Understanding Exclusive Economic Zones (EEZ) and Maritime Boundaries

What Are EEZs?

An Exclusive Economic Zone (EEZ) is a marine area extending up to 200 nautical miles from the baseline of a coastal state’s territorial sea. Within this zone, the state has sovereign rights for the purpose of exploring and exploiting, conserving, and managing natural resources of all types, whether living or non-living.

The concept was formalized by the United Nations Convention on the Law of the Sea (UNCLOS) in 1982, providing a legal framework for states to assert their rights over vast oceanic areas.

How Are EEZs Determined?

The determination of an EEZ is based on the natural prolongation of the land territory’s continental shelf. This means that a coastal state can claim an EEZ if its continental shelf extends beyond 200 nautical miles from its baseline, provided it does not exceed 350 nautical miles or more than 100 nautical miles beyond the outer edge of the continental margin.

In cases where maritime boundaries are disputed between two states, UNCLOS Article 15 provides for an equidistance line to be drawn as a median line. This method ensures that each state receives an equal share of the maritime area.

Why Is It Important?

The EEZ is crucial for states because it allows them to exploit resources such as fish, minerals, and energy from the seabed. This not only supports economic development but also ensures that coastal nations can manage their marine environment sustainably.

Moreover, the EEZ concept helps prevent conflicts over maritime boundaries by providing a clear legal framework for resource management and dispute resolution.

Real-World Examples

The United States, for instance, has an extensive EEZ that extends to the outer edge of its continental shelf. This zone is rich in natural resources, including oil, gas, and fish, which are managed by the state.

Another example is Norway’s EEZ, where it exercises control over vast areas of the North Sea and Norwegian Sea, allowing for significant offshore oil and gas production.
