Environment

Location

India occupies much of the South Asian

subcontinent, and the Indian mainland stretches

eastward from Pakistan in the west to Bangladesh

and Burma in the east. On the north, India borders

China, Nepal, and Bhutan. The Indian Ocean to the

south, the Arabian Sea to the west, and the Bay of

Bengal to the east form the country’s coastline.

Noncontiguous to the mainland are the Lakshadweep

Islands in the Arabian Sea and the Andaman and

Nicobar Islands located 1,300 kilometers from the

mainland in the Bay of Bengal.

Size

The country’s exact size is subject to debate

because some borders are disputed. The Indian government lists the total area as 3,287,260 square kilometers and the total land area as 3,060,500 square kilometers; the United Nations lists the total area as 3,287,263 square kilometers and total land area as 2,973,190 square kilometers. In either case, India is the seventh largest country in the world and about one-third the size of the United States.

Land Boundaries

Land boundaries total 15,200 kilometers. India shares common borders with Pakistan (3,325 kilometers; the Jammu and Kashmir border is 1,085 kilometers), China (line of

  actual control is 3,439 kilometers), Bhutan (605 kilometers), Nepal (1,690 kilometers), Burma (1,452 kilometers), and Bangladesh (4,339 kilometers). Although India and Sri Lanka do not share a land boundary, the narrowest distance between the two countries is only 64 kilometers across the Palk Strait.

Disputed Territory

Most of Jammu and Kashmir is contested with Pakistan, and the Aksai Chin area of Jammu and Kashmir is disputed with China, as is the border of Arunachal Pradesh state in northeast India. Nepal claims a 75-square-kilometer-area called Kalapani. Possession of recently emerged New Moore Island (South Talpatty) in the Bay of Bengal has been disputed by Bangladesh, and much of the border with Bangladesh is not demarcated.

Length of Coastline

India’s total coastline is 7,516 kilometers in length, which comprises 5,422 kilometers for the mainland, 132 kilometers for the Lakshadweep Islands, and 1,962 kilometers for the Andaman and Nicobar Islands.

Maritime Claims

Under the 1982 United Nations Convention on the Law of the Sea, India has a 200-nautical-mile exclusive economic zone, a 12-nautical-mile territorial sea, a 24-nautical-mile contiguous zone, and a legal continental shelf extending to a depth of 2,500 meters or to the end of the continental margin.

Topography

There are three main geological regions: the Indo-Gangetic Plain and the Himalayas—collectively known as North India—and the Peninsula, or South India. These and other portions of India can be classified into diverse physiological regions that include highlands, plains, deserts, and river valleys. The country’s lowest elevation is zero meters at the Indian Ocean, and the highest is 8,598 meters at Kanchenjunga, which is the third highest mountain in the world and located in the Himalayas.

Principal Rivers

India’s longest rivers are the Brahmaputra and Indus, which are both 2,896 kilometers long, although neither is entirely within India. Other major rivers are the Ganga (Ganges, 2,525 kilometers), Godavari (1,465), Kaveri (Cauvery, 800), Krishna (1,401), Mahanandi (851), Narmada (1,312), and Yamuna (1,370).

Climate

Climate in India varies significantly from the permanently snow-capped Himalayas in the north to the tropics in the south. The country has four seasons. December to February is relatively dry and cool, March to May is dry and hot, from June to September predominating southwest maritime winds bring monsoon rains to most of the country, and in October and November there are retreating dry monsoons originating from the northeast. Average temperatures range from 12.5° C to 30° C in the northwest, 17.5° C to 30° C in the north and northeast, and 22.5° C to 30° C in the south. Average annual rainfall is around 1,000 to 1,500 millimeters for much of the country, but can be quite low in some parts of the northwest (150 to 300 millimeters annually) and very high in the northeast and along the west coast (1,500 to 2,500 millimeters annually).

Natural Resources

Commercially important natural resources include arable land, bauxite, chromite, coal (fourth-largest reserves in the world), diamonds, iron ore, limestone, manganese, mica, natural gas, petroleum, and titanium ore.

Land Use

In 2000 the total arable land and land planted under permanent crops combined was 1,697,000 square kilometers, and total irrigated land was 548,000 square kilometers. The total of non-arable land and land not under permanent crops was 1,276,190 square kilometers.

Environmental Factors

India is vulnerable to various natural hazards, particularly cyclones and annual monsoon floods, and various combinations of poverty, population growth, increasing individual consumption, industrialization, infrastructural development, poor agricultural practices, and resource maldistribution have led to substantial human transformation of India’s natural environment. An estimated 60 percent of cultivated land suffers from soil erosion, waterlogging, and salinity. It is also estimated that between 4.7 and 12 billion tons of topsoil are lost annually from soil erosion. From 1947 to 2002, average annual per capita water availability declined by almost 70 percent to 1,822 cubic meters, and overexploitation of groundwater is problematic in the states of Haryana, Punjab, and Uttar Pradesh. Forest area covers 19.4 percent of India’s geographic area (63.7 million hectares). Nearly half of the country’s forest cover is found in the state of Madhya Pradesh (20.7 percent) and the seven states of the northeast (25.7 percent); the latter is experiencing net forest loss. Forest cover is declining because of harvesting for fuel wood and the expansion of agricultural land. These trends, combined with increasing industrial and motor vehicle pollution output, have led to atmospheric temperature increases, shifting precipitation patterns, and declining intervals of drought recurrence in many areas. The Indian Agricultural Research Institute has estimated that a 3° C rise in temperature will result in a 15 to 20 percent loss in annual wheat yields. These are substantial problems for a nation with such a large population depending on the productivity of primary resources and whose economic growth relies heavily on industrial growth.

Civil conflicts involving natural resources—most notably forests and arable land—have occurred in eastern and northeastern states. By contrast, water resources have not been linked to either domestic or international violent conflict as was previously anticipated by some observers. Possible exceptions include some communal violence related to distribution of water from the Kaveri River and political tensions surrounding actual and potential population displacements by dam projects, particularly on the Narmada River.

Time Zones

All of India is under a single time zone, which is Greenwich Mean Time plus 5.5 hours.
