- Description: Accurate and reliable estimation of terrestrial ecosystem degradation is critical to meeting the challenge of reversing land degradation. Remote sensing data (especially land productivity dynamics) is commonly used to estimate land degradation, and this study uses the TRENDS.EARTH toolbox for the period covering 2000–2018, demonstrating the benefit of tracking the degradation process (SDG 15.3.1) at a biophysical unit. Contributing to the country’s SDG 15.3.1 monitoring, anthropogenic degradation was estimated based on RESTREND land productivity, biome-specific land cover trends, and soil organic carbon (SOC) stocks. Underlying degradation was evaluated by reclassifying a 28-year national land cover change dataset to match the UNCCD land cover legend. Analysis results indicate that land productivity changes (especially in stable grasslands, afforested, and cropland areas) mainly influenced the degradation status of the biome (19.9% degraded and 25.6% improvement). Global datasets also suggest that land cover and SOC had a minimal contribution (more than 2%) to anthropogenic degradation dynamics in the biome between 2000 and 2018. The GIS analysis showed that long-term, the major contributors to the biome’s underlying 9% anthropogenic degradation were woody proliferation into the Grassland Biome, urban expansion, and wetland drainage.

- Description: Since 2019, the COVID-19 pandemic has posed challenges to but also highlighted the urgent need for transforming education for sustainable futures. The purpose of this article is to share insights gained from a southern African study on intersecting influences of water, food, livelihoods and education, and what they mean for Education for Sustainable Development going forward. The interest is to learn from this study in ways that can inform transformation of education for sustainable futures in southern Africa going forward. The study involved a number of early career researchers in SADC countries, and was conducted via an online approach during the early days of the pandemic. It followed a qualitative research design, employed document analysis, interviews and questionnaires, and drew on a systems perspective to inform analysis. The findings are as relevant today as they were in the pandemic, and point to the importance of giving attention to intersecting issues that affect education. The study highlights six transformative praxis pathways for transforming education for sustainable futures.

- Description: Increasing human populations and rapid urbanization in sub-Saharan Africa have prompted the development and maintenance of urban green infrastructure, including urban trees for sustainability, human wellbeing, liveability and climate resilience. However, there are still insufficient amounts and large inequities in the distribution of trees between and within towns and cities of the Global North and South. In South Africa, urban green space planning and planting are encoded in several policies at national level. However, these policies are rarely translated into specific guides, standards or actions, and consequently disparities in urban trees and green space distribution persist. This study assessed the prevalence of urban trees in domestic gardens in low-cost housing areas (LCHAs) of eight small to medium-sized towns in the Eastern Cape province of South Africa and examined residents’ perceptions in this regard. This was done via surveys with 800 households in old and recently developed LCHAs. The results revealed that most households (52 %) had at least one tree in their yard, with more households in the older neighbourhoods (60 %) reporting having trees than in the newer ones (44 %). Most of the trees (66 %) had been deliberately planted as opposed to natural regeneration. Experience of formal urban tree planting programs was low, but 75 % of residents expressed willingness to participate in the future, preferably in tree planting and maintenance. Urban green spaces and trees cannot be an afterthought in the development of sustainable human settlements, and municipal plans should reflect tangible commitments in this regard. Meeting goals for greener LCHAs requires the involvement of local residents, and for municipal authorities to be receptive to the wishes of residents and willingness to green their residential areas.

- Description: In this work, the preparation of glucose encapsulating nanoliposomes was achieved using two different lipid formulations, labelled as F1 and F2. Both formulations contained phosphatidylcholine (PC), oleylamido-4-butanoic acid (OABA) and in addition, F1 had cholesterol (CHO) while F2 contained cholesteroyl hemisussinate (CHEMS). These formulations were studied for their pH sensitivity and controlled release of encapsulated glucose for indirect detection of prostate-specific antigen (PSA) using sandwich immunoassay. As a signal generator, encapsulated glucose in nanoliposomes was quantified directly using the personal glucose meter (PGM) and colorimetrically using peroxidase property of horseradish peroxidase (HRP) enzyme and Pd|PdO as nanozymes. Controlled release of the encapsulated glucose was achieved using the pH effect or Triton-X 100 as a surfactant to destabilize the liposomal structure. The F2 formulation showed maximum controlled release at acidic phosphate buffer saline (PBS, pH 5.0). The concentration of encapsulated glucose was found to be high in F2 formulation and these were applied for the indirect detection of PSA. The limit of detection (LOD) values for PSA were found to be 53 fg mL−1, 64 fg mL−1 and 10 fg mL−1 when HRP, Pd|PdO and PGM were respectively used. The detection signal was linear over a wide concentration range for PSA including the clinical range of 4–10 ng mL−1. The HRP system showed low LOD value when compared with Pd|PdO nanozymes. PGM system gave lowest LOD values owing to the sensitivity of the system towards glucose. Pd|PdO nanozyme system showed good stability over a wide temperature up to 80 °C. PGM system required less reaction time (2 min), low reagents and results were readily generated in digital format.

- Description: Much previous research has problematized the use of a binary urban–rural distinction to describe human settlement patterns in and around cities. Peri-urban zones, on the edge of urban settlements, are important both in the sheer magnitude of human population and in terms of being home to vulnerable populations with high rates of poverty. This Perspective presents a framework that conceptualizes rural–urban transition through the prism of shifts in natural, engineered and institutional infrastructure to explain the processes of rapid change and the dip in service provision often found in peri-urban areas in the Global South. We draw on examples related to the provision of water and sanitation to illustrate the theory and discuss its implications for future research on the peri-urban. A research agenda is set out that emphasizes the importance of studying early warning signs of service dips using systems theory concepts such as flickering and critical slowing down. Through such approaches, research can better predict and explain what we call peri-urban turbulence and inform the development of mitigation strategies to reduce the vulnerabilities that peri-urban residents too often face during periods of rural–urban transition.

- Description: Background/Objective: The most recent versions of the two main mental disorders classifications—the World Health Organization's ICD-11 and the American Psychiatric Association's DSM–5—differ substantially in their diagnostic categories related to transgender identity. ICD-11 gender incongruence (GI), in contrast to DSM-5 gender dysphoria (GD), is explicitly not a mental disorder; neither distress nor dysfunction is a required feature. The objective was compared ICD-11 and DSM-5 diagnostic requirements in terms of their sensitivity, specificity, discriminability and ability to predict the use of gender-affirming medical procedures. Method: A total of 649 of transgender adults in six countries completed a retrospective structured interview. Results: Using ROC analysis, sensitivity of the diagnostic requirements was equivalent for both systems, but ICD-11 showed greater specificity than DSM-5. Regression analyses indicated that history of hormones and/or surgery was predicted by variables that are an intrinsic aspect of GI/GD more than by distress and dysfunction. IRT analyses showed that the ICD-11 diagnostic formulation was more parsimonious and contained more information about caseness than the DSM-5 model. Conclusions: This study supports the ICD-11 position that GI/GD is not a mental disorder; additional diagnostic requirements of distress and/or dysfunction in DSM-5 reduce the predictive power of the diagnostic model.

- Description: In keeping with the 2021 IACR Conference theme (Re) Envisaging Emancipatory Research, Science and Practice, this paper reviews over fifty instances of critical realist research in Africa which have sought to establish emancipatory research praxis by using critical realism to underlabour a range of applied studies in a diversity of disciplines and countries. The initiators of this research have been drawn to critical realism for several reasons, most notably its return to ontology, its interest in transformed, transformative praxis, and its potential for addressing knowledge and experiences exclusions. The paper ends with a reflection on ‘What's in a Conference Theme', returning to the earlier 2012 IACR conference hosted in Africa, and the 2021 conference’s focus on emancipatory research. It argues both for the deepening of conversations between critical realism and Africana Critical Theory; and for the grounding of these conversations in the voices and power of the people in our communities

- Description: In South Africa there has been relatively little consideration of the informal employment offered to domestic household workers and gardeners. Here we report on the number and profile of gardeners employed by private households and the wage and satisfaction rates in 12 towns of the Eastern Cape. Over 98% of the informal gardeners were male, middle-aged and with limited formal schooling. Approximately 58% of middle and upper income households employed a gardener, at a mean daily rate of R112.20 in 2019. This equated to 13 170 gardeners earning a total wage bill of R139 million p.a. across the 12 towns, which scales up to 0.7–1 million informal gardeners nationally earning approximately R10–14 billion per year. However, daily remuneration was insufficient to cover basic needs, and slightly more than half of the gardeners would prefer a different job, indicating the survivalist nature of the sector.

- Description: This article gives a snapshot view of how Mmusi Maimane’s rise to leadership in the Democratic Alliance (DA) in 2015 was reported on in the Daily Sun, South Africa’s biggest-selling national daily newspaper (South African Audience Research Foundation, 2016). Through analysis of a Daily Sun news article exemplifying trends in the positioning of the DA in the tabloid over the first half of 2015, the present study demonstrates how Maimane tried to align the DA around a new iconography (Tann 2010, 2013), centred on the values of “freedom”, “fairness” and “opportunity”. Moreover, the present study also shows how this purported transformation in the DA was treated with scepticism by the news article’s author, who iconizes the DA as incapable of transformation and effective governance. Fine-grained complementary Legitimation Code Theory (LCT) and Systemic Functional Linguistics (SFL) analyses were conducted on this news article. The LCT analysis shows how multiple voices in the news article create conflicting binary constellations, axiologically charged through various linguistic resources, including intertextual references. The analysis, using SFL’s Appraisal system (Martin and White 2005), shows how iconization is accomplished in the news article through evaluative language, coupled with intertextual references, grammatical metaphor andtechnicality to produce syndromes of meaning in the news article. Such iconization works, in this case, to reproduce an attitude of cynicism toward party politics in post-apartheid South Africa. This cynicism foreshadows Maimane’s ultimate lack of success in transforming the discourses of the DA.

- Description: This article gives a snapshot view of how Mmusi Maimane’s rise to leadership in the Democratic Alliance (DA) in 2015 was reported on in the Daily Sun, South Africa’s biggest-selling national daily newspaper (South African Audience Research Foundation, 2016). Through analysis of a Daily Sun news article exemplifying trends in the positioning of the DA in the tabloid over the first half of 2015, the present study demonstrates how Maimane tried to align the DA around a new iconography (Tann 2010, 2013), centred on the values of “freedom”, “fairness” and “opportunity”. Moreover, the present study also shows how this purported transformation in the DA was treated with scepticism by the news article’s author, who iconizes the DA as incapable of transformation and effective governance. Fine-grained complementary Legitimation Code Theory (LCT) and Systemic Functional Linguistics (SFL) analyses were conducted on this news article. The LCT analysis shows how multiple voices in the news article create conflicting binary constellations, axiologically charged through various linguistic resources, including intertextual references.

- Description: Methyltin(IV) of butyltin(IV)–N-hydroxyethyl dithiocarbamate complexes, represented as [(CH3)2Sn(L(OH))2] and [(C4H9)2Sn(L(OH))2] respectively were synthesized and characterized using spectroscopic techniques (1 H, 13C and 119Sn NMR) and elemental analysis. Both infrared and NMR data showed that, the complexes were formed via two sulphur atoms of the dithiocarbamate group. This mode of coordination was further supported by the DFT calculation, which suggested the formation of a distorted octahedral geometry around the tin atom. The complexes were screened for their antioxidant, cytotoxicity and anti-inflammatory properties. Four different assays including DPPH, nitric oxide, reducing power and hydrogen peroxides were used for the antioxidant studies, while an in vitro anti-inflammatory study was done using albumin denaturation assay. The complexes showed good antioxidant activity, especially in the DPPH assay. Butyltin(IV)–N-hydroxyethyl dithiocarbamate showed better cytotoxicity activity compared to methyltin(IV)–N-hydroxyethyl dithiocarbamate in the selected cell lines, which included KMST-6, Caco-2 and A549 cell lines. The anti-inflammatory activities revealed that the two complexes have useful activities better than diclofenac used as control drug

- Description: This study determined the chemical composition of essential oil obtained from fresh leaf of Plectranthus aegyptiacus, and evaluated it for novelty-induced behavioural (NIB) and determine its mechanism(s) of action in mice. The oil was hydro-distillated, and analyzed using gas chromatography-mass spectrometry. The effects of the oil (50, 100 and 150 mg/kg; i.p., n=6) on novelty-induced behavioural was assessed using open field test and head dipping on hole board. Probable mechanism(s) were evaluated using antagonists: flumazenil, naloxone and cyproheptadine at 2 mg/kg each, atropine and yohimbine at 5 mg/kg and 1 mg/kg respectively. The LD50 values obtained were 2154 and 490 mg/kg for oral and intraperitoneal routes respectively. The oil (50, 100 and150 mg/kg) significantly (p less 0.05, 0.01 and 0.01) inhibited all NIB and head dips. Flumazenil significantly (p less than 0.05) reversed the effect of the oil on NIB; atropine, naloxone and cyproheptadine significantly (p less than 0.01, 0.01 and 0.001) potentiated inhibitory effect on NIB respectively, while yohimbine showed no significantly effect. The analyzed oil showed 61 compounds, and the major compounds were carvacrol, germacrene-D, p-cymene and [1,1'-Bicyclopentyl]-2,2'-diol. The study concluded that the oil possessed central nervous system depressant activity, which could be mediated mainly through augmentation of GABAergic neurotransmission, while cholinergic-(muscarinic), adrenergic and serotonergic pathways may be involved.

- Description: Introduction: This case report discusses the successful use of an improvised bubble continuous positive airway pressure (CPAP) apparatus made using items commonly available in a poorly resourced district hospital. Case presentation: A 64-year-old female with no co-morbidities presented with respiratory failure due to pulmonary tuberculosis and was not accepted into the regional Intensive Care Unit (ICU) on referral. She required 8 days of improvised bubble CPAP to maintain adequate oxygen saturation before weaning and eventual discharge. Discussion: Improvised bubble CPAP is commonly used in neonatal care in developing countries and well described in literature however, there are no reports of its successful use in adult patients. In the absence of access to ICU or other Non-invasive ventilation (NIV) equipment, improvised bubble CPAP may provide some therapeutic benefit.

- Description: Studies of projected agro-climatic variability on the productivity of smallholding farming livelihoods have been evaluated by indirect methods using simulation models on country or regional basis but few have been done at the community level. This study explores direct observation of the impact of soil and climate factors on crop and livestock livelihood systems in the three major agro-ecological zones of the Eastern Cape Province of South Africa. It also analyzed their influence on small farmers’ choices of agrarian livelihood activities and the lessons learned for the suitability of agro-ecologically integrated agriculture as part of agrarian and food security reforms needed among small farming households in rural communities of South Africa. The impact of soil and rainfall on the crop and livestock livelihood choices of smallholders in the three major agro-ecological zones were explored. A cross-sectional survey was carried out among 223 smallholding farming households during the harvesting period of rain-fed farming season. Data on household livelihood activities were processed in monetary terms and subjected to gross margin and cost/benefit analysis. Geographic information system (GIS) mapping and statistical analysis were used to determine the association of smallholder maize revenue with agro-climatic variation. The results indicated that crop-based activities performed better in the Grassland zone, while livestock activities performed better in the Savanna zone. Small farms in the Karoo can only productively engage in livestock production. The results also showed that farming activities that combined more vegetable crops yielded greater profits than other field crops. Furthermore, the results indicate that the mixed cropping method remains one of the strategies for breaking-even and risk-bearing effort used by the smallholder farmers considering its cost-sharing benefits. Geographical information system (GIS) mapping further indicates that smallholders’ farming activity was not only affected by soilclimatic factors but by their management skills as well. We recommend agroecologically adapted policies and incentives for agriculture-based livelihood activities and intensified mixing of cropping systems among the smallholder farming households in the study area.

- Description: The Covid-19 pandemic and the associated lockdown regulations suddenly elevated the importance of blended learning in South Africa and worldwide. This has prompted various international and national institutions into action, providing various support services to enhance fast digital adoption in higher education and facilitate out of classroom learning. In this regard, this paper views the pandemic as a necessary evil that can catalyse the adoption of digital learning, particularly, in rural-based universities of South Africa that have been lagging in the digital education front. The paper reviews recent literature and document opportunities that are emerging from the Covid-19 pandemic. These opportunities can assist rural-based universities to sustainably adopt blended learning, catch up with the elite universities, and bridge the digital divide that is still apparent in South Africa. The paper is based on a review of articles, educational policy documents, and government gazettes. The Atlasti version 8 software was utilised to synthesise the literature. It was concluded that various opportunities exist for rural-based universities. To enhance effective digital transformation in rural-based universities, there is a need for alignment of national policy with realities in different institutions, improve human digital apprehension capacity, and increase collaborations between education technologists and education institutions as well as behavioural change among higher education managers. These changes can enable rural-based universities to build on the opportunities presented by the pandemic and digitalise their education programs to align with the inevitable demands of the 4th industrial revolution.

- Description: Assumptions and facts exist about the various challenges rural learners face when transitioning into university education in South Africa due to the pedagogical differences between secondary and university education. However, the advent of the COVID-19 pandemic compounded the transitioning challenges of students because most of the universities, especially the selected university, utilise online learning, which is alien to first-year students who are transitioning from rural high schools to the university. This study explores the challenges and solutions associated with first-year students transitioning to a new level of education during the COVID-19 pandemic. An asset-based approach was used to theorise the study within the Transformative Paradigm (TP), while Participatory Research (PR) was used to design the study. These are relevant because both TP and PR are targeted towards transforming people’s predicaments. The participants consisted of ten first-year students selected using a convenient sampling technique. Data was collected using electronic interviews such as email, WhatsApp messages, and phone calls. The data were analysed using thematic analysis. The study revealed that first-year rural university students’ inability to use online learning tools effectively and unstable internet connections in the rural community are major challenges. The study, therefore, concludes that the provision of internet access and students’ readiness for adaptability are the possible solutions.

- Description: Background. Medical doctors in South Africa (SA) are required to complete a 2-year internship at training hospitals, including a 4-month rotation in obstetrics and gynaecology. Following this, doctors are allocated to community service posts, many of which are at district- and primary-level facilities where supervision is limited. Recent triennial Saving Mothers reports identify district hospitals (DHs) as the second leading site for maternal deaths of all causes, the leading site for maternal deaths secondary to obstetric haemorrhage, and the most likely site for the lack of a skilled doctor to be identified as a factor in deaths associated with caesarean delivery. Objectives. To describe the self-perceived readiness of medical interns completing their training to manage obstetric emergencies, based on the Essential Steps in the Management of Obstetric Emergencies modules in the Health Professions Council of South Africa’s internship logbook. Methods. This cross-sectional descriptive study assessed medical interns in the last 3 months of their training, using a self-administered online questionnaire. Data collection took place between October and December 2019. Results. Cluster sampling of interns at training facilities throughout SA resulted in a total of 182 respondents from 17 hospitals in seven provinces in the country, with an overall response rate of 34.1%. Most interns had experience with and confidence in the management of miscarriage and hypertension in pregnancy. However, gaps in labour ward management, pregnancy-related sepsis and surgical skills were identified. Only 42.3% of respondents were confident in their ability to diagnose obstructed labour, 26.3% had performed an assisted delivery, 39.0% were confident in their knowledge of the indications for and contraindications to assisted deliveries, and 35.7% had been involved in the delivery of a baby with shoulder dystocia. Regarding pregnancy-related sepsis, 54.4% had experience with managing a wound abscess and 29.7% were confident managing puerperal endometritis. While 78.0% felt confident to perform a caesarean section (CS), only 28.6% had performed uterine compression suture for uterine atony at CS. Additionally, there was a statistically significant variation in scores between training hospitals. Conclusions. An incongruity exists between the shortcomings in DH obstetric services, the prioritisation of placement of community service doctors at primary healthcare facilities and DHs, and the self-perceived readiness of medical interns completing their training to manage obstetric emergencies safely. This situation highlights the importance of clinical support for junior doctors at DHs and standardisation of intern training at accredited facilities across SA.

- Description: Whilst citizens are at liberty to decide whether or not to report a crime to the police, nonreporting of crime to the police may come with a heavy price. This study evaluates the consequences of non-reporting of crime to the police in South Africa’s Mthatha policing area. It comes against a backdrop of a rise in criminal activities in South Africa. A survey was conducted among households in selected residential areas of Mthatha, from where 120 respondents were selected through stratified random sampling technique. Data analysis was done using SPSS to reveal both descriptive and inferential statistics. From the analysis, continued engagement in criminal activities by perpetrators, resulting in absence of investigations was found to be the major impact of non-reporting of crime to the police. Findings also revealed that the victims bear the most implications of non-reporting of crime. Inability to identify crime hot spots, misallocation of policing resources and inability to determine crime trends and tendencies were also viewed as significant impacts of non-reporting of crime to the police. A factor analysis revealed officials’ inability to determine trends and tendencies that could inform policing strategies as the most significant component.

- Description: There are many women survivalist entrepreneurs in South Africa, many of whom work in the informal sector. The emergence of theCOVID-19 pandemic has a devastating effect on their entrepreneurial projects. While both the public and private sectors have initiated various measures to ease the blow, obstacles continue to confront them. This study sought to examine the challenges faced by women survivalist entrepreneurs in South Africa’s Johannesburg metropolitan area. The researchers gathered qualitative data using a qualitative research approach by conducting semi-structured face-to-face interviews. The data was analysed using thematic analyses. The themes that emerged from the findings include; a lack of capital for reinvestment, no government grant support, a decline in the demand for products by the market, rotting agricultural produce or stock, a battle for strategic selling points and numerous confrontations with police as a result of not meeting the regulatory rules relating to COVID-19. The present research provides theoretical implications for academics in entrepreneurship by enhancing the understanding of the hurdles that these entrepreneurs have experienced because of COVID-19. On the practitioners’ side, this work offers avenues for women survivalist entrepreneurs to improve their entrepreneurial ventures and eventually eliminate the challenges they face when running their ventures. This study also offers policy implications. For example, existing government policies can be amended to make the working conditions of women survivalist entrepreneurs better or make the rules under which they operate simpler. This study contributes to entrepreneurship literature by uncovering the difficulties faced by women survivalist entrepreneurs due to the COVID-19 pandemic. It will assist other scholars in further developing this research field. As such, this research is important for women survivalist entrepreneurs because most of them endeavour to enhance entrepreneurial performance for the betterment of their lives. Governments may also use the study to develop interventions aimed at facilitating the growth and development of women survivalist entrepreneurs.

- Description: This paper provides an analysisof the risk factors that make South African Police Services officers vulnerable to becoming victims of crime. The participants of this study comprise of one hundred and five (105) male and female police officers of various demographics, randomly selected from nine (9) police stations. The study utilised survey instrument (questionnaire) to collect data from the respondents, which were analysed by employing relevant descriptive and inferential tools from Statistical Package forthe Social Sciences. Even though this study found work related factors and new rank as predisposing conditions for victimization, police officers were found to be more susceptible to victimization due to going out atnight alone, staying out at nights generally and indulgence in alcoholism. While living in descriptively, ‘bad area’ and crime prone areas were potent factors to police officers being victimised, carrying firearms never saved them from attacks. Interestingly, police officers with 1-5 years of experience who are married have greater victimization experience than those who never married, across all police stations.

- Description: Much has been written on the scourge of human trafficking, with majority of previous research focussing on trends, forms, as well as the regulatory framework for countering the scourge. Despite the presence of a vast body of knowledge on human trafficking, less attention has been given to the operational dynamics that are involved in the investigation and prosecution of human trafficking cases. This paper, which is based on a literature and documentary survey, evaluates the challenges that are encountered by the criminal justice players in responding to human trafficking. The paper specifically focuses on the challenges that are faced by law enforcement agencies in the investigation of human trafficking, as well as the challenges that are faced in the prosecution of human trafficking offenders. Whilst the paper takes a global approach to the problem, much attention is given to South Africa and Zimbabwe- two neighbouring Southern African nations. Keywords: human trafficking, investigations, prosecution, victim protection
