From Cleaner Rivers to Healthier Rivers

A river can look clean and still be unhealthy. Water may meet prescribed standards while native fish disappear, seasonal flows change, floodplains shrink and groundwater connections weaken. New pollutants may go undetected. A river is more than water flowing between two banks; cleaning it is necessary, but does not by itself restore its health.

From Cleaner Rivers to Healthier Rivers

A river can look clean and still be unhealthy. Water may meet prescribed standards while native fish disappear, seasonal flows change, floodplains shrink and groundwater connections weaken. New pollutants may go undetected. A river is more than water flowing between two banks; cleaning it is necessary, but does not by itself restore its health. As India looks towards Viksit Bharat@2047, the focus must shift from water quality to river health. Programmes such as Namami Gange are already moving beyond pollution control towards biodiversity conservation, ecological flows and biological monitoring. The next measure of restoration should be whether a river is functioning as a living ecosystem. Beyond Clean Water The Central Pollution Control Board’s 2025 assessment, based on monitoring during 2022 and 2023, identified 296 polluted stretches across 271 rivers, compared with 351 polluted stretches identified in 2018. These figures describe pollution, and not river health. Suppose a river meets prescribed standards while its natural flow declines, native fish disappear or its floodplain is built over. Would we call it healthy? No physician would declare a person healthy after measuring blood glucose alone. Rivers, too, need a broader assessment that includes flow, aquatic life, sediments, groundwater and floodplains. European and Australian programs recognize this approach. Scientists at IIT (BHU) have developed and tested a River Health Index for the Ganga at Varanasi, bringing together measures of river condition across locations and seasons. Subsequent research has examined pharmaceutical pollutants and biological responses involving algae, small aquatic animals and fish. Aquatic organisms experience river conditions continuously. A water sample tells us what was present when it was collected; changes in aquatic life can reveal what has been happening over time. Emerging threats include medicine residues, personal care chemicals, microplastics and antimicrobial resistance. Studies of Indian rivers have detected antibiotic-resistant bacteria and genes associated with antibiotic resistance in water and sediments. Sewage, hospital waste, agricultural runoff and industrial discharges can introduce these threats into rivers, linking the health of people, animals and the environment. This is where the One Health approach becomes relevant. High flows, low flows and seasonal floods move sediments, create habitats, connect floodplains and support aquatic life. In many rivers, groundwater helps maintain flow during dry periods. In monsoon-dominated India, when and how water flows matter as much as its quantity. We often try to restore rivers by working on the rivers themselves. Yet many problems begin far from their banks. Deforestation and farming change runoff and erosion. Urban growth reduces the amount of rainwater entering the ground. Excessive groundwater pumping can reduce river flows. Dams alter water and sediment movement, while sand mining and construction damage riverbeds and floodplains. A river cannot ultimately be healthier than the basin that sustains it. Restoration must include tributaries, wetlands, groundwater, vegetated riverbanks and natural drainage routes, not merely treatment plants and riverfronts. The Sahibi illustrates this challenge. Rising in Rajasthan and passing through Haryana before entering Delhi, it has undergone major changes in its flow and surrounding landscape. Its links with Najafgarh Jheel and the Najafgarh Drain show how urban growth, sewage, altered flows and drainage works become intertwined. Treating water in its channel alone cannot restore the wider river system. India’s rivers also differ greatly. A Himalayan river fed by snow, glaciers and monsoon rain cannot be assessed exactly like a seasonal river in Rajasthan or a dam-regulated peninsular river. We need common principles, but different measures and restoration goals for different rivers. Climate change makes this task harder. Unpredictable rainfall, longer dry periods and extreme floods can alter flows, water quality and habitats. Restoration plans must account for these changes, while monitoring should tell us whether improvements last. Viksit Bharat@2047 offers an opportunity to establish a national River Health@2047 framework. It should examine water and sediment quality; natural flow patterns; aquatic life; the condition of riverbeds and floodplains; and the relationship between rivers and the people who depend on them. River Health Index These aspects tell us what to measure. But measurement alone cannot restore a river. Rivers need sufficient water through their natural seasonal cycles, supported by groundwater where appropriate. Pollution must be reduced and wastewater treated. Floodplains, wetlands and natural drainage routes must be protected. Aquatic habitats, biodiversity and connections within river systems must be restored. Farming, groundwater use, urban growth and industry must be managed without steadily damaging rivers. Governments, communities, universities, civil society and businesses must work together, with clear responsibilities for monitoring, protecting and restoring them.
A River Health Index can bring measurements together and identify where a river is under stress, why and what might help. Success must be measured by checking whether natural flows have returned and if aquatic life has recovered. Scientific findings must guide decisions about water use, land use and floodplain protection. Otherwise, even sophisticated measurements will achieve little. Importantly, restoration cannot remain the responsibility of scientists and government agencies alone. Technology cannot replace the knowledge of people who live beside rivers. Their observations of changing flows, disappearing fish and shrinking wetlands can help scientists judge whether restoration is working. This is the spirit behind Bharat Discourses on Rivers@2047: Connecting Science with the Society which begins on October 3 at IIT (BHU). The event raises vital questions. What should be different about Indian rivers by 2047? How will we know their health has improved? What is holding us back, and what must we do differently? Most importantly, what one or two actions should begin by 2027 to achieve our goals? Healthy rivers sustain biodiversity and livelihoods, recharge groundwater, carry sediments and accommodate floods. They are not an environmental luxury to consider after development; they are essential to development itself. We must leave the next generation not merely cleaner stretches of water, but living, resilient rivers. The question for 2047 is not simply, “Is our river cleaner?” It is, “Is our river healthier, and is its health continuing to improve?” (Dr. Singh is a Professor of Civil Engineering, Indian Institute of Technology (BHU), Varanasi; Dr. Paknikar is the ANRF Prime Minister Professor, COEP Technological University, Pune.

India working on logistics of Tahawwur Rana's extradition

Tahawwur Rana

Washington: India is working on the logistics of Tahawwur Rana's surrender and extradition from the US, Foreign Secretary Vikram Misri has said, as President Donald Trump announced that his administration has given the go-ahead to extradite the 26/11 terror attack accused “to face justice".

“This is an issue on which the US authorities have taken very clear decisions. I think you've seen the President announce it himself from the White House podium" the decision of the US to extradite Rana, Misri said at a press conference here on Thursday.


During a joint press conference with Prime Minister Narendra Modi in the White House, US President Donald Trump announced that his administration has approved the extradition of "very evil" Tahawwur Rana, wanted by Indian law enforcement agencies for his role in the 26/11 Mumbai terror attacks, "to face justice in India”.


In response to a question by PTI on the timeframe by when Rana will be extradited to India, Misri said: "We are working on the logistics of his surrender and extradition to India. There are a few final steps to be completed. The two sides are in touch on this particular issue.”


The India-US joint statement issued during the Prime Minister's visit to the US notes that Modi and Trump reaffirmed that the global scourge of terrorism must be fought and terrorist safe havens eliminated from every corner of the world.

“They committed to strengthen cooperation against terrorist threats from groups, including Al-Qaeda, ISIS, Jaish-e Mohammad, and Lashkar-e-Tayyiba in order to prevent heinous acts like the attacks in Mumbai on 26/11 and the Abbey Gate bombing in Afghanistan on August 26, 2021," the joint statement said.


“Recognising a shared desire to bring to justice those who would harm our citizens, the US announced that the extradition to India of Tahawwur Rana has been approved," it said.


The leaders further called on Pakistan to expeditiously bring to justice the perpetrators of the 26/11 Mumbai, and Pathankot attacks and ensure that its territory is not used to carry out cross-border terrorist attacks.

"The leaders also pledged to work together to prevent the proliferation of weapons of mass destruction and their delivery systems and to deny access to such weapons by terrorists and non-state actors,” the joint statement added.

Rana, a Canadian national of Pakistani origin, is currently lodged at a metropolitan detention centre in Los Angeles. He is known to be associated with Pakistani-American terrorist David Coleman Headley, one of the main conspirators of the 26/11 attacks.

Speaking at the joint press meet, Trump said "Today I am pleased to announce that my administration has approved the extradition of one of the plotters and very evil people of the world, and having to do with the horrific Mumbai terrorist attack, to face justice in India. So, he is going back to India to face justice."


The extradition of Rana was cleared by the US Supreme Court in January as it rejected his review petition in the case.


India last month said it was working with American authorities for the early extradition of Rana.


"The US Supreme Court on January 21 declined to hear a petition from the accused. We are now working with the US side on procedural issues for early extradition to India of the accused in the Mumbai terror attack," External Affairs Ministry spokesperson Randhir Jaiswal had said.


In November 2012, Ajmal Amir Kasab, the lone surviving gunman among the Pakistani group, was hanged to death in Yerawada Jail in Pune.
