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 waits to lasso diamantaire Mehul Choksi

Mumbai: India rubbed its hands gleefully as the Belgium Police honoured its request to arrest the absconder diamantaire Mehul Chinubhai Choksi – more than seven years after he, along with his nephew Nirav Deepak Modi - allegedly duped the Punjab National Bank of nearly Rs. 13,800-crores.

 

The scam involving the ‘Mehul Mama-Nirav Bhanja’ erupted in Jan 2018, after the PNB lodged a complaint with the Central Bureau of Investigation (CBI).

 

By then the kin, along with many of their family members, winked and slipped out of the country, leaving a rattled India rubbing its palms in disappointment.

 

A political-cum-financial storm raged, embarrassing the Bharatiya Janata Party government of Prime Minister Narendra Modi a year before the Lok Sabha elections.

 

Multiple agencies launched a multi-pronged probe into what became the biggest banking scam in the past quarter century – and almost four times bigger than the stock market-cum-banking fraud the late Big Bull Harshad Mehta had inflicted on the Indian economy 33 years ago (in April 1992) – when it was just opening up.

 

In Belgium

According to official reports, Choksi was living with his Belgium citizen-wife Preeti in Antwerp, a global diamond hub, presumably for the past 18 months on a ‘residency permit’ acquired through questionable means, for medical reasons.

 

Earlier, he shot to the headers (June 2021) while being taken in a wheelchair to a court by the Dominican Republic's Police on charges of sneaking into the small country in the Caribbean Sea, North America.

 

Interestingly, as the Antigua & Barbuda government initiated the process to cancel his citizenship acquired through an investor visa, Choksi had suddenly gone ‘missing’ till he surfaced in the Dominican Republic.

 

The April 2025 action by Belgium followed a request by India’s CBI and the financial frauds specialist Enforcement Directorate (ED) to nab Choksi as the InterPol had revoked his Red Corner Notice in 2023.

 

Mama and Bhanja

‘Mama’ Choksi is the founder-owner of Gitanjali Group while ‘bhanja’ Nirav’s Firestar plus other companies – and the duo, with some PNB officials hand-in-glove – conspired to make a ‘mamu’ of not only PNB, but other banks, as it subsequently tumbled out.

 

After making a quiet exit, Choksi was detected living in the verdant Antigua & Barbuda Isles (West Indies), then attempted entry to the Dominican Republic, was sent back to Antigua & Barbuda and then went to Belgium where he was nabbed on Sunday.

 

Similarly, Modi was found sauntering on the streets of London and nabbed in March 2019. He remains in jail there since India's extradition is still pending.

 

However, India is keeping its fingers crossed that it may finally lay hands on Choksi, bring him to India and face trial in the PNB scam, though it may take time.

 

Born in Mumbai (1959) and educated in Gujarat, Choksi, 66, and wife Preeti have three children.

 

The Rs. 13,800-crore PNB scam

In the modus operandi revealed after India’s second-largest PSU bank PNB admitted it was scammed, Choksi and Modi used fraudulent Letters of Undertaking (LoU) to get overseas credits or loans from Indian banks.

 

The PNB first informed the Reserve Bank of India (RBI) of the fraud and then lodged a criminal complaint with the CBI in Jan. 2018, plus another CBI complaint in Feb, that led to a FIR against Modi and Choksi and their companies.

 

The ED entered the scene to probe the allegations of money-laundering through the LoUs – which they allegedly misused to avail short-term business finances from foreign branches of Indian banks.

 

The probe said that the duo were availing the LoUs from the PNB’s Brady House Branch from March 2011, and over the next six-seven years, managed to get a whopping 1,200-plus LoUs like a breeze with the help of some friendly bankers within.

 

Post-scam, the gold-diamond companies Gitanjali Group and Firestone Group with multiple operations in India and abroad have largely wound up, while some personal assets of the mama-bhanja have been auctioned to recover a part of the dues.

 

ED's plea to declare Choksi fugitive stuck for seven years

Even as absconding diamantaire Mehul Choksi, a key accused in the Punjab National Bank loan fraud case, has been arrested in Belgium, the ED's plea to declare him a fugitive economic offender has been pending before a court in Mumbai for nearly seven years.


Choksi, 65, and his nephew diamantaire Nirav Modi are the prime accused in the Rs 13,000 crore PNB bank loan fraud case. Choksi was arrested in Belgium following an extradition request by Indian probe agencies, official sources said on Monday.


The Enforcement Directorate had filed the application in July 2018, seeking to declare Choksi an FEO and confiscate his assets under provisions of the Fugitive Economic Offenders Act.


However, the matter has witnessed repeated delays owing to a barrage of applications filed by the accused in the PMLA court and the Bombay High Court alleging procedural lapses in the Enforcement Directorate's plea.


"The court is kept busy with frivolous applications, and hearing on our application to declare him (Choksi) an FEO has been adjourned for the past seven years,” an ED officer had said after the hearing was once again deferred this February.


"The court should have continued the hearing and taken a decision on the future course of action once the application was moved," the officer had said.

He had urged the court to take note of the repeated filing of similar applications and to not entertain them.


Choksi's lawyer had informed the court that the accused was undergoing treatment for suspected cancer in Belgium and intended to file an application in connection with his health.


Under the FEO Act, an individual can be declared a Fugitive Economic Offender if a warrant has been issued against him for an offence involving Rs 100 crore or more and he has left India while refusing to return. Once declared an FEO, the person's property can be confiscated by the investigating agency.


Choksi had challenged the ED's application in the Bombay High Court, alleging that the agency "had not followed proper procedure before filing the application and, hence, it stands vitiated".


However, in September 2023, the High Court dismissed his plea, ruling that the ED had adhered to the prescribed format under the FEO Act. It also vacated a stay on the special court's proceedings.


Despite this, the hearing on declaring Choksi FEO could not commence, with Choksi continuing to file applications before the special court through his lawyers.


While most of these pleas have been dismissed, a few remain pending. His latest attempt to stall proceedings through a plea to recall the notice issued on the ED's FEO application was rejected in December 2023.


According to ED officials, Choksi left India under suspicious circumstances in early January 2018.


Shifting stance

Choksi's counsel has argued that the ED kept shifting its stance on the material grounds for declaring him an FEO and that the suspension of his Indian passport made it impossible for him to return for investigation.

The court, however, rejected this argument, stating that the notice was issued based on accurate information and not based on "wrong facts or mistaken assumptions".


ED claimed the accused left the country under suspicious circumstances in the first week of January 2018.


Nirav Modi has already been declared as an FEO by the special court. He has been lodged in jail in London since 2019.
