Indo-Gangetic Plain

The Indo-Gangetic Plain, also known as the North Indian Plain or the Indus-Gangetic Plain, is a fertile plain spanning 700,000 km (270,000 sq mi) across the northern and north-eastern part of the Indian subcontinent. It encompasses northern and eastern India, eastern Pakistan, southern Nepal, and almost all of Bangladesh. It is named after the two major river systems that drain the region–Indus and Ganges.

It stretches from the Himalayas in the north to the northern edge of the Deccan Plateau in the south, and extends from North East India in the east to the Iranian border in the west. The region is home to many major cities and nearly one-seventh of the world's population. As the region was formed by the deposits of the three major rivers–Indus, Ganges and Brahmaputra, the plains consist of the world's largest expanse of uninterrupted alluvium. Due to its rich water resources, it is one of the world's most densely populated and intensely farmed areas.
