The role of environmental regulatory quality in the relationship between natural resources and environmental sustainability in sub-Saharan Africa

Natural resources benefit economies through economic growth and development. However, continuing unsustainable exploitation of these resources tend to harm the sustainability of the environment. Therefore, this paper explores the role of environmental regulatory quality (ERQ) in the relationship between natural resources (NR) and environmental sustainability (ES). The study covered 28 sub-Saharan African countries (SSA) from 2005-2017. Regarding the estimations, we utilized cross-sectional dependence, first-and second-generation unit root, and cointegration tests for preliminary checks. Finally, we used the system-GMM estimation for the analysis. We found that environmental regulatory quality improves environmental sustainability in SSA. We also observed that natural resources degrade environmental sustainability. Furthermore, we noticed that natural resources complemented environmental regulatory quality to reduce environmental sustainability in SSA. Therefore, we establish that ERQ in SSA does not complement NR to induce environmental sustainability. Based on the findings, we appeal for effective and rigorous implementation of environmental policies and regulations in SSA

Fermentation Capacity of Yeasts Using Mango (Mangifera indica Linn.) as Substrate

The goal of this study was to address the problem of large post harvest losses of mangoes by employing yeast fermentation technology to produce a more stable, value-added product in this case fruit wine. The design of the study involved determination of the fermentative capabilities of four commercial yeast types on musts obtained from an improved (Keitt) mango cultivar that is popularly cultivated in some parts of Ghana for export. The characteristics of the mango musts that were monitored included total soluble solids (TSS), pH and total acidity (TA), microbial populations (aerophilic mesophiles, yeasts and Acetic acid Bacteria), alcohol content and colour over the course of the fermentations. Descriptive and hedonic sensory evaluation was carried out on the ferments obtained from all treatments. Results showed that two of the yeast types namely; Red Star Pasteur and Red Star Montrachet displayed superior fermentation characteristics and produced mango wines that were acceptable by both descriptive and affective sensory panels. Keywords: mango, yeast, fermentation, alcohol, wine, must, soluble solids, acidity

The Prevalence and Risk Factors of Hepatitis B Virus Infection Among Dwellers in A Peri-Urban District of Ghana: A Cross-Sectional Study

Hepatitis B virus (HBV) infection is a significant health issue affecting about 296 million people worldwide. The disease is of great public health concern in Ghana as the country is within the endemic region of HBV infection. This study sought to determine the prevalence of HBV infection and associated risk factors among dwellers in a peri-urban district of Ghana. This cross-sectional descriptive study was conducted in the Sunyani West District of the Bono Region of Ghana. Respondents aged ≥18 years were purposively recruited from the four major towns in the District with health centres. A questionnaire was used to collect data from participants, and a rapid diagnostic test for the sero-presence or otherwise of hepatitis B infection was conducted. A total of 992 respondents took part in the study, with the prevalence of HBV infection using HBsAg as a marker among all the study participants being 2.9% (male 4.0% (12/298), female 2.5% (17/694)). Females aged between 20-29 years had a comparatively higher prevalence of hepatitis B infection than their corresponding males. The intake of alcohol (RR=4.23; 95% CI:2.05-8.74, p <0.000), previously diagnosed of having a sexually transmitted disease (RR= 2.43; 95% CI: 1.03-5.71, p = .04) and having multiple sexual partners (RR= 2.27; 95% CI: 1.11-4.65, p = .02) were the significant risk factors for HBV infection among the study participants. The study showed a low prevalence of HBV infection in the Sunyani West District of Ghana using HBsAg as a serum marker to diagnose the infection.

Psychological impact of COVID-19 on diabetes mellitus patients in Cape Coast, Ghana: a cross-sectional study

Introduction: COVID-19 pandemic has had a greater psychological impact on patients with chronic ailments such as diabetes mellitus, tuberculosis, and HIV/AIDS compared to those without chronic conditions. We explored the psychological impacts of COVID-19 among people living with diabetes mellitus in Ghana. Methods: this study employed a hospital-based cross-sectional design involving 157 diabetes mellitus patients aged 20 years and above. We assessed diabetes distress by the seventeen-item diabetes stress (DDS17) scale and COVID-19 worries by 3 specific benchmarks: “worry about overly affected due to diabetes if infected with COVID-19”, “worry about people with diabetes characterized as a risk group” and “worry about not able to manage diabetes if infected with COVID-19”. A close-ended questionnaire was used in data collection. Results: of 157 diabetic patients interviewed, the majority had type 2 diabetes mellitus with known complications and only 42.7% were managing COVID-19 symptoms. The participants showed moderate to high level of COVID-19 specific worry, moderate fear of isolation, and low level of diabetes-associated distress. About 33.8% of the study population expressed a sense of worry towards the pandemic. The logistic regression showed that age, employment status, and presence of other chronic diseases were significantly associated with worries about being overly affected if infected with COVID-19 due to their diabetes status. Age and sex were associated with worries about people with diabetes being characterized as a risk group and age, sex and employment status were associated with participants who were worried about not being able to manage diabetes if infected with COVID-19. Conclusion: the general trend indicates a sense of worry among diabetes patients during the COVID-19 pandemic which is associated with poorer psychological health. Clients' education and counseling on COVID-19 are necessary to address some of their concerns to minimize the level of anxiety and emotional stress in these individuals

Credit Information Sharing and Loan Default in Developing Countries: The Moderating Effect of Banking Market Concentration and National Governance Quality

Departing from the existing literature, which associates credit information sharing with improved access to credit in advanced economies, we examine whether credit information sharing can also reduce loan default rate for banks domiciled in developing countries. Using a large dataset covering 879 unique banks from 87 developing countries from every continent, over a nine-year period (i.e., over 6,300 observations), we uncover three new findings. First, we find that credit information sharing reduces loan default rate. Second, we show that the relationship between credit information sharing and loan default rate is conditional on banking market concentration. Third, our findings suggest that governance quality at the country level does not have a strong moderating role on the effect of credit information sharing on loan default rate

Social factors influencing child health in Ghana

Objectives Social factors have profound effects on health. Children are especially vulnerable to social influences, particularly in their early years. Adverse social exposures in childhood can lead to chronic disorders later in life. Here, we sought to identify and evaluate the impact of social factors on child health in Ghana. As Ghana is unlikely to achieve the Millennium Development Goals’ target of reducing child mortality by two-thirds between 1990 and 2015, we deemed it necessary to identify social determinants that might have contributed to the non-realisation of this goal. Methods ScienceDirect, PubMed, MEDLINE via EBSCO and Google Scholar were searched for published articles reporting on the influence of social factors on child health in Ghana. After screening the 98 articles identified, 34 of them that met our inclusion criteria were selected for qualitative review. Results Major social factors influencing child health in the country include maternal education, rural-urban disparities (place of residence), family income (wealth/poverty) and high dependency (multiparousity). These factors are associated with child mortality, nutritional status of children, completion of immunisation programmes, health-seeking behaviour and hygiene practices. Conclusions Several social factors influence child health outcomes in Ghana. Developing more effective responses to these social determinants would require sustainable efforts from all stakeholders including the Government, healthcare providers and families. We recommend the development of interventions that would support families through direct social support initiatives aimed at alleviating poverty and inequality, and indirect approaches targeted at eliminating the dependence of poor health outcomes on social factors. Importantly, the expansion of quality free education interventions to improve would-be-mother’s health knowledge is emphasised

Heavy metals concentration and distribution in soils and vegetation at Korle Lagoon area in Accra, Ghana

The call for reclamation of land around Korle Lagoon in Accra, Ghana, where burning of e-waste and cultivation of vegetables takes place, makes risk assessment of heavy metal contaminations important. This study aimed at evaluating the levels and risk of heavy metal contamination in soils and vegetation around the Korle lagoon area in Accra. Geoaccumulation index, enrichment factor and pollution load index were determined to assess the risk of contamination. The levels and distribution of nine heavy metals (Pb, Hg, Cd, As, Zn, Sn, Ni, Cu and Cr) in soil (0–20 cm) and common vegetation (Panicum maximum, Imperata cylindrica, Lactuca sativa and Hibiscus sabdariffa) from the area using Atomic Absorption Spectrometer (AAS) were assessed. The area was divided into five sites, namely; the e-waste site (S1), gardens area (S2), recreational area (S3), reclaimed area (S4) estuary (S5) and the control (S6) which was about 700 m away. Soil analysis showed that the concentration of Pb (184.44 mg/kg), Cd (103.66 mg/kg), Cu (202.99 mg/kg), Ni (72.00 mg/kg) and Sn (705.32 mg/kg) at S1 exceeded their WHO/FAO thresholds for agricultural soils. Concentrations of heavy metals in soils from the e-waste site were significantly different (p < 0.01) from the other sites. High accumulations of heavy metals were also observed in the plants samples collected from the study sites, with the concentrations of Cu, Pb, Ni and Cd exceeding their acceptable limits. Laws against open burning of e-waste should be enforced and animals should be restricted from grazing on the forage

Greening the future: Unveiling the link between industrial structure upgrading and pollution emission in sub-Saharan Africa

AbstractIndustrial structure upgrading (ISU) in sub-Saharan Africa (SSA) has been improving in recent years, making it essential to examine how such upgrading influences pollution emissions in SSA. However, studies concerning the environment in SSA have overlooked this important role. Consequently, achieving the Sustainable Development Goals becomes futile if such critical issues are not given due attention in policy discourse. In light of this, this study examined the effect of ISU on pollution emissions in 28 SSA countries using data from 1980 to 2020 and employed two key measures of ISU as contributions to the literature. Regarding the analysis, the fixed effects, random effects, and feasible generalized least squares estimators and the Dumitrescu and Hurlin (D-H) causality test were employed. The results show that ISU improves the sustainable environment by reducing pollution emissions in SSA by 0.03–0.04%. Furthermore, economic growth (EG) increases pollution emissions by 0.63–0.72%, but after reaching a threshold level of 0.10%, EG reduces pollution emissions by 0.03–0.04%. This confirms the EKC hypothesis in the selected SSAs. The D-H causality analysis also reveals a bidirectional relationship between ISU and pollution emissions. Based on these results, we conclude that upgrading the industrial structure in SSA is crucial for a clean and sustainable environment

Prevalence, risk factors and psychological consequences of workplace violence among health workers in the Greater Accra region, Ghana: a cross-sectional study

Abstract Background Globally, close to one-third of all workplace violence (WV) occurs in the health sector. Exposure to WV among healthcare professionals in Ghana has been widely speculated, but there is limited evidence on the problem. This study therefore investigated WV, its risk factors, and the psychological consequences experienced by health workers in Ghana. Methods An analytic cross-sectional study was conducted in the Greater Accra region from January 30 to May 31, 2023, involving selected health facilities. The participants for the study were selected using a simple random sampling technique based on probability proportional-to-size. The data analyses were performed using STATA 15 software. Logistic regression analyses were employed to identify the factors associated with WV, considering a significance level of p-value < 0.05. Results The study was conducted among 607 healthcare providers and support personnel across 10 public and private hospitals. The lifetime career, and one-year exposure to any form of WV was 414 (68.2%) [95% CI: (64.3-71.9%)] and 363 (59.8%) [95% CI: (55.8-63.7%)], respectively. Compared to other forms of WV, the majority of healthcare workers, 324 (53.4%) experienced verbal abuse within the past year, and a greater proportion, 85 (26.2%) became ‘super alert’ or vigilant and watchful following incidents of verbal abuse. Factors significantly linked to experiencing any form of WV in the previous 12 months were identified as follows: older age [AOR = 1.11 (1.06, 1.17)], working experience [AOR = 0.91 (0.86, 0.96)], having on-call responsibilities [AOR = 1.75 (1.17, 2.61)], and feeling adequately secure within health facility [AOR = 0.45 (0.26, 0.76)]. Conclusion There was high occurrence of WV, and verbal abuse was the most experienced form of WV. Age, work experience, on-call duties, and security within workplace were associated with exposure to WV. Facility-based interventions are urgently needed to curb the incidence of WV, especially verbal abuse
