Tamil Nadu has spoken, and it has spoken loudly.
On May 4, 2026, the results of the Tamil Nadu Legislative Assembly elections delivered a verdict that no pollster fully predicted and that no dynasty could have anticipated. The new party Tamilaga Vettri Kazhagam (TVK), founded by Tamil actor Vijay, emerged as the single largest party in its first-ever election, ending a 59-year streak of dominance of Dravidian parties in the state, a seismic political shift by any measure. The election recorded the highest voter turnout in the state's history, at 85.1%. The people of Tamil Nadu have placed an extraordinary trust in a new hand at the wheel.
At Planet Watch, we welcome this change, not because we endorse any political party, but because political renewal carries within it the possibility of institutional renewal. The environmental crises stacking up across Tamil Nadu have persisted, in part, because they were politically convenient to ignore. A new government without inherited relationships with polluters, mining mafias, or industrial lobbies has a rare window of opportunity: to build a different kind of Tamil Nadu. One that grows. One that breathes. One that does not choose between its rivers and its factories, but demands that both can coexist.
This article is our message to that government. It is also a record of what has gone wrong, and what must be fixed.
WHAT THE TVK MANIFESTO SAYS, AND WHAT IT DOESN'T
Before we list the environmental agenda we urge the new government to adopt, we must be honest about where the TVK manifesto stands on these issues.
The TVK released its election manifesto on April 16, 2026. Among the key promises are a monthly assistance of Rs 2,500 for homemakers, 200 units of free electricity per household, and six free LPG cylinders annually. For farmers, the manifesto includes annual investment assistance of Rs 15,000 for land-owning farmers, crop loan waivers, Minimum Support Price (MSP) of Rs 3,000 per quintal of paddy, and 5 lakh solar pumps. Fishermen have been promised Rs 27,000 during the lean season, a minimum support price for fish, and accident insurance coverage of Rs 25 lakh. These are important commitments to communities whose livelihoods are on the frontlines of environmental damage.
The manifesto speaks of transparent governance, development, and people-first leadership. These are necessary conditions.
But here is what the TVK manifesto, as reported across credible sources, is largely silent on: sand mining policy, industrial pollution enforcement, forest fire preparedness, river restoration, plastic waste management, the NLC lignite expansion, the SIPCOT industrial complex in Cuddalore, illegal quarrying in southern Tamil Nadu, and a dedicated environmental protection framework for the incoming government.
This silence is not unique to TVK. Virtually every Tamil Nadu election manifesto has treated the environment as a footnote. But the new government carries the moral weight of a fresh mandate. The people who turned out in record numbers were not voting only for gold and gas cylinders. They were voting for a future. That future is impossible without a liveable environment.
The solar pump promise for farmers is encouraging: 5 lakh solar pumps represent a meaningful reduction in fossil-fuel-dependent irrigation and, if well-targeted, a genuine step toward sustainable agriculture. The fishermen's welfare promises are a nod to communities ravaged by coastal pollution and sea boundary destruction. These are hooks that environmental governance can build on.
But hooks are not a policy. We urge the new government to develop one, urgently, and in consultation with communities.
TAMIL NADU'S ENVIRONMENTAL CRISIS: THE INHERITANCE
The TVK government does not inherit a clean slate. It inherits a state under compounding ecological stress. Here is the honest inventory:
Rivers in Distress
Tamil Nadu's rivers are dying by degrees. The Cauvery, the Palar, the Vaigai, the Thamirabarani, the Vellar, and the Uppanar have all suffered severe degradation from a combination of industrial effluent discharge, sewage inflows, sand extraction, and reduced rainfall. The Palar, once the lifeline of the tannery belt in Vellore, has sections with no natural flow at all, its groundwater poisoned by decades of chromium discharge from tanneries. The Uppanar in Cuddalore, which runs parallel to the coast, carries industrial effluents from the SIPCOT industrial complex into the Bay of Bengal, with average TDS levels documented at 28,870 mg/l, among the most extreme contamination measurements in coastal India.
River restoration cannot happen without confronting the industries and political interests that benefit from keeping rivers unprotected. The new government must enact a River Protection and Restoration Policy for Tamil Nadu, with legally enforceable riparian buffer zones, mandatory real-time effluent monitoring, and criminal liability for industrial discharge violations.
Air That Burns: The SIPCOT Industrial Crisis in Cuddalore
Some of the dirtiest industries, including chemical factories, petrochemical refineries, shipbuilding yards, textile dyeing units, and coal-fired power plants, have made a beeline for Cuddalore. The Tamil Nadu government has historically earmarked Cuddalore district for locating polluting industries, with the argument that Cuddalore is already polluted, so let us concentrate all polluting industries here.
Let that argument sink in. The government chose to sacrifice an entire district and its people, its fishing communities, its farmers, and its children, based on the logic of contamination efficiency. This is environmental injustice made official policy.
A NEERI study on volatile organic compounds in the SIPCOT estate found 94 chemicals in the air, including 15 hazardous air pollutants. The level of benzene, a chemical that causes blood cancer in children, is 125 times above safe levels, while other carcinogens like chloroform, carbon tetrachloride, methylene chloride, and trichloroethylene are 881, 553, 32.5, and 21.8 times higher than acceptable levels. Residents of Eachangadu and surrounding villages are living in a slow-motion Bhopal. Children do not know what clean air smells like. Women report menstrual irregularities and delayed puberty in girls. The air around the estate has at least 36 documented odours, each a marker of a different toxic release.
Threshold limits have not been set up for 19 stack parameters for industries falling under the Red category in the Cuddalore SIPCOT complex, meaning the very monitoring system designed to catch excess emissions is blind to them. Two Continuous Ambient Air Quality Monitoring Stations (CAAQMS) set up in Cuddalore have been reported as dysfunctional for over a year.
The new government must commit, from Day One, to making Cuddalore's air breathable again. This means: immediately operationalising the CAAQMS stations; setting threshold limits for all 19 unregulated stack parameters; conducting an independent epidemiological health survey in the SIPCOT-adjacent villages; and publishing the NEERI findings, suppressed for years, in the public domain.
The SIPCOT Expansion Proposals: They Must Be Dropped
PMK founder S. Ramadoss has urged the Tamil Nadu government and the Pollution Control Board not to grant permission for the proposed expansion projects of the Chemplast Sanmar company at the SIPCOT industrial complex in Cuddalore, noting that the SIPCOT industrial estate in Cuddalore, functioning since 1971, houses several red-category industries handling hazardous substances such as pesticides, paints, dyes, pharmaceuticals, chemicals and PVC, industries that have severely affected residents of more than 50 surrounding villages.
We stand unreservedly with this demand. The Cuddalore SIPCOT estate is not a zone awaiting development. It is a zone already in crisis. Expanding industrial capacity before the existing violations are remediated, before the health burden on surrounding communities is addressed, and before a credible pollution-reduction plan is in place, is not development. It is the further mortgaging of a community's health for industrial profit.
The proposed SIPCOT expansion in Cuddalore must be dropped. Instead, the government must initiate a Cuddalore Industrial Remediation Plan, a time-bound, publicly monitored programme to bring existing SIPCOT industries into compliance with air and water quality norms, with relocation assistance and health compensation for affected families.
The Proposed New Leather Factory: A Red Line
Tamil Nadu is already home to approximately 600 tanneries, about 45% of all tanneries in India, concentrated in the Vellore belt, which has already paid an enormous ecological price. The Palar River, which runs through this belt, has been devastated by chromium-VI discharge, sulfide effluents, and saline wastewater from the tanning process. Production of one tonne of raw leather requires between 15,000 to 40,000 litres of water and generates waste streams containing carcinogenic chromium compounds, hydrogen sulfide, and biological oxygen-demand loads that overwhelm any treatment infrastructure in proximity.
Reports of a proposed new large-scale leather factory establishment in Tamil Nadu, in a region that has not hosted such facilities, raise serious alarm for Planet Watch. The chromium-laden tannery effluent story in Vellore took decades to become visible. A new facility, in a new district, without a proven zero-liquid-discharge track record and a fully operational common effluent treatment plant already in place, risks importing that story to communities that have not yet been harmed.
The new government should not grant environmental clearance for any new large leather manufacturing facility unless it meets the following non-negotiable conditions: Zero Liquid Discharge certification verified by an independent authority; chromium-VI monitoring real-time and publicly available; proximity exclusion zones of at least 3 km from any residential settlement, agricultural land, or water body; and community consent from the affected gram panchayats under the Forest Rights Act and Environmental Impact Assessment framework.
Development is important. The leather sector generates employment and foreign exchange. We do not dismiss those realities. But we reject the framing that community health is the price of industry. That trade-off is not development. It is exploitation with a subsidy.
The NLC Lignite Expansion: Cuddalore's Coal Burden Must End
The Neyveli Lignite Corporation (NLC) has operated in Cuddalore since 1956. It has taken land from farmers, over 65,000 acres acquired over the decades, with promises of employment that were systematically diluted into contractual labour at minimal wages. It has depleted the water table, left agricultural land as rubble mounds, and generated ash and lignite dust that coats surrounding villages. And yet the expansion drive continues.
According to environmental activists, the NLC is in the process of acquiring around 90,000 acres of land for its coal and lignite plants. Cuddalore has already been earmarked as a mining-polluted district and further mining of coal will create major difficulties for the people of the area. PMK state president Anbumani Ramadoss has pointed out that Tamil Nadu produces around 32,000 MW of power per month, of which the requirement is only 18,000 MW, and asked, in this context, what justifies further NLC expansion.
From January 2023 onwards, community members have been giving calls for rounds of protests after NLC India's plan was formulated for acquiring 25,000 acres of land for the expansion of Mine III, in the villages of Karivetti, Karaimedu, Kathazhai, Mummudi Cholagan, Melvalaiyamadevi, and Keezhvalaiyamadevi. These are not protest communities against progress. They are farmers defending their last remaining agricultural land in a district already crushed under industrial weight.
India has committed to achieving 60% non-fossil power capacity by 2035. The NDC 3.0, approved in March 2026, makes lignite expansion a strategic anachronism, not just an environmental harm but a policy contradiction. Expanding lignite extraction in Tamil Nadu in 2026 is building infrastructure for a fuel the world is moving away from, on land taken from farmers, in a district already dying from its industrial legacy.
Planet Watch calls on the TVK government to formally oppose NLC Mine III expansion and to initiate dialogue with the Central government on transitioning the NLC Neyveli complex toward renewable energy dominance through solar, wind, and green hydrogen, using its existing land, infrastructure, and workforce as the foundation. Neyveli's people deserve a just transition, not another generation of lignite dust.
THE ILLEGAL QUARRY CRISIS IN SOUTHERN TAMIL NADU
The hills of southern Tamil Nadu, in Tirunelveli, Tenkasi, Kanyakumari, Virudhunagar, Thoothukudi, and the Kongu belt, are being dismantled, quarry by quarry, with minimal regulatory accountability.
PMK's Anbumani Ramadoss has stated that hills are being broken down in southern districts and the Kongu region, and the minerals are being smuggled to Kerala, while illegal mining of river sand is going on unabated simultaneously across the state.
Illegal quarrying is not merely an environmental crime. It is a geological crime: the permanent destruction of landforms that took millions of years to form, that anchor rainfall patterns, that replenish aquifers, and that protect valley communities from flooding. When a hill in Tirunelveli is quarried illegally, the debris enters streams, the dust enters lungs, and the emptied hilltop becomes a rain shadow that contributes to the drought of the next generation.
The scale is staggering. Though Tamil Nadu's Public Works Department figures suggest 5,500 to 6,000 truck loads of sand are mined daily, in reality this figure is estimated to be around 55,000 truckloads per day. In 2013, illegal sand mining in the state was estimated to be worth Rs 15,000 crore, resulting in the state exchequer losing over Rs 19,800 crore in revenue. These numbers have only grown since.
The rivers bear the most direct injury. The Palar, Vaigai, Cauvery, and Thamirabarani river basins are some of the most affected regions, with illegal quarrying happening in these areas in broad daylight. Every load of river sand extracted is a section of riverbed geology removed, permanently lowering the water table, deepening the channel, and accelerating bank erosion. Bridges, irrigation structures, and drinking water wells near sand-mined rivers are being undermined, literally.
The TVK government must, as a first-year priority:
· Conduct a satellite-mapped audit of all active and recently active quarries in southern Tamil Nadu and the Kongu belt, cross-referencing with valid lease records
· Establish a Special Task Force with police, revenue, and forest department coordination to dismantle illegal quarry operations, with prosecutions under the Mines and Minerals (Development and Regulation) Act and the Environment (Protection) Act
· Promote M-sand (manufactured sand) as the standard for all government construction contracts, removing the economic incentive for river sand extraction
· Declare the Thamirabarani, Vaigai, and Cauvery riverbeds as ecologically protected zones with sand extraction moratoriums in critical sections
STOP KERALA'S WASTE DUMPING ACROSS THE TAMIL NADU BORDER
It is an open secret along the Kerala-Tamil Nadu border that Kerala has, for years, used Tamil Nadu's border districts as a disposal ground for waste that cannot be legally processed within Kerala's own municipalities. Solid waste, construction debris, and in some reported cases municipal sludge, have been dumped in forested and semi-forested border areas in districts including Coimbatore, Nilgiris, and Tirunelveli.
This is not a bilateral hospitality. It is an environmental rights violation. Tamil Nadu's communities living near those dumping sites bear the health burden: contaminated streams, vermin proliferation, soil poisoning, and the slow encroachment of waste into protected forest zones. The previous government raised this intermittently but without sustained diplomatic or legal force.
The new government must write a formal letter of diplomatic notice to the Kerala government, supported by district-level geo-tagged evidence of cross-border dumping incidents, and simultaneously invoke provisions under the Solid Waste Management Rules, 2016 and the Environment (Protection) Act, 1986 to prosecute transporters and commission agents involved in organised cross-border waste movement. If Kerala's own waste management infrastructure is inadequate, that is a problem for the Kerala government to solve, not for Tamil Nadu's forests and rivers to absorb.
PREPARE NOW FOR FOREST FIRES: THIS IS AN EL NINO YEAR
This is not a warning to be taken lightly.
NOAA's May 2026 ENSO advisory has confirmed a 61% probability that El Nino conditions will emerge between May and July 2026 and persist through the year. El Nino years systematically reduce monsoon rainfall across peninsular India, raise pre-monsoon temperatures, and create precisely the conditions under which forest fires escalate from isolated incidents to catastrophic, weeks-long events.
Tamil Nadu's Western Ghats, including the Nilgiris, Anamalai, Palani, and Meghamalai ranges, are among the most biodiverse forest systems in the world, home to endemic species found nowhere else. They are also becoming increasingly fire-prone. The Nilgiris has seen devastating fires in recent years. Invasive grasses like Lantana camara and Senna spectabilis, which grow in dense, highly flammable thickets, have spread across thousands of hectares of Ghats forest, creating tinderboxes that native vegetation never was.
The reservoir data from the Central Water Commission (April 30, 2026) confirms that Tamil Nadu's reservoirs are already below normal levels, with pre-monsoon water stress mounting. If El Nino delivers a delayed or deficient southwest monsoon this year, the forests enter the critical July-September window dangerously dry.
The new government must, before June 2026:
· Activate Forest Fire Prevention and Response Protocols across all Ghats districts: Nilgiris, Coimbatore, Dindigul, Theni, and Tirunelveli
· Deploy fire-watch personnel in high-risk zones identified by the Forest Survey of India and the Tamil Nadu Forest Department's fire vulnerability mapping
· Mobilise local tribal and forest-dwelling communities, whose knowledge of fire behaviour in specific landscape types is unmatched, as the first line of detection and response
· Procure adequate firefighting equipment and communication infrastructure, and establish clear inter-district coordination protocols
· Begin an emergency programme of Lantana camara removal in high-risk, fire-prone areas, prioritising corridors used by elephants and other megafauna
· Coordinate with Karnataka and Kerala counterparts on trans-boundary fire risk management under the Western Ghats interstate framework
· A forest fire in a drought year, in an El Niño season, in the Western Ghats, is not a natural disaster. It is a governance failure waiting to happen. The new government has weeks, not months, to prepare.
THE CUDDALORE COMPACT: A SPECIAL AGENDA FOR A BURDENED DISTRICT
Cuddalore deserves special mention and special attention. It is perhaps the most ecologically exploited district in Tamil Nadu, carrying the combined burden of the SIPCOT chemical complex, the NLC lignite operations, coastal erosion, the Uppanar River's industrial contamination, and the lingering toxicity of the 2004 tsunami's aftermath on coastal geomorphology.
Cuddalore is also a district of extraordinary natural wealth: white-sand beaches, dense mangrove systems, the Pichavaram mangrove forest (one of Asia's largest mangrove ecosystems), cashew groves, fertile delta agriculture, and a rich artisanal fishing tradition going back centuries. It is a district that could be a model of ecological sustainability if it were not being systematically sacrificed for industrial convenience.
Planet Watch calls on the new government to establish a Cuddalore Environmental Crisis Response Committee, a permanent, multi-departmental, community-inclusive body with the following mandate:
· Operationalize all CAAQMS stations and publish air quality data publicly in real time
· Complete the long-pending epidemiological health survey of SIPCOT-adjacent villages
·Implement a phased resettlement and compensation programme for the most affected communities in Eachangadu, Kudikadu, Semmankuppam, and Pachaiyankuppam
· Reject all SIPCOT expansion proposals pending full compliance by existing industries
· Commission an independent Uppanar River restoration study
· Protect and expand the Pichavaram mangrove system as a legally designated Ecologically Sensitive Area
· Oppose NLC Mine III expansion through formal representations to the Central government
THE PHILOSOPHY WE ADVOCATE
Let us be clear about where PlanetWatch stands.
We are not anti-development. Tamil Nadu needs jobs, infrastructure, investment, and industrial growth. Millions of families depend on the economic engine that industrial and commercial activity provides. Fishermen need harbors. Farmers need irrigation. Workers need factories. These are not luxuries. They are survival necessities, and we respect them as such.
But development that poisons a community's water, makes their children's air toxic, mines their rivers into empty troughs, and hands their forests to a fire every summer is not development. It is a delayed catastrophe with a ribbon on it.
Sustainable development is not a compromise between growth and ecology. It is the only kind of growth that does not eventually collapse. A factory that poisons its surrounding village is a factory that will face shutdowns, health compensation claims, legal battles, and workforce illness. A river that is mined into depletion is a river that can no longer support the agriculture that feeds the industries that employ the workers. The ecology and the economy are not opponents. They are the same system.
The TVK government has come to power on a wave of hope. Hope is not a plan. But hope, in the hands of a government willing to govern with courage, is the beginning of one.
Tamil Nadu is watching. Its rivers are watching. Its forests are watching. And so are we.
