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.

Lateral upgrade to ailing annihilation

Lateral upgrade to ailing annihilation

Being the first person from the private sector to be appointed as chairperson of Securities and Exchange Board of India (SEBI) as part of the government’s lateral initiative, Madhabi Puri Buch also holds the honour of being the first woman to hold the top post as capital market regulator.

But the laurels that the former private sector banker enjoyed in her earlier stint with ICICI Bank, was marred with allegations that she and her husband were having a stake in offshore entities, which were used to artificially inflate shares of Adani group companies.

Terming the allegation as `character assassination, Buch clarified that all disclosures have already been furnished and the fund in question did not invest in any securities involving the Adani group.

When it rains, it pours. This allegation was subsequently followed by Congress Party allegation that Buch had received salary and post-retirement benefits from ICICI Bank after she quit the private sector bank.

In its clarification to the stock exchanges, ICICI Bank asserted that the payments made to Buch were purely retirement benefits after her exit from the bank and they were neither salary nor employee stock options.

Prior to these allegations, Buch tenure at SEBI was all about bringing in quick reforms on operational issues by changing the format of consultation paper to bring in larger responses digitally. Being data savvy, the rationale of her decisions were democratic based on big data analysis derived from the responses received to the consultation papers.

Further she bifurcated the duties of the SEBI staff between operations and enforcement, which were done by the same persons earlier. Having worked for the private sector in the capital market domain space, Buch had a better understanding of the subject compared to officers from the administrative service in the past that reflected even in her orders as a whole-time director at SEBI before becoming the chairperson. As a whole time director at SEBI, her orders on adjudication issues were more directional to the capital market space, according to experts in the compliance space. She was also quick to revamp the old provisions of the 90s at SEBI.

Being tech and data savvy, Buch enhanced regulatory surveillance and detection of market manipulation, insider trading and fraud while also emphasizing on strengthening corporate governance by introducing stricter rules for independent directors and enhancing disclosures for related-party transactions.

To put in perspective, the annual report of the capital market regulator in the just concluded financial year revealed that the number of investigations related to insider trading jumped to 175 in 2023-24 from 85 in the preceding year while probes related to front running jumped over three times to 83 from 24 in the preceding year.

Transparency in mutual funds by implementing measures to protect retail investors along with tightening norms for initial public offers, particularly in the SME platforms were some of her other positive initiatives including confirmation of denial of any market rumours within 24 hours for the top 100 listed companies which will be extended to top 250 companies from December 1. However increased transparency and compliance with tightening regulations led to increased operational costs for the market participants and hence faced resistance from certain quarters. Born in 1966, Buch completed her primary education in Mumbai and graduated with specialization in Mathematics from Delhi and later obtained a management degree from Indian Institute of Management, Ahmedabad. In between, she got engaged to Dhawal Buch, a director at a consumer goods multinational at the age of eighteen and got married at the age of 21.

Besides ICICI Bank, Buch also worked as a lecturer at a college in England, worked at Greater Pacific Capital in Singapore and ICICI Securities as its CEO. She also worked as executive director on several private sector companies and as a consultant for New Development Bank (Brics Bank).

What now remains to be seen, is whether Buch, who survived the 26/11 terror attack when she along with her husband, was attending a meeting at Taj, be able to overcome the current ordeal. Keeping fingers crossed for the times to come.
