Purpose: Interaction between environmental pollution and economic growth determines the achievement of the green growth objective of developing economies. An economy turns around the inverted U-shaped environmental Kuznets curve (EKC) when pollution is effectively dampened by social, political and economic factors as such economy grows. Thus, the purpose of this paper is to examine the EKC considering the impact of institutional quality on six variables of environmental pollution (carbon dioxide (CO₂), nitrous oxide (N₂O), suspended particulate matters (SPM), rainfall, temperature and total greenhouse emission (TGH)) using the case of Nigeria.Design/methodology/approach: The EKC model includes population density, education expenditure, foreign direct investment and gross domestic investment as control variables, and it was analysed using the autoregressive distribution lag (ARDL) econometric technique, which has not been applied in the literature on Nigeria.Findings: The results, inter alia, indicate that there is EKC for CO₂and SPM. This implies that the green growth objective can be pursued in Nigeria with concerted efforts. Other environmental pollution indicators did not exert significant influence on economic growth.Practical implications: Therefore, it is recommended that Nigeria’s institutional quality be strengthened to limit environmental pollution in light of economic growth.Originality/value: Previous studies are yet to apply a more developed econometric method, like the ARDL, to estimate the EKC model for Nigeria. This study fills this observed knowledge gap.

Background: The problem of poverty eradication has been limited to the Economic Community of West African States (ECOWAS) region, which accounts for more than 40% of the world's poor population. The majority of these people are rural farmers who depend solely on agriculture for livelihood. Agriculture in West Africa remains the largest means of employment in which more than 60% of the sub-region’s active labour force is involved. Objective: This study examined the potentials of agriculture to generate employment for the people, thereby reducing the level of poverty in West Africa. Methods: The Generalized Method of Moments (GMM) econometric technique was employed in this study for the panel data covering the period of 17 years (2000 to 2016). Results: Results from the study showed that agriculture provides the opportunity for the poor to increase their earnings to escape the poverty trap, whether the poor can seize these agricultural opportunities depends on their human capital development. Conclusion: The study, therefore, concluded that effective policies (e.g. social protection) should be formulated in the agricultural development plans that will prioritize sustainable land and water management, access to markets, and the food security. To achieve this, the use of modern methods should be encouraged through farm incentives to boost agricultural production and increase farmer’s income which is earned through the sale of agricultural commodities, and thus; in the long run, increase the revenue accruing to the government and reduce the rate of poverty.

To “end poverty in all its forms everywhere” and “reduce inequality within and among countries”, this study aligns with the 2030 Sustainable Development Goals 1 and 10. It uniquely contributes to the growth-poverty-inequality discourse by using per capita consumption expenditure growth (poverty), Gini index (inequality) and GDP growth (economic growth). It is a comparative analysis of 58 Sub-Saharan Africa (SSA) and Latin American (LAC) countries (from 2000 to 2015) to determine whether economic growth reduces the incidence of poverty and if its interaction with income inequality enhances or alters its impact on poverty. Consistent findings from a multi-analytical approach using pooled ordinary least squares, fixed effects and system GMM reveal that: (1) economic growth exhibit poverty-reduction properties; (2) the growth rate of inequality intensifies poverty, (3) inequality aggravates the impact of growth on poverty, and (4) the growth-poverty-inequality trilemma differs across income groups and regional samples. Furthermore, this study submits that the interaction of income inequality dampens the positive impact of economic growth on the incidence of poverty and supports the argument that the extent of inequality lessens the effect of inclusiveness. Hence, income inequality is a crucial determinant of poverty. Policy implications are discussed.

Background: Agricultural production is low in Nigeria as a result of low utilisation of farm inputs facilitated by farmers’ inability to save and invest. Therefore, credit is needed by farmers to enhance their productive capacity and efficiency in agriculture.Aim: Given the importance of credit to farmers, this study examined the nexus between households’ access to credit and agricultural production in Nigeria.Setting: The study made use of data from the Living Standard Measurement Study-Integrated Survey on Agriculture (LSMS-ISA) consisting of 4210 households across the 36 states in Nigeria, as well as the Federal Capital Territory, Abuja.Methods: The study employs the propensity score matching (PSM) technique.Results: The main result from the study suggests that households who had access to agricultural credit facilities had yields that are thrice those of their counterparts who did not benefit from such facilities. In the event of a shock, the farmers who did not have a source of credit are often forced to adopt measures such as lowering consumption and selling assets, which in the long run worsen their poverty levels.Conclusion: The study recommends that policymakers should address underlying factors that prevent access to credit for agricultural production, which is capable of raising the productive capacities of farmers.
