How these women are putting forgotten foods back on our plates

Bichu booti, Sana Hua Nimbu, Seema Chintha Daal, Meetha Karela are some of the many regional wild foods and microgreens that evoke childhood memories of love, sharing and the joy of eating together. But as green spaces shrink in cities, food has been reduced to what’s available in the market. Wild edibles, traditional berries and forest fruits have largely vanished from urban Indian plates. “Biodiversity was once an integral part of everyday Indian meals, but it’s gradually disappearing,” says Vibha Varshney, head of biodiversity and food at the New Delhi-based think-tank Centre for Science and Environment (CSE). However, a clutch of Indian women are working to bring these forgotten foods back into our daily diets. They were part of the launch of ‘My Food Story’, a digital platform by CSE that celebrates traditional knowledge, forgotten ingredients, recipes and the powerful stories they carry. Uttarakhand-based food writer Megha Prakash shares how you can’t actively look for these ingredients—you just chance upon them while visiting a house or a market or in conversations with locals. She recalls a vegetable called Meetha Karela found in the hills, which isn’t a bitter gourd but tastes like cucumber. Or an Indian pokeweed, which is poisonous unless cooked from its tender young leaves. Goa-based Anumitra Ghosh Dastidar, chef and restaurateur behind Edible Archives, Bento Bento, and Yo Colombo, talks about how she changes her menu with the seasons, introducing traditional produce that often isn’t cultivated but foraged. “There’s a need to build a network of people who can collect these ingredients regularly,” she says. Ghosh Dastidar has built a team of 5-6 local women who are the backbone of her initiative. She uses ingredients like amade—a sweet-sour fruit commonly found in Goa—and even taro leaves and stems in her recipes. “It’s important to have these on restaurant menus because that’s what inspires people to try them at home,” she says, emphasising the role chefs can play in bringing back indigenous ingredients. Devi Lakshmikutty, co-founder of BioBasics, an online organic brand from Coimbatore, speaks about the critical role social media has played in creating curiosity and awareness about these foods. But she cautions that it shouldn’t be a one-time experiment. “People must cook these foods regularly,” she says. “There has to be a consistent effort to include them in daily diets—only then will farmers continue to grow them.” As Lakshmikutty puts it, “It’s good for us, good for the farmers, and good for the environment.” For nutrition and culinary consultant Sangeeta Khanna, the joy lies in finding and cooking wild foods. She warns that as urban consumers get more used to artificial flavours, it becomes harder to enjoy simpler recipes. “Our palate is no longer used to food in its elemental form,” she says. Khanna’s solution: start by incorporating these ingredients into familiar recipes to make them more acceptable. She highlights that these wild leaves, flowers and berries carry distinct nutritional profiles—packed with micronutrients and macronutrients that cultivated foods often lack. These help enrich gut microbiome and promote gut biodiversity within our bodies. However, Khanna also warns against harvesting from polluted lands or water sources, especially those contaminated with heavy metals.

Indian mega cities face high ozone pollution this summer: CSE

Major Indian cities are grappling with high levels of ground‑level ozone this summer, according to the Centre for Science and Environment (CSE). Bengaluru, Mumbai, Kolkata, Hyderabad, and Chennai recorded multiple days where ozone levels crossed the safe limit. Bengaluru led the rise. The city saw a 29 percent jump in days exceeding the ozone standard compared to last year. “The trend is worrying,” said Anumita Roychowdhury, Executive Director at CSE. “Ozone is a toxic gas and even short‑term exposure can trigger serious respiratory issues.” Ozone is not directly emitted. It forms through chemical reactions involving nitrogen oxides, volatile organic compounds, and carbon monoxide. Sunlight drives this reaction, making summer particularly vulnerable. Unlike pollutants such as PM2.5 or nitrogen dioxide, ozone forms through reactions in the atmosphere. Vehicles, power plants, factories, and other combustion sources emit the gases that trigger ozone. VOCs, one of the key components, also come from natural sources like plants. Once formed, ozone can travel far, affecting both cities and rural areas. “Ground-level ozone can hurt crop yields and threaten food security,” Roychowdhury said. CSE’s analysis used real‑time data from 80 monitoring stations across the five cities. Each station’s data was evaluated for the number of days when eight‑hour average ozone levels breached national standards. The data came from the Central Pollution Control Board’s public platform. The study covered March to May from 2022 to 2025. It used the US Environmental Protection Agency’s method—measuring the highest eight-hour average each day from each station. If even one station exceeded the limit, it counted as a breach for the city. “Ozone build‑up is highly localised and influenced by temperature, wind, and precursor gases,” explained Sharanjeet Kaur, Deputy Programme Manager at CSE. “One or two stations exceeding the limit signals local hotspots that need immediate attention.” She added that average city-level data hides these spikes. “One part of a city might show high ozone while another doesn’t. Averaging hides the risk,” Kaur said. CSE warned that high ozone levels damage the lungs. It inflames airways, worsens asthma, and increases the risk of infections. Children, older adults, and people with existing respiratory conditions face the greatest risk. “Ozone attacks the lungs,” said Roychowdhury. “It increases asthma attacks and hospital visits.” Experts note that ozone and nitrogen dioxide interact in complex ways. Traffic-heavy areas with more NO₂ can suppress ozone, while cleaner zones allow it to build up and persist. “We can’t ignore ozone anymore,” said Roychowdhury. “It’s not just a summer problem. Warmer regions now face year‑round risk.” She added that developed countries saw a rise in ozone after reducing particulate matter without cutting nitrogen oxide emissions. India could face the same pattern. “This is a growing public health hazard,” said Kaur. “Without better monitoring and focused action, we risk long‑term damage to people and the environment.” CSE called for immediate action across all combustion sources—vehicles, industries, waste burning, and household fuels. It also urged the government to include ozone in clean air action plans and emergency systems. “Ozone pollution is not a future threat,” said Roychowdhury. “It’s already here.”

Explained: Centre's U-turn on installing anti-pollution systems in thermal power plants

The central government this week overturned a decade-old mandate to install flue gas desulphurisation (FGD) systems in thermal power plants. From now on, only about 11 percent of India’s 600 thermal power plant (TPP) units have to mandatorily install FGD systems, which are pollution control devices designed to remove sulphur dioxide (SO₂) from the flue gas produced during the combustion of coal in TPPs. The 11 percent of the plants are the ones located within a 10 km radius of the National Capital Region or are cities with a population of at least a million, as per the 2011 Census. For such plants, the government in its latest decision has extended the FGD installation deadline to December 30, 2027, from 2017. The latest decision is also expected to cut electricity costs by 25–30 paise per unit, according to a section of the industry, as 78 percent of the coal-fired power plants, including private ones, will not have to install the FGD systems, the cost of which ranges between Rs 50 lakh per megawatt, as per state-run NTPC, and Rs 1.2 crore per megawatt, as per private players. The relaxation in the norms comes at a time when India is rushing to add 90 gigawatts (GW) of coal-fired power generation capacity in the coming six years to meet the country's growing energy needs. India's peak power demand is projected to touch 458 GW by 2032, and to meet that, the country plans to increase its overall power generation capacity to 900 GW from the current 476 GW. Air pollution had become a severe public health crisis in India by 2015, with major cities like Delhi, Mumbai, Kolkata, and Bengaluru experiencing dangerously high levels of fine particulate matter (PM2.5) and other pollutants. This was largely due to emissions from vehicles, industrial processes, and power plants, particularly coal-fired TPPs. Besides, in 2015, India had just participated in the Paris Agreement under the UN Framework Convention on Climate Change (UNFCCC). As part of its climate action goals, India committed to reducing carbon intensity and increasing its reliance on renewable energy. To tackle air pollution and reduce carbon intensity, the Union environment ministry and the Central Pollution Control Board (CPCB) identified flue gas from thermal power plants as one of the target areas. Flue gas is the mixture of gases such as carbon dioxide, sulphur dioxide, nitrogen oxides, and carbon monoxide that is produced as a byproduct of combustion in power plants or any industrial process that burns fuel. Back then, the government, based on an IIT Kanpur report, stated that sulphur dioxide (SO₂), a byproduct of coal combustion in power plants, was a significant contributor to air pollution, leading to smog and health problems. Hence, the Union environment ministry decided to mandate all existing thermal power plants as well as upcoming ones to get FGD systems installed. The Ministry of Power, NTPC and independent power producers had all urged the environment ministry to impose the mandate in a phased manner by either asking the old plants due for repair and maintenance to be taken up first or ruling it for upcoming plants. However, the environment ministry, backed by orders from the Supreme Court, refused to budge. NTPC Ltd ended up being the only power producer which installed FGD systems in about 11 percent of its power plants, which cost it about $4 billion, or Rs 50 lakh, per megawatt. "SO₂ levels in the plants which do not have FGD range from 800-1200 micrograms per cubic metre, and units which have FGD, the levels are coming between 20-25 (µg/m³). But there's not much impact in PM2.5 and PM10. In fact, we have seen that the desulphurisation process also releases some PM2.5. We had opposed the move since the beginning, but NTPC was compelled to comply as we had to submit an affidavit in the Supreme Court," said a senior NTPC official requesting anonymity. Private players such as Adani Power, JSW Energy and Tata Power continued to wait and watch and did not install FGD systems, saying that implementing it would result in a rise in cost of electricity to the end consumer. Why is the govt exempting thermal power plants now? Justifying its reversal of the mandate, the environment ministry on July 14 said the decision was a “scientifically justified shift towards more targeted, cost-effective and climate-coherent regulation.” “Current exposure levels provide no credible evidence to suggest that SO₂, under prevailing ambient conditions, is a major public health concern. Moreover, sulfate aerosols formed from SO₂ constitute a relatively small fraction of PM2.5,” the Ministry of Environment and Climate Change said in a statement. A detailed analysis carried out by IIT Delhi shows that sulfate contributes only 0.96 percent to 5.21 percent of PM2.5 and 0.57 percent to 3.67 percent of PM10 in cities near TPPs, it added. The government said that the new notification is “based on extensive consultations with stakeholders and research institutions” regarding the effectiveness and rationale behind stack emission standards for SO₂ on 537 TPPs throughout the country, and its role in overall ambient air pollution of the region. This time the government mentioned that the latest decision was based on research studies by IIT Delhi, the National Institute of Advanced Studies, as well as by the National Environmental Engineering Research Institute (NEERI) — a constituent laboratory of the Council of Scientific and Industrial Research (CSIR), besides scientific examination by the Central Pollution Control Board. Dilution of anti-pollution measures? According to Shreya Verma, programme manager, Centre for Science and Environment (CSE), the new SO₂ norms fall short of India’s clean air commitment. "Nearly a decade after SO₂ limits were first notified in 2015, MoEF&CC’s revised rules also leave Category B plants to case-by-case discretion — effectively mandating SO₂ norms for only 11 percent of capacity (Category A). This weakens regulatory intent, delays pollution control, and poses a risk to public health. SO₂ is a major contributor to PM2.5 — we cannot afford diluted action. India needs strong, uniform standards to meet its clean air goals," she said. The notification states that Category B – located within a 10 km radius of critically polluted areas (CPA) or non-attainment cities (NAC) – may or may not have to install FGD. This would depend upon a decision by a committee of experts (Expert Appraisal Committee) – an existing body constituted by the environment ministry that grants environment clearances to proposed TPP projects.

SO2 emission not a ‘major public health concern’—environment ministry defends revised norms after flak

The Centre has defended its decision to push the sulphur emission norms compliance for thermal power plants to 2027, saying that it is based on “extensive consultations” and “scientific studies.” The notification, released Friday, postponed the compliance date for thermal power plants to install sulphur dioxide (SO2) emissions for the sixth time after the order was first passed in 2015. This time, the Union Ministry of Environment, Forest and Climate Change (MoEFCC) also exempted 78 percent of the 537 existing thermal power plants from having to install the SO2 emissions regulation machinery at all. Under the new regulations, only Category A power plants, which are 9 percent of total power plants—which are within 10 km of NCR or cities with million-plus populations—are mandated to install flue-gas desulphurisation systems (FGDs). For the Category B power plants, the FGD installations will be on a case-by-case basis, while Category C facilities, which make up 462 plants in total, have been fully exempted from installing these systems. Despite the measure first being introduced in 2015, only 39 power plants in India have installed the FGDs as of 1 August 2024. “Exempting a large number of thermal power plants—around 78 percent—and mandating emission controls on only 11 percent of India’s total thermal power capacity falls far short of supporting the country’s clean air goals,” said Shreya Verma, programme manager of industrial pollution programme at Centre for Science and Environment (CSE). According to an MoEFCC note released Monday, the decision to exempt certain power plants from installing FGDs was taken after examining sulphur emissions from TPPs, air quality data from near TPPs, and the cost of installing FGDs. It said the total cost of installing FGDs in all of India’s power plants would be Rs 2.4 lakh crore, which is an investment that should be carefully ‘scrutinised’. “Indian coal has very low sulphur content, and in many power plants the Ministry found that even without FGDs, the national ambient air quality standards were met,” explained Alok Kumar, former Union power secretary. “And given how FGDs increase electricity costs for consumers and also CO2 emissions, the government decided to only mandate it where necessary.” Sulphur dioxide is one of the byproducts of coal and lignite thermal power plants, and is a ‘criteria pollutant’ according to CSE. An IIT Delhi study from 2022 describes how sulphur dioxide can turn to sulphate particulate matter during and after emissions, a main component of PM2.5. SO2 has been variously ascribed to different health effects like respiratory problems and lung disorders since 2005, both by Indian and international sources. Most FGD systems use limestone or other alkaline products to remove sulphur dioxide from the gases released during the coal-firing process in power plants. However, the MoEFCC said it is necessary to examine the issue in an Indian context. “Current exposure levels provide no credible evidence to suggest that SO2, under prevailing ambient conditions, is a major public health concern,” read the Ministry’s post on X. The FGD compliance story, so far The MoEFCC first decided to implement sulphur dioxide regulation norms in 2015, and gave thermal power plants until 2017 to install FGD systems. Thermal power plants make up 46 percent of India’s total electricity capacity, and 70 percent of electricity generation. An independent analysis by the Centre for Research on Energy and Clean Air in 2024 revealed that India was the largest producer of SO2 from electricity generation. In 2022-23, the study showed that coal power plants produced 4327 kilotonnes of SO2, which was 240 times more than what was produced by burning 8.9 million tonnes of paddy. A CSE factsheet describes that the power ministry in 2015 put forth a new plan to extend the emissions compliance deadline to 2024, and was granted an extension until 2022. Since then, the deadline has been extended three more times, before the 11 July order, which extended it for the sixth time after “consultations with stakeholders and research institutes.” According to the MoEFCC’s note, 94 percent of the coal used in the power plants is domestic coal, which only has 0.5 percent sulphuric content, much lower than the coal used elsewhere. It also said that 490 out of 492 cities monitored in 2023 were within the prescribed SO2 levels in their ambient air quality levels. “Government sources have said that Indian coal has low sulphuric content, but they also say it has low calorific value, so more coal is needed to produce the same 1W of electricity. This increases SO2 production, too,” said Verma. “Also, SO2 is a problem because it gets converted to sulphate matter, which forms PM2.5. That happens over a long period and has transboundary impacts.” The Ministry’s note pointed to a 2024 IIT Delhi report, which says the contribution of sulphate to PM2.5 and PM10 is between 2 and 6 percent, and that FGD installations in power plants would only result in a “marginal improvement” of air quality. However, this study directly contradicts the 2022 study conducted by the same team, which had said installing FGDs would decrease surface sulphate aerosols even in areas 200 km away from the power plants. “It is very worrying that the number of people who may suffer or die is not being acknowledged or addressed in any of the reports. Scientific articles showed that coal-fired power plants led to 47,000 deaths in 2014, 62,000 deaths in 2017, and 78,000 deaths in 2018,” reads an article by the Centre for Research on Energy and Clean Air (CREA) in 2025. However, the Ministry said it is committed to a “comprehensive, science-based strategy” for air quality management, and that regulations for SO2 control should not be dictated by “rhetorical observations” but by real-time impacts on PM2.5.

Ministry supports revised SO2 emission norms, slams critics

The government on Monday defended its recent move to ease sulphur dioxide (SO₂) emission norms for thermal power plants, saying the decision was based on detailed scientific studies and stakeholder consultations, and that media reports terming the move a “regulatory dilution” have “grossly misinterpreted” the notification. The statement came days after the Union environment ministry on July 11 extended deadlines and exempted a large number of coal plants from installing flue gas desulphurisation units. “The media reports misrepresent both the scientific evidence and the environmental policy rationale underlying the revised notification,” the ministry said in its statement on Monday. It said the revised norms were framed after “extensive consultations with stakeholders and research institutions regarding the effectiveness and rationale behind stack emission standards for SO2 on 537 TPPs throughout the country, and its role in overall ambient air pollution of the region.” Further, the ministry said sulfate aerosols from SO2 constitute a relatively small fraction of PM 2.5, suggesting that was not a major public health issue, as suggested by environmental groups. “Current exposure levels provide no credible evidence to suggest that SO2, under prevailing ambient conditions, is a major public health concern. Moreover, sulphate aerosols formed from SO2 constitute a relatively small fraction of PM2.5,” it said. Addressing SO2 emissions is critical due to their contribution to secondary particulate pollution, experts have warned. Quoting a study by IIT Delhi, the ministry said, “A detailed analysis carried out by IIT Delhi shows that sulfate contributes only 0.96 per cent to 5.21 per cent of PM2.5 and 0.57 per cent to 3.67 per cent of PM10 in cities near TPPs (thermal power plants).”The ministry said the assertion that sulphur compounds contribute 12-30 per cent of PM2.5 is an unsubstantiated claim and not supported by any rigorous scientific studies conducted in major Indian cities and it significantly overstates the contribution of SO2 in India’s particulate pollution burden. On July 12, Centre for Science and Environment said: “The revised notification weakens India’s clean air ambitions by diluting or removing SO₂ norms for Category B and C thermal power plants, which together represent most of the country’s coal capacity. Together, these exemptions threaten to derail progress on industrial air pollution control, compromise public health, and reduce the effectiveness of India’s environmental regulations.”

India can't wish away coal - but can it be made cleaner?

"This means that there is no other option [other than thermal energy for constant supply] unless and until we have large-scale storage quantities in the system," said Rajiv Porwal, director with Grid India, the grid controller of India under the ministry of power, speaking at the 1July event, organised by the Centre for Science and Environment (CSE). India has always taken a hard position on coal, arguing that it is crucial for its energy security and developmental needs. But energy experts and environment campaigners are increasingly saying it should at least try to decarbonise or curtail emissions from coal-fired power plants, if it can't be phased out altogether. "You can't wish away coal," Ashok Lavasa, a former secretary of union ministries of finance, and environment, forest and climate change, said at an event on 1 July. "The question is, if coal is king, then can it be a benevolent king?" This signals to the fact that, realistically speaking, coal - albeit cleaner coal - may remain the primary power source of energy in India, despite years of international climate talks asking for the highly polluting fossil fuel to be phased out entirely. But why has India - the world's third largest carbon emitter - decided to stick to coal in the first place? After all, the country has international obligations to significantly cut its carbon emissions, along with its own target to bring down the levels to net zero by 2070. A part of the answer lies in the rising power demands of the country. India's electricity demand has grown by more than 9% between 2021 and 2025, surpassing a previous prediction of 6.6% - and it is now forecasted to double by 2030. Coal-fired power plants have generated more than 70% of the total electricity supply every year since the early 2000s - a figure that remains unchanged. But the environmental cost of this reliance on coal is huge. Estimates suggest that India's electricity generation alone accounts for more than 40% of the annual carbon emissions – and nearly three-quarters of that electricity comes from coal-burning. The country has made progress in meeting its renewable energy targets - it contributes 46% of India's total installed capacity - but renewable sources have limitations. They generate electricity when the sun is up and the wind is blowing. Even at daytime, experts say, supply from renewables can fluctuate, whereas thermal plants remain a constant source of electricity and are able to cater to peak demand in the evenings and at nighttime. What's more, India's energy storage capacity - or the ability to store excess electricity from renewables at daytime - has not been able to keep pace with the expansion of resources. "This means that there is no other option [other than thermal energy for constant supply] unless and until we have large-scale storage quantities in the system," said Rajiv Porwal, director with Grid India, the grid controller of India under the ministry of power, speaking at the 1July event, organised by the Centre for Science and Environment (CSE). Experts say constant supply from thermal plants is crucial for the stability of the grid, or the network of towers and transmission lines that carries electricity from power plants to consumers. "Any large mismatch of demand and supply will destabilise the grid and that can mean power-cuts and blackouts, similar to what we recently saw in Spain," says Anjan Kumar Sinha, an independent power sector expert. With all these factors at play, India is looking to reduce emissions from coal-fired power plants, instead of phasing out coal completely. A recent report by the CSE said that decarbonisation from coal-based thermal plants alone can cut down the country's greenhouse gas emissions by 30%. This is particularly significant given the country's commitment to reduce emissions intensity (carbon emissions produced per unit of a country's economic output) by 45% by 2030 under the United Nations Framework Convention on Climate Change.

India’s Struggle with Coal: The Challenges of Transitioning to Clean Energy

India’s reliance on coal for energy generation remains a contentious issue as the country grapples with rising electricity demands and international climate commitments. Despite being the world’s third-largest carbon emitter, India continues to prioritize coal, which accounts for over 70% of its electricity supply. Experts argue for a shift towards decarbonization of coal-fired power plants, highlighting the need for cleaner energy solutions while acknowledging the challenges posed by renewable energy sources. Coal’s Dominance in India’s Energy Landscape India’s energy strategy has long been anchored in coal, which is viewed as essential for meeting the country’s growing electricity demands. The nation has seen a significant increase in electricity consumption, with a growth rate exceeding 9% from 2021 to 2025, surpassing earlier projections. This surge in demand is expected to double by 2030, reinforcing coal’s role as the primary energy source. Since the early 2000s, coal-fired power plants have consistently generated more than 70% of India’s total electricity supply. However, this heavy reliance on coal comes at a steep environmental cost, contributing to over 40% of the country’s annual carbon emissions. While India has made strides in renewable energy, accounting for 46% of its total installed capacity, these sources face inherent limitations. Renewable energy generation is contingent on weather conditions, leading to fluctuations in supply. Consequently, coal remains a reliable option for meeting peak electricity demands, particularly during evenings when renewable sources may not suffice. Challenges in Transitioning to Cleaner Energy Despite the push for renewable energy, India’s energy storage capacity has not kept pace with the growth of renewable resources. Experts emphasize the need for large-scale energy storage solutions to ensure a stable electricity supply. Rajiv Porwal, director of Grid India, highlighted that without adequate storage, thermal energy remains the only viable option for consistent electricity supply. This situation raises concerns about grid stability, as any significant mismatch between demand and supply could lead to power cuts and blackouts. To address these challenges, India is focusing on reducing emissions from coal-fired power plants rather than phasing out coal entirely. A recent report from the Centre for Science and Environment (CSE) suggests that decarbonizing coal-based thermal plants could reduce greenhouse gas emissions by 30%. This aligns with India’s commitment to decrease emissions intensity by 45% by 2030 under international climate agreements. Strategies for Emission Reduction Experts propose several strategies to enhance the efficiency of thermal plants and reduce emissions. One approach involves improving the operational efficiency of these plants, allowing them to run at lower capacities without compromising electricity supply. Ramesh Veeravalli from India’s Central Electricity Regulatory Commission noted the technical feasibility of lowering the minimum running capacity of thermal plants. Additionally, adopting carbon capture technologies could help mitigate emissions, although current methods capture only a small fraction of global emissions. Another innovative solution involves substituting coal with agricultural residues in thermal plants, a practice that has shown promise in reducing coal usage in regions like Delhi. However, widespread adoption of this method across the country remains limited.

Air Pollution: Delhi awaits Cloud Seeding

Delhi, which suffers from severe pollution every, awaiting the implementation of cloud seeding or artificial rain for months as the Delhi government has been considering it to provide clean air to its citizens. The city remained most polluted by a wide margin during the 2024-25 winter, with an average PM2.5 concentration of 175 micrograms per cubic metre, as per Centre for Science and Environment. According to a report by the Energy Policy Institute at the University of Chicago (EPIC), the air pollution in the city is reducing citizens’ life expectancy by an average of 11.9 years compared to the World Health Organisation’s (WHO) guidelines. Now, in order to combat air pollution, Delhi is set to carry out artificial rain through cloud seeding flights between August 30 and September 10. The operation, originally scheduled for July 4 to 11, has been postponed following recommendations from experts at the India Meteorological Department (IMD) and the Indian Institute of Tropical Meteorology (IITM), Pune. The Rs 3.21 crore pilot project, titled ‘Technology Demonstration and Evaluation of Cloud Seeding as an Alternative for Delhi NCR Pollution Mitigation,’ was announced by Environment Minister Manjinder Singh Sirsa. The initiative will use five specially modified Cessna aircraft to disperse rain-inducing materials over parts of the capital, with the goal of washing out airborne pollutants. Initial operations will focus on low-security air zones in northwest and outer Delhi. Each flight, or sortie, is expected to last about 90 minutes and will cover approximately 100 square kilometres. What is Cloud Seeding? Cloud seeding involves introducing substances like silver iodide, dry ice, or salts into clouds to encourage precipitation. This method is used globally to address issues such as drought, inadequate snowfall, or persistent smog and fog. The formulation developed for this project by IIT Kanpur includes silver iodide nanoparticles, iodised salt, and rock salt. The decision to delay the cloud seeding operations came after meteorological experts advised that the initial July window, though during monsoon season, was not ideal for effective cloud seeding. Critics had questioned the timing, arguing that rain during monsoon would not significantly help reduce pollution and would waste public funds. However, experts clarified that the presence of active monsoon clouds is essential for cloud seeding to work. The project marks a significant step in Delhi’s ongoing efforts to find innovative ways to address its persistent air quality challenges.

Sulphur dioxide emission norms relaxed for thermal power plants

The central government has granted widespread exemptions to thermal power plants from complying with air pollution emissions norms, in a move experts say could be detrimental to public health. On July 11, the Ministry of Environment, Forests, and Climate Change issued a notification exempting thermal power plants which are due to retire by 2030 from complying with sulphur dioxide emissions standards, as long as they declare their year of retirement to the Central Pollution Control Board and the Central Electricity Authority. As per the notification, only ‘Category A’ plants – those located within 10 kilometres of the National Capital Region and other cities with populations exceeding one million – need to comply with sulphur dioxide emissions standards by December 2027. Plants that have obtained environmental clearance and are located within a 10-kilometre radius of other critically polluted areas – ‘Category B’ – have the option of complying with norms by December 2028 or appealing to the centrally-appointed Expert Appraisal Committee for exemption. Whether up-and-coming plants in this category need to comply with emissions norms will be determined through the environmental clearance process, the notification says. The most dramatic change is for ‘Category C’ plants that are neither located close to big cities nor to critically polluted areas, but which make up the vast majority of thermal power plants in the country. The notification states that these plants needn’t comply with sulphur dioxide standards at all, as long as the height of their chimneys (stacks) meet required limits. Once released into the atmosphere, sulphur dioxide can react with other pollutants to form hazardous PM2.5 particles. Between June 2022 and May 2023, thermal power plants released approximately 4,327 kilotonnes of sulphur dioxide. Non-retiring and non-compliant plants will have to pay environmental compensation of up to Rs. 0.40 per unit of electricity generated, depending on the tenure of non-compliance. The government has said the changes were introduced because of limited availability of flue gas desulphurisation (FGD) technologies, supply chain issues, price escalations, and “low sulphur dioxide concentration in ambient air” — all reasons that have been challenged by policy experts and scientists. Previously, all thermal power plants, regardless of category, were mandated to meet emissions standards by installing FGD technology. “Granting such a large-scale exemption undermines the effectiveness of the emission standards and poses a serious risk to public health and environmental sustainability,” said Shreya Verma, programme manager at the Centre for Science and Environment, in a statement.

पिछले कुछ महीनों से एक ऐसा समय देखने को मिल रहा है जो इस वक्त की हकीकत है लेकिन यह अवास्तविक सा लगता है। हमारी दुनिया एक लट्टू की तरह धुरी पर घूमती प्रतीत होती है जिस पर लगता है कि किसी का नियंत्रण नहीं है। मैं यह विशेष रूप से उन लोगों के लिए कह रही हूं जिन्होंने मेरी तरह ही अपने जीवन के पांच दशक पूरे कर लिए है और जो औपनिवेशिक काल के बाद के दौर में बड़े हुए। इस पीढ़ी ने एक ऐसी वैश्विक व्यवस्था देखी है जिसमें बेहद असमानता थी लेकिन फिर भी उस व्यवस्था में सुधार संभव लगता था। संभवतः वह थोड़ी मासूमियत का दौर था। लेकिन हमें वैश्विक कानून के शासन से उम्मीदें थीं। निश्चित तौर पर संयुक्त राष्ट्र की इसमें एक अहम भूमिका थी। भले ही सुरक्षा परिषद, तब और अब, एक ऐसी संस्था थी जो एक असमान और अनुचित वैश्विक शक्ति व्यवस्था को प्रतिबिंबित करती थी – लेकिन यह गलत के खिलाफ, सही के साथ खड़ा था। अब ऐसा लगता है कि जैसे हमारे पैरों तले जमीन खिसक गई है और हम खो गए हैं। निश्चित रूप से, मैं इस वैश्विक व्यवस्था को नहीं समझ पा रही हूं जहां कोई देश किसी भी उकसावे के बिना, दूसरे देश पर बमबारी करते हुए एकतरफा कार्रवाई कर सकता है और दुनिया बिल्कुल असहाय और खामोश होकर यह सब देखती रहती है। अब आलम यह है कि हम दूसरे देश में सत्ता परिवर्तन की बात सुनते हैं और इसे बेहद सामान्य मानकर टाल देते हैं। हम तनाव न लेने के लिए ज्यादा से ज्यादा यही करते हैं कि टीवी चैनल बदल देते हैं क्योंकि हम इसे और नहीं देख सकते। हम पूरी तरह से लाचार हैं। ईरान पर हाल का हमला केवल अमेरिका या इजरायल के सही या गलत होने से नहीं जुड़ा है बल्कि यह नियमों पर बनी वैश्विक व्यवस्था के भविष्य से जुड़ा है जिस पर विभिन्न राष्ट्रों ने सहमति जताई थी और फिर वैश्विक संस्थाओं के माध्यम से लागू किया था। इस मामले में ईरान, परमाणु अप्रसार संधि (एनपीटी) का एक हस्ताक्षरकर्ता देश है और यह संधि, परमाणु हथियारों के खिलाफ एक अंतरराष्ट्रीय समझौता है। वर्ष 1970 में लागू हुई इस संधि को व्यापक रूप से सफल माना जाता है। इस संधि से 191 देश, पक्षकार के तौर पर जुड़े हैं और उन्होंने यह स्वीकार किया है कि ‘परमाणु हथियारों का प्रसार, परमाणु युद्ध के खतरे को गंभीरता से बढ़ाएगा।’ इस संधि के एक हस्ताक्षरकर्ता देश के रूप में, ईरान को परमाणु हथियार हासिल करने से प्रतिबंधित किया गया है। वियना में मौजूद, अंतरराष्ट्रीय परमाणु ऊर्जा एजेंसी (आईएईए) को यह सुनिश्चित करना होता कि इन नियमों का पालन किया जाए। ईरान आईएईए की सुरक्षा प्रणाली के नियमों के अंतर्गत आता है और इस क्षेत्र की भू-राजनीतिक अहमियत को देखते हुए, इस क्षेत्र को व्यापक रूप से कड़ी निगरानी व्यवस्था के दायरे में माना जाता है। एनपीटी के तहत, पांच देशों को परमाणु हथियार संपन्न राष्ट्रों के रूप में मान्यता मिली है जिनमें अमेरिका, रूस, ब्रिटेन, फ्रांस और चीन शामिल हैं और इसमें आप यह तर्क दे सकते हैं कि यह भेदभावपूर्ण है। ये सभी देश संयुक्त राष्ट्र सुरक्षा परिषद के स्थायी सदस्य भी हैं। भारत और पाकिस्तान ने अपनी परमाणु-हथियार क्षमता घोषित की है लेकिन एनपीटी पर हस्ताक्षर नहीं किए हैं, वहीं उत्तर कोरिया इससे बाहर हो चुका है। लेकिन इजरायल की वजह से यह स्थिति और भी ‘अवास्तविक’ हो जाती है जिसने ईरान की परमाणु महत्त्वाकांक्षाओं को अपने अस्तित्व के लिए खतरा बताया है जबकि उसने खुद भी कभी एनपीटी पर हस्ताक्षर नहीं किए हैं। व्यापक तौर पर यह बात स्वीकारी जाती है कि इजरायल का एक गुप्त परमाणु-हथियार कार्यक्रम चल रहा है। यहां एक देश, वैश्विक नियमों से बंधा हुआ है और उस पर एक ऐसे देश द्वारा हमले किए जा रहे हैं खुले तौर पर वैश्विक नियमों और संस्थाओं को नकारता है। ऐसे में यह एक बहुपक्षवाद या अव्यवस्था पर नहीं बल्कि व्यवस्थाओं पर आधारित वैश्विक व्यवस्था के भविष्य के बारे में क्या संदेश देता है? मई महीने में ईरान पर आईएईए की रिपोर्ट में इसके महानिदेशक ने कुछ मुद्दों पर अपने निरीक्षकों की चिंता उठाई थी जिनमें ‘संवर्धित यूरेनियम का तेजी से भंडारण’ करने की बात शामिल थी। लेकिन रिपोर्ट में कहीं भी यह नहीं कहा गया है कि उनके पास इस बात के सबूत हैं कि ईरान के पास परमाणु हथियार हैं जिसके लिए किसी देश को यूरेनियम को 90-95 फीसदी तक संवर्धित करने की आवश्यकता होती है। इसके अलावा इस मुद्दे पर अगला कदम, संबंधित पक्ष के साथ चर्चा करना होना चाहिए था और अगर आवश्यक हो तब इस मामले को संयुक्त राष्ट्र सुरक्षा परिषद में ले जाना चाहिए था। इस तरह की चिंता का उपाय, देश के परमाणु ऊर्जा और अन्य संबंधित स्थलों पर बमबारी करना नहीं हो सकता, जिससे विनाशकारी रिसाव का खतरा पैदा हो जाए। इन सभी परिस्थितियों में हमें पूछना होगा कि इसके कारण आईएईए की विश्वसनीयता कहां रह जाती है? आईएईए सभी देशों में सुरक्षा उपायों को बनाए रखने की भूमिका कैसे निभा सकता है? यदि किसी दूसरे पर बमबारी करने के लिए केवल शक्ति और आक्रामक बल का उपयोग करना ही काफी है तब देशों को कानून के शासन की औपचारिकताएं बनाए रखने की परवाह क्यों करनी चाहिए? संयुक्त राष्ट्र और इसके महासचिव की भूमिका तार-तार हो गई है क्योंकि अब इनकी भूमिका केवल प्रेस विज्ञप्ति जारी करने और ऐसी सलाह देने तक सीमित है जिसे कोई नहीं सुनता। हमें वास्तव में यह पूछने की जरूरत है कि ये संस्थाएं अपनी जमीन पर क्यों नहीं खड़ी हो रही हैं या फिर इस तरह की अव्यवस्था को दूर करने में कोई भूमिका क्यों नहीं निभा रही हैं? क्या ये इस हद तक समझौता कर चुकी हैं या उन्होंने कुछ देशों के आक्रामक व्यवहार के सामने हार मान ली है? यह एक परस्पर निर्भर वैश्विक व्यवस्था के लिए आगे बढ़ने का रास्ता नहीं है। मैं यह इसलिए पूछती हूं क्योंकि यहां बहुत कुछ दांव पर लगा है। हम जानते हैं कि जलवायु परिवर्तन का खतरा वास्तविक है और इसके लिए दुनिया को एक साथ काम करने की आवश्यकता है। यह साझा संसाधनों का एक वास्तविक संकट है और इसे सभी की भागीदारी के बिना हल नहीं किया जा सकता है। एक टूटी हुई वैश्विक व्यवस्था जिसमें वैश्विक संस्थाएं बरबाद और कलंकित हो चुकी हैं, वे ऐसे और इसी तरह के अन्य वैश्विक मुद्दों का समाधान खोजने के लिए काम नहीं करेंगी। हम जानते हैं कि फिलहाल जिसकी लाठी उसकी भैंस है, लेकिन यह मर्दाना प्रकृति की और युद्धरत वैश्विक अव्यवस्था, मनुष्यों या प्रकृति के साथ शांति व्यवस्था नहीं बना पाएगी। (लेखिका सेंटर फॉर साइंस ऐंड एनवायरनमेंट से जुड़ी हैं)

Majority ofthe coal-based TPPs spared from installing anti-pollution flue gas desulphurization systems

NEW DELHI: In a move that may spare majority of the coal- and lignite-based thermal power plants (TPPs) in the country from installing anti-pollution ue gas desulphurisation (FGD) systems, the environment ministry has issued a revised notication regarding Sulphur Dioxide (SO₂) emission standards for such plants and introduced a new compliance framework based on categories exemptions, penalties, and extensions. All these power plants were earlier expected to install FGD equipment to meet the SO2 standards by the previous deadline but many of them failed to do it. The FGD is a process of removing sulphur compounds from the exhaust emissions of fossilfueled power stations The TPPs that do not retire by December 31, 2030 and fail to meet pollution standards (especially for Sulphur Dioxide) within their respective deadlines will have to pay a penalty called environmental compensation. Their compliance deadlines have already been extended four times since 2017. Though there will not be any exemption for existing and under-construction TPPs within 10 km of the air pollution hotspot, the national capital region (NCR), or cities with 1 million plus population (Category A cities, comprising 11% of total 600 of plants in the country) under the revised notication, it will be the governmentʼs discretion to decide exemption of another 11% such plants located within 10 km of Critically Polluted Areas (CPAs) or Non-Attainment Cities (Category B) beyond the NCR. The remaining TPPs (78% of the total) in the rest of the cities which fall under Category C will be fully exempted from adhering to the anti-pollution norms relating to the Sulphur Dioxide (SO₂) emission standards. "The revised notication weakens Indiaʼs clean air ambitions by diluting or removing SO₂ norms for Category B and C thermal power plants, which together represent most of the country ʼs coal capacity. Together, these exemptions threaten to derail progress on industrial air pollution control, compromise public health, and reduce the eectiveness of Indiaʼs environmental regulations, " said Nivit Kumar Yadav, director, industrial pollution team of the Centre for Science and Environment (CSE). The CSE analysis shows that the exempting all Category C plants from SO₂ norms simply based on location ignores cumulative pollution, especially in areas like Singrauli or Korba which are not "ocially" CPAs but are severely impacted. Notably, more than 75% of Indiaʼs thermal power capacity— amounting to approximately 166,885.5 MW—falls under Category C. "Granting such a large-scale exemption undermines the eectiveness of the emission standards and poses a serious risk to public health and environmental sustainability, " said Yadav. The notication, issued on Saturday, came six months aer the ministry gave the TPPs a fourth extension by stretching the timeline by three more years to install pollution control equipment. Giving

Centre extends SO2 norm compliance deadlines for thermal power plants

New Delhi: The union environment ministry has issued a notification once again extending the timelines for thermal power plants to comply with sulphur dioxide (SO2) emission standards. According to expert analysis, the notification also effectively exempts a large proportion of thermal power plants—representing more than 75% of India’s thermal power capacity—from complying with SO2 norms, provided they ensure compliance with stack height regulations. Addressing SO2 emissions is critical due to their contribution to secondary particulate emissions. The new notification, issued on July 11, introduces a revised compliance mechanism for SO2 norms applicable to coal- and lignite-based thermal power plants. It categorises these plants into three groups: Category A: Located within a 10 km radius of the National Capital Region (NCR) or cities with a population exceeding one million. Category B: Located within a 10 km radius of Critically Polluted Areas (CPAs) or Non-Attainment Cities. Category C: All other plants not included in Categories A or B. Overall, if a thermal power plant plans to retire before December 31, 2030, it is not required to meet the SO2 emission standards, provided it officially submits an undertaking to the Central Pollution Control Board (CPCB) and Central Electricity Authority (CEA), stating that the plant will be retired by December 31, 2030. All existing and under-construction category A plants must meet SO2 norms by the end of 2027. For category B plants, the Centre will determine whether SO2 standards will apply. Existing plants that have already received environmental clearance can now apply for a review of the applicability of SO2 norms. This application must be submitted on the PARIVESH portal within six months of the notification date. Category C thermal power plants are now exempted from SO3 emission standards. Instead, they must comply with stack height requirements as per an earlier notification issued in 1990. All existing category C thermal power plants must ensure compliance with the stack height rule by December 31, 2029. “Exempting all category C plants from SO3 norms simply based on location ignores cumulative pollution, especially in areas like Singrauli or Korba which are not ‘officially’ CPAs but are severely impacted. Notably, more than 75% of India’s thermal power capacity—amounting to approximately 166,885.5 MW—falls under category C. Granting such a large-scale exemption undermines the effectiveness of the emission standards and poses a serious risk to public health and environmental sustainability,” a statement issued by Centre for Science and Environment on Saturday said. This is not the first time that the ministry of environment, forest and climate change (MoEFCC) has extended the timelines for thermal power plants to comply with SO2 norms. HT reported on September 7, 2022, that the environment ministry extended the deadline to meet SO2 norms to December 31, 2027, for units scheduled to retire, and to December 31, 2026, for plants that will continue operations beyond that period. The ministry had already given prior extensions to coal-fired power plants for meeting SO2 and other pollution norms. Again, through an order dated December 30, 2024, the MoEFCC further extended the compliance timelines for SO2 emissions to December 2027, December 2028, and December 2029 for category A, B, and C thermal power plants, respectively. Addressing SO2 emissions is critical due to their role in the formation of secondary particulate matter 2.5 (PM2.5), a major air pollutant identified by scientists as a significant health hazard. Sulphur dioxide emission standards were first notified by the centre in 2015 and have been amended periodically since. “Many representations were received regarding exemption or relaxation in timelines of these emission standards due to limited availability of technology providers, its techno-economic feasibility, negative impact of COVID-19 pandemic on supply chain, price escalation due to high demand and low supplies, low SO2 concentration in ambient air and heavy burden on consumer due to increase in electricity prices etc., and explicit recommendation of the Ministry of Power was received in this regard,” a notification issued on July 11 said. The notification also said that several studies were conducted by research institutions to assess the effectiveness and rationale behind the SO2 standards and their impact on regional ambient air pollution. Stakeholder consultations were held with industry, the ministry of power, CPCB, scientific institutions, and others. It further states that a committee under the CPCB was constituted to assess the issue holistically. The committee reviewed study reports, relevant data, and implementation challenges before making its recommendations. “CPCB, after detailed analysis, has submitted its recommendation based on its study on National Ambient Air Quality Standards of Sulphur dioxide across most of the regions of the country; resource conservation in terms of avoiding additional consumption of water, auxiliary power, and limestone; increase in carbon footprint or Carbon dioxide emission into the atmosphere due to operation of control measures being deployed, and mining and transportation of limestone required for these control measures; the techno-economic feasibility of implementation of such control measures in all coal or lignite based thermal power plants…” the notification added.

Solutions for Delhi Pollution problems

Studies indicate that Industries contribute 11% and the dust-heavy construction sector adds 7% to Delhi’s pollution. In contrast, data from the Indian Institute of Tropical Meteorology shows stubble burning contributes just 1.3% to Delhi’s pollution. Similarly, an analysis by CSE (Centre for Science and Environment) highlighted that 50.1% of the pollution is contributed through transportation, while stubble burning contributes only 8.9% to it. Delhi has 1.2 crore registered vehicles, including 33.8 lakh private cars (2020-21 data) A study by the Centre for Research on Energy and Clean Air found that NCR’s thermal power plants emit 281 kilotonnes of sulphur dioxide annually – 16 times more than the emissions from burning 8.9 million tonnes of paddy straw in Punjab and Haryana. With coal still supplying over 70% of Bharat’s electricity, and the fact that 33.6% of Delhi’s electricity – and a staggering 95% of Mumbai’s – comes from coal-fired power plants indicate that EV adoption targets for cleaner transport are superfluous and just symbolic. A report by Outlook Business, highlighted that GRAP (The Graded Response Action Plan) which is intended to effectively manage air quality in the NCR, suggests that primary pollution sources – vehicular emissions, construction activities, and industrial operations – must be controlled. Delhi Government had started implementing the GRAP-III and GRAP-IV measures from 2023 and 2024 respectively which attract tougher compliance guidelines for environment protection and pollution control. These guidelines are essential for maintaining stable air quality in large urban centres. As part of the National Clean Air Programme (NCAP), Bharat identified 131 non‑attainment cities—urban areas that chronically fail to meet air quality standards. in the Indo-Gangetic Plain (IGP) region, there are 39 non‑attainment cities. All 39 have officially prepared GRAP frameworks. However, these GRAP Guidelines are currently being implemented actively in Delhi-NCR Region, and down the line it will become imperative to apply these guidelines in several other cities in Bharat. In recent years, other cities like Mumbai (Air Quality Index, i.e., AQI 208 in November 2024), Bhopal (AQI above 300 in winter months) and Lucknow (AQI 306 in November 2024) reported severe air pollution.

Preserving Seed Sovereignty: NER’s heirloom challenge

The push for high-yielding varieties (HYVs) and hybrid seeds, driven by multinational corporations (MNCs) and our own National Agricultural Research System, poses a threat to the rich biodiversity of native (heirloom) seeds that have supported communities for centuries. This issue is particularly urgent in Northeast India, a biodiversity hot-spot that is home to unique land-races adapted to local micro-climates and soils. To protect this genetic wealth, ensure food security, and combat the risks of monoculture, there is a pressing need to establish community-led seed banks across the region. Through this article, I urge the state government to develop a plan to establish a network of community-driven seed banks in each of Meghalaya’s five agro-climatic zones. Importance of Native Seeds Native seeds, often referred to as land-races, are the result of many generations of both natural selection and adaptation. These seeds are suited to local environmental conditions, require fewer chemical inputs, and are resilient to stresses such as droughts, floods, and pests. Northeast India, recognized as one of the world’s 36 biodiversity hot-spots, is home to traditional crops such as rice, millets, spices, and pulses that thrive across various micro-climates, from Assam’s flood-prone plains to Arunachal’s hilly terrains. According to the 2022 ScienceDirect study, there are likely over 9,500 land-races of paddy alone in Northeast India. The evidence suggests high diversity, making Northeast India a key area for preserving agricultural heritage through community-led seed banks. These seeds are not just agrarian assets; they are cultural and nutritional treasures. Communities in the Northeast have cultivated unique varieties, such as Meghalaya’s red pumpkin and Assam’s flood-tolerant rice, which are integral to local diets and traditions. Navdanya (an NGO) has conserved 33 salt-tolerant and 54 flood-tolerant rice varieties in Odisha, highlighting land-races’ ability to withstand climate challenges. Unlike HYVs, which often prioritize yield over nutrition, native seeds offer diverse flavours, medicinal properties, and resilience. The Trap of High-Yielding Varieties and MNCs The Green Revolution of the 1960s shifted India’s focus toward HYVs, promising higher yields to support a growing population. While these varieties initially increased production, they also brought significant costs: a greater reliance on chemical fertilizers, pesticides, and irrigation, which harmed soil health and raised farming expenses. Now, the latest development: The Government of India’s National Mission on High-Yielding Seeds, launched in the 2025-26 Union Budget, aims to develop more than 100 new seed varieties, which could further reduce traditional seed diversity. Multinational corporations (MNCs) have capitalized on this shift, dominating seed markets with patented hybrids that often come with licensing restrictions. In NER, where small and marginal farmers are predominant, this model is especially harmful. The high cost of commercial seeds, coupled with their dependence on chemical inputs, burdens farmers with debt and restricts their autonomy. Additionally, monoculture farming promoted by HYVs makes crops more vulnerable to pests and diseases, as seen in the 2022 dwarf virus outbreak in Punjab’s paddy fields. Vandana Shiva of Navdanya, a leading advocate for seed sovereignty, has highlighted how seed monopolies driven by MNCs threaten biodiversity and increase chemical usage. The key point is that community seed banks are vital tools for preserving agricultural diversity and empowering farmers. The Centre for Science and Environment (CSE) estimates that community seed banks across India hold over 887 climate-resilient varieties, but poor documentation and funding limit their impact. Community seed banks are grassroots efforts that enable farmers to conserve, exchange, and multiply native seeds. In Karnataka, the GREEN Foundation has partnered with small farmers to establish seed banks, recognizing women as essential custodians of seed knowledge. Similarly, Navdanya’s 150 seed banks across 22 states have preserved over 4,000 rice varieties, demonstrating the scalability of such models. Northeast India: A Biodiversity Hotspot at Risk Northeast India’s agro-ecological diversity is unmatched, hosting thousands of indigenous crop varieties. For instance, the MS Swaminathan Research Foundation’s Tribal Agro-biodiversity Centre in Jeypore, Odisha, preserves over 1,200 rice varieties, many of which share genetic traits with Northeastern land-races. I once did a bit of research of my own, to discover that there are at least seven different land-races of chillies in the NER. I am aware of an initiative by a woman farmer from the West Khasi Hills who preserved a native land-race of paddy. In the Northeast, community seed banks can serve multiple purposes: (1) conserving genetic diversity, (2) providing access to climate-resilient seeds, and (3) promoting seed sovereignty. By involving local farmers, these banks help preserve traditional knowledge and practices, as seen in the Kolli Hills, where women farmers have revived millet cultivation through seed festivals. We must all note that many of these land-races are facing extinction due to the spread of commercial agriculture and insufficient conservation infrastructure. In the Northeast, where traditional seed-saving practices are still maintained, there is a unique opportunity to expand these efforts before the region’s genetic diversity is lost forever. A State-Led Scheme To harness the Northeast’s potential as a seed conservation hub for the country, I suggest that each state government develop a comprehensive plan to establish a network of community-led seed banks. Meghalaya stands out among the states in the region for its sensitivity toward farmers; therefore, it can take the lead in inspiring all Northeastern states for a national impact. Each state should set up a central traditional Seed Bank and create agro-climatic zone-specific seed banks within its jurisdiction. The proposed scheme could include the following components: 1. Establishment of community-led seed banks: Develop a network of community-managed seed banks in each agro-climatic zone of the state, connected to a central conservation centre. These banks should record and store land-races, with an emphasis on climate-resilient varieties. 2. Farmer Training and Incentives: Educate farmers, especially women, in seed selection, storage, and organic farming techniques. Provide incentives such as certification as “biodiversity custodians,” an approach pioneered by an NGO, ‘Sahaja Samrudha’. 3. Policy Support and Funding: Allocate funds to develop infrastructure, such as storage facilities, using traditional methods. Policies should also prioritize native seeds in public procurement programmes, ensuring market demand. The relentless pursuit of high-yielding varieties should be pushed back. 4. Collaboration with NGOs and Research Institutions: Partner with organizations like Navdanya, CSE, and MSSRF to leverage their expertise in seed conservation. Empower the farmers to undertake surveys for identifying new landraces. Organize regional workshops to address this issue and develop a detailed, comprehensive action plan. 5. Public Awareness Campaigns: Promote the nutritional and ecological benefits of native crops through seed festivals and ‘native cooking’ competitions to counter the urban preference for polished, high-yielding grains and pulses. Challenges and the Way Forward Community seed banks face challenges like funding shortages, declining interest in traditional seeds, and competition from HYVs. To tackle these issues, the state scheme must integrate seed conservation into broader agricultural policies, ensuring native seeds are not overshadowed by commercial interests. Successful models such as the Deccan Development Society’s work (Zaheerabad, Telangana) with 5,000 women farmers near Hyderabad can help the Northeast build a robust seed-saving movement. The Northeast’s biodiversity is a national treasure, and protecting it is essential. A state-led plan to establish community seed banks will not only safeguard land-races but also empower farmers, decrease dependence on multinational corporations, and promote the development of a resilient food system. The time to act is now—before the region’s genetic heritage is lost forever. This is the kind of task that the BRDC should consider working along with the Agriculture Department. I hope someone out there reads articles like this one. The writer is former member of the IAS

Under the agreement, MNIT Jaipur and CSE will jointly strengthen technical, advisory, and knowledge-based support in key areas such as energy and climate action, multi-sector clean air strategies, waste and dust management, and sustainable urban mobility. Officials said this collaboration will help promote structured training, resource sharing, and curricular innovation, with a concentrated focus on developing sustainable and liveable urban habitats.

Why Delhi’s crackdown on old vehicles may not be effective in tackling air pollution

“Older vehicles do require action, but a standalone ban dependent on just age alone is concerning,” said Anumita Roychowdhury, executive director of research and advocacy at the Delhi-based Centre for Science and Environment. On July 1, the Delhi government undertook a significant measure to tackle air pollution: it banned fuel stations from selling fuel to diesel vehicles that were more than ten years old and petrol vehicles that were more than 15 years old. Vehicular emissions are one of the leading causes of air pollution in Delhi through the year. They can contribute between one-third and two-thirds of the capital’s toxic air, a 2018 analysis showed. The government’s move was based on a “directive order” issued by the Commission for Air Quality Management in April. The commission is a statutory body established by the Union environment ministry to manage the air quality of the National Capital Region and its adjoining areas. To identify such “end-of-life” vehicles, automated camera systems were installed in 498 petrol stations in Delhi to scan the number plates of vehicles that entered – if any was found to be above the age limit, or to not possess a pollution under control certificate, the station was to deny it fuel. Authorities also cracked down on overage vehicles: across the city, 87 such vehicles were impounded and 176 notices were issued to owners of others. But these apparently decisive moves belied considerable confusion over strategy and policy within the government. This became apparent just three days later on July 3, when the Delhi government asked the commission to reconsider its guidelines because it was facing challenges in implementing the ban: perhaps most significantly, faulty camera systems were often erroneously flagging newer cars. Delhi’s chief minister, Rekha Gupta, posted on X that the move was “adversely affecting the daily lives and livelihoods of millions of families”. After deliberations between Delhi government and the Commission for Air Quality Management, the commission on July 8 decided to “partially amend” its earlier instructions, and instead direct that the fuel ban be activated from November 1 onwards in five “high vehicle density districts” – Gurugram, Faridabad, Ghaziabad, Gautam Budh Nagar and Sonipat. From April 2026, the ban will extend to the rest of the National Capital Region. Even as the ban is set to return, experts argue that rather than imposing blanket bans, a more targeted approach to removing polluting vehicles from the streets would be more effective, and easier to implement on a large scale. “Older vehicles do require action, but a standalone ban dependent on just age alone is concerning,” said Anumita Roychowdhury, executive director of research and advocacy at the Delhi-based Centre for Science and Environment.
