Artisanal Crude Oil Refining in the Niger Delta: EnvironmentalImpacts, Health Outcomes, and Strategies for Sustainable Mitigation

Abstract

Artisanal crude oil refining remains a significant environmental and health challenge in the Niger Delta. This review examines the long-term impacts of this unregulated practice, focusing on pollution pathways, community health outcomes, ecosystem degradation, and socioeconomic factors that sustain this illicit industry. We assess the extent of air, water, and soil contamination resulting from artisanal refining processes and identify the pollution pathways that contribute to elevated risks for respiratory illnesses, cancer, reproductive disorders, and other health issues within local populations. Additionally, we explore the degradation of local biodiversity and ecosystem health, illustrating the adverse effects on flora, fauna, and traditional livelihoods. Socioeconomic factors, including poverty and limited regulatory enforcement, exacerbate these health and environmental consequences. Finally, we review mitigation strategies and policy approaches aimed at reducing the adverse effects of artisanal refining while considering the socioeconomic realities of affected communities. This review provides comprehensive insights into the scale and complexity of the issue, highlighting the urgent need for holistic, community-driven solutions that address the environmental and health ramifications in the Niger Delta region.
