Environmental and socio-economic impacts of illegal oil mining in the Niger Delta, Nigeria

Despite Nigeria’s vast oil wealth, sustainable development outcomes remain constrained by weak governance, environmental degradation, and persistent socio-economic inequality, particularly in the Niger Delta. This study examines the environmental and socio-economic impacts of illegal oil mining in Ifie-Kporo, Warri South, Delta State, Nigeria, focusing on how illegal oil mining, pipeline vandalism, and artisanal refining affect sustainable resource utilization. Anchored in political ecology and environmental justice, the research interrogates how power asymmetries and regulatory failures reinforce ecological damage and social vulnerability. A mixed-methods approach was adopted, combining 100 structured questionnaires, ten (10) key informants were purposively determined for interviews, including community leaders, farmers, and environmental stakeholders, and laboratory analysis of physiochemical and bacteriological water samples from the Ifie-Okporo River. Findings indicate that while pH, TSS, TS, TDS, zinc, nitrate, total hardness, chloride, sulfate, and sodium remained within permissible limits, turbidity, phosphorus, fluoride, lead, and BOD exceeded WHO standards. E. coli and total coliform counts were far above the recommended levels. The findings reveal substantial ecological contamination and public health risks, indicating the urgent need for stronger regulatory enforcement, institutional reform, and inclusive justice-centred environmental governance in oil-producing communities.
