Quick Revision: Underwater Cultural Heritage (UCH) in India is preserved and studied by the ASI’s Underwater Archaeology Wing, guided by the UNESCO Convention 2001, with key sites including Dwarka, Mahabalipuram, and Poompuhar.

Why is this in the news?

The Press Information Bureau (PIB) of the Ministry of Culture, Government of India, released a detailed statement on 30 July 2026, outlining India’s expanding initiatives in underwater cultural heritage (UCH) archaeology. The announcement highlighted the active research and exploration activities being conducted by the Underwater Archaeology Wing of the Archaeological Survey of India (ASI) at key maritime sites, including Dwarka, Bet Dwarka, Mahabalipuram, and Karaikal. Additionally, the government has granted licenses to the Tamil Nadu State Department of Archaeology for Poompuhar and to the National Institute of Oceanography (NIO) for exploratory dives at Bet Dwarka and nearby islands in Gujarat. This development underscores India’s growing commitment to documenting, preserving, and studying submerged cultural resources, aligning with global frameworks such as the UNESCO Convention on Underwater Cultural Heritage (2001).

Background

• The concept of underwater cultural heritage encompasses all traces of human existence with cultural, historical, or archaeological significance that have been partially or totally submerged in bodies of water, including oceans, seas, lakes, and rivers.
• India’s engagement with underwater archaeology gained formal recognition with the establishment of the Underwater Archaeology Wing within the Archaeological Survey of India (ASI) in the early 21st century, following international conventions and domestic policy shifts.
• The UNESCO Convention on Underwater Cultural Heritage (2001) provides a global legal framework for the protection and management of submerged cultural resources, to which India is a signatory.
• Maritime archaeology in India has historical roots in the exploration of ancient ports such as Poompuhar (Tamil Nadu), associated with the Sangam period, and Dwarka (Gujarat), linked to the mythological city of Lord Krishna.
• The ASI’s Underwater Archaeology Wing conducts systematic surveys, excavations, and conservation efforts at identified sites, often in collaboration with national and international institutions such as the National Institute of Oceanography (NIO).
• Budget allocations for underwater archaeology reflect the government’s prioritization of this domain, with dedicated funds for training, equipment, and field operations.

What is Underwater Cultural Heritage and India’s Role in Its Preservation?

• Underwater Cultural Heritage (UCH) refers to all remains of human existence—such as shipwrecks, submerged cities, port structures, and artifacts—lying underwater, which hold archaeological, historical, or cultural value.
• India’s Underwater Archaeology Wing, under the ASI, is the nodal agency responsible for the identification, documentation, excavation, and conservation of submerged cultural resources across the country’s vast coastline and inland water bodies.
• The ASI’s initiatives are guided by the UNESCO Convention on Underwater Cultural Heritage (2001), which emphasizes in-situ preservation, non-intrusive survey methods, and capacity-building for local archaeologists and marine scientists.
• Key sites under active investigation include Dwarka and Bet Dwarka in Gujarat, known for their mythological and historical significance as ancient port cities; Mahabalipuram in Tamil Nadu, famed for its rock-cut temples and maritime trade links; and Karaikal in Puducherry, a historical port city with Sangam-era connections.
• The National Institute of Oceanography (NIO) and the Tamil Nadu State Department of Archaeology are collaborating agencies, conducting specialized underwater excavations and surveys with technical and financial support from the central government.
• Training programs initiated by the ASI aim to build a cadre of Indian underwater archaeologists, equipping them with skills in sonar mapping, underwater photography, and artifact conservation techniques.
• The identification of additional sites like Vijaydurg and Janjira in Maharashtra for exploration by 2030 expands the geographical scope of India’s underwater heritage mapping, highlighting the diversity of submerged cultural landscapes.

Why it Matters

Cultural Heritage Preservation

• Systematic documentation of India’s submerged cultural assets, including potential ancient ports, shipwrecks, and submerged settlements.
• Integration of maritime archaeology with terrestrial heritage studies to reconstruct historical trade and cultural exchanges.
• Protection of intangible cultural heritage linked to coastal communities and traditional maritime practices.

Scientific Research & Innovation

• Advancement of underwater archaeology techniques, including non-invasive survey methods and 3D modelling of submerged sites.
• Collaboration between ASI, state departments, and oceanographic institutes fosters interdisciplinary research.
• Potential discovery of artefacts from the Indus Valley Civilisation, Mauryan, or Chola periods, enriching historical narratives.

Policy & Institutional Framework

• Strengthening of India’s compliance with UNESCO’s 2001 Convention on the Protection of the Underwater Cultural Heritage.
• Establishment of a legal and administrative framework for underwater heritage management, including licensing and funding mechanisms.
• Alignment with the National Mission on Monuments and Antiquities (NMMA) for holistic heritage conservation.

Strategic & Diplomatic Implications

• Enhancement of India’s maritime heritage diplomacy, particularly in the Indian Ocean region where submerged sites hold shared historical narratives.
• Support for India’s Blue Economy initiatives by integrating heritage conservation with sustainable ocean resource management.
• Potential to attract international collaborations in underwater archaeology, including with UNESCO and foreign research institutions.

Challenges

1. Technological Limitations
