ORGANIC TAKEOVER: HOW 10,000 FARMERS OF TELANGANA, ANDHRA ARE STEERING A SILENT MOVEMENT

-Down to Earth A federation of farmer-producer organisations has tapped into the growing organic market to help members raise incomes Catering directly to the consumers’ needs assures better marketability and incomes. This is what nearly 10,000 farmers of Telangana and Andhra Pradesh have realised over the past decade and are now steering a silent organic movement. It all began in 2009, when a group of consumers in Hyderabad, then part of unified Andhra Pradesh, established a cooperative society to source chemical-free produce directly from farmers. Operating under the guidance of the Centre for Sustainable Agriculture (CSA), a Hyderabad-based research non-profit, the cooperative society over a period of time roped in a few farmers and began to sell the produce through a farmer-run retail store in Secunderabad and mobile retail vans that travelled to urban areas.

Hubballi, Bengaluru most-polluted cities during summer, says study

HUBBALLI: Bengaluru and Hubballi were the two most-polluted cities in south India the previous summer. Vijayapura is the least-polluted city, while Mangaluru has registered a declining trend in both summer average and peak compared to the previous summer. A study conducted by the Delhi-based Centre for Science and Environment (CSE) has revealed that smaller cities are becoming pollution hotspots than mega cities. CSE has said that the data was collected from Central Pollution Control Board's (CPCB) official portal, and Central Control Room for Air Quality Management. "The data has been captured from 356 official stations under the Continuous Ambient Air Quality Monitoring System (CAAQMS) spread across 174 cities in 26 states and Union Territories," it added. As Karnataka has 23 real-time stations, city-wide average is used for analysis, and 39 cities of south India were chosen for the study. Most polluted city in the region was Hyderabad with summer average of 47 g/m³ followed by Bengaluru and Hubballi with 40 g/m³. Hubballi has registered peak with 76 g/m³ while Bengaluru's peak summer pollution is 63 g/m³. Along with Gummidipoondi in Tamil Nadu, Karnataka's Vijayapura has recorded the lowest summer average in the south India. Madikeri, Bengaluru and Chikkaballapura have been identified among eight cities in the region that have shown increasing trend - that is, both summer average and peak have increased compared to their previous summer. Hubballi and Yadgir have been identified among six cities in the region that show mixed trend in their summer average and peak pollution level compared to the previous summer. Mangaluru is one among five cities in the region that has shown declining trend in both summer average and peak decreased compared to its previous summer. It has shown the most divergent trend with a decline in peak average by 73%, and summer average decline by 31%. Vaman Acharya, former chairman of Karnataka State Pollution Control Board, said there are mainly three reasons fort the summer pollution to increase in smaller cities. "Though they are not industrialised in a big way, construction works like road doubling are causing dust. The number of trees is decreasing compared to tier-1 cities. Construction waste from old buildings' demolition is not being disposed properly. So there is a need to tackle the issue on a priority."

Kolkata focus now on car-centric transit: Experts

KOLKATA: While private buses have steadily gone off roads, the city has witnessed a steeper rise in personal vehicles compared to pre-Covid years. This year, over 9,000 cars have been registered with the PVD Kolkata till July 31. By contrast, the entire pre-Covid year of 2019 saw 11,633 car registrations. In the two-wheeler category, too, this year's registration figures look set to beat pre-pandemic numbers. Till July 31, 11,712 two-wheelers have been registered in the city, while the figure in all of 2019 was 19,391. "These are signs of a weakening of the public transport system, which received a blow during the pandemic," said transport expert Anumita Roychowdhury, executive director, Centre for Science and Environment. Traffic and transport planning experts feel the city's focus has shifted from mass transit to a car-centric transit policy. "We have built elevated corridors, which eat into the carriageway. They mainly serve the car population. Thus, we are actually encouraging cars and discouraging the bus system, which has been the backbone of the city's transport," said Ajay Das, former chief of traffic and transportation planning directorate. Sharif Qamar, convener, Centre for Sustainable Mobility, TERI, said, "In an over-populated city like Kolkata, we need more mass transit systems which facilitate dispersal of a large volume of commuters in one go. More cars mean more congestion and pollution."

Noida Supertech towers' debris a risk to nearby buildings, may cause pollution, say experts

Experts say waste left behind in the basement will pose a serious threat to the environment and nearby residents and should be immediately transported to recycling plants or sent to construction sites for reuse The Supertech twin towers took nine seconds to vanish from the Noida skyline, but the mountain of rubble they left behind would take months to clear and is likely to pose a hazard to building structures nearby and add to air pollution. The Apex and Ceyane towers in Emerald Court in Noida’s Sector 93A on August 28 became the highest buildings to be demolished in India, a little over a year after the Supreme Court ordered them razed for illegal construction. Approximately 35,000 cubic metres of rubble would be left behind after the demolition, according to calculations made by project officials. As per the plan, the basements of the towers would house a big chunk of the debris, while the remainder would be transported to a remote area of Noida and processed scientifically. Experts, however, have flagged concerns over construction and demolition (C&D) waste created by the demolition. The Noida planning authority states that 21,000 cubic metres of debris will be transported to and dumped in a remote area within the city's Work Circle 7 boundaries. According to reports, the identified area is six hectares in size. The remaining waste will be buried/stored in a pit dug at the twin tower site. This implies that approximately 1,200 to 1,300 "truckloads" of debris would be removed from the site. Also read: Noida Supertech buildings razed. What happens to the homebuyers now? Experts raise concerns Rajesh K, a C&D waste demolisher in Bengaluru said, "The plans for C&D waste in Supertech demolition seem ambiguous and vague. The recycling plant in Noida has a capacity of 300 tonne per day and it will take almost three months to recycle the waste carried to the plant." Twin towers graphic According to a 2016 notification by the Central Pollution Control Board (CPCB), every state to set up C&D waste recycling plants in all cities with a population of more than 10 lakh. Rajesh said the waste left behind in the basement will pose serious threats to the environment and nearby residents. "When we leave the waste in the basement, there are chances of water seeping into the holes created by the explosion leading to water accumulation. This may affect the stability in the soil around the site, weakening the building structures nearby," he added. Experts also said that the rubble from the demolition is in large chunks and needs to be cut into smaller pieces for transportation to recycling plants. "This will happen over the next three months, and may add to the air pollution as we will be adding fine particulate matter into the air," Rajesh said. "At this moment, some parts will be taken to the recycling plant. Now, we have to ensure what has been taken to the recycling site should be quickly turned back into recycled materials to minimise the impact on carbon footprint," Anumita Roychowdhury, Executive Director, Centre for Science and Environment said. The waterlogging at the cavity area may have several impacts including pollution of groundwater, she said. "The debris will contain several toxic chemicals due to the explosives, and when water percolates into the water table below, it may carry chemicals with it," she added. "We need to understand if the builder has a clear plan to take the debris away from the site. As of now, their strategies are unclear, she said. Also read: Noida twin towers demolition: Timeline of key events Debris clearance Experts said while there are rules about recycling building waste, most of the time it is dumped in landfills or on city outskirts. "This problem is prevalent across the country," Akash Vashisht, an environmental lawyer, said, adding the damage it does to the environment is equivalent to that wrought by plastic or other forms of waste. "After the demolition, we have to segregate the waste into different components like steel, soil, etc and transport them for recycling. It is an opportunity for local authorities to show the best practices of implementing C&D waste management rules," he said. Also read: Twin tower demolition 'largely successful'; residents can return after 6.30 pm: Noida CEO Past demolitions Rajesh said Edifice Engineering, the Mumbai-based firm that carried out the Supertech demolitions, has done two major demolitions in the past, one in Kochi and another in Bengaluru two months back. "In the case of apartments in Maradu, Kochi, Edifice has removed the steel and left behind the debris for months that led to several National Green Tribunal cases," he said. Also read: Twin towers demolition: Supertech says it lost Rs 500 crore In 2021, the Kerala State Pollution Control Board said, the Maradu municipality has not yet provided facilities following the requirements of the Solid Waste Management and Construction and Demolition Waste Management Rules, 2016. "In the case of Bengaluru, the recent demolition of floors at Raheja building in Koramangala, we did not get a single truckload of construction waste," he added. Other environmental experts in Bengaluru add nobody knows where the construction debris was sent.

Catalyzing action in states to combat antimicrobial resistance

Recognizing antimicrobial resistance (AMR) as a key threat to global health, food security, and development, the WHO Country Office for India and Centre for Science and Environment (CSE) organized a workshop to trigger action on developing and implementing state action plans for the containment of AMR (SAPCAR) from 8–10 August 2022 at Neemli in the state of Rajasthan. Speaking at the event, WHO Representative to India Dr Roderico Ofrin called attention to the need for bridging silos between sectors through sharing information, best practices and collaborating on sector-specific activities. Effective strategies to combat AMR necessitates adoption of “one health” – a collaborative, multisectoral and transdisciplinary approach – which recognizes the interlinkages between humans, animals, plants and the environment as well as the need to work cohesively at the local, regional, national and global levels. About 77 participants from 19 states and union territories including experts from environment, livestock, fisheries, crops, and food sectors attended the event to discuss way forward. India’s National Action Plan on Antimicrobial Resistance (NAP-AMR) and the Delhi Declaration on AMR launched by Union Ministers for Health and Family Welfare, Environment, and Food, underscore the political commitment to tackle AMR. The NAP-AMR envisages the development of SAPCAR since human health, animal health, agriculture, fisheries, water, and sanitation are all state subjects under the Indian constitution. In addition to death, disability, AMR results in longer hospital stays and financial hardship for those impacted. The cost to the economy too is quite significant. In 2019, bacterial AMR infections caused nearly 1.3 million deaths globally and played a role in 5 million deaths. By 2050, India is expected to have two million deaths every year due to AMR. An intersectoral collaboration and action at the state level will be critical for AMR containment. Currently, only three states have formally launched their SAPCAR – Kerala, Madhya Pradesh and Delhi. The workshop will serve in expediting the roll-out of state action plans on AMR and addressing challenges that need to be understood and addressed for effective implementation at the sub-national levels.

नोएडा ट्विन टावर के गिरने से सता रही प्रदूषण की चिंता, CSE एक्सपर्ट बोले- दिल्ली-NCR में लंबे समय तक रहेगा असर

नोएडा स्थित सुपरटेक ट्विन टावरों को 28 अगस्त को गिरा दिया जाएगा। इन टावरों को विस्फोटक की मदद से ध्वस्त किया जाएगा। इन दोनों टावरों को गिराने से होने वाले कंपन और प्रदूषण को लेकर लोगों के बीच चिंता बढ़ गई है। एक तरफ जहां इस टावर के पड़ोस में रहने वाले लोगों को अपने घर को नुकसान पहुंचने का खतरा मंडरा रहा है तो दूसरी तरफ प्रदूषण का खतरा भी सता रहा है। टावर को गिराए जाने से भारी मात्रा में धूल और मिट्टी प्रदूषण फैलाएगी। लिहाजा आस-पास रहने वाले लोगों को काफी मुश्किल का सामना करना पड़ सकता है। वहीं पर्यावरण के एक्सपर्ट का मानना है कि यह धूल-मिट्टी एक दिन के लिए नहीं रहेगी बल्कि इससे वायु में पैदा हुआ वायु प्रदूषण कई दिनों तक लोगों को परेशान करेगा। लोगों को कई तरह की मुश्किलें हो सकती हैं। इसका असर पूरे दिल्ली और एनसीआर में देखने को मिलेगा और प्रदूषण का स्तर बढ़ सकता है। 4 सितंबर तक का समय बता दें कि इन टावरों को ध्वस्त किए जाने को कई बार चुनौती दी गई। लेकिन 12 अगस्त को सुप्रीम कोर्ट ने टावर को ध्वस्त करने की इजाजत दे दी। कोर्ट के आदेश के बाद 28 अगस्त को दोपहर 2.30 बजे इन टावरों को गिरा दिया जाएगा। अगर किसी भी तरह की तकनीकी दिक्कत आती है या फिर मौसम सही नहीं रहता है तो सुप्रीम कोर्ट ने इसके लिए 4 सितंबर तक का समय दिया है। देश की सबसे ऊंची इमारत हो रही ध्वस्त बिल्डिंग को ध्वस्त किए जाने की प्रक्रिया नियंत्रिण परिस्थितियों में की जाएगी। लेकिन बावजूद इसके पर्यावरण को लेकर चिंता बनी हुई है। सबसे बड़ी चिंता यूपी प्रदूषण नियंत्रमण बोर्ड ने जाहिर की है। बिल्डिंग में ब्लास्ट के बाद इसके गिरने से आसमान में उठने वाला धुंआ हवा की गुणवत्ता को खराब कर सकता है। माना जा रहा है कि इसकी वजह से पीएम10 कई दिनों तक बढ़ा रहेगा। पीएम 2-5 भी प्रभावित होगा। बता दें कि ट्विन टॉवर कुतुब मीनार से भी ऊंचे हैं और भारत की सबसे ऊंची इमारत है जिसे ध्वस्त किया जाएगा। आस-पास के लोगों को होगी दिक्कत Ads by एक्सपर्ट ने धूल, धुंआ और वायु प्रदूषण को लेकर सबसे अधिक चिंता जाहिर की है। इसकी वजह से आस-पास रहने वाले लोगों के स्वास्थ्य पर असर पड़ सकता है। लोगों की आंख में खुजली हो सकती है, नाक में भी खुजली हो सकती है। अस्थमा से पीड़ित लोगों को ज्यादा दिक्कत होगी। आईआईटी कानपुर के सिविल इंजीनियरिंग के वरिष्ठ प्रोफेसर डॉक्टर सच्चिदानंद ने कहा कि यह बड़े स्तर का ध्वस्तिकरण है, लेकिन मुझे नहीं लगता है कि इसके लंबे प्रभाव होंगे। मुझे संदेह है कि यह हफ्ते से ज्यादा नहीं रहेगा।

North India Pollution Alert: Along with Delhi, many cities of Haryana and UP also became hot spots of air pollution

This year, in the months of March, April and May, not only did the heat break the record, but the air pollution also remained at high level. PM 2.5 levels remained high across North India. This year, in the months of March, April and May, not only did the heat break the record, but the air pollution also remained at high level. PM 2.5 levels remained high across North India. Bhiwadi, Manesar, Ghaziabad, Delhi and Noida hot spots are being built in NCR. This finding has come out in an analysis by the Center for Science and Environment (CSE). This analysis was done over the time period from March 1 to May 31. For this, data was collected from 356 stations under Continuous Ambient Air Quality Monitoring System in 174 cities of 26 states and union territories through the online portal of Central Pollution Control Board (CPCB). North India is the most polluted, Delhi-NCR is the hotspot of pollution in summer. The summer average level of PM 2.5 in northern India is 71 micrograms per square metre, the highest among all regions. East India was the second worst-hit region with a summer average of 69 micrograms per square metre. West India (54 micrograms per cubic metre) and central India (46 micrograms per cubic metre) also recorded higher than normal summer levels of 40 micrograms per square metre. Northeast and South India remained clean as compared to other regions, where PM 2.5 levels were recorded at 35 and 31 micrograms per square metre, respectively. Delhi NCR was found to be the most polluted sub-region in North India. The summer average of PM 2.5 was very high in Delhi-NCR cities, with Bhiwadi recording the highest at 134 micrograms per square metre. Manesar (119 micrograms per cubic metre), Ghaziabad (101 micrograms per cubic metre), Delhi (97 micrograms per cubic metre), Gurugram (94 micrograms per cubic metre) and Noida (80 micrograms per cubic metre) were no less polluted. The average level of PM 2.5 in the NCR region is almost three times the average of cities in southern India. North India has registered a 23 per cent increase in the seasonal PM 2.5 level as compared to the previous summer. NCR was the worst-performing sub-region in northern India with a 25.8 per cent increase in seasonal PM 2.5 levels. 12 cities of Delhi-NCR are among the top 20 cities with highest pollution levels this summer. 19 cities in the region show an increasing trend, i.e. both summer average and peak increase compared to their previous summer. Hapur in Uttar Pradesh saw an astonishing 210 percent increase in the summer average and an average increase of 265 percent. In Haryana, Kaithal recorded an increase of 123 percent in the summer average and 96 percent in the peak.

Pollution: लोगों का दम घोंट रहा प्रदूषण, हवाओं में जहर घुलने से छोटे शहर बने नए हॉटस्पॉट, गर्मियों में हालत और गंभीर

Pollution Causes: प्रदूषण एक ऐसी समस्या है, जिससे होने वाली मौतों और इससे होने वाले नुकसान का पता लगाने का कोई वैज्ञानिक आधार फिलहाल मौजूद नहीं है. लेकिन ये एक ऐसी बीमारी बन चुकी है जो 24 घंटे हमें नुकसान पहुंचा रही है. CSE यानी Centre for Science and Environment ने गर्मियों में वायु प्रदूषण के स्तर का डाटा जारी किया है. इस डाटा के मुताबिक केवल दिल्ली जैसे बडे शहर ही नहीं, अब छोटे शहरों में भी प्रदूषण नए रिकॉर्ड बना रहा है. हालांकि दिल्ली-NCR रीजन अब भी प्रदूषण के मामले में टॉप पर है. दक्षिणी राज्यों के मुकाबले दिल्ली एनसीआर में प्रदूषण का स्तर तीन गुना ज्यादा है. इस वर्ष पिछली गर्मी के मुकाबले प्रदूषण ज्यादा रहा है. भारत के सबसे प्रदूषित शहर इस रिपोर्ट के लिहाज से देखें तो अब भारत का सबसे प्रदूषित शहर राजस्थान का भिवाड़ी है, जहां गर्मियों के दौरान प्रदूषण का औसत 134 रहा. इसके बाद हरियाणा के मानेसर की बारी आती है जो भारत का दूसरा सबसे प्रदूषित शहर है. यहां गर्मियों के प्रदूषण का औसत 119 रहा. तीसरे नंबर पर मध्य प्रदेश का सिंगरौली जिला का है, जहां प्रदूषण का स्तर 110 रहा. इसके बाद हरियाणा के रोहतक और उत्तर प्रदेश के मुजफ्फरनगर का नंबर है. भारत के 20 सबसे प्रदूषित शहरों में 12 शहर दिल्ली एनसीआर के हैं. गर्मियों में भारत के सबसे कम प्रदूषित शहरों की बात की जाए तो मिजोरम का एजवाल और तमिलनाडु का गुम्मीडिपुंडी सबसे कम प्रदूषित है.

2022 की गर्मी: दिल्ली-एनसीआर उत्तर भारत में सबसे अधिक प्रदूषित

सेंटर फॉर साइंस एंड एनवायरनमेंट (सीएसई) के एक नए विश्लेषण के अनुसार, 2022 की गर्मी न केवल असामान्य रूप से गर्म थी, बल्कि हवा में विशेष रूप से उत्तर भारत में कण प्रदूषण की एक अस्वाभाविक रूप से उच्च उपस्थिति थी। दिल्ली-एनसीआर उत्तर भारत में सबसे प्रदूषित उप-क्षेत्र पाया गया, गर्मियों में औसत पीएम2.5 71 माइक्रोग्राम प्रति वर्ग मीटर के साथ। भिवाड़ी का ग्रीष्मकालीन औसत 134 माइक्रोग्राम प्रति घन मीटर पर सबसे अधिक था, इसके बाद मानेसर (119 माइक्रोग्राम / एम³), गाजियाबाद (101 माइक्रोग्राम / एम³), दिल्ली (97 माइक्रोग्राम / एम³), गुरुग्राम (94 माइक्रोग्राम / एम³) और नोएडा (80) थे। माइक्रोग्राम / एम³)। दिल्ली-एनसीआर का औसत पीएम2.5 दक्षिण भारत के शहरों की तुलना में लगभग तीन गुना था। बुधवार को जारी की गई रिपोर्ट केंद्रीय प्रदूषण नियंत्रण बोर्ड के 1 मार्च से 31 मई, 2022 के बीच की वायु गुणवत्ता के वास्तविक आंकड़ों पर आधारित है। कुल मिलाकर दिल्ली को देश में आठवां स्थान मिला है। दिल्ली-एनसीआर के बारह शहर भारत के 20 सबसे प्रदूषित शहरों में शामिल हैं, जबकि हरियाणा के पांच शहर सबसे खराब 10 शहरों में शामिल हैं। इस गर्मी में मिजोरम में ऐवज़ल और तमिलनाडु में गुम्मीदीपोंडी देश के सबसे कम प्रदूषित शहर थे। अपने शहर में प्रदूषण के स्तर को ट्रैक करें सीएसई की कार्यकारी निदेशक (अनुसंधान और वकालत) अनुमिता रॉयचौधरी कहती हैं, “शुष्क परिस्थितियों, उच्च गर्मी की गर्मी और तापमान, और लंबी दूरी की यात्रा करने वाले अधिक वायुजनित धूल कणों के कारण गर्मी के कण प्रदूषण स्पाइक्स, स्थानीय स्रोतों से समस्या को बढ़ाते हैं।” विश्लेषण के अनुसार, उत्तर भारत ने पिछली गर्मियों की तुलना में मौसमी PM2.5 स्तर में 23% की वृद्धि दर्ज की, जो उन शहरों के औसत पर आधारित है, जिनमें दोनों गर्मियों (1 मार्च से 31 मई) के दैनिक PM2.5 एकाग्रता डेटा हैं। . मौसमी PM2.5 के स्तर में 25.8% की वृद्धि के साथ एनसीआर का प्रदर्शन सबसे खराब रहा। अर्बन लैब के सीनियर प्रोग्राम मैनेजर अविकल सोमवंशी ने कहा, “कई क्षेत्रों में उच्च कण प्रदूषण का अनुभव हुआ, जब हीट-वेव की स्थिति भी व्यापक और तीव्र थी।”

गर्मियों के दौरान उत्तर भारत में सबसे ज्यादा जहरीली थी हवा, दिल्ली-NCR रहा हॉटस्पॉट : सीएसई

नयी दिल्ली : इस साल गर्मियों न केवल असामान्य रूप से गर्म थी, बल्कि साथ ही देश के कई शहरों में प्रदूषण का स्तर भी बहुत ज्यादा था। सेंटर फॉर साइंस एंड एनवायरनमेंट (सीएसई) द्वारा जारी नए विश्लेषण से पता चला है कि गर्मियों के दौरान देश में उत्तर भारत की हवा सबसे ज्यादा जहरीली थी। जहां पीएम2.5 का औसत स्तर 71 माइक्रोग्राम प्रति घन मीटर दर्ज किया गया, जोकि विश्व स्वास्थ्य संगठन द्वारा तय मानक 5 माइक्रोग्राम प्रति घन मीटर से 14 गुना ज्यादा था। विश्लेषण से पता चला है कि पीएम2.5 का बढ़ता स्तर न केवल कुछ बड़े और खास शहरों तक ही सीमित है बल्कि अब वो एक राष्ट्रव्यापी समस्या बन चुका है। जानकारी मिली है कि दिल्ली-एनसीआर क्षेत्र गर्मियों में प्रदूषण का सबसे बड़ा हॉटस्पॉट था। मार्च 01 से 31 मई के बीच जहां भिवाड़ी में पीएम2.5 का स्तर सबसे ज्यादा बदतर था जो 134 माइक्रोग्राम प्रति वर्ग मीटर दर्ज किया गया था। वहीं प्रदूषण का यह स्तर मानेसर में 119, गाजियाबाद 101, दिल्ली में 97, गुरुग्राम में 94 और नोएडा में 80 माइक्रोग्राम प्रति घन मीटर तक पहुंच गया था। देखा जाए तो दिल्ली-एनसीआर क्षेत्र में पीएम2.5 का यह स्तर दक्षिण भारतीय शहरों के औसत पीएम2.5 के स्तर का करीब तीन गुना था। देखा जाए तो इस दौरान देश के 20 सबसे ज्यादा प्रदूषित शहरों में से 10 हरियाणा के थे। विश्लेषण के मुताबिक गर्मियों के दौरान पूर्वी भारत में पीएम2.5 का स्तर 69 माइक्रोग्राम प्रति घन मीटर था, जोकि उत्तर भारत के बाद देश में सबसे ज्यादा था। उसके बाद पश्चिम भारत में प्रदूषण का यह स्तर 54 माइक्रोग्राम प्रति घन मीटर, मध्य भारत में 46 माइक्रोग्राम प्रति घन मीटर दर्ज किया गया। वहीं इस दौरान पूर्वोत्तर भारत में प्रदूषण का यह स्तर 35 माइक्रोग्राम प्रति घन मीटर और दक्षिण भारत में 31 माइक्रोग्राम प्रति घन मीटर दर्ज किया गया। यदि प्रदूषण के दैनिक उच्चतम स्तर की बात की जाए तो वो पूर्वी भारत में दर्ज किया गया, जोकि 168 माइक्रोग्राम प्रति घन मीटर था। इसके बाद उत्तर भारत में 142, पश्चिम भारत में 106, मध्य भारत में 89, पूर्वोत्तर भारत में 81और दक्षिण भारत में 65 माइक्रोग्राम प्रति घन मीटर दर्ज किया गया। बड़े शहरों में ही नहीं छोटे शहरों में भी तेजी से बढ़ रही है प्रदूषण की समस्या वहीं यदि शहरों की बात करें तो बिहार शरीफ में पीएम2.5 का दैनिक औसत स्तर सबसे ज्यादा था जो 285 माइक्रोग्राम प्रति घन मीटर रहा। वहीं रोहतक में यह 258, कटिहार में 245 और पटना में 200 माइक्रोग्राम प्रति घन मीटर तक पहुंच गया था। कुल मिलकर देखा जाए तो इस बार गर्मियों में प्रदूषण का औसत स्तर पिछली गर्मियों की तुलना में कहीं ज्यादा रहा। वहीं उत्तर भारत ने पिछली गर्मियों की तुलना में पीएम2.5 के मौसमी स्तर में 23 फीसदी की वृद्धि दर्ज की गई है। प्रदूषण के यह आंकड़े एक बात तो स्पष्ट तौर पर दर्शाते हैं कि देश में प्रदूषण अब केवल बड़े शहरों तक ही सीमित नहीं रह गया है छोटे शहर भी इसके हॉटस्पॉट बन रहे हैं। यह बात 2022 में गर्मियों के दौरान देश के सबसे प्रदूषित शहरों की लिस्ट में भी साफ-तौर पर नजर आती है, जिसमें राजस्थान का भिवाड़ी शहर सबसे प्रदूषित शहरों में सबसे ऊपर था। सीएसई के अनुसार गर्मियों में प्रदूषण के इस ऊंचे स्तर के लिए न केवल वाहनों से निकला धुआं बल्कि उद्योग, बिजली संयंत्रों और अपशिष्ट पदार्थों को जलाने से पैदा हो रहा प्रदूषण भी इसके लिए जिम्मेवार था। इनके अलावा हवा में उड़ती धूल जो गर्म और शुष्क परिस्थितियों के चलते काफी बढ़ गई थी वो भी कहीं न कहीं इस बढ़ते प्रदूषण के लिए जिम्मेवार थी। क्या है समाधान? इस बारे में सेंटर फॉर साइंस एंड एनवायरनमेंट की कार्यकारी निदेशक अनुमिता रॉयचौधरी का कहना है कि, “यह विश्लेषण सभी क्षेत्रों में प्रदूषण के अनूठे पैटर्न पर प्रकाश डालता है। यह बड़ी संख्या में ऐसे कस्बों और शहरों की पहचान करता है जिन पर प्रदूषण के मामले में नीतिगत रूप से ध्यान नहीं दिया जा रहा है।” उनका कहना है कि गर्मियों में प्रदूषण के बढ़ने के पीछे शुष्क परिस्थितियां के साथ भीषण गर्मी और तापमान भी वजह थे, जिनकी वजह से कहीं ज्यादा धूलकण लंबी दूरी तक यात्रा करते हैं। ऐसे में सीएसई का कहना है कि इस बढ़ते प्रदूषण के जहर से बचने के लिए देश में सभी स्रोतों से होते उत्सर्जन में कटौती करने की जरुरत है, जिसके लिए कड़े कदम उठाने होंगें। इसके साथ ही मरुस्थलीकरण से निपटने, मिट्टी में स्थिरता लाने और वनावरण को भी बढ़ाने की जरुरत है। साथ ही शहरों में बढ़ती गर्मी के कहर से निपटने के साथ ही जंगल और फसलों में लगने वाली आग को रोकने के लिए भी बड़े पैमाने पर प्रयास करने की आवश्यकता है।

North India most-polluted region in 2022 summers: CSE

North India emerged as the most-polluted region in the country in summers this year with Delhi-NCR being the hotspot, according to a new analysis by the Centre for Science and Environment (CSE). The green think-tank said the average PM2.5 concentration in north India in summers stood at 71 microgram per cubic metre.

Summer 2022 battered by heat waves, high particulate pollution, CSE assessment

The summer of 2022 was not only unusually hot but also uncharacteristically high in particulate pollution, especially in north India. High PM 2.5 levels were observed across multiple cities and regions as the pollution has not been confined to a few megacities or a specific region — it has turned into a widespread national problem. This has emerged from the analysis of summer air quality undertaken as part of the air quality tracker initiative of the urban lab at the Centre for Science and Environment (CSE). Summer days from March 1 to May 31 have been considered for the analysis, as rains had set in during June in several regions. As the availability of real-time air quality data has improved in several regions with the expansion of the air quality monitoring systems, it has become possible to assess the regional differences and understand the unique regional trends. “This analysis identifies the unique patterns of pollution across all regions and puts a spotlight on a large number of towns and cities that do not get policy attention. Summer particulate pollution spikes due to arid conditions, high summer heat and temperature, and more airborne dust particles that travel long distances compounding the problem from local sources,” says Anumita Roychowdhury, executive director, research and advocacy, CSE. “This air quality tracker initiative has helped to benchmark the summer air quality for peer-to-peer comparison within each region and understand the inter-regional differences that need to inform policy action. Several regions experienced high particulate pollution when heat wave conditions were also widespread and intense,” says Avikal Somvanshi, senior programme manager at the Urban Lab. This data analysis is based on publicly available granular real-time data (15-minute averages) from the Central Pollution Control Board’s (CPCB) official online portal, Central Control Room for Air Quality Management. The data is captured from 356 official stations under the Continuous Ambient Air Quality Monitoring System (CAAQMS) spread across 174 cities in 26 states and Union territories. As per findings, North India is the most polluted, with Delhi-NCR being the summer pollution hotspot. Summer average PM2.5 for North India stood at 71 µg/m³, the highest among all the regions. East India with 69 µg/m³ summer average was the second worst. West India (54 µg/m³) and Central India (46 µg/m³) also recorded summer level access of 40 µg/m³. Northeast India (35 µg/m³) and South India (31 µg/m³) were the cleaners compared to other regions. Daily peak pollution was highest in east India, with cities of Bihar recording the highest levels. It was found that the average pollution this summer was higher than the previous summer. North India has recorded a staggering 23 per cent increase in seasonal PM2.5 level compared to the previous summer based on an average of cities that have valid daily PM2.5 concentration data of both summers. Smaller cities and towns dominate the most polluted list for this summer. The way forward: Says Roychowdhury: “Overall, seasonal pollution is expected to be highly variable due to the impact of local and regional pollution, and meteorological and climatic impacts that need to inform policy making. Due to arid and heat conditions and growing desertification, summer months usually witness high dust impacts. But the dust is also a carrier of toxic substances from combustion sources including vehicles, industry, power plants, and the burning of waste. While the local nature of this problem needs to be investigated in all regions, this requires significant tightening of action to control emissions from each pollution source as well as massive efforts to combat desertification, improve soil stabilisation, and green-walling through afforestation, and reduce the heat island effect in cities.”

Delhi-NCR emerges as essentially the most polluted metropolis in north India; North India essentially the most polluted area within the nation

North India emerged because the most-polluted area within the nation in summers this 12 months with Delhi-NCR being the hotspot, in accordance with a brand new evaluation by the Centre for Science and Atmosphere (CSE). The inexperienced think-tank mentioned the common PM2.5 focus in north India in summers stood at 71 microgram per cubic metre. It was 69 microgram per cubic metre in east India, 54 microgram per cubic metre in west India, and 46 microgram per cubic metre in central India, it mentioned. Northeast India (35 microgram per cubic metre) and South India (31 microgram per cubic metre) have been cleaner in comparison with different areas, it mentioned. In north India, Delhi-NCR was discovered to be the most-polluted sub-region, with Bhiwadi reporting the best common PM2.5 focus of 134 microgram per cubic metre. Associated Information Kolkatas air quality second worst among 103 most populated global cities Kolkata’s air high quality second worst amongst 103 most populated world cities Drones grounded for twin towers demolition in Noida no fly zone announced for August 28 Drones grounded for twin towers’ demolition in Noida, ‘no fly zone’ introduced for August 28 Manesar reported a mean PM2.5 focus of 119 microgram per cubic metre, Ghaziabad (101 microgram per cubic metre), Delhi (97 microgram per cubic metre), Gurugram (94 microgram per cubic metre) and Noida (80 microgram per cubic metre), it mentioned. PM2.5 summer time common of Delhi-NCR area is nearly 3 times the common of the cities in southern India. The CSE used granular real-time knowledge from the Central Air pollution Management Board’s portal — Central Management Room for Air High quality Administration for the evaluation.

Summer season of 2022: Delhi-NCR most polluted in north India | Delhi Information – Instances of India

The summer season of 2022 was not solely unusually sizzling, but additionally had an uncharacteristically excessive presence of particulate air pollution within the air, particularly in north India, in response to a brand new evaluation by Centre for Science and Surroundings (CSE). Delhi-NCR was discovered to be essentially the most polluted sub-region in north India, with summer season common PM2.5 at 71 µg/m³. Bhiwadi’s summer season common was the best at 134 micrograms per cubic metre, adopted by Manesar (119 µg/m³), Ghaziabad (101 µg/m³), Delhi (97 µg/m³), Gurugram (94 µg/m³) and Noida (80 µg/m³). Delhi-NCR’s common PM2.5 was nearly thrice as that of cities in south India. va The report, which was launched on Wednesday, relies on Central Air pollution Management Board’s real-time air high quality information between March 1 and Might 31, 2022. General, Delhi has been ranked eighth within the nation. Twelve cities in Delhi-NCR featured among the many 20 most polluted in India whereas 5 from Haryana have been among the many worst 10. Aiwzal in Mizoram and Gummidipoondi in Tamil Nadu have been the least polluted cities within the nation this summer season. Monitor the air pollution stage in your metropolis “Summer season particulate air pollution spikes resulting from arid circumstances, excessive summer season warmth and temperature, and extra airborne mud particles that journey lengthy distances, compounding the issue from native sources,” says Anumita Roychowdhury, govt director, analysis and advocacy, CSE. In response to the evaluation, north India recorded a staggering 23% enhance in seasonal PM2.5 stage in contrast with the earlier summer season, based mostly on a mean of cities which have legitimate every day PM2.5 focus information of each summers (March 1 to Might 31). NCR fared the worst, with a 25.8% enhance in seasonal PM2.5 stage. “A number of areas skilled excessive particulate air pollution when heat-wave circumstances have been additionally widespread and intense,” stated Avikal Somvanshi, senior programme supervisor at City Lab.
