Geography of India India occupies the central-southern part of South Asia and spans diverse landscapes from the high Himalayas in the north to the peninsular plateau of Deccan Plateau in the south. Its strategic position between the Arabian Sea and the Bay of Bengal and proximity to the Indian Ocean have shaped interactions with neighbors such as Pakistan, Bangladesh, Sri Lanka, and Myanmar and influenced historic connections with Persia, Arabia, Southeast Asia, and East Africa.

Overview

India's territorial extent includes the subcontinental features of the Indo-Gangetic Plain, the Thar Desert, the Western Ghats, and the Eastern Ghats, with major river systems—Ganges, Brahmaputra, Yamuna, Godavari, Krishna—forming lifelines for population centers like Kolkata, Delhi, Chennai, Bengaluru, and Hyderabad. The political map comprises states and union territories including Uttar Pradesh, Maharashtra, Bihar, West Bengal, Karnataka, and Tamil Nadu, while sensitive border regions near Aksai Chin, Ladakh, Siachen Glacier, and the Line of Actual Control involve China and Pakistan.

Physical Geography

The northern boundary is dominated by the Himalayas—including ranges such as the Karakoram and ranges containing peaks like K2 (disputed with Pakistan), Nanda Devi, and Kanchenjunga (shared with Nepal). The Indo-Gangetic Plain fed by the Ganges and Brahmaputra supports dense agrarian zones in provinces like Punjab and Bihar. Peninsular India features the Deccan Plateau with the Vindhya and Satpura ranges and the mineral-rich Chota Nagpur Plateau. Coastal plains run along the Malabar Coast and Coromandel Coast with the Lakshadweep and Andaman and Nicobar Islands in the Indian Ocean and Bay of Bengal. The Thar Desert stretches across Rajasthan into Sindh (Pakistan). Major lakes include Chilika Lake and Vembanad Lake, while wetlands such as the Sundarbans mangrove complex lie at the Ganges delta.

Climate

India's climate ranges from alpine in the Karakoram and Himalaya to tropical in the Andaman and Nicobar Islands, with major climatic controls being the Indian Monsoon, the Southwest Monsoon, and the Northeast Monsoon. Seasonal variability produces phenomena such as the Monsoon trough, El Niño–Southern Oscillation influences, and cyclones forming in the Bay of Bengal and Arabian Sea that impact coastal cities like Visakhapatnam, Chennai, Kolkata, and Ahmedabad. Climatic zones defined by the Köppen climate classification include humid subtropical zones in Punjab and West Bengal, tropical wet and dry regions in Maharashtra and Karnataka, and arid zones in Rajasthan.

Biodiversity and Ecosystems

India's biogeographic realms include the Indomalayan realm and hotspots like the Western Ghats and Eastern Himalaya, hosting endemic species such as the Bengal tiger, Indian elephant, Asiatic lion, one-horned rhinoceros (found in Kaziranga National Park), and the Indian rhinoceros. Protected areas include Jim Corbett National Park, Sundarbans National Park, Gir National Park, Bandipur National Park, and Periyar Wildlife Sanctuary. Forest types range from tropical moist broadleaf forests to montane forests and dry deciduous forests; mangrove belts such as the Sundarbans are critical for species like the saltwater crocodile and migratory birds that visit Pulicat Lake and Bharatpur (Keoladeo National Park). Conservation frameworks involve statutes such as the Wildlife Protection Act, 1972 and institutions like the Zoological Survey of India and Botanical Survey of India.

Regional Divisions

Administratively, India is divided into regions commonly referenced as North India (including Punjab, Haryana, Uttar Pradesh, Jammu and Kashmir), South India (including Tamil Nadu, Kerala, Andhra Pradesh, Telangana'), East India (including West Bengal, Odisha', Bihar), West India (including Maharashtra, Gujarat), and Northeast India (including Assam, Arunachal Pradesh, Manipur, Mizoram, Nagaland, Meghalaya', Tripura). Economic and cultural hubs such as Mumbai, Kolkata, New Delhi, Hyderabad, and Bengaluru sit within these regions and connect through transport corridors like the Golden Quadrilateral and ports such as Mumbai Port, Kandla, Chennai Port, and Visakhapatnam Port.

Natural Resources and Land Use

India's geology hosts deposits of coal in the Damodar Valley and Singrauli Basin, iron ore in the Bailadila and Bellary regions, bauxite in Odisha and Jharkhand, and petroleum in offshore fields near Mumbai High and onshore basins in Assam and Gujarat. Agricultural tracts in the Indo-Gangetic Plain produce staples like rice and wheat, while cash crops such as cotton in Maharashtra and tea in Assam and Darjeeling support agro-industries. Land-use pressures affect regions such as the Western Ghats and Sundarbans, with irrigation works like the Bhakra Nangal Dam and river-linking proposals altering hydrology of rivers including the Narmada and Kaveri.

Environmental Issues and Conservation

India faces environmental challenges including air pollution episodes in Delhi and Kanpur, water pollution in the Ganges and Yamuna, deforestation in the Western Ghats, and coastal erosion along the Bay of Bengal. Natural hazards include floods in Bihar and Assam, cyclones impacting Odisha and Andhra Pradesh, droughts in Rajasthan and Maharashtra, and glacial retreat in the Himalaya with implications for rivers like the Indus. Policy and conservation responses involve agencies such as the Ministry of Environment, Forest and Climate Change, initiatives like Project Tiger, Ramsar designations at sites like Keoladeo National Park and Chilka Lake, and judicial interventions by the Supreme Court of India on environmental clearances.
