Introduction to International Waters and UNCLOS

The governance of international waters is primarily regulated by the United Nations Convention on the Law of the Sea (UNCLOS), 1982, which entered into force in 1994 and has been ratified by 168 parties as of 2024 (United Nations Treaty Collection). UNCLOS codifies maritime zones including territorial seas, contiguous zones, exclusive economic zones (EEZs), continental shelves, and the high seas, establishing a global legal framework balancing coastal state rights and freedoms of navigation. India enacted the Territorial Waters, Continental Shelf, Exclusive Economic Zone and Other Maritime Zones Act, 1976 to align with UNCLOS provisions, defining its maritime boundaries and jurisdiction. Despite UNCLOS’s comprehensive framework, enforcement challenges and jurisdictional ambiguities persist due to overlapping claims and limited institutional authority.

Key Legal Provisions Governing International Waters

UNCLOS divides maritime zones with specific legal regimes. Part II covers Territorial Sea and Contiguous Zone, granting coastal states sovereignty up to 12 nautical miles (nm) from baselines. Part V defines the EEZ extending 200 nm, where coastal states have sovereign rights for resource exploration and exploitation but not full sovereignty. Part VII governs the High Seas, defined in Section 121 as waters beyond national jurisdiction, where freedom of navigation, fishing, and scientific research prevail under international law.

• Territorial Sea (0–12 nm): Coastal state sovereignty including airspace and seabed; foreign vessels have right of innocent passage (UNCLOS Art. 17–27).
• Contiguous Zone (12–24 nm): Coastal state enforcement rights to prevent infringement of customs, fiscal, immigration laws (UNCLOS Art. 33).
• Exclusive Economic Zone (0–200 nm): Coastal state rights to natural resources, both living and non-living; freedom of navigation for other states (UNCLOS Art. 55–75).
• Continental Shelf: Coastal state rights to seabed resources up to 200 nm or beyond if geological shelf extends (UNCLOS Art. 76).
• High Seas: International waters beyond national jurisdiction; freedoms include navigation, overflight, fishing, and scientific research (UNCLOS Art. 87–115).

The International Tribunal for the Law of the Sea (ITLOS), established under UNCLOS, adjudicates disputes arising from interpretation or application of the Convention. Landmark cases include Philippines v. China (2016), where ITLOS arbitration invalidated China’s expansive South China Sea claims under the 'Nine-Dash Line'.

Economic Significance of International Waters and EEZs

The global maritime economy is valued at approximately $3 trillion annually (UNCTAD, 2022), with over 80% of global trade by volume transported via international waters (International Chamber of Shipping, 2023). Coastal states’ EEZs cover 38% of the world’s oceans, controlling resources worth $1.5 trillion (FAO, 2023). Illegal, unreported, and unregulated (IUU) fishing causes losses estimated at $23 billion annually (World Bank, 2021), undermining sustainable fisheries management.

• India’s EEZ spans 2.37 million sq km, ranking 18th globally (Ministry of Earth Sciences, 2023).
• India’s Blue Economy, including fisheries, offshore energy, and maritime transport, is projected to grow at 7-8% CAGR, reaching $100 billion by 2030 (NITI Aayog, 2023).
• Maritime zones provide critical resources: fisheries, hydrocarbons, minerals, and renewable energy potential.
• Illegal fishing and maritime crimes pose economic and security challenges for coastal states like India.

Institutional Framework for Enforcement and Dispute Resolution

UNCLOS establishes several institutions for governance and dispute resolution in international waters:

• International Maritime Organization (IMO): Regulates shipping safety, pollution control, and maritime security.
• International Tribunal for the Law of the Sea (ITLOS): Adjudicates disputes under UNCLOS, including delimitation and environmental issues.
• International Seabed Authority (ISA): Regulates mineral-related activities in the international seabed area beyond national jurisdiction; has issued 31 exploration contracts as of 2024 (ISA Annual Report).
• Food and Agriculture Organization (FAO): Monitors sustainable fisheries and combats IUU fishing globally.
• Indian Coast Guard (ICG): Enforces maritime laws within India’s jurisdiction, including EEZ and territorial waters.

Despite these frameworks, enforcement remains fragmented. UNCLOS lacks a centralized global maritime police force, limiting the ability to curb piracy, illegal fishing, and territorial encroachments unilaterally.

Challenges and Enforcement Gaps in International Waters Governance

UNCLOS’s legal framework is comprehensive but enforcement is weak due to:

• Absence of a global maritime enforcement agency to police high seas and EEZs.
• Overlapping maritime claims leading to jurisdictional disputes and conflicts.
• Limited capacity of coastal states to monitor and control illegal activities such as piracy, smuggling, and IUU fishing.
• Geopolitical rivalries undermining UNCLOS-based dispute resolution mechanisms.

India faces challenges in securing its vast EEZ against illegal fishing by foreign vessels and ensuring maritime security amid regional tensions.

Way Forward: Strengthening Governance of International Waters

• Enhance maritime domain awareness through satellite and coastal radar networks.
• Invest in capacity building of Indian Coast Guard and Navy for EEZ enforcement.
• Promote regional maritime cooperation frameworks for joint patrols and intelligence sharing.
• Advocate for strengthening UNCLOS enforcement mechanisms at the UN level.
• Leverage international dispute resolution mechanisms proactively to settle maritime boundary disputes.
