Good Food Challenge : भारत में शुद्ध भोजन जुटाना लोगों के लिए कैसे बनी चुनौती? एक रिपोर्ट में हुआ खुलासा

Good Food is Challenge : एक ताजा रिपोर्ट में खुलासा हुआ है कि देश के 71 फीसदी लोग शुद्ध आहार का प्रबंध (Good Food is Challenge) करने में असमर्थ हैं। ऐसें में लोगों को जैसा-तैसा भोजन कर दिन काटना पड़ रहा है, जिससे वे असमय ही काल के गाल में समा जा रहे हैं। एक सर्वे रिपोर्ट में जो परिणाम सामने आये हैं उसके अनुसार अधिकतर भारतीय भोजन का खर्च नहीं उठा सकते हैं और इस कारण (Good Food is Challenge) खराब भोजन का सेवन करके गंभीर बीमारियों से ​ग्रसित हो जाते हैं और उचित इलाज के अभाव में उनकी मौत तक हो जाती है। इस रिपोर्ट में यह भी दावा किया गया है कि औसत भारतीयों की थाली से पौष्टिक भोजन के रूप में मान्य फल, दूध तथा हरी सब्जियां गायब हैं, ऐसे में उनका स्वास्थ्य पोषक तत्वों की कमी के कारण प्रभावित हो रहा है। सेंटर फॉर साइंस एंड एनवायरनमेंट (CSE) और डाउन टू अर्थ पत्रिका की ओर से जारी की गयी एक रिपोर्ट में कहा गया है कि 71 प्रतिशत भारतीय स्वस्थ आहार लेने में सक्षम (Good Food is Challenge) नहीं हैं। वहीं, वैश्विक औसत की बात करें तो यह आंकड़ा 42 प्रतिशत है। जबकि एक औसत भारतीय के आहार में आमतौर पर फल, सब्जियां, फलियां, नट्स और साबुत अनाज की कमी होती है। एक सामन्य भारतीय के आहार से मछली, डेयरी और रेड मीट भी बहुत कम मात्रा में शामिल है, शाकाहारी को प्राथमिकता देने वाले प्रदेशों में तो यह लगभग नगण्य है। पोषक तत्वों की कमी के कारण इन बीमारियों का शिकार हो रहे हैं लोग रिपोर्ट में यह बात भी निकलकर सामने आयी है कि खराब आहार लेने के कारण (Good Food is Challenge) लोग गंभीर बीमारियों का शिकार हो जाते हैं। रिपोर्ट के अनुसार, सर्वेक्षण में श्वसन संबंधी बीमारियों, मधुमेह, कैंसर, स्ट्रोक, कोरोना और हृदय से जुड़े रोगों का खतरा बना रहता है। सर्वे रिपोर्ट में आंकड़ों के साथ ही शुद्ध भोजन का खर्च नहीं उठा पाने के पीछे की वजह भी बताई गई है। अधिकांश भारतीय इस वजह से भी शुद्ध भोजन का खर्च नहीं उठा सकते, क्‍योंकि उनकी आय इस अनुपात में नहीं है कि वे अपने खाने-पीने का ख्याल रख सके। दिन ब दिन बढ़ रही महंगाई के कारण उनके लिए खाने-पीने पर विशेष खर्च करना संभव नहीं है। वहीं दूसरी ओर पोषक तत्वों से परिपूर्ण खाद्य पदार्थों के बारे में आम आदमी के पास जानकारी का भी अभाव है। यही कारण है कि वे अच्छे खान-पान पर खर्च नहीं कर पाते हैं।

सीएसई की रिपोर्ट:देश के 56 में से 47 शहरों में 50% से कम लोगों का हेल्थ इंश्योरेंस, 2030 तक 100 फीसदी करने का लक्ष्य

देश की 25% आबादी स्वास्थ्य, शिक्षा और जीवनशैली के पैमानों पर गरीब है। सेंटर फॉर साइंस एंड एनवायरनमेंट (सीएसई) की रिपोर्ट के मुताबिक, बिहार राज्य में सर्वाधिक 51.91% गरीब हैं। 16 शहरों में हर चौथा व्यक्ति झुग्गी-झोपड़ी में रहने को मजबूर है। इनमें 6 राजधानियां हैं। रायपुर और हैदराबाद तो मुंबई से भी बदतर। केंद्र सरकार का लक्ष्य है- 2030 तक कोई भी झुग्गियों में न रहे। देश में किसानों की औसत मासिक आय 2012-13 में 6426 रु. थी, जो 2018-19 में 10218 तक पहुंच गई यानी 59% का इजाफा हुआ। सरकार ने 2022 तक दोगुनी आय का लक्ष्य रखा था। देश के 50% किसान कर्जदार हैं। हर किसान पर औसतन 74,121 रु. का ऋण है। आंध्रप्रदेश में 93% किसान कर्ज में हैं और प्रति किसान औसतन 2.45 लाख का कर्ज है, जो देश में सर्वाधिक। सीएसई की रिपोर्ट के मुताबिक, राजधानियों में सबसे अच्छी स्थिति चेन्नई की है। यहां 1443 का अनुपात है। विशाखापट्‌टनम में प्रति एक हजार पुुरुषों पर देश में सबसे ज्यादा 1997 महिलाएं हैं। 16 शहरों में प्रति एक हजार पुरुषों पर 1000 से ज्यादा महिलाएं हैं। केंद्र सरकार का लक्ष्य है कि 2030 तक देश में लिंगानुपात 100% होना चाहिए। -71% को स्वस्थ आहार नहीं

Cities high on toxic air this summer

The summer of 2022 one of the hottest in India’s recorded history witnessed widespread increase in the level of ozone gas at ground level, making the air in metro cities more toxic, says a latest analysis. Termed ‘ozone exceedance’, the phenomenon refers to above-normal ozone concentration at ground level.According to latest air quality analysis by the Centre for Science and Environment (CSE), Delhi-NCR is followed by Mumbai, Kolkata, Hyderabad, Chennai and Bengaluru in the list of metros having higher levels of ozone exceedance. Both Chennai and Bengaluru have longer durations of exceedance despite lower frequency compared to other metros. While Delhi-NCR recorded ozone exceedance on almost all days of this summer, Mumbai had 75 days of exceedance. The study warns that the issue can blow up as a major health crisis in the coming days. “Even before we could control the problem of particulate pollution, the toxic threat of ground-level ozone is catching up with us. Despite the warning signs, this problem has not attracted adequate policy or public attention for mitigation and prevention. Inadequate monitoring, limited data and inappropriate methods of trend analysis have weakened the understanding of this growing toxic risk,” says Anumita Roychowdhury, executive director-research and advocacy, CSE. The assessment has traced trends during summer (March-May) between 2019 to 2022 May (up to May 30). The analysis is based on publicly available granular real time data (15-minute averages) from the CPCB’s official online portal Central Control Room for Air Quality Management. New Delhi and south Delhi neighbourhoods were the worst affected. The data also showed hourly peak levels up by 23 per cent compared to lockdown times. The 2020 State of Global Air report states that age-standardised rates of death attributable to ozone is among the highest in India. The seasonal eight-hour daily maximum concentrations have recorded one of the highest increases in India between 2010 and 2017.

Lethal Heatwave Additionally Ensuing In Ozone Exceedance And It is Making Delhi’s Air Poisonous

Elements of central and northwestern India are nonetheless within the grip of a warmth wave because the summer season of 2022 continues to interrupt information. On Friday, a warmth wave noticed the mercury breaching the 45-degree Celsius mark in elements of New Delhi. The Met Workplace issued a yellow alert, warning of a warmth wave at remoted locations within the capital on Saturday. Delhi Heat WaveBCCL Early warmth wave is inflicting ozone exceedance The persevering with warmth wave is extra dangerous information for the folks of Delhi. In keeping with a brand new research by the Centre for Science and Setting (CSE) the warmth waves are additionally resulted in widespread ozone exceedance, making the air of Delhi-NCR extra poisonous. The suppose tank’s evaluation is predicated on the publicly obtainable granular actual time information (15-minute averages) from the Central Air pollution Management Board of India’s(CPCB) official on-line portal Central Management Room for Air High quality Administration. Delhi Dust StormBCCL An ozone exceedance day happens when the each day most 8-hour common is 71 elements per billion (ppb) or increased. In Delhi-Nationwide Capital Area(NCR), the researchers captured information from 58 official stations. What the info stated The evaluation tracked exceedances at every station. Breach of the usual by even one station is taken into account exceedance by town. Days with a number of stations exceeding the usual signifies the severity of the spatial unfold and variety of folks uncovered. This yr, as a result of early onslaught of heatwaves, the spatial unfold of ground-level ozone began in March itself with April being the worst to date, the suppose tank stated. Delhi Dust StormBCCL The damaging build-up of ground-level ozone can occur anytime in the course of the yr, however it’s often in small pockets. For it to have wider spatial unfold, sizzling and sunny climate situations are wanted that are usually current in summer season, particularly throughout Might. However this yr, the frequency and unfold of ozone exceedance began early — within the month of March. “Floor-level ozone often exceeds the security commonplace on all days of summer season at some places in Delhi-NCR yearly. However the spatial unfold (variety of stations exceeding the usual throughout town) has been a lot increased this yr. On a median, 16 stations have exceeded the usual each day this March and April, which is 33 per cent improve from March and April 2021. Throughout 2020, when lockdowns had decreased the precursor gases wanted for formation of ground-level ozone, the quantity was right down to 10 stations each day,” the report stated. Dust StormBCCL Ozone exceedance not restricted to Delhi In keeping with the research, Delhi-NCR recorded ozone exceedance on nearly all days of this summer season. This nonetheless, will not be an issue that’s restricted to Delhi-NCR. The research discovered that Mumbai had 75 days of ozone exceedance whereas Kolkata-Howrah and Hyderabad registered 43 days every. What’s a warmth wave? A warmth wave is asserted when the utmost temperature is over 40 levels Celsius and not less than 4.5 notches above regular. Delhi Heat WaveBCCL A extreme warmth wave is asserted if the departure from regular temperature is greater than 6.4 notches, in accordance with the IMD. Based mostly on absolute recorded temperatures, a heatwave is asserted when an space logs a most temperature of 45 levels Celsius. A extreme warmth wave is asserted if the utmost temperature crosses the 47-degree Celsius mark.

As ozone levels rise, the air in Hyderabad becomes toxic

Recent reports suggest that Hyderabad’s air has become toxic due to the rising levels of ground-level ozone gas this summer. According to the Centre for Science and Environment (CSE), Delhi-NCR, Mumbai, Kolkata, Hyderabad, Chennai and Bengaluru have experienced ‘ozone-exceedance’, which is a phenomenon whereby ozone concentrations increase at ground level above normal levels. During the summer between March 2019 and May 2022, the assessment was conducted. On all days of summer, Delhi-NCR recorded ozone excess whereas Chennai and Bengaluru recorded longer durations. A total of 75 and 43 days of ozone excess were observed in Mumbai and Kolkata, respectively. During the current summer season, Hyderabad recorded 43 days of ozone exceedance, as temperatures in the city exceeded 40 degrees Celsius multiple times. “The toxic threat of ground-level ozone is catching up with us even before we could control particulate pollution. Despite the warning signs, mitigation and prevention of this problem have not received adequate policy attention or public attention. It has been difficult to understand the growing toxic risk due to inadequate monitoring, limited data, and inappropriate methods of trend analysis,” says Anumita Roychowdhury, executive director of CSE’s research and advocacy department. CPCB’s official online portal Central Control Room for Air Quality Management provides publicly available granular real-time data (15-minute averages) for the analysis. The worst affected neighbourhoods were in New Delhi and south Delhi. Data also showed that hourly peak levels were higher during lockdown times by 23 per cent. It’s no surprise that India’s 2022 summer was one of the hottest on record, resulting in a widespread rise in ozone levels at ground level. India has among the highest age-standardised rates of deaths attributable to ozone, according to the 2020 State of Global Air report. Between 2010 and 2017, India’s seasonal eight-hour daily maximum concentrations have experienced one of the highest increases.

Deadly Heatwave Also Resulting In Ozone Exceedance And It's Making Delhi's Air Toxic

Parts of central and northwestern India are still in the grip of a heat wave as the summer of 2022 continues to break records. On Friday, a heat wave saw the mercury breaching the 45-degree Celsius mark in parts of New Delhi. The Met Office issued a yellow alert, warning of a heat wave at isolated places in the capital on Saturday. Early heat wave is causing ozone exceedance The continuing heat wave is more bad news for the people of Delhi. According to a new study by the Centre for Science and Environment (CSE) the heat waves are also resulted in widespread ozone exceedance, making the air of Delhi-NCR more toxic.

Early onslaught of heat wave worsens ozone pollution in Delhi: study

CSE analysis is based on real-time granular CPCB data. (Representational) New Delhi: The summer of 2022 – one of the hottest in history – witnessed a widespread overshoot of ozone, making the air of Delhi-NCR more toxic, according to an analysis conducted by the Center for Science and the environment (CSE). The think tank’s assessment is based on publicly available real-time granular data (15-minute averages) from the official online portal of the Central Pollution Control Board of India (CPCB) Central Control Room for Air Quality Management. In the National Capital Region of Delhi (NCR), researchers captured data from 58 official stations. The analysis tracked the exceedances at each station. Failure to meet the standard by a single station is considered an overrun by the city. Days with multiple stations exceeding the norm indicate the severity of spatial spread and the number of people exposed. This year, due to the early onslaught of heat waves, the spatial spread of ground-level ozone began in March itself, with April being the worst yet, the think tank said. See also Detroit health department recommends masks indoors as city hits high level of COVID-19 The dangerous buildup of ozone at ground level can occur at any time of the year, but it usually occurs in small pockets. For it to have a wider spatial distribution, it requires hot and sunny climatic conditions which are generally present in summer, especially in the month of May. But this year, the frequency and spread of ozone overshoot began early – in March. “Ground level ozone generally exceeds the safe standard every day of summer at some locations in Delhi NCR every year. But the spatial spread (number of stations exceeding the standard throughout the city) has been much higher this year.On average, 16 stations exceeded the standard daily in March and April, a 33% increase from March and April 2021. In 2020, when shutdowns had reduced the precursor gases needed to form of ground-level ozone, the number had fallen to 10 stations daily,” the report said.

Patparganj in East Delhi recorded the largest increase in the number of days exceeding the norm compared to the average for the past three years. It recorded a spectacular jump of another 68 days with overshoot. It was followed by Sector 116 of Noida and Mandir Marg, next to the President’s estate. Siri Fort and Bawana in Delhi recorded the biggest reduction in the frequency of exceedances compared to the previous three-year average. Their exceedances have decreased by more than 40 days this year. Gurugram Sector 51, Dwarka Sector 8 and Najafgarh were other places with maximum improvement. After Delhi-NCR which recorded ozone exceedances almost every day this summer, Mumbai, with 75 days of exceedances, was the second most affected metro. Kolkata-Howrah and Hyderabad recorded 43 days of exceedance each. Even though the number of exceedance days in Kolkata-Howrah has been lower than in Mumbai, its citywide concentration is 30% higher than in Mumbai for this summer season. See also Crowdsourcing a War: How Online Calling Brings Weapons to Ukraine The CSE said the complex chemistry of ozone makes it a difficult pollutant to track and mitigate. Ambient ozone at ground level is not emitted directly from any source. It is produced from complex interactions between NOx and volatile organic compounds (VOCs) emitted by vehicles, power plants, factories and other combustion sources. These undergo cyclic reactions in the presence of sunlight to generate ground-level ozone. VOCs can also be emitted from natural sources, such as plants. This highly reactive gas has serious health consequences. People with respiratory disorders, asthma, chronic obstructive pulmonary disease, and especially children with premature lungs and the elderly are at serious risk. It can inflame and damage the airways, make the lungs susceptible to infection, worsen asthma, emphysema and chronic bronchitis, and increase the frequency of asthma attacks leading to increased hospitalizations.

Delhi rains: दिल्ली एनसीआर में गर्मी के साथ प्रदूषण ने भी बरपाया ‘कहर’, हवा में ओजोन का स्तर कई गुना बढ़ा – delhi weather today, delhi tempeture heatwave 45 digree celsius, increased level of ozone gas

नई दिल्ली: दिल्ली-एनसीआर में ओजोन गैस का स्तर कई गुणा बढ़ गया है। सीएसई (सेंटर फॉर साइंस एंड एनवायरमेंट) ने ओजोन को लेकर अपना विश्लेषण जारी किया है। दिल्ली-एनसीआर के बाद 6 बड़े शहरों की बात करें तो मुंबई दूसरे नंबर पर है। इसके बाद कोलकाता, हैदराबाद, चेन्नै और बैंगलुरू का नंबर आता है। सीएसई की एक्जीक्यूटिव डायरेक्टर अनुमिता रायचौधरी के अनुसार ओजोन ने समस्या बढ़ा दी है। अगर इस पर अभी से काम नहीं हुआ, तो आने वाले समय में यह गैस स्वास्थ्य के लिए गंभीर खतरा साबित हो सकती है। सीएसई के प्रिंसिपल प्रोग्राम मैनेजर विवेक चटोपाध्याय के अनुसार जैसे ही पीएम-10 और 2.5 का स्तर कम होने लगता है, नाइट्रोजन ऑक्साइड और ओजोन गैस बढ़ने लगती है। विश्लेषण की खास बातें इस साल गर्मी की शुरुआत के साथ ही ओजोन की समस्या भी मार्च में शुरू हो गई थी और अप्रैल में यह काफी खराब हो गई। मार्च और अप्रैल में दिल्ली-एनसीआर की 16 जगहों पर इसका स्तर पिछले साल की तुलना में 33 प्रतिशत तक अधिक रहा। 2020 के लॉकडाउन की तुलना में यह 23 प्रतिशत अधिक रहा। हालांकि पिछले साल एक दिन में औसत यह 4.6 घंटे तय मानकों से अधिक रहा था, लेकिन इस साल इसमें थोड़ी कमी आई और यह एक दिन में औसत 4.4 घंटे तय मानकों से अधिक रहा। navbharat times365 दिन में तैयार हो जाएगा सबसे आधुनिक चंद्रावल वॉटर ट्रीटमेंट प्लांट, जानें क्या-क्या होगा खास दिल्ली हवा जहरीली हो रही! साउथ दिल्ली के कर्णी सिंह शूटिंग रेंज में मार्च और अप्रैल के दौरान 85 दिन ओजोन का स्तर तय मानकों से अधिक रहा। इसके बाद जवाहर लाल नेहरू स्टेडियम, आरके पुरम, नेहरू नगर ओजोन से सबसे अधिक प्रभावित रहे। एनसीआर में ग्रेटर नोएडा के बाद फरीदाबाद में ओजोन का हॉट स्पॉट रहा। इतना ही नहीं, पूर्वी और मध्य दिल्ली में ओजोन के स्तर में सबसे अधिक इजाफा हुआ। पटपड़गंज में यह पिछले तीन सालों में सबसे अधिक 68 दिन तय मानक से अधिक रहा। इसके बाद इस क्रम में नोएडा सेक्टर-116, मंदिर मार्ग और प्रेजिडेंट इस्टेट का नंबर आता है। जबकि सीरीफोर्ट और बवाना में इसके स्तर में सबसे बड़ी कमी आई है। इसके बाद गुरुग्राम सेक्टर-51, द्वारका सेक्टर-8, नजफगढ़ का नंबर आता है। रात में भी ओजोन का स्तर रहा अधिक आमतौर पर ओजोन गैस सूर्यास्त के साथ कम हो जाती है, लेकिन इस गर्मी कुछ जगहों पर रात में भी इसका स्तर अधिक रहा। दिल्ली में ऐसी 7 जगह हैं, जहां इसका स्तर रात के समय भी 28 दिन तय मानकों से अधिक दर्ज किया गया। रात 10 से सुबह 2 बजे तक का यह आकलन है। इसकी सबसे अधिक मात्रा मुंडका, लोनी, वसुंधरा (गाजियाबाद) और नॉलेज पार्क-3 में रही। जनवरी में भी कुछ जगहों पर ओजोन का स्तर तय मानकों से अधिक दर्ज किया गया है। इस गर्मी में सिर्फ ओजोन प्रदूषण गंभीर स्तर पर नहीं रहा। बल्कि 2020 की गर्मियों की तुलना में एनओ-2 का स्तर 61 प्रतिशत और पीएम 2.5 का स्तर 76 प्रतिशत तक अधिक रहा। ओजोन को कंट्रोल करने के लिए अभी से काम करने की जरूरत है। इसके लिए गाड़ियों, इंडस्ट्री, पावर प्लंट और खुले में कूड़ा जलाने की घटनाओं को काबू करना होगा। प्रदूषण की पॉलिसी में पीएम-10 और पीएम 2.5 के साथ ओजोन के लिए भी नियम होने चाहिए। नैशनल क्लीन एयर प्रोग्राम में भी ओजोन को कंट्रोल करने के नियम शामिल हो।

During 2020, when lockdowns had reduced the precursor gases needed for formation of ground-level ozone, the number was down to 10 stations daily, the report said. Dr K S Shooting Range in south Delhi is the most chronically affected in Delhi-NCR. The ground-level ozone concentration exceeded the standard at this location for 85 days this March-May. JLN Stadium, RK Puram and Nehru Nagar followed close behind. Greater Noida is the major hotspot outside Delhi. Faridabad has least instances of ground-level ozone exceedances in the region, it said. Patparganj in East Delhi registered the highest increase in the number of days exceeding the standard as compared to the average of the last three years. It registered a dramatic jump of 68 additional days with exceedance. It was followed by Noida's Sector 116 and Mandir Marg, next to the President's Estate. Siri Fort and Bawana in Delhi registered the most reduction in the frequency of exceedances compared to average of previous three years. Their exceedances were down by over 40 days this year. Gurugram Sector 51, Dwarka Sector 8, and Najafgarh were other locations with the maximum improvement. After Delhi-NCR that recorded ozone exceedance on almost all days of this summer, Mumbai with 75 days of exceedance was the second-most impacted metro. Kolkata-Howrah and Hyderabad registered 43 days of exceedance each. Even though the number of exceedance days in Kolkata-Howrah has been lower than that of Mumbai, its citywide concentration is 30 per cent higher than in Mumbai for this summer season. The CSE said the complex chemistry of ozone makes it a difficult pollutant to track and mitigate. Ground-level ambient ozone is not directly emitted from any source. It is produced from complex interactions between NOx and volatile organic compounds (VOCs) that are emitted from vehicles, power plants, factories, and other combustion sources. These undergo cyclic reactions in the presence of sunlight to generate ground-level ozone. VOCs can also be emitted from natural sources, such as plants. This highly reactive gas has serious health consequences. Those with respiratory conditions, asthma, chronic obstructive pulmonary disease, and particularly children with premature lungs and older adults are at serious risk. This can inflame and damage airways, make lungs susceptible to infection, aggravate asthma, emphysema, and chronic bronchitis and increase the frequency of asthma attacks leading to increased hospitalisation.

The summer of 2022 — one of the hottest in history — has witnessed widespread ozone exceedance, making the air of Delhi-NCR more toxic, according to an analysis conducted by the Centre for Science and Environment (CSE). The green think tank’s assessment is based on the publicly available granular real time data (15-minute averages) from the CPCB’s official online portal Central Control Room for Air Quality Management. In Delhi-NCR, the researchers captured data from 58 official stations. The analysis tracked exceedances at each station. Breach of the standard by even one station is considered exceedance by the city. Days with multiple stations exceeding the standard indicates the severity of the spatial spread and number of people exposed. This year, due to the early onslaught of heatwaves, the spatial spread of ground-level ozone started in March itself with April being the worst so far, the green thinktank said. The dangerous build-up of ground-level ozone can happen anytime during the year, but it is usually in small pockets. For it to have wider spatial spread, hot and sunny weather conditions are needed which are generally present in summer, especially during May. But this year, the frequency and spread of ozone exceedance started early — in the month of March. Ground-level ozone usually exceeds the safety standard on all days of summer at some locations in Delhi-NCR every year. But the spatial spread (number of stations exceeding the standard across the city) has been much higher this year.
