Ipsa Tripathy
Bhubaneswar: For most Odias, rivers are more than water bodies. They are part of childhood memories, religious traditions, agriculture, livelihoods, and identity itself. Rivers have shaped settlements, nourished civilizations, and sustained generations long before roads, bridges, and modern cities emerged. Yet today, standing on the banks of many rivers in Odisha, one cannot ignore a troubling question.
Are our rivers slowly losing their ability to sustain life? The concern becomes particularly visible along stretches of the Mahanadi, Odisha’s longest and most important river. In places such as Cuttack, where the river has defined the landscape and culture for centuries, large sand-covered stretches now dominate areas that once carried flowing water.
For many residents, the change is impossible to miss. The river is still there, but it no longer feels the same.
A River That Built a Civilization
The Mahanadi is often called the lifeline of Odisha. Flowing through vast stretches of the state, it supports agriculture, fisheries, industries, wetlands, and millions of people who depend on its waters directly or indirectly. The historic city of Cuttack itself owes its existence to the river system formed by the Mahanadi and Kathajodi.
For generations, these rivers have shaped the geography, economy, and culture of the region. But rivers are living systems. Their health depends not only on the amount of water flowing through them but also on the condition of their floodplains, wetlands, biodiversity, and natural channels. When these systems are disturbed, the river begins to change.
The Growing Presence of Sand
One of the most visible signs of change is the increasing dominance of sandbars and exposed riverbeds in several stretches. Sand is a natural component of river ecosystems. Rivers transport sediment as part of their natural process.
However, when large sections of a river remain dry for extended periods or when flow patterns change significantly, sand accumulation becomes more noticeable. For many people living near the Mahanadi, this has become a common sight.
What was once flowing water is increasingly replaced by broad sandy expanses, especially outside the monsoon season. Environmental observers often point to a combination of factors, including altered river flow, changing rainfall patterns, water withdrawals, and increasing human pressure on river ecosystems. The concern is not merely aesthetic. Less flowing water can affect fish populations, aquatic biodiversity, groundwater recharge, and the overall ecological health of the river.
Urbanisation and the Shrinking Space for Rivers
As Odisha develops, cities are expanding rapidly. Bhubaneswar continues to grow. Cuttack is evolving. New infrastructure projects, roads, residential areas, and commercial developments are transforming urban landscapes. Development is essential. No society can progress without improving infrastructure and creating opportunities for its people.
The challenge arises when urban growth begins to compete with natural systems for space. Across many parts of India, rivers have gradually lost sections of their floodplains to construction, encroachment, and unplanned development. Floodplains are not empty land waiting to be occupied. They are vital parts of river ecosystems that allow rivers to expand during periods of high flow and maintain ecological balance.
When rivers lose access to their natural floodplains, their ability to function as healthy ecosystems is reduced. In Cuttack, where urban development continues to increase, the relationship between the city and its rivers deserves careful attention. A city can survive without many things. It cannot survive without healthy rivers.
The Silent Impact on Biodiversity
Often overlooked in discussions about rivers is the impact on wildlife. Healthy rivers support fish, amphibians, reptiles, aquatic plants, insects, and birds. They also sustain wetlands and riparian habitats that support biodiversity far beyond the river itself. When water flow decreases or habitats become fragmented, these species face increasing pressure. A river is not simply a channel carrying water from one place to another.
It is an ecosystem. And like any ecosystem, its decline affects every life form connected to it. The disappearance of certain fish species, declining aquatic habitats, or changes in bird populations are often early warning signs of larger ecological problems.
Are Current Efforts Enough?
The Odisha government has undertaken several river-related initiatives over the years, including riverfront projects, flood management measures, conservation programmes, and water resource planning. Yet an important question remains. Are current efforts focused enough on long-term ecological health?
Managing a river involves more than controlling floods or ensuring water supply. It requires protecting natural flow patterns, conserving wetlands, preserving floodplains, monitoring biodiversity, and planning urban growth in ways that respect ecological limits. Environmental experts across the country increasingly argue that rivers must be viewed as living ecosystems rather than merely water resources.
The debate is no longer about development versus conservation. The challenge is finding a balance between the two.
Why This Matters for the Future
The consequences of neglecting river ecosystems are not immediate. They emerge gradually. A little less water each year. A few more degraded wetlands. A decline in fish populations. Reduced groundwater recharge. Greater vulnerability to floods and droughts. Over time, these small changes accumulate into larger problems. What makes the issue particularly concerning is that rivers often show signs of distress long before society fully recognizes the danger. By the time a river reaches a crisis point, restoration becomes far more difficult and expensive.
A Future Worth Protecting
The story of the Mahanadi is ultimately the story of Odisha itself. Its waters have sustained communities for centuries. Its riverbanks have witnessed the rise of cities, cultures, and livelihoods. The question facing Odisha today is not whether development should continue. Development is necessary and inevitable. The real question is whether development can proceed without compromising the very rivers that make life possible.
Because once a river loses its ability to sustain life, the consequences extend far beyond the water. They affect agriculture, biodiversity, public health, culture, and future generations. Standing on the banks of the Mahanadi today, one can still see the strength and beauty of the river. But one can also see a warning. The responsibility now lies with policymakers, planners, scientists, and citizens alike to ensure that Odisha’s rivers remain living ecosystems—not merely memories of what they once were.
