The Andaman & Nicobar Islands is a union territory of India. Informally, the territory's name is often abbreviated to A & N Islands, or ANI. It is located in the Indian Ocean, in the southern reaches of the Bay of Bengal, near Myanmar and Indonesia. It comprises two island groups - the Andaman Islands and the Nicobar Islands - which separate the Andaman Sea to the east from the Indian Ocean. These two groups are separated by the 10° N parallel, the Andamans lying to the north of this latitude, and the Nicobars to the south. The capital of this territory is the Andamanese town of Port Blair.
The territory's population as per the most recent (2001) Census of India was 356,152. Added together, the total land area of the territory is approximately 6,496 km² or 2,508 sq mi.
In the Andaman Islands, the various Andamanese peoples maintained their separated existence through the vast majority of this time, diversifying into distinct linguistic, cultural and territorial groups. By the 1850s when they first came into sustained contact by outside groups, the indigenous peoples of the Andamans were:
In total, these peoples numbered somewhere around 7,000 at the time of these first encounters. As the numbers of settlers from the mainland increased (at first mostly prisoners and involuntary indentured labourers, later purposely recruited farmers), these indigenous peoples lost territory and numbers in the face of land encroachment and the effects of various epidemic diseases. The Jangil and most of the Great Andamanese groups soon became extinct; presently there remain only approximately 400-450 indigenous Andamanese, the Jarawa and Sentinelese in particular maintaining a steadfast independence and refusing most attempts at contact.
The indigenous peoples of the Nicobars (unrelated to the Andamanese) have a similarly isolated and lengthy association with the islands. There are two main groups:
The British used the islands as an isolated prison for members of the Indian independence movement. The mode of imprisonment was called Kalapani. The Cellular Jail in Port Blair was regarded as the "Siberia" of British India.
The islands were administered as a Chief Commissioner's Province.
The British continued their occupancy until the Japanese Invasion and Occupation of the Andaman Islands during World War II.
At the independence of both India (1947) and Burma (1948), the departing British announced their intention to resettle all Anglo-Indians and Anglo-Burmese on the islands to form their own nation, although this never materialized. It became an Indian union territory (UT) in 1950.
While newer settlers of the islands suffered the greatest casualties from the tsunami, most of the aboriginal people survived because oral traditions passed down from generations ago warned them to evacuate from large waves that follow large earthquakes.

There are 572 islands in the territory, of which only some 38 are permanently inhabited. Most of the islands (about 550) are in the Andamans group, 26 of which are inhabited. The smaller Nicobars comprise some 22 main islands (10 inhabited). The Andamans and Nicobars are separated by a channel (the Ten Degree Channel) some 150 km wide.
The total area of the Andaman Islands is some 6,408 km²; that of the Nicobar Islands approximately 1,841 km².
The South Andaman forests have a profuse growth of epiphytic vegetation, mostly ferns and orchids. The Middle Andamans harbours mostly moist deciduous forests. North Andamans is characterised by the wet evergreen type, with plenty of woody climbers. The north Nicobar Islands (including Car Nicobar and Battimalv) are marked by the complete absence of evergreen forests, while such forests form the dominant vegetation in the central and southern islands of the Nicobar group. Grasslands occur only in the Nicobars, and while deciduous forests are common in the Andamans, they are almost absent in the Nicobars. The present forest coverage is claimed to be 86.2% of the total land area.
This atypical forest coverage is made-up of twelve types namely:
Padauk being sturdier than teak is widely used for furniture making.
Burr and the Buttress formation in Andaman Padauk are world famous for their exceptionally unique charm and figuring. The largest piece of Buttress known from Andaman was a dining table of 13' x 7'. The largest piece of Burr was again a dining table to seat eight persons at a time.
The holy Rudraksha (Elaeocarps sphaericus) and aromatic Dhoop/Resin trees also occur here.
These islands are traditionally known for their shell wealth, especially in the genera Turbo, Trochus, Murex and Nautilus. Earliest recorded commercial exploitation began during 1929. Shells are important to these islands because some like turbo, trochus & nautilus etc. are used as novelties supporting many cottage industries producing a wide range of decorative items & ornaments. Shells such as giant clam, green mussel and oyster support edible shellfishery, a few like scallop, clam, and cockle are burnt in kilns to produce edible lime.
A total of 48,675 hectares of land is used for agriculture purposes. Paddy, the main food crop, is mostly cultivated in Andaman group of islands, whereas coconut and areca nut are the cash crops of Nicobar group of islands. Field crops, namely, pulses, oilseeds and vegetables are grown, followed by paddy during Rabi season. Different kinds of fruits such as mango, sapota, orange, banana, papaya, pineapple and root crops are grown on hilly land owned by farmers. Spices, viz., pepper, clove, nutmeg, and cinnamon are grown under multi-tier cropping system. Rubber, red oil, palm and cashew are grown on a limited scale in these islands.
There are 1,374 registered small scale, village and handicrafts units. Two units are export oriented in the line of fish processing activity. Apart from this, there are shell and wood based handicraft units. There are also four medium sized industrial units. SSI units are engaged in the production of polythene bags, PVC conduit pipes and fittings, paints and varnished, fibre glass and mini flour mills, soft drinks and beverages, etc. Small scale and handicraft units are also engaged in shell crafts, bakery products, rice milling, furniture making , etc. The Andaman and Nicobar Islands Integrated Development Corporation has spread its wings in the field of tourism, fisheries, industries and industrial financing and functions as authorised agents for Alliance Air/Jet Airways.
