Indo-Gangetic Plain
इंडो-गंगेटिक मैदान
The Indo-Gangetic Plain is a vast alluvial plain stretching 2,400 km from the Indus River to the Bay of Bengal, encompassing northern India and Bangladesh. It is one of the world's most fertile and densely populated regions, supporting billions of people and the majority of South Asia's agriculture.
Key facts

- Width: Varies from 160 km to 320 km across its breadth
- Area: Approximately 700,000 km² (includes Pakistan and Bangladesh)
- Soil type: Alluvial deposits from Himalayan rivers, highly fertile
- Precipitation: 400-2,000 mm annually, concentrated in monsoon season
- Population: Home to over 900 million people, one of Earth's most densely settled regions
Details
The Indo-Gangetic Plain represents one of Earth's greatest concentrations of human population and agricultural productivity, formed over millennia by sediment deposits from the Ganga, Brahmaputra, Indus, and their tributaries. The plain's deep alluvial soils have supported civilizations for over 5,000 years, from the Indus Valley Civilization to modern India. Its remarkable fertility derives from annual monsoon rainfall and river flooding that replenishes soil nutrients. The region produces vast quantities of wheat, rice, sugarcane, and pulses, forming the agricultural backbone of India and Bangladesh. Ecologically, it supports diverse ecosystems including wetlands, grasslands, and riverine forests, though intensive agriculture has significantly altered original habitats. The plain also contains major water bodies like the Ganges-Brahmaputra Delta, one of the world's largest deltas, which provides fish, mangrove products, and navigation routes.
