Ecology and Environment in Ancient India
Ancient History › Sources, Geography and Historiography · Topic 1.8
Ancient settlements depended on soil, rain, rivers and forests: deforestation with iron axes and ploughshares from about 500 BC opened the Gangetic plains, river junctions such as Pataliputra became capitals, shifts of the Sutlej and Yamuna about 1700 BC and changes in rainfall hurt Harappan and Inamgaon settlements, and ancient texts treated rivers, trees and cattle as sacred. Humans shaped nature as much as nature shaped them.

Where Does It Fit?
This is the eighth topic of the Ancient History subject. The previous topic described the land itself, and this one covers how people and nature acted on each other. The next topic covers language families. Previous topic: Geographical Setting of Ancient India (Monsoon, Rivers and Natural Frontiers).
How Did Environment and Humans Affect Each Other?
In short: the environment shaped where and how people lived, but human effort also changed it, so determinism is wrong.
Ecology, a term coined in 1869, studies the interaction of plants, animals and humans. Environment means natural surroundings (soil, air, water) and man-made ones (food, shelter, roads, bridges, dams, dwellings, and social, economic, cultural and political conditions). The environment has a direct bearing on human effort, but it is wrong to think of environmental determinism: deforestation and cereal production led to large settlements, while climate and river changes led to desertion of settlements and migration. There were no major climatic changes worldwide since 9000 BC, but regional variations occurred. Many scholars hold that extreme aridity and freezing temperature in Central Asia in the third and second millennia BC compelled people of south Central Asia to move towards the subcontinent, a migration attributed to Indo-Aryan speakers and the Rig Vedic people. The earliest settlements in India were near lakes or rivers in hilly, plateau or wooded areas where stone and bone tools could be made.
How Did Surroundings Decide Settlements?
| Factor | Effect |
|---|---|
| Iron | Large agricultural settlements in the Gangetic plains were nearly impossible without deforestation and ploughing hard alluvium, which needed the iron axe and ploughshare from about 500 BC; the red soil of the Vindhyan zone and black cotton soil of the Deccan also needed iron shares |
| Favourable zones | Rain, rivers, lakes, forests, hills, minerals and fertile soil attracted settlers; arid deserts without water discouraged them; the Gangetic plains were attractive |
| Rivers | Served as roads and railways; floods washed away forested banks and irrigated land |
| River junctions | Cleared forests and aided habitation; Pataliputra lay at the junction of the Ganges and Son with the Gandak, Ghagra and Punpun nearby, a virtual water port and the first great state capital; Chirand lay at the junction of the Ganges and Ghaghara, where antler tools show deer hunting |
| Lakes and tanks | Settlements near them in eastern UP and north Bihar in the second millennium BC |
Forests in the doab survived despite deforestation until the sixteenth and seventeenth centuries, when wild animals were hunted there. Changes in river courses affected settlements about 2500 BC: the Sarasvati (the Ghaggar-Hakra) was joined by the Yamuna and Sutlej and the three contributed to Harappan growth, but about 1700 BC the Sutlej, and possibly the Yamuna, moved east, adversely affecting post-urban Harappan settlements. The consequences are in Decline of the Indus Civilisation.
What Role Did Rain and Natural Hazards Play?
The Harappan culture lay in an arid, semi-desert zone, but scientists speak of adequate rainfall there in the third millennium BC, and when rainfall returned to its usual level the settlements suffered. Plant and animal remains from Inamgaon in Maharashtra suggest an extremely arid phase about 1000 BC that forced farmers to abandon their homes for pastoral nomadism. Heavy monsoon rain deterred regular work: the Buddha suspended his teaching for four months each rainy season and stayed at Rajagriha, Vaishali and Shravasti for varsha-vasa, spending twenty-six rainy seasons at Shravasti. Floods, hurricanes and earthquakes were more catastrophic than rain. A famine is said to have led some Jainas to migrate from Magadha to south India in pre-Mauryan times, but sources on natural hazards are scarce.
How Did Ancient Indians View Nature?
Rivers came to be regarded as divine: the Rig Veda depicts the Sarasvati as a goddess, and in post-Vedic times the Ganga emerged as the mother goddess. Earth and water were considered mothers, though there is nothing to show plans to protect them. Many trees and plants, including neem, pipal, vat, shami and tulsi, are sacred and valued for medicinal properties, and at the end of rituals priests wish peace and prosperity to forest trees and plants. Many ancient texts condemn the slaughter of animals; the Buddha in the Suttanipata was the first to stress the protection of cows, which help to grow plants and provide food, and in the early Christian centuries brahmanical texts gave religious colour to this teaching. Later even the elephant came to be worshipped. As an analytical point, society advanced at the cost of plants and animals, since the struggle against nature was mainly directed at them, and then humans multiplied both. History is the record of that continuing interaction, as seen in Neolithic and Chalcolithic settlements of The Neolithic Age – First Food Producers.

Memory Hook
Iron clears, rivers join, junctions grow; rain comes and goes; rivers, trees and cows become sacred.

Frequently Asked Questions
What is meant by environmental determinism?
Environmental determinism is the idea that nature alone decides human history. Historians reject it, since human effort changed the surroundings: deforestation and cereal farming created large settlements, while shifts in climate and rivers also forced desertion and migration.
Why was iron important for the Gangetic plains?
The hard alluvial soil and thick forests of the middle and lower Gangetic plains could be cleared and ploughed effectively only with the iron axe and ploughshare, used widely from about 500 BC, which allowed numerous settlements to be founded.
Why was Pataliputra well placed?
Pataliputra lay at the junction of the Ganges and the Son, with the Gandak, Ghagra and Punpun joining nearby. Rivers on three sides made it virtually a water port, which helped it become India's first great state capital.
How did climate change affect early settlements?
Rainfall that was adequate in the Harappan area in the third millennium BC later returned to its normal level, harming settlements. At Inamgaon an extremely dry phase about 1000 BC forced farmers to desert their homes and turn to pastoral nomadism.
How did ancient Indians regard nature?
They treated rivers like the Sarasvati and Ganga as divine, regarded neem, pipal, vat, shami and tulsi as sacred, and condemned animal slaughter. The Buddha stressed protecting cows, and brahmanical texts later gave this religious force.
