Most countries, notably those that signed the Paris Climate Agreement, prioritize achieving the zero carbon or carbon neutrality aim. Unlike earlier studies, this one assesses the contribution of environmental policy, clean energy, green innovation, and renewable energy to the E7 economies’ achievement of carbon neutrality goals from 1990 to 2019. Findings emanating from the study show that the EKC hypothesis is valid in E7 countries. Implying that emissions in the E7 countries increased with the kick-off of development but declined later due to possible potent environmental regulatory policies put in place. Similarly, across all models, renewable energy (REN), green innovations (GINNO), environmental tax (ETAX), and technological innovations (TECH) were found to exert a negative and significant impact on carbon emissions in the E7 countries both in the short and long run. On the other hand, economic expansion (GDP) positively impacts environmental deterioration. Furthermore, the country-specific result shows that, on average, Brazil, India, China, Russia, Mexico, and Indonesia have significant environmental policies aiding carbon abatement. Except for Brazil, Mexico, and Indonesia, the income growth in the rest of the countries does not follow the EKC proposition. Furthermore, the causality result revealed a unidirectional causal relationship between GDP, REN, and GINNO to CO₂ emission. No causality was found between ETAX with CO₂, while a bi-directional causality exists between technology and CO₂ emissions. Based on the finding, policymakers in the E7 countries should move away from fossil fuels because future electricity output will not be sufficient to reduce emissions considerably. Environmental regulations, encouraging technological innovation, adopting green and sustainable technology, and clean energy sources, among other things, demand radical and broad changes.

Marine plastic pollution is a critical environmental challenge facing policymakers globally. To reduce marine plastic pollution by engaging the people, this study estimated the determinants of waste disposal approach by households, their willingness to participate in road gutters/drainage channels cleanup program and the number of man-days they are willing to contribute. The study used a total of 600 households drawn from 30 enumeration areas. A semi-structured questionnaire was employed in data collection. Means, percentages, multinomial logit model and Heckman selection model were employed in data analysis. The study found that most (67.42 percent) of the households in the coastal city of Lagos engage in illegal waste disposal. Some variables, household size, involvement in previous community cleanup activities, receipt of waste management information, payment of waste management fee, and having a dumpster in a locality, significantly reduce the likelihood of illegal waste disposal. The study also found that most (75.50 percent) of the households were willing to clean up road gutters/drainage channels; however, most (83.20 percent) were only willing to contribute one man-day (eight hours) in a week. Gender and previous participation in voluntary service significantly influenced both households’ willingness to participate and the number of the man-days they are willing to contribute. Women are more likely to participate and contribute man-days to the activity. Education, household size and amount paid as waste management fee significantly reduced the number of man-days households are willing to contribute. In contrast, the provision of information on waste management significantly increased the number of days they are likely to participate. The study recommended providing waste management information and dumpsters to reduce illegal waste disposal, mobilizing citizens, especially women, the less educated and low waste fee-paying households, through well-packaged information about plastic pollution.

Purpose: The purpose of this paper is to develop and apply a distributional impact assessment methodology to empirically analyze distributional impact of public expenditure on human development using data from 20 states in Nigeria. For robustness of the analysis, expenditure on education, health, agriculture, rural development, energy, housing, environmental protection and portable water resources are employed as predictors of human development. The result reveals that expenditure on education, health, agriculture, rural development and water resources has positive marginal impact on human development. In contrast, the marginal impact of energy, housing and environmental protection is negative. Among the sectors, education, health, agriculture, rural development and water resources expenditure has positive marginal impact while energy, housing and environmental protection have decreasing marginal impact on human development. Design/methodology/approach: Panel approach. Findings: The result reveals that expenditure on education, health, agriculture, rural development and water resources has positive marginal impact on human development. Originality/value: A panel approach is used to investigate whether expenditure on education, health, agriculture, rural development and water resources has positive marginal impact on human development.

To attain sustainable development goals, reduction in child mortality is necessary. However, a major challenge exists in the procurement of healthcare services by individuals which is determined to a large extent by their level of income. Adopting random effect and fixed effect methodology and using survey data from Multiple Indicator Cluster Survey (2012) and General Household Survey (2012), this study examines the relationship between household income and child mortality. For the analysis, infant mortality rate, under-five mortality rate and neonatal mortality rate was modeled against household income and controlled for access to anti-natal care, access to safe water and sanitation, neonatal mortality rate, maternal education and household size in Nigeria. Results obtained show that household income has significant effect on neonatal mortality rate in Nigeria but household income has insignificant effect on infant and under-five mortality rates in Nigeria. Results also show that household size has significant effect on infant mortality rate and neonatal mortality rate in Nigeria. The study equally found that access to anti-natal care has significant effect on under-five mortality rate in Nigeria.

Determinants of fertility rate among women in Ghana and Nigeria: Implications for population growth and sustainable development

This article reviews the changing political undercurrent in health service delivery in Sub-Saharan Africa, chronicling the ideological shift in orientation toward neoliberalism in the health sector, an ideology crafted and introduced into Sub-Saharan Africa by the International Monetary Fund and the World Bank. The article examines the implication of this neoliberal reform on the efficiency in health care provision and on the quality and accessibility of health services by the poor and vulnerable. Drawing inference from countries like Nigeria, the authors argue that the ascendency of neoliberalism in the health systems of Sub-Saharan Africa has engendered unethical practices and introduced elements of moral hazard in the health sector, reducing the incentive for governments to develop effective service delivery over the long term. The authors therefore advocate for a rejection of neoliberal ideology in favor of a universal coverage principle if an inclusive health system is to be developed.
