Indo-Gangetic Plain

geography Maturity 11-13 Next article →

The Indo-Gangetic Plain is a massive, fertile lowland in northern and north-eastern India. It is also called the North Indian Plain or the Indus-Gangetic Plain. This region covers parts of northern and eastern India, eastern Pakistan, southern Nepal, and almost all of Bangladesh.

It stretches from the high Himalayas in the north to the Deccan Plateau in the south. To the east, it reaches North East India. To the west, it extends to the Iranian border. This area is incredibly important because it holds nearly one-seventh of the world's population.

The plain was created by the continuous deposition of silt by three major river systems. These rivers are the Indus, the Ganges, and the Brahmaputra. Over a long time, these rivers carried fine soil called alluvium into a large depression. This depression sits between the mountains in the north and the plateau in the south. Geologists have different ideas about how this low area formed. Some thought it was a deep rift in the Earth's crust. Others suggested it was a large syncline formed by the moving Himalayas. Recent research suggests the northward drift of the Indian plate created a trough. This trough was eventually filled with sediment from the ancient Tethys Sea. This process created the world's largest expanse of uninterrupted alluvium.

The landscape is organized into four distinct geographical strips. The first is the Bhabar, a narrow strip right below the Himalayan foothills. It is very porous and made of stones and rocks. Because of this, many streams actually disappear underground here. The second strip is the Terai, which lies next to the Bhabar. This area is made of new silt and receives heavy rains. It is covered in thick, wet, evergreen vegetation. The third region is the Bangar, which consists of older alluvium. This is a major fertile area of the flood plains. The final region is the Khadir, which contains low-lying areas. Khadir is composed of new silt carried by rivers in the upper plains.

History in this region began very early with the Indus Valley Civilisation. This settlement existed around 3000 BCE.

During the Vedic period, between 1500 and 600 BCE, the area was called Aryavarta. This name meant the land between the Himalayas and the Vindhya ranges. The fertile land allowed many great empires to rise and expand. The Mauryas ruled from the 4th to the 2nd century BCE. They created the largest empire ever to exist on the Indian subcontinent. The Kushan Empire expanded into the northwest during the 1st century CE. Later, the Gupta period from the 4th to the 7th century CE became famous for science and arts.

Many different powers competed for control of these fertile plains over many centuries. In the 12th century, the Rajputs ruled much of the land. After the Second Battle of Tarain, the Delhi Sultanate rose in the 13th century. In 1526, Babur established the Mughal Empire, which lasted for nearly three hundred years. Other groups like the Maratha Empire and the Sikh Empire also held power. Eventually, the English East India company gained control through battles in 1757 and 1764. This consolidated their power in the lower Gangetic plain. The entire region eventually came under the British Raj. This lasted until the Indian Independence in 1947.

The climate and water resources vary greatly across the vast plain. The eastern part receives much more rainfall than the western part. This rain often comes during the summer monsoon and causes frequent floods. In the west, the land becomes much drier. This area includes the Thar Desert, which covers a massive area.

In the drier western sections, farmers grow wheat, barley, and millet. In the wetter east and north, rice is the most common crop. The Indus River eventually flows into the sea at the Indus Delta.

This delta contains the largest arid mangrove forests in the world.

The plain can be divided into several smaller geographical units. The western part includes the Sindh Plains and the Indus Delta in Pakistan. The Rajasthan Plain and the Punjab-Haryana Plain are located in India and Pakistan. The Ganga Plain covers much of India and Bangladesh. There is also the Brahmaputra Valley in India and the Terai in Nepal. The Ganges-Brahmaputra Delta is another major unit in India and Bangladesh.
