Ganges

The Ganga (Hindustani: [ˈɡəŋɡaː]) , also Ganges (/ˈɡændʒiːz/ GAN-jeez) is a trans-boundary river of Asia which flows through the nations of India and Bangladesh. The 2,525 km (1,569 mi) river rises in the western Himalayas in the Indian state of Uttarakhand, and flows south and east through the Gangetic Plain of North India into Bangladesh, where it empties into the Bay of Bengal. It is the third largest river by discharge.

The Ganga is the most sacred river to Hindus. It is also a lifeline to millions of Indians who live along its course and depend on it for their daily needs. It is worshipped as the goddess Ganga in Hinduism. It has also been important historically, with many former provincial or imperial capitals (such as Pataliputra,Kannauj,Kara, Kashi, Patna, Hajipur, Munger, Bhagalpur, Murshidabad, Baharampur, Kampilya, and Calcutta) located on its banks.

The Ganga was ranked as the fifth most polluted river of the world in 2007. Pollution threatens not only humans, but also more than 140 fish species, 90 amphibian species and the endangered Ganga river dolphin. The Ganga Action Plan, an environmental initiative to clean up the river, has been a major failure thus far, due to corruption, lack of technical expertise, poor environmental planning, and lack of support from religious authorities.

Indo-Gangetic Plain

The Indo-Gangetic Plain, also known as Indus-Ganga and the North Indian River Plain, is a 255 million hectare (630 million acre) fertile plain encompassing most of northern and eastern India, the eastern parts of Pakistan, and virtually all of Bangladesh. The region is named after the Indus and the Ganges, and encompasses a number of large urban areas. The Indus-Ganga plain is bound on the north by the Himalayas which feed its numerous rivers and are the source of the fertile alluvium deposited across the region by the two river systems. The southern edge of the plain is marked by the Chota Nagpur Plateau. On the west rises the Iranian Plateau.

History

The region is known for the Indus Valley Civilization, which was responsible for the birth of ancient South Asian culture. The flat and fertile terrain has facilitated the repeated rise and expansion of various empires, including the Gupta empire, Kanauj, Magadha, the Maurya Empire, the Mughal Empire and the Sultanate of Delhi – all of which had their demographic and political centers in the Indo-Gangetic plain. During the Vedic and Epic eras of Indian history, this region was referred to as "Aryavarta" (Land of the Aryans) which was bordered on the west by the Indus river, on the east by Anga region of present-day easternmost part of Bihar and doorstep of Bengal and on the south by the Vindhya Mountain range. During the Islamic period, the Turkish, Afghan and Iranian rulers referred to this region as "Hindustan" (Land of the Hindus), deriving from the Persian term for the Indus River. This term was later used to refer to the whole of India but even into the modern era, the dialect of Hindi-Urdu spoken in this region is called Hindustani, a term which is also used for the local music and culture.
