- Description: ‘Our Ocean Is Sacred, You Can’t Mine Heaven’ was a ground-breaking South African public storytelling initiative that not only emphasised the intrinsic and cultural value of the ocean but also served as a living-customary lore/law classroom. This exhibition challenged conventional archiving, promoting diversity, sovereignty and evolving ‘meaning-making,’ fostering inclusivity and justice-oriented documentation in ocean knowledge. The authors worked alongside Indigenous coastal communities and Small-Scale Fishers (SSF), who were aligned with movements defending the ocean against unchecked Blue Economy expansion in South Africa. The chapter delves into how artist-led practices, strategically embedded with legal research, played a pivotal role in a recent court ruling favouring Indigenous and SSF applicants. This victory renewed attention on ocean heritages in legal processes, highlighting the potential for expanding evidence ‘an-archives.’ The collaboration with coastal communities and SSF against unbridled ocean development used art to secure a court win, reshaping South African law and challenging norms in ocean development. This chapter explores art’s role in legal innovation, contributing to the ongoing struggle for justice and the decolonisation of blue economy narratives and processes in South Africa.

- Description: Conventional definitions of development can be linked to socio-economic and cultural impositions of the Global North on developing societies. These development frameworks were inherited from the colonial system, which devalued local ways of knowing, being, and developing and continues to do so. Through a transdisciplinary or Boundary Crossing environmental case study that interrogates the use of heritage skills and knowledge for nature-based solutions relating to coastal shore regeneration, this chapter reflects on experiences of knowledge co-creation in the rural Eastern Cape Province setting of South Africa. Through the lens of African Musical Arts, which includes song and dance, storytelling, heritage skills, soundscapes, and more, this research seeks to shift the project perceptions of the scientists, engaged scholars, pracademics, practitioners and community researchers involved, from simple to multi-dimensional viewpoints. Using Traditional Cultural Expressions (TCEs) as catalysts, our goal is to emancipate transmission of knowledge from a developmental to an empowerment framework. Using the diverse disciplinary backgrounds of the authors, this chapter allows for a holistic examination of the development of an Audio Postcards exhibition, while interrogating the project centred on African theories, ecologies, and knowledge development.

- Description: Taxonomic identification of arbuscular mycorrhizal (AM) fungal spores extracted directly from the field is sometimes difficult because spores are often degraded or parasitized by other organisms. Single-spore inoculation of a suitable host plant allows for establishing monosporic cultures of AM fungi. This study aimed to propagate AM fungal spores isolated from maize soil using single spores for morphological characterization. First, trap cultures were established to trigger the sporulation of AM fungal species. Second, trap cultures were established with individual morphotypes by picking up only one spore under a dissecting microscope and transferring it to a small triangle of sterilized filter paper, which was then carefully inoculated below a root from germinated sorghum seeds in each pot and covered with a sterile substrate. All pots were placed in sunbags and maintained in a plant growth room for 120 days.

- Description: The need for more attention to the social and human dimensions in global change sciences and natural resources management requires in-depth understandings of transformative approaches and processes. More inclusive and systemic approaches are needed that embrace complexity and support transformative learning, shifts in power relations, collective and relational agency and structural transformations for adaptive and innovative governance. Scientific understanding of how such change can be brought about is still limited. In this paper, which sets the scene for this Special Issue, we develop a conceptual framework for analyzing transformative processes across a range of diverse cases. Aspects of the conceptual framework are applied, tested and elaborated in three following papers in the Special Issue, deepening understanding of how transformative change in complex social-ecological systems may originate at nexus boundary zones such as that portrayed by the water-food-energy nexus. Specifically, the paper conceptually elaborates four iteratively related dynamics of transformative learning, transforming power relations, transformative agency and transforming structures which intersect in transformation processes. The perspectives offer tools for cross case analysis in the longer term, but also tools for supporting co-engaged, generative research processes.

- Description: The South African pharmaceutical sector is Africa's largest and most advanced but heavily depends on imported products and active pharmaceutical ingredients to meet its demands. The status quo is due to low intra-industry trade, which is necessary to induce innovation and technological progress essential for accelerating local production, export growth and reducing dependence on imports. AIM: The primary objective of this article was to examine intra-industry trade in South Africa's pharmaceutical sector and subsequently, total factor productivity (TFP) as a key driver of intra-industry trade. Intra-industry trade was measured using data obtained from the United Nations Conference on Trade and Development databases, while the TFP was measured using data from the South African Reserve Bank (SARB) covering 2001-2021.

- Description: The notion of ‘sexual justice’ has gained traction in academic and policy arenas in recent years. This paper presents a scoping literature review of the regimes of truth, following Foucault, of ‘sexual justice’ appearing in the scientific literature from 2012 to 2022. Thirty-eight papers were coded using (1) content analysis of the studies’ central problematics, the programmes referred to, and institutional location(s); and (2) thematic analysis of how the notion was deployed. Central problematics centred on (1) critiques of, or alternatives to, dominant approaches to sexual and reproductive health; and (2) highlighting injustices. As such, ‘sexual justice’ is fighting for legitimacy in the truth stakes. There is a distinct paucity of papers tackling the translation of ‘sexual justice’ into practice. South Africa dominates as the site in which papers on ‘sexual justice’ have been produced, but there is a lack of South-South collaboration. Two themes were apparent around which conceptions of sexual justice cohere. Firstly, sexual justice is seen as a vital, yet politically ambivalent goal, with neoliberal co-optation of progressive rights agendas being warned against. Secondly, sexual justice is viewed as a means, in which sexual justice is described as having potential to repair established frameworks’ shortcomings and oppressive legacies.

- Description: A key responsibility of academic scholarship is to further develop the field under investigation and to critically evaluate how it is responding to challenges from both inside and outside of the field of enquiry. This article offers an overview of whether the scholarship published in geography education (GE) from the perspective of the Commission for Geography Education (CGE) Springer book series is sufficiently engaging with contemporary global challenges and education discourses. Guided by the 2022 IGU-CGE Rennes Conference’s three axes: curriculum renewal, pedagogy and teacher training, the article discusses the findings of a meta-analysis of the six books published in the CGE Springer series in the past five years (2017 to 2021).The thematic analysis shows that GE is engaging with global realities of environment and sustainability, climate change, globalisation and the importance of powerful knowledge for understanding and engaging with complex, often controversial issues. But there are also gaps and absences in terms of who is producing knowledge and from where knowledge is being generated. We contend that the book series is well placed to support the community in addressing global concerns and the related transformative pedagogies needed to enact them. However, we also suggest that the publications at this point in time have yet to fully grasp the specifics needed for the challenges that lie ahead. Some preliminary considerations for advancing the field through future publications are offered. These may be useful to GE researchers and scholars in different regions of the world.

- Description: Human capital (HC) has increasingly been identified as a driver of economic development, with the potential to reduce income inequality, which, in South Africa, originates in the labour market. HC is, however, a complex concept to measure. This study uses Fields’ regression-based decomposition method to analyse the relationships between income inequality and HC in South Africa. The Fields method allows for the analysis of the impact of several factors contributing to HC on the distribution of a measure of income. Data from the National Income Dynamics Study (NIDS) wave 1 (2008) and 5 (2017) are used. The findings suggest that increasing educational attainment, through improved school quality for all, would likely play a key role in reducing income inequality in South Africa. Furthermore, the large role of education attainment in explaining household income inequality supports the use of education attainment as a proxy for HC in South Africa.

- Description: Agricultural waste is enriched with a variety of environmentally friendly materials that can potentially boost economic growth, reduce the spread of contagious diseases, and serve as a carbon-free renewable energy bioresource. Biopolymers produced from agricultural waste have a range of applications in medicine, agriculture, pharmaceutics, and industrial factories. The chemical extraction of biopolymers from biomass requires a series of alternating alkali, acid, and alkali treatments at controlled temperatures. Chemical extraction of plant-based biopolymers requires elevated temperatures (70–100°C), while for animal and sea organism-based biopolymers, moderate temperatures of 25–60°C are used. The obtained biopolymers are functionalized into various materials for application in a wide range of industries. The reported functional materials are loaded with inorganic nanomaterials, plant extracts, and organic compounds, which resulted in a synergistic effect and enhanced activity of the materials. Several researchers have synthesized biopolymers with synthetic polymers to improve their bioavailability, tensile strength, shelf life, and UV adsorption. This review article reports the extraction techniques of biopolymers from agricultural waste and their application in wound healing, water treatment, food storage, passive cooling, and cosmetics. The dearth of scientific articles on the applications of biopolymers generated from agricultural waste produced from food crops grown in Africa is a motivation for the present compilation.

- Description: Moore’s Law is usually interpreted as a prediction of how many transistors you can buy for the same money at some future date. It can also be interpreted as how long you need to wait until a given number of transistors falls below a target price. An example of this reverse-application of Moore’s Law is transitions such as the emergence of microprocessors competitive with traditional larger-scale computers and the emergence of smartphones. Since the late 1990s, it has become increasingly common for growth in transistors to equate to more CPUs (cores) per die. Recent designs have over 50 billion transistors and far more potential parallelism than can be supported by memory. I argue the case for a rebalancing of design goals with a much larger, faster on-chip memory and a CPU that is designed around this memory system. The proposal: a Cray-class vector CPU on a die with 1 Gibyte of static RAM, or Crayon (for Cray on a chip). The kind of organization classically used by Cray vector supercomputers is feasible to achieve on a single chip. I argue that a design like this can use the available memory bandwidth, as opposed to over-CPU designs with a large number of cores and GPU threads that are memory limited and propose how such a design could be used.

- Description: Environmental filtering (EF), the abiotic exclusion of species, can have first order, direct effects with cascading consequences for population dynamics, especially at range edges where abiotic conditions are suboptimal. Abiotic stress gradients associated with EF may also drive indirect second order effects, including exacerbating the effects of competitors, disease, and parasites on marginal populations because of suboptimal physiological performance. We predicted a cascade of first and second order EF-associated effects on marginal populations of the invasive mussel Mytilus galloprovincialis, plus a third order effect of EF of increased epibiont load due to second order shell degradation by endoliths. Mussel populations on rocky shores were surveyed across 850 km of the south–southeast coast of South Africa, from the species' warm-edge range limit to sites in the centre of their distribution, to quantify second order (endolithic shell degradation) and third order (number of barnacle epibionts) EF-associated effects as a function of along-shore distance from the range edge. Inshore temperature data were interpolated from the literature.

- Description: For many Zimbabweans, Morgan Richard Tsvangirai (1952–2018) became the face of courage and hope during his political career. Tsvangirai was subjected to and witnessed political violence, physical abuse, brutality, emotional humiliation, unlawful detentions, and persecution. He challenged the ruling party in Zimbabwe, and his leadership gave many people hope for the future. In the context of living in a colonial era, poverty, and having to endure the brutality of the Mugabe era, he lived a meaningful life that saw him becoming a Prime Minister of Zimbabwe (2009–2013). This single-case study explores and describes Tsvangirai’s life and interprets it in terms of Frankl’s existential theory. More specifically, Tsvangirai’s life is interpreted from the perspective of Frankl’s three triads, the fundamental, meaning, and tragic triads, as well as the noetic dimension. Tsvangirai was selected through purposive sampling based on his important role in Zimbabwean politics. The primary source of data was biographical and autobiographical publications. The findings indicate that Tsvangirai shifted emphasis within the meaning triad in living a meaningful life and that he was able to use the human capacity of self-distancing/detachment and self-transcendence to find meaning in his life. This chapter sheds light on how individuals make sense of their circumstances and search for meaning and purpose in adverse conditions. It also contributes towards the development of psychobiographical research among non-WEIRD samples.

- Description: Significance Statement In the last decades, many coastal areas have observed dramatic changes in marine ecosystems, due to anthropogenic and environmental alterations. The general absence of long-term data sets in the marine environment and, more specifically, on benthic and demersal communities represents a severe issue for management and conservation. We propose to incorporate the small-scale fishers’ knowledge and science for better policy recommendations, both in terms of fisheries optimization and resource conservation. Based on two different cases of study with diverse ecosystems, we explore the combination of quantitative and qualitative tools, and participative techniques used to incorporate fishers’ local ecological knowledge. The results highlight fishers’ capacity to identify coastal and marine landscapes resources and changes, reinforcing and complementing the scientific assessment.

- Description: This chapter assesses the use of Information and Telecommunication Technologies (ICTs) for social and community learning to achieve sustainable development in rural communities in Africa. It focuses on new and emerging trends in the cooperation between the African Union and European Union (AU–EU) and links two thematic areas; namely green transitions and digital transformations. The chapter highlights low-cost and effective digital learning solutions. It is based on a literature review and cases that provide insight into potential AU–EU cooperation and the “leave no one behind” agenda. The chapter argues that in addition to digital technology transfer, innovation and investments are needed in building a learning-centred support for green transitioning and digital cooperation. Hence, we focus on transformative learning opportunities and informal Education for Sustainable Development (ESD). In response to ICTs becoming a catalyst for such a transformation, we seek insights into how constructive AU–EU cooperation and co-learning can pave ways for societal transformations, particularly in rural communities.

- Description: In this article we argue for the need to take the moral voices of children and youth seriously particularly in times of the Anthropocene. Drawing on theories in ethics by John Wall, moral development according to Mark B. Tappan, and education in line with the works by Vygotsky, we construct a conceptual framework where the notions ‘narrative,’ ‘moral authorship’ and ‘free will’ can open new creative understandings of human ethical competence; a competence based in a relational, contextual and societal-cultural understanding of human existence. The use of our framework is illustrated in interpretations of empirical research with children demonstrating concerns of theirs in relation to climate change. The article concludes with reflections on the kind of education that can be inspired by this framework and the taking of children’s voices seriously, as well as pointing to challenges also to the grown-up world.

- Description: This paper seeks to identify the differentiated impacts of the crisis on specific groups of informal workers. The analysis draws on official nationally representative labour force surveys collected quarterly by South Africa's national statistical agency (Statistics South Africa). Based on an analysis of six quarters of labour market data (with the first quarter of 2020 as the 'pre-COVID' baseline), the paper aims to identify the labour market impacts of the first three waves of the pandemic and of one of the world's strictest 'lockdowns' (as it was described at the time-in April 2020). In investigating the contours of the pandemic's impact on the South African informal economy, the paper focuses, in particular, on the different impacts by gender, sector, and status in employment. The findings show that both relative and absolute job losses have been greater in the informal economy, while the rate and level of recovery have been greater for formal employment. Further, the data suggest uneven impacts within the informal economy with women informal workers, those working in the informal sector and those in retail and community and social services being particularly hard hit. The pandemic period has thus widened pre-existing inequalities and fault lines. In policy terms, this suggests that the informal economy should be a priority in economic recovery efforts but also that support requires differentiated approaches and a range of measures

- Description: Globally, nations depend on small businesses as engines for economic growth. Small to Medium Tourism Enterprises (SMTEs), as part of the small business sector, are increasingly becoming important in terms of job creation, wealth creation and driving economic growth in smaller rural geographic areas. Utilising a mixed research approach, the paper identifies characteristics of SMTEs in Matatiele and Cedarville with the intention of identifying specific ways in which they can be supported to attain their real potential in enabling economic development in rural environment. Purposive sampling method was used to select respondents and self-administered questionnaires utilised to gather relevant data from managers/owners. The results indicate that the rural tourism is dominated by female-owned enterprises primarily offering accommodation services. Most of the enterprises have been in operation for a period of more than five years which points to potential growth as they are able to survive. The results further show that the businesses that participated in the survey intent employing more full-time employees. Furthermore, the results underscore that there is lack of local government support to promote entrepreneurship in the SMTEs sector particularly those that are located in the rural environment. The findings elucidate the ability of SMTEs to greatly reduce the high unemployment in rural economies if appropriate systems are put in place to support these enterprises. These findings have implications for the national, provincial and local government spheres in South Africa in their quest to create job opportunities in rural areas through entrepreneurship and SMTEs in order to provide impetus to the Eastern Cape Province and South African Economy.

- Description: Futures analysis methods can help people to think constructively and systematically about the future and advance our understanding of change and uncertainty in complex social-ecological systems (SES). This is important because there is not one single predictable future but multiple ones, depending on the complex, unpredictable interplays and interactions of actors, institutions, ecological processes and other elements of the system and its dynamics. Actively developing ideas, images and/or stories about different futures can enable us to make different choices and take different actions in the present in relation to, for example, risk mitigation, adaptation, resource allocation and strategy development, which can help build more sustainable and just futures.

- Description: Computational thinking (CT) is gaining recognition as an important skill for learners in both Computer Science (CS) and several other disciplines, including mathematics. In addition, researchers have shown that there is a direct correlation between poor mathematical skills and the high attrition rate of CS undergraduates. This research investigates the use of nine core CT skills in the South African Grades 10–12 Mathematics curriculum by mapping these skills to the objectives given in each of the topics in the curriculum. The artefact developed shows that all the identified CT skills are used in the curriculum. With the use of this mapping, future research on interventions to develop these skills through mathematics at secondary school, should produce school leavers with better mathematical and problem solving abilities, which in turn, might contribute to better success rates in CS university courses.

- Description: Malaria elimination can benefit from time and cost-efficient approaches for antimalarials such as drug repurposing. In this work, 796 DrugBank compounds were screened against 36 Plasmodium falciparum targets using QuickVina-W. Hits were selected after rescoring using GRaph Interaction Matching (GRIM) and ligand efficiency metrics: surface efficiency index (SEI), binding efficiency index (BEI) and lipophilic efficiency (LipE). They were further evaluated in Molecular dynamics (MD). Twenty-five protein–ligand complexes were finally retained from the 28,656 (36×796) dockings.
