement or failure in school has lo ng been a topic of debate. In early research on academic achievement, theorists, educators, biologists and psychologists traditionally focused on the learners from socially disadvantaged family backgrounds who underachieve. Much of the debate internationally centred on whether learner academic achievement / underachievement is a product of hereditary traits or the social context. In particular, arguments for and against whether the reasons for the achievement / underachievement of children from socially disadvantaged families are genetic or the social context in which they find themselves continue unabated. Such explanations do not provide insight into why it is that despite familial (genetic) and social circumstances (social disadvantage), some children succeed and/or are able to act outside expectations of failure. Little research has focused on those in the same or similar contexts who are achieving academic success despite their limiting circumstances and the reasons for their success. This study used a social realist lens to investigate the factors that shape the academic achievement of 12 learners in two rural senior secondary schools in Omusati region, Namibia. All 12 learners are from low socioeconomic family backgrounds. The data was collected through survey, interviews with learners, parents and teachers, field notes and document analysis. The main finding of the study show that contrary to research that portrayed learners’ achievement as determined either by heredity or social contexts, the 12 learners constantly used their agentic possibilities to navigate constraining structural and cultural conditions at regional, familial and school levels to achieve academic success. Their agency was shaped by the socioeconomic conditions in their lives, namely, socioeconomic deprivation; large extended families in rural households, lack of amenities and utilities in their families, participation in household chores, experience of family tragedies and of changes when they were young.

- Description: Orientation: Technology affects organisations both positively and negatively and in some instances technology factors can result in turnover intentions for certain employees of organisations. Research purpose: The main objective of the study was to investigate how technology-based job autonomy, technology-based job overload and technologybased job monitoring impact turnover intentions of employees. Motivation of the study: Exploring and understanding the relationship between technology factors and turnover intention amongst government employees to determine whether these factors affect government as much as they affect the private sector. Research design, approach and method: This research used a quantitative research approach. It drew a convenience sample of 182 employees (N= 182) from the South African Government. Main findings: The three main findings of the study were: Technology-based job autonomy was positively related to turnover intention. Technology-based job overload was found to be positively related to turnover intention. Finally, technology-based monitoring was found to be positively related to turnover intention. Practical/managerial implications: If organisations do not address the issue of monitoring and overload they are likely to experience many turnover intentions amongst the employees. Furthermore, the organisations with less autonomy are likely to lose their employees which means they will lose the resources that have been serving the organisation for a long time. This will also contribute to the organisation losing many funds as they would constantly have to train new employees. Contribution/value-add: The research adds value to the knowledge about the effects of technology factors on turnover intention by pointing out the reasons that lead to turnover intention.

- Description: Biofuel feedstock production can be a significant driver of landscape modification, ecosystem change and biodiversity loss. There is growing body of literature that shows how biofuel landscapes provide various ecosystem services (e.g., feedstock for fuel, carbon sequestration) and compromise other ecosystem services (e.g., food, freshwater services). These effects are context-specific and depend largely on prior land use conditions and feedstock production practices. Changes in the flow of ecosystem services due to the conversion of natural and agricultural areas can have ripple effects on human wellbeing. Despite some recent attempts to apply to biofuel settings concepts and methods rooted in the ecosystem services literature, this is the exception rather than the rule within both the biofuel and the ecosystem services research communities. This paper synthesizes the current knowledge about the impact of biofuels on ecosystem services. It focuses especially on the feedstock production phase and outlines the main mechanisms through which landscape conversion affects the provisions of ecosystem services. It proposes conceptually coherent indicators to reflect these mechanisms and offers a critical discussion of key issues at the interface of biofuels and ecosystem services.

- Description: In the tumultuous time we find ourselves, debates about pedagogy have taken centre stage once again. Concerns raised by the student protests of 2015 and 2016 have highlighted the urgent need to re-think traditional teaching, learning and assessment practices, as well as the development of decolonised and transformative curricula.Traditional notions of academic and professional development are now being tested and contested, insofar as they are able to respond to student challenges in appropriate, responsive, legitimate and relevant ways. As a professional organisation dedicated to supporting learning and teaching, the executive team of HELTASA responded to the challenge in this article by engaging with perspectives on the purpose, role and conceptualisation of academic development in the current decolonial moment in the South African Higher Education landscape. Critical processes that enable academics to engage, share thoughts and debate epistemological, pedagogical and methodological options to support students and academics are much needed. And the context and spirit in which these debates occur may be as important as the debates themselves.At its annual conference, the executive team facilitated a critical dialogue with conference delegates on the limitations and opportunities of AD in our current context. Given the diverse teaching and learning contexts and institutional differentiation in the sector, this article explores individual and collective theorised observations, reflections and experiences of the seven facilitators who led the CD. These reflections were analysed and discussed against the backdrop of AD as well as the affordances of CD as a participatory learning and engagement methodology. The findings showed that there is dire need to re-imagine, not only AD’s role but alternative forms of critical engagement in the sector.

Given the diverse teaching and learning contexts and institutional differentiation in the sector, this article explores individual and collective theorised observations, reflections and experiences of the seven facilitators who led the CD. These reflections were analysed and discussed against the backdrop of AD as well as the affordances of CD as a participatory learning and engagement methodology. The findings showed that there is dire need to re-imagine, not only AD’s role but alternative forms of critical engagement in the sector.

- Description: A series of structurally related BODIPY dyes were synthesised and characterised. Their photophysical properties were studied in order to determine whether they would be suitable candidates for use as photosensitisers in the photodynamic therapy (PDT) treatment of cancer. The synthesis of two highly fluorescent BODIPY cores was achieved via the acid-catalysed condensation of a pyrrole and a functionalised aldehyde. In order to promote intersystem crossing, and hence improve the singlet oxygen generation of these dyes, bromine atoms were added at the 2,6-positions of the BODIPY core. These dibrominated analogues showed good singlet oxygen quantum yields, and excellent photostability in ethanol. In order to red-shift the main spectral bands of the BODIPY dyes towards the therapeutic window, vinyl/ styryl groups were introduced at the 3-, 5-, and 7-positions via a modified Knoevengal condensation reaction. The addition of vinyl/ styryl groups to the BODIPY core caused an increase in fluorescence quantum yield as well as a decrease in singlet oxygen quantum yield with respect to the dibrominated analogues. However, two of the red-shifted BODIPY dyes still showed moderate singlet oxygen quantum yields. The use of BODIPY dyes in nonlinear optics (NLO) was explored. The nonlinear optical characterisations and optical limiting properties of a series of 3,5-dithienylenevinylene BODIPY dyes were studied, both in dimethylformamide (DMF) solution and when embedded in poly(bisphenol A carbonate) (PBC) as thin films. The 3,5-dithienylenevinylene BODIPY dyes showed typical nonlinear absorption behaviour, with reverse saturable absorption (RSA) profiles, indicating that they have potential as optical limiters. The second-order hyperpolarizability (Y), and third-order nonlinear susceptibility (/m[/(3)]) values are also reported for these dyes. The optical limiting values of one of the BODIPY dyes in solution, and two of the BODIPY-embedded PBC films, were below the maximum threshold of 0.95 J-cm-2. The effect of addition of substituents on the electronic structure of the BODIPY dyes was investigated using TD-DFT calculations. The calculated trends closely followed those determined experimentally.

- 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: There is growing recognition that the limited success in rural development policies in many developing countries, including South Africa, is mainly a result of the failure to conceptualize such interventions beyond agriculture and incorporate non-farm enterprises into the mix. Non-farm enterprises are increasingly viewed as having the potential to become one of the drivers of rural development. However, it is an area that remains poorly documented and dimly understood as it has received limited scholarly attention in recent years. The study was carried out in the rural areas of Port St John’s Local Municipality in the Eastern Cape Province of South Africa. The study was premised on the assumption that non-farm enterprises have the potential to become one of the drivers of rural development in terms of employment creation, income generation and diversification of the rural economy. The thesis demonstrates that the hope that non-farm enterprises can add value to the rural economy in terms of creating the much needed employment opportunities is still a goal to be realised. Nevertheless, the income generated by these enterprises is contributing immensely to household welfare, especially improving accessibility to food by poor households. The study recommends the implementation of tailor made capacity building and training programmes aimed at enhancing the skills of rural artisans. This is an area that requires state-mediated intervention to augment the rural economy in order to redress the uneven development of the past.
