Exclusive economic zone of Chile

Exclusive economic zone of Chile Chile's exclusive economic zone spans a vast area of the southeastern Pacific and parts of the South Pacific and Southern Ocean adjacent to Chile’s continental margin and remote territories such as Easter Island and the Juan Fernández Islands. The zone underpins Chile’s activities linked to fisheries, marine geology, and maritime research while intersecting issues involving neighboring states including Peru, Argentina, Bolivia, and Ecuador. Key institutions, laws, and international instruments shape the EEZ’s governance and its role in regional geopolitics and natural-resource management.

Geography and Extent

Chile’s maritime zone extends from the continental coast of Antofagasta Region and Magallanes Region offshore to include waters around insular territories such as Rapa Nui (Easter Island), the Juan Fernández Islands, and the Desventuradas Islands. The resulting area overlaps marine biogeographic provinces like the Humboldt Current system, the Peruvian marine ecoregion, and subantarctic zones near the Drake Passage and the Scotia Sea. Chile’s seaward claims encompass continental shelf features, submarine plateaus, and abyssal plains abutting the Nazca Plate and the South American Plate, influencing hydrographic boundaries near the Chile Trench and the Peru–Chile Trench. The EEZ shapes access to maritime routes toward Valparaíso, Punta Arenas, and trans-Pacific corridors linking Asia via the Pacific Ocean.

Legal Framework and Delimitation

Chile’s maritime entitlements are grounded in domestic legislation such as the Ley de Marina Mercante and statutes administered by agencies like the Dirección General del Territorio Marítimo y de Marina Mercante (Directemar) and the Subsecretaría de Pesca y Acuicultura. Chile participates in international regimes including the United Nations Convention on the Law of the Sea, invoking provisions on exclusive economic zones, continental shelf rights, and maritime delimitation. Bilateral and multilateral instruments with Peru and Ecuador address boundary delimitation in the Southeastern Pacific, while agreements and adjudications involving Argentina have implicated continental shelf rights in the Beagle Channel and the South Atlantic. Chile has submitted scientific data to bodies such as the Commission on the Limits of the Continental Shelf to support extended continental-shelf claims.

Resources and Economic Activities

Chile’s EEZ supports major extractive and productive sectors including industrial anchoveta fisheries, pelagic and demersal fleets operating from ports like Iquique and Concepción, and aquaculture enterprises centered in Los Lagos Region. Harvests of species such as Engraulis ringens underpin exports to markets in China, Japan, and United States. The EEZ includes prospects for seabed minerals on the Nazca Plate margin and potential hydrocarbon reservoirs in basins explored by companies and state actors including ENAP and international energy firms. Marine biotechnology initiatives at institutions like the University of Chile and Universidad Austral de Chile pursue bioprospecting in kelp beds, while maritime transport through Valparaíso and Arica sustains trade linked to regional blocs such as the Pacific Alliance.

Management and Conservation

Chile manages its marine space through regulatory agencies including Sernapesca and conservation initiatives overseen by the Ministerio del Medio Ambiente and designated marine protected areas such as the Rapa Nui National Park maritime adjuncts and the Islas Desventuradas National Park. Scientific research by the Instituto de Fomento Pesquero and collaborative programs with international partners such as the Food and Agriculture Organization inform quotas, seasonal closures, and bycatch reduction measures. Conservation of habitats supporting species like the Humboldt penguin and migratory humpback whale is coordinated with frameworks like the Convention on Biological Diversity and regional accords addressing high-seas stewardship. Marine spatial planning incorporates inputs from fishing unions, aquaculture associations, and academic centers including Pontificia Universidad Católica de Chile.

Disputes and International Relations

Maritime delimitation has been a focal point in Chile’s relations with neighbors: the 2014 International Court of Justice judgment with Peru altered parts of the maritime boundary in the Southeastern Pacific, and longstanding diplomatic issues with Bolivia over access to the Pacific persist alongside historical treaties such as the Treaty of Ancón and debates tied to the War of the Pacific. Chile’s interactions with Argentina have involved continental shelf negotiations in the Beagle Channel and the Southern Ocean, while regional cooperation through forums like the South Pacific Regional Fisheries Management Organisation addresses illegal, unreported, and unregulated fishing with partners including Australia and New Zealand. Chile’s EEZ policies also interface with global governance structures such as the United Nations and regional trade agreements that influence resource management, security, and scientific collaboration.
