The out‐of‐sight groundwater and visible but much less extensive surface waters on land constitute a linked terrestrial water system around the planet. Research is crucial for our understanding of these terrestrial water system links and interactions with other geosystems and key challenges of Earth System change. This study uses a scoping review approach to discuss and identify topical, methodological and geographical gaps and priorities for research on these links and interactions of the coupled ground‐ and surface water (GSW) system at scales of whole‐catchments or greater. Results show that the large‐scale GSW system is considered in just a small part (0.4%–0.8%) of all studies (order of 105 for each topic) of either groundwater or surface water flow, storage, or quality at any scale. While relatively many of the large‐scale GSW studies consider links with the atmosphere or climate (8%–43%), considerably fewer address links with: (a) the cryosphere or coastal ocean as additional interacting geosystems (5%–9%); (b) change drivers/pressures of land‐use, water use, or the energy or food nexus (2%–12%); (c) change impacts related to health, biodiversity or ecosystem services (1%–4%). Methodologically, use of remote sensing data and participatory methods is small, while South America and Africa emerge as the least studied geographic regions. The paper discusses why these topical, methodological and geographical findings indicate important research gaps and priorities for the large‐scale coupled terrestrial GSW system and its roles in the future of the Earth System. Plain Language Summary: The water on the land surface (surface water) and that beneath it (groundwater), along with the water that is continuously and increasingly used and managed in human societies, are connected and constitute a coherent natural‐social water system around the world. Many unknowns and open questions remain for how the small‐scale variations add up to large‐scale variability and change of this water system on land, as an integral part of the whole Earth System. Relevant research is crucial for reducing the unknowns and answering the questions, and this study's scoping review aims to assess how they have been addressed in published research so far. The aim is to identify key research gaps and priorities for further research on how the integrated water system on land functions and evolves on large scales, from whole hydrological catchments and in multiple catchments around the world up to global scale. The scoping review results show key research gaps and priorities to be the coupling of surface water and groundwater on land, and the interactions of this coupled water system with other parts and major challenges of the Earth System. Geographically, the gaps and priorities emerge as particularly large and urgent for South America and Africa. Key Points: Coupling of the ground‐surface water system is a key gap in terrestrial water research, particularly at large scalesResearch on terrestrial water interactions with other geospheres and key challenges of Earth System change is rare but impactfulMajor geographic gaps in research on the large‐scale coupled terrestrial water system emerge for South America and Africa [ABSTRACT FROM AUTHOR]

Africa's population is expected to triple by 2050, owing to rapid urbanisation and overall demographic trends. The combined pressures of urbanisation and climate change impact the ecosystem and the services it provides. As a result, additional dangers such as increased flooding, and environmental disruption have risen. Therefore, devising adaptive solutions to mitigate flood risk impacts while also building community resilience is needed. Evidence suggests that Nature‐based Solutions (NbS) can potentially alleviate floods and mitigate climate change impacts while also delivering other societal benefits. Despite rising NbS popularity following its recognition in the last decade, studies on its recognition in Africa remain limited. For this reason, this paper reviewed NbS studies conducted in East Africa (EA) to evaluate opportunities and barriers surrounding NbS adoption in EA. Academic literature published from January 2012 to May 2022 was reviewed using a comprehensive search of the SCOPUS database. Results show 14 papers have been published during the period, with the majority being post‐2020. In addition, the majority of the articles focused on cities and peri‐urban settlements, while public awareness, clear guidelines on performance monitoring, stakeholder inclusion, and diverse demonstration projects were highlighted as potential success factors for the adoption of NbS in EA.

This paper assesses the relationship between trade openness and economic growth in Africa by accounting for the heterogeneity of African countries. In addition, the paper contributes to the literature on trade openness and economic growth nexus by applying the instrumental variable panel smooth transition regression, a methodology that accounts for nonlinearity and endogeneity in the relationship between the two variables. The results of the empirical analysis reveal that the investment ratio is a channel through which trade openness affects economic growth in the African continent. In addition, the relationship between trade openness and economic growth varies according to the degree of a country's development in Africa. The study finds a negative relationship between openness and growth in low‐income countries. Conversely, for upper‐income countries, the coefficients of trade indicators are positive and statistically significant. The results indicate that African countries are not homogeneous, especially concerning trade openness and economic growth nexus. [ABSTRACT FROM AUTHOR]

The 2014 outbreak of Ebola virus disease ( EVD) in West Africa has presented a significant public health crisis to the international health community and challenged U.S. emergency departments ( EDs) to prepare for patients with a disease of exceeding rarity in developed nations. With the presentation of patients with Ebola to U.S. acute care facilities, ethical questions have been raised in both the press and medical literature as to how U.S. EDs, emergency physicians ( EPs), emergency nurses, and other stakeholders in the health care system should approach the current epidemic and its potential for spread in the domestic environment. To address these concerns, the American College of Emergency Physicians, the Emergency Nurses Association, and the Society for Academic Emergency Medicine developed this joint position paper to provide guidance to U.S. EPs, emergency nurses, and other stakeholders in the health care system on how to approach the ethical dilemmas posed by the outbreak of EVD. This paper will address areas of immediate and potential ethical concern to U.S. EDs in how they approach preparation for and management of potential patients with EVD. [ABSTRACT FROM AUTHOR]

This paper addresses bioethics in the context of the coronavirus disease 2019 (COVID‐19) pandemic. The Introduction (Section 1) highlights that at the field's inception, infectiousness was not front and center. Instead, infectious disease was widely perceived as having been conquered. This made it possible for bioethicists to center values such as individual autonomy, informed consent, and a statist conception of justice. Section 2 urges shifting to values more fitting for the moment the world is in. To find these, it directs attention to the Global South, and in particular, Africa, and to the values of ubuntu, solidarity, dignity, kinship, and humility. The paper concludes (in Section 3) that 21st‐century challenges facing bioethics are increasingly global, and calls on bioethicists themselves to be more globally inclusive in their approaches.

The Okavango Delta in southern Africa has been the subject of geomorphological and hydrological investigations since the 1970s. In the early 1990s, McCarthy and co‐workers developed a geomorphological and hydrological model which describes the processes that give rise to the gently undulating topography and the lack of saline surface water in this semi‐arid environment. This model is based on extensive investigations of soil and water chemistry conducted across the Okavango Delta, and has been subject to rigorous testing by a number of independent researchers. In their recent paper, Jolivet et al. (2023, https://doi.org/10.1029/2023GC010978) proposed an alternative hydrological model based on chemical and mineralogical analyses of samples from six auger holes drilled at a site on the lower fringe of the permanent swamp. We provide a critique of their model and explain how this model cannot describe the geohydrological functioning of the Okavango Delta. Jolivet et al. suggest there are two shallow aquifers, one hosted in sand and the other in clay‐rich material. Previous studies of subsurface soils on 18 islands have failed to reveal a deeper clay‐rich layer. Rather, the shallow groundwater is laterally fully connected and salinity varies in response to evapotranspiration. We attribute REE fractionation in subsurface soils observed by Jolivet et al. to be caused by the precipitation of calcite from groundwater which strongly accumulates REE. We are of the opinion that Jolivet et al. have insufficient data to suggest revisions to the current understanding of the functioning of the Okavango hydrological and sedimentological system. Key Points: The model proposed by Jolivet et al. cannot describe the geohydrological functioning of the Okavango DeltaPrevious studies of subsurface soils on 18 islands have failed to reveal the presumed deeper clay‐rich layerWe attribute REE fractionation in subsurface soils observed by Jolivet et al. to be caused by the precipitation of calcite from groundwater [ABSTRACT FROM AUTHOR]

Objectives: The contribution of African authors to the biomedical literature is small. We evaluated the African and non‐African scientific production published in the international literature on the COVID‐19 in Africa during the first year of the epidemic (2020). Methods: Papers on COVID‐19 in Africa were extracted from the Medline (PubMed) database for bibliometric analysis including the proportions of three leading and last authors by study type, study country, authors' and laboratories/institutions' countries of affiliation and journal ranking. Results: A total of 160 articles fulfilling the inclusion criteria were analysed. The majority (91.3%) was produced by half (53.7%) of African countries, with important regional disparities, and generally without sources of funding mentioned. The majority (>85.0) of authors in lead positions (first, second, third and last authors) were Africans. Only a small number (8.7%) of studies on COVID‐19 in Africa were carried out by laboratories not on the African continent (mainly Europe, USA and China) and generally received funding. The last and first authors were more frequently of non‐African origin in journals with an Impact Factor ranking ≥1, and more frequently of African origin in journals with a lower ranking (< 1). The first and last non‐African authors tended to report their studies in high ranking ≥1 journals. Conclusions: Our study demonstrates that the emergence of promising African research capable of publishing in indexed but low‐impact factor medical journals and reveals the persistence of a North‐South asymmetry in international cooperation in biomedical research with Africa.

Introduction: Social protection programmes are considered HIV‐sensitive when addressing risk, vulnerability or impact of HIV infection. Socio‐economic interventions, like livelihood and employability programmes, address HIV vulnerabilities like poverty and gender inequality. We explored the HIV‐sensitivity of socio‐economic interventions for unemployed and out‐of‐school young women aged 15 to 30 years, in East and Southern Africa, a key population for HIV infection. Methods: We conducted a systematic review using a narrative synthesis method and the Mixed Methods Appraisal Tool for quality appraisal. Interventions of interest were work skills training, microfinance, and employment support. Outcomes of interest were socio‐economic outcomes (income, assets, savings, skills, (self‐) employment) and HIV‐related outcomes (behavioural and biological). We searched published and grey literature (January 2005 to November 2019; English/French) in MEDLINE, Scopus, Web of Science and websites of relevant international organizations. Results: We screened 3870 titles and abstracts and 188 full‐text papers to retain 18 papers, representing 12 projects. Projects offered different combinations of HIV‐sensitive social protection programmes, complemented with mentors, safe space and training (HIV, reproductive health and gender training). All 12 projects offered work skills training to improve life and business skills. Six offered formal (n = 2) or informal (n = 5) livelihood training. Eleven projects offered microfinance, including microgrants (n = 7), microcredit (n = 6) and savings (n = 4). One project offered employment support in the form of apprenticeships. In general, microgrants, savings, business and life skills contributed improved socio‐economic and HIV‐related outcomes. Most livelihood training contributed positive socio‐economic outcomes, but only two projects showed improved HIV‐related outcomes. Microcredit contributed little to either outcome. Programmes were effective when (i) sensitive to beneficiaries' age, needs, interests and economic vulnerability; (ii) adapted to local implementation contexts; and (iii) included life skills. Programme delivery through mentorship and safe space increased social capital and may be critical to improve the HIV‐sensitivity of socio‐economic programmes. Conclusions: A wide variety of livelihood and employability programmes were leveraged to achieve improved socio‐economic and HIV‐related outcomes among unemployed and out‐of‐school young women. To be HIV‐sensitive, programmes should be designed around their interests, needs and vulnerability, adapted to local implementation contexts, and include life skills. Employment support received little attention in this literature. [ABSTRACT FROM AUTHOR]

Global, continental and regional maps of concentrations, stocks and fluxes of natural resources provide baseline data to assess how ecosystems respond to human disturbance and global warming. They are also used as input to numerous modelling efforts. But these maps suffer from multiple error sources and, hence, it is good practice to report estimates of the associated map uncertainty so that users can evaluate their fitness for use.We explain why quantification of uncertainty of spatial aggregates is more complex than uncertainty quantification at point support because it must account for spatial autocorrelation of the map errors. Unfortunately, this is not done in a number of recent high‐profile studies. We describe how spatial autocorrelation of map errors can be accounted for with block kriging, a method that requires geostatistical expertise. Next, we propose a new, model‐based approach that avoids the numerical complexity of block kriging and is feasible for large‐scale studies where maps are typically made using machine learning. Our approach relies on Monte Carlo integration to derive the uncertainty of the spatial average or total from point support prediction errors. We account for spatial autocorrelation of the map error by geostatistical modelling of the standardized map error.We show that the uncertainty strongly depends on the spatial autocorrelation of the map errors. In a first case study, we used block kriging to show that the uncertainty of the predicted topsoil organic carbon in France decreases when the support increases. In a second case study, we estimated the uncertainty of spatial aggregates of a machine learning map of the above‐ground biomass in Western Africa using Monte Carlo integration. We found that this uncertainty was small because of the weak spatial autocorrelation of the standardized map errors.We present a tool to get realistic estimates of the uncertainty of spatial averages and totals of natural resource maps. The method presented in this paper is essential for parties that need to evaluate whether differences in aggregated environmental variables or natural resources between regions or over time are statistically significant.

Previous studies on wind turbine and wind farm optimization for Levellized cost of energy (LCOE) and annual energy production (AEP) have focused on horizontal axis wind turbines (HAWT) and vertical axis wind turbines (VAWT). Regions with lower wind speed resources tend to have a higher levellized cost of energy and lower annual energy production. In this paper, the authors investigate the optimization of a novel, Ferris wheel wind turbine (FWT) for low wind speed regions of Africa. The research used an Excel‐based Multi‐Objective Optimization (EMOO) model. The EMOO program has both binary‐coded and real‐coded Elitist Non‐Dominated Sorting Genetic Algorithm (NSGA‐II). The optimization is conducted by studying the effect of varying the rim diameter, number of blades, and the rated wind speeds for an 800‐kW generator on the performance and economics in 21 African cities. The results show that, on average, the return‐on‐investment increases over the base design by up to 182%, and both the simple payback period (SPP) and the levellized cost of electricity decreased by 39% as the rim diameter increases combined with a 50% reduction in blade numbers. In addition, a 75% reduction in blade numbers caused a further 32% decrease on average for both the simple payback period and the levellized cost of electricity. [ABSTRACT FROM AUTHOR]

To protect nature, African parks must contribute to human well‐being, overcome threats, and secure reliable funding sources. The first Africa Protected Areas Congress (APAC) held in Kigali, Rwanda from July 18 to 23, 2022 has reaffirmed the need to re‐imagine the role of protected and conserved areas (PCAs) in safeguarding wildlife and biodiversity on the continent. Conservation strategies in Africa must be driven by the urgency to make PCAs people centered, advance integrated approaches to tackle drivers of biodiversity loss, and to promote sustainable and innovative financing for PCAs. This paper discusses how African countries can address these needs to harness the full potential of PCAs and ensure their long‐term sustainability. [ABSTRACT FROM AUTHOR]

Southern Africa harbors exceptional biodiversity that is increasingly threatened by climate change, land use, and other pressures. However, risks to the regional ecosystems and quality and consistency of adaptation strategies remain understudied, making conservation and restoration efforts challenging. Here, we reviewed scientific articles published during the period 2000–2020, which (1) addressed observed and projected impacts of climate change on different species, populations, and ecosystems in nine southern African countries, and (2) formulated management and policy responses aiming to mitigate these impacts. We identified and evaluated 28 papers meeting these search criteria. We found that the three components of our investigation, that is, ecosystem type, type of impact, and management and policy responses, were covered by research rather fragmentarily. However, the reviewed publications addressed a large variety of species and ecosystems and a variety of processes, from local extinction, range contraction, and increased mortality to modified inter‐specific interactions. The identified human responses included active vegetation and animal management, improved conservation policies, and monitoring. Most of the publications highlighted severe data limitations, lacking coordination of conservation policies, and insufficient consideration of transient environmental conditions in management and policy planning. We conclude that the current level of understanding of climatic threats to species and ecosystems is limited in southern Africa, and new coordinated research and monitoring actions are needed. This review characterized the high diversity of climate change risks to ecosystems and related social responses, potentially helping to attract further research attention and inform regional adaptation strategies.

This paper assesses the performances of runoff (Ro) and runoff coefficient (α, the ratio of runoff to precipitation) simulations from 23 models during the historical period and then projects their future changes under the two emission scenarios (SSP1‐2.6 and SSP5‐8.5) in the Coupled Model Intercomparison Project. Compared with the UNH/GRDC Ro dataset (0.82 mm day−1), the multi‐model median (MME) Ro of 1995–2014 produces a comparable global mean magnitude (0.80 mm day−1), displays a similar spatial distribution of mean Ro, and also well captures the seasonal cycles at both global and basin scales. The global mean Ro of MME is projected to be increased by 0.01–0.02 mm day−1 (SSP1‐2.6) and 0.02–0.10 mm day−1 (SSP5‐8.5) during the twenty‐first century. Regional hotspots for strong increasing Ro appear across most areas of northern high latitudes, Africa, and southeastern Asia, with high inter‐model consistency. The global mean α is projected to be slightly decreased (−0.17 to −0.63%) except for the long‐term under the SSP5‐8.5 (0.26%). Although signs of changes in Ro vary with the river basins, periods, and scenarios, α in more than half (7 out of 12) river basins are projected to decrease. The uneven distributions of projected Ro changes over global land areas are related to the response of multiple hydroclimatic variables to the global warming. Given regions with inconstancy change signs of the projected precipitation, we speculate that changes in Ro are affected by more complicated hydroclimatic processes that warrant further investigations with physical‐based approaches. Plain Language Summary: Evidence has indicated that the terrestrial hydrology would be changed unevenly over global land areas under a warmer climate. Runoff (Ro) is one of the key components of the land water budget and it represents the natural freshwater resource on the earth. This study assesses the historical simulation performances and then projects future changes in Ro and α (the ratio of runoff to precipitation) under two emission scenarios (i.e., SSP1‐2.6 and SSP5‐8.5) based on the simulations from 23 CMIP6 models. The results show that the multi‐model median Ro during the historical period is highly consistent with the reference dataset and captures the seasonal variation in most river basins. During the twenty‐first century, the multi‐model median of global mean Ro is overall projected to increase in the future and the α would slightly decrease except for the long‐term under the SSP5‐8.5. While signs and magnitudes of projection changes depend on regions and basins, those changes are more evident under higher warming levels. The uneven distributions of projected changes of Ro over global land areas are related to the response of other land surface hydrological variables to the global warming induced by anthropogenic emissions in climate models. Key Points: The runoff (Ro) and runoff coefficient (α) in CMIP6 are assessed and their future changes are projected under two SSPs in global and basin scalesThe global mean magnitude, spatial pattern, and seasonal cycles over most river basins are well reproduced by multi‐model median RoThe global mean Ro (α) is projected to increase (decrease), but their projections vary with basins and scenarios [ABSTRACT FROM AUTHOR]

Interventions in Africa designed to stop biodiversity decline have often failed because they were based on a top‐down approach to management and focused on enforcing restrictive rules and imposing bans. They were equally misaligned with the values and needs of local actors. This paper presents an African perspective on the discourse regarding the bushmeat crisis and shows that bushmeat in Africa goes beyond being a source of livelihood, having a multifaceted use that must be considered when designing interventions. We show that current conservation initiatives often do not address the right issues, by neglecting nonmonetary dimensions of bushmeat use, inadequately planning interventions, failing to align wildlife laws with realities on the ground, and carrying out ineffective law enforcement characterized by poor governance and corruption. We recommend a revision of current legal frameworks to enhance local ownership, tenure rights, and the sustainable economic empowerment of local communities to reduce hunting. We also call for development of regionally led innovative programs that invest in nature‐based solutions and payments for environmental services. Finally, we identify where more research is needed to understand why wildlife use in Africa is overlooked in national development policies and not considered in national accounting.

Scavenging is widespread in the carnivore guild and can greatly impact food web structures and population dynamics by either facilitation or suppression of sympatric carnivores. Due to habitat loss and fragmentation, carnivores are increasingly forced into close sympatry, possibly resulting in more interactions such as kleptoparasitism and competition. In this paper, we investigate the potential for these interactions when carnivore densities are high. A camera trap survey was conducted in central Tuli, Botswana, to examine leopard Panthera pardus densities and spatiotemporal activity patterns of leopard and its most important competitors' brown hyena Parahyaena brunnea and spotted hyena Crocuta crocuta. Spatial capture–recapture models estimated leopard population density to be 12.7 ± 3.2 leopard/100 km2, which is one of the highest leopard densities in Africa. Time‐to‐event analyses showed both brown hyena and spotted hyena were observed more frequently before and after a leopard observation than expected by chance. The high spatiotemporal overlap of both hyena species with leopard is possibly explained by leopard providing scavenging opportunities for brown hyena and spotted hyena. Our results suggest that central Tuli is a high‐density leopard area, despite possible intense kleptoparasitism and competition. [ABSTRACT FROM AUTHOR]

Bats are the natural reservoir host for many pathogenic and non‐pathogenic viruses, potentially spilling over to humans and domestic animals directly or via an intermediate host. The ongoing COVID‐19 pandemic is the continuation of virus spillover events that have taken place over the last few decades, particularly in Asia and Africa. Therefore, these bat‐associated epidemics provide a significant number of hints, including respiratory cellular tropism, more intense susceptibility to these cell types, and overall likely to become a pandemic for the next spillover. In this systematic review, we analysed data to insight, through bat‐originated spillover in Asia and Africa. We used STATA/IC‐13 software for descriptive statistics and meta‐analysis. The random effect of meta‐analysis showed that the pooled estimates of case fatality rates of bat‐originated viral zoonotic diseases were higher in Africa (61.06%, 95%CI: 50.26 to 71.85, l2% = 97.3, p < 0.001). Moreover, estimates of case fatality rates were higher in Ebola (61.06%; 95%CI: 50.26 to 71.85, l2% = 97.3, p < 0.001) followed by Nipah (55.19%; 95%CI: 39.29 to 71.09, l2% = 94.2, p < 0.001), MERS (18.49%; 95%CI: 8.19 to 28.76, l2% = 95.4, p < 0.001) and SARS (10.86%; 95%CI: 6.02 to 15.71, l2% = 85.7, p < 0.001) with the overall case fatality rates of 29.86 (95%CI: 29.97 to 48.58, l2% = 99.0, p < 0.001). Bat‐originated viruses have caused several outbreaks of deadly diseases, including Nipah, Ebola, SARS and MERS in Asia and Africa in a sequential fashion. Nipah virus emerged first in Malaysia, but later, periodic outbreaks were noticed in Bangladesh and India. Similarly, the Ebola virus was detected in the African continent with neurological disorders in humans, like Nipah, seen in the Asian region. Two important coronaviruses, MERS and SARS, were introduced, both with the potential to infect respiratory passages. This paper explores the dimension of spillover events within and/or between bat–human and the epidemiological risk factors, which may lead to another pandemic occurring. Further, these processes enhance the bat‐originated virus, which utilises an intermediate host to jump into human species. [ABSTRACT FROM AUTHOR]

The paper reflects on the lessons from two case studies in order to discuss (1) how they address Ostrom's eight principles and (2) implications for social, economic and environmental challenges. The two case studies are of forest communities in Venda in South Africa and Ciptagelar, West Java, discussed in terms of their social, environmental and economic approaches. In both cases, the communities see themselves as related to nature; in the case of Venda, they express this as a totemic relationship and have been inspired to apply an ecological calendar that was taught to them during the time Mphatheleni Makaulule spent learning from Amazonian leaders. In the case of Ciptagelar, the nomadic way of life is based on a sense of being stewards who do not commodify rice, a sacred source of life, which is in turn dependent upon all the co‐existent creatures and ultimately the forest, which is their home. In both communities, the environment and people are priorities managed by observing the natural cycle. In both communities, an ecological calendar guides the planning and harvesting of crops. In Tshidzivhe Venda, a rigorous approach to crops, harvesting from the forest and re‐planting the forest, is observed, and the entire community act as caretakers and are required to ask permission before harvesting from the forest. In Ciptagelar, West Java, the chief reads the signs when it is time to move to another area and follows a careful approach to biodiversity ensuring that paddy is grown only for certain months so that other creatures can thrive in other months. The Balancing Individualism and Collectivism Special Integration Group has focused on learning by doing using an applied mixed methods approach. It is based on a community of practice spanning NGOs, community projects and university departments. It is supported by a small NRF fund, some funding from UNISA and in kind support from participants. We work together because of shared values and mutual respect. [ABSTRACT FROM AUTHOR]

This paper examines how development actors within the Ghanaian agricultural sector enact information and communication technology (ICT) in their day‐to‐day outreach practices with smallholder farmers. We draw on an in‐depth qualitative case study, informed by the theoretical perspective of "strategy‐as‐practice" to answer the research question: "what ICT‐mediated strategic practices are used by development actors in the Ghanaian agriculture sector?" The research findings reveal that (1) the activities of development actors are meshed within a network of interdependencies; (2) the enacted strategic practices reflect the trade‐off between novelty of content and novelty of the technologies used to deliver it; and lastly, (3) the praxis of development actors for doing ICT for development consists of hybrid strategies, combining bottom‐up approaches consistent with farmers' indigenous smallholder logic, with top‐down imperatives framing agriculture "as a business" and nurturing value‐chain integration. Consequently, our research points to the impact of ICT initiatives as step‐wise and attained over the long term, rather than disruptive and attained in the immediate term. [ABSTRACT FROM AUTHOR]

Capacity building programmes for African regulators should link education, training and research with career development in an approach that combines an academic base and experiential learning aligned within a competency framework. A regulatory ecosystem that engages with a broad range of stakeholders will mean that expertise in the ever‐expanding field of regulatory science filters into teaching and research in a symbiotic way. In this way capacity development interventions will be a collaborative approach between the learning context (academic and training institutions) and the performance context (regulatory agencies and industry), which will ultimately best serve the patients. Monitoring and evaluation of capacity development interventions will be essential to show value of investments and ultimately guide continued funding and sustainability. This paper reviews the skills and human capacity gaps, reports on regulatory assessment pathways used in Ghana, South Africa and Zimbabwe and outlines a staged tactical approach for Africa that builds on previous efforts to strengthen African regulatory ecosystems.

Historical research on the race between education and technology has focused on the West but barely touched upon 'the rest'. A new occupational wage database for 50 African and Asian economies allows us to compare long‐run patterns in skill premiums across the colonial and post‐colonial eras (c. 1870–2010). Our data reveal three major patterns. First, skilled labour was considerably more expensive in colonial Africa and Asia than in pre‐industrial Europe. Second, skill premiums were distinctly higher in Africa than in Asia. Third, in both regions, skill premiums fell dramatically over the course of the twentieth century, ultimately converging to levels long observed in the West. Our paper takes a first step to explain both the origins of the Africa–Asia gap and the drivers of global skill premium convergence, paying special attention to the colonial context that shaped demand, supply, and labour market institutions.

Using a novel dataset on foreign direct investment (FDI), this paper analyzes the correlates of planned FDI in the food and beverages sector in 49 African countries over the period 2003–2017. It applies the random effects model and augments the standard specification of FDI determinants with a set of factors related to the agricultural sector performance, hypothesized to be essential from the perspective of supply chain linkages and access to raw materials. The results indicate that well‐performing and well‐capitalized agricultural sector of the host country is a key factor associated with the choice of investment location by foreign investors, especially those from the Global North. Capital investment in agriculture, as proxied by agricultural gross fixed capital formation and net capital stock, is particularly important. Public investment in agriculture, in the form of government expenditure and official development assistance, is also associated with higher FDI. These factors, however, are not significant in case of the least developed countries where only market potential appears to matter for foreign investors. The results suggest that complementarities may exist between different types of investments and that policy‐makers willing to attract food and beverages FDI should prioritize agricultural sector development. [EconLit Citations: E22, E24, F21, F23, Q00, Q13, Q18]. Practitioner points: Planned FDI in the food and beverages sector in Africa are driven by the potential that a domestic emerging consumer class represents and investors choose large and fast‐growing markets.Well‐performing and well‐capitalized agricultural sector of the host country appears to be a key factor associated with the choice of investment location by foreign investors, especially those from the Global North. Capital investment in agriculture, as proxied by agricultural gross fixed capital formation and net capital stock, is particularly important.The results suggest that complementarities may exist between different types of investments and that policy‐makers willing to attract food and beverages FDI should prioritize agricultural sector development.In the least developed countries in Africa, only the market potential, as reflected by both the market size and its dynamics, is associated with higher FDI, while the evidence is missing for the agricultural sector performance indicators.

In their recent article, Sawers and Stillwaggon critique the "concurrency hypothesis" on a number of grounds. In this commentary, I focus on one thread of their argument, pertaining to the evidence derived from modelling work. Their analysis focused on the foundational papers of Morris and Kretzschmar; here, I explore the research that has been conducted since then, which Sawers and Stillwaggon leave out of their review. I explain the methodological limitations that kept progress on the topic slow at first, and the various forms of methodological development that were pursued to overcome these. I then highlight recent modelling work that addresses the various limitations Sawers and Stillwaggon outline in their article. Collectively, this line of research provides considerable support for the modelling aspects of the concurrency hypothesis, and renders their critique of the literature incomplete and obsolete. It also makes clear that their call for "an end (or at least a moratorium) to research on sexual behaviour in Africa" that pertains to concurrency is unjustified. [ABSTRACT FROM AUTHOR]

This paper explores ethical considerations for active studies of circumcision, i.e., the amputation of the foreskin, in the form of a case study of three major trials performed in African countries in the early 2000s. The paper outlines the function of the foreskin and method and history of its amputation as well as its current use in attempting to combat the global AIDS crisis. These trials are then interrogated in accordance with the Declaration of Helsinki. In particular, the irreversible nature of amputation is given great consideration. The case studies are found to have serious failures in terms of the modern iteration of the Declaration of Helsinki. This paper calls for extreme scrutiny in accordance with international norms relating to the ethical treatment of human subjects in a research context of studies of circumcision if and when they are proposed again.

The complexity and magnitude of threats to black (Diceros bicornis) and white (Ceratotherium simum) rhinoceros conservation in Africa have triggered global concerns and actions. In this study, we analyzed (i) threats to rhinoceros conservation including external shocks, (ii) historical rhinoceros conservation strategies in Zimbabwe and Africa, more broadly, and (iii) opportunities for enhanced rhinoceros conservation in Zimbabwe and Africa. A literature search from 1975 to 2020 was carried out using a predefined search protocol, involving a number of filters based on a set of keywords to balance search sensitivity with specificity. A total of 193 articles, which were most relevant to key themes on rhinoceros conservation, were used in this study. The common threats to rhinoceros conservation identified in this paper include poaching, habitat fragmentation and loss, international trade in illegal rhino products, and external shocks such as global financial recessions and pandemics. Cascading effects emanating from these threats include small and isolated populations, which are prone to genetic, demographic, and environmental uncertainties. Rhinoceros conservation strategies being implemented include education and awareness campaigns, better equipped and more antipoaching efforts, use of innovative systems and technologies, dehorning, and enhancing safety nets, and livelihoods of local communities. Opportunities for rhinoceros conservation vary across the spatial scale, and these include (a) a well‐coordinated stakeholder and community involvement, (b) strategic meta‐population management, (c) enhancing law enforcement initiatives through incorporating real‐time surveillance technologies and intruder detection sensor networks for crime detection, (d) scaling up demand reduction awareness campaigns, and (e) developing more certified wildlife crime and forensic laboratories, and information repository for international corporation.

Externalities, such as air pollution and increased occupational hazards, resulting from global trends in climate change, rapid industrialization, and rapidly increasing populations are raising global concerns about the associated health risks. The Global Environmental and Occupational Health Hub for Eastern Africa was established to address some of these problems at national and regional levels through focused training and applied research that would yield evidence supporting policies and investments to mitigate risks of increasing environmental threats throughout the Eastern African region. Emphasis has been placed on air pollution, a leading risk factor for global mortality, accounting for over 7 million premature deaths or 8.7% of the 2017 global mortality burden. Despite the enormous disease burden that air pollution causes, global investment in air pollution monitoring and research capacity building in low‐middle and middle‐income countries have been inadequate. This study outlines the activities the Hub has undertaken in planning for and carrying out its initial capacity building and building its primary research programs and identifies central lessons that can inform other large global research partnerships. Plain Language Summary: Air pollution and increased occupational hazards resulting from climate change and rapid industrialization are damaging health. The Global Environmental and Occupational Health (GEOHealth) Hub for Eastern Africa was established to address some of these problems at national and regional levels through training and applied research. This paper describes the activities the Hub has undertaken during its first five years and identifies central lessons that can inform other large global research partnerships. Key Points: Environmental and occupational health challenges remain significant throughout Eastern AfricaThe Eastern Africa GEOHealth Hub is well positioned to build its research and dissemination activitiesThe Hub serves as a model for other large, international research collaborations [ABSTRACT FROM AUTHOR]

This study analyses an implementation of a government accounting reform in Benin directed at redressing fraudulent and corrupt practices. Although reforms to improve public administration and to mitigate corruption in Africa often have disappointing outcomes, our case study involving systems for payment of supplier invoices, payroll matters, and debt certificates had encouraging findings. The systems reduced inefficiencies and corrupt practices. An "enabling environment" (its main elements being emancipatory space, empowered participation, and ethical leadership) encouraged the deeper involvement of committed, expert, and ethical local civil servants in establishing effective financial controls. In the context of anticorruption reforms, this illustrates that public sector organizations in Africa should not invariably be regarded as monolithic bureaucratic top‐down entities, staffed by civil servants who are either passive "bystanders," purely self‐interested "players," or insufficiently expert, and hence in need for more training, and of imported, expensive, accounting systems implemented by foreign consultants. In contrast, the paper argues that, within a suitable environment, granting indigenous experts enough latitude to enact incremental yet substantive accounting changes at the local level may be more effective.

Short‐term global ensemble predictions of rainfall currently have no skill over northern tropical Africa when compared to simple climatology‐based forecasts, even after sophisticated statistical postprocessing. Here, we demonstrate that 1‐day statistical forecasts for the probability of precipitation occurrence based on a simple logistic regression model have considerable potential for improvement. The new approach we present here relies on gridded rainfall estimates from the Tropical Rainfall Measuring Mission for July‐September 1998–2017 and uses rainfall amounts from the pixels that show the highest positive and negative correlations on the previous two days as input. Forecasts using this model are reliable and have a higher resolution and better skill than climatology‐based forecasts. The good performance is related to westward propagating African easterly waves and embedded mesoscale convective systems. The statistical model is outmatched by the postprocessed dynamical forecast in the dry outer tropics only, where extratropical influences are important. Plain Language Summary: Forecasts of precipitation for the next few days based on state‐of‐the‐art weather models are currently inaccurate over northern tropical Africa, even after systematic forecast errors are corrected statistically. In this paper, we show that we can use rainfall observations from the previous 2 days to improve 1‐day predictions of precipitation occurrence. Such an approach works well over this region, as rainfall systems tend to travel from the east to the west organized by flow patterns several kilometers above the ground, called African easterly waves. This statistical forecast model requires training over a longer time period (here 19 years) to establish robust relationships on which future predictions can be based. The input data employed are gridded rainfall estimates based on satellite data for the African summer monsoon in July to September. The new method outperforms all other methods currently available on a day‐to‐day basis over the region, except for the dry outer tropics, where influences from midlatitudes, which are better captured by weather models, become more important. Key Points: Raw and statistically postprocessed global ensemble forecasts fail to predict West African rainfall occurrenceA logistic regression model using observations from preceding days outperforms all other types of forecastsThe skill of the statistical model is mainly related to propagating African easterly waves and mesoscale convective systems [ABSTRACT FROM AUTHOR]

Within conservation science and practice, community‐based conservation (CBC) includes policy and management interventions incorporating engagement or participation of local communities and resource users. Evidence across scales points to the importance of supporting local actors and management institutions for better social and ecological outcomes of CBC interventions. However, the institutional and governance processes underlying CBC outcomes remain poorly understood, specifically how institutions respond to opportunities and constraints posed by CBC. In response, this special issue of Conservation Science & Practice solicited contributions investigating adaptation and evolution of institutions and governance in CBC. In this paper, we introduce the special issue and its 13 contributions, representing cases from Africa, Asia, and the Americas across organizational scales and resource systems. We assess the state of knowledge of CBC, identify common themes and lessons learned, and suggest future priorities for research and practice. [ABSTRACT FROM AUTHOR]

Tarentola annularis is a climbing gecko with a wide distribution in Africa north of the equator. In the present paper, we describe the development of the osteocranium of this lizard, from the first appearance of the cranial elements up to the point of hatching. This is based on a combination of histology and cleared and stained specimens. This is the first comprehensive account of gekkotan pre‐hatching skull development based on a comprehensive series of embryos, rather than a few selected stages. Given that Gekkota is now widely regarded as representing the sister group to other squamates, this account helps to fill a significant gap in the literature. Moreover, as many authors have considered features of the gekkotan skull and skeleton to be indicative of paedomorphosis, it is important to know whether this hypothesis is supported by delays in the onset of cranial ossification. In fact, we found the sequence of cranial bone ossification to be broadly comparable to that of other squamates studied to date, with no significant lags in development. [ABSTRACT FROM AUTHOR]

Background: The development of the face occurs during the early days of intrauterine life by the formation of facial processes from the first Pharyngeal arch. Derangement in these well‐organized fusion events results in Orofacial clefts (OFC). Van der Woude syndrome (VWS) is one of the most common causes of syndromic cleft lip and/or palate accounting for 2% of all cases. Mutations in the IRF6 gene account for 70% of cases with the majority of these mutations located in the DNA‐binding (exon 3, 4) or protein‐binding domains (exon 7–9). The current study was designed to update the list of IRF6 variants reported for VWS by compiling all the published mutations from 2013 to date as well as including the previously unreported VWS cases from Africa and Puerto Rico. Methods: We used PubMed with the search terms; "Van der Woude syndrome," "Popliteal pterygium syndrome," "IRF6," and "Orofacial cleft" to identify eligible studies. We compiled the CADD score for all the mutations to determine the percentage of deleterious variants. Results: Twenty‐one new mutations were identified from nine papers. The majority of these mutations were in exon 4. Mutations in exon 3 and 4 had CADD scores between 20 and 30 and mutations in exon 7–9 had CADD scores between 30 and 40. The presence of higher CADD scores in the protein‐binding domain (exon 7–9) further confirms the crucial role played by this domain in the function of IRF6. In the new cases, we identified five IRF6 mutations, three novel missense mutations (p.Phe36Tyr, p.Lys109Thr, and p.Gln438Leu), and two previously reported nonsense mutations (p.Ser424*and p.Arg250*). Conclusion: Mutations in the protein and DNA‐binding domains of IRF6 ranked among the top 0.1% and 1% most deleterious genetic mutations, respectively. Overall, these findings expand the range of VWS mutations and are important for diagnostic and counseling purposes. [ABSTRACT FROM AUTHOR]

Increasing pressure is being exerted on the peri‐urban space that has elevated the demand for electricity, affects the global water resource, and impacts the potential to produce food, fiber, and commodity products. Algae‐based technologies and in particular algae‐based sewage treatment provides an opportunity for recovery of water for recycle and re‐use, sequestration of greenhouse gases, and generation of biomass. Successful coupling of municipal sewage treatment to an algae‐to‐energy facility depends largely on location, solar irradiance, and temperature to achieve meaningful value recovery. In this paper, an algae‐to‐energy sewage treatment system for implementation in southern Africa is elaborated. Using results from the continued operation of an integrated algal pond system (IAPS), it is shown that this 500‐person equivalent system generates 75 kL per day water for recycle and re‐use and, ∼9 kg per day biomass that can be converted to methane with a net energy yield of ∼150 MJ per day, and ∼0.5 kL per day of high nitrogen‐containing liquid effluent (>1 g/L) with potential for use as organic fertilizer. It is this opportunity that IAPS‐based algae‐to‐energy sewage treatment provides for meaningful energy and co‐product recovery within the peri‐urban space and, which can alleviate pressure on an already strained water–energy–food nexus.

In this paper, we study supplier-firm interactions to explain firms' outsourcing relationships. We show that in an imperfect information setup a firm learns about the quality of its suppliers through repeated interaction. As the firm determines the suppliers' quality with greater precision, it gives a greater proportion of its contracts to these ‘better’ suppliers. We report evidence from African manufacturing firms that is consistent with our hypothesis: both frequency and volume of transactions increase with the length of a firm's relationship with its supplier. These effects are stronger in poor contracting environments. [ABSTRACT FROM AUTHOR]

Glaciation accompanied our human ancestors in Africa throughout the Pleistocene. Regrettably, equatorial glaciers and snow are disappearing rapidly, and we are likely the last generation who will get to know these peculiar places. Despite the permanently harsh conditions of glacier/snow habitats, they support a remarkable diversity of life ranging from bacteria to animals. Numerous papers have been devoted to microbial communities and unique animals on polar glaciers and high mountains, but only two reports relate to glacial biodiversity in equatorial regions, which are destined to melt completely within the next few decades. Equatorial glaciers constitute "cold islands" in tropics, and discovering their diversity might shed light on the biogeography, dispersal, and history of psychrophiles. Thus, an opportunity to protect biota of equatorial glaciers hinges on ex situ conservation. It is timely and crucial that we should investigate the glacial biodiversity of the few remaining equatorial glaciers. [ABSTRACT FROM AUTHOR]

This paper revisits the inverse farm size-productivity relationship in Kenya. The study makes two contributions. First, the relationship is examined over a much wider range of farm sizes than most studies, which is particularly relevant in Africa given the recent rise of medium- and large-scale farms. Second, we test the inverse relationship hypothesis using three different measures of productivity including profits per hectare and total factor productivity, which are arguably more meaningful than standard measures of productivity such as yield or gross output per hectare. We find a U-shaped relationship between farm size and all three measures of farm productivity. The inverse relationship hypothesis holds on farms between zero and 3 hectares. The relationship between farm size and productivity is relatively flat between 3 and 5 hectares. A strong positive relationship between farm size and productivity emerges within the 5 to 70 hectare range of farm sizes. Across virtually all measures of productivity, farms between 20 and 70 hectares are found to be substantially more productive than farms under 5 hectares. When the analysis is confined to fields cultivated to maize (Kenya's main food crop) the productivity advantage of relatively large farms stems at least partially from differences in technical choice related to mechanization, which substantially reduces labor input per hectare, and from input use intensity.

This paper investigates the within‐country location choices of a large sample of foreign and domestic firms in 19 Sub‐Saharan African countries. We show that foreign firms are more likely to locate in core regions compared to domestic ones but generate significantly more jobs per productive unit in the periphery. We find some evidence that foreign firms generate relatively better jobs in peripheral areas: more skill intensive and better paid. These results highlight a fundamental role that FDI in peripheral areas might play in rebalancing the spatial distribution of economic opportunities in developing countries where highly congested megacities exercise a strong centripetal force.

Much theorizing has been done about the African food crisis. This paper reviews a gendered approach to agriculture, focusing on the implications of labor differentiation, incentives, and struggles over access to resources for agricultural development. The paper then analyzes two approaches to understanding Africa's development crises. One focuses on faulty incentives created in statist strategies and the other on an uncaptured peasantry; both approaches are oblivious to gender labor relations. The paper concludes with policy implications. [ABSTRACT FROM AUTHOR]

Abstract: Despite significant donor funding, government accounting reforms seeking transparent and effective management of public resources often fail or have limited success, especially in Africa, prompting questions about donors’ implementation approach and calls for studies of successful reforms. This paper investigates a local government accounting reform in Benin supported by a German development agency–perceived as successful due to the participatory, pragmatic, and incremental approach reinforced by conditionalities in the face of neo‐patrimonial leadership.

The greater Lake Victoria region was the focus of the ‘HIGH Weather impact lAke sYstem’ project, with the aim of developing an early warning capability for hazardous weather. Strong thunderstorm outflows can cause boats to capsize and lead to drowning. Lightning is also a hazard to fishermen, and over land flash flooding from heavy rainfall is a significant hazard. Between March and October 2019, 16 regional warnings were issued, and 14 days had reported impacts. Only one of the issued warnings aligned with any reported impacts. The issued warnings were verified using three different methodologies and found to have a very low frequency bias, confirming that too few warnings are being issued, especially for precipitation. The skill of the warnings based on the probability of detection and symmetric extremal dependency index was also found to be low. Potential warnings days are derived from individual and multivariate combinations of numerical weather prediction forecasts of mean wind speed, precipitation and a new lightning diagnostic from the 4.4 km Tropical Africa configuration of the Met Office Unified Model. The methodology identified 5-7 times the issued number of warnings, including 50% of days with reported impacts and 25% of days with issued warnings. Overall, 70%-80% of the identified potential warning days appear to be justified, suggesting that for this period not enough warnings were issued. It is shown that a daily aggregate of the lightning diagnostic is a skilful addition to any guidance supporting a decision-making process [ABSTRACT FROM AUTHOR]

Conservation areas encompassing elevation gradients are biodiversity hotspots because they contain a wide range of habitat types in a relatively small space. Studies of biodiversity patterns along elevation gradients, mostly on small mammal or bird species, have documented a peak in diversity at mid elevations. Here, we report on a field study of medium and large mammals to examine the impact of elevation, habitat type, and gross primary productivity on community structure. Species richness was observed using a camera trap transect with 219 sites situated across different habitat types from 2329 to 4657 m above the sea level on the western slope of Mt Kenya, the second highest mountain in Africa. We found that the lowest elevation natural habitats had the highest species richness and relative abundance and that both metrics decreased steadily as elevation increased, paralleling changes in gross primary productivity, and supporting the energy richness hypothesis. We found no evidence for the mid‐domain effect on species diversity. The lowest elevation degraded Agro‐Forestry lands adjacent to the National Park had high activity of domestic animals and reduced diversity and abundance of native species. The biggest difference in community structure was between protected and unprotected areas, followed by more subtle stepwise differences between habitats at different elevations. Large carnivore species remained relatively consistent but dominant herbivore species shifted along the elevation gradient. There was some habitat specialization and turnover in species, such that the elevation gradient predicts a high diversity of species, demonstrating the high conservation return for protecting mountain ecosystems for biodiversity conservation.

This study investigates meteorological drought in sub‐Saharan Africa within the context of elephant conservation. Prolonged drought significantly impacts elephants, leading to increased mortality rates and heightened human–elephant conflicts. We assess both the anticipated 21st century changes in impact‐relevant meteorological drought metrics and the efficacy of existing forecasting systems in predicting such droughts on seasonal time scales. The climate change element of our study uses the 6th Coupled Model Intercomparison Project (CMIP6) ensemble to evaluate projected change in 3‐month Standardized Precipitation Index (SPI3). We then carry out a quantitative assessment of seasonal forecast skill, utilizing 110 years of precipitation hindcasts generated by the European Centre for Medium Range Forecasting (ECMWF) system. Our findings indicate that persistent drought is projected to become more frequent over the 21st century in southern Africa, where the majority of elephants reside. Analysis of seasonal hindcasts indicates that, while the forecasts have greater skill than climatology, they remain highly uncertain. Previous work suggests that it may be possible to reduce this uncertainty by contextualizing forecasts within specific climate regimes. However, even with improved forecast skill, effective action hinges on the alignment of forecasts with the practical needs of conservation practitioners. Over the next decades, a co‐production approach will be critical for leveraging seasonal forecasts for climate change adaptation within the conservation sector. [ABSTRACT FROM AUTHOR]

The article cites studies that analyze the relation of orphanhood to the occurrence of human immunodeficiency virus (HIV)/AIDS in Africa. One paper draws upon an exceptional Tanzanian two-period data set. This data set may illuminate on the effects of orphanhood on human capital formation. Another issue refers to the cost of orphanhood to an economy over time, or the trade-off between allocating resources to mitigate the negative effects of orphanhood directly and investing in HIV/AIDS mitigation. It is found that HIV/AIDS can have a large negative impact on total factor productivity.
