Question

What is an exclusive economic zone (EEZ)? Why are EEZs important to the economies of Pacific Island nations?

Answer 1

An exclusive economic zone (EEZ) is a maritime area established by the United Nations Convention on the Law of the Sea (UNCLOS) in which a coastal state has special rights. It extends up to 200 nautical miles (about 370 km) from the state’s baselines. Within its EEZ the coastal state has sovereign rights for the purpose of exploring, exploiting, conserving and managing natural resources of the waters, seabed and subsoil (living resources like fish and non‑living resources like oil, gas and minerals), plus jurisdiction over marine scientific research, the construction of artificial islands and protection of the marine environment. The EEZ is not full territorial sovereignty: other states retain navigation and overflight rights and certain freedoms.

Why EEZs matter to Pacific Island economies

- Huge ocean area relative to land: Pacific island states often have very large EEZs compared with their tiny land areas, giving them control over vast marine resources.
- Fisheries and food security: Tuna and other high-value stocks found in Pacific EEZs are a primary source of food, jobs (local fishing, processing) and export earnings.
- License and access fees: Many island governments generate substantial government revenue by selling fishing access or issuing licenses to distant‑water fleets and through regional arrangements (e.g., selling “fishing days”).
- Aquaculture and domestic industry: EEZ resources support local fisheries development, processing, and opportunities for value‑added exports.
- Offshore minerals and hydrocarbons: Seabed minerals (e.g., nodules) and potential oil and gas reserves represent future revenue streams.
- Tourism and ecosystem services: Healthy marine ecosystems (coral reefs, tuna abundance, clear waters) underpin tourism, coastal protection and cultural livelihoods.
- Sovereign management and conservation: EEZ control allows states to set conservation measures, combat illegal, unreported and unregulated (IUU) fishing, and manage stocks sustainably for long‑term economic benefit.

Constraints and challenges
- Monitoring and enforcement are costly and technically difficult across huge ocean areas; many Pacific states rely on regional cooperation and donor support.
- Resource dependence and external fishing pressure create vulnerability to price swings, stock depletion and political negotiation with distant‑water fishing nations.
- Climate change and sea‑level rise threaten marine ecosystems and the long‑term value of EEZ resources.

In short, EEZs give Pacific island nations legal rights over vast ocean resources, which are central to their revenues, food security, jobs, and cultural and environmental well‑being — but realizing that value requires effective management, enforcement and regional cooperation.
