The city rose, The river shrank!
Imagine a grandfather standing on the banks of the river Yamuna in Delhi, holding his grandson’s hand. He says, "Son, when I was your age, the river used to reach till here." The grandson looks in disbelief. Where the grandfather is pointing to the river, today there are roads, buildings and concrete. Did the river really move back, or did we push it back?
According to a study conducted by the Indian Institute of Technology Delhi in collaboration with the Delhi government, in the last 225 years the Yamuna’s width within Delhi has shrunk by about 68%, and its natural water flow has reduced by about 89%. The study used historical maps, satellite images and geospatial (GIS) analysis from 1799 to 2024.
During this period, Delhi’s urban sprawl has multiplied many times over. Construction on the floodplain, embankments, roads, real estate projects and continuous encroachment have all restricted the river’s natural spread. As a result, the river has kept shrinking, groundwater recharge has decreased, and the risks of floods and pollution have gone on rising.
Experts say that the Yamuna is not just a water channel, but the lifeline of Delhi’s ecology. The shrinking of the river is not only a water crisis; it is also a crisis of biodiversity, climate adaptation, local temperature, groundwater, and the water security of future generations. The loss of the river’s floodplain can make future extreme rainfall events far more destructive.
The question is not just, "Why has the Yamuna shrunk?" The real question is: does development mean advancing by erasing nature? If every city writes the same fate for its river, then coming generations will read about rivers in history books, not see them in their own cities.
This is not the river’s problem; it is humanity’s problem. The ego wants to fill every empty space with its own achievements. Open skies, forests, rivers or floodplains appear useless to it, because in its eyes only that is valuable which can be bought, sold, and built upon. This very ignorance turns nature into a mere resource.
Pause and ask yourself: are we really building cities, or are we destroying the very foundations of our own lives? If the death of the river is necessary for our development, then is it truly development at all, or is it just the ego expanding itself to stuff its inner emptiness with external objects?
