Deep-Sea Mining in the Clarion-Clipperton Zone: Nauru's Post-Colonial Quest for Economic Recovery and the Challenges of International Governance

This paper examines the complex intersection of deep-sea mining, post-colonial resource exploitation, and international governance through the lens of Nauru's contemporary engagement with polymetallic nodule extraction in the Clarion-Clipperton Zone (CCZ). Drawing on recent developments in international seabed law and Nauru's historical experience with the ecological devastation caused by phosphate mining, this study analyzes how small island developing states navigate sponsorship agreements with multinational corporations under the International Seabed Authority (ISA) framework. The research explores critical questions of “effective control,” environmental protection, benefit-sharing mechanisms, and the tensions between national sovereignty and the principle of the common heritage of humankind. With the 2025 U.S. Executive Order challenging established international frameworks, this paper argues that current deep-sea mining governance structures risk replicating historical patterns of colonial exploitation while failing to adequately safeguard fragile deep-ocean ecosystems. The findings highlight an urgent need for strengthened regulatory frameworks that prioritize environmental precaution, equitable benefit distribution, and genuine capacity-building for developing nations, ensuring that the exploitation of the deep seabed does not repeat the injustices of terrestrial resource extraction.
