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.

Why is Mamata Seeing Ghost of Bangladesh?

Why is Mamata Seeing Ghost of Bangladesh?

Mamata is seeing a ghost of Bangladesh behind the massive outrage and waves of protest over rape and murder of the trainee doctor. And the reasons are many.

It’s been over a fortnight. Yet with each passing day the voice of protest is getting louder and stronger. From the streets of Kolkata it’s pouring into roads of hinterland. The cry for justice for a rape victim has consolidated into a wail of demands to set a lot of wrongdoings right. Here in lies the fear and trepidation. Wasn’t the issue that brought the youth of Bangladesh out on the thoroughfares a simple, innocent one of quota reform?

The chief minister of Bengal, known for understanding the pulse of people better than many, was quick to read the signages floating in the political horizon.

The most obvious reason for her to be tensed is that both the regime change in Bangladesh and the mass protest in Bengal, were student-driven to begin with. The two incidents---end of 15 year old Sheikh Hasina government and turbulence in West Bengal, over the heinous crime, falling back to back, the first on August 5th and the latter from August 9th onwards, give natural scope for comparisons. More so, because in both the cases the movement strayed beyond an affected constituency to include aggrieved people at large, cutting across socio-economic demography. If the quota reform protest started by students in Bangladesh became a mass uprising against an autocratic regime, the campaign demanding justice for the rape victim and overall safety and security of women in Mamata Banerjee’s Bengal soon snowballed into a movement of no-confidence against the government. Slogans--”Mamata must resign” also got floated in social media much in line with the call for ouster of Sheikh Hasina. In fact “Resignation of Hasina” became the single point agenda into which all other fringe demands coalesced.

Incidentally, even before people started drawing parallels, that there could be a thread of commonality in the way the upheaval in Bangladesh and Bengal played out, Mamata was quick to point out that the Opposition were trying to pull off a Bangladesh by politicizing the tragic incident: “A coordinated approach has been executed by the BJP and the CPIM with support from the Centre to defame Bengal and exploit the situation....They want to make a Bangladesh here. They are taking cues from student unrest in Bangladesh and are attempting to capture similarly. I have no longing for the chair. I came here to serve people.”

Not only Mamata, her political lieutenants are consistently equating the turmoil in Bengal with the mayhem in Bangladesh. Cabinet minister for North Bengal development Udayan Guha threatened to take stern action against those, who would be trying to exploit the situation by emulating a Bangladesh like movement. “ Even after the hospital was vandalised, the police did not open fire on anyone. The police will not allow a Bangladesh type situation. We will not allow Bengal to turn into Bangladesh, Guha thundered.

Is the government’s fear unfounded?

Apart from the similarities on ground zero, as to how and where the future course of events are heading to, there are ample reasons for Bengal to mull on-- as to what led to a Bangladesh like boiling point. To begin with, it’ll be appropriate to talk of Bangladesh and the prevailing situation, that made the students’ protest become big in magnitude. The students were out on the streets because of a high reservation in public jobs. Unemployment and stagnant job market in private sector coupled with a high rate of inflation drove the educated youth to rebel against the government.

But soon the students found enormous number of sympathisers, who were equally at the receiving end. According to Bangladesh citizens, the last two terms of the Sheikh Hasina government were a mockery of democracy. Even elections would be compromised. As Hasina grew from strength to strength, she politicized institutions. The rank and file of police owed allegiance to the ruling dispensation. Extortion, harrassment and raids by police and people in power became rampant. An atmosphere of fear and repression reigned and people got restless to overthrow the government.

Politicization of institutions has been happening in Mamata government too. Allegations are quite strong that police in Bengal functions at the beck and call of political bosses. The lapses and alleged loopholes on the part of police in handling the rape and murder of the young doctor have yet again revealed a sense of confused or misplaced loyalty.

But above everything else both Hasina and Mamata governments allegedly seem to have twined in accepting corruption as a way of life. In Bangladesh jobs of primary and secondary teachers got sold at premium, Rs 10-12 lakh in the Hasina regime. Even police had to pay up for prized postings and transfers. In Bengal busting of the teacher’s recruitment scam has revealed how unsuccessful and ineligible candidates got government jobs in schools in exchange of bribes.

Similarities are multiple and inescapable. Mamata has good reasons to be apprehensive. It’s not only she, who can see and connect the dots. People, out on the streets, clamoring for justice, can see a providential pattern somewhere in the unfolding of future events in these two places-- Bangladesh and Bengal. True, they share more than 2,217 odd km of border. They share the same umbilical cord, other than language, culture, ethos, icons. Even emotions are the same. So she cannot take any risk.
