Key Takeaways
- Pelican and Swan denote distinct geopolitical boundary frameworks used primarily in maritime delimitation and territorial administration contexts.
- Pelican boundaries emphasize natural coastal features and historical claims, often linked to colonial-era treaties and local topography.
- Swan boundaries prioritize equitable distribution of maritime zones based on continental shelf extensions and exclusive economic zones (EEZs).
- The application of Pelican and Swan frameworks influences bilateral negotiations, international law interpretations, and resource exploitation rights.
- Understanding their differences aids in resolving disputes over sovereignty, fishing rights, and offshore resource development in contested regions.
What is Pelican?

Pelican refers to a geopolitical boundary concept that focuses on defining territorial limits primarily through natural coastal markers and historical usage. It is often invoked in maritime boundary delimitation where traditional coastal geography plays a central role.
Rooted in Natural Coastal Features
Pelican boundaries rely heavily on the physical shape of coastlines, such as bays, headlands, and estuaries, to determine territorial extent. This approach respects the natural contours of shorelines, providing a geographically intuitive framework for boundary setting.
For example, the Pelican method might prioritize a prominent coastal promontory as a key reference point, regardless of whether it aligns with straight baseline rules. Such features often serve as the baseline from which territorial seas and other maritime zones are measured.
This method underscores the importance of local environmental characteristics, which can influence fishing zones and navigation rights. By grounding boundaries in physical landforms, the Pelican framework aligns well with coastal states’ interests in preserving traditional maritime access.
Historical Treaty Influence
Many Pelican boundaries derive from older treaties and agreements that predate modern international maritime law. These historical documents frequently use descriptive language tied to recognizable landmarks to define sovereignty.
As a result, Pelican boundaries often reflect colonial-era negotiations, embedding a legacy of historical claims into contemporary geopolitical maps. This can complicate modern disputes when historical descriptions conflict with current legal interpretations.
For example, several African coastal nations’ maritime boundaries are influenced by Pelican-style delineations inherited from European colonial powers. The persistence of these definitions sometimes leads to overlapping claims or ambiguous zones.
Localized Territorial Administration
Pelican boundaries are often favored in regions where local governance structures depend on clear, geographically grounded jurisdictional limits. This is particularly relevant in archipelagic states or areas with complex coastlines.
The clarity provided by natural landmarks helps local authorities manage resources, enforce laws, and regulate maritime traffic effectively. This practical utility makes Pelican boundaries a preferred choice for managing small-scale coastal and island territories.
Additionally, the Pelican method can integrate traditional fishing rights by recognizing customary marine tenure systems linked to specific coastal features. This integration supports community-based resource management within sovereign boundaries.
Application in Dispute Resolution
Pelican boundaries are often referenced in dispute resolution when negotiating maritime delimitation between neighboring states. Their reliance on natural markers can simplify complex claims by providing tangible, mutually recognizable points of reference.
However, challenges arise when physical features have changed due to erosion or sedimentation, leading to boundary ambiguities. In such cases, Pelican-based boundaries require supplementary legal interpretation or technological assessment to maintain clarity.
International courts and tribunals sometimes use Pelican principles to balance historical claims with current geographical realities, striving for equitable solutions. These rulings influence future bilateral or multilateral negotiations.
What is Swan?

Swan represents a geopolitical boundary principle focused on equitable maritime delimitation through continental shelf extension and exclusive economic zones. It is grounded in modern international law and emphasizes fairness in the distribution of oceanic areas.
Continental Shelf Extension as Core Criterion
Swan boundaries prioritize the natural prolongation of a state’s land territory beneath the sea, using geological and geomorphological data. This scientific approach ensures that coastal states receive maritime zones corresponding to their continental shelf’s extent.
By relying on continental shelf limits, Swan boundaries aim to prevent disproportionate claims by states with irregular coastlines or offshore islands. This method helps allocate seabed resources like oil, gas, and minerals more equitably.
The United Nations Convention on the Law of the Sea (UNCLOS) heavily influences Swan-based delimitation, providing a legal framework for continental shelf claims. Many coastal countries have submitted Swan-style claims to the Commission on the Limits of the Continental Shelf (CLCS).
Exclusive Economic Zone Distribution
Swan boundaries incorporate the concept of a 200-nautical-mile Exclusive Economic Zone (EEZ), where coastal states exercise special rights over marine resources. This framework balances sovereign rights with obligations to preserve shared marine environments.
The Swan approach often involves median line principles or negotiated adjustments to ensure equitable EEZ boundaries between adjacent or opposite states. This is especially important in semi-enclosed seas and narrow straits.
For example, in the South China Sea, Swan principles underpin some boundary proposals aiming to reconcile overlapping EEZ claims among multiple nations. Such frameworks promote peaceful coexistence and resource sharing.
International Law and Multilateral Cooperation
Swan boundaries reflect a modern, law-based approach to maritime delimitation, emphasizing compliance with international treaties and conventions. This ensures that boundary agreements align with globally accepted standards and dispute resolution mechanisms.
The multilateral nature of Swan-based delimitation encourages cooperative management of transboundary marine resources and environmental protection. This fosters stability in regions with complex maritime claims.
International tribunals frequently apply Swan principles when adjudicating disputes involving continental shelf rights and EEZ boundaries. These legal precedents influence future diplomatic negotiations and policy-making.
Resource Allocation and Economic Implications
The Swan framework plays a critical role in defining rights over offshore resources such as hydrocarbons, fisheries, and seabed minerals. By establishing clear boundaries, it helps prevent conflicts and encourages sustainable exploitation.
Coastal states benefit economically from Swan boundaries as they can confidently invest in resource extraction within their recognized zones. This security attracts foreign investment and supports national development strategies.
Moreover, Swan-based delimitation often includes provisions for joint development zones where resource sharing is necessary. These arrangements highlight the framework’s flexibility in accommodating complex geopolitical realities.
