Is it the beginning or the end of the cycle? writes Anil Singh

Is the cycling culture that bloomed during the pandemic withering away with the resumption of normal traffic? Or does the buzz indicate that this is the beginning of a cycling revolution? Cycling and cyclists in Indian cities today are like the lover in Shakespeare’s lost poem, `Shall I die? Shall I fly?’ Indeed, like love, cycling in Mumbai is fraught with danger. Common sense says that it is back to being an adventure sport. One can get knocked down and killed like 12- year-old Aksha Malu last month. The boy and his father were returning home at 5 am on a Sunday with two other kids. They reckoned it was a safe time but no Indian road is ever safe for a cyclist; minutes away from their housing complex on Jogeshwari-Vikhroli Link Road, a cement mixer rammed Aksha’s bike. Experienced bikers too meet with fatal accidents. In November 2017, Ashok Khale (64), a champion cyclist and a mentor for many was killed on the Vashi bridge as he was pedalling from his residence in Dadar to Khopoli on a Sunday. Environmentalist Sunita Narain had a nasty collision while cycling in Delhi not so long ago. The NITI Aayog report on bicycles says that cyclists constituted 2.4 per cent of fatal road accidents in India during 2018. Even otherwise, danger lurks underfoot in potholes and drain grates which are poorly laid and sometimes open. But like love,Indians have taken to cycling despite all the dangers. Cycle sales which were stagnant before the pandemic grew by over two-fold, so much so that one has to wait four months for light-weight, geared cycles which cost up to Rs 3 lakhs. The adoption of cycling as a lifestyle is growing across age groups and is proof that the pandemic has changed mindsets. Entrepreneurs and politicians have been quick to cash in on this. Digital rental bike systems, which one sees in European countries, have cropped up in cities across India. Politicians are wooing GenX voters by setting up cycle tracks wherever possible and even organising cyclothons. On a national level, the India Cycles4Change Challenge launched in June 2020 prioritises the promotion of cycling through a collaborative method. Various state government initiatives such as Karnataka’s free bicycle distribution and West Bengal’s 25 lakh bicycle distribution further promote cycling. The Delhi government has decided to give a 25 per cent subsidy on the purchase of ebikes. Closer home in Mumbai, this Sunday, 13 stretches of road from Marine Drive to Band Stand will be reserved for cycling or any other activity that people happy. One can only hope that this pilot project succeeds like `Ciclovia’ in Bogota, Columbia, where 121 km is kept aside for cycling and fun activity from 7am to 2pm on Sundays, promoting tourism in a big way. Mumbai has built up a cycling culture in the last ten years. Cyclists hit the road early in the morning on weekends. There’s a cycling club in virtually every Mumbai suburb with membership running intohundreds; from schoolboys to senior citizens. They organise long rides during the weekends which cover forts to flowering trees flamingo sites and at times, heritage precincts. Then there are timed long-distance endurance events called brevets. However, the bulk of the riders are youngsters such as Nikhil George (27); a corporate executive whose weekday ride is from Worli to Nariman Point and back before the traffic starts. These young riders take precautions such as helmets, lights, bright uniforms, gloves, water bottles, riding in packs, and carrying their identity cards with them. Maharashtra’s Environment and Tourism minister Aaditya Thackeray has been pushing cycling although in his over-enthusiasm he tried to make a cycling track around Powai and Vihar lakes which are environmentally unsound. His dream project is a 39-km-long and 10-m wide track to be built on the space created by relocating 15,000 hutments along the Tansa pipeline— stretching from the eastern suburb of Mulund to Wadala in Mumbai city ---to seems to have run into trouble. However, phase 1 of the cycle track at BKC is complete. The 8.5km long promenades from Hali Ali to Worli to come up along with the Coastal road will also have a cycling track. Cycles will also prove useful in the last-mile connectivity from the metro stations which soon dot Mumbai. The place where cycling has taken off is Navi Mumbai where the Public Bicycle Sharing System(PBSS) or also known as Yulu Bikes introduced in 2018 has earned carbon credit worth Rs 38.61 cr from over 8.14 lakh rides. More than 2.5 lakhs citizens have already used the system. Now, the civic body has proposed to make a cycle track of around 7.5 km along the iconic Palm Beach Road. The Energy Research Institute (TERI) estimated in its 2018 report, ‘Benefits of Cycling in India: An Economic, Environmental, and Social Assessment, 2018’, that cycling for short distances can result in an annual benefit of Rs 1.8 trillion to the Indian economy, which is equivalent to 1.6% of India’s annual GDP. However, cycling enthusiasts bemoan the lack of advocacy and policy intervention. Bureaucrats themselves admit that there has been a lot of reluctance towards introducing cycles in Mumbai. Inaugurating the public cycle sharing system from Versova Metro station last year, the then MMRDA chief R A Rajeev had said, “There has been a reluctance to introduce bicycles in Mumbai by saying that the roads are congested. There are, however, two aspects to it. We have to introduce more of these facilities and people should also start cycling more. This will create a revolution and also decongest the roads.” He further said that when there are more cyclists on road, city planners will be forced to create space for them. “Create the demand and the city will give you space,” he said. The question however is: how many cyclists will have to die before that happens.

Human chain to save more than 2500 trees in Guwahati

Citizens of Guwahati plan to come out on the streets yet again to raise their voices against the merciless felling of more than 2500 trees to convert the 4-lane NH 27 (old NH 37) to a 6-lane road. The East Kamrup Forest Division recently revealed that 300 trees, approximately 70-80 years old, were cut during the two years in the COVID-19 pandemic for various infrastructural projects such as flyovers and roads. During the COVID-19 pandemic, while the citizens were stuck inside houses, many trees were chopped for infrastructural development, leaving no options for them to raise their voices. “Citizens have decided that they shall not be silent spectators anymore and shall hug the trees and form a human chain to express their dissatisfaction and create awareness on the importance of conserving age-old trees – following the suit of Sunderlal Bahugana and the women activists in the Chipko Movement, which inspires millions till today,” said a statement released by Fridays For Future, Guwahati. Karnika Goswami, a student of MA Linguistics at Delhi University, said: “Cutting down 2500 trees is a drastic step. We must protect these trees at any cost. This must feel personal to us – to try and save these trees. We must channelise our climate anxieties and come together for the sake of our city.” In the World Air Quality Report, 2021, prepared by a Swiss Organisation, IQAir, it was stated that based on air quality data collected from 6,475 cities in 117 countries, 63 out of 100 cities with the worst air quality were in India. In a study conducted by the Centre for Science and Environment (CSE), Guwahati turned out to be the most polluted city in the entire Northeast region with a winter average PM2.5 of 81 ug/m3. PM2.5 concentration of Guwahati’s air is currently 32.8 times above the WHO annual air quality standards and falls into the “very unhealthy” category. On the importance of trees inside the city, Aditya Das, biologist at Kamlang Tiger Reserve, said: “Trees contribute to the environment by sequestration of oxygen, improvisation of air quality and important ecosystem services like soil preservation, climate amelioration thereby supporting a large niche of wildlife. Urban trees play a huge role in reducing urban flooding by holding the water runoff and slowing down winds by reducing excessive heat loss from buildings. Most importantly, they are home to urban wildlife. Is cutting trees for infrastructural development, in this case, a 6-lane road, a solution to the problem of convenient mobility or a problem towards long term inconvenience?” The newly released 2nd part of the 6th assessment of the IPCC report alarms: “Globally, heat and humidity will create conditions beyond human tolerance if emissions are not rapidly eliminated. India is among the places to experience these intolerable conditions.” The Paris Agreement of 2015 seeks to keep the global rise in temperatures “well below” 2 degrees Celsius from pre-industrial times, a reference to the period between 1850 and 1900 while working towards restricting it to 1.5 degrees Celsius. Scientists have warned that until immediate actions are taken to rein in the rise in temperatures, even the 2-degree Celsius goal would become out of reach. “If our intention is to create more road space to accommodate more of our personal vehicles, we must also understand that it will only encourage more and more people to buy cars because the roads and the bridges have not reached full capacity yet. In the next 6 to 12 months, we will realise that the extra widened space which we created is again filled up by cars. So, to question our choice, which is called development, where are we really going with 1000s of trees being cut down for bridges after bridges and multiple lane roads?” asks Ashadeep Baruah, a social activist from Guwahati.

Darjeeling भारत का सबसे कम प्रदूषण वाला शहर है सिलीगुड़ी

पश्चिम बंगाल न्यूज़ डेस्क, पिछले सर्दियों के मौसम में देश के सभी क्षेत्रों में वायु प्रदूषक कणों का स्तर अलग-अलग तीव्रता के साथ बढ़ा है। हालांकि अधिकांश क्षेत्रों में पीएम2.5 का समग्र क्षेत्रीय औसत पिछली सर्दियों की तुलना में कम था, लेकिन कई क्षेत्रों में सर्दियों के कोहरे के चरण में तेज वृद्धि हुई थी। पड़ोसी राज्य बिहार में सिवन और मुंगेर देश के सबसे प्रदूषित शहर पाए गए हैं। दूसरी ओर, पूर्वोत्तर भारत का प्रवेश द्वार सिलीगुड़ी पूर्वी क्षेत्र का सबसे कम प्रदूषित शहर पाया गया है। पूर्वोत्तर भारत की राजधानी आइजोल, मिजोरम और मेघालय की राजधानी शिलांग देश के सबसे कम प्रदूषित शहर हैं। विज्ञान और पर्यावरण केंद्र ने 2021-22 (15 अक्टूबर 2021 से 28 फरवरी 2022) के ठंड के मौसम के दौरान देश भर में सर्दियों की हवा की गुणवत्ता का विश्लेषण किया है। यह विश्लेषण केंद्रीय प्रदूषण नियंत्रण बोर्ड (सीपीसीबी) के आधिकारिक ऑनलाइन पोर्टल वायु गुणवत्ता प्रबंधन के लिए केंद्रीय नियंत्रण कक्ष से उपलब्ध रीयल-टाइम डेटा (औसत 15 मिनट) पर आधारित है। 26 राज्यों और केंद्र शासित प्रदेशों के 161 शहरों में फैले कंटीन्यूअस एम्बिएंट एयर क्वालिटी मॉनिटरिंग सिस्टम (CAACMS) के तहत 326 आधिकारिक स्टेशनों से डेटा एकत्र किया गया था। अनुमिता राय चौधरी, कार्यकारी निदेशक, अनुसंधान और वकालत, सीएसई, और अविकल सोमवंशी, प्रबंधक, अर्बन डेटा एनालिटिक्स लैब, सिलीगुड़ी, पश्चिम बंगाल के अनुसार, पूर्वोत्तर में सबसे कम ठंड के मौसम का औसत है। दूसरी ओर, राज्य में कोलकाता, हावड़ा, आसनसोल, दुर्गापुर, हल्दिया और सिलीगुड़ी में औसतन 21 प्रतिशत की गिरावट और 27 प्रतिशत की चोटी दर्ज की गई।

हमारी जल सुरक्षा को गंभीर संकट में डाल सकता है बढ़ता तापमान

जलवायु परिवर्तन का युग है यह (This is the era of climate change) नई दिल्ली, 23 मार्च 2022. भारत के बड़े हिस्से में गर्मी की शुरूआत इतनी तेज गर्म लहर के साथ होने का क्या मतलब है? इस सवाल के जवाब पर सेंटर फॉर साइंस एंड एनवायरनमेंट (सीएसई) की महानिदेशक सुनीता नारायण ने कहा, “इसका मतलब है कि यह जलवायु परिवर्तन का युग है। साथ ही आने वाले दिनों में हम पानी के लिए क्या करेंगे, यह निर्धारित करेगा कि हम ऐसी जलवायु परिस्थितियों से बचे रहेंगे या नहीं।” जलवायु परिवर्तन के प्रभाव (effects of climate change) नारायण ने विस्तार से बताया, “मैं ऐसा इसलिए कह रही हूं क्योंकि हम सभी जानते हैं कि जलवायु परिवर्तन के प्रभाव गर्मी, चिलचिलाते तापमान और परिवर्तनशील और अत्यधिक बारिश के बारे में हैं। दोनों का जल चक्र के साथ सीधा संबंध है। इसलिए जलवायु परिवर्तन के बारे में पानी और उसका प्रबंधन होना चाहिए।” सीएसई, जलवायु परिवर्तन, उप कार्यक्रम प्रबंधक, अवंतिका गोस्वामी ने कहा, भारत में 2021 की स्थिति दोहराई जा रही है, जब देश के कुछ हिस्सों में फरवरी की शुरूआत में तापमान 40 डिग्री सेल्सियस को छू गया था, और यह तब हुआ जब 2021 ला नीना का साल था, जिसमें प्रशांत जल धाराएं विश्व स्तर पर ठंडा तापमान लाने के लिए जानी जाती हैं। भारतीय मौसम वैज्ञानिकों ने सूचित किया है कि ग्लोबल वार्मिग ला नीना के इस प्रभाव की भरपाई करेगी। Rising heat has serious impact on water security सीएसई के शोधकर्ता के अनुसार, बढ़ती गर्मी का जल सुरक्षा पर गंभीर प्रभाव पड़ता है। सबसे पहले इसका मतलब जल निकायों से ज्यादा वाष्पीकरण होना है। नारायण ने आगे कहा कि “इसका मतलब है कि हमें न केवल लाखों संरचनाओं में पानी के भंडारण पर काम करने की जरूरत है, बल्कि वाष्पीकरण के कारण होने वाले नुकसान को कम करने की भी योजना बनानी है। ऐसा नहीं है कि वाष्पीकरण नुकसान पहले में नहीं हुआ हैं, लेकिन वाष्पीकरण की दर में अब बढ़ते तापमान के साथ वृद्धि होगी।” सीएसई के शोधकर्ताओं के अनुसार, एक विकल्प भूमिगत जल भंडारण या कुओं पर काम करना है। भारत के सिंचाई योजनाकार और नौकरशाही काफी हद तक नहरों और अन्य सतही जल प्रणालियों पर निर्भर हैं, उन्हें भूजल प्रणालियों के प्रबंधन में छूट नहीं देनी चाहिए। गर्मी बढ़ने से मिट्टी की नमी सूख सकती है। यह जमीन पर और ज्यादा धूल कर देगा और इससे सिंचाई की महत्ता बढ़ेगी। भारत जैसे देश में जहां अभी भी अधिकांश अनाज वर्षा आधारित क्षेत्रों में उगाया जाता है। बारिश से सिंचित यह भूमि क्षरण को और तेज करेगा। इसका मतलब है कि जल प्रबंधन को वनस्पति योजना के साथ हाथ से जाना चाहिए ताकि मिट्टी की पानी धारण करने की क्षमता में सुधार हो सके, यहां तक कि तीव्र और लंबी गर्मी के समय में भी ऐसा होना चाहिए। Water demand will increase with climate change तीसरा और स्पष्ट रूप से गर्मी पानी के उपयोग को बढ़ाएगी, जिसमें पीने और सिंचाई से लेकर जंगलों या इमारतों में आग से लड़ना शामिल हैं। हम पहले ही दुनिया के कई हिस्सों में और भारत के जंगलों में विनाशकारी जंगल की आग को देख चुके हैं। तापमान बढ़ने के साथ ही यह और बढ़ेगा। जलवायु परिवर्तन के साथ पानी की मांग बढ़ेगी, जिससे यह और भी जरूरी हो जाएगा कि हम पानी या अपशिष्ट जल को बर्बाद न करें। इतना ही नहीं, तथ्य यह है कि अत्यधिक बारिश की घटनाओं की बढ़ती संख्या के संदर्भ में जलवायु परिवर्तन पहले से ही दिखाई दे रहा है। इसका मतलब है कि हम बारिश को बाढ़ के रूप में आने की उम्मीद कर सकते हैं, जिससे बाढ़ के बाद सूखे का चक्र और भी तीव्र हो जाएगा। भारत में पहले से ही एक वर्ष में कम बरसात के दिन होते हैं। ऐसा कहा जाता है कि एक वर्ष में औसतन केवल 100 घंटे बारिश होती है। अब बारिश के दिनों की संख्या और कम हो जाएगी, लेकिन अत्यधिक बारिश के दिनों में वृद्धि होगी। इसका जल प्रबंधन की हमारी योजनाओं पर व्यापक प्रभाव पड़ा है। इसका मतलब है कि हमें बाढ़ प्रबंधन के बारे में और अधिक सोचने की जरूरत है न केवल नदियों के तटबंध के लिए बल्कि बाढ़ के पानी को अनुकूलित करने के लिए ताकि हम उन्हें भूमिगत और भूमिगत जलभृतों, कुओं और तालाबों में संग्रहीत कर सकें। इसका मतलब यह भी है कि हमें बारिश के पानी को बचाने के लिए अलग तरह से योजना बनाने की जरूरत है। उदाहरण के लिए वर्तमान में, महात्मा गांधी राष्ट्रीय ग्रामीण रोजगार गारंटी अधिनियम के तहत बनाए जा रहे लाखों जल ढांचे, सामान्य वर्षा के लिए डिजाइन किए गए हैं। लेकिन अब जैसे ही अत्यधिक बारिश सामान्य हो जाती है, तो संरचनाओं को फिर से बदलने की जरूरत होगी ताकि वे मौसम के दौरान बने रहें। बात सिर्फ इतनी सी है कि हमें जलवायु परिवर्तन के इस युग में न केवल बारिश की बल्कि बाढ़ के पानी की हर बूंद को जमा करने के लिए जरूरी योजना बनानी चाहिए।

बढ़ते तापमान पर सीएसई ने जताई चिंता, कहा जल सुरक्षा पर मंडरा सकता है गंभीर संकट

ये जलवायु परिवर्तन का युग है। जलवायु परिस्थितियों से बचाव के लिए किए गए उपाय ही भविष्य भी तय करेंगे। ये कहना है सेंटर फॉर साइंस एंड एनवायरनमेंट (सीएसई) की महानिदेशक सुनीता नारायण का। ये बातें उन्होंने "भारत के बड़े हिस्से में गर्मी की शुरूआत इतनी तेज गर्म लहर के साथ होने का क्या मतलब है?" सवाल का जवाब देते हुए कही है। उन्होंने विस्तार से बताया, मैं ऐसा इसलिए कह रही हूं क्योंकि हम सभी जानते हैं कि जलवायु परिवर्तन के प्रभाव गर्मी, चिलचिलाते तापमान और परिवर्तनशील और अत्यधिक बारिश के बारे में हैं। दोनों का जल चक्र के साथ सीधा संबंध है। इसलिए जलवायु परिवर्तन के बारे में पानी और उसका प्रबंधन होना चाहिए। सीएसई, जलवायु परिवर्तन, उप कार्यक्रम प्रबंधक, अवंतिका गोस्वामी ने कहा, भारत में 2021 की स्थिति दोहराई जा रही है, जब देश के कुछ हिस्सों में फरवरी की शुरूआत में तापमान 40 डिग्री सेल्सियस को छू गया था, और यह तब हुआ जब 2021 ला नीना का साल था, जिसमें प्रशांत जल धाराएं विश्व स्तर पर ठंडा तापमान लाने के लिए जानी जाती हैं। भारतीय मौसम वैज्ञानिकों ने सूचित किया है कि ग्लोबल वार्मिग ला नीना के इस प्रभाव की भरपाई करेगी। सीएसई के शोधकर्ता के अनुसार, बढ़ती गर्मी का जल सुरक्षा पर गंभीर प्रभाव पड़ता है। सबसे पहले इसका मतलब जल निकायों से ज्यादा वाष्पीकरण होना है। नारायण ने आगे कहा कि इसका मतलब है कि हमें न केवल लाखों संरचनाओं में पानी के भंडारण पर काम करने की जरूरत है, बल्कि वाष्पीकरण के कारण होने वाले नुकसान को कम करने की भी योजना बनानी है। ऐसा नहीं है कि वाष्पीकरण नुकसान पहले में नहीं हुआ हैं, लेकिन वाष्पीकरण की दर में अब बढ़ते तापमान के साथ वृद्धि होगी। सीएसई के शोधकर्ताओं के अनुसार, एक विकल्प भूमिगत जल भंडारण या कुओं पर काम करना है। भारत के सिंचाई योजनाकार और नौकरशाही काफी हद तक नहरों और अन्य सतही जल प्रणालियों पर निर्भर हैं, उन्हें भूजल प्रणालियों के प्रबंधन में छूट नहीं देनी चाहिए। गर्मी बढ़ने से मिट्टी की नमी सूख सकती है। यह जमीन पर और ज्यादा धूल कर देगा और इससे सिंचाई की महत्ता बढ़ेगी। भारत जैसे देश में जहां अभी भी अधिकांश अनाज वर्षा आधारित क्षेत्रों में उगाया जाता है। बारिश से सिंचित यह भूमि क्षरण को और तेज करेगा। इसका मतलब है कि जल प्रबंधन को वनस्पति योजना के साथ हाथ से जाना चाहिए ताकि मिट्टी की पानी धारण करने की क्षमता में सुधार हो सके, यहां तक कि तीव्र और लंबी गर्मी के समय में भी ऐसा होना चाहिए। तीसरा और स्पष्ट रूप से गर्मी पानी के उपयोग को बढ़ाएगी, जिसमें पीने और सिंचाई से लेकर जंगलों या इमारतों में आग से लड़ना शामिल हैं। हम पहले ही दुनिया के कई हिस्सों में और भारत के जंगलों में विनाशकारी जंगल की आग को देख चुके हैं। तापमान बढ़ने के साथ ही यह और बढ़ेगा। जलवायु परिवर्तन के साथ पानी की मांग बढ़ेगी, जिससे यह और भी जरूरी हो जाएगा कि हम पानी या अपशिष्ट जल को बर्बाद न करें। इतना ही नहीं, तथ्य यह है कि अत्यधिक बारिश की घटनाओं की बढ़ती संख्या के संदर्भ में जलवायु परिवर्तन पहले से ही दिखाई दे रहा है। इसका मतलब है कि हम बारिश को बाढ़ के रूप में आने की उम्मीद कर सकते हैं, जिससे बाढ़ के बाद सूखे का चक्र और भी तीव्र हो जाएगा। भारत में पहले से ही एक वर्ष में कम बरसात के दिन होते हैं। ऐसा कहा जाता है कि एक वर्ष में औसतन केवल 100 घंटे बारिश होती है। अब बारिश के दिनों की संख्या और कम हो जाएगी, लेकिन अत्यधिक बारिश के दिनों में वृद्धि होगी। इसका जल प्रबंधन की हमारी योजनाओं पर व्यापक प्रभाव पड़ा है। इसका मतलब है कि हमें बाढ़ प्रबंधन के बारे में और अधिक सोचने की जरूरत है न केवल नदियों के तटबंध के लिए बल्कि बाढ़ के पानी को अनुकूलित करने के लिए ताकि हम उन्हें भूमिगत और भूमिगत जलभृतों, कुओं और तालाबों में संग्रहीत कर सकें। इसका मतलब यह भी है कि हमें बारिश के पानी को बचाने के लिए अलग तरह से योजना बनाने की जरूरत है। उदाहरण के लिए वर्तमान में, महात्मा गांधी राष्ट्रीय ग्रामीण रोजगार गारंटी अधिनियम के तहत बनाए जा रहे लाखों जल ढांचे, सामान्य वर्षा के लिए डिजाइन किए गए हैं। लेकिन अब जैसे ही अत्यधिक बारिश सामान्य हो जाती है, तो संरचनाओं को फिर से बदलने की जरूरत होगी ताकि वे मौसम के दौरान बने रहें। बात सिर्फ इतनी सी है कि हमें जलवायु परिवर्तन के इस युग में न केवल बारिश की बल्कि बाढ़ के पानी की हर बूंद को जमा करने के लिए जरूरी योजना बनानी चाहिए।

Rising heat has severe implications for water security: CSE

The intense heatwave that has gripped large parts of India so early this summer is The intense heatwave that has gripped large parts of India so early this summer is proof that this is the age of climate change and it can have severe implications for water security, the Centre for Science and Environment said on Tuesday. Speaking on the occasion of World Water Day, CSE Director General Sunita Narain said climate mitigation has to be about water and its management. "What does this intense heat wave that has hit large parts of India so early this summer really mean? It means, especially today, as we mark the World Water Day, that this is the age of climate change. It also means that how we deal with our water in the coming days will determine whether we would survive such extreme climatic conditions. "We all know that climate change impacts are about increased heat and scorching temperatures, and about variable and extreme rain. Both have a direct correlation with the water cycle. Therefore, climate change mitigation has to be about water and its management," Narain said. India is witnessing a repeat of 2021 conditions, when temperatures touched 40 degrees Celsius as early as February in some parts of the country, said Avantika Goswami, deputy programme manager, climate change, CSE. "This was when 2021 was the year of the La Nia, the Pacific water currents that are known to bring cooler temperatures globally. Indian weather scientists have informed that global warming has offset this cooling effect of La Nia," Goswami said. CSE researchers pointed out that rising heat has severe implications for water security and to begin with, it would mean greater evaporation from water bodies. "It means that we need to work not just on storing water in millions of structures, but also plan for reducing losses due to evaporation. It's not that evaporation losses did not happen in the past, but the rate of evaporation will now increase with the soaring temperatures," CSE said. According to researchers, India's irrigation planners and bureaucracies have largely depended on canals and other surface water systems they should not discount the management of groundwater systems. Increased heat can also lead to drying up of moisture in soils, the CSE said, adding that it will make the land dusty and will increase the need for irrigation. In a country like India where the bulk of food is still grown in rain-fed regions, it will intensify land degradation and dust bowl formations. This means water management must go hand in hand with vegetation planning to improve the ability of soils to hold water, even in times of intense and prolonged heat, it said. The organisation cautioned that heat will drive up the use of water, from drinking and irrigation to fighting fires in forests or buildings. "We have already seen devastating forest fires rage in many parts of the world, and in the forests of India. This will only increase as temperatures go up. The demand for water will increase with climate change, making it even more imperative that we do not waste -- either water or wastewater," it said. CSE also said climate change is already showing up in terms of the increasing number of extreme rain events. "This means that we can expect rain to come as a flood, making the cycle of floods followed by droughts even more intense. India already has fewer rainy days in a year -- it is said that it rains for just 100 hours on average in a year. Now the number of rainy days will further go down, but extreme rainy days will increase," it said. "We needed to be obsessive about water and its management yesterday because water is the basis of health and wealth. But now we need to be more than obsessive. We need to be determined and deliberate. On this World Water Day in the age of climate change we need to know that the water agenda is the real make or break of our future" said Narain.

12 NCR cities among world’s 25 most polluted in 2021, Bhiwadi the worst

GURUGRAM: The dismal picture of air pollution in Delhi-NCR has been captured in a world air quality pollution report compiled by a Swiss firm, IQAir. A total of 12 NCR cities, including Delhi, Noida, Ghaziabad and Gurugram, are among the 25 most polluted places in the world, according to the survey that compared last year’s data with that of 2020. At an average of 106.2 ug/m3, Bhiwadi in Rajasthan was found to have the worst PM2.5 level last year. The other NCR cities on the list were Delhi (96.4 ug/m3), Ghaziabad (102 ug/m3), Noida (91.4 ug/m3), Faridabad (88.9 ug/m3), Baghpat (89.1 ug/m3), Rohtak (86.9 ug/m3), Greater Noida (87.5 ug/m3), Jind (84.1 ug/m3), Gurugram (83.4 ug/m3), Bulandshahr (80.8 ug/m3) and Meerut (80.6 ug/m3). download (1) The report showed that air quality in many of these cities had deteriorated since 2020. While Bhiwadi’s PM 2.5 concentration rose by 9.7 ug/m3 in 2021, that of Delhi surged by 12.3 ug/m3. Gurugram registered a rise of 8.1 ug/m3, Faridabad 5.6 ug/m3, Rohtak 12.5 ug/m3 and Jind 2.5 ug/m3. Despite breathing marginally better air, some of the NCR cities still found mention among the 25 most-polluted. While Bulandshahr registered a decline of 17.6 ug/m3 in PM2.5 level, that of Ghaziabad fell by 4.6 ug/m3. PM2.5 saw a dip of 2.9 ug/m3 in Noida, 2 ug/m3 in Greater Noida and 1.7 ug/m3 in Meerut. The PM2.5 levels in all these cities were way above the safety limits mandated by WHO, which is just 5 ug/m3. PM2.5, particulate matter consisting of fine aerosol particles measuring 2.5 microns or smaller in diameter, is one of the six routinely measured air pollutants across the world and is commonly accepted as the most harmful. It has been found to be a major contributing factor for conditions such as asthma, stroke, heart and lung diseases. Experts pointed out that the air quality in these cities deteriorated with the easing of restrictions on movement during the pandemic. “A comparison of the data of 2020 and 2021 clearly showed that after the restrictions on movement were lifted, we witnessed a rise in pollutants, particularly PM 2.5. As 2020 was spent mostly in lockdown, the PM2.5 concentration was less compared to 2021. We need to act fast to ensure that the air quality does not deteriorate further,” said Anumita Roychowdhury, executive director (res-earch and advocacy) at the Centre for Science and Environment. P. Raghavendra Rao, the Haryana State Pollution Control Board (HSPCB) chairperson, said they were working on a plan taking the entire air-shed into consideration. “Elements like clean energy, zero emission, increase in electric vehicles and improving cycle tracks are some of the measures that we are working on to lower the pollutants in the air. We have to take the entire air-shed of NCR into account while dealing with pollution,” he added. S Narayana, member secretary of HSPCB, said, “If we analyse the data, we can see that the share of PM2.5 was higher during the winter months. But between March and September, it was relatively lower. This may be because of local factors. We are working at various levels to curb air pollution. For most of the NCR cities, the trend is similar. It may be because of stubble burning and low wind movement during winter.”

Delhi most polluted capital in world, finds air report

The city is topping the list for the fourth consecutive year. Delhi topped a list of 92 capital cities in 2020, 85 such cities in 2019, and 62 such cities in 2018. In terms of annual average PM2.5 levels in 2021, Delhi ranked as the most polluted out of 107 capital cities in the world, according to the 2021 World Air Quality Report. The city is topping the list for the fourth consecutive year. Delhi topped a list of 92 capital cities in 2020, 85 such cities in 2019, and 62 such cities in 2018. The report is based on PM2.5 data from 6,475 locations in “117 countries, regions and territories around the world,” and is prepared by IQAir, a Swiss air quality technology company. On the list of capital cities, Dhaka followed Delhi in terms of the annual average PM2.5 concentration, while N’Djamena, the capital of Chad, was third on the list. The report said: “India was home to 11 of the 15 most polluted cities in Central and South Asia in 2021. Delhi saw a 14.6% increase in PM2.5 concentrations in 2021 with levels rising to 96.4 µg/m3 from 84 µg/m3 in 2020. No cities in India met the WHO air quality guideline of 5 µg/m3. In 2021, 48% of India’s cities exceeded 50 µg/m3, or more than 10 times the WHO guideline.” The report draws data from government-operated monitoring stations as well as privately-owned ones, and monitoring stations operated by institutions. According to the report, “Central and South Asia had some of the world’s worst air quality and was home to 46 of the world’s 50 most polluted cities” in 2021. In the Central and South Asia region — including India, Iran, Nepal, Pakistan, Sri Lanka, Bangladesh, Afghanistan and Tajikistan — Bhiwadi, in Alwar district, Rajasthan, was the most polluted regional city, with an average PM2.5 concentration of 106.2 50 µg/m3. This was followed by Ghaziabad with 102 µg/m3, and then Delhi with 96.4 µg/m3. Delhi’s annual average PM2.5 level in 2021 was higher than that in 2020, but lower than the 98.6 µg/m3 recorded in 2019, 113.5 µg/m3 in 2018, and 108.2 µg/m3 in 2017. The city’s PM2.5 level was highest in November (224.1 µg/m3) and lowest in September (30.2 µg/m3). Even at its lowest, the average concentration was about six times the WHO guideline of 5 µg/m3. Bhiwadi also topped the list of the ‘world’s most polluted cities’ in 2021 — 50 cities ranked in terms of PM2.5 levels. This was followed by Ghaziabad, and Hotan, China. Delhi was fourth on the list, while Noida was seventh with a PM2.5 level of 91.4 µg/m3, and Gurgaon was eighteenth with 83.4 µg/m3. Faridabad, Baghpat, Bulandshahr, Meerut, and Sonipat are other NCR areas that were on the list. Sources of PM2.5 “include internal combustion engines, power generation, industrial processes, agricultural processes, construction, and residential wood and coal burning. The most common natural sources for PM2.5 are dust storms, sandstorms, and wildfires,” the report stated. Anumita Roychowdhury, the executive director of Research and Advocacy at the Centre for Science and Environment, said, “We know this from the regulatory data in India that pollution is bouncing back after 2020 which was a hard lockdown. We then saw the reopening of the economy, and it is expected that the pollution will bounce back. The post-recovery period calls for stringent implementation of action across the National Capital Region. Time-bound implementation would be necessary to arrest the re-bound so that it doesn’t worsen.”

CSE: High temp may hit water security

Bathinda: Centre for Science and Environment (CSE) director general Sunita Narain has said that the intense heat wave that has hit large parts of the country so early this year clearly point towards the impact of climate change. “On World Water Day, it also points as how we deal with our water in the coming days will determine whether we would survive such extreme climatic conditions,” Narain added. “It is well known that climate changes are about heat - increase and scorching temperatures and about variable and extreme rain. Both have a direct correlation with the water cycle. The climate change mitigation has to be about water and its management,” Narain stated. CSE researchers point out that rising heat has severe implications for water security. To begin with, it would mean greater evaporation from water bodies. Says Narain: “It means that we need to work not just on storing water in millions of structures, but also plan for reducing losses due to evaporation. It is not that evaporation losses did not happen in the past, but the rate of evaporation will now increase with the soaring temperatures.” “Increased heat can also lead to a drying up of moisture in soil,” she added.

Rising temperatures has serious implications for water security: CSE

Speaking on the occasion of World Water Day, CSE Director General Sunita Narain said climate mitigation has to be about water and its management The intense heatwave that has gripped large parts of India so early this summer is proof that this is the age of climate change and it can have severe implications for water security, the Centre for Science and Environment said on Tuesday. Speaking on the occasion of World Water Day, CSE Director General Sunita Narain said climate mitigation has to be about water and its management. "What does this intense heat wave that has hit large parts of India so early this summer really mean? It means, especially today, as we mark the World Water Day, that this is the age of climate change. It also means that how we deal with our water in the coming days will determine whether we would survive such extreme climatic conditions. "We all know that climate change impacts are about increased heat and scorching temperatures, and about variable and extreme rain. Both have a direct correlation with the water cycle. Therefore, climate change mitigation has to be about water and its management," Narain said. India is witnessing a repeat of 2021 conditions, when temperatures touched 40 degrees Celsius as early as February in some parts of the country, said Avantika Goswami, deputy programme manager, climate change, CSE. "This was when 2021 was the year of the La Nia, the Pacific water currents that are known to bring cooler temperatures globally. Indian weather scientists have informed that global warming has offset this cooling effect of La Nia," Goswami said. CSE researchers pointed out that rising heat has severe implications for water security and to begin with, it would mean greater evaporation from water bodies. "It means that we need to work not just on storing water in millions of structures, but also plan for reducing losses due to evaporation. It's not that evaporation losses did not happen in the past, but the rate of evaporation will now increase with the soaring temperatures," CSE said. According to researchers, India's irrigation planners and bureaucracies have largely depended on canals and other surface water systems they should not discount the management of groundwater systems. Increased heat can also lead to drying up of moisture in soils, the CSE said, adding that it will make the land dusty and will increase the need for irrigation. In a country like India where the bulk of food is still grown in rain-fed regions, it will intensify land degradation and dust bowl formations. This means water management must go hand in hand with vegetation planning to improve the ability of soils to hold water, even in times of intense and prolonged heat, it said. The organisation cautioned that heat will drive up the use of water, from drinking and irrigation to fighting fires in forests or buildings. "We have already seen devastating forest fires rage in many parts of the world, and in the forests of India. This will only increase as temperatures go up. The demand for water will increase with climate change, making it even more imperative that we do not waste -- either water or wastewater," it said. CSE also said climate change is already showing up in terms of the increasing number of extreme rain events. "This means that we can expect rain to come as a flood, making the cycle of floods followed by droughts even more intense. India already has fewer rainy days in a year -- it is said that it rains for just 100 hours on average in a year. Now the number of rainy days will further go down, but extreme rainy days will increase," it said. "We needed to be obsessive about water and its management yesterday because water is the basis of health and wealth. But now we need to be more than obsessive. We need to be determined and deliberate. On this World Water Day in the age of climate change we need to know that the water agenda is the real make or break of our future" said Narain.

Ola de calor en la India muestra efectos del cambio climático

El Centro para la Ciencia y el Medio Ambiente (CSE) informó que inició una ola de calor que afecta a gran parte de India este verano y muestra los efectos del cambio climático. De acuerdo al portal web de Prensa Latina, este martes la directora del CSE, Sunita Narain, destacó que los impactos del cambio climático tienen que ver con el calor y las lluvias variables, extremas, y ambos a la vez tienen una correlación directa con el ciclo del agua. Por lo tanto, la mitigación del fenómeno tiene que estar relacionada con el agua y su gestión, explicó Narain. Los expertos del CSE señalan que el aumento del calor tiene graves consecuencias para la seguridad del agua en el país y se deberá trabajar no sólo en su almacenaje en millones de estructuras, sino también en la reducción de las pérdidas por evaporación. Los investigadores señalaron que una opción es trabajar en el almacenamiento de agua subterránea o en pozos. El aumento del calor también puede provocar una desecación de la humedad en los suelos y hará que la tierra se vuelva polvorienta y aumente la necesidad de riego. Vale destacar que en la India, donde la mayor parte de los alimentos se cultivan todavía en regiones de secano (regadas por la lluvia), se intensificará la degradación de la tierra y la formación de tazones de polvo. Ante lo expuesto, esto significa que la gestión del agua debe ir de la mano de la planificación de la vegetación para mejorar la capacidad de los suelos de retener agua, incluso en épocas de calor intenso y prolongado. / WIL/JML

भारत का सबसे कम प्रदूषण वाला शहर है सिलीगुड़ी, बिहार के सिवान और मुंगेर हैं शीर्ष पर

सिलीगुड़ी, मोहन झा। बीते सर्दियों के मौसम में देश के सभी क्षेत्रों में वायु प्रदूषक कणों का स्तर अलग-अलग तीव्रता के साथ बढ़ा है। हालांकि अधिकांश क्षेत्रों में पीएम 2.5 के स्तर का समग्र क्षेत्रीय औसत पिछली सर्दियों की तुलना में कम था, लेकिन कई क्षेत्रों में सर्दियों में होने वाले धूंध के चरणों में गंभीर वृद्धि दर्ज की गई। पड़ोसी राज्य बिहार का सिवान और मुंगेर देश का सबसे ज्यादा प्रदूषित शहर पाया गया है। वहीं देश के पूर्वोत्तर भारत का प्रवेश द्वार माना जाने वाला सिलीगुड़ी पूर्वी क्षेत्र का सबसे कम प्रदूषण वाला शहर पाया गया है। बल्कि पूर्वोत्तर भारत के मिजोरम की राजधानी आइजोल और मेघालय की राजधानी शिलांग देश के सबसे कम प्रदूषित शहर हैं। सीएसई ने किया विश्‍लेषण सेंटर फॉर साइंस एंड एनवायरनमेंट (Center for Science and Environment) ने वर्ष 2021-22 के सर्द मौसम के दौरान (15 अक्टूबर 2021 से 28 फरवरी 2022 तक ) पूरे देश के शीतकालीन वायु गुणवत्ता का विश्लेषण किया है। यह विश्लेषण केंद्रीय प्रदूषण नियंत्रण बोर्ड (सीपीसीबी) के आधिकारिक ऑनलाइन पोर्टल सेंट्रल कंट्रोल रूम फॉर एयर क्वालिटी मैनेजमेंट द्वारा उपलब्ध रियल टाइम डाटा (15 मिनट का औसत) पर आधारित है। यह डाटा 26 राज्यों और केंद्र शासित प्रदेशों के 161 शहरों में फैले कंटीन्यूअस एंबिएंट एयर क्वालिटी मॉनिटरिंग सिस्टम (सीएएक्यूएमएस) के तहत 326 आधिकारिक स्टेशनों से लिए गए हैं। सीएसई के रिसर्च एंड एडवोकेसी की कार्यकारी निदेशक अनुमिता राय चौधरी और अर्बन डाटा अनालिटिक्स लैब के प्रबंधक अविकल सोमवंशी के अनुसार पूर्वोत्तर मे पश्चिम बंगाल के सिलीगुड़ी में सर्द मौसम में सबसे कम प्रदूषण का औसत दर्ज किया गया। बल्कि राज्य के कोलकाता, हावड़ा, आसनसोल, दुर्गापुर, हल्दिया और सिलीगुड़ी मे प्रदूषण का औसत 21 और पीक 27 प्रतिशत तक की गिरावट दर्ज की गई है। श्रीमद् भागवत कथा के पावन अवसर पर निकाली गई शोभा यात्रा। जागरण फोटो। सिलीगुड़ी में श्रीमद्भागवत कथा के अवसर पर निकली भव्‍य शोभायात्रा, जानिए कथा का समय यह भी पढ़ें बिहार के सर्वाधिक छह शहर प्रदूषण में अव्‍वल सर्दियों में प्रदूषण के क्षेत्रीय प्रोफाइल से पता चलता है कि पूर्वी क्षेत्र भी दिल्ली-एनसीआर जितना ही प्रदूषित है। बिहार के 19 शहर व कस्बों का पीएम 2.5 का स्तर दिल्ली एनसीआर के समान ही था। देश के 10 सर्वाधिक प्रदूषित शहरों में बिहार के 6 शहर शामिल हैं। जिसमें सिवान और मुंगेर शीर्ष पर हैं। जिसका मौसमी औसत 187 μg/m³ और 182 μg/m³ मीटर था। वहीं मुजफ्फरपुर बिहार का एकमात्र शहर है, जहां मिश्रित प्रवृत्ति देखी गई है। यानि यहां सर्दियों के औसत में गिरावट आई है, लेकिन पिछली सर्दियों की तुलना में प्रदूषण में वृद्धि हुई है। भले ही बिहार के छोटे शहरों का मौसमी औसत एनसीआर के बड़े शहरों को टक्कर देता हो, लेकिन धूंध के चरणों के दौरान उनका चरम प्रदूषण तुलनात्मक रूप से कम रहा है। वास्तव में सर्दियों में प्रदूषण के उच्च स्तर वाले शहरों में बिहार के 13 शहर शामिल हैं। इस सूची में दिल्ली एनसीआर के 11 शहर थे। बिहार और एनसीआर के क्षेत्रों के बाहर शीर्ष 25 शहरों में एकमात्र शहर उत्तरी हरियाणा का हिसार शहर था। सुधार की आवश्‍यकता सीएसई की एग्जीक्यूटिव डायरेक्टर रिसर्च एंड एडवोकेसी अनुमिता रॉय चौधरी का कहना है कि “स्पष्ट रूप से शीतकालीन प्रदूषण की चुनौती सिर्फ बड़े शहरों या एक विशिष्ट क्षेत्र तक सीमित नहीं है। यह एक व्यापक राष्ट्रीय समस्या है। जिसके लिए राष्ट्रीय स्तर पर तत्काल और सुमुचित कार्रवाई की आवश्यकता है। इसके लिए वाहन, उद्योग, बिजली संयंत्र और अपशिष्ट प्रबंधन, जैसे प्रदूषण के प्रमुख क्षेत्रों में वार्षिक वायु प्रदूषण वक्र और दैनिक प्रदूषण तीव्रता को मोड़ने के लिए त्वरित सुधार और कार्रवाई की आवश्यकता है।

Intense Heat Wave Hits Large Parts of India Early This Summer. What Does This Really Mean?

India is witnessing a repeat of 2021 conditions, when temperatures touched 40 degrees Celsius as early as February in some parts of the country, said Avantika Goswami, deputy programme manager, climate change, CSE. It is just March, but an intense heatwave has already gripped large parts of India. And, it is quite clear that this early summer in India is proof that this is the age of climate change and it can have severe implications for water security, said the Centre for Science and Environment. Speaking on the occasion of World Water Day, CSE Director General Sunita Narain said climate mitigation has to be about water and its management. Narain said, “It means that this is the age of climate change; it also means that how we deal with our water in the coming days will determine whether we will survive such extreme climatic conditions.” “I am saying this because we all know that climate change impacts are about heat — increased and scorching temperatures — and about variable and extreme rain. Both have a direct correlation with the water cycle. Therefore, climate change mitigation has to be about water and its management,” Narain elaborated.
