RESUMO

Global assessments of mycorrhizal symbiosis present large sampling gaps in rich biodiversity regions. Filling these gaps is necessary to build large-scale, unbiased mycorrhizal databases to obtain reliable analyses and prevent misleading generalizations. Underrepresented regions in mycorrhizal research are mainly in Africa, Asia, and South America. Despite the high biodiversity and endemism in these regions, many groups of organisms remain understudied, especially mycorrhizal fungi. In this Viewpoint, we emphasize the importance of inclusive and collaborative continental efforts in integrating perspectives for comprehensive trait database development and propose a conceptual framework that can help build large mycorrhizal databases in underrepresented regions. Based on the four Vs of big data (volume, variety, veracity, and velocity), we identify the main challenges of constructing a large mycorrhizal dataset and propose solutions for each challenge. We share our collaborative methodology, which involves employing open calls and working groups to engage all mycorrhizal researchers in the region to build a South American Mycorrhizal Database. By fostering interdisciplinary collaborations and embracing a continental-scale approach, we can create robust mycorrhizal trait databases that provide valuable insights into the evolution, ecology, and functioning of mycorrhizal associations, reducing the geographical biases that are so common in large-scale ecological studies.

RESUMO

Globally, fertility awareness efforts include well-established risk factors for fertility problems. Risks disproportionately affecting women in the Global South, however, are neglected. To address this gap, we conducted a systematic review and meta-analyses of relevant risk factors to examine the association between risk factors and fertility problems. MEDLINE, Embase, Cochrane Library, regional databases and key organizational websites were used. Three authors screened and extracted data independently. Studies assessing exposure to risk (clinical, community-based samples) were included, and studies without control groups were excluded. Outcome of interest was fertility problems, e.g. inability to achieve pregnancy, live birth, neonatal death depending on study. The Newcastle-Ottawa Scale was used to assess study quality. A total of 3843 studies were identified, and 62 were included (58 in meta-analyses; n = 111,977). Results revealed the following: a ninefold risk of inability to become pregnant in genital tuberculosis (OR 8.91, 95% CI 1.89 to 42.12); an almost threefold risk in human immunodeficiency virus (OR 2.93, 95% CI 1.95 to 4.42) and bacterial vaginosis (OR 2.81, 95% CI 1.85 to 4.27); a twofold risk of tubal-factor infertility in female genital mutilation/cutting-Type II/III (OR 2.06, 95% CI 1.03 to 4.15); and postnatal mortality in consanguinity (stillbirth, OR 1.28, 95% CI 1.04 to 1.57; neonatal death, OR 1.57, 95% CI 1.22 to 2.02). It seems that risk factors affected reproductive processes through multiple pathways. Health promotion encompassing relevant health indicators could enhance prevention and early detection of fertility problems in the Global South and disproportionately affected populations. The multifactorial risk profile reinforces the need to place fertility within global health initiatives.

RESUMO

Conservationists increasingly position conservation that is mutually beneficial to people and biodiversity on the promise of empowerment of people through participatory discourse, metrics, processes, and outcomes. Empowerment represents multidimensional concepts and theories that permeate the interlinking levels of power, from the psychological to the political, and social scales in which conservation operates. The multifaceted nature of empowerment makes it challenging to understand, pursue, and evaluate as a central philosophical commitment and goal-oriented practice in conservation. Moreover, definitional and methodological uncertainty may disempower interested and affected groups because they can foster conceptual assumptions that reinforce institutionalized barriers to systemic changes. Despite these complexities, there are no targeted reviews of empowerment in conservation. We conducted a scoping review of the conservation literature to synthesize the meanings and uses of empowerment in the field. We reviewed 121 of the most cited conservation articles that invoked or assessed empowerment from 1992 to 2017 to document geographic, conceptual, and methodological trends in the scales and theories of empowerment deployed by conservationists. Research claiming or assessing empowerment through conservation often focused on communities in the Global South. Most studies relied on qualitative and mixed methods (78%) collected largely from male or non-Indigenous participants. Few studies (30%) defined the 20 types of empowerment they referenced. Fewer studies (3%) applied empowerment theories in their work. Our findings show that empowerment discourse of local and Indigenous communities permeates the discourse of people-centered conservation. Yet, overreliance on empowerment's rhetorical promise and minimal engagement with theory (e.g., postcolonial theory) risks disempowering people by obscuring empowerment's foundational value to conservation and communities and oversimplifying the complex realities of people-centered conservation. Lasting change could come from more meaningful engagement with empowerment, including coproducing definitions and measures with and for disempowered social groups to tackle widespread power disparities in conservation today.


El alcance del empoderamiento para la conservación y las comunidades Resumen Con frecuencia los conservacionistas posicionan a la conservación como benéfica para las personas y la biodiversidad mediante discursos, medidas, procesos y resultados participativos que prometen el empoderamiento de la gente. El empoderamiento representa conceptos y teorías multidimensionales que permean los niveles interconectados de poder, desde el psicológico al político, y las escalas sociales en las que opera la conservación. La naturaleza multifacética del empoderamiento complica que se entienda, se dé seguimiento y se evalúe como un compromiso filosófico central y una práctica orientada hacia las metas dentro de la conservación. Además, la incertidumbre metodológica y de definición pueden restar autoridad a los grupos interesados o afectados pues pueden promover suposiciones conceptuales que refuerzan las barreras institucionales de los cambios sistémicos. A pesar de estas complejidades, no existen revisiones focalizadas del empoderamiento en la conservación. Realizamos una revisión de alcance de la literatura de conservación para sintetizar los significados y usos de la palabra empoderamiento en este campo. Revisamos 121 de los artículos sobre conservación más citados que invocaron o evaluaron el empoderamiento entre 1992 y 2017 para documentar las tendencias geográficas, conceptuales y metodológicas en las escalas y teorías del empoderamiento usadas por los conservacionistas. La mayoría de los artículos que afirmaban o evaluaban el empoderamiento por medio de la conservación se enfocaron en comunidades del Sur Global. La mayoría de los estudios dependieron de métodos cualitativos y mixtos (78%) tomados principalmente de participantes masculinos o no indígenas. Pocos estudios (30%) definieron los 20 tipos de empoderamiento que referenciaron. Todavía menos estudios (3%) aplicaron las teorías de empoderamiento a su trabajo. Nuestros descubrimientos muestran que el discurso de empoderamiento de las comunidades locales e indígenas permea el discurso de la conservación centrada en la gente. Sin embargo, depender en exceso de la promesa retórica del empoderamiento e involucrarse en lo mínimo con la teoría (p. ej.: teoría postcolonial) arriesga que la gente se pierda autoridad al oscurecer el valor fundamental que tiene el empoderamiento para la conservación y las comunidades y simplificar sobremanera las realidades complejas de la conservación centrada en las personas. El cambio duradero podría venir de involucrarse de forma más significativa con el empoderamiento, lo que incluye la coproducción de definiciones y medidas con y para los grupos sociales no empoderados para resolver la disparidad de poder que existe hoy en día en la conservación.

RESUMO

Biodiversity research is essential for addressing the global biodiversity crisis, necessitating diverse participation and perspectives of researchers from a wide range of backgrounds. However, conservation faces a significant inclusivity problem because local expertise from biodiversity-rich but economically disadvantaged regions is often underrepresented. This underrepresentation is driven by linguistic bias, undervalued contributions, parachute science practices, and capacity constraints. Although fragmented solutions exist, a unified multistakeholder approach is needed to address the interconnected and systemic conservation issues. We devised a holistic framework of collective responsibility across all research participants and tailored strategies that embrace diversity and dismantle systemic barriers to equitable collaboration. This framework delineates the diverse actors and practices required for promoting inclusivity in biodiversity research, assigning clear responsibilities to researchers, publishers, institutions, and funding bodies. Strategies for researchers include cultivating self-awareness, expanding literature searches, fostering partnerships with local experts, and promoting knowledge exchange. For institutions, we recommend establishing specialized liaison roles, implementing equitable policies, allocating resources for diversity initiatives, and enhancing support for international researchers. Publishers can facilitate multilingual dissemination, remove financial barriers, establish inclusivity standards, and ensure equitable representation in peer review. Funders must remove systemic barriers, strengthen research networks, and prioritize equitable resource allocation. Implementing these stakeholder-specific strategies can help dismantle deep-rooted biases and structural inequities in biodiversity research, catalyzing a shift toward a more inclusive and representative model that amplifies diverse perspectives and maximizes collective knowledge for effective global conservation.


Estrategias para las prácticas equitativas y la responsabilidad colectiva en la investigación de la biodiversidad Resumen La investigación sobre biodiversidad es esencial para hacer frente a la crisis mundial de la biodiversidad, por lo que requiere la participación y la variedad de perspectivas de investigadores de diferente procedencia. Sin embargo, la conservación se enfrenta a un importante problema de inclusión, ya que los expertos locales de regiones ricas en biodiversidad, pero con economías desfavorecidas suelen estar infrarrepresentados. Esta infrarrepresentación se debe a prejuicios lingüísticos, contribuciones infravaloradas, prácticas científicas paracaidistas y limitaciones de capacidad. Aunque existen soluciones fragmentadas, se necesita un enfoque unificado de los múltiples actores para abordar los problemas de conservación interconectados y sistémicos. Ideamos un marco holístico de responsabilidad colectiva de todos los participantes en la investigación y estrategias a medida que abarcan la diversidad y desmantelan las barreras sistémicas a la colaboración equitativa. Se necesitan diversos actores y estrategias para promover la inclusión en la investigación sobre biodiversidad, y deben asignarse claramente las responsabilidades de investigadores, editores, instituciones y organismos de financiación. Las estrategias para los investigadores incluyen fomentar la autoconciencia, ampliar las búsquedas bibliográficas, fomentar las asociaciones con expertos locales y promover el intercambio de conocimientos. Para las instituciones, recomendamos establecer funciones de enlace especializadas, aplicar políticas equitativas, asignar recursos a iniciativas de diversidad y mejorar el apoyo a los investigadores internacionales. Las editoriales pueden facilitar la difusión multilingüe, eliminar barreras financieras, establecer normas de inclusión y garantizar una representación equitativa en la revisión por pares. Los financiadores deben eliminar las barreras sistémicas, reforzar las redes de investigación y dar prioridad a la asignación equitativa de recursos. La aplicación de estas estrategias específicas puede ayudar a desmantelar prejuicios profundamente arraigados y desigualdades estructurales en la investigación de la biodiversidad, catalizando un cambio hacia un modelo más inclusivo y representativo que amplifique las diversas perspectivas y maximice el conocimiento colectivo para una conservación global eficaz.

RESUMO

Diarrhea is a leading cause of death in children globally, mostly due to inadequate sanitary conditions and overcrowding. Poor housing quality and lack of tenure security that characterize informal settlements are key underlying contributors to these risk factors for childhood diarrhea deaths. The objective of this study is to better understand the physical attributes of informal settlement households in Latin American cities that are associated with childhood diarrhea. We used data from a household survey (Encuesta CAF) conducted by the Corporación Andina de Fomento (CAF), using responses from sampled individuals in eleven cities. We created a household deprivation score based on household water and sewage infrastructure, overcrowding, flooring and wall material, and security of tenure. We fitted a multivariable logistic regression model to estimate odds ratios (OR) and 95% confidence intervals (95% CI) to test the association between the deprivation score and its individual components and childhood diarrhea during the prior 2 weeks. We included a total of 4732 households with children, out of which 12.2% had diarrhea in the 2-week period prior to completing the survey. After adjusting for respondent age, gender, and city, we found a higher risk of diarrhea associated with higher household deprivation scores. Specifically, we found that the odds of diarrhea for children living in a mild and severe deprived household were 1.04 (95% CI 0.84-1.28) and 3.19 times (95% CI 1.80-5.63) higher, respectively, in comparison to households with no deprivation. These results highlight the connections between childhood health and deprived living conditions common in informal settlements.

RESUMO

In many contexts, responsibility for exit-level assessment design and implementation in undergraduate medical programmes lies with individuals who convene clinical clerkships. Their assessment practice has significant consequences for students' learning and the patients and communities that graduates will serve. Interventions to enhance assessment must involve these assessors, yet little is known about factors influencing their assessment practice. The purpose of this study was to explore factors that influence assessment practice of clerkship convenors in three varied low-and-middle income contexts in the global South. Taking assessment practice as a behaviour, Health Behaviour Theory (HBT) was deployed as a theoretical framework to explore, describe and explain assessor behaviour. Thirty-one clinician-educators responsible for designing and implementing high-stakes clerkship assessment were interviewed in South Africa and Mexico. Interacting personal and contextual factors influencing clinician-educator assessment intention and action were identified. These included attitude, influenced by impact and response appraisal, and perceived self-efficacy; along with interpersonal, physical and organisational, and distal contextual factors. Personal competencies and conducive environments supported intention to action transition. While previous research has typically explored factors in isolation, the HBT framing enabled a systematic and coherent account of assessor behaviour. These findings add a particular contextual perspective to understanding assessment practice, yet also resonate with and extend existing work that predominantly emanates from high-income contexts in the global North. These findings provide a foundation for the planning of assessment change initiatives, such as targeted, multi-factorial faculty development.

RESUMO

The developmental science literature predominantly originates from WEIRD (Western, Educated, Industrialized, Rich, and Democratic) countries. This bias perpetuates colonial power imbalances and marginalizes non-WEIRD societies' knowledge. This special issue addresses this gap by focusing on Latin America, emphasizing the region's diverse socioeconomic, cultural, and political contexts. This commentary contextualizes research in Latin America, and then presents and discusses the articles. Finally, it presents some of the challenges researchers in Latin America face.

RESUMO

Mounting evidence that growth mindset-the belief that intelligence is not fixed and can be developed-improves educational outcomes has spurred additional interest in how to measure and promote it in other contexts. Most of this research, however, focuses on high-income countries, where the most common protocols for measuring and intervening on student mindsets rely on connected devices-often unavailable in low- and middle-income countries' schools. This paper develops a toolkit to measure student mindsets in resource-constrained settings, specifically in the context of Brazilian secondary public schools. Concretely, we convert the computer-based survey instruments into text messages (SMS). Collecting mindset survey data from 3570 students in São Paulo State as schools gradually reopened in early 2021, we validate our methodology by matching key patterns in our data to previous findings in the literature. We also train a machine learning model on our data and show that it can (1) accurately classify students' SMS responses, (2) accurately classify student mindsets even based on text written in other media, and (3) rate the fidelity of different interventions to the published growth mindset curricula.

RESUMO

Contextualizing the void of research on inhalant abuse among adolescents as epistemic neglect, in this study, we use mixed-methods action research to understand inhalant abuse in a specific context in the Global South. Focusing on a large metropolitan city in Western India, we surveyed 158 street-involved children and adolescents (110 boys and 48 girls, age range from 5 to 17 years) in a group setting along with follow-up group interviews. Despite finding a high prevalence rate of inhalant abuse, our work suggests an absence of supporting structures and emphasizes the need to revisit our understanding and interpretation of substance-using behavior of street-involved youth. Instead of explaining inhalant-abusing behavior as emerging from pathological deficiencies in individuals or households, we stress the need to critically examine the exploitative environment they are embedded in. In doing so, we join efforts to decolonize conventional ways of understanding "deviant" behavior.

RESUMO

Issue: There is an unspoken requirement that medical education researchers living in the Global South must disseminate their work using dominant frames constructed by individuals living in the Global North. As such, the published literature in our field is dominated by researchers whose work primarily benefits the Western world, casting the rest of what is published as localized and unhelpful knowledge. In this article, we use Audre Lorde's conception of the Master's house as a metaphor to narrate the experiences of two South African medical education researchers trying to disseminate their work into North American venues. In addition to narrating these stories, we describe the personal and professional consequences they experienced as a result of their efforts. Evidence: For researchers working outside of the Global North, entering the Master's formidable house is daunting, and there is no clear pathway in. These narratives illustrate how reviewers and editorial staff act as gatekeepers, continuously shaping ideas about what it means to do acceptable research, and who is allowed to disseminate it within the field. These narratives also show that those who have been rejected by these gatekeepers are often conflicted about their position within the larger field of medical education. Implications: To begin to address this issue, we have made several suggestions for the research community to consider. First, medical education research journals need to create spaces for researchers publishing from the Global South. One suggestion is for journals to create a submission type that is dedicated to researchers working outside of North America. Second, journals should also include more Global South editors and reviewers to help with knowledge translation when articles are submitted from outside North America. If our collective goal is to improve the training of physicians and the health outcomes of humanity, then we need to renovate the Master's house and begin to break down the barriers that separate us from truly building together.

RESUMO

Despite recent calls to engage in scholarship with attention to anti-racism, equity, and social justice at a global level in Health Professions Education (HPE), the field has made few significant advances in incorporating the views of the so-called "Other" in understanding the nature, origin, and scope of knowledge as well as the epistemic justification of knowledge production. Editors, authors, and reviewers must take responsibility for questioning existing systems and structures, specifically about how they diffuse the knowledge of a few and silence the knowledge of many. This article presents 12 recommendations proposed by The Global South Counterspace Authors Collective (GSCAC), a group of HPE professionals, representing countries in the Global South, to help the Global North enact practical changes to become more inclusive and engage in authentic and representative work in HPE publishing. This list is not all-encompassing but a first step to begin rectifying non-inclusive structures in our field.

RESUMO

In the Global South, young people who use drugs (YPWUD) are exposed to multiple interconnected social and health harms, with many low- and middle-income countries enforcing racist, prohibitionist-based drug policies that generate physical and structural violence. While harm reduction coverage for YPWUD is suboptimal globally, in low- and middle-income countries youth-focused harm reduction programs are particularly lacking. Those that do exist are often powerfully shaped by global health funding regimes that restrict progressive approaches and reach. In this commentary we highlight the efforts of young people, activists, allies, and organisations across some Global South settings to enact programs such as those focused on peer-to-peer information sharing and advocacy, overdose monitoring and response, and drug checking. We draw on our experiential knowledge and expertise to identify and discuss key challenges, opportunities, and recommendations for youth harm reduction movements, programs and practices in low- to middle-income countries and beyond, focusing on the need for youth-driven interventions. We conclude this commentary with several calls to action to advance harm reduction for YPWUD within and across Global South settings.

RESUMO

PURPOSE: The availability of children's surgical care in lower middle-income countries is lacking. The authors describe a hub and spoke global training initiative in children's surgery for adult teams from district hospitals (spokes) comprising general and orthopaedic surgeons, anaesthetists, and nurses and specialist children's surgical trainers from tertiary centres (hubs) in delivering the course. METHODS: The training course developed in Vellore, trained several sets of district hospital adult teams and trainer teams in India. Six specialist children's surgical trainer teams were invited from African countries to the course delivered in Vellore, India. The aim was to train them to deliver the course in their countries. RESULTS: Participants underwent a precourse 'train the trainer' program, observed and assessed the suitability of the district hospital training course. The program received positive feedback, government supported planning of similar courses in some of the countries and discussions in others. CONCLUSION: The availability of children's surgical care is similarly limited in the Asian and African continent, and the regions have shared challenges of disease burden, lack of access, poverty, deficient infrastructure, and trained human resources. They would benefit from this 'South to South' collaboration to impart training skills and modules to the children's surgical trainers.

RESUMO

Mineral extraction plays a pivotal role in economic growth and development of the Global South, serving as a cornerstone for numerous industries and contributing significantly to national economies. However, its exploitation often comes with significant environmental and social challenges. This research paper examines the impacts of mineral extraction on environmental sustainability and social equity in the Global South, focusing particularly on China over the past two decades (2002-2022). Utilizing the Dynamic Autoregressive Distributed Lag (DARDL) methodology, we offer a comprehensive empirical analysis of the impact of mineral extraction on environmental and social implications. Our findings provide an in-depth perspective, highlighting the multifaceted nature of this relationship. The study underscores the temporal dynamics and evolving nature of the environmental and social repercussions associated with mineral extraction. It offers critical insights for policymakers, industry stakeholders, and civil society organizations engaged in the Global South.

RESUMO

The integrity of natural ecosystems, particularly in the Global South, is increasingly compromised by industrial contaminants. Our study examines the growth of plant species adapted to ecosystems impacted by heavy metal pollution, specifically focusing on their phytoremediation capabilities and tolerance to contaminants. The potential of pollution-tolerant species was evaluated in the industrial subtropical wetland of Sialkot, Pakistan. Employing quantitative ecological methods, data on vegetation, phytosociological attributes, and soil properties were gathered from 450 plots across different pollution gradients. The study pinpointed 17 key indicator species tolerating high heavy metal pollution out of 182 surveyed, using a combination of Indicator Species Analysis (ISA) and the Importance Value Index (IVI). These species demonstrated diverse capacities to extract, stabilize, and accumulate heavy metals (Cr, Zn, Cu, As, Cd, Ni, Hg, and Pb) across varying pollution zones. Notably, Cannabis sativa demonstrated substantial phytoextraction of Zn and Cd, with concentrations reaching 1977.25 µg/g and 1362.78 µg/g, respectively. Arundo donax showed marked hyperaccumulation of Cd, peaking at 410.531 µg/g. Achyranthes aspera was remarkable for its extraction and accumulation of Ni and Cu, with concentrations of 242.412 µg/g and 77.2997 µg/g, respectively. Physiological changes, such as increased proline levels in Cannabis sativa and Achyranthes aspera reaching 39.041 µg/g and 27.523 µg/g under high metal concentrations, indicated adaptation to metal stress. Declines in chlorophyll and carotenoid levels were also observed as metal contamination increased, with up to 35% reductions in some species. These findings underscore the potential efficacy of selected plant species in phytoremediation and highlight the importance of physiological responses in their tolerance to metals, providing valuable information for targeted remediation strategies in polluted ecosystems and improving environmental management and sustainable practices.

RESUMO

A significant body of research has documented the profound changes in global atmospheric conditions during the COVID-19 pandemic. However, there is still an inadequate comprehensive comparison and assessment of countries before, during, and after the pandemic. Variations in restriction policies, human behaviors, and national traits lead to significant differences in how restriction policies affect atmospheric pollution. This study focuses on NO2, a pollutant with high temporal sensitivity, and utilizes the Oxford COVID-19 policy stringency index along with demographic information. Through spatial-temporal mapping, we analyzed NO2 emission fluctuations and calculated the emission changes in each country. Drawing from this analysis, we explored the relationships among these factors and found that over the span of 2019-2022, across 193 countries, global NO2 emissions displayed a distinct trajectory: initially decreasing, subsequently rebounding, and eventually fluctuating. Most countries exhibited seasonal variations in NO2 emissions. Additionally, the study uncovered a correlation between the stringency of COVID-19 policies and the reduction in NO2 emissions: as policies became stricter, emissions significantly decreased in most countries. In contrast, in countries with lower population densities, stricter policies paradoxically led to an increase in emissions. These findings underscore the importance of considering demographic factors and geographical context in the formulation and implementation of environmental policies.

RESUMO

In Global Health Impact: Extending Access to Essential Medicines, Nicole Hassoun argues that the concept of a minimally good life grounds the human right to health, which in turn implies the human right to access essential medicines in developing countries. This article argues that Hassoun's argument must be revised. If the temporal unit of a minimally good life is identified, her argument faces a substantive problem, which undermines an important part of her argument. This article then proposes a solution to this problem. If this proposed solution is accepted, Hassoun's project turns out to be more radical than her argument is supposed to be.

RESUMO

The number, scale and ambition of transdisciplinary research initiatives between the global north and the global south is increasing, yet there is very little theoretical or empirical scholarship on how to lead and manage implementation to promote responsible practice. Within science, technology and innovation (STI) studies and decolonising research frameworks, and utilising collaborative autoethnography, this study codifies experience with implementing the 'Revitalising Informal Settlements and their Environments' (RISE) program (2017-2020). Our specific aim is to explore the leadership and management tensions and challenges of implementing transboundary transdisciplinary research. The findings reaffirm the importance of research leaders and managers carefully operationalising north-south research by critically reflecting on power asymmetries between disciplines, partners and locations, leveraging the potential for transdisciplinary consortia to build research capabilities in the global south, and creating a culture of reflexivity on the historical and social positionality in which research is designed, funded, implemented and evaluated. The findings foreground the role of boundary-spanning 'integrators' and 'pracademics', roles that have received little attention to date but are essential for effective delivery and societal impact beyond scientific advances. A framework for implementing north-south transdisciplinary research is outlined with five domains: (1) collaborative leadership; (2) agile management; (3) flexible consortia; (4) researcher positionality; and (5) co-design and participation. The framework can support efforts for responsibly designing and implementing large, transdisciplinary, cross-country research programs in line with ambitions for decolonising north-south research.

RESUMO

In this article, I interrogate whether the deployment and development of the Metaverse should take into account African values and modes of knowing to foster the uptake of this hyped technology in Africa. Specifically, I draw on the moral norms arising from the components of communal interactions and humanness in Afro-communitarianism to contend that the deployment of the Metaverse and its development ought to reflect core African moral values to foster its uptake in the region. To adequately align the Metaverse with African core values and thus foster its uptake among Africans, significant technological advancement that makes simulating genuine human experiences possible must occur. Additionally, it would be necessary for the developers and deployers to ensure that higher forms of spiritual activities can be had in the Metaverse to foster its uptake in Africa. Finally, I justify why the preceding points do not necessarily imply that the Metaverse will have a higher moral status than real life on the moral scale that can be grounded in Afro-communitarianism.
