    Sustainability of the KwaZulu-Natal creative sector: The KwaZulu-Natal Society of Arts as a case study
    (University of the Witwatersrand, Johannesburg, 2024) Shaw, Angela; Ntombela, Nontobeko
    This dissertation explores factors impacting sustainability in the KwaZulu-Natal (KZN) visual arts and crafts domain of the creative sector – and how these have played out in the case study, the KwaZulu- Natal Society of Arts (KZNSA), since its formation in 1905 and especially since 2000. The study asks how collaboration and refusal could contribute to the sustainability of the KZNSA. The theoretical framework of the study is grounded in sustainability theory and, using systems theory, explores modes of participation, whether collaboration or refusal and the resulting energy or inertia. It looks at how these could build on the latent talent and the tendency towards innovation found in KZN, and how they may contribute towards sustainability in the creative sector. The ecosystem of the case study, the KZNSA, contains the operating divisions of the organisation – the gallery, the shop and the café. Initiatives undertaken by these divisions such as forays into artist incubation projects, the Members’ Exhibition, education programming, gallery retail, online retail and art fairs are used to exemplify how collaboration and/or refusal impact the sustainability of the organisation. The operating divisions and their projects are themselves contained within a system of member-based governance with the KZNSA members, the Council and the Constitution as constituent elements in play. Broad themes describe the activities and context of the organisation – the environment, programming and commerce – and frame the interactions between entities in the KZNSA system. The focus of the study is to examine the dynamics between these entities, how they interact with each other and the resulting energy or inertia generated. This in turn provides clues to sustainable practice for the organisation that could be applied to the KZN creative sector.

    Adoption of digital dual supply networks by SMES in the Capricorn district of Limpopo Province in South Africa
    (University of the Witwatersrand, Johannesburg, 2022) Sefala, Maite
    This research investigates the adoption of digital tools, specifically Digital Dual-Supply Networks (DDSN), by Small and Medium Enterprises (SMEs) operating within the Capricorn District of the Limpopo Province in South Africa. As the digital landscape continues to evolve, SMEs face increasing pressure to integrate innovative technologies into their business operations. The study aims to understand the current state of digital tool adoption, the factors influencing adoption decisions, and the impact of DDSNs on the overall performance, sustainability, and growth of SMEs in the region. Thus, four parental concepts, namely, digital dual-supply network, sustainability, growth, and performance of the SMEs are investigated to establish an impact they could have on the SMEs in Limpopo province, South Africa. This study will follow a qualitative research design and data will be collected through interviews to gain comprehensive insights into the dynamics of digital tool adoption within the SME sector. The research will explore the challenges hindering adoption, identify successful cases, and analyse the strategic considerations that influence the decision-making process of SMEs when integrating DDSNs. Moreover, the study will also explore the context of the dual-channel digital supply chain network and its importance in the sustainability of the SMES as well as analysing the concepts of collaboration and digital transformation of Capricorn district SMEs within the ever-changing and market trends and demands. Digital Dual-Supply Networks (DDSNs) represent a paradigm shift in supply chain management, leveraging advanced digital technologies to create more agile and resilient networks. This research not only advances theoretical knowledge in the field but also offers practical implications for businesses contemplating or currently undergoing digital transformation through the adoption of DDSNs. The resulting framework aims to guide organizations in optimizing their supply chain processes, fostering innovation, and adapting to the dynamic landscape of the digital era. The findings of this research will contribute to the existing body of knowledge on technology adoption in SMEs, providing valuable insights for policymakers, business owners, and researchers interested in fostering digital transformation within the Capricorn District and similar regions. Ultimately, the study aims to offer practical recommendations to enhance the adoption of DDSNs among SMEs, promoting their sustainable growth and competitiveness in the ever-evolving digital business landscape. Keywords: SMEs; digitalization, collaboration, dual dual-channel digital supply chain network, sustainability, growth

    Would You Drink It? An Exploratory Study Gauging the Public’s Perceptions and Attitudes on the Use of Reclaimed Wastewater in South Africa
    (University of the Witwatersrand, Johannesburg, 2021) Prins, Franciscus X.; Thatcher, Andrew; Etale, Anita
    Increasing population figures globally, and in South Africa, and other factors, such as climate change could result in countries and regions suffering severe water scarcity. Alternative water sources, such as wastewater reclamation, are available which could bridge the supply and demand gap. Historically consumers have been against the use of water from water reclamation plants. This study aimed to determine consumers’ attitudes and key trade-offs toward alternative water sources, and to inform policy-and decision-makers for improved future public engagement. This could potentially improve the support for, and success, of future water reclamation plants. With the use of traditional surveys consumers’ willingness to consider alternative water sources are often determined after having assumed that they have existing knowledge of often complex topics. In this study, a decision pathway design allowed for information provision within an adaptive online survey with a set of linked questions. This encouraged the deliberate construction of opinions and views. In this way, respondents’ choices were more likely to be based on correct information before being asked to provide their opinions. By selecting one pathway information was revealed about respondents’ trade-offs and reasoning processes. Quantitative data were collected, and various demographical variables and responses were explored. Respondents’ most preferred water alternatives were provided at two points (at the start and at the end of the survey). The data revealed that there were changes between respondents most preferred alternative at the start and end of the survey. Furthermore, under situations of severe water scarcity most South African consumers would be in support of direct reclamation, however, respondents’ level of trust in the government, and the associated level of affect, could play a determining factor in the future successful implementation and operationalisation of water reclamation plants.

    Integrated electronic human resource management systems for front- line employees and mine safety performance
    (University of the Witwatersrand, Johannesburg, 2021) Nyelisani Clement , Mufamadi
    The South African mining industry heavily relies on manual labour, resulting insignificant risks to lives and production. Competency gaps, human behaviour, andviolations are major contributors to frequent accidents. Despite the implementation ofhuman resource management (HRM) systems, safety and productivity challengespersist, with base metals productivity declining annually by 0.3% from 2013 to 2017.Investing in competencies can enhance overall firm performance, as individualimprovements lead to better team and organizational performance.This study examined the impact of integrated electronic HRM (e-HRM) systems onsafety performance in mining. It explored the relationship between e-HRM practices,employee roles, and mine safety. The research utilized SPSS and PLS-SEM tools tovalidate and analyze data, testing eight hypotheses within a theoretical framework thatincluded performance management, HRM systems, and technological development.The findings showed that ability, opportunity, and motivation significantly and positivelyinfluence e-HRM practices, which in turn enhance employee roles, mine safetyperformance, and sustainable e-HRM systems.Sustainable e-HRM systems were identified as mediators that enhance e-HRMpractices and mine safety performance. However, the study could not substantiate theeffects of employee level, firm age, and industry experience on safety performance.Limitations included the cross-sectional study design and the omission of factors likeleadership and organizational culture. Despite these limitations, the study concludedthat sustainable e-HRM systems improve business success by integratingsustainability plans, ethical data management, and effective technology use, fosteringemployee autonomy and safety.The study suggests further longitudinal and qualitative research to evaluate the long-term sustainability of e-HRM improvements and their impact on safety performance.Comparative studies could also explore different system types and cultural variations,while investigating e-HRM's role in crisis management to reveal strategies fororganizational resilience

    When Less Is More – Tiny Housing As “Adequate” Housing
    (University of the Witwatersrand, Johannesburg, 2023) Kruger, Petronell; Pieterse, Marius
    The modern housing landscape is in flux with three key phenomena impacting the “adequacy”– the legal standard by which housing provision is measured – of housing policy, in South Africa, and worldwide. First, the “classic” housing crisis persists: high levels of homelessness, housing backlogs, and challenges related to government housing subsidies and service delivery continue. Second, there is international recognition of the impact of climate change on housing, the consequent need for climate-resilient housing, and reduced climate footprints of housing construction, maintenance and ownership. Third, physical housing size is increasing, despite the number of household members and available space for housing decreasing. This thesis considers these phenomena and contemplates the role of housing size within the evolving legal standard of “adequacy”, especially where size was often linked to the promotion of the right to health in light of communicable disease outbreaks. The thesis explores how tiny housing movements and different global norms on housing size can challenge conventional standards of housing adequacy. It considers that smaller dwellings are more affordable, less resource-intensive and, within the correct policy context, can lead to easier access to housing. The study lens of tiny housing is chosen due to its popularity throughout different income groups, based on growing concerns about consumerism, sustainability and communitarianism (albeit through a westernised lens). Accordingly, it allows for a discussion on the role of housing down-sizing without necessarily invoking a sense of “racing to the bottom”. To achieve the research aim, the following research questions are posed and answered in turn: What is “adequate” as a standard to measure housing? Does size matter for the standard of adequacy, and if so, how? Can tiny houses, as a representation of very small housing types, be deemed adequate? If tiny housing can meet the adequacy standard, how should the law facilitate the self-realisation of tiny housing, or, alternatively, as a viable form of public housing? The thesis comprises six chapters. The first chapter introduces the above-mentioned phenomena and study lens. The second chapter examines the legal and social barriers and facilitators for tiny housing in both private and public contexts through a comparative study of selected jurisdictions, chosen to represent different social, cultural and geographic contexts in which housing size requirements developed. The jurisdictions were also selected based on data accessibility and availability. The third chapter is a content analysis of theoretical aspects of adequacy in international and South African housing and human rights law. The fourth chapter is a critical analysis of building regulations and planning laws in South Africa, tracing their history and assessing their current form, with a focus on how they structure the self-realisation of access to tiny housing as adequate housing. The fifth chapter considers government public housing programs, policy approaches to housing size and its trade-offs with other adequacy factors in enabling access to tiny housing for people without the means to self-realise the right to adequate housing. Chapter six presents the answers to the research questions as explored through the various chapters and presents the overall findings of the study

    Good corporate governance in state-owned entities: challenges and compliance
    (University of the Witwatersrand, Johannesburg, 2024) Mokuena, Medi Moira; Kawadza, Herbet
    This research explores the state of good corporate governance in state-owned entities. It does so by locating good corporate governance in the state-owned entities’ operating environment. This research raises the failure of the executive managers, the non-executive directors, and the executive authorities to appreciate this powerful tool as a key to the success of the state-owned entities. The state-owned entities are significant participants in South Africa's economy. The number of state-owned entities, the size of some, and their role in the country's economy make good corporate governance imperative. The nonchalant approach of the state-owned entities management to this phenomenon is concerning because its effect on the economy and the delivery of services to the people has far-reaching negative consequences. In most instances, unethical executive managers and non-executive directors consider it inconvenient and a nuisance. The competitiveness of the economy, success and sustainability of the state-owned entities is unachievable without good corporate governance. The accounting authorities must know and understand the purpose of state-owned entities and the relevance of good corporate governance. They must own it, embrace it and oversee its effectuation throughout the organisation without fail. Once adopted, good corporate governance binds the accounting authorities, the executive managers, and all the employees in the state-owned entities, including the executive officers. There are laws and other guidelines in place to modulate good corporate governance. The overarching law is the Constitution of the Republic of South Africa, 1996. These could be better. However, if properly implemented and not manipulated for nefarious reasons to the detriment of the state-owned entities, the government will realise its goals, and the public will benefit. Bad corporate governance opens the door for corruption, bribery, fraud, financial mismanagement, and money laundering. This problem is common in Southern Africa. For instance, Botswana and Namibia also have good corporate governance challenges in their state-owned entities. Their good corporate governance is premised on the King Codes and international instruments. Hence, good corporate governance must be applied in the management of state-owned entities. The quality of management and execution in state-owned entities determine their failure or success. With the help of the private sector enablers, theirprospect of success is limited

    The effects of coronavirus on SMEs business performance, technology adaptation, financial innovation, and sustainability
    (University of the Witwatersrand, Johannesburg, 2024) Kolobe, Benjamin; Maisela, Sikhumbuzo
    Businesses have been severely impacted by the COVID-19 pandemic, which has resulted in significant economic hardship. An analysis of COVID-19's impact on Small Medium Sized enterprises (SMEs) shows that these businesses' and their employees' financial outcomes are probably going to get worse before getting better. The main issue is that small and medium-sized business owners have restricted access to capital and innovative strategies, which has made it challenging for them to deal with the tight constraints. As a result, many SMEs have had to adopt innovative financial and technological strategies to promote sustainability and prevent closure (Puddister & Small, 2020). This study examines the impact on business performance, technology adaptation, financial innovation, sustainability, and lockdown restrictions of SMEs during the pandemic. An online questionnaire with 30 closed-ended questions was administered to entrepreneurs in the retail sector across Gauteng. The following inquiries are addressed in the study: What impact has the coronavirus had on SMEs' ability to do business? How has technology adoption improved small and medium- sized enterprises' performance during the coronavirus lockdowns? Is there a chance that financial innovation may sustain SMEs throughout the pandemic? Has the coronavirus epidemic affected SMEs' ability to survive? Using non-parametric tests, the researcher examined the correlations between the independent and dependent variables for each of the four hypotheses using IBM SPSS. The associations between the variables were examined using inferential statistics such as Spearman's rho correlation function, multinominal logistic regression, generalized linear model, and ordinal linear regression. All four of the hypothesis' correlations were determined to be significant. This study suggests that fostering financial inclusion, promoting technology adoption through training and grants, and encouraging innovative financial approaches can empower SMEs to navigate pandemic challenges and build resilience. Proactive policy interventions and support systems tailored to SMEs are crucial to mitigating the pandemic's economic consequences and promoting long-term sustainability

    From Coal to Renewable Energy: Perspectives on South Africa's Energy Transition for a Sustainable Future.
    (University of the Witwatersrand, Johannesburg, 2024) Sebele, Temperance; Simatele, Mulala Danny
    South Africa has been experiencing an unstable electricity supply for years, leading to periods of load shedding from 2007 up to the present date. The electricity shortages have been attributed to distinct reasons, ranging from inefficient coal supply, skills shortages, sabotage by employees and lack of maintenance for nearly sixteen years. In addition to the electricity supply shortages, coal-fired electricity generation is responsible for roughly 80 per cent of South Africa’s total greenhouse gas emissions due to fossil fuel dependence, leading to many health, climate, and environmental challenges. To address the challenges related to fossil fuel dependency, moving to Renewable Energy sources that are climate and environmentally friendly is a necessity. The aim of this study was to investigate the optimal approaches that South Africa can embark on for a successful transition from coal to renewables. The institutional, policy, and strategic frameworks that exist within which South Africa can embark on for a successful transition were explored. Furthermore, the study sought to identify the challenges, and opportunities that exist or hinder the transition in South Africa. Lastly, the study explored how developments in the international policy frameworks influence South Africa’s ambitions to transition to renewables. The study is best suited to the pragmatism approach, and data were collected through the reviewing of literature, key-informant interviews, and questionnaires. A mixed-methods strategy that involved gathering both qualitative and quantitative data was employed and primary and secondary sources of data were used. The primary data sources used included key informants from various private and public institutions with an interest in South Africa’s energy matters such as ESKOM, SANEDI, SANEA, SAREC, SAPVIA, SAWEA, SAIPPA and NECSA. The non-probability sampling method was used in the participants’ selection from the sampled study institutions, with a combination of judgmental, snowballing and convenience sampling procedures employed at distinct phases of the research. Data collected was analysed both quantitatively and qualitatively, with interviews text data transcribed and analysed through manual tabulation and thematic analysis, and presented in graphs generated from Microsoft Excel, and the data from questionnaires analysed through the IBM Statistical Package for the Social Sciences (SPSS) software. The study revealed that the government played mainly four leading roles in the energy transition, which were providing financial support, legislative direction, institutional direction, and project oversight. Financial support is provided through financing projects and setting up financing policies that promote renewable energy investment, and legislative direction is provided through policy development and ensuring efficient implementation. Providing institutional direction is ensured through ensuring coordination across all spheres of government and capacitating institutions involved in the transition, and project oversight is provided through setting out renewable energy capacity determinations. The study further identified key energy transition elements, namely infrastructure, governance, legislation, stakeholders’ perceptions, and skills and strategies for a successful transition, which included channelling adequate financial resources to the renewable energy sector, privatisation of the electricity utility, diversification, rolling out bid windows, improving the legislative framework, improving grid access and integration, skills development, localisation of RE components manufacturing, providing incentives, and increasing consumer awareness about renewables. Several barriers to the transition were also identified, which included political interference and corruption, lack of financial investment, policies/legislation inadequacy, inconsistency in rolling out bidding windows, ESKOM’s monopoly, high cost of renewables, deficiency of incentives, skills and technology, labour unions, and deficiency of awareness on alternatives. The study recommends multisector reskilling of employees, since not all employees in the coal value chain may be interested in or able to be absorbed in the Renewable Energy sector. Furthermore, the government should fund and support progressive technologies and business models, improve the quality of institutions through merit-based appointments and uprooting corruption, privatisation of ESKOM to create opportunities for new entrants in the electricity market and improve stakeholder engagement and community support programmes. The UNFCCC must develop and ensure the implementation of enforcement strategies for holding countries accountable for their climate commitments for the transition to be realised

    Perspectives on the role of stakeholder engagement and participation in river basin management in South Africa: a study of the hennops river
    (University of the Witwatersrand, Johannesburg, 2024) James, Lucien; Simatele, Mulala Danny
    As a country that already faces hydrological and climatological challenges, South Africa’s socio-economic situation further complicates River Basin Management. This is observable through the state of rivers in the Gauteng Province such as the Hennops River. Like other rivers across the country, the state of the Hennops River is alarming, being affected by multiple sources of pollution. The state of the Hennops River Basin is observably affected by Tembisa, a poor former township area that has contributed to the pollution of the upstream Kaalspruit tributary. While the community of Tembisa contributes to the Hennops’ degradation, the potential of stakeholder engagement and community participation in Integrated River Basin Management is yet to be harnessed. The aim of this study was to investigate in what ways stakeholder and community engagement, mobilisation, as well as participation can be harnessed to promote sustainable River Basin Management considering the Hennops River Basin as a case study. The objectives of this study were to (1) analyse existing policies and frameworks which promote stakeholder engagement and community participation in River Basin Management in South Africa, (2) identify challenges and opportunities that hamper and facilitate sustainable River Basin Management through stakeholder engagement and community participation in South Africa, taking the Hennops River Basin as a case study, (3) create a sustainable model through which stakeholder engagement and community participation can be harnessed towards effective River Basin Management, and (4) Contribute to the body of knowledge on the role of stakeholder engagement and community participation in River Basin Management. Through a research design involving key stakeholders and the community, new insight was gathered about their potential through engagement and participation. Data were gathered from Key Informants, interviews, focus group discussions, as well as clean-up campaigns, which included a campaign hosted by the researcher. Findings of this study suggest that although policy supports the engagement, participation, as well as the mobilisation of stakeholders and the community, implementation thereof has been challenged. At community level, implementation is further challenged through community disinterest, a lack of support or funding for disparate initiatives, and lack of political will to address community issues. Key stakeholders, namely NGOs have taken it upon themselves to address River Basin Management. However, their initiatives are self-reliant and therefore unsustainable. Several conceptual models to address River Basin Management in South Africa are proposed. These models address (1) the implementation of policy through the establishment of effective institutions, (2) the role of the NGO in River Basin Management, (3) the funding of small projects or initiatives, (4) an approach to wicked problems in the community, and (5) the relationship between government, stakeholders, and the community. Together, these models are argued as some of the ways the potential role of stakeholder engagement and community participation can be harnessed as part of a framework for sustainable River Basin Management in South Africa. Opportunities exist to better understand stakeholder engagement and community participation, particularly in the context of leadership and agency. The framework presented as the result of this study opens the doorway to new possibilities for the implementation of policy and new approaches to water governance

    Compost-assisted phytoremediation of mine tailings and footprint areas using chrysopogon zizanioides (l) roberty enhanced with moringa leaf extract biostimulant in the Witwatersrand goldfields of South Africa: a sustainability initiative
    (University of the Witwatersrand, Johannesburg, 2024) Mlalazi, Nkanyiso; Chimuka, Luke; Simatele, Mulala Danny
    In the Witwatersrand goldfields of South Africa, mine tailings and footprint areas are significant environmental problems because they are major sources of toxic metals. These metals can leach into soils, and both surface and ground water, causing serious risks to human, animal, and plant life. In this study, the compost-assisted phytoremediation of tailing storage facilities (TSFs) and footprint soil using Chrysopogon zizanioides (vetiver grass) enhanced with moringa leaf extract (MLE) was investigated. A greenhouse experiment was conducted to identify the most favorable parameters, and was followed by a field study to test the optimized parameters under real-environment settings. For the greenhouse experiment, a 3×2×2 fully crossed factorial design was used to determine the optimum variables. Vetiver growth was assessed under three compost concentrations (0%, 30% and 60%), two types of MLE (laboratory extracted MLE and commercial MLE) and two application regimens (once a week and twice a week) were used. The biomass and metal concentrations in the vetiver grass roots and leaves were measured after sixteen weeks followed by a two-way ANOVA analysis and the post-hoc tests. All the vetiver that was planted in 0% compost died within four weeks regardless of the MLE treatment. Vetiver grass planted on the 60% compost amendments and sprayed with laboratory extracted MLE had the highest biomass production, followed by plants grown in 30% compost amendments and sprayed with commercial biostimulant. However, the heavy metal removal or uptake data by the plant was inconclusive, as most of the toxic metals were not removed by vetiver grass which was attributed to the effect of compost. Based on biomass data, the 30% compost amendment and commercial bio-stimulant was the ideal treatments for the phytoremediation of gold mine tailings using vetiver grass. Although metal accumulation by plants is one of the attributes considered in phytoremediation, it is not the most significant factor in the phytostabilisation process. Plant growth and biomass production are the most significant, therefore it is concluded that vetiver, MLE and compost can be used in the phytostabilisation of gold mine tailings, however reduction in compost may be considered in future to improve the accumulation of metals in the roots for improved results. Following the conclusion of the greenhouse study, a field study was conducted during the rainy season of 2021. Two field experiments were carried out concurrently at two sites: the footprint area (that was used as a rock dump) and the tailings storage facility (TSF 4). A split-plot design was used in this study. The experiment at each site assumed a 3×1×2 factorial design, with three levels of compost treatment (0%, 15% and 30%), 1 level of vetiver cultivar (Chrysopogon zizanioides), and 2 levels of MLE treatment (commercial MLE and tap water, both sprayed once a week). Three blocks measuring 1 m × 2 m, each with 20 holes filled with equal amounts of soil amended with the different compost levels were prepared in triplicates. A single vetiver grass slip was planted in each hole. The blocks were then divided into 2 sections, each with 10 holes, and commercial MLE was sprayed on one section, while only water was sprayed on the other section once a week. After sixteen weeks, three plants were harvested from each section and the number of leaves, leaf length, number of tillers, biomass for roots and leaves and element concentrations were measured. Data analysis was done using two-way ANOVA
