The Role of International Law in Regulating Oil Pollution in the Niger Delta: An Assessment

This research assesses the role of international law in regulating oil pollution in the Niger Delta region of Nigeria, focusing on the South South geopolitical zone. The Niger Delta hosts one of Africa's largest concentrations of hydrocarbon extraction activities, and decades of oil spills have caused severe environmental degradation affecting communities across Rivers, Bayelsa, and Delta States. Drawing on the United Nations Convention on the Law of the Sea (UNCLOS), the International Convention for the Prevention of Pollution from Ships (MARPOL), and the Rio Declaration on Environment and Development, this study examines the international legal obligations binding on Nigeria and multinational oil corporations operating in the region. A descriptive and library-based methodology is employed, using environmental impact reports, judicial decisions, and recent scholarship on environmental governance in resource-rich developing states. The paper critically evaluates the enforcement mechanisms available under both international and domestic law, noting the limited effectiveness of Nigeria's National Oil Spill Detection and Response Agency. It also examines landmark cases involving Shell Petroleum Development Company and their implications for corporate accountability under international law. The study recommends the adoption of a binding international instrument on business and human rights, stronger domestic enforcement of environmental standards, and greater community participation in environmental governance in the Niger Delta. Keywords: oil pollution, Niger Delta, UNCLOS, MARPOL, environmental governance.
