In South African higher education institutions, the student protests of 2015-2016 called for the decolonisation of higher education spaces and equal access to these spaces. We collected data from students and lecturers over the period of one year in order to better understand the reactions of students and lecturers and the effects the protests had on their experiences. Perspectives of affective theory, decolonisation and social justice were used. It was discovered that the protests had a great affective impact on participants. Strong emotions and beliefs affected the relationships between students and lecturers and African centrality was suggested as a framework for curriculum change. Some settler perspectives emerged and polarisation was evident. It is our hope that lecturers could use this research to assist them in decolonising their spaces of teaching and learning.

Background: Cyclopia is endemic to regions of the Cape Floristic Region across the Eastern and Western Cape provinces of South Africa and is commonly known as honeybush. Honeybush has historically been used as an herbal tea, and has proven medicinal properties. Honeybush biomass and extracts are used in the functional foods and cosmetics sectors, both locally and overseas. The growing demand for honeybush calls for increased agricultural production and a shift away from the predominantly wild harvested supply.Objectives: The current study aimed to address the lack of baseline knowledge on honeybush phenology and its associated arthropod community to advance sustainable production of commercially valued plants in the genus.Method: The study was conducted on wild and cultivated Cyclopia species (Cyclopia maculata and Cyclopia genistoides) at respective sites in the Overberg region. Sampling took place from April 2014 to April 2015 using qualitative methods for recording seasonal honeybush phenology and suction sampling for aboveground arthropods. Focal insect taxa (Coleoptera, Hemiptera, Thysanoptera, Lepidoptera and Hymenoptera) were sorted and identified to family level and classified into functional feeding guilds.Results: Qualitative phenology observations of wild C. maculata and cultivated C. genistoides indicated a high level of congruency in seasonality of phenophase stages. Associated arthropod assemblages contained a diversity of families per functional feeding group, namely phytophagous, zoophagous and omnivorous taxa, with high seasonal variability.Conclusion: Findings highlight the complexity of ecological elements to be taken into consideration for ecologically sound honeybush cultivation. Outcomes can be applied to land management practices and governance policies promoting sustainable agroecosystems in honeybush production areas.

Aspalathus linearis (Burm. F.) R. Dahlgren (Fabaceae) or rooibos, is a strict endemic species, limited to areas of the Cederberg (Western Cape) and the southern Bokkeveld plateau (Northern Cape) in the greater Cape Floristic Region (CFR) of South Africa. Wild rooibos, unlike the cultivated type, is variable in morphology, biochemistry, ecology and genetics, and these ecotypes are broadly distinguished into two main groups, namely, reseeders and resprouters, based on their fire-survival strategy. No previous assessment of genetic diversity or population structure using microsatellite markers has been conducted in A. linearis. This study aimed to test the hypothesis that wild rooibos ecotypes are distinct in genetic variability and that the ecotypes found in the Northern Cape are differentiated from those in the Cederberg that may be linked to a fire-survival strategy as well as distinct morphological and phytochemical differences. A phylogeographical and population genetic analyses of both chloroplast (trnLF intergenic region) and newly developed species-specific nuclear markers (microsatellites) was performed on six geographically representative wild rooibos populations. From the diversity indices, it was evident that the wild rooibos populations have low-to-moderate genetic diversity (He: 0.618–0.723; Ho: 0.528–0.704). The Jamaka population (Cederberg, Western Cape) had the lowest haplotype diversity (H = 0.286), and the lowest nucleotide diversity (π = 0.006) even though the data revealed large variations in haplotype diversity (h = 0.286–0.900) and nucleotide diversity (π = 0.006–0.025) between populations and amongst regions where wild rooibos populations are found. Our data suggests that populations of rooibos become less diverse from the Melkkraal population (Suid Bokkeveld, Northern Cape) down towards the Cederberg (Western Cape) populations, possibly indicative of clinal variation. The largest genetic differentiation was between Heuningvlei (Cederberg, Western Cape) and Jamaka (FST = 0.101) localities within the Cederberg mountainous region, and, Blomfontein (Northern Cape) and Jamaka (Cederberg) (FST = 0.101). There was also a significant isolation by distance (R2 = 0.296, p = 0.044). The presence of three main clusters is also clearly reflected in the discriminant analysis of principal components (DAPC) based on the microsatellite marker analyses. The correct and appropriate management of wild genetic resources of the species is urgently needed, considering that the wild Cederberg populations are genetically distinct from the wild Northern Cape plants and are delineated in accordance with ecological functional traits of reseeding or resprouting, respectively. The haplotype divergence of the ecotypes has also provided insights into the genetic history of these populations and highlighted the need for the establishment of appropriate conservation strategies for the protection of wild ecotypes.

Food insecurity and diet-related diseases do not only have detrimental effects to human health, but are also underpinned by food systems that are environmentally unsustainable and culturally disconnected. Ensuring access to a healthy, affordable, and sustainable diet is one of the greatest challenges facing many low- and middle-income countries such as South Africa. These challenges in accessing a diverse diet often persist despite biocultural richness. For example, South Africa is globally recognised for its rich biodiversity, an ecologically unrivalled coastline, and a rich body of traditional knowledge amongst wild-food users. In this paper, we explore the potential that coastal wild foods as neglected and underutilised species (NUS) can play in local food systems in South Africa’s Western Cape Province. Following a previously established transformation lab (T-Lab) method, here we report the observations and outcomes emerging from a two-day workshop held in May 2019 with a group of 40 actors involved in the local food system in diverse ways. Farmers, small-scale fishers, indigenous knowledge holders, representatives from non-profit organisations, chefs, bartenders, academics, activists, conservationists, and government officials were brought together with the aim of strengthening an emerging coalition of coastal wild food actors. Findings highlighted the existence of a fledgling economy for coastal wild foods, driven by high-end chefs. The T-Lab was essentially a tool of knowledge co-production around food system transformation and helped to surface deeply embedded issues on land, race, history, and culture that warrant engagement if a better food system is to emerge. In a country that is drought prone and vulnerable to climate change, a more resilient and sustainable food system is a necessity. But defining alternative governance systems to shift towards a healthier, more sustainable, and more equitable food system will require concerted effort across all stakeholders.

On 8 June 2020, we, a diverse group of African emerging researchers, published a response to the commentary titled 'Why are black South African students less likely to consider studying biological sciences?' (1) published in the South Africa Journal of Science (SAJS). There are mounting arguments, in both print and social media, regarding the merits of the Nattrass (2020) commentary, particularly around its strong racial undertones as well as poor and unethical research practices. Nattrass' commentary has been intensely divisive, managing to engender stereotypes, anger, and disappointment. Conflicting arguments have emerged, which involve responses by other academics, politicians, and the public, but much of the furore has been strongly biased towards and along racial lines, with very little attention directed at the flawed nature of the research. Such questions as the one asked by Nattrass (1) in the title of the commentary are valid and should be explored. Such research, in fact any research, must involve scientific rigour, robust methodological approaches, sensitivity and adherence to ethical principles. With the right approach and the involvement of multi-sector collaborators, we can begin to innovatively and constructively address the potential societal challenges that may arise. Science should be respected and trusted, and should build a fundamental basis for societal benefits and decision-making processes. Issues of race, whether socially constructed or not (2) are sensitive, and should be treated as such. When dealing with sensitive subjects, it is important to be cognizant of one's inherent unconscious biases. To drive this, scientists, editors, leaders in academia and industry, government research institutions, NGOs and publishers have taken steps to promote ethical conduct in research by signing The Singapore Statement on Research Integrity (3). The Statement was founded on four principles: viz. honesty, accountability, professionalism, and stewardship, which inform the fourteen responsibilities of ethical research conduct. As researchers, it is important that we use these principles and responsibilities to guide our research, and to maintain our responsibilities to each other, to the people and to the environment. For this reason, we wish to express our concern that the Nattrass (2020) commentary and the research contained therein, has violated many of these governing principles. Moreover, in publishing this commentary with all its methodological flaws and ethical problems, the South African Journal of Science (SAJS) has also violated these principles and responsibilities.
