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.

Imran Khan’s Fall from Grace

Imran Khan’s Fall from Grace

Imran Khan, once hailed as Pakistan’s most charismatic and resilient leader now finds himself in a position unprecedented for a man of his stature.

The former Prime Minister of Pakistan, once known for his unyielding spirit and fierce determination, now shows signs of strain. Imprisoned and facing numerous charges, Khan appears to be a shadow of the leader who once inspired millions.

Khan’s recent meeting with journalists revealed a man who is a shell of his former self. Once confident and commanding, his body now shows a sense of unease and agitation. Those who met him describe a waning spirit, a stark change for a leader once known for his steadfastness in adversity.

The journalists described Khan as a man who is aware that his political party, Pakistan Tehreek-e-Insaf (PTI), is losing its once-iron grip on the nation’s imagination―a realisation that visibly shook him.

The PTI, once a magnet for massive crowds and inspired loyalty among its supporters, is now struggling. The much-hyped rally scheduled for August 22 in Islamabad, was embarrassingly cancelled due to a lack of public interest. Khan, in a bid to save face, claimed that the rally was called off to avoid potential violence. In a sign of growing desperation, Khan rescheduled the rally for September 8 and directed his party leaders to overcome any obstacles. This defiant stance is typical of Khan’s confrontational style, and his public directives highlight his insecurity about his party’s ability to mobilise support.

While Khan outwardly appears calm and composed, the multiple cases against him and his time in jail have left him isolated and struggling with loneliness. Even in this difficult situation, he remains in the headlines, thanks to his uncanny ability to stay in the public’s eye. Khan recently made headlines by applying for the University of Oxford Chancellorship, a move initially dismissed as a rumor but confirmed by his spokesman, Sayed Zulfikar Bukhari. As an Oxford alumnus, Khan would be the first Asian to take the role. Many see this bid as a strategic play to leverage his international profile against Pakistan’s establishment, a move that has kept him prominently in the media spotlight.

The political landscape in Pakistan is deeply divided. Prime Minister Shahbaz Sharif, in his second term, has failed to address critical issues including unemployment, soaring inflation, and deteriorating law and order. His administration’s inability to deliver on its promises has only deepened the public’s disillusionment, leading to growing nostalgia for Khan’s past leadership.

Shahbaz Sharif’s government is a source of frustration for the Pakistani people and a cause for concern for the country’s military. Historically, the military has shaped Pakistan’s political trajectory, stepping in when civilian governments falter. The military reportedly is growing uneasy about the government’s performance especially Sharif’s inability to stabilize the country and mend relationships with key neighbors, particularly India. Additionally, its deteriorating ties with Afghanistan and Iran have left Pakistan increasingly isolated. Even China, Pakistan’s longstanding ally, has expressed dissatisfaction with the government’s policies, a worrying sign given the importance of the China-Pakistan Economic Corridor (CPEC) to the country’s economic future.

It is within this context of political turmoil and international isolation that Imran Khan remains a potent force. Despite his legal troubles and the challenges facing his party, Khan’s popularity endures. For millions of Pakistanis, his tenure as Prime Minister is seen as a time of relative stability and hope, a stark contrast to the current administration’s ineptitude. This perception has kept Khan’s political base intact, even as his party faces an uphill battle in the coming months.

However, Khan’s ability to navigate the current political landscape is far from guaranteed. The PTI’s diminishing support, coupled with the increasing pressure from the establishment, raises questions about Khan’s long-term strategy. His recent moves, including the application for the Oxford Chancellorship, suggest a leader willing to explore unconventional avenues to maintain his relevance. But whether these tactics will translate into a successful political comeback remains to be seen.

Pakistan’s political future is more uncertain than ever. Imran Khan’s journey from cricketing legend to political maverick has been extraordinary. Still, as he faces the toughest challenge of his career, the question remains: Can he once again defy the odds and reclaim his place at the helm of Pakistani politics, or is this the beginning of the end for a once unstoppable leader?

Khan’s story is a testament to the complexities of power and the unpredictable nature of political life in Pakistan. His rise, driven by charisma, populism, and a genuine desire for change, now faces the realities of personal and political challenges, raising the possibility that his time may be running out.

Imran Khan is a beacon of hope for his supporters, and a polarizing figure for detractors, whose ambitions have often clouded his judgment. As the nation watches, the world is left to wonder: What will Imran Khan’s next move be? And more importantly, what does it mean for the future of Pakistan? The coming months will be critical not only for Imran Khan but for Pakistan as a whole. The decisions made during this period will shape the country’s trajectory for years. Whether Khan emerges victorious or is consigned to the annals of history as a fallen leader, one thing is certain: The story of Imran Khan is far from over.
