Dadra and Nagar Haveli and Daman and Diu

மாநில மேலோட்டம்

Dadra & Nagar Haveli and Daman & Diu — merged into a single Union Territory on 26 January 2020 — is an aggregation of former Portuguese possessions covering 603 km² in three non-contiguous parts on the western coast: Dadra & Nagar Haveli (an inland hilly enclave between Gujarat and Maharashtra, Western Ghats foothills, ~62% tribal — predominantly Warli, Dhodia, Kokna communities), Daman (a coastal pocket north of the Gulf of Khambhat), and Diu (an island off Saurashtra coast). The UT was Portuguese territory until 1954 (DNH) and 1961 (Daman/Diu), with strong cultural-architectural legacy.

The UT's agriculture splits across three contexts. DNH is tribal rainfed — Warli and Dhodia farmers cultivate paddy, nagli (finger millet/ragi), banti, cucurbits, pulses, and harvest non-timber forest produce (mahua, tendu, lac); the Warli Art tradition derives its iconography from these agricultural cycles. Daman is coastal — paddy in the Daman Ganga floodplain, coconut along the shore, mango and chiku orchards inland. Diu is semi-arid coral-island — minor banana, coconut and onion cultivation, with significant dependence on Saurashtra trade. The Madhuban Dam supports DNH irrigation. The Tribal Sub-Plan funds 70% of the agricultural budget in DNH. Note: Cultivation footprint modest — guide ~800 words.

மண் வகைகள்

DNH soils are red-yellow lateritic (Western Ghats foothills, supporting tribal millet and pulse cultivation) and alluvial along the Daman Ganga river valley. Daman-Diu soils are coastal sandy and alluvial — supporting coconut, banana and vegetables.

நீர் வளம்

Rainfall 2200 mm in DNH (heavy monsoon), 1800 mm in Daman, 600 mm in Diu (semi-arid). Madhuban Dam on the Daman Ganga serves DNH; Daman uses small reservoirs; Diu is groundwater-dependent and stressed.

பிகா மாற்றம்

In Dadra & Nagar Haveli and Daman & Diu, one bigha ≈ 0.4 acres (17,427 sq ft). Vigha = bigha. See the area unit converter for instant conversions to acres, hectares, guntha, gaj and katha.

Cropping calendar

DNH-DD: Kharif paddy (DNH tribal belt) sown June-July, harvested October-November. Nagli (finger millet) sown June, harvested October. Mango (Silvassa) flower January, harvest April-June. Coconut (Daman) continuous. Banana (Diu) continuous.

MSP procurement & mandi network

Minor cereal procurement. Tribal Sub-Plan agriculture drives DNH (62% tribal population — Warli, Dhodia, Kokna, Naika).

District-wise crop concentrations

3 regions of the merged UT: DNH (Silvassa — tribal hilly), Daman (coastal — Daman Ganga floodplain), Diu (semi-arid coral island off Saurashtra). The Warli Art tradition is internationally recognised — derived from agricultural-ritual iconography.

Climate-resilience & soil-test interpretation

DNH faces monsoon flooding (Daman Ganga 2017), Diu faces drought. Madhuban Dam is DNH's main reservoir. Tribal-resilience programmes target nagli millet revival and mahua-tendu value chains. Note: UT cultivation footprint modest — guide ~800 words.

உள்ளூர் மொழி

Gujarati (Gujarati script) and Hindi (Devanagari) are official in DNH; Gujarati dominates in Daman-Diu. Konkani has historical use in Diu (Portuguese-era). The tribal Warli community (DNH) speaks Warli (a Konkani-Bhili creole) and is internationally famous for Warli art — geometric tribal painting tradition.
