Geophysical characterization and 2D gravimetric modeling: Application to tectonic control of the Vitória-Trindade Ridge (VTR–ES, Brazil)

There are numerous inquiries regarding the origin and development of the Vitória-Trindade Ridge (VTR) in eastern Brazil, a major tectonic feature composed of seamounts, guyots, banks, and islands, prompting extensive studies in the region. These investigations aim to create a more precise crustal model to aid in understanding various geological phenomena, such as the separation of South America from Africa, the interaction between continental and oceanic crusts, and the behavior of oceanic fracture zones. These zones may have served as conduits for magma feeding into the ridge and adjacent areas, or the seamounts could have formed due to a fixed mantle plume related to the West-East trend. This study focuses on exploring the tectonic structure of the region, particularly the subsurface of the VTR, utilizing geophysical data modeling techniques. This includes data from topography, gravimetric and magnetic anomalies, and analysis of reflection seismic lines. The research aims to accurately characterize the geological and geophysical context of the continental margin and some igneous features in the offshore region of the Espírito Santo and Bahia states. The anomalous hotspots correlate with pre-existing fracture zones resulting from the Mesozoic rifting of South American and African continents, which due to later tectonic episodes, have masked traces of deep-seated tectonic structures. The integration of geophysical methods, particularly gravimetry and magnetometry, when combined with reflection seismic data and 2D modeling techniques, offer insights into the geodynamic processes involved in the formation of the volcanic ridge. The results obtained showed the interference generated by magmatism in the oceanic crust and the transition zone. The seismic data allowed the visualization of the approximate geometries and interrelationships of some volcanic edifices that are compared with the Davis Bank, located in the central region of the VTR.

Change trend and attribution analysis of leaf area index in the East African Plateau from 1982 to 2020.

The ecosystems on the East African Plateau are crucial for maintaining the biodiversity, water resource balance, and ecological equilibrium of the African continent. However, the spatiotemporal variations of vegetation and the driving factors remain unclear. We analyzed leaf area index (LAI) change trends in the East African Plateau based on the GIMMS LAI4g dataset and further conducted attribution analysis combining temperature and precipitation data, as well as 10 Dynamic Global Vegetation Models (DGVMs) in TRNEDY v9. The results showed that LAI of the East African Plateau had a modest change trend from 1982 to 1999 (2.5×10-3 m2·m-2·a-1), but significantly increased from 2000 to 2020 (5.2×10-3 m2·m-2·a-1), which was 2.1 times faster than that during 1982-1999. Temperature and precipitation had weak correlations with LAI from 1982 to 1999, but showed significant correlations from 2000 to 2020. The DGVMs demonstrated consistent attribution results, with temperature and precipitation contributing significantly more to the LAI variations from 2000 to 2020 compared to the period from 1982 to 1999. The results highlighted the key role of climate change in driving vegetation greening on the East African Plateau during 2000-2020, which could provide important evidence for ecological conservation and sustainable development strategies in the region.

Assessing the Tropospheric Impacts on Positioning Accuracy Using IGS02 Real-Time Service Data Versus Long-Convergence Static PPP in Gwagwalada, Abuja, Nigeria

Abstract: The International Association of Geodesy (IAG) has established the International GNSS Service-Real Time Service (IGS-RTS) as a service provider, offering real-time access to precise products like orbits, clock corrections, and code biases regarding satellite navigation and positioning system. These products serve as an alternative to ultra-rapid products in real-time applications. The performance of these products is assessed through daily statistics from Analysis Centres, which compare them to IGS rapid products. However, the accuracy of GPS real-time corrections for satellites during eclipsing periods was slightly reduced, attributed to the impact of environmental factors on the services. The speed of GNSS signals can be impacted by various atmospheric factors, including troposphere, temperature, pressure, and humidity, resulting in positioning inaccuracies and even giving rooms for signal jamming and hijacking. However, the unique weather conditions prevalent in the African continent are often overlooked during the development of error mitigation parameters and algorithms, which can lead to reduced accuracy in GNSS positioning in a region like Nigeria. The purpose of this study is to estimate the tropospheric impact on positioning with IGS02 Real Time Service data compared to long convergence Static-PPP in Gwagwalada Area Council, Abuja, Nigeria. The study adopts the determination of the GNSS Static observations (minimum of two hours per session) on the chosen stations as standard, determination of the IGS-RTS data observations using RTKLIB software; observations were done with IGS-RTS data stream of IGS02 and statistical tests were performed. The GNSS Static coordinates and IGS-RTS coordinates were validated from error due to troposphere, temperature, pressure, etc., with the computation of their mean horizontal and vertical uncertainties which have a similar level of accuracy but slightly differ at centimeter levels. The result shows the Root Mean Square (RMS) Error discrepancy of IGS02 at the Wet and Dry season, as compared with the Static-PPP was within 0.065(m) and 0.046(m) respectively.

An exploration of unusual antimicrobial resistance phenotypes in Salmonella Typhi from Blantyre, Malawi reveals the ongoing role of IncHI1 plasmids

Typhoid fever is a significant public health problem endemic in Southeast Asia and Sub-Saharan Africa. Antimicrobial treatment of typhoid is however threatened by the increasing prevalence of antimicrobial resistant (AMR) S. Typhi, especially in the globally successful lineage (4.3.1) which has rapidly spread in East and Southern Africa. AMR elements can be found either on plasmids or in one of the three chromosomal integration sites, and there is variability of this across the lineage. Several previous studies with Malawian isolates indicated a clonal, locally spreading lineage with chromosomally integrated resistance genes. In a recent study however we noted three isolates with unusual predicted resistance profiles, and we here present the resolved genomes of these isolates using long- and short-read sequencing. Our work shows that these isolates are potentially imported cases, most closely related to the recently described sub-lineage 4.3.1.EA1, and encode IncHI1 plasmids with reduced resistance profiles compared to the major reference sequence of these plasmids spreading in East Africa. Similar reduced resistance plasmids were reported in a recent large-scale study in five isolates from Tanzania, highlighting the urgency for better coverage of the African continent in genome studies to better understand the dynamics of these potentially co-circulating plasmids.

Infernal Heavens: Narratives of Africa. From Joseph Conrad’s Heart of Darkness to Abdulrazak Gurnah’s Paradise

Situated at the intersection of literary studies and cultural studies, the present article looks at how fictional representations of Africa have evolved over the past century, from Conrad’s canonical Heart of Darkness, which has unjustly become the landmark of colonial biased narratives of Africa despite the author’s declared disengagement with his protagonists’ perspectives, to Abdulrazak Gurnah’s recent reverse rewriting of Marlow’s journey, this time from the heart of darkness outward. Dwelling on the spatial metaphors of Heaven and Hell, this study argues that the two works under scrutiny put forward two essentially dichotomic representations of the same place, the African continent, which are largely dependent on the cultural environment and on cultural constraints. Whereas Conrad’s infernal depiction of Africa relies mostly on Eurocentric stereotypes and on a personal experience whose horror mostly stemmed from a cultural shock produced by experiencing difference as evil, Gurnah’s more complex and authentic depiction is a result of telling the story from within, as an insider, and reflecting on difference as productive diversity. In this respect, this study brings into discussion Ranjan Ghosh’s recent dialogue with J. Hillis Miller on Literature and Globalization (2016) to argue that a transnational, transcultural and transdisciplinary approach to the narrative text would actually result in bridging the gap of classical binary difference and would emphasize the immanence of the literary text. Thus, Gurnah’s Paradise reconstructs pre-WWI Africa from within, as a sum of lost Paradises which are by no means of Western extraction, while Conrad’s canonical Inferno echoes the fears of an empire.

Mosquito repellent propensity of hexane extract of <i>Cymbopogon citratus</i> Stapf. (Poaceae), lemongrass, cream and emulgel formulations

Malaria is a global threat affecting majorly the African continent with Nigeria having the highest burden of deaths from the disease. Prophylactic measures in addition to curative treatments are strategies used for eradication of malaria. This study aims to develop topical mosquito repellent from lemongrass (Cymbopogon citratus). Lemongrass extract was obtained by Soxhlet extraction using n-hexane, it was formulated as lemongrass extract cream (LGCM) and emugel (LGEM) at 1 and 2% w/w concentrations. Organoleptic properties, spreadability, pH and skin irritation test were evaluated. Percentage mosquito repellency (R) and complete protection time (CPT) assay using the animal (rodent) model were determined and compared with N, N-diethyl-meta-toluamide (DEET). Results showed all the formulations were non-gritty, homogenous, relatively stable upon storage for 30 days at room temperature except forLGCM 1. They were non-irritant to the skin; pH was in range of 5.3 – 8. Spreadability was optimum with LGCM, LGEM 1 and 2% w/w. Mosquito repellency was concentration dependent and ˃ 80% in LGCM 2 and LGEM 2 but emulgels exhibited better repellency. CPT was 4, 5 and 8h for LGCM 2, LGEM 2 and DEET respectively. This study shows that LGEM 2% may be considered as an efficient topical mosquito-repelling formulation.

Decolonization and Democratization in African Countries: The Impact of Liberal Democracy on Political Stability

Since the 1990s, the African continent has experienced dramatic changes in the political sphere. Specifically, as mentioned by Samuel Huntington in The Third Wave: Democratization in the Late Twentieth Century, many Sub-Saharan African countries have undergone democratic transitions, marked by reforms from one-party systems or military rule to multiparty systems with regular elections, a process that prominently features characteristics of Western-style liberal democracy. Despite the fact that African countries employing Western-style democracy have made certain progress in political development and social governance, many African countries that have undergone this political transformation exhibit a lack of political stability. As such, this article studies the development of liberal democracy and political stability in Kenya against the backdrop of the third wave of democratization. Through analyzing the historical and socio-economic contexts of African countries, it argues that the winner-take-all logic of the western representative democracy contradicts with the cultural tradition in African countries, which emphasizes social consensus and consultation. Considering the historical problems left since the colonial era, it adds to the difficulty of applying the western democracy in contemporary African countries, and thus results in the incompatibility between the liberal democracy model and the reality of African social contexts. Consequently, it is argued that the democratization process in Africa requires further exploration and more appropriate combination of advanced political institutions and the local contexts.

A Commentary on the Jurisdictional Challenges in the Rand- Dollar Exchange Manipulation "Cartel": Competition Commission of South Africa v Bank of America Merrill Lynch International Designated Activity Company [2023] ZACT 26 (30 March 2023)

Cartels are the most egregious of competition law transgressions, because they entail a concerted effort on the part of cartel members to deliberately distort the market through price fixing, bid rigging, market allocation and constraining the supply of goods and services. Despite efforts by national competition authorities in various countries to combat cartelism, cartels have proved to have long tentacles, often extending beyond borders and morphing into "cross-border cartels". This contribution discusses one of the major challenges that cross-border cartels poses to competition authorities, that of prosecutorial and penal jurisdiction. The note focusses on the "banking cartel" that has been and still is the subject of contentious litigation. In March 2023 the Competition Tribunal (the Tribunal) handed down judgment in the matter of the Competition Commission of South Africa v Bank of America Merrill Lynch International Designated Activity Company [2023] ZACT 26 (30 March 2023). There were several questions in the matter, including the jurisdiction of the South African competition authorities to investigate and prosecute firms not incorporated or operating in South Africa (pure peregrini). The Competition Commission (the Commission) had initiated proceedings in the Tribunal against a host of banks for alleged cartel conduct, and some of the respondent banks raised objections and exceptions relating to the jurisdiction of the South African competition authorities. The note observes that while national competition authorities may have prosecutorial jurisdiction against cross-border cartels, there is still a challenge in enforcing an order where cartels are non-resident in the country. The contribution also notes potential challenges to cartel enforcement on the African continent in light of the establishment of the African Continental Free Trade Area (AfCFTA). Due to the removal of various trade barriers, there is likely to be a rise in cross-border competition issues, including cross-border mergers and cross-border cartels. The note therefore discusses a pertinent issue, that of jurisdiction, which may well be a challenge within the AfCFTA.

Exploring Community-Supported Agriculture through Maslow’s Hierarchy: A Systematic Review of Research Themes and Trends

Community-supported agriculture (CSA) has emerged as a pivotal model for sustainable and humanistic agricultural practices, emphasizing the symbiotic relationship between food production, consumption, and sustainable ecosystems. Despite the growing interest, a comprehensive analysis of research themes and trends within the CSA framework remains sparse. This paper undertakes a systematic review of CSA literature from 1999 to 2023, identifying evolving research hotspots, dominant themes, and prospective directions by keyword analysis to corroborate Maslow’s hierarchy of needs theory. The research analysis location is categorized into four temporal phases, revealing a geographical expansion from North America to encompass Asia, Africa, and other continents. This expansion corroborates Maslow’s theory, illustrating a global shift from fulfilling basic physiological needs towards recognizing sustainable practices, particularly in developing regions. The results of temporal trends (5 phases) and the hotspots of keyword analysis support each other by showing a societal shift from basic sustenance to a deeper understanding of nutrition and diet. Most of the recent research keywords are grouped into the “environment” and “health and education” categories, indicating an increasing emphasis on transforming the food system and nutrition education. This review suggests conducting an integrated analysis that links the various stages of the food supply chain with the criteria outlined in the Sustainable Agriculture Matrix (SAM). It highlights that the “environment” theme is a stage of building up esteem and self-realization that needs to be unfolded in the future, given that most research on community-supported agriculture (CSA) focuses on the “economy and society” aspect and consumption stage, which burnish self-morality in the theory of Maslow. Overall, this review proposes an analysis of the relevance among different subject categories and between food supply chain stages, which reveals that the trend of research under CSA development is accorded to the theory of Maslow’s hierarchy of needs and calls for a more holistic approach to agricultural research that considers ecological, health, and social imperatives.

Exploring Multimorbidity Through the Use of Deterministic and Probabilistic Record Linkage of Data in Five Health Facilities in Nairobi

IntroductionData collected by Health Demographic Surveillance Systems (HDSSs) at the community level can support very powerful research questions if it was linked to records at health facilities. In particular, understanding multimorbidity and building predictive models for key health outcomes requires linked data collected both in the community and health facilities. Additionally, the linked data can assist health management teams at the national, county, and local levels in making evidence-based choices. Problemthe inability to link population level data with records at health facilities affects the ability to use data to solve key health research questions. lack of common identifiers affects the possibility of integrating clinic records with population-based data. MethodologyWe intend to link data from five health facilities in Nairobi County serving the population in the Nairobi Urban Health Demographic Surveillance System (NUHDSS) where longitudinal data was collected between 2001 and 2018. The longitudinal data is from a database of about 260,000 individuals. This will result in a merged dataset and will also provide an opportunity to assess the accuracy of the deterministic and probabilistic record linkage algorithm compared with other methods. Note: We will have results by the time the conference is happening as groundwork has been put. ConclusionThe growing burden of multimorbidity on the African continent requires creative and effective strategies of addressing the problem through utilization of existing longitudinal data. By merging clinic records with population-based data, this initiative will promote the use of data evidence informed decision making for interventions to address multimorbidity.

Modeling the Impacts of Diagnosis and Treatment of Snakebite Envenoming Victims with Anti-Snake Venom in a Community

Snakebite envenoming (SBE) is one of the major causes of deaths and disabilities in tropical and subtropical countries especially in the continents of Asia and Africa. Report revealed that on average, 5-8 and about 3,000 cases of SBE are recorded daily and yearly respectively in northeast Nigeria which population are largely agriculturists. Thus, snakebite (SB) led to economy setback and slows down productivity among the workforce as a result of disabilities induced by SBE. Consequently, the revenue generation even including income facing declined. This paper proposes population-based mathematical model for studying the dynamic impacts of diagnosis and treatment of snakebite envenoming victims with anti-snake venom in a community. The model is rigorously analyzed using relevant techniques and theorems in dynamical systems. The model was validated using monthly reported data on snakebite envenoming from 2020–2022, collected from snakebite treatment and research hospital (STRH) Kaltungo in northeast Nigeria. The qualitative study revealed that the model has snakebite-envenoming-free and snakebite-envenoming-endemic equilibrium points. It is shown via the Lyapunov function in conjunction with the Lassale invariance principle that these two equilibrium points are globally asymptotically stable. Furthermore, numerical simulations of the model were carried out to investigate the impact of the diagnosis of snakebite envenoming victims and the treatment of the same on the burden of snakebite envenoming. The results of the simulations revealed that appropriate diagnosis and treatment of snakebite envenoming victims with anti-snake venom could significantly reduce the number of snakebite-induced deaths and disabilities. This work can serve as a framework for making policy and decision in addressing the issues of SBE in the public healthcares in the study region and beyond.

Commitment to corporate social entrepreneurship in the context of a health crisis: The case of the scientist–entrepreneur couple who founded BioNTech

ABSTRACT If corporate social responsibility (CSR) calls for a virtuous process in which health for all becomes egalitarian, ethical and equitable, the health crisis (COVID-19) revealed certain limitations to this process. The aim of our research is to identify the limitations that can hinder corporate social entrepreneurship (CSE)’s commitment of coentrepreneurs (founders of BioNTech) in the dissemination of “their” vaccine in the context of a health crisis. The difficulties encountered in disseminating the Comirnaty vaccine (Pfizer–BioNTech) on the African continent are exemplary in this respect. A literature review presents the concept of CSE associated with the contributive advantage concept in the creation of social and economic values. We then present two research proposals: How can CSE influence the double CSR performance (social and economic) of copreneurs? What kinds of limitations may hinder CSE’s commitment to success in a health crisis context? Are ethics and profit always reconcilable? Concerning the research method, we use a qualitative approach with the investigation of a unique case study of the scientist–entrepreneur couple who founded BioNTech and led the Lightspeed project that gave birth to the Comirnaty vaccine Concerning the results by showing how CSE could expand the scope of companies’ activities and their organizational values, we are pushing them to rethink their current CSR approaches by combining team commitment, will, and desire to create common economic and social values. We also have illustrated a promising path for practitioners in a crisis context, where they can achieve their economic and social objectives to take a sustainable advantage.

Navigating Climate Change and Sustainability Solutions: Nigeria's Role in International Environmental Law

Over the past three decades, the world has witnessed multidimensional impacts of climate change, thus emphasizing the critical urgency for climate action, and promoting sustainability. Africa is reported to disproportionately suffer the consequences of climate change. These consequences such as flooding; droughts and rising temperatures require the adoption of an environmental foreign policy to foster environmental sustainability and cross-sectoral climate resilience. As Africa’s most populous nation and second-largest oil producer significant to global oil supply, Nigeria occupies a unique and distinct position in the global climate discourse. However, despite credibly being a signatory to international bodies such as the United Nations Framework Convention on Climate Change (UNFCCC), Nigeria needs an effective environmental foreign policy to attain the globally desired sustainability and climate resilience. Therefore, this paper delves into Nigeria’s commitment to international environmental law of key international agreements, such as the Paris Agreement, in response to the threatening climate change crisis. The paper recognizes Nigeria as a leading contributor to greenhouse gas emissions in Africa, driving it to develop some national environmental policies that support renewable energy production and sustainability. However, most of the policies seem ineffective. This is because the country needs help with challenges ranging from political interference, corruption, unrealistic emission targets, overreliance on fossil fuels, and other socioeconomic factors. The study highlights the potential of Nigeria, the giant of Africa, in leading regional climate negotiations by localizing international environmental foreign policy and developing a strengthened legal framework to guide the African continent to sustainable development. The perspective of this paper is to encourage Nigeria to meet its sustainability objectives while fulfilling its international environmental obligations by exploring its abundant renewable energy resources such as solar, wind, and hydropower

Sino-Africa Relations Post-Covid-19: Issues for Consideration

Sino-Africa relations have been periodised into three phases. The first phase (1950s–1970s) includes the establishment of the People’s Republic of China (PRC) in 1949 and the decolonisation of African states. The second phase (1971–1990s) includes the drift of Sino-Soviet relations, the admission of China into the United Nations Security Council (UNSC), as well as the end of the Cold War. The third phase (2000s–2020) covers the inclusion of China into the World Trade Organisation (WTO) in 2001, as well as the establishment of the Forum on China-Africa Cooperation (FOCAC) in 2010. This article considers the fourth phase of Sino-Africa relations, argued to have begun in 2020 post-Covid-19, taking place at a time of de-globalisation, the ongoing Russia-Ukraine war and the US-China trade war. We assert that the latter changing global dynamics must be considered in making sense of Sino-Africa relations today. The article argues that despite such a changing global political order, there have been continuities and changes in China’s relations with the African continent. This is evident in the tightening of its relations with Africa, irrespective of ongoing dynamics in global affairs. Despite concerns about the USA’s reprioritisation of Africa, the establishment of the African Continental Free Trade Area (AfCFTA), China’s Belt and Road Initiative (BRI), vaccine diplomacy, and China and African States’ “neutrality” stance on various ongoing conflicts, it is safe to say that Sino-Africa relations will triumph even in this new phase.

Africanizing the SDGs: A key factor for enhancing sustainability consciousness within South African universities

The Sustainable Development Goals (SDGs) can be viewed as the aftermath of the Millennial Development Goals (MDGs). This is due to the fact that the seventeen (17) SDGs are designed to continue the work expected to have been done by the MDGs. In other words, the failure of the MDGs to eradicate poverty birthed the SDGs. However, the SDGs seem not to be achieving the desired result. This has led to the projection for the need for a decade of action. In the African context, the questions of why the MDGs failed and the SDGs tend to be failing are yet to be asked. By projection, if the questions are not asked and answers are not provided, the projection of the decade of action may also fail. Hence, the reason for this conceptual paper which was targeted at exploring the possibility of considering the Africanization of the SDGs as remedy to ensuring sustainable development in the African continent. Different relevant sources were identified, reviewed and analysed. The findings from the reviewed and analysed sources showed among others that for Africanization of the SDGs to be a reality and practicable, glocalization must be embraced. Meanwhile, there will be need to question the use of Eurocentric curricula in African institutions of learning.

Fermented fruits and legumes in Africa: production factors and health benefits

SummaryFermentation is an age‐long food processing tool used to preserve and develop functional foods and beverages. Fruits in particular have a very short shelf life due to their high water activity, favourable to microbial decomposition and spoilage, while legumes are protein‐rich crops that require improved protein digestibility. These are some standout reasons for applying this tool to develop fermented fruit‐ and legume‐based products. From multifarious fruit‐based beers, non‐alcoholic beverages and alcoholic drinks to legume‐based condiments and meals, fermentation has been used over time in Africa to enhance the food security, safety, nutrition, healthfulness and livelihoods of the people. As the nutrition and economic prospects of African fermented fruit‐ and legume‐based products are huge not only to the African continent but globally (as African diasporans and their interracial friends, spouses and relatives are notably consuming them), they are fraught with opportunities and challenges. This review describes the production factors (including raw material selection, processing techniques, environmental conditions and the role of microorganisms) and health benefits of these African fermented products. Safety concerns, fermentation challenges and other considerations are also discussed. Further studies targeting fermentation and production of novel, healthy and safer fruit‐ and legume‐based African food products are warranted due to their potential positive contribution to African and global hunger and malnutrition issues.

Strawberries in a warming world: examining the ecological niche of Fragaria×ananassa Duch – Across different climate scenarios

BACKGROUND: Strawberry (Fragaria×ananassa Duch.) is a species of great economic and nutritional importance. It is widely cultivated in different regions of the world. However, climatic factors have a significant influence on its production. OBJECTIVE: To evaluate the ecoclimatic suitability and growth index of F.×ananassa in the face of the impacts of climate change in Brazil and the world. METHODS: The potential global distribution of F.×ananassa it was based on predicted global climate changes using CLIMEX and the A1B and A2 emissions scenario for the years 2050 and 2100. CLIMEX weekly growth index (GIw) was applied, and productivity data in commercial strawberry cultivation in Brazilian areas were collected. RESULTS: The results indicate a progressive reduction in areas suitable for strawberry cultivation globally, mainly on the African continent, Australia, China, and the Americas for the years 2050 and 2100. In Brazil, only the South region and part of the Southeast will continue to be suitable for strawberry production. CONCLUSIONS: The CLIMEX model predicts a reduction in the suitable area for cultivating Fragaria×ananassa Duch between 2050 and 2100 due to climate change. The generated maps can help identify new cultivation areas and support genetic improvement programmes to develop cultivars more tolerant to heat.

Trust as moral currency: Perspectives of health researchers in sub-Saharan Africa on strategies to promote equitable data sharing.

Groundbreaking data-sharing techniques and quick access to stored research data from the African continent are highly beneficial to create diverse unbiased datasets to inform digital health technologies and artificial intelligence in healthcare. Yet health researchers in sub-Saharan Africa (SSA) experience individual and collective challenges that render them cautious and even hesitant to share data despite acknowledging the public health benefits of sharing. This qualitative study reports on the perspectives of health researchers regarding strategies to mitigate these challenges. In-depth interviews were conducted via Microsoft Teams with 16 researchers from 16 different countries across SSA between July 2022 and April 2023. Purposive and snowball sampling techniques were used to invite participants via email. Recorded interviews were transcribed, cleaned, coded and managed through Atlas.ti.22. Thematic Analysis was used to analyse the data. Three recurrent themes and several subthemes emerged around strategies to improve governance of data sharing. The main themes identified were (1) Strategies for change at a policy level: guideline development, (2) Strengthening data governance to improve data quality and (3) Reciprocity: towards equitable data sharing. Building trust is central to the promotion of data sharing amongst researchers on the African continent and with global partners. This can be achieved by enhancing research integrity and strengthening micro and macro level governance. Substantial resources are required from funders and governments to enhance data governance practices, to improve data literacy and to enhance data quality. High quality data from Africa will afford diversity to global data sets, reducing bias in algorithms built for artificial intelligence technologies in healthcare. Engagement with multiple stakeholders including researchers and research communities is necessary to establish an equitable data sharing approach based on reciprocity and mutual benefit.
