- Description: This chapter develops a framework for design considerations that can be used to analyze, contrast, and design networked professional development (NPD) in higher education (HE) contexts. The framework was developed after reflecting on three professional development (PD) courses, each with facilitators who are academic developers across the African continent. Using a Collaborative Autoethnographic methodology, the three authors reflect on design considerations for different forms of blended and online PD courses, based on their experiences of designing and/or facilitating these interventions and with PD more broadly. We argue that course designs can be positioned along a range of dimensions, namely open/closed, structured/unstructured, facilitated/unfacilitated, certified/uncertified, with/without date commitments, homogenous versus autonomous learning path, content vs. process centric, serious vs. playful, and individual vs. collaborative. We discuss relationships between dimensions and learning theories (the more open dimensions speak to connectivist, while more structured courses follow social constructivist approaches). We also identify various tensions that arise in the design of NPD, such as between academic developers’ pedagogical advocacy vs. usefulness, need to maintain volunteerism without exploitation of affective labour, and struggle to create spaces for agency within institutional constraints.

- Description: The dimeric dihydropyrimidine dehydrogenase (DPD), metalloenzyme, an adjunct anti-cancer drug target, contains highly specialized 4 × Fe2+4S2−4 clusters per chain. These clusters facilitate the catalysis of the rate-limiting step in the pyrimidine degradation pathway through a harmonized electron transfer cascade that triggers a redox catabolic reaction. In the process, the bulk of the administered 5-fluorouracil (5-FU) cancer drug is inactivated, while a small proportion is activated to nucleic acid antimetabolites. The occurrence of missense mutations in DPD protein within the general population, including those of African descent, has adverse toxicity effects due to altered 5-FU metabolism. Thus, deciphering mutation effects on protein structure and function is vital, especially for precision medicine purposes. We previously proposed combining molecular dynamics (MD) and dynamic residue network (DRN) analysis to decipher the molecular mechanisms of missense mutations in other proteins. However, the presence of Fe2+4S2−4 clusters in DPD poses a challenge for such in silico studies. The existing AMBER force field parameters cannot accurately describe the Fe2+ center coordination exhibited by this enzyme. Therefore, this study aimed to derive AMBER force field parameters for DPD enzyme Fe2+ centers, using the original Seminario method and the collation features Visual Force Field Derivation Toolkit as a supportive approach. All-atom MD simulations were performed to validate the results. Both approaches generated similar force field parameters, which accurately described the human DPD protein Fe2+4S2−4 cluster architecture. This information is crucial and opens new avenues for in silico cancer pharmacogenomics and drug discovery related research on 5-FU drug efficacy and toxicity issues.

- Description: Some dihydrobenzo[4,5]imidazo[1,2-c]quinazolines have been synthesized from aldehydes and ketones, using the ketones as both reagents and solvents and tetrahydrofuran (THF) as the solvent for the aldehydes, to yield the triazatetracyclics. The compounds have been characterized with spectroscopy and microanalysis. The crystal structures of 9,9-dimethyl-8,10,17- triazatetracyclo[8.7.02,7.011,16]heptadeca-1(17),2,4,6,11(16),12,14-heptaene (I), 9-butyl-9-methyl-8,10,17-triazatetracyclo[8.7.0.02 , 7 .011,16]heptadeca-(17),2,4,6,11(16),12,14-heptaene (III) and 9-phenyl-8,10,17-triazatetracyclo[8.7.0 02 7.011,16] heptadeca-1(17),2,4,6,11(16),12,14-heptaene (VIII) have been discussed. The computed NMR, IR, molecular electrostatic potential and frontier molecular orbitals of compounds I, III and VIII have been discussed. The M06 functional gave most of its values closest to the experimental values for the bond lengths and bond angles of compounds I and III. For compound VIII, none of the functionals gave values for bond lengths and bond angles that were consistent with the experimental values, but M06 gave values closest to experimental values. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) scavenging activity of the triazatetracyclics showed that compound I exhibits signifcant DPPH scavenging activity with an IC50 of 56.18 µM compared to 2.37 µM for ascorbic acid.

- Description: Urban ecology is a key discipline in guiding urban development, sustainability and consequently human wellbeing. However, most urban ecological research has, and continues to be, undertaken in the Global North, and thus urban ecological methods, principles and frameworks are dominated by contributions and understandings from the Global North. However, there are a multitude of local- and national-scale contextual differences between the Global North and the Global South that limit or question the universal application of Global North perspectives and knowledge. This chapter lays the foundation for the rest of the book in two ways. First, it explores the development and definitions of the terms ‘urban ecology’ and ‘Global South’. Second, it presents the major biophysical and socio-economic contextual characteristics of Global South towns and cities that differentiate them from those in the Global North. These contextual differences need to be accounted for in urban ecological research, theory and application towards the development of an urban ecology that is more relevant for the Global South, and when conjoined with understandings from the Global North allow for the exploration and development of truly universal urban ecology principles and frameworks.

- Description: Globally, almost one billion people are estimated to face hunger on a regular basis (Poppy et al., 2014) and more than two billion people suffer from micronutrient deficiencies (Barrett, 2010; FAO et al. 2020). The number of food-insecure people has been on the rise with subSaharan Africa having the greatest number of individuals who are both hungry (about 237 million people) and malnourished (almost 23% of the population) (FAO, 2018). Beyond hunger, FAO et al. (2020) noted that a growing number of people have had to reduce the quantity and quality of the food they consume. This makes it almost impossible to have a world with zero hunger by 2030 and achieve SDG 2 target 2.1 of ensuring access to safe, nutritious and sufficient food for all people and target 2.2 of eradicating all forms of malnutrition (UN 2015). Most governments globally have pledged to eradicate hunger in their nations by 2030, and one of their solutions is to increase agricultural productivity to meet the needs of all their people. However, Poppy et al. (2014) argued that increased yields and food supplies do not assure food security for all as some poorer societies and communities may not have access to sufficient quantity or quality food (Iram and Butt, 2004), which is a challenge in many African communities, especially in South Africa. This highlights the complexity of the food system within many countries.

- Description: Against the background of unprecedented rates of urbanisation in the Global South, leading to massive social, economic and environmental transformations, this book engages with the dire need to understand the ecology of such settings as the foundation for fostering sustainable and resilient human settlements in contexts that are very different to the Global North. It does so by bringing together scholars from around the world, drawing together research and case studies from across the Global South to illustrate, in an interdisciplinary and comprehensive fashion, the ecology of towns and cities in the Global South. Framed using a social-ecological systems lens, it provides the reader with an in-depth analysis and understanding of the ecological dynamics and ecosystem services and disservices within the complex and rapidly changing towns and cities of the Global South, a region with currently scarce representation in most of the urban ecology literature. As such the book makes a call for greater geographical balance in urban ecology research leading towards a more global understanding and frameworks. The book embraces the complexity of these rapid transformations for ecological and environmental management and how the ecosystems and the benefits they provide shape local ecologies, livelihood opportunities and human wellbeing, and how such knowledge can be mobilised towards improved urban design and management and thus urban sustainability.

- Description: As much as people benefit from the ecosystem services provided by nature, ecosystem disservices also impact daily lives. This is especially true for many urban communities in the Global South due to (1) the often greater diversity of ecosystem disservices and (2) higher vulnerabilities, which together can lead to greater impacts of ecosystem disservices in many Global South settings. This chapter provides an overview of the current understandings of urban ecosystem disservices and their assessment and management with an emphasis on the Global South, albeit with reference to the Global North where useful. This overview reveals a lack of detailed and systematic empirical research on urban ecosystem disservices generally, but even more so in the Global South, despite the greater diversity and vulnerability in Global South settings. This needs to be acknowledged in urban ecology framings of urban dynamics in the Global South and translated into better integration of both ecosystem services and disservices within common research, policy or management frameworks. It is only through such integration that appropriate context-relevant policy directions and management options can be identified, thereby promoting the wellbeing of urban citizens in the Global South.

- Description: In the present study, we evaluated the phytochemical compounds and antioxidant properties of chloroform, ethanol and acetone extracts for leaves and flowers of Leonutus leonurus (L. leonurus) alongside with their cytotoxic effects on human cervical carcinoma (HeLa) cell lines. The phytochemical compounds present in the leaves and flowers of L. leonurus included; phenolics, flavonoids and alkaloids. Their radicals scavenging effects against 2, 2-diphenyl-1-picrylhydrazyl [DPPH] 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulphonate) [ABTS·+], hydrogen peroxide, nitric oxide as well as metal chelating activities showed dose-dependent activities. Gas chromatography-mass spectrometry (GCMS) analyses revealed the presence of important bioactive compounds, which are associated with antioxidant; and the extracts exhibited toxicity effect against HeLa cells. The findings from this study divulge extracts of L. leonurus as prospective sources of antioxidant and anticancer agents; and hence, further study on their neuroprotective potentials becomes imperative.

- Description: Prevailing approaches to the structural challenges of Corporate Social Responsibility (CSR) tend to be monolithic and skewed towards CSR at the organisational level. Albeit, mirroring CSR at the organisational level with activities of practitioners at the social level can offer new reflexive approaches for identifying capabilities for and understanding thresholds of social learning. This chapter maps out how identity perspectives to CSR can offer new approaches for surfacing emergent properties inherent in the uptake of CSR institutionally and in practice. The chapter also presents an overview of the interplay be-tween structure and agency (prescribed and actual CSR practices) and its underlying in-strumental role for illuminating systemic factors which perpetuate such capabilities and thresholds. Using a morphogenetic theo-ry of change, the chapter offers a framework for approaching CSR-based corporate identity. Empirical evidence from the applied framework is thereafter presented, in the context of the agro-processing industry based on a content analysis of an-nual reports, in-depth-interview data generated from four sus-tainability managers and corporate communication officers and the practices of extension and Local Economic Development (LED) officers. The framework demonstrates that companies with a disintegrated CSR identity inherently have more capaci-ty to be change agents.

- Description: Prevailing approaches to the structural challenges of Corporate Social Responsibility (CSR) tend to be monolithic and skewed towards CSR at the organisational level. Albeit, mirroring CSR at the organisational level with activities of practitioners at the social level can offer new reflexive approaches for identifying capabilities for and understanding thresholds of social learning. This chapter maps out how identity perspectives to CSR can offer new approaches for surfacing emergent properties inherent in the uptake of CSR institutionally and in practice. The chapter also presents an overview of the interplay be-tween structure and agency (prescribed and actual CSR practices) and its underlying in-strumental role for illuminating systemic factors which perpetuate such capabilities and thresholds. Using a morphogenetic theo-ry of change, the chapter offers a framework for approaching CSR-based corporate identity. Empirical evidence from the applied framework is thereafter presented, in the context of the agro-processing industry based on a content analysis of an-nual reports, in-depth-interview data generated from four sus-tainability managers and corporate communication officers and the practices of extension and Local Economic Development (LED) officers. The framework demonstrates that companies with a disintegrated CSR identity inherently have more capaci-ty to be change agents. Similarly, a strong corporate heritage identity is not indicative of a reciprocal link between espoused values and activity. Conversely, an enduring corporate herit-age identity may not necessarily be improvisatory for social learning. In conclusion, the chapter gives an overview of a tax-onomy of agential capabilities and associated cognitive re-sources inherent in the interaction between structural-cultural and personal emergent properties, which can initiate the posi-tioning of social learning at the forefront of organisational de-liberations.

- Description: This chapter takes the reader into the context of rural South Africa with a sketch of developmental and educational chal-lenges from the point of view of a young person born here. It goes on to ask whether Eco-Schools has a role in this chal-lenging context, as a vehicle for or form of Education for Sus-tainable Development (ESD). Past Eco-Schools evaluations are reviewed against current educational needs and livelihood opportunities. The findings suggest that Eco-Schools gives teachers greater environmental awareness and motivates pedagogical practices such as active learning in relation to lo-cally relevant issues. Learners develop environmental com-mitment and a sense of agency, and may become more com-mitted to academic learning – all of which is necessary to pre-pare them for thriving in and also improving their socio-ecological contexts. Eco-Schools further supports schools sys-temically through meaningful partnerships with external agen-cies. The conclusion is that attempts should be made to scale up and scale out this impact. In the process, key features of the programme should be preserved. These include a focus on sustainable solutions.

- Description: Sedimentation arising from agricultural run-offs, riparian habitat fragmentation and channel bank erosion has long been known to impair the structure and ecological functioning of stream and river ecosystems. This study examined the effects of fine sediment grain sizes on the functional feeding group structure of Ephemeroptera, Plecoptera and Trichoptera (EPT) in the Tsitsa River catchment in the Eastern Cape Province of South Africa. Fine sediments and EPT were sampled between August 2016 and April 2017 from eight selected sampling sites. The eight sites were classified into four groups in terms of fine sediments and turbidity to represent a gradient of sediment stress, with site groups 4 and 3 being less influenced and groups 2 and 1 as the highly influenced groups. EPT genera/species were assigned to five functional feeding groups (FFGs) and their responses to sediment stress assessed.

- Description: This chapter examines current knowledge relating to the human and social dimensions of biological invasions in South Africa. We do so by advancing 12 propositions and examining the evidence for or against each using South African literature. The propositions cover four broad issues: how people cause invasions; how they conceptualise them; effects of invasive species on people; and peoples’ responses to them. The propositions we assess include:(1) intentional introductions were and continue to refiect the social ethos of the time;(2) people go to great lengths to ensure that newly introduced species establish themselves;(3) human-mediated modifications help invasive species to establish;(4) how people think about and study invasive species is strongly shaped by social-ecological contexts;(5) knowledge and awareness of invasive species is low amongst the general public;(6) personal values are the primary factor affecting perceptions of invasive alien species and their control;(7) specific social-ecological contexts mediate how invasive species affect people;(8) research on social effects of invasive species primarily focuses on negative impacts;(9) the negative social impacts of invasive species on local livelihoods are of more concern to people than impacts on biodiversity;(10) people are less willing to manage species regarded as ‘charismatic’;(11) social heterogeneity increases confiicts around the management of biological invasions; and (12) engagement with society is key to successful management. By advancing and questioning propositions, we were able to determine what is known, provide evidence for where gaps lie, and thus identify areas for future research.

- Description: A trial and error venture at beekeeping by Arnold Kasumbu in central Malawi, is now a successful integrated farming enterprise incorporating 160 beehives and producing honey for customers in Malawi and Kenya. It is also a site for educational visits for university students learning about agriculture. Arnold’s parents were tobacco farmers living in the Mitundu area of Lilongwe District in central Malawi. He recalls that his childhood was steeped in poverty as he observed his father put in a lot of effort in his farm with diminutive returns. Being the eldest of three children in the household, Arnold was forced to end his schooling in Standard 8, as his family could not afford the school fees. Resolving that he would not do tobacco farming, he began exploring other means of income generation that would entail fewer struggles. He wanted to become wealthy and take care of his family. Through his integrated farm and beekeeping, he has done exactly that! This is Arnold’s life story.

- Description: Thiazoles have shown a broad range of biological activities and are found in many potent biologically active molecules such as Sulfathiazol (antimicrobial drug), Ritonavir (antiretroviral drug), Abafungin (antifungal drug), and Tiazofurin (antineoplastic drug) [1]. They have exhibited some degree of plant growth regulatory and antifungal activities [2], whilst some thiazoles have shown anti-infective [3] as well as antibacterial activities [4]. The regio-controlled synthesis of 2,5-disubstituted and 2,4,5-trisubstituted thiazoles from ethyl-2-bromo-5-chloro-4-thiazolecarboxylates using sequential palladium-catalyzed coupling reactions has been reported [5]. An efficient general method for the preparation of 2,4-di- and trisubsituted thiazoles is via P–TsOH. H2O-Catalyzed cyclization of trisubstituted propargylic alcohols with thioamides has been accomplished with moderate to excellent product yields under mild and standard conditions [6]. In the presence of triethylamine, (Z)-(2-acetoxyl-1-alkenyl) phenyl-λ3 iodanes reacts with thioureas or thioamides in methanol to afford 2,4- disubstituted thiazoles in good yields. The reaction is thought to proceed by the generation of highly reactive α-λ3 iodanyl ketones through ester exchange of the β-acetoxy group with liberation of methyl acetate, followed by nucleophilic substitutions with thioureas or thioamides [7].

- Description: The debates around the value and importance of non-timber forest products (NTFPs) are complex and ongoing. The complexity is a result of many factors, including the wide variety of species, products and uses, as well as the variety of constituencies and disciplines each seeing advantage from ‘co-opting’ the importance of the contribution of NTFPs to their own areas of interest and concern. Conservationists are interested in NTFPs because their combined high value in many settings offers a potential alternative to the destruction of forests by either commercial logging or their widespread conversion to other land uses.

- Description: This book has sought to contribute to the policy and academic debates regarding the opportunities and usefulness of the NTFP sector in reducing poverty. We have argued in the opening chapters that it is unlikely that NTFP use and trade will provide a pathway out of poverty for the millions of poor in the Global South. However, it is unlikely that any other one sector or intervention will. Consequently, the value of the NTFP sector and its role in poverty reduction for some needs to be added to the suite of strategies that governments, development agencies and NGOs consider when seeking to address poverty in the areas in which they operate.

- Description: A decolonial feminist community psychology approach understands individual experience as being embedded in, enabled and shaped by discursive and social power relations, and that transformative change is only possible through this contextualised understanding of individual experiences. African feminisms have been concerned with the challenging task of exploring and producing accounts of the complexity and multiplicity in womxn’s (and mxn’s) experiences of localised, multiple forms of oppression and the resistances enacted against them. We demonstrate how the utilisation of a narrative-discursive method in research that is guided by poststructural and postcolonial African feminist theorising may be a useful tool in realising the goals and aims of both decolonial feminist community psychology, and African feminist theorising. In this chapter, we draw on research that explored Zimbabwean womxn’s narratives of abortion decision-making and South African womxn’s and healthcare providers’ narratives of their experiences of the pre-abortion counselling healthcare encounter in the Eastern Cape public health sector. We also draw on our own intervention, a policy brief that had been developed into pre-abortion counselling guidelines which were informed by womxn’s narrated experiences. We argue that applying a narrative-discursive approach to African feminist theorising enables understandings of African womxn’s experiences and resistances which are informed by definitions of racial identity and culture, womxnhood, and social reality as dynamic social concepts and practices. These kinds of understandings facilitate community psychology interventions that are relevant and ‘emancipatory’ as they stem from the multiplicity of participants’ narrated experiences and the social and discursive power relations implicit in these narratives.

African feminisms have been concerned with the challenging task of exploring and producing accounts of the complexity and multiplicity in womxn’s (and mxn’s) experiences of localised, multiple forms of oppression and the resistances enacted against them. We demonstrate how the utilisation of a narrative-discursive method in research that is guided by poststructural and postcolonial African feminist theorising may be a useful tool in realising the goals and aims of both decolonial feminist community psychology, and African feminist theorising. In this chapter, we draw on research that explored Zimbabwean womxn’s narratives of abortion decision-making and South African womxn’s and healthcare providers’ narratives of their experiences of the pre-abortion counselling healthcare encounter in the Eastern Cape public health sector. We also draw on our own intervention, a policy brief that had been developed into pre-abortion counselling guidelines which were informed by womxn’s narrated experiences. We argue that applying a narrative-discursive approach to African feminist theorising enables understandings of African womxn’s experiences and resistances which are informed by definitions of racial identity and culture, womxnhood, and social reality as dynamic social concepts and practices. These kinds of understandings facilitate community psychology interventions that are relevant and ‘emancipatory’ as they stem from the multiplicity of participants’ narrated experiences and the social and discursive power relations implicit in these narratives.

- Description: The first of the 17 Global Goals that make up the 2030 Agenda for Sustainable Development is to end poverty in all its forms everywhere. Although the numbers of poor people in the world has declined over the last few decades, it is still alarmingly high, being approximately 770 million in 2013 (Fig. 1) (World Bank in Understanding Poverty 2017). Currently the majority of the world’s poor live in rural areas, and their livelihoods are dominated by land-based activities including gathering of Non-Timber Forest Products (NTFPs). There were rela tively few studies offering more socially orientated perspectives and insights on the links between NTFP use, dependency and poverty. The ordinary people using NTFPs, their reasons for doing so and their experiences are given in this book.
