    Economics and environmental-health risk assessment for sustainable development of the gold mining industry in Nigeria
    (University of Belgrade, Technical Faculty in Bor, Department of Engineering Management, 2024) Oyeranti, O.
    Though the gold mining industry potentially generates employment and increases Nigeria’s foreign exchange, the crude practices of artisanal miners often exacerbate environmental degradation and health hazards. Hence, humans face health risks when excessively exposed to the heavy metals released during gold mineralization. This study, therefore, adopts a descriptive approach towards suggesting a comprehensive economic evaluation and risk analysis for managing the impact of gold mining industry sustainably and bearing in mind people’s health that should equally be managed in a healthy and sustainable manner. A review of existing Environment-Health Risk Assessment (EHRA) studies on gold mining areas in Nigeria reveals that the estimated risk quotients are generally above recommended limits consequent upon inadequate enforcement of mining precautions. This study, therefore, argues that incorporating EHRA studies and considering economic costs and benefits of mining could provide an objective benchmark for managing various estimated health risk quotients and returns from more gold mining. For Nigeria’s, harnessing opportunities in the gold mining industry requires interdisciplinary drive that seeks to incorporate environmental-health risks into optimization of gold mining industry. Appropriate policy interventions will be expedient for gold mining industry to be less harmful and not constitute direct threat to sustainable development in Nigeria.

    Natural capital depletion and sustainable development: evidence from Nigeria
    (2023) Oyeranti, O. A.; Obijole, E. O.
    This study is an empirical investigation into the relationship between sustainable development and natural capital depletion in Nigeria. The study uses time series data from 1990 to 2020 on adjusted net saving, including particulate emission damage as a percentage of Gross National Income (GNI) using Adjusted Net Saving (ANS) as a proxy variable for sustainable development, while natural capital depletion is proxied using total natural resources rents as a percentage of GDP for capturing Natural capital (NC). The gross national income per capita (GNI) and the inflation rate (INF) are considered control variables in the study. Adopting the Autoregressive Distributed Lag (ARDL) model and the Bounds test approach to cointegration, the study finds a long-run relationship among the variables. While the main independent variable, NC positively relates to ANS, the relationship is found to be statistically insignificant. GNI is found to negatively impact ANS while INF showed a mixed relationship with ANS across the short and long run. The study concludes that Nigeria must look beyond depleting the stock of natural resources for the purpose of driving sustainable development.
