A geological marvel hiding in the Bay of Bengal just got its first step toward global recognition. Union Culture and Tourism Minister Gajendra Singh Shekhawat announced on Tuesday, October 20, 2026, that the Karst-Mud-Volcano Complex of Baratang in the Andaman and Nicobar Islands has been included in UNESCO's Tentative List — a crucial gateway toward full World Heritage inscription.

What Makes Baratang a Geological Standout

Baratang Island, tucked within the union territory of the Andaman and Nicobar Islands, hosts a rare combination of karst limestone formations and active mud volcanoes — natural phenomena seldom found together in a single landscape. The karst terrain produces dramatic cave systems and sea-carved arches, while the mud volcanoes — among only a handful on Indian soil — periodically vent gas and sediment from deep geological faults beneath the Andaman Sea. Together, they form a complex that scientists and conservationists have long flagged as globally significant.

UNESCO's Tentative List is not a decoration. It is the formal prerequisite for any country that wishes to nominate a site for full World Heritage status — sites cannot be considered without first appearing on it. Getting on that list is, therefore, the essential first move in a process that can eventually bring international conservation resources and tourism visibility to a region.

Shekhawat's Acknowledgement of Shah's Role

Minister Shekhawat was pointed in crediting Union Home Minister Amit Shah for his role in advancing the recognition. The Andaman and Nicobar Islands are a centrally administered union territory that falls under the Ministry of Home Affairs, making Shah's department a key institutional player in any heritage nomination originating from the archipelago. Coordination between the Culture and Home Ministries for union territories — particularly those with ecological or strategic sensitivity — is standard practice, and Shekhawat's public acknowledgement signals that inter-ministerial alignment was essential to clearing this milestone.

India's Quiet Ambition to Broaden Its Heritage Map

India's pursuit of UNESCO recognition has evolved well beyond the iconic sites of the Gangetic plain and Rajasthan's fortress cities. Over the years, the country has steadily added lesser-known natural and cultural sites to its tentative list, widening the geography of heritage tourism and anchoring conservation efforts in remote regions that might otherwise fall outside the policy spotlight. Baratang's inclusion fits squarely into this pattern — and directly into the government's Incredible India branding framework, which links international recognition to inbound tourism growth.

For the Andaman and Nicobar Islands, a UNESCO nod — even at the tentative stage — can shift the kind of traveller the archipelago attracts, drawing in geo-tourism and scientific interest alongside the existing beach-and-diving circuit. That diversification matters enormously for local communities whose livelihoods depend on visitor flows.

The Road From Tentative to World Heritage

The next step is a formal nomination dossier submitted to UNESCO, followed by evaluation by the International Union for Conservation of Nature (IUCN) for natural sites. That process can take years, and success is never guaranteed. But the Tentative List inclusion is the signal that New Delhi is serious — and that Baratang's mud volcanoes and limestone karsts are now, officially, on the world's radar.
