Andaman & Nicobar Islands

State overview

The Andaman & Nicobar Islands UT spans 572 islands across roughly 700 km of the Bay of Bengal — only ~38 are inhabited. The 2004 Indian Ocean Tsunami devastated cultivation in Nicobar and southern Andaman, with land subsidence and salinity persisting two decades later. About 85% of A&N is forest reserve, severely restricting agricultural expansion. The UT's ~4 lakh population is heavily urban (Port Blair) and tribal — including the contact-protected Sentinelese of North Sentinel Island, the Onge of Little Andaman, the Jarawa of South-Middle Andaman, and the Shompen of Great Nicobar.

Agriculture is small-scale and mostly coconut-areca-plantation-based, with paddy and pulses on settler-managed plots. The UT is a minor contributor to the Coconut Development Board's national programme. Marine fisheries — tuna, prawn, lobster — drive the broader food economy. Cultivation is severely water-limited despite 3000 mm annual rainfall, because the lateritic island soils drain rapidly and there is no large surface storage.

Soil profile

A&N soils are lateritic, red-yellow and coastal alluvial, with mangrove-fringed soils on island peripheries. Many islands carry forest soils with deep organic horizons under tropical evergreen and semi-evergreen forest. Tsunami-affected soils along the December 2004 inundation belt remain salt-affected and partially restored. About 85% of A&N is forest reserve, dramatically limiting cultivation.

Water resources

Rainfall 3000 mm — high but concentrated in SW monsoon. Cultivation depends almost entirely on rainwater harvesting and small streams; only ~8% of cultivated land is irrigated. Drinking-water supply often relies on desalination in dry months.

Cropping calendar

A&N calendar: Paddy transplanted July, harvested December (single rainfed kharif crop). Coconut continuous year-round harvest. Areca nut harvest September-March. Cashew February-April. Pineapple harvest June-August.

MSP procurement & mandi network

No significant cereal MSP procurement at scale. Coconut Development Board procures copra. Marine fishery is supported by Marine Products Export Development Authority (MPEDA).

District-wise crop concentrations

3 districts: South Andaman (Port Blair area — most agriculture), North & Middle Andaman, Nicobar (deeply affected by 2004 tsunami; tribal-reserved areas of Jarawa, Onge, Sentinelese, Shompen restrict cultivation expansion).

Climate-resilience & soil-test interpretation

A&N is climate-vulnerable — sea-level rise, intensifying cyclones (Bay of Bengal), and persistent salinity from 2004 tsunami subsidence affect coastal cultivation. Note: A&N cultivation footprint is small — guide kept at 600-800 words.

Local language

Hindi and English are official. The UT has speakers of Bengali, Tamil, Telugu, Malayalam, Nicobarese (Andamanese family, written in Roman), and the protected tribal languages — Andamanese, Onge, Jarawa, Sentinelese (Sentinelese is a contact-protected isolate).
