The extension of India’s sovereign maritime rights under UNCLOS in the Arabian Sea reflects the conceptual tension between economic resource sovereignty and maritime boundary conflicts. With an additional 10,000 sq. km claimed in the Central Arabian Sea, India continues to maneuver through legal, geopolitical, and scientific frameworks such as UNCLOS and the Commission on the Limits of the Continental Shelf (CLCS). This intervention presents both opportunities for resource exploration and risks of conflict in disputed waters.

UPSC Relevance Snapshot

  • GS-III: International maritime law (UNCLOS, EEZ, ECS), resource geopolitics, India’s energy security
  • GS-II: Bilateral and multilateral agreements, regional groupings affecting maritime boundaries
  • Geography (GS-I): Physical geography of oceans and continental shelf dynamics
  • Essay: Sovereign rights vs transnational cooperation in oceanic resource governance

Arguments FOR India’s Claim

The legal and scientific case for India's expanded claim rests on sovereign rights granted under UNCLOS, reinforced by the strategic necessity of resource access and national security safeguards. Verified data from India’s National Centre for Polar and Ocean Research (NCPOR) strengthens the scientific legitimacy of these claims.

  • UNCLOS Compliance: India follows Article 76 of UNCLOS, which allows claims beyond its 200 nautical mile EEZ, provided geophysical evidence proves the seabed is a natural extension of the landmass.
  • Resource Abundance: The extended shelf contains hydrocarbon and polymetallic nodules significant for India’s energy security and strategic resource autonomy. (Source: NCPOR, Economic Survey 2023)
  • Legal Modular Strategy: India’s phased approach through partial submissions (e.g., uncontested claims first) aligns with CLCS norms and minimizes direct conflict points.
  • Geostrategic Leverage: With growing competition in the Indian Ocean Region (IOR), India’s ECS claim consolidates its maritime dominance and counters China’s assertive activities.

Arguments AGAINST India’s Claim

The claim faces significant challenges, both geopolitical and procedural. Disputes with neighboring countries like Pakistan and Oman complicate the assertion of rights, while procedural scrutiny from CLCS on technical and legal aspects delays the claim's finalization.

  • Geopolitical Overlaps: Pakistan has objected to India’s submission, citing disputes near Sir Creek in the western Arabian Sea. Additionally, overlapping claims with Oman create shared resource issues despite a 2010 agreement.
  • Scientific Validity: CLCS rejected portions of India’s original ECS claim in March 2023, citing insufficient or ambiguous geological evidence.
  • Time-Intensive Processes: ECS claims take years to finalize due to the demanding technical data requirements, reviews, and bilateral negotiations over disputed waters.
  • Political Fallout: Unresolved disputes over ECS boundaries could strain diplomatic ties and impede India’s wider IOR strategy.

Comparative Analysis: India vs. Brazil in ECS Claims

Parameter India Brazil
Basis for Claim Scientific evidence of landmass extension in the Arabian Sea Geophysical evidence in the South Atlantic under the Brazilian Continental Shelf Project
Size of ECS Added 10,000 sq. km (current claim) ~900,000 sq. km
Geopolitical Overlaps Pakistan and Oman disputes No overlaps; uncontested submission
CLCS Review Partial acceptance; sections rejected in 2023 Broadly accepted; minor adjustments suggested by the CLCS
Strategic Relevance Energy security, resource nationalism, IOR dominance Exclusive oil drilling rights under Petrobras

What the Latest Evidence Shows

India’s claim leverages recent advancements in marine geological surveys, including bathymetric mapping and seismic data studies conducted by the NCPOR. While CLCS rejected the entirety of India’s original submission, the restructured partial submissions focus on uncontested areas, showing a strategic recalibration. As of 2024, this revised claim has gained preliminary acknowledgment from the CLCS, though bilateral negotiations with Pakistan remain unresolved.

Furthermore, India's ECS claims highlight its aspirations in the Indian Ocean Region, aligning with the vision of Project SAGAR (Security and Growth for All in the Region). However, Pakistan’s objections near Sir Creek expose vulnerabilities in India’s legal and geopolitical position.

Structured Assessment

  • Policy Design: Progressive alignment with UNCLOS standards; modular approach to claims shows adaptive policy design but lacks coordination mechanisms for multilateral dispute resolution.
  • Governance Capacity: Strong technical expertise via NCPOR and the Geological Survey of India; however, procedural delays in CLCS reviews and bilateral negotiations hinder timeliness.
  • Structural Factors: Overlapping claims, especially in sensitive regions like Sir Creek, pose bottlenecks, while the lack of robust multilateral arbitration frameworks hampers speedy resolutions.

250 Words15 Marks
What is the significance of India's claim over the continental shelf in the Arabian Sea?

India's claim over the continental shelf in the Arabian Sea is significant as it reflects its sovereign rights under UNCLOS, allowing enhanced access to vital maritime resources. Additionally, the claim aims to secure India's strategic position against geopolitical tensions, particularly in the context of China's assertiveness in the Indian Ocean Region.

What role does UNCLOS play in India's claim to the continental shelf?

UNCLOS, or the United Nations Convention on the Law of the Sea, underpins India's legal claim by providing a framework for maritime boundaries and resource rights. Specifically, Article 76 allows nations to extend claims beyond their 200 nautical mile exclusive economic zone, contingent on scientific evidence that supports the natural extension of landmasses.

What challenges does India face regarding its continental shelf claim in the Arabian Sea?

India's claim is challenged by geopolitical objections from neighboring countries such as Pakistan and Oman, complicating the assertion of rights. Additionally, the rejection of portions of India's ECS claim in March 2023 by the CLCS due to insufficient geological evidence further complicates the process.

How does the Commission on the Limits of the Continental Shelf (CLCS) impact India's submissions?

The CLCS impacts India's submissions by rigorously reviewing the geological and technical aspects of the claims presented. India's phased approach following CLCS norms seeks to minimize conflict, but procedural scrutiny can lead to lengthy delays, as seen in the rejection of past claims, thereby complicating timely resolution and resource access.

What strategic advantages does India seek from its continental shelf claim?

India aims to secure energy resources and strategic autonomy through its continental shelf claim, particularly in hydrocarbon and polymetallic nodules. This move not only addresses India's energy security concerns but also seeks to consolidate its maritime dominance in the Indian Ocean Region amidst growing regional competition.

A bare date like “18-February-2026” is not a defensible current-affairs topic unless it is anchored to a primary instrument such as a Gazette notification, regulator circular, court judgment, or a Bill/Act. The exam-relevant task is to convert the date into verifiable identifiers—issuing authority, legal basis (Act/Rules/Sections), instrument number, effective date, and thresholds—because UPSC frames MCQs around precisely these hard edges. The central thesis: the difference between narrative awareness and Prelims accuracy is source hierarchy discipline.
