Investigating the determinants of marine environmental degradation in Africa: What roles can economy, population, capture and energy play?

This study firstly examines the quality of marine eco-environment in Africa using Tapio decoupling model, and analyzes the sustainability level of the development of “population agglomeration - marine environment - economic growth”. Secondly, a series of econometric tools, such as ARDL, FMOLS, AMG model and DH panel causality test, are used to investigate the long- and short-term impacts of economic growth, population agglomeration, marine capture and energy consumption on the African marine eco-environment, and to analyze the differences between the sub-regions in Africa. The results indicate that: Adebayo and Kirikkaleli (2021) (Adebayo and Kirikkaleli, 2021) the decoupling state of “population-environment” has shifted from expansive negative decoupling to more optimized strong decoupling, and “economy-environment” has gradually changed from strong negative decoupling and expansive negative decoupling to strong decoupling. Ali et al. (2017) (Ali et al., 2017) There existed a bi-directional causal relationship between the degree of marine environment degradation and economic growth, population agglomeration, marine capture and energy consumption. Al-Mulali and Sab (2012) (Al-Mulali and Sab, 2012) In the short term, the economic EKC hypothesis does not hold in North and West Africa, while Central, East and Southern Africa are consistent with the EKC hypothesis. In the long term, the EKC hypothesis is valid in Central, East and Southern Africa, while is not valid in North and West Africa. Overall, reducing population agglomeration levels, marine fishing and energy consumption might mitigate marine environmental degradation in Africa.

Towards a healthier future for the achievement of SDGs: unveiling the effects of agricultural financing, energy poverty, human capital, and corruption on malnutrition

The objective of the present study is to address child and maternal malnutrition in nine African countries located in the Western sub-region of Sub-Saharan Africa (SSA) by incorporating three types of agricultural financing (domestic and external) along with energy poverty, human capital and corruption on malnutrition for the 1990–2019 period and present implications for Sustainable development goals (SDGs). This objective is realized by employing recently advanced panel techniques such as the second-generation panel econometrics techniques and the method of moments quantile regression (MMQR) approach. The estimated results reveal that agricultural credit and foreign aid in the agriculture sector significantly and negatively affect the malnutrition of children and mothers, while research spending in agriculture positively influences malnutrition. Energy poverty and human capital exert a negative and significant influence on child and maternal malnutrition, while corruption induces it. The study finally recommends several policy insights for the governments across the SSA region for tackling child and maternal malnutrition and advancing towards the achievement of SDG 3 through investment in SDG 4, SDG 7 and SDG 17.

Video-Based Directly Observed Therapy (ViDOT) as a strategic tool to improve medication adherence in epilepsy: A narrative review.

The prevalence of epilepsy is highest in the Central Africa subregion most especially in rural settlements. This is further compounded by a high prevalence of treatment gap, from poor drug adherence, and poor road network. One approach to overcoming this burden is to leverage Video-based Directly Observed Therapy (ViDOT) use for stable patients living with epilepsy, harnessing the advancement in mHealth technologies, and widespread adoption of smartphones. ViDOT is a form of telemedicine that is a smartphone-based, treatment approach for monitoring and evaluating remote patients. We performed a narrative review of the existing literature using electronic databases from PubMed and Google Scholar to identify relevant publications related to ViDOT and chronic diseases, in particular epilepsy. The selected articles were assessed for relevance, and key findings were synthesized to provide an overview of the role of ViDOT in addressing the challenges of drug adherence in epilepsy. The review shows that poor drug adherence is a major risk for poor outcomes in patients living with epilepsy. ViDOT has the potential to significantly contribute to improved drug adherence in patients living with epilepsy. Other benefits of ViDOT include the elimination of prolonged waiting times, improvement in access to specialized care, eradication of self-induced stigma and discrimination, diminishing neurologists' workload, and cost-effectiveness. Challenges include poor network coverage and unstable internet service. Giving a brief psychoeducation about epilepsy, anti-epileptic drug (AED) side effects, and the importance of sticking with the recommended drug use can improve AED adherence and epilepsy outcomes. Information dissemination through ViDOT to people with epilepsy and their caregivers at large is important to promote a healthy life.

Mental health of young talented football players in an African context: A cross-sectional observational study

BackgroundElite sport is a potentially pathogenic environment due to stressors like dual-career, high training demands, and performance pressure. Recent evidence suggests that athletes are at high risk of mental health issues. Even though the FIFA is increasingly paying attention, efforts directed towards young talented footballers are scarce. Few studies have even been conducted on young talented footballers in Africa. The majority of epidemiological studies on athletes also suffer from an analytical approach that does not highlight athletes' mental health profiles. This study aims to describe the mental health profile and their prevalence of young talented footballers in three African representative countries. MethodsThe study applied an observational-based cross-sectional research design with aspiring footballers from three sub-regions of Africa and aged between 10 and 23. The data was collected face-to-face from March to November 2022. Three screening tools were used to measure three mental health outcomes: Satisfaction With Life Scale (subjective well-being), Patient Health Questionnaire 9-item (depression), and Generalized Anxiety Disorder 7-item scale (anxiety). The mental health outcomes were rates and scores of well-being, depression, and anxiety, used in latent profile analysis. Findings507 male young talented footballers (263[51∙9%] Cameroonians, 73[14∙4%] Moroccans, and 171[33∙7%] Ivorians) were included in the analysis with a mean age of 15∙1 (SD 2∙37) years. Screening of mental health states revealed that 367(72∙3%) and 412(81∙8%) of these players experienced anxiety and depressive symptoms respectively and 155(30∙7%) experienced low well-being. Differences in mental health outcomes were noted between countries, age groups and competition levels. Three profiles of mental health condition were also identified, namely moderate mental health (Profile 1), languishing (Profile 2) and flourishing (Profile 3). InterpretationThe youth of football academies in the three African countries studied have a specific mental health profile, revealing a high prevalence of common mental disorders in the African context. These findings underline the need to enhance the awareness of mental health issues in young African players and provide tailored support. FundingFIFA.

Migratory movement of photo-identified humpback whales Megaptera novaeangliae along the southeastern coast of Africa

The global conservation of humpback whales Megaptera novaeangliae relies on continuous assessments of the populations’ post-whaling status, which in turn require information on population mixing and movements. One of the seven breeding stocks in the Southern Hemisphere, breeding stock C and its associated four substocks (C1–C4), utilises the western Indian Ocean in several discrete breeding grounds. However, information on the mixing of stocks across breeding grounds is limited. This study utilises photo-identification methods applied to the first multi-regional catalogue of fluke images available for substock C1S (the southern component of substock C1) which uses the southern portion of the breeding ground, developed as part of this study, to investigate the whales’ movements along the southeastern coast of southern Africa. The identification of 1 746 unique individuals, including 11 withinyear matches and 48 between-year matches of 45 individuals, provides new insight into the intra-regional migration patterns, fidelity and structure of substock C1S. The within-year match results confirmed that individual humpback whales are broadly seasonally present for extended periods and visit multiple subregions along this coast, while the between-year matches revealed long-term fidelity to this coastline. Moreover, five of the between-year matches between subregions in South Africa and Mozambique linked the South African migration corridor to the breeding ground in southern and central Mozambique. These findings provide valuable insights into the movement patterns of substock C1S and significantly address the challenges of effective population management, which includes difficulties associated with the whale-watching industry on the east coast of South Africa.

Institutional framework, macroeconomic instability and financial markets: perspective from emerging economies

Purpose The study evaluates the role of institutional framework and macroeconomic instability on financial market development among emerging economies.Design/methodology/approach The study uses panel data compiled from 32 countries from the sub-region of Sub-Sahara Africa (SSA), covering the period starting from 1996 to 2019. Empirical analyses were carried out using the two-step system generalized method of moments (TS-GMM) statistical framework.Findings Reviewed results suggest that institutional quality, effective governance and corruption control have a significant positive impact on financial market development among economies in the sub-region. Further empirical estimates show that macroeconomic risk and macroeconomic uncertainty have significant adverse effects on financial market development. Additionally, reported empirical estimates suggest that an improved institutional framework has the potential to lessen the adverse effect of macroeconomic instability on financial market development among economies in the sub-region.Originality/value The uniqueness of this empirical inquiry compared to related studies in the present literature stems from the fact that studies employing similar empirical approaches on the subject matter for economies in the sub-region are rare. Additionally, the analysis pursued in this study employs critical variables whose impact on financial market performance in the sub-region has not been examined per our review. These variables include indexes such as macroeconomic risk and institutional quality, which are unique to this study based on their construction; these indexes are generated using a principal component analysis procedure with different underlying variables compared to what may be found in the literature.

Reviewing Southern Africa’s Status as a Developmental Region through Governance and Development

This case study discusses how the democratic governance principles and norms impact development in the SADC, and how institutional and structural reforms require greater participation by society to address the governance challenges encountered in this subregion of Africa. Consequently, the aim of this paper is to examine and assess the relationship between SADC’s governance, democratic principles and norms, development plans and processes. A comparative analysis was conducted using SADC’s key democratic achievement connected to policies, processes, and remaining challenges. Subsequently, the key causes of SADC’s slow development on the African continent were explored, focusing on the failure to institutionalise liberal democratic governance consistently during postcolonial transition periods, speculating SADC’s slow development. The findings suggest that SADC is impacted by democratic principles, norms, and processes, such as local governance, civil society, and decentralisation of power. Bearing in mind Southern Africa’s economic frailty, elevated levels of civil unrest and poor service delivery, SADC authorities require a strong sub-regional governance strategy supported by robust national programmes to determine and overcome the factors hindering the institutionalisation of democratic principles in SADC, and promote strengthened institutional capacity. The unambiguous progression towards the consolidation of democracy, within the SADC, has impacted the governance and development successes of the region, resulting in democratic values and practices remaining shallowly rooted, and slow progress toward open and transparent governance.

Being My Neighbours’ Keeper: Interrogating the Management of the Terrorism–Migration Nexus in West Africa Sub-Region

Cooperation among neighbouring countries is critical for managing security threats like terrorism and migration. Despite their proximity, states often struggle to cooperate for various reasons, including a lack of solidarity, which can harm regional peace and stability. This study uses qualitative research to examine West African nations’ cooperation in combating Islamist terrorism and aiding affected individuals across borders. Applying regional security complex theory and transnationalism, we assess how terrorism-driven migration impacts regional security, peace and development, highlighting cooperation challenges. This study redefines ‘neighbour’ in international relations, emphasising proactive international solidarity and shared responsibility to address insecurity.

Psychosocial work factors affecting safety incidents of long-distance bus drivers in Ghana: Mediating role of psychological well-being

BackgroundImproving psychosocial work environment of long-distance bus drivers is essential for their psychological well-being and on-the-road safety. Despite the importance of the work environment of bus drivers, it has received little research attention in Ghana and other developing nations. Hence, this study examined the influence of psychosocial work factors (job demands and job resources) on safety incidents of long-distance bus drivers and how psychological well-being mediates this association. MethodsThis cross-sectional survey sampled 7315 long-distance bus drivers who commute from the cities of Accra and Tema to other parts of Ghana and other cities in the West Africa sub-region. Partial least squares structural equation modelling (PLS-SEM) was used to test four hypotheses. FindingsThe results suggest that job demands and job resources have direct association with safety incidents of the long-distance bus drivers. The psychological well-being of the bus drivers played a partial mediation role in the association between psychosocial work factors and safety incidents of the drivers. ConclusionThe job demand-resource model provides a useful model for understanding the impact of the work environment on driving performance among these long-distance bus drivers. Providing the drivers with high job control and supportive work culture can equip and support them to value the critical roles they play in the transport sector. Managers of bus transport companies and individual bus owners should implement effective communication strategies like the bottom-up communication approach, conduct periodic assessments to identify and address drivers’ precarious work conditions, create safety on the road, and reduce crashes and associated fatalities.

It offers something of a ‘framework within a framework’ by highlighting a series of issues and factors that must be unpacked to understand better the context of the Horn and the situations encountered therein, which we believe would aid leadership theorists and practitioners

Bias-corrected NASA data for aridity index estimation over tropical climates in Ghana, West Africa

Study regionGhana, West Africa. Study focusNASA's Prediction of Worldwide Energy Resource (NASA POWER) satellite-based reanalysis products are used for estimating the aridity index (AI) in Ghana, West Africa. The NASA estimates are compared and bias-corrected with temperature-based potential evapotranspiration estimates and rainfall data from 22 synoptic climate stations. The cumulative distribution function (CDF) matching technique was used for bias correction New Hydrological Insights for the regionThe results indicated a previous 36% over-estimation of arid conditions in dryland climates and an under-estimation of wetland climate regions by the NASA POWER data compared with the station-based estimation. Post bias-correction, the satellite-based estimates showed substantial improvements, as evidenced by a correlation coefficient of R2 = 0.87. The rectified data suggests that with accurate interpretations and calibrations, satellite-based metrics can play a pivotal role in advancing hydrological studies and water resource management in West Africa Sub-region. This insight underscores the potential of satellite data in augmenting regional hydrological research, establishing a foundation for similar studies in analogous global environments.

Spatiotemporal empirical analysis of particulate matter PM2.5 pollution and air quality index (AQI) trends in Africa using MERRA-2 reanalysis datasets (1980–2021)

In this study, the spatial-temporal trends of PM2.5 pollution were analyzed for subregions in Africa and the entire continent from 1980 to 2021. The distributions and trends of PM2.5 were derived from the monthly concentrations of the aerosol species from MERRA-2 reanalysis datasets comprising of sulphates (SO4), organic carbon (OC), black carbon (BC), Dust2.5 and Sea Salt (SS2.5). The resulting PM2.5 trends were compared with the climate factors, socio-economic indicators, and terrain characteristics. Using the Mann-Kendall (M-K) test, the continent and its subregions showed positive trends in PM2.5 concentrations, except for western and central Africa which exhibited marginal negative trends. The M-K trends also determined Dust2.5 as the dominant contributing aerosol factor responsible for the high PM2.5 concentrations in the northern, western and central regions of Africa, while SO4 and OC were respectively the most significant contributors to PM2.5 in the eastern and southern Africa regions. For the climate factors, the PM2.5 trends were determined to be positively correlated with the wind speed trends, while precipitation and temperature trends exhibited low and sometimes negative correlations with PM2.5. Socio-economically, highly populated, and bare/sparse vegetated areas showed higher PM2.5 concentrations, while vegetated areas tended to have lower PM2.5 concentrations. Topographically, low laying regions were observed to retain the deposited PM2.5 especially in the northern and western regions of Africa. The Air Quality Index (AQI) results showed that 94 % of the continent had an average PM2.5 of 12–35 μg/m3 hence classified as “Moderate” AQI, and the rest of the continent's PM2.5 levels was between 35 and 55 μg/m3 implying AQI classification of “Unhealthy for Sensitive People”. Northern and western Africa regions had the highest AQI, while southern Africa had the lowest AQI. The approach and findings in this study can be used to complement the evaluation and management of air quality in Africa.

Changes in the Seasonal Cycle of Heatwaves, Dry and Wet Spells over West Africa Using CORDEX Simulations

This study analyzes the potential response of the seasonal cycle of heatwaves (HWDI) and dry (CDD) and wet (CWD) spell indices over West Africa for the near- (2031–2060) and the far-future periods (2071–2100) under RCP4.5 and RCP8.5 scenarios using Coordinated Regional Climate Downscaling Experiment (CORDEX) simulations. Despite the fact that some relative biases (an underestimation of 30% for CDD, an overestimation of about 60% for CWD, and an overestimation of about 50% for HWDI) exist, during the historical period (1976–2005) in general, the CORDEX simulations and their ensemble mean outperform the seasonal variability in the above-mentioned indices over three defined subregions of West Africa (i.e., the Gulf of Guinea and Western and Eastern Sahel). They show high correlation coefficients (0.9 in general) and less RMSE. They project an increase (about 10 and 20 days) in heatwave days for both the near- and far-future periods over the whole West African region under both RCP scenarios. In addition, projections indicate that the Sahel regions will experience a decrease (about 5 days) in wet spell days from March to November, while in the Gulf of Guinea, a decrease (about 3 days) is projected throughout the year, except in the CCCLM simulation, which indicates an increase (about 5 days) during the retreat phase of the monsoon (October to December). Our results also highlight an increase (about 80%) in dry spells over the Sahel regions that are more pronounced during the March–November period, while over the Gulf of Guinea, an increase (about 40%) is projected over the entire year. Moreover, the months of increasing dry spells and decreasing wet spells coincide, suggesting that countries in these regions could be simultaneously exposed to dry seasons associated with a high risk of drought and heatwaves under future climate conditions.

First molecular detection of influenza D virus in cattle from commercial farm in Nigeria, Sub-Saharan Africa

Objective: To carrry out molecular surveillance of influenza D virus (IDV) in cattle in Lagos, Nigeria. Methods: Prospective epidemiological investigation was initiated in a large commercial farm market where animals in open pens were reared, sold, and butchered under poor hygienic conditions without adequate biosecurity measures. A total of 80 nasopharyngeal swabs were collected from cattle between October and November 2021. The samples were extracted using an RNA purification kit (NIMR). RNA extracts were amplified following a two-step PCR using FIREScript RT cDNA synthesis kit (Solis Biodyne, Estonia), followed by PCR OneTaq Quick-load 2X master-mix (NEB, UK) in a Rotor-Gene thermocycler (Qiagen, Germany). Amplicons were detected using a 1.5% Gel electrophoresis. Results: In total, 32.5% (26/80) IDV was detected in cattle. Sick animals showed higher burden of IDV with 65.4% (17/26) than 34.6% (9/26) in a healthy population, including 88.2% (15/17) cattle with diarrhoea and 11.8% (2/17) with nausea having IDV. An incidence of 69.2% (18/26) by sex was recorded in bull, which was more than twice compared to 30.7% (8/26) in cow. Age prevalence showed 62.2% (18/26), the highest detection in cattle of four years old, followed by 23.1% (6/26) in five years old, while the lowest 7.7% (2/26) was recorded in three years old. Conclusions: To the best of our knowledge, this study presents the first molecular detection of IDV in Nigeria and West Africa sub-region. It underscores the need for continuous surveillance of IDV at the animal-human interface.

Financial Institutions Dynamics, Investments and Development

The study evaluates how specific features of financial institutions and investment sources influence enduring development among economies in the sub-region of Sub-Saharan Africa (SSA). Data for the interactions in question were compiled from 36 economies in SSA from 1996 to 2019, and various empirical estimates were carried out using the two-step system Generalized Method of Moments statistical framework. Results from the analyses suggest that growth in depth, improved access, and efficiency of financial institutions foster long-term development among economies in the sub-region. Investments in various forms were found to have a varied augmenting impact on long-term development. Further empirical analyses suggest that quality of governance has a significant positive moderating impact on how net foreign direct investment and domestic investments influence development among economies in the sub-region. Political instability is, however, found to negate gains to development from both investment growth and contributions from financial institutions. JEL Codes: C33, G2, E13

Investigating the Impact of Education and Women in Agriculture on Human Capital Outcomes in Africa: An Interaction Analysis

Agriculture plays a crucial role in Africa's economy, and women constitute a significant proportion of the agricultural workforce in the region. Impact of women's role in farming and women education in Africa is significant for the human capital development. Furthermore, women's engagement in agricultural activities has increased with time, leading to improved contributions to food security and livelihood. Against this background, this study investigates the impact of women's participation in agriculture and women education interaction on human capital in Africa with the data obtained from the World Development Indicators (WDI) of the World Bank and Human Development Index (HDI) covering 33 African countries for the time frame 2000 to 2018. To control endogeneity that may be present in fixed effects model, the study applied the Generalised Method of Moments (GMM). The results show that, across African sub-regions, while women's participation in agriculture has a significant negative effect, education has a significant positive impact on human capital outcomes. Additionally, the interaction between women participation in agriculture and education has a significant positive impact on human capital across sub-regions in Africa. The findings underscore the need for policies that promote gender equality, as this has the potential to significantly increase human capital formation and sustainable development. The study, through the the interaction between women's in agriculture and education highlights the contribution of these factors to various goals, such as no poverty (SDG 1), zero hunger (SDG 2), quality education (SDG 4), gender equality (SDG 5) and decent work and economic growth (SDG 8).

The dynamics of Islamic marital jurisprudence in Islamic courts: the experience of the Kwara state and Zanzibar

Zanzibar is an island located in East Africa and part of the United Republic of Tanzania. In contrast, Kwara State is one of the states of the Federal Republic of Nigeria in the West Africa sub-region. Both regions have similar colonial histories and post-colonial experiences. Islamic Jurisprudence has undergone many reforms since the post-colonial era in Zanzibar Island of Tanzania and Kwara State of Nigeria. Islamic Jurisprudence is used in the adjudication process in Islamic religious courts in these two regions of Africa with a sizeable Muslim population. These courts essentially adjudicate Muslim personal matters, such as marriage, divorce, inheritance, wills, and endowment. The official jurisprudence of the people Zanzibar-Tanzania is Shafi’i jurisprudence. For the people of Kwara State of Nigeria, Maliki jurisprudence is recognized. Marriage is considered part of Muslim identity; therefore, applicable jurisprudence is necessary for a fair hearing on Muslim personal matters. The Muslim judges (qadis) play a laudable role in the justice system under Islamic Jurisprudence. This paper uses doctrinal, case law and empirical approaches for the discourse.
