The concept of exclusive economic zones (EEZs) and sovereignty rights

An exclusive economic zone (EEZ) is a designated maritime area where a coastal nation holds sovereign rights over the economic resources of the sea, seabed, and subsoil. This zone extends up to 200 nautical miles from the coastline, with a nautical mile being equivalent to 1.852 kilometres. The term "sovereign" refers to having independent authority over a specific territory.

Key features of EEZs

• Extent of control - Covers a distance of up to 200 nautical miles from the coast, granting rights over both living and non-living resources.
• Sovereign authority - Coastal nations have the power to exploit, develop, manage, and conserve all resources within this area.
• International recognition - Established under international maritime law to define coastal state jurisdiction over adjacent waters.

The significance of EEZs in managing ocean resources

Exclusive economic zones play a crucial role in the stewardship of ocean resources, as they encompass a substantial portion of the world's marine wealth. By assigning control to coastal states, EEZs help regulate the use and conservation of these resources.

Importance of EEZs for resource management

• Oil reserves - Nearly 90% of known undersea oil reserves are located within EEZs.
• Fishing regions - Up to 98% of the world's primary fishing areas fall within these zones.
• Conservation responsibility - Coastal states are tasked with managing and conserving resources within their EEZs.

Competing territorial claims in the Arctic region

The Arctic region has become a focal point for territorial disputes due to the melting of sea ice, which has accelerated in recent years. This environmental change has unveiled access to valuable resources and potential trade routes.

Nations involved and their motivations

• Countries in contention - Five nations—Canada, Denmark, Norway, Russia, and the United States—are actively seeking to extend their territorial boundaries in the Arctic.
• Resource potential - The Arctic is estimated to hold up to a quarter of the world's undiscovered oil and gas reserves, including approximately 90 billion barrels of oil, with around 85% located offshore.
• Strategic trade routes - Melting ice is opening up routes like the North-West Passage, which could shorten shipping distances between major ports by thousands of kilometres.
• Fisheries expansion - Rising water temperatures have led to cod populations migrating as far north as 80°N, supported by abundant planktonic animals like copepods and krill.

Specific territorial disputes

• Russian claims - Russia asserts control over a large wedge of Arctic territory extending past the North Pole, including the Lomonosov Ridge.
• Disputed areas - Overlapping claims among the five nations create contested zones, with borders defined by various methods.
• Impact of ice melt - Predictions suggest that within a few decades, the Arctic could be largely ice-free during summer months, easing access for drilling and navigation.

Environmental and economic implications of Arctic resource exploration

The race to exploit Arctic resources brings both economic opportunities and significant environmental challenges.

Economic benefits of Arctic exploration

• Energy resources - Access to vast oil and gas reserves could meet global energy demands, especially as energy prices rise.
• Shipping advantages - New routes like the North-West Passage could reduce shipping times and costs.
• Fisheries growth - Increased marine life due to warming waters offers potential for expanded commercial fishing.

Environmental concerns and calls for protection

• Ecosystem vulnerability - The Arctic's fragile environment is at risk from drilling and shipping activities.
• Advocacy for treaties - Environmental groups propose a protective treaty akin to the Antarctic Treaty, which prohibits military activity and mineral mining.
• Climate change acceleration - Resource extraction and increased human activity could exacerbate global warming.

The complex interplay between economic gain and the need to preserve one of the planet's most sensitive regions.
