INTRODUCTION
India, officially Republic of India (Hindi Bharat), country in southern Asia, located on the subcontinent of India. It is bounded on the north by Afghanistan, China, Nepal, and Bhutan; on the east by Bangladesh, Myanmar (formerly known as Burma), and the Bay of Bengal; on the south by the Palk Strait and the Gulf of Mannār (which separates it from Sri Lanka) and the Indian Ocean; and on the west by the Arabian Sea and Pakistan. India is divided into 28 states and 7 union territories (including the National Capital Territory of Delhi). New Delhi is the country’s capital.
The world’s seventh largest country in area, India occupies more than 3 million sq km (1 million sq mi), encompassing a varied landscape rich in natural resources. The Indian Peninsula forms a rough triangle framed on the north by the world’s highest mountains, the Himalayas, and on the east, south, and west by oceans. Its topography varies from the barren dunes of the Thar Desert to the dense tropical forests of rain-drenched Assam state. Much of India, however, consists of fertile river plains and high plateaus. Several major rivers, including the Ganges, Brahmaputra, and Indus, flow through India. Arising in the northern mountains and carrying rich alluvial soil to the plains below, these mighty rivers have supported agriculture-based civilizations for thousands of years.
With more than 1 billion inhabitants, India ranks second only to China among the world’s most populous countries. Its people are culturally diverse, and religion plays an important role in the life of the country. About 81 percent of the people practice Hinduism, a religion that originated in India. Another 13 percent are Muslims, and millions of others are Christians, Sikhs, Buddhists, and Jains. Eighteen major languages and more than 1,000 minor languages and dialects are spoken in India.
India’s long history stretches back to the Indus Valley civilization of about 2500-1700 bc. For hundreds of years, India was home to massive empires and regional kingdoms. British rule in India began in the ad 1700s. Foreign domination engendered Indian nationalism, which eventually led to India winning its independence in 1947. With independence, part of India became the new predominantly Muslim nation of Pakistan. The two nations subsequently struggled over border differences and Hindu-Muslim relations. India and Pakistan fought two wars over the Jammu and Kashmīr region, and the status of the territory remains in dispute. India’s federal political system, a democracy for more than 50 years, has demonstrated a remarkable resilience in resolving domestic and international crises. India has grown since independence to have great influence on Asia and a massive world presence. The country is a member of the Commonwealth of Nations, an association of political entities that once gave or currently give allegiance to the British monarchy.
The Indian economy has also evolved since independence. Once heavily dependent on agriculture, it has expanded in recent years into the realms of industry and services. Economic reforms in 1991 dramatically altered economic policy to privatize state-owned enterprises and to promote competition and investment. The economic focus of the country has since changed from one based on self-sufficiency to one based on trade with other countries.
LAND AND RESOURCES
India consists geographically of the entire Indian Peninsula and portions of the Asian mainland. The length of India from north to south is 3,050 km (1,900 mi); from east to west it is 2,950 km (1,830 mi). India also has two island chains, each forming its own union territory. The Andaman and Nicobar island chain lies east of the mainland between the Bay of Bengal and the Andaman Sea. Its southernmost island is only 200 km (120 mi) from the northern tip of the Indonesian island of Sumatra. The Lakshadweep island group is located off India’s southwest coast. Excluding the portions of Jammu and Kashmīr claimed by India but occupied by Pakistan or China, India has an area of 3,165,596 sq km (1,222,243 sq mi). India’s land frontier—the length of its border with other countries—measures more than 15,200 km (9,400 mi). It also has 7,000 km (4,300 mi) of coastline, including the island territories, or 5,600 km (3,500 mi) of coastline without the islands.
A. Natural Regions
India can be divided into three main regions: the Himalayas, the Gangetic Plain, and peninsular India.
The Himalayan mountain system is 160 to 320 km (100 to 200 mi) wide and extends 2,400 km (1,500 mi) along the northern and eastern borders of India. It includes the mountains surrounding the Vale of Kashmīr in the Karakoram Range, and the central and eastern Himalayas. Ancient geological forces molded the Himalayas as the Indian plate of the Earth’s crust burrowed under the Eurasian landmass, creating an uplift that continues to push this northernmost boundary of India ever higher. The Himalayan Range is the highest mountain system in the world. Among its towering summits, wholly or partly within India or within territory claimed by India and administered by Pakistan, are K2 (8,611 m/28,251 ft) and Kānchenjunga (8,598 m/28,209 ft), which are the second and third highest peaks in the world, after Mount Everest. Other prominent Indian peaks include Nanga Parbat (8,125 m/26,657 ft), Nanda Devi (7,817 m/25,646 ft), Rakaposhi (7,788 m/25,551 ft), and Kāmet peak (7,756 m/25,446 ft). The Himalayas region, including the foothills, is sparsely settled. Agriculture and animal herding are the main economic activities.
South and parallel to the Himalayas lies the Gangetic Plain, a belt of flat, alluvial lowlands 280 to 400 km (175 to 250 mi) wide. This area includes some of the most agriculturally productive land in India. The Indian portion of the broad Gangetic Plain encompasses several river systems, and stretches from Punjab state in the west, through the Gangetic Plain, to the Assam Valley in the east. Marking the western end of the Gangetic Plain are the Indus River and its tributaries, including the Sutlej and Chenāb rivers, which flow through Punjab in India’s northwest corner. The Gangetic Plain is formed by the Ganges River and its tributaries, which drain the southern slopes of the Himalayas. Assam Valley is separated from the Gangetic Plain by a narrow corridor of land near the city of Dārjiling (Darjeeling). The valley is watered by the Brahmaputra River, which rises in Tibet and crosses into India at its northeast corner, then flows north of the Khāsi Hills into Bangladesh. The Thar Desert, a huge, dry, sandy region extending into Pakistan, lies at the southwestern end of the Gangetic Plain.
South of the plains region lies peninsular India. The northern peninsula features a series of mountain ranges and plateaus. The Arāvalli Range runs in a north-south direction on the eastern edge of the Thar Desert, and low hills cut by valleys lie along the border between the states of Uttar Pradesh and Madhya Pradesh in central India. The Narmada River flows southwest between the Vindhya Range and an associated plateau on the north, and the Sātpura Range on the south. The plains of the Chota Nāgpur Plateau in the eastern states of Chhattisgarh and Jharkhand also lie within this region. The rocky and uneven lands of the northern peninsula are sparsely populated. Herding is a major occupation in the west, and farming of coarse grains such as millet is common in the central part.
In the southern part of peninsular India lies the vast Deccan Plateau, a tableland lying within a triangle formed by the Sātpura Range, the steep mountain slopes of the Western Ghats, and the gentler slopes of the Eastern Ghats. Elevations in the plateau region average 600 m (2,000 ft), although outcroppings as high as 1,200 m (4,000 ft) occur. At their northern end, the Western Ghats vary in height from 900 to 1,200 m (3,000 to 4,000 ft), but the Nīlgiri Hills of the extreme south reach a height of 2,637 m (8,652 ft) at Doda Betta, their highest peak. The Eastern Ghats lie along the eastern flank of the Deccan Plateau, interrupted by the Krishna and Godāvari river basins. Elevations of the Eastern Ghats are much lower, averaging 600 m (2,000 ft). The plateau itself, even rockier than the northern extension of peninsular India, supports a sparse agricultural population and is also home to industrial enterprises.
The Indian Peninsula is bordered by a mostly fertile seashore. The west coast, including the extensive Gujarāt Plain in the north, the thin Konkan shore in Mahārāshtra state, and the Malabar Coast in the south, support substantial populations of farmers and fishermen. Ancient trade routes to the west helped make the cities and towns of this region into market centers for textiles and spices. The east coast’s broad alluvial plains, stretching from the Kāveri River delta in the south to the Mahānadī River delta in the north, are intensely farmed.
B. Rivers and Lakes
The rivers of India can be divided into three groups: the great Himalayan rivers of the north, the westward-flowing rivers of central India, and the eastward-flowing rivers of the Deccan Plateau and the rest of peninsular India. Only small portions of India’s rivers are navigable because of silting and the wide seasonal variation in water flow (due to the monsoon climate). Water transport is thus of little importance in India. Barrages, structures that redirect water flow, have been erected on many of the rivers for irrigation, diverting water into some of the oldest and most extensive canal systems in the world.
The Indian subcontinent’s three great northern rivers, the Indus, the Brahmaputra, and the Ganges, flow through India. The Indus, about 2,900 km (1,800 mi) long, originates in the Himalayas of western Tibet, flows through the Ladakh region of Jammu and Kashmīr state, then enters Pakistan. The waters of three of its tributaries, the Sutlej, Rāvi, and Chenāb, have been diverted, under the Indus Water Treaty, for use in India. The Brahmaputra is about 2,900 km (1,800 mi) long and likewise rises in the Tibetan Himalayas. It flows through Assam state and then south through Bangladesh to the Bay of Bengal. The 2,510-km (1,560-mi) Ganges, known as Ganga in India, rises in the Indian Himalayas and enters the Gangetic Plain northeast of Delhi. At Allahābād it is joined by its major tributary, the Yamuna. The main branch of the Ganges flows through Bangladesh to the Bay of Bengal, while a second branch meets the bay in India, near Kolkata. Both the Brahmaputra and Ganges rivers discharge enormous amounts of water, almost all of it during the monsoon season.
The Narmada, at 1,289 km (801 mi) long, is India’s major west-flowing river; it flows mainly in the state of Madhya Pradesh, emptying into the Arabian Sea in Gujarāt state. Its annual runoff is less than one-tenth that of the Ganges system. Its basin consists of about 5 million cultivable hectares (about 12 million acres). A series of large dams are being constructed on the river as part of a massive development scheme to increase irrigation of the basin. One of the largest dams of the project, the Sardar Sarovar Dam, was designed to divert large amounts of water to an irrigation canal through the state of Gujarāt.
Three major rivers flow east into the Bay of Bengal, rising from the western hills of the Deccan Plateau. The northernmost is the Godāvari, about 1,400 km (900 mi) long. It has a basin (the area drained by a river) one-third the size of the Ganges, and carries one-tenth of the amount of water the Ganges carries. Emptying into the sea not far south of the Godāvari is the Krishna (about 1,300 km/800 mi), with a basin equal to the Godāvari but carrying only two-thirds of the amount of water. The smallest of the three rivers is the Kāveri (760 km/470 mi), with a basin less than one-third the size of the other two rivers.
India has a number of other significant rivers. Tributaries of the Ganges from the north include the Kosi, Gandak, Ghāghara, Gumti, and Sarda rivers. Joining the Ganges from the south are the Betwa, Chambal, and Son rivers. The Mahi, Sābarmatī, and Tāpi flow west into the Arabian Sea in Gujarāt. Flowing west to join the Indus River in Pakistan are the Beās, Chenāb, Jhelum, Rāvi, and Sutlej, all rivers of the Punjab (Hindi for “five rivers”) region of India and Pakistan. The Mahānadī and Brāhmani rivers rise in Chhattisgarh and Orissa states, respectively, and flow east to empty into the Bay of Bengal. The waters of all these rivers are used to irrigate crops, but the amount stored for purposes of irrigation and power generation varies enormously from river to river depending, among other things, on the number of dams on the river.
There are only a few natural lakes in India of any size. Chilika Lake on the coast of Orissa varies seasonally in volume and is alternately fresh and salty. Other lakes, such as Sāmbhar in Rājasthān state and Colair in Orissa state, typically dry out completely before the monsoon begins. Small, artificially created ponds called tanks are a feature of virtually every village, serving as sources of water for drinking, bathing, and irrigation.
C. Plant and Animal Life
India is home to abundant plant and animal life and has a wide range of climates that accommodate a diversity of species throughout the country. Broadly classified, there are seven major regions for plant and animal life in India: the arid Indus Plain, the Gangetic Plain, the Himalayas, Assam Valley, the Malabar Coast, the peninsular plateau, and the Andaman and Nicobar Islands.
India has an estimated 45,000 species of plants, 33 percent of which are native. There are 15,000 flowering plant species, 6 percent of the world’s total. About 3,000 to 4,000 of the total number of plant species are believed to be in danger of extinction.
In the arid areas that adjoin Pakistan, the eastern part of the Indus Plain, most plant life is sparse and herblike. Various thorny species, including capers (spiny shrubs with pale flowers) and jujubes (fruit-producing trees with veined leaves and yellowish flowers), are common. Bamboo grows in some areas, and among the few varieties of trees is the palm. The Gangetic Plain, which has more moisture, supports many types of plant life. Vegetation is especially luxuriant in the southeastern part of the plains region, where the mangrove and the sal, a hardwood timber tree, flourish.
In the Himalayas many varieties of arctic flora are found on the higher slopes. The lower levels of the mountain range support many types of subtropical plant life, notably the orchid. Dense forests remain in the few areas where agriculture and commercial forestry have had little effect. Coniferous trees, including cedar and pine, predominate in the northwestern Himalayan region. On the Himalayas’ eastern slopes, tropical and subtropical types of vegetation abound. Here rhododendrons grow to tree height. Among the predominant trees are oak and magnolia.
The Assam Valley features evergreen forests, bamboo, and areas of tall grasses. The Malabar Coast, which receives a large amount of rainfall, is thickly wooded. Evergreens, bamboo, and several varieties of valuable timber trees, including teak, predominate in this region. Extensive tracts of impenetrable jungle are found in the swampy lowlands and along the lower elevations of the Western Ghats. The vegetation of the peninsular plateau is less luxuriant, but thickets of bamboo, palm, and deciduous trees grow throughout the Deccan Plateau. The Andaman and Nicobar Islands have tropical forests, both evergreen and semievergreen.
India is inhabited by a wide variety of animal life, including almost 5,000 species of larger animals. Several species of the cat family—including the tiger, panther, Asiatic lion, Asiatic cheetah, snow leopard, jungle cat, and clouded leopard—live in some areas of India. Most of these species are under threat of extinction. Elephants roam the lower slopes of the central and eastern Himalayan foothills and the remote forests of the southern Deccan Plateau. Other large quadrupeds (four-footed animals) native to India include rhinoceros (under threat of extinction), black bear, wolf, jackal, dhole (wild Asian dog), wild buffalo, wild hog, antelope, and deer. Several species of monkeys live throughout the country.
Various species of wild goats and sheep, including ibexes and serows, are found in the Himalayas and other mountainous areas. The pygmy hog, bandicoot rat, and tree mouse are typical types of smaller native quadrupeds; bats are also abundant. Venomous reptiles, including the cobra, krait, and saltwater snake, are especially numerous in India, and pythons and crocodiles are also found. Tropical birds of India include the parrot, peacock, kingfisher, and heron. The rivers and coastal waters of India teem with fish, including many edible varieties.
D. Natural Resources
India’s most important natural resources are land and water. About 54 percent of the land area is arable, and groundwater resources are considerable. The Gangetic Plain is one of India’s most fertile regions. The soils of this region were formed by the alluvial deposits of the Ganges and its tributaries. In this area, as well as in the peninsular deltas, groundwater is plentiful and close to the surface, making year-round irrigation possible. These regions may produce two or three harvests a year. Most of India’s wheat and rice are grown here.
The black and red soils of the Deccan Plateau, although not as thick as the Gangetic Plain alluvium, are also fertile. The groundwater resources of the Deccan are significant but more difficult to reach, so most farmers rely on the monsoons for water. Farmers typically grow a single crop, including coarse grains such as sorghum, maize (corn), millet, and cotton.
Forests constitute another natural resource for India, with woodlands covering 22 percent of its land area. India’s highly varied climate and land produce diverse forests. The majority are deciduous forests, which are either tropical-dry, experiencing a significant dry season, or tropical-moist, receiving relatively uniform rainfall year-round. The remainder of forests range in type from tropical evergreen to Himalayan temperate and alpine. Major commercial tree species include teak, rosewood, and sal. Bamboo is a widely used construction material. Despite significant overuse of forest resources in the past, government and private efforts have reduced the rate of deforestation in natural forests and increased new plantations of trees, creating a modest net gain in forest cover since 1990.
The mineral resources of India include a vast belt of coal reserves stretching from the eastern part of Mahārāshtra state through Chhattisgarh and Jharkhand states to West Bengal state. The same geographical area, with the addition of Orissa state, contains major deposits of bauxite. Iron ore is also found here, as well as in the Western Ghats in and around Goa. Other mineral deposits include manganese (found mainly in central India), copper, and chromite. There are significant oil and natural gas reserves in Assam and Gujarāt states, and on the continental shelf off Mahārāshtra and Gujarāt. India also has ample reserves of phosphate rock, apatite, gypsum, limestone, and mica.
E. Climate
India’s shape, unusual topography, and geographical position give it a diverse climate. Most of India has a tropical or subtropical climate, with little variation in temperature between seasons. The northern plains, however, have a greater temperature range, with cooler winters and hotter summers. The mountain areas have cold winters and cool summers. As elevations increase sharply in the mountains, climate type can change from subtropical to polar within a few miles.
India’s seasonal cycle includes three main phases: the cool, dry winter from October to March; the hot, dry summer from April to June; and the southwest monsoon season of warm, torrential rains from mid-June to September. India’s winter season brings cold temperatures to the mountain slopes and northern plains; temperatures in the Thar Desert reach freezing at night. Farther south, temperatures are mild. Average daily temperatures in January range from 13° to 27°C (55° to 81°F) in the northeastern city of Kolkata (formerly Calcutta); from 8° to 21°C (46° to 70°F) in the north central city of New Delhi; from 19° to 30°C (67° to 85°F) in the west central coast city of Mumbai (formerly Bombay); and from 19° to 29°C (67° to 85°F) in the vicinity of Chennai (formerly Madras) on the southeastern coast. Dry weather generally accompanies the cool winter season, although severe storms sometimes traverse the country, yielding slight precipitation on the northern plains and heavy snowfall in the Himalayas.
India’s hot and dry season reaches its peak during May, when temperatures as high as 49°C (120°F) are commonly recorded in the northern plains. Temperatures in the southern peninsula are somewhat lower, averaging 35° to 40°C (95° to 104°F). At higher altitudes, as in the Western Ghats and the Himalayas, temperatures are considerably cooler.
The intense heat breaks when the summer monsoon season arrives in June. For most of the year the monsoons, or seasonal winds, blow from the northeast. In the summer months, however, they begin to blow from the southwest, absorbing moisture as they cross the Indian Ocean. This warm, moist air creates heavy rains as it rises over the Indian Peninsula and is finally forced up the slopes of the Himalayas. The rains start in early June on a strip of coast lying between the Arabian Sea and the foot of the Western Ghats. A second “arm” of the monsoon starts from the Bay of Bengal in the northeast and gradually extends up the Gangetic Plain, where it meets the Arabian Sea “arm” in the Delhi region around July 1. In July the average daily temperature range is 26° to 32°C (79° to 89°F) in Kolkata; 27° to 35°C (80° to 94°F) in New Delhi; 25° to 30°C (78° to 86°F) in Mumbai; and 26° to 36°C (79° to 96°F) in Chennai.
The monsoon season is critical to India. Farming depends heavily on the monsoon, even though artificial sources of irrigation are also commonly used. The economy prospers when the monsoon season is normal and plummets when it is not. In the past a failure of the monsoon has brought abnormally low rains in crucial food-growing regions, leading to famine. A failed monsoon season in the dryland areas of the Deccan Plateau can mean poor or nonexistent harvests for that year’s crop. In the Gangetic Plain, the groundwater needed for irrigating the winter crop depends on the monsoon for replenishing. However, an excessive monsoon may also spell disaster, especially in the Gangetic Plain of eastern Uttar Pradesh and Bihār, where rivers can flood and wash away homes and fields.
The average annual rainfall for India as a whole is 1,250 mm (49 in). The heaviest rainfall occurs along the Western Ghats, often more than 3,175 mm (125 in), and on the slopes of the eastern Himalayas and the Khāsi Hills (of Meghalaya), where the town of Cherrapunji receives 10,900 mm (430 in) annually. The entire northeast region averages more than 2,000 mm (80 in) annually, with Jharkhand, Orissa, and the Bengal region receiving nearly as much. Rain and snow fall in abundance on the entire Himalayan range. New Delhi receives an annual average of 800 to 1,000 mm (32 to 40 in) of rain, and the broad swath of land extending to the south, much of it in the rain shadow of the Western Ghats, receives about the same or a little more.
F. Environmental Issues
India’s main environmental concern is its growing population, which is expected to increase to 1.6 billion by the year 2050. In order to feed so large a population, more groundwater will be needed to irrigate crops, increasing the risk of poor soil quality due to salinization (increased salt levels). More artificial fertilizer will likely be applied to crop fields, posing threats to drinking water. The demand for meat has increased with greater levels of prosperity, resulting in overgrazing and increasing wasteland. The demand for fuelwood has grown with rural populations, leading to the loss of trees and forests. To decrease reliance on fuelwood, the government has promoted the use of biogas (a mixture of methane and carbon dioxide produced by decomposing organic matter) for cooking fuel.
Expanding agrarian population has also affected wildlife. Farmers and herders have encroached on national park and other wildlife sanctuary land, and the spread of cultivation has limited the range of animals such as tigers and elephants outside of parks as well. Poaching is also a problem. Up to 10 percent of India’s plant species are critically endangered, mainly because of the population-related pressures of deforestation and agriculture. Wetlands cover about 18 percent of the land, but most of them are under rice-paddy cultivation. To help combat these problems, the Indian government has enacted strong laws for forest conservation, wetland preservation, and wildlife protection. The Ministry of Environment and Forests was established in 1985.
India has a severe air pollution problem generated by industrial effluents and vehicle emissions. Water-treatment facilities have not kept pace with the increase in urban populations, and pollution of rivers and groundwater is a significant and worsening problem. Another major problem is toxic waste, generated by industry and deposited in rivers and oceans and on low-lying land within factory boundaries. The large number of small industrial workshops makes it difficult to enforce laws against industrial waste pollution.
A National Wildlife Action Plan provides a framework for species protection and directs the establishment of a protected areas network covering all the major habitat types for at least 4 percent of the total land area of the country. About 5 percent of the land is under protection, including 88 national parks and 490 wildlife sanctuaries established by 2003. India has a national goal of covering one-third of its land area with existing or planted forests. India has had tremendous success with species conservation. World-renowned programs include Project Tiger, which has established nine special tiger reserves, and the Crocodile Breeding and Management Project. Many nongovernmental organizations aid India’s conservation efforts.
