What's making Delhi air deadlier

New Delhi: Delhi’s skies have donned a grim shade of grey. Emissions from vehicles, fumes from industries and smoke from local fires have shrouded the air, choking residents all season. But experts are worried about a bigger problem—the pollutants in Delhi’s air are getting finer and deadlier. The Central Pollution Control Board (CPCB), the apex air quality monitoring body in India, assesses a city’s pollution levels on the basis of three primary parameters—air quality index or AQI (a 24-hour average of major pollutants), PM10 (coarse particulate matter usually comprising dust), and PM2.5 (ultrafine particles typically released through combustion). However, these might not be providing an accurate picture of how dangerous the city’s air is. Research studies and environmentalists warn that while sources of pollution in Delhi-NCR have largely remained the same over the last few years—stubble fires, vehicular emissions, waste burning and industrial emissions—pollution particles are reducing in size.

World’s record heat is worsening air pollution and health in Global South

Humanity achieved a fateful milestone last year. The European Union’s Copernicus Climate Change Service has officially declared 2024 the hottest year on record, and the first year in history with an average global temperature rising 1.5° Celsius (2.7° Fahrenheit) above the pre-industrial period — significantly increasing dangerous climate risks. In fact, 2023 and 2024 may well be the hottest years in 100,000 years, with all indicators pointing to it getting hotter, bringing ever-worsening global impacts. “The temperature-related extreme events witnessed [last Norther Hemisphere] summer will only become more intense,” warned Samantha Burgess, deputy director of the Copernicus Climate Change Service. In 2024, extreme heat enveloped whole regions of the world for weeks on end, with severe unprecedented consequences. A deadly heat wave killed at least 1,300 people during the annual Hajj pilgrimage in Saudi Arabia, while the worst drought in a century gripped Southern Africa, leaving 21 million children malnourished. Record drought also devastated South America, reducing Amazon rivers to their lowest levels ever recorded. North America wasn’t spared either. Heat domes — stalled high pressure systems that retain and intensify temperatures — blanketed vast parts of the U.S. and killed more than 100 people in Mexico. But less noticed, and harder to track, is the way in which oppressive heat helps degrade air quality, making people sick. While air pollution sources are typically local or regional, the invisible hand of climate change is further deteriorating air quality around the planet. Stubbornly persistent heat waves, record wildfires, and drastically changing wind and precipitation patterns all “alter the formation, duration and dispersion of air pollution,” notes a World Meteorological Organization bulletin, highlighting the synergistic health effects of global warming. The Global South, an epicenter of poor air quality, is being especially hard hit. A toxic soup of air pollutants — automotive exhaust fumes over urban India, choking dust clouds blowing across Nigeria, and suffocating wildfire smoke blanketing Brazil — are being made even deadlier by a rapidly destabilizing climate. Ozone over New Delhi The summer of 2024 in India’s capital, New Delhi, was more brutal than any Kunal Kumar can remember. The city was trapped under the longest heat wave in 13 years. Things were so bad that Kumar, a gig worker who makes food deliveries, was forced some days to give up his outdoor income. “Better to lose my wages and stay at home than die of a heatstroke,” he told Mongabay. Delhi, a sprawling city in northern India, is nestled in the country’s Indo-Gangetic Plain where summer daytime temperatures average 32°C (90°F). But a series of persistent anticyclonic wind circulation events over the northern Indian Ocean, coupled with the fading El Niño, caused clockwise wind gusts to sink over the city, creating a persistent high-pressure heat dome that pushed 2024 temperatures to relentless highs. For weeks, brutal daytime temperatures stayed above 40°C (104°F), with little respite by night. The city’s solar heat-absorbing built environment made conditions even more miserable and dangerous. For Kumar, who spends 12 to 15 hours a day on the road making deliveries, the heat was life-threatening — as it was for the rest of the city’s 33.8 million people, many of whom work outside or lack air-conditioning. In Kumar’s cramped South Delhi neighborhood, heat radiated off the walls and street day and night in a textbook example of the urban heat island effect. He was dehydrated and irritable most days. “Everywhere you look there’s a traffic jam in this city. Stuck in jams, under the hot sun with hot air blowing on your body; it was unbearable,” Kumar remembers. Normally, air pollution is perceived as a winter problem in Delhi, when a thick blanket of low-altitude smog gets trapped by cool air hanging above the metropolis. That smog is mostly composed of toxic PM2.5 particulates — very tiny particles that lodge in the lungs and can cause cardiovascular and respiratory disease. Every winter, PM2.5 levels peak due to seasonal crop burning and the exploding of fireworks during the Diwali festival, turning Delhi into one of the world’s most polluted places. But now, as global warming and urban development bring higher temperatures over the city in summer, the co-occurring impacts of intense heat and air pollution compound in less obvious but seriously unhealthful ways. In hot summer months, the traffic jams Kumar and thousands of gig workers are stalled in every day become hotspots for toxins that include PM2.5 particulates and ground-level ozone. High up in the stratosphere, ozone plays a vital beneficial role, absorbing the sun’s harmful ultraviolet rays. But close to Earth’s surface, it’s a potent air pollutant whose insidious health impacts accrue in the body. Ground-level ozone is formed when nitrogen oxides and volatile organic compounds (VOCs), emitted from vehicle exhausts and other combustion sources such as factories, react with sunlight. A recent analysis by the Centre for Science and Environment (CSE), a Delhi-based think tank, found that new hotspots for ground-level ozone emerged across the city over the summer. Between April and July 2024, Delhi recorded ground-level ozone readings in excess of safe limits on 102 days, often for more than 13 hours at a stretch, the analysis said. Annual PM2.5 background levels have also risen steadily, driven predominantly by an increase in transportation emissions — traffic that now worsens air pollution in winter and drives ground-level ozone in summer. Epidemiologist Poornima Prabhakaran, director of the Centre for Health Analytics Research and Trends at Ashoka University, calls the increasing ground-level ozone trend worrying. India has the highest death burden of any nation from chronic obstructive pulmonary disease, attributable to ground-level ozone levels, according to the “State of Global Air” report published annually by U.S.-based Health Effects Institute in partnership with UNICEF; ozone killed 238,000 people in India in 2019. People also continue breathing other toxic contaminants released from tailpipes and smokestacks. But “The impacts of [these] secondary pollutants have not been given as much attention compared to the impacts of smog and PM2.5, probably because of lack of awareness,” Prabhakaran said. Prabhakaran is working with scientists internationally, developing databases to track the impacts of air pollution (including PM2.5 and ozone) on a variety of outcomes, such as respiratory and cognitive health functions. “We’re trying to analyze, with data, every health outcome that we can get our hands on,” Prabhakaran said, adding, “Intermediate risk factors like hypertension, high blood pressure, fasting glucose, high lipid levels — all of those cardiovascular outcomes — are known to worsen with even chronic, low-dose [air pollution] exposure.”

Unfair to blame Haryana & Punjab farmers for Delhi’s severe pollution: Ashok Khemka

Additional chief secretary Ashok Khemka has defended farmers in a note to CM Nayab Singh Saini and chief secretary Vivek Joshi, saying that while burning ‘parali' (paddy residue) negatively affects air quality and should be stopped, it is unfair to hold crop growers of Punjab and Haryana responsible for Delhi's severe air pollution. The senior IAS officer, who is ACS transport, referred to a video conference of Jan 4 under the chairmanship of the PM's advisor, Tarun Kapoor, in which the chairman of Commission for Air Quality Management (CAQM) made a presentation on the subject. The presentation was based on a Jan 2023 report by The Energy and Resources Institute (TERI), which said agricultural residue burning contributes 1% to PM 2.5 and PM10 levels in Delhi. This finding was displayed in a slide labeled ‘Sectoral Contribution of Sources of NCR to Particulate Matter'. Khemka's note, titled ‘Management of Air Pollution in NCR', was sent on Jan 10. According to the TERI report Khemka referred to, road dust contributes 42% to PM10 levels in Delhi annually while transport contributes 25%. Transport accounts for 47% of PM 2.5 emissions and road dust 20%. There is a higher contribution of dust sources to PM10 in summer (38-42%) compared to winter (23-31%). It's the same for PM 2.5 (31-34% in summer to 15% in winter). Why annual data doesn't give a clear picture However, while the ACS stresses the importance of having a strategy to contain vehicular pollution, farm fire emissions cannot be compared to vehicular or any other pollution source that is an all-year phenomenon. Farm fires are seasonal, happening within a window between Sept 1 and Nov 30. So, their share in an annual metric will always be small. Besides, during the peak season for farm fires, their share in the capital's pollution levels are much, much higher than 1%. According to the Decision Support System (DSS) for air quality management in Delhi, which has been used to monitor the contribution of farm fires to the capital's PM 2.5 levels, stubble burning's contribution touched 35% on Nov 1 last year. Every winter, air quality in Delhi-NCR plummets to hazardous levels as the airshed fills up with toxic haze which is triggered by a combination of pollutants, fog, lack of winds and other meteorological factors. Farm fires, commonly seen in north India's agricultural belt to clear tracts of land for another round of sowing after the paddy harvest, become a major compounding factor when added to local sources. Shubhansh Tiwari, research associate at Centre for Science and Environment (CSE), told TOI: "Agricultural residue burning's overall contribution is small compared to other sources as it occurs for a limited period. The issue needs to be addressed because, during the 45 days when farmers clear their fields, meteorological conditions carry the smoke into NCR. Nevertheless, road dust and vehicular emissions remain primary contributors to particulate matter in Delhi-NCR and effective management of these sources, especially during the summer months when dust levels are higher, is crucial for improving air quality. So what we need is a holistic approach that addresses all significant pollution sources."

Air pollution may contribute to almost a quarter of deaths in India

Particulate pollution is killing millions more people in India every year than previously thought, a new study reveals. This type of pollution could potentially be responsible for almost a quarter of deaths in the country. The research focuses on the health effects of particles smaller than 2.5µm in diameter – PM2.5. The researchers examined the link between PM2.5 particles and mortality between 2009 and 2019 in 655 out of 787 districts of India and found every person in the country was exposed to high levels of this type of pollution. The study highlights that the entire population of India is currently exposed to PM2.5 levels that exceed those recommended by the World Health Organization (WHO). According to the WHO, the annual average PM 2.5 concentration should not exceed 5µg/m3 and the 24-hour average exposure should not exceed 15µg/m3. In several Indian regions annual average PM2.5 levels reached 119µg/m3 – much higher than both Indian and WHO recommended safe limits. The international team of researchers found that every 10µg/m3 increase in annual average PM2.5 led to an 8.6% increase in mortality. The results show that around 3.8 million deaths, amounting to 5% of total mortality over the period, can be linked to air pollution levels above India’s own PM2.5 guidelines of 40µg/m3, which are themselves eight times higher than the WHO’s. When compared with the much more stringent WHO guidelines of 5µg/m3, 16.6 million deaths annually could be attributed to air pollution – almost 25% of all mortality during the study period. In contrast, a comprehensive global study of disease burden in 2019 attributed just under 1 million deaths to air pollution in India. ‘The results show that current guidelines in India are not sufficient to protect health. Stricter regulations and measures to reduce emissions are of utmost importance,’ said Petter Ljungman, co-author and researcher at the Institute of Environmental Medicine at the Karolinska Institute. ‘Our study provides evidence that can be used to create better air quality policies, both in India and globally.’ The Centre for Science and Environment (CSE) in India recently released its annual assessment and reported that ‘the annual PM2.5 concentration [in Delhi] has increased to 104.7µg/m³ in 2024 – a 3.4% rise from 2023 and this is more than twice the national ambient air quality standard of 40µg/m³’. The citywide winter air pollution peak for 2024 soared to 732μg/m³, 26% higher than last year’s peak of 580μg/m³. ‘This cannot be seen as an annual aberration due to meteorological factors and the consistent rise indicates the impact of growing pollution in the region,’ says Anumita Roychowdhury, executive director, research and advocacy at CSE. Traditionally, burning of farm stubble residues has been blamed for PM2.5 pollution in north India but the CSE analysis indicates that there has been a very significant decline in stubble fires in recent years. In 2024, the total annual fire counts in Delhi, Punjab and Haryana declined 37.5%. Punjab, a significant contributor to fire events, recorded a substantial 75% decline during October–December 2024. The trends show much deeper systemic change is required to cut year round emissions from traffic, industry, burning of waste and biomass, construction, solid fuels for cooking and dust sources in Delhi and the surrounding region, says the CSE.

A gentle giant

Our association was uncommon — even unusual. Dr Manmohan Singh, India’s economist prime minister who passed away recently, was cut from the conventional cloth of market economics. Anil Agarwal was a dyed-in-the-wool environmentalist. In 1991, when Manmohan Singh brought India into the liberalised world of de-regulation and opened borders for trade, we were not part of the cheering brigade. For us, the issue was what liberalisation would mean for the environment — our regulatory institutions were fragile and so, would this opening of the economy lead to pollution and degradation? But interestingly, we were not dismissed by Singh, and this is what made him different from his ilk. He engaged with us. This is not to say that he accepted what we said. But he understood that this was a world that he had not considered. He wanted to know more; wanted to understand what could be done to strengthen the systems so that a balance could be found. ‘Balance’ was the operative word. In the mid-1990s, when Anil started the first environmental rating programme for industry, Manmohan Singh agreed to chair the advisory committee. This was our effort, not just to benchmark performance but also to use measuring indicators to push, prod towards business unusual. He did not fuss or flinch at our effort to demand more from industry than meeting regulatory standards. He understood the need for transformative action in a country like India, where natural resources needed for economic growth are scarce and pollution adds to costs that the poor cannot afford. In 2004 when Singh took over as India’s Prime Minister, Anil had tragically passed away and I was now heading the Centre for Science and Environment. I was much younger, much less experienced. But not once did Singh make me feel inadequate. He let me visit him in the Prime Minister’s office — he heard what I had to say on issues ranging from water conservation to climate change. He not only listened but egged me to provide solutions. “What needs to be done” — this was his focus. In 2005, he asked me to chair the committee to review tiger conservation. I was overwhelmed by his trust in me, given that the other committee members were doyens in the field or connected to the powerful conservation lobby of the country. It was a tough time as well. On the one hand, India had lost all tigers in the Sariska Tiger Reserve. So what should be done to repair the conservation agenda? On the other hand, this was also the time when the Forest Rights Act (FRA) was being discussed to restore the historical injustice to tribals so that they would get tenure over the land they inhabited. But this land was forests – and in some cases, also land under national parks and sanctuaries where tiger and other animals roamed. It was a clash of agenda; it was also a class war — conservation versus tribals. Singh, frankly, was caught in between: he respected both sides and did not want to choose one or the other. The balance of both interests is what he sought. I presented the report to Manmohan Singh a few days before the official presentation. I wanted him to understand the agenda for action – particularly the need for an inclusive paradigm of conservation. He understood the stakes and the resistance and asked if I was certain this could be done and if key stakeholders were on board. I told him that it was difficult but not impossible. My request was that the report, called Joining the Dots should be made public as this would build awareness about the agenda and also drive policy change. My fear was that it would be shelved — as is often the fate of many reports. It is to his credit that much action happened for the conservation of tigers; numbers are up and most importantly, we have better counting methods so that it is not pugmarks, but tigers that are being counted. Later, he made me a member of the Prime Minister’s Council on Climate Change and on cleaning Ganga. In all cases, I was never made to believe that I should not express my views, however different from the others in the room. In fact, my positions — as always to push the envelope — were encouraged by him, but with the caveat that the solutions had to be feasible. This is why Manmohan Singh and his particular brand of politics and persona will be missed in our world of extremes. Today, we live in bubbles where we read and hear only the opinions of people we agree with. We have no time for another’s view because it is not in consonance with our position and so irrelevant. Or because it does not fit into the formula of actions that we have been taught will work — the established book of rules. Dr Manmohan Singh also had his pre-proposed ideas; what was in the textbook or his experience. But he opened doors; because he had an openness of thought, driven by his commitment to change. He was a gentle giant that made power good. He used great power for great good. DTE The writer is the Director-General of CSE and editor of DownToEarth. Views expressed are personal

Planners Need to Keep Pace with Changes: Sarada Muraleedharan

In a scenario where changes are happening so fast civic planners need to be agile and keep pace with the changes and come out with sustainable solutions to address multiple challenges, said Sarada Muraleedharan, Chief Secretary, Government of Kerala, here today. She was addressing the valedictory session of the 73rd National Town and Country Planners Conference, organised by the Institute of Town Planners, India (ITPI), with the support of the Local Self Government Department here. The idea of planning needs to move beyond concepts to come to grip with real issues and formulate responses that work on the ground, she said, referring to multiple issues being faced by Kerala society including the waste management. While there is no dearth of master plans that seek to address each critical issue their real test is how effective they are on the ground, she said. Sarada Muraleedharan also distributed the National Best Thesis awards instituted by ITPI for post-graduate, under graduate and female students on the occasion. ITPI president N K Patel, Rajesh PN, Chairman ITPI, Kerala Regional Chapter, Pradeep Kapoor, Coordinator (Techno Admin) ITPI, and Anoop Kumar Srivastava, Vice President ITPI also spoke. The meet, whose focal theme was “Intelligent, Digital Spatial Planning and Governance’, covered a range of live topics relating to urban and country development including technological advancements. Meanwhile, in a technical session on ‘Blue-Green Economy for Resilient Future,’ experts noted that extreme heat affects productivity imposes stress on urban infrastructure and they called for adopting a climate-sensitive urban design for the country and ramping up the heat management policy. Rajneesh Sareen, Programme Director, Sustainable Habitat Programme, CSE, New Delhi, said Indian cities should adopt heat-resilient urban planning and design, integrating green-blue infrastructure and nature-based solutions. Anumita Roychowdhury, Executive Director, CSE, New Delhi; Dr Banhi, Chakraborty, Ex-Faculty, Dept. of Architecture and Planning, IIT Kharagpur; and Dr Reshma Vilasan, Assistant Professor, Nitte School of Architecture, Planning & Design, Bengaluru, also spoke. In another session on ‘Techno-Urbanism,’ VK Paul, Director, School of Planning and Architecture, said it’s the responsibility of the planners to use all the spatial data available to rejuvenate public spaces through designs that comply with human sensibilities. N Sridharan, Former Director, School of Planning and Architecture, Bhopal, planners should address the issue of digital divide across socio economic classes, ages, sex and region while designing spatial governance. KV Abdul Malik, Chief Town planner (Vigilance), Kerala, said data analysis is important for planning. VK Phatak, Former Principal Chief, (Planning Division), MMRDA and Dean Faculty of Planning, CEPT, also attended. In a session on ‘Local Democracy and Spatial Planning in Kerala,’ S M Vijayanand, Former Chief Secretary and Chairperson, Sixth State Finance Commission, Govt. of Kerala, said it is important to strive for a spatial planning where every citizen has the ‘right to city’. Shiji E Chandran, Chief Town Planner, LSGD (Planning), Govt. of Kerala; Jacob Easow, Former Additional Chief Town Planner, Kerala; Dr Ajith Kaliyath, Urban Chair Professor, KILA; Dr Mohammed Firoz, Associate Professor, NIT Calicut; Baiju K, Senior Town Planner (Retd.), Kerala; and Uday Chander, Dy Director, MSRDC, Mumbai, also spoke. ITPI is the premier institution of qualified urban planners in the country, promoting dynamic, inclusive and integrated town and country planning practice, education, research and institutional mechanism for vibrant, sustainable and resilient spatio-economic development of towns, cities and regions.

Time to recalibrate PM-Kusum scheme

The success of Central or State government scheme is judged by their results. Stories of Devki Devi and Sunita Devi, now known as “Solar Didis” from Bihar, are examples. But, it also a reflection of the State’s political economy as well as Centre-State relations. The Pradhan Mantri Kisan Urja Suraksha Evam Utthaan Mahabhiyan (PM-Kusum) Scheme was launched in March 2019 and scaled up last in September 2023 to provide affordable and accessible power to the farmers throughout the country. The main objectives of the scheme was to wean the farm sector from diesel, to provide energy and water security to farmers, enhance their income, and reduce environmental pollution. The scheme has three components: Component ‘A’: Setting up of 10,000 MW of decentralised ground/stilt mounted grid connected solar or other renewable energy based power plants by the farmers on their land; Component ‘B’: Installation of 14 lakh standalone off-grid solar water pumps; Component ‘C’: ‘Solarisation’ of 35 lakh existing grid-connected agriculture pumps and through feeder level solarization (FLS). All three components of the scheme aim to add solar capacity of about 34,800 MW by March 2026 with the total Central financial support of ₹34,422 crore. The story of Solar Didis is what Component C is all about. But, Deviki Devi and Sunita Devi have been beneficiaries of Aga Khan Rural Support Programme (India) and the local government programme, as Bihar didn’t adopt the PM-Kusum Scheme. The State did not want to provide individual solar irrigation projects, and started to solarise the electric grid. Another reason for Bihar not adopting it was that earlier the parties that ruled the State and Centre were not allies. But now things may change. Implementation challenges ‘Implementation Challenges of the PM-Kusum Scheme: Case Studies from selected Indian States’, a report brought out by The Centre for Science and Environment in 2024, pointed out the challenges of the PM-Kusum Scheme and the reason for its slow progress. According to the report, while Component B of the Scheme has seen significant progress, particularly in Haryana, Rajasthan, Maharashtra and Uttar Pradesh, Components A and C have been falling behind. Most implementation efforts have focused on replacing diesel pumps with solar variants, which has brought substantial benefits to farmers. The report had pointed out that a major hurdle was availability of cheap electricity for the farmers which waters down the incentive to switch to solar pumps. It also pointed towards centralisation of the implementing model. It called for decentralisation of the scheme’s implementation; simply put, making use of the field knowledge of local implementing agencies. The report also recommended offering farmers payment options as well as increase in Central assistance. According to the report, the Scheme holds the potential to reduce carbon emissions by 5.2 million tonnes, making its successful implementation crucial for India’s climate action efforts. The data available at the PM-Kusum portal show that as on September 30, 2024, under Component A, total sanctioned Solar Capacity was 9,110 MW and the total installed Solar Capacity was 298.83 MW. Under Component B as on September 30, 2024, total sanctioned standalone pumps were 13,42,327, and total installed standalone pumps were 4,99,319. For Component C as on September 30, 2024, total pump sanctioned for individual pump Solar were 1,71,640, total pump solarised under installed Individual pump solar were 4,759. Total pumps sanctioned for feeder level solar were 33,85,494 and total pumps solarised under feeder level solar were 32,512. Tardy progress Clearly the progress has not been up to the mark and to meet the target some rethinking is required. “For A the progress has been minimal mainly since most of the RE nodal agencies have not promulgated bidding guidelines, there is also no subsidy available under this, the RE agencies which have released guidelines quote feed in tariffs in ₹3-3.30/kwh, which is low without subsidy,” said Arvind Poswal, Programme Officer, Renewable Energy, Centre for Science and Environment. Component B has seen most success since the Central Financial Assistance is almost 60 per cent, also states/regions with concerns on ground water use, irrigation related challenges have witnessed deployment, he said adding that the decentralized approach undertaken by some States has also improved deployment, e.g. Rajasthan where the horticulture department is nodal agency for it. “Wide awareness campaigns by the nodal agencies etc has worked. However, there have been concerns regarding the quality of pumpsets etc,” he added. Under component C, States such as Maharashtra, Uttar Pradesh and Rajasthan have released guidelines and witnessed traction in deployment. “Since for PM-Kusum we also must examine political economy issues such as subsidies given to the farm sector and the need to offset them via day time solar based power. In other States the progress has been slow. Since the Ministry for New and Renewable Energy has published several implementation guidelines, States must come forward to identify their roadblocks and fasttrack deployment based on their unique individual constraints and see this as an opportunity towards reduction of subsidies for irrigation related electricity subsidies,” he said. The scheme must be seen as an extension towards developing the farm/agriculture sector, the Component A and C can be leveraged towards creating solar based electricity generation via models such as Agro-PV which utilise energy generation and farming in a dual use model, Poswal added. To make it a success and achieve its objectives both the Centre and the States have to work in sync while recalibrating the process of implementation.

Stubble Burning: दिल्ली के वायु प्रदूषण में पराली का योगदान सिर्फ एक फीसदी, अफसर ने कहा दोषी नहीं किसान

आमतौर पर हर साल धान की कटाई के दौरान दिल्ली-एनसीआर इलाके में वायु प्रदुषण एक गंभीर समस्या का रूप लेता है। इस बार भी ऐसा हुआ सुप्रीम कोर्ट ने परली जलने की घटनाओं को रोकने के लिए राज्य सरकारों को आदेश दिए। वहीं, राज्य सरकारों ने परली नहीं जलने के लिए किसानों पर जुर्माने से लेकर पराली नहीं जलने पर प्रोत्साहन योजनाएं भी लांच की थी। लेकिन, वायु गुणवत्ता प्रबंधन आयोग ने प्रधानमंत्री कार्यालय को बताया है कि दिल्ली के प्रदुषण स्तर में पराली जलाने की घटनाएं केवल 1 फीसदी का योगदान देती हैं। इस पर हरियाणा के अतिरिक्त मुख्य सचिव (परिवहन) अशोक खेमका ने कहा कि राजधानी दिल्ली में बिगड़ती वायु गुणवत्ता के लिए पंजाब और हरियाणा के किसानों को जिम्मेदार नहीं ठहराया जा सकता है। नोट में सीएक्यूएम के अध्यक्ष द्वारा ऊर्जा और संसाधन संस्थान (टेरी) की जनवरी 2023 की रिपोर्ट पर भरोसा करने का हवाला दिया गया, जिसमें कहा गया था कि दिल्ली में पीएम 2.5 और पीएम 10 के स्तर में कृषि अवशेष जलाने से केवल 1% का योगदान है। खेमका ने कहा कि पराली जलाना स्थानीय वायु गुणवत्ता के लिए हानिकारक है और इसे रोका जाना चाहिए, लेकिन पंजाब और हरियाणा के किसानों को दिल्ली में खराब होती वायु गुणवत्ता के लिए दोषी नहीं ठहराया जा सकता। TERI की इस रिपोर्ट का हवाला देते हुए अधिकारियों ने बताया कि सड़क और खुले क्षेत्र की धूल खराब वायु गुणवत्ता में महत्वपूर्ण योगदान देती है। गर्मियों में PM10 में धूल का योगदान 38 से 42 फीसदी और सर्दियों में 23 से 31 फीसदी होता है, जबकि PM 2.5 में इसका योगदान गर्मियों में 31 से 34 फीसदी और सर्दियों में 15 फीसदी होता है। वहीं, गर्मी के सीजन में शुष्क मौसम इस समस्या को और बढ़ा देती हैं। कृषि विशेषज्ञ देविंदर शर्मा ने भारतीय उष्णकटिबंधीय मौसम विज्ञान संस्थान, पुणे के एक अध्ययन का हवाला दिया, जिसमें पाया गया था कि दिल्ली के प्रदूषण में पराली जलाने की भूमिका मात्र 1.3 फीसदी है। वहीं, वाहनों का योगदान प्रदुषण में 14.2 फीसदी प्रदूषण होता है, उसके बाद निर्माण गतिविधि और धूल का स्थान प्रदुषण के कारक बनते हैं। पराली जलाने में कमी आने के बाद दिल्ली का सालाना PM2.5 स्तर 2024 में लगातार दूसरे वर्ष बढ़ा। सेंटर फॉर साइंस एंड एनवायरनमेंट (CSE) की रिपोर्ट के अनुसार, दिल्ली का वार्षिक PM2.5 स्तर 3.4 फीसदी बढ़कर 104.7 माइक्रोग्राम प्रति क्यूबिक मीटर हो गया। प्रदुषण का यह स्तर स्वीकार्य राष्ट्रीय वार्षिक मानक से दोगुना से भी अधिक है। यह बढ़ोतरी अक्तूबर से दिसंबर 2024 के दौरान पंजाब, हरियाणा और दिल्ली में पराली जलाने की घटनाओं में 71.2 फीसदी की गिरावट के बावजूद हुई। हरियाणा के कृषि और किसान कल्याण मंत्री श्याम सिंह राणा ने कहा कि सरकार पराली जलाने से दूरी बनाने वाले किसानों के लिए प्रोत्साहन योजना बना रही है। वर्तमान में। वर्तमान में हरियाणा परली के प्रबंधन के लिए प्रति एकड़ एक हजार रुपये देता है। अधिकारियों का मानना है कि इस पहल की वजह से 2023 की तुलना में पराली जलाने की घटनाओं में 47 फीसदी की कमी आई है

Real-world impact of master plans vital

Thiruvananthapuram: In today's rapidly evolving landscape, civic planners must remain agile, adapt to changes, and devise sustainable solutions to address multiple challenges, said Sarada Muraleedharan, chief secretary. She was speaking at the valedictory session of the 73rd National Town and Country Planners Conference, organized by the Institute of Town Planners, India (ITPI), with the support of the local self-govt department. Sarada stressed the need for planning to move beyond theoretical concepts and tackle real-world issues with actionable solutions. Referring to challenges like waste management, she pointed out that while numerous master plans aim to address critical issues, their true test lies in how effectively they perform on the ground. As part of the event, Sarada presented the National Best Thesis Awards, instituted by ITPI, to post-graduate, undergraduate, and female students. The conference, which focused on the theme "Intelligent, Digital Spatial Planning and Governance," discussed a variety of topics related to urban and rural development, including the integration of technological advancements. During a technical session on "Blue-Green Economy for a Resilient Future," experts noted the impact of extreme heat on productivity and urban infrastructure. They called for climate-sensitive urban design and improved heat management policies. Rajneesh Sareen, programme director of the Sustainable Habitat Programme at CSE, New Delhi, urged Indian cities to adopt heat-resilient urban planning by integrating green-blue infrastructure and nature-based solutions.

Sunita Narain interview: ‘Trump’s victory poses a threat to the environment’

Environmentalist Sunita Narain on her book, The Rise of the Neo-Locals, the end of globalisation, climate change, and why new forms of localisation are not undesirable Leading environmentalist and Director-General Centre for Science and Environment, Sunita Narain’s latest nonction book, The Rise of the Neo-Locals: A Generational Reversal of Globalisation (CSE) is thought-provoking and an essential read for our times. With the question of whether globalisation is dead dominating discussions over the last few years —especially amid the rise of centre-right politics — Narain explores this topic against the backdrop of global challenges. She explores how the climate emergency, ongoing wars — Russia’s invasion of Ukraine and the genocide in Gaza — the marginalisation of the poor and even the anger of the rich are shaping global futures. Narain interweaves her personal journey — as an activist, researcher and writer — of being witness to both the rise of globalisation and its fall in post-colonial times. She observes that we are currently experiencing the birth of deglobalisation and re-globalisation, where countries will chart their own course. The book is written in a style that resonates with every kind of reader, but in particular for youth seeking to understand global movements and declared that the 1960s would be the Decade of Development. John F Kennedy said: “To those people in the huts and villages of half the globe struggling to break the bonds of mass misery, we pledge our best efforts to help them help themselves” and that most of these ‘huts’ and ‘villages’ were in India, which had already experienced the consequences of globalisation and capitalism during the colonial era; they became places of tension between localisation and globalisation. Then came the Liberalisation of the 1990s; the setting up of the World Trade Organization (WTO), ushered in an era of free trade. In this conversation with The Federal, Narain talks about the reasons behind writing the book, what lies ahead for global politics and economics, what should be anticipated with Donald Trump coming to power, and what is being done at the local level to counter climate change: Edited excerpts from the interview: What were the motivations behind writing this book? The book is a compilation of some of my writings of my experiences of the many years of being an activist and researcher. It is a subject I keep coming back to: The tensions between insular tendencies of society and the broader consequences of globalisation. I am a child of de-globalisation. I have seen the world move from deglobalisation to an era dominated by free trade. Over time, I have seen how this shift has impacted the world.

Opinion: Protecting planet’s protective shield

Over two billion years ago, blue-green algae — early aquatic organisms — began using energy from the sun to convert molecules of water and carbon dioxide and recombine them into organic compounds and molecular oxygen. This resulted in an increase in oxygen and a decrease in carbon dioxide in the atmosphere. Some oxygen molecules absorb energy from the sun’s ultraviolet (UV) rays and split to form single oxygen atoms. These atoms combine with molecular oxygen to form ozone molecules, which are very effective in absorbing ultraviolet rays. Ozone was discovered in 1785 by Dutch physicist MV Marum but it was only in 1840 that German chemist CF Schenbein could synthesise it. The ozone layer is not really a layer but has become known as such because most ozone particles are scattered between 19 km and 30 km up in the stratosphere in the form of a thick sheet called ozonosphere. Ozone also occurs in very small amounts in the lowest few kilometres of the stratosphere — the troposphere. The ozone layer can absorb 97-99 per cent of harmful ultraviolet radiations that the sun emits which can produce long-term devastating effects on human beings as well as plants and animals. Different Layers There are two layers of ozone in the atmosphere: bad ozone exists in the troposphere from ground level up to 10 km and is harmful to breathe. After the 10 km stratosphere, we have a good ozone layer extending upward up to 30 km and protecting life on Earth from the sun’s harmful UV rays. The bad ozone layer is created by chemical reactions between oxides of nitrogen and volatile organic compounds in the presence of sunlight. Ground-level ozone is a harmful pollutant. The good ozone layer is produced naturally in the stratosphere by UV rays reacting with oxygen. The Centre for Science and Environment has revealed a disturbing trend in ground-level ozone pollution rise across India’s major cities like Delhi, Bengaluru, Jaipur and Kolkata However, this good ozone has gradually been destroyed by human-made chemicals referred to as ozone-depleting substances (ODS), including chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, methyl bromide, carbon tetrachloride and methyl chloroform. These substances are being used in coolants, foaming agents, fire extinguishers, solvents, pesticides and aerosol propellants. They are broken down by the sun’s UV rays and release chlorine and bromine molecules, which destroy the good ozone. Scientists estimate that one chlorine atom can destroy 1,00,000 ozone molecules. Ozone Hole It is an area in the stratosphere where ozone depletion is so severe that levels fall below 200 Dobson Unit (DU) — the traditional measure of stratospheric ozone. Normal ozone concentration is 300-350 DU. Scientists say ozone-destroying substances (ODS) — mostly chlorine and bromine from CFCs and halon — are responsible for ozone depletion, to the extent of 1 per cent per day. Satellite data from NASA confirmed that the hole covered the entire Antarctic. The formation of ozone holes is irregular over the entire earth. For instance, the stratospheric circulation is much irregular in the Arctic region and the Arctic ozone layer is not as cold as that of the Antarctic, hence deep ozone hole is unlikely over the North Pole. According to the head of the National Ozone Centre in New Delhi, there is no trend to show total ozone depletion in the stratosphere over India. However, the Centre for Science and Environment, New Delhi, revealed a disturbing trend in ground-level ozone pollution rise across India’s major cities like Delhi, Bengaluru, Jaipur and Kolkata. Effects of Ozone Depletion • Human and animal health: Exposure to ultraviolet radiation (UVR) to the skin causes sunburn, and skin cancer — also in animals — and to eyes, causing damage to cornea and cataracts. • Terrestrial ecosystems: In forests and grasslands, UVR exposure results in mutation thus altering the biodiversity in different ecosystems. • Aquatic ecosystems: The coastal zones are more sensitive to UVR than those living in offshore that are adapted to higher levels of radiation. UVR can cause damage to the early development stages of fish, shrimp, crabs, amphibians and other animals, the worst effect being decreased reproductive capacity and impaired larval development. • Effect on materials: Increased levels of UVR have adverse effects on synthetic polymers, naturally occurring bio-polymers and some other materials of commercial interest. Montreal Protocol In a bid to contain ozone depletion, a landmark multilateral environmental agreement was formulated that regulates the production and consumption of ODS. ODS when released into the atmosphere change the stratospheric ozone layer — the earth’s protective shield that protects humans and the environment from harmful levels of UVR from the sun. Adopted on 16 September 1987 and celebrated as International Day for Preservation of Ozone Layer, the Montreal Protocol is a rare treaty to achieve universal ratification. The parties to this reached an agreement on 15 October 2016 in Kigali, Rwanda, to phase down HFCs. The Montreal Protocol is saving about two million people each year by 2030 from skin cancer. The parties to the protocol have phased out 98 per cent of ODS globally compared with 1990 levels. Under the Kigali Amendment, the use of HFCs is expected to prevent emissions of up to 105 billion tonnes of carbon dioxide equivalent to GHGs, helping avoid up to 0.5 degrees Celsius of global temperature by 2100. Solutions and Recovery The entire planet is vulnerable to the effects and consequences due to ozone depletion. Solutions include ODS like CFCs and halons should be avoided; eco-friendly pesticides should be used; nitrous oxide should be prohibited; natural and eco-friendly cleaning products should be used in the household apart from non-toxic products like vinegar and bicarbonate. As per the guidelines of the Montreal Protocol and subsequent amendments, the consumption of ODS fell by 90-95 per cent till 2005. The size of the Antarctic ozone hole reached 29.9 million square kilometres in 2000. By 2021, the area shrunk to 24.8 million square kilometres. A few years ago, a United Nations report estimated that the Antarctic ozone hole would close slowly and the stratospheric ozone concentrations would return to 1980 values by 2060 and that of Arctic, ozone levels are expected to return to 1980 values by the mid-2030s. Ensuring the protection of the ozone layer must be our long-term commitment and responsibility. The whole of humanity around the world and each generation must take up the baton to ensure the continued survival of our planet’s protective shield. Teaching the next generation about the Montreal Protocol empowers them with the knowledge that environmental challenges can be overcome if we listen to science and work together.

जमीनी हकीकत: भविष्य की ओर बढ़ने से पहले पीछे मुड़कर देखें

वर्ष 2024 को ऐसे साल के रूप में याद किया जाएगा, जिसमें दुनिया कई मायनों में बदल गई। ऐसा कोई दिन नहीं गुजरा, जब दुनिया का कोई न कोई हिस्सा मौसम की अति का शिकार नहीं हुआ। इन विकट परिस्थितियों में गर्मी और ठंड के नए रिकॉर्ड बने और कुछ दिन के भीतर फिर टूट गए। पहले ही अपने अस्तित्व की लड़ाई लड़ रहे समुदायों के लिए बार-बार आने वाली ऐसी प्राकृतिक आपदाओं से उबर पाना लगभग असंभव हो जाता है। वैज्ञानिक इसे ‘एंथ्रोपोसीन युग’ कहते हैं। ‘एंथ्रोपोसीन युग’ भूविज्ञान के शब्दों में वह समय है, जब मानवीय गतिविधियों का जलवायु और पारिस्थितिकी-तंत्र पर गंभीर असर पड़ता है। हमने मानवीय प्रगति (अच्छे रहन-सहन एवं धन सृजन के लिए) के लिए जो उपाय किए हैं उनके प्रभाव सभी देशों और दुनिया की सीमा से परे दिखने लगे हैं। यह अभूतपूर्व परिवर्तनों का दौर भी है – मनुष्यों के एक दूसरे के प्रति आचरण में बदलाव का, सही और गलत के वैश्विक नजरिये में बदलाव का और आर्टिफिशल इंटेलिजेंस (एआई) तकनीक की ताकत में बदलाव का। अगले कुछ साल में दुनिया की दशा और दिशा एआई की ताकत से ही तय होगी। हमने सार्वजनिक विमर्श का तरीका भी बदल दिया है। अब हम जो महसूस करते हैं, उसे कहने में बिल्कुल भी नहीं हिचकते भले ही वे अप्रिय, घृणा फैलाने वाली या विनाशकारी ही क्यों न हों। हम इसे अभिव्यक्ति की स्वतंत्रता लोकतंत्र की रक्षा का माध्यम समझने लगे हैं। मगर ऐसा करते-करते हम पूरी तरह नए युग की तकनीक पर आश्रित हो गए हैं। आज की बड़ी तकनीकी कंपनियों का लगभग सभी चीजों पर नियंत्रण हो गया है। इन कंपनियों का बढ़ता प्रभाव देशों की सीमाएं लांघकर दुनिया में सभी लोगों को अपनी जद में ले चुका है। इन कंपनियों ने अतीत की बहुराष्ट्रीय कंपनियों को बौना बना दिया है। तनिक विचार करें कि जिस तरह हम समाचार सुनते, देखते या पढ़ते हैं, जिस तरह हम खरीदारी करते हैं और जहां भी रहते हैं वहां हमारे जीवन का हरेक पहलू किस तरह इन कारोबारों का हिस्सा बन चुका है। अब इन भारी भरकम तकनीकी कंपनियों के मालिक न केवल तकनीक एवं मीडिया को मनमाने ढंग से बदल रहे हैं बल्कि राजनीति की दिशा भी तय करने लगे हैं। वे अपना प्रभाव बढ़ाना चाहते हैं और सरकारों के कमजोर होते ही वे और मजबूत हो जाते हैं। ज्यादातर सरकारें इस भ्रम में हैं कि वे ही नीतियां तय कर रही हैं और उनकी नीतियां लोकहित में हैं। सच्चाई यह है कि सरकारों ने अपना यह उत्तरदायित्व बड़ी कंपनियों, निवेश बैंकों और निजी कारोबारों को दे रखा है। सार्वजनिक गतिविधियों की गुंजाइश कम होती जा रही है और निजी इकाइयों का दबदबा बढ़ता जा रहा है। ऐसा नहीं है कि लोकतंत्र खत्म हो चुका है मगर यह जरूर है कि कारोबारों और उपभोक्ता वर्गों (आप और हम) की सांठगांठ के कारण यह बुनियादी तौर पर बदल चुका है। अब दुनिया अधिक असुरक्षित एवं बेचैन हो रही है क्योंकि हरेक संकट आने वाले दूसरे संकट की जमीन तैयार कर रहा है। हम तेजी से असमानता की शिकार हो रही ऐसी दुनिया में रहते हैं, जहां अमीर-गरीब की खाई बढ़ती जा रही है। इसके कारण और खराब व्यवस्था, जलवायु परिवर्तन के खतरों तथा संसाधनों की कमी के कारण लोगों का पलायन तेजी से बढ़ रहा है क्योंकि वे परेशान हैं और नए अवसर तलाशने की जद्दोजहद में लगे हुए हैं। इन सबके कारण लोगों में क्रोध और असुरक्षा की भावना भड़क रही है, जिससे नए कारोबारियों एवं महाशक्तियों के नियंत्रण वाली तकनीक के इस युग में लोकतंत्र तेजी से घृणा एवं ध्रुवीकरण का शिकार हो रहा है। यह गुस्सा गरीबों तक सीमित नहीं है। अमीर भी ठगा महसूस कर रहे हैं या कम से कम आज के हालात को इसी रूप में देख रहे हैं। 1990 के दशक में जब दुनिया भर की अर्थव्यवस्थाओं को एक दूसरे से जोड़ने की पहल हो रही थी तब सबसे अधिक डर गरीबों को सता रहा था। उन्हें लग रहा था कि उनका रोजगार छिन जाएगा। अब स्थिति उलटी हो गई है। पहले से अधिक संपन्न दुनिया में अब काम करने वाला तबका ही नई अर्थव्यवस्थाओं के लाभ से वंचित रह गया है। वे उनके खिलाफ खड़े हो रहे हैं, जिन्हें वे ‘शिक्षित अभिजात्य वर्ग और विशेषज्ञ’ कहते हैं और उनके हिसाब से जिन्हें सेवा और वित्तीय अर्थव्यवस्था के उदय का फायदा मिला है। इस वर्ग संघर्ष का सबसे खतरनाक परिणाम विचारों का तिरस्कार है। लोग ज्ञान को दोषयुक्त, पूर्वग्रह से भरा और निजी हितों को बढ़ावा देने का जरिया समझ रहे हैं। हमने दुनिया में सूचना और कारोबारी तंत्र का ताना-बाना जिस तरह खड़ा किया है यह सोच उसी का नतीजा है। हालत यह हो गई है कि जलवायु परिवर्तन से निपटने के उपायों जैसा जो कुछ जनहित में है, उसे भी संदेह की दृष्टि से देखा जाने लगा है। डॉनल्ड ट्रंप के दोबारा आने के बाद तो लोक कल्याण के विषय का भी मजाक उड़ाया जा रहा है। यह ऐसी स्थिति है जहां अर्थव्यवस्था, जलवायु परिवर्तन और राजनीति एक दूसरे के आमने-सामने खड़े हैं। जब दुनिया एक दूसरे से जुड़ी अर्थव्यवस्थाओं का ढांचा तैयार करने चली तो माना गया कि इससे संपन्न एवं सुरक्षित वैश्विक व्यवस्था का मार्ग प्रशस्त होगा। उम्मीद यह थी कि नई व्यवस्था में कोई देश दूसरे देश पर आक्रमण नहीं करेगा क्योंकि एक-दूसरे के साथ सहयोग उनके ही हित में होगा। मगर उद्योग दूसरे देशों में स्थानांतरित करने का असल कारण उद्देश्य श्रम और पर्यावरण सुरक्षा पर आ रही लागत कम करना था। ये लागत चुकाने पर विनिर्माण करना काफी महंगा साबित होता। इसका मतलब था कि उत्पादन जहां गया कार्बन उत्सर्जन भी वहीं पहुंच गया। कार्बन डाईऑक्साइड उत्सर्जन से जुड़े आंकड़ों के आधार पर हम कह सकते हैं कि चीन दुनिया में विनिर्माण का प्रमुख केंद्र बन गया है और दूसरे देश भी इसके साथ जुड़ने लगे हैं। दुनिया ऐसे पड़ाव पर खड़ी है जहां प्रदूषण रहित ऊर्जा तंत्र बढ़ाने की जरूरत महसूस हो रही है मगर नई वास्तविकताएं भी सामने खड़ी हैं। ‘दूसरी’ दुनिया खासकर चीन में पर्यावरण को अधिक नुकसान पहुंचाए बिना उत्पादन करना अब भी सस्ता है। ट्रंप ने उद्योग-धंधे अमेरिका में वापस लाने के लिए व्यापार युद्ध शुरू करने की धमकी दे दी है। मगर इससे वित्त एवं पर्यावरण सुरक्षा से जुड़े खर्च बढ़ जाएंगे क्योंकि दुनिया आपस में इस कदर जुड़ी और परस्पर निर्भर है कि देश आसानी से अलग नहीं हो सकते। व्यापार युद्ध कार्बन उत्सर्जन घटाने की मुहिम को भी नुकसान पहुंचाएगा क्योंकि यह सोच गहरा रही है कि पर्यावरण के अनुकूल वस्तु विदेश में बनी है तो उसे नकार देना चाहिए। जलवायु परिवर्तन के खतरे के बीच दुनिया एक अलग यथार्थ में पहुंच चुकी है। इसे ध्यान में रखते हुए हमें एक अलग भविष्य के लिए योजना तैयार करनी चाहिए। हम अतीत को पकड़क नहीं बैठ सकते। अपने युग की गलतियों को ध्यान में रखते हुए हमें नए सवेरे का पुरोधा और नए निश्चय का प्रतीक बनना होगा। ऐसा नहीं किया तो आने वाले दशकों में दुनिया बिखर जाएगी और जलवायु परिवर्तन से जुड़ी समस्याओं की आग में झुलस जाएगी। हमें हालात बदलने ही होंगे। (लेखिका सेंटर फॉर साइंस ऐंड एन्वॉयरन्मेंट से जुड़ी हैं)

Planners need to keep pace with changes: Kerala Chief Secretary

) In a scenario where changes are happening so fast civic planners need to be agile and keep pace with the changes and come out with sustainable solutions to address multiple challenges, said Ms Sarada Muraleedharan, Chief Secretary, Government of Kerala, here on Saturday. She was addressing the valedictory session of the 73rd National Town and Country Planners Conference, organised by the Institute of Town Planners, India (ITPI), with the support of the Local Self Government Department here. The idea of planning needs to move beyond concepts to come to grip with real issues and formulate responses that work on the ground, she said, referring to multiple issues being faced by Kerala society including the waste management. While there is no dearth of master plans that seek to address each critical issue their real test is how effective they are on the ground, she said. She also distributed the National Best Thesis awards instituted by ITPI for post-graduate, under graduate and female students on the occasion. ITPI president N K Patel, Rajesh PN, Chairman ITPI, Kerala Regional Chapter, Pradeep Kapoor, Coordinator (Techno Admin) ITPI, and Anoop Kumar Srivastava, Vice President ITPI also spoke. The meet, whose focal theme was “Intelligent, Digital Spatial Planning and Governance’, covered a range of live topics relating to urban and country development including technological advancements. Meanwhile, in a technical session on ‘Blue-Green Economy for Resilient Future,’ experts noted that extreme heat affects productivity imposes stress on urban infrastructure and they called for adopting a climate-sensitive urban design for the country and ramping up the heat management policy. Rajneesh Sareen, Programme Director, Sustainable Habitat Programme, CSE, New Delhi, said Indian cities should adopt heatresilient urban planning and design, integrating green-blue infrastructure and nature-based solutions. Ms Anumita Roychowdhury, Executive Director, CSE, New Delhi; Dr Banhi, Chakraborty, Ex-Faculty, Dept. of Architecture and Planning, IIT Kharagpur; and Dr Reshma Vilasan, Assistant Professor, Nitte School of Architecture, Planning & Design, Bengaluru, also spoke. In another session on ‘Techno-Urbanism,’ VK Paul, Director, School of Planning and Architecture, said it’s the responsibility of the planners to use all the spatial data available to rejuvenate public spaces through designs that comply with human sensibilities. N Sridharan, Former Director, School of Planning and Architecture, Bhopal, planners should address the issue of digital divide across socio economic classes, ages, sex and region while designing spatial governance. KV Abdul Malik, Chief Town planner (Vigilance), Kerala, said data analysis is important for planning. VK Phatak, Former Principal Chief, (Planning Division), MMRDA and Dean Faculty of Planning, CEPT, also attended. In a session on ‘Local Democracy and Spatial Planning in Kerala,’ S M Vijayanand, Former Chief Secretary and Chairperson, Sixth State Finance Commission, Govt. of Kerala, said it is important to strive for a spatial planning where every citizen has the ‘right to city’. Ms Shiji E Chandran, Chief Town Planner, LSGD (Planning), Govt. of Kerala; Jacob Easow, Former Additional Chief Town Planner, Kerala;

DeBriefed 10 January 2025: Los Angeles burns; Trump tilts at ‘windmills’; What cricket chirps reveal about rainforest change

This week California burning ‘MOST DESTRUCTIVE’: At least 10 people have been killed and more than 9,000 buildings have been gutted in wildfires “scorching communities” across Los Angeles, the Los Angeles Times reported in its latest update on Friday. There are multiple fires burning across LA county, including the 15,800-acre Palisades fire that CNN described as the “most destructive fire in LA history”. ​​ INFERNAL LA: LA’s firefighters are struggling with water supplies and are “unaccustomed to fighting multiple blazes at once”, BBC News reported. “There are not enough firefighters in all of LA County to address four separate fires of this magnitude,” LA county fire chief Anthony Marrone told the outlet. The Los Angeles Times said the fires have already caused at least $50bn in losses, which could also threaten hundreds of thousands of Californians who already struggle to “find and keep affordable homeowners insurance”. TINDERBOX CLIMATE: Many outlets examined the climate “drivers” of the wildfires. The Washington Post said the flames were fanned by a “life-threatening and destructive” windstorm. BBC News said that California’s decade-long drought and a four-inch decline in LA’s annual rainfall had left the region dry and so “particularly vulnerable” to the spread of fires. The Guardian cited research finding that climate change has caused a 172% increase in California’s burned area since the 1970s. Hello, goodbye CAN’T TOUCH THIS: US president Joe Biden announced a “permanent stop” to new oil and gas drilling across more than 625m acres of US coastal waters, thus protecting 20% of the seabed, the New York Times reported. While Biden called the move a “climate imperative”, the Guardian pointed out that the law does not explicitly allow presidents to “unilaterally reverse a drilling ban without going through Congress”. Alaska, meanwhile, sued the Biden administration over oil and gas drilling leases in the Arctic, Reuters said. TILTING AT WINDMILLS: In a “lengthy tirade against windpower”, US president-elect Donald Trump pledged that no wind farms will be constructed during his second term, threatening billions of dollars in planned projects, Bloomberg reported. Earlier in the week, Trump criticised the UK government’s energy policy, with a call to “open up” North Sea oil and gas production and “get rid of windmills”, Reuters reported. HYDROGEN BREAK: After “months of intense lobbying”, the Biden administration finalised rules that “offer billions of dollars in tax credits to companies that make hydrogen”, the New York Times reported. The rules include relaxed criteria for the “struggling sector” to claim tax credits, the Financial Times wrote. Around the world RECORD HEAT: Multiple climate datasets have confirmed that 2024 was Earth’s hottest year on record, with temperatures breaching 1.5C above pre-industrial levels for the first time, BBC News reported. Carbon Brief has all the details in its latest state of the climate” quarterly update. ADIEU, TRUDEAU: Justin Trudeau announced his resignation as Canada’s prime minister on Monday, ending a near-decade “of [the country’s] most climate-conscious federal government”, but with a “physically enduring legacy” of oil pipeline expansions, the Narwhal reported. MECCA FLOODS: Torrential, unseasonal rain lashed cities in Saudi Arabia on Wednesday, with the holy city of Mecca facing the “worst floods”, Down to Earth reported. WATER WOES: Last year, water-related disasters claimed more than 8,700 lives, drove 40 million people from their homes and caused $550bn in economic damage, according to the 2024 Global Water Monitor report covered by the Guardian. TAPS TURNED: Climate-induced sea level rise will “overwhelm” many of the world’s biggest oil ports, including Houston, Rotterdam and Ras Tanura, according to new analysis by cryosphere scientists who described the threat as “ironic”, the Guardian said. BANKS BOUNCED: Bloomberg reported that there are “zero” big Wall Street banks left in the Net-Zero Banking Alliance, after the biggest US bank JP Morgan quit the UN-backed climate coalition weeks before Trump assumed office. 10 days The time it took for the world’s richest 1% to “burn through” their 2025 “share” of the global “carbon budget” for keeping warming under 1.5C, according to new Oxfam analysis. Latest climate research Arctic marine heatwaves could intensify “on orders of magnitude” during the rest of this century under climate change, posing “major challenges for Arctic ecosystems”, according to new Nature Climate Change research using high-resolution climate models. A new study in Science estimated that building materials used in new construction could potentially store 16bn tonnes of CO2 every year. New research in Nature Cities found that high-income city dwellers in China were more likely to “order in” food during heatwaves, revealing the “transfer of heat exposure from consumers to delivery riders.” (For more, see Carbon Brief’s in-depth daily summaries of the top climate news stories on Monday, Tuesday, Wednesday, Thursday and Friday.) Captured The map above uses squares to illustrate 1,682 studies where communities are taking on-ground measures to adapt to climate change, from the islands of Tuvalu to the high mountains of Nepal. These studies were collated as part of the most comprehensive assessment to date of the scientific literature on climate adaptation. Carbon Brief has produced an interactive article based on the database that pulls out some of the key findings and explores global trends.

Carbon Brief has produced an interactive article based on the database that pulls out some of the key findings and explores global trends. Spotlight What listening to crickets reveals about rainforest change This week, Carbon Brief speaks to scientists studying what sounds from wildlife can reveal about change in an Indian rainforest. On Christmas night in Coorg (Kodagu) – prime coffee country in India’s Western Ghats biosphere – the rainforest was anything but silent. The night air – though drier than it should be this time of year – was charged with an electric score of cricks, chirps, trills, hisses, croaks, whoops and whistles. The Western Ghats is one of the “hottest hotspots” of biodiversity on Earth, hosting 325 globally threatened species. Coorg, on its eastern slopes, is a micro hotspot that receives more than 4000mm of rainfall on average and is the source of the Kaveri river, whose waters are bitterly disputed among the south Indian states seeing increasingly hotter summers and devastating floods. A short climb reveals physical scars of extreme weather: beyond thick canopies are hilltops bearing gashes from devastating landslides in 2018 that killed 20 people and displaced 18,000. To understand the less-visible impacts of climate and land-use change on non-human species in Coorg’s dense forests and plantations, sound has emerged as an important tool. Biodiversity symphony Bio-acoustics is the science of sounds produced by biological systems and what they react to. Prof Rohini Balakrishnan at the Indian Institute of Science described her work as a “bridge between symphony, cacophony and silence” and said that there are “signatures” of land degradation in sound that photographs cannot capture. She told Carbon Brief: “When we first came to the Western Ghats 20 years ago to try and actually figure out an entire acoustic community, most people thought we were completely crazy, because nobody had tried anything at that scale.” Those first years, she said, were “very, very hard” on her team, involving months of fieldwork in forests “full of poisonous snakes, gaur (Indian bison) and some density” of elephants. A hillside in Coorg (Kodagu) in southwest India. Credit: Aruna Chandrasekhar, Carbon Brief A hillside in Coorg (Kodagu) in southwest India. Credit: Aruna Chandrasekhar, Carbon Brief The “tech part”, however, has become significantly easier since, with machine learning and algorithmic approaches being trained to look at an entire soundscape and, possibly, to decide if a landscape is degrading. Balakrishnan said: “When we started, all we had were those little Sony Walkmans and bat detectors. There were no recorders that you could programme and leave outdoors. So it was painful: follow an insect, get a recording. You had to be there doing the recording.” For Dr Vijay Ramesh, a postdoctoral scientist at the K Lisa Yang Center for Conservation Bioacoustics at Cornell University in New York state, an ongoing question is whether biodiversity can fully return to degraded landscapes that are being actively restored. Acoustics have played an essential role in helping answer that question, with soundscapes failing to detect insects in many restored sites. “I don’t think we would have got that particular understanding of insects without using audio recorders, because these are all high frequencies we cannot hear,” Ramesh told Carbon Brief. Cutting through noise With so many species calling at the same time, isolating individual sounds in a complex noise environment can be a challenge. To Balakrishnan, the rainforest can sound like a Christmas party where “everybody’s screaming and you’re interested in one conversation, one person”. Rohini and her team spent 15 years working on the “cocktail-party effect”, eventually finding that “what sounds to us like a cacophony actually can be close to silence for an insect”. Anthropogenic sound often shows up in recordings: sirens still go off at dawn to signal the start of a morning shift for tea plantation workers. Pouring rain can serve as a major “masker” of sound. While evidence of climate change’s impacts “still needs more long-term monitoring”, Rohini worries about humanity’s ability to “ignore planetary alarm bells”. She concluded: “[M]echanised noise, traffic or construction…we sort of learn to filter them out, or we live in these artificial worlds we create by putting on headphones. And I feel, in the end, it takes away your ability to listen to your surroundings and to be influenced by it. “Listening really is a survival skill for our species, but it also gives joy, and I think we are losing that ability to focus on sounds around us and think and ask: ‘What does that mean?’” Watch, read, listen BLACK MARKET: Context News interviewed Nigeria’s illegal oil refiners risking everything to meet their energy needs amid soaring fuel prices in the country. POLYCRISIS NOW: Tim Sahay spoke to the Centre for Science and Environment about what to expect from climate policy in 2025 as the global “polycrisis” unfolds. OFF THE CHARTS: A long read in the Atlantic examined how “extreme events are taking scientists by surprise” and “outpacing” the predictions of even the “best” climate models.

Climate Change and Indian Youth

Climate Change and Indian Youth Large developing countries like India are heavily impacted by climate change. Living in India, I have firsthand experience of this. As a youth living in Delhi, I have experienced air pollution affecting my health, leading to asthma and changes in climate conditions affecting my overall quality of life. In the summer of 2024, the Delhi government in India announced the closure of schools and started holidays earlier than normal in order to avoid the growing heatwaves. In the winter of 2024, schools had to be shut down and adopt a hybrid model of teaching in the wake of the deteriorating air quality. In a survey conducted by the Centre for Science and Environment, 94% of Indian youth opined that their life has been impacted by climate change. Among the 1,931 youth who participated in the survey, 88 percent noted changes in their physical surroundings. Many highlighted issues ranging from disruption in education to school closures, less productivity, and outdoor activities affecting physical and mental health. These findings are important given the fact that India has the world's largest youth population, and their perspectives are important in our climate story. At the same time, I am also witnessing the climate discourse taking place in the country.

82 cities used less than 66% of NCAP funds in the last 5 years to combat pollution

If you’ve ever lived in north India during the winter and struggled to breathe, you’re likely familiar with the acronym NCAP – the National Clean Air Programme. Launched by the environment ministry, it sets clear air targets for 131 cities that are required to reduce particulate concentration in the air. The deadline to achieve 40 percent reduction is 2025-26. Eighty-two cities get funds for this directly under NCAP. The remaining – 42 cities and seven ‘urban agglomerations’ – get funds under the 15th Finance Commission. From 2019 to May this year, all 131 cities were allocated a total of Rs 10,566 crore through both sources. Newslaundry learned that the 82 cities funded by NCAP used Rs 1,092 crore out of the Rs 1,615.47 crore released in the last five years – about 66 percent. The cities of Delhi-NCR, where the AQI reached an astonishing 481 last month, used less than 40 percent. Only 55 cities out of 131 managed to reduce their PM10 concentration in the air by at least 20 percent. Delhi managed a reduction of just 14 percent. Underutilisation, misallocation In October, the NCAP implementation committee held a meeting online. According to the minutes of the meeting, 68 cities did not utilise 75 percent of the funds allocated to them. Noida, for example, used 11 percent of its total allocation of Rs 30.89 crore. Visakhapatnam used 14 percent and Anantpur 20 percent. Among metro cities, Bengaluru’s utilisation was lowest at 30 percent followed by Delhi (31 percent) and Pune (46 percent). Delhi also lay at the bottom of the table when it came to utilisation of funds by states and union territories. Only Gujarat utilised 100 percent of its funds, followed by Odisha at 93.55 percent and Chhattisgarh at 92.8 percent. Delhi shared space with Jammu & Kashmir (40 percent) and Meghalaya (44 percent). According to minutes of a meeting in September by the NCAP apex committee, 67 percent of funds is spent on dust mitigation measures like repairing roads, installing pavements, improving traffic junctions, sprinkling water, and mechanised sweeping of roads. As for other pollutants – 14 percent is spent on vehicular pollution, 11 percent on solid waste management and biomass burning, four percent on capacity building and monitoring, two percent on construction and demolition waste, and one percent each on industrial pollution, public outreach, and domestic fuel. But why the focus on dust mitigation over all else? The environment ministry said in August that this is because studies “indicate that dust from road, construction and demolition activities contribute maximum to the PM10 level in the cities”. Hence cities had “prioritised their actions based on the sources of pollution”. However, this should be taken in context of the fact that NCAP funding is based on performance, and performance is assessed on the basis of improvements in ambient PM10 levels. Earlier this year, a study by the Centre for Science and Environment pointed out that this deviates focus from PM2.5 pollution, which Indian Express described as “more lethal”. This point – on spending less on other vital components – was raised in the meeting of the NCAP implementation committee. According to the minutes, participants discussed 21 “irrelevant” activities that were funded despite having little or no direct connection with improving air quality. These included installing streetlights, beautification protocols, installing CCTV cameras at dumping sites, buying computers and software, and paying electricity bills at construction and destruction waste plants. Another curious point is that while NCAP seems to focus on PM10 levels to assess a city’s performance, it also ranks cities under a programme called Swachh Vayu Survekshan based on policy measures implemented to reduce air pollution. The study by the Centre for Science and Environment found that the two rankings don’t often correspond. For example, a city that scores under the Swachh Vayu Survekshan might perform very poorly for not improving PM10 levels. Anumita Roy Choudhury, the author of the study, told Newslaundry this needs to be addressed. “In the case of Delhi, its ranking is poor in terms of PM10 reduction. But its ranking under SVS is in the top nine. So there’s a huge gap between action taken and reduction of PM10. This gap needs to be addressed,” she said. Goals met? Not quite But here’s what the nation really wants to know. Even as a focus on PM10 is not quite effective, is the spending to bring down PM10 achieving its goal? Let’s take Delhi, which utilised 32 percent of Rs 42.69 crore released under NCAP over five years. This money was predominantly spent to procure 14 mechanical road sweepers, 28 water sprinklers, smog guns, and two pothole repair machines. The procurement of the sweepers and repair machines are still “in progress”. But the major source of PM10 pollution in Delhi is industrial, which is coal and fly ash, contributing to 37 percent of pollution in summer and 12 percent of pollution in winter. Biomass and waste burning contributes 25.43 percent, and road dust and construction soil 30 percent. Transport, in winter, contributes to 19 percent of PM10 pollution. (It should be noted that NCAP funds are intended to be spent for an entire year; not every city gives the breakup of pollution based on season.) Yet there seems to have been no spending by Delhi, across winter and summer under the fund, to mitigate industrial pollution. Next, take Navi Mumbai, also funded under the NCAP. Allocated Rs 9.42 crore over five years, it spent 92 percent of its funds on categories like mechanised road sweeping, water sprinkling, creating ‘green belts’, procuring e-buses, and public awareness – spending that predominantly targets dust and vehicles. Meanwhile, the environment ministry says Navi Mumbai’s PM10 pollution is due to road dust (28 percent), transport (16 percent), industry (16 percent), coal and fly ash (12 percent), waste burning (15 percent), and secondary aerosol (13 percent). And Navi Mumbai’s performance in reducing PM10 concentration is abysmal; in fact, the annual average PM10 concentration increased from 88 in 2017-18 to 98 in 2023-24. (Note that some cities, like Delhi, do not categorise coal/fly ash in a category separate from industrial pollution.) We also looked at Ludhiana, which utilised 90 percent of Rs 97.75 crore allocated under the NCAP. Most of this was spent on constructing end-to-end pavements on 114 km of roads, setting up green urban spaces, mechanised road sweeping, water sprinkling, collecting construction and destruction waste, and anti-smog guns. Here, more than 30 percent of PM10 concentration is caused by industrial pollution, across seasons. Ludhiana only managed to reduce its PM10 concentration by four percent. Baddi in Himachal Pradesh, which recorded “very poor” AQI in November, spent its NCAP funds on two things: constructing pucca roads and installing a Continuous Ambient Air Quality Monitoring System. It’s worth noting that 21-22 percent of its PM10 concentration is contributed by industry. Cities like Gwalior and Bhopal, where road dust accounts for a significant portion of PM10 emissions – 88 percent and 60 percent, respectively – failed to make substantial progress in reducing PM10 levels. PM10 concentration in Gwalior increased from 126 in 2017-18 to 136 in 2023-24; Bhopal’s increased from 112 to 113 in the same period. Gwalior spent Rs 82 crore of NCAP funds and Bhopal Rs 180 crore, but they’re at the bottom in terms of reducing PM10. Instead, both cities prioritised spending on road paving, building footpaths, municipal waste processing plants, construction and demolition processing plants, parks, urban forests, public awareness, and installing e-vehicle charging points.
