Teressa Island Teressa Island is one of the Nicobar Islands in the Bay of Bengal, administered as part of the Andaman and Nicobar Islands Union territory of India. The island lies between Car Nicobar and Bompoka Island and has a mostly rural, indigenous population concentrated in coastal settlements. Teressa’s terrain includes low hills, tropical forests, and fringing coral reef systems that connect it ecologically to neighboring islands such as Bara and Camorta Island.

Geography

Teressa Island is located at the northern end of the Nicobar Islands chain in the Indian Ocean and is separated from Car Nicobar by a shallow channel near Nancowry Islands. The island’s area of approximately 101 km2 features volcanic-derived hills including Toma Peak and a coastline defined by sandy beaches, mangrove stands near Harpers Bay and fringing coral reefs that support reef fishes known from Andaman Islands faunal lists. Teressa lies within the Indo-Pacific biogeographic realm and experiences a tropical monsoon climate influenced by the Southwest Monsoon and Northeast Monsoon, with cyclone exposure linked to historical tracks through the Bay of Bengal. Marine corridors between Teressa and Katchal host migratory populations of green sea turtle, leatherback turtle, and species recorded in regional surveys alongside reef shark, groupers, and triggerfish.

History

Human settlement on Teressa Island is associated with the indigenous Nicobarese people and oral traditions that parallel colonization narratives in the Nicobar Islands; archaeological and ethnographic work has compared material culture with sites on Great Nicobar and Little Andaman. Contact with European explorers occurred during the era of Dutch East India Company and British East India Company expansion in the Indian Ocean; Teressa later came under the administrative reach of British India before incorporation into the modern Republic of India following independence in 1947. The island was affected by the seismic events of the 2004 Indian Ocean earthquake and tsunami, which altered coastal profiles across the Nicobar Islands and prompted humanitarian operations involving Indian Armed Forces, United Nations agencies, and international NGOs that operated in the Andaman and Nicobar Islands. Post-tsunami rehabilitation involved infrastructure projects coordinated with Ministry of Home Affairs (India) and regional development programs.

Demographics

Teressa’s population comprises indigenous Nicobarese people alongside migrants from mainland India and neighboring island groups; local languages include Nicobarese dialects and Hindi with influences from Tamil and Telugu. Census figures from 2011 recorded about 1,934 residents distributed among village settlements such as Kalasi, Carmia, and other hamlets; household livelihoods are typically based on subsistence agriculture, artisanal fishing, and small-scale trading with ports on Car Nicobar and Port Blair. Religious practice on the island includes Christianity and Hinduism as present across the population following historical missionary contacts related to London Missionary Society activities in the region. Demographic challenges noted in regional planning documents include remoteness from Mainland India and vulnerabilities to natural hazards like cyclones and tsunamis.

Economy and Infrastructure

Economic activity on Teressa focuses on smallholder agriculture, copra production linked to Cocos nucifera plantations common across the Nicobar Islands, artisanal fisheries supplying local markets, and limited reef-related tourism visited by specialized marine researchers from institutions such as Zoological Survey of India and international universities. Transport links include inter-island boat services connecting to Car Nicobar and occasional ship calls coordinated through administration at Panchavati and transit hubs such as Port Blair. Infrastructure development after the 2004 Indian Ocean earthquake and tsunami included reconstruction of housing, community buildings, and basic health posts supported by the Government of India and National Disaster Management Authority (India). Electrification, freshwater supply, and telecommunication services have been advanced incrementally with projects involving Ministry of Home Affairs (India) and regional engineering teams.

Flora and Fauna

Teressa’s ecosystems encompass lowland tropical forests, coastal mangroves, and coral reef assemblages that harbor species shared with adjacent islands like Little Nicobar and Great Nicobar. Forests hold tree species recorded in regional flora surveys, and birdlife includes species documented by ornithologists working in the Andaman and Nicobar Islands such as Nicobar pigeon relatives and migratory shorebirds that use intertidal flats. Marine biodiversity features corals, reef fishes, and marine turtles that are also subjects of conservation initiatives by organizations such as the Wildlife Institute of India and regional conservation NGOs. Invasive species and post-disaster habitat changes have been topics in ecological assessments by researchers from institutes including Indian Council of Agricultural Research and State Forest Department (Andaman and Nicobar).

Governance and Administration

Administratively, Teressa Island falls within the Nancowry (tehsil) of the Nicobar district under the Andaman and Nicobar Islands Union territory government; local governance includes village-level councils and coordination with district authorities for civil administration. Law enforcement and disaster response are managed through units of the Andaman and Nicobar Police and civil agencies including the National Disaster Response Force when required. Development planning, land use regulation, and conservation policy are overseen by agencies such as the Andaman and Nicobar Islands Integrated Development Corporation and the Ministry of Home Affairs (India), with input from community representatives and customary leaders among the indigenous population.
