Evaluate India's role as a regional public goods provider through INCOIS's tsunami early warning services in the Indian Ocean Rim.

A regional public good is a non-excludable service one state supplies for an entire neighbourhood. Since the 2004 tsunami, India's Indian Tsunami Early Warning Centre at INCOIS has supplied precisely this — tsunami advisories to 28 Indian Ocean Rim nations [1] — making it a genuine, if hazard-narrow, provider.

Strengths as a regional provider

• Institutional legitimacy: INCOIS is a designated Tsunami Service Provider under UNESCO-IOC's Indian Ocean Tsunami Warning and Mitigation System (IOTWMS) [2], so its bulletins carry multilateral sanction rather than unilateral assertion.
• Technical credibility: a densifying seismic backbone — National Center for Seismology observatories up from 86 (2014) to 174, with nationwide detection at Magnitude 3.0 [1] — underpins warnings the region cannot self-generate.
• Capacity building: UNESCO-IOC recognised INCOIS for excellence in ocean-hazard warning [3]; 26 coastal villages in Odisha hold Tsunami Ready certification [1][3], a community-preparedness template exportable across the Rim.
• Last-mile reach: dissemination via Sachet and the SAMUDRA app [1] extends the good to end-users, not just governments.
• Strategic dividend: first-responder credibility reinforces India's SAGAR outlook at low cost.

Limitations

• Warning is not preparedness: India controls detection, not recipients' evacuation capacity; benefits stall where national response systems are weak.
• Hazard-narrow: cyclones, storm surge and sea-level rise strike the Rim far oftener, yet India's larger investment — Mission Mausam, ₹2,000 crore across nine verticals [4] — is domestically oriented.
• Asymmetric burden: the service rests wholly on Indian budgetary lines, with no regional cost-sharing, raising sustainability questions.
• Coordination costs: multiple TSPs operate within IOTWMS [2], requiring careful de-confliction of bulletins.

On balance, India is a net contributor of regional public goods — technically credible, multilaterally anchored and freely offered. Deepening it means widening from tsunami alerts to integrated multi-hazard ocean services, institutionalising regional training under IOTWMS, and aligning with the Sendai Framework and the UN's "Early Warnings for All" goal. Sustained thus, INCOIS converts scientific capability into durable regional trust.
