Cabinet OKs enhanced climate action goals under Paris Agreement

NEW DELHI: Taking a step towards achieving India’s long-term goal of reaching ‘net zero’ emission by 2070, the Cabinet on Wednesday approved the country’s updated Nationally Determined Contribution (NDC) — climate action targets — committing to achieve about 50% cumulative electric power installed capacity from non-fossil-fuel-based energy resources by 2030 and to reduce emissions intensity (emission per unit of GDP) by 45% by 2030 from the 2005 level. India, however, makes its non-fossil-fuel-based (renewable as well as nuclear) electricity target conditional on international finance and technological support even as the country has, so far, made substantial progress on its earlier commitments largely financed from domestic resources. Making new pledges, the country clearly says that it will achieve its target of 50% cumulative electric power from non-fossil-fuel-based energy resources “with the help of transfer of technology and low-cost international finance, including from Green Climate Fund (GCF)”. The updated NDC is soon to be communicated to the United Nations Framework Convention on Climate Change (UNFCCC). India’s new commitment actually translates the ‘Panchamrit’, announced by Prime Minister Narendra Modi at COP26 in Glasgow, UK, into enhanced climate targets. It, however, prefers not to quantify its electricity goal in gigawatt-term (500GW) as announced earlier and remains silent on reduction of total projected carbon emissions by one billion tonnes from now to 2030. It, at the same time, clarified that 50% of ‘energy’ requirements from renewable energy by 2030, as stated in Glasgow, is to be counted in terms of non-fossil-fuel-based ‘electricity’ installed capacity. “In our view, we should have been as ambitious as we were in Glasgow,”said environmentalist Sunita Narain of Centre for Science and Environment (CSE). On the non-fossil-fuel-based electricity target, she said, “To meet 50% electricity from non-fossil by 2030, we will need to have 65-70% installed capacity of non/fossil sources... This is ambitious and will be expensive and this is why we need to make this conditional to international finance.” India’s updated NDC will be implemented by 2030 through programmes and schemes of relevant ministries/departments and with due support from states and UTs. Flagging India’s vision of “sustainable lifestyles” and “climate justice” to protect the poor and vulnerable from adverse impacts of climate change as a core theme of the updates, the NDC also emphasises on “citizen-centric approach” and mentions a need to have mass movement for ‘LIFE’ — Lifestyle for Environment — as a key to combat climate change. NDCs are basically the voluntary targets of countries under the Paris Agreement to collectively reach the goal of keeping the global average temperature rise well below 2° Celsius while making efforts to limit it to 1.5°C above pre-industrial (1850-1900) level. Though many countries have submitted their updated NDCs, analysis of their new targets shows the world continues to fall short to achieve its intended goal. India’s NDC, however, does not bind it to any sector-specific mitigation obligation or action. “India’s goal is to reduce overall emission intensity and improve energy efficiency of its economy over time and at the same time protect the vulnerable sectors of the economy and segments of our society,” clarified the government while making a statement on the updated targets. It, however, mentioned how its ‘net zero’ target of the Railways by 2030 alone will lead to a reduction of emissions by 60 million tonnes annually.

Heatwaves Rising During Monsoon For Past 2 Decades, But Related Deaths Fall: Govt

The All India mean temperature was recorded at 27.9 degrees Celsius in 2001 and had settled at 28.4 degrees Celsius in 2021 During the monsoon season, the average temperature in India has been increasing over the past two decades leading to various weather events across the country, the Earth Sciences Minister Jitendra Singh informed Lok Sabha earlier in the day. The minister also pointed out that the farming activities were delayed due to the change in the rainfall pattern this year. "It is a fact that the annual temperature is increasing globally and the impact of the same is reflected in the increase in severe weather occurrence in various parts of the globe, including India," Singh said in a written reply during the Parliament session in lower house, news agency PTI reported. The All India mean temperature was recorded at 27.9 degrees Celsius in 2001 and had settled at 28.4 degrees Celsius in 2021, Singh said adding that the All India Mean Temperature had recorded a high of 28.6 degrees Celsius in 2019. While responding to separate question in Lok Sabha, Singh also cited a recent climate assessment report of the Ministry of Earth Sciences which revealed that the tropical Indian Ocean was warming rapidly over the recent decades. "The average basin-wide sea surface temperature (SST) is warming at a rate of 0.15 degrees Celsius per decade during 1951-2015. During the same period, globally averaged SST warmed at a rate of approximately 0.11 degrees Celsius," Singh said. "Owing to this rapid warming, the sea level in the Indian Ocean was observed to be rising at a rate of 1.06-1.75 mm per year during the last century (1874-2004) and approximately 3.3 mm per year in the recent decades (1993-2015), which is in a similar range of the mean sea level rise," PTI quoted Singh as saying. The government also noted that temperatures in India have surged during the monsoon season and the country might see more frequent heatwaves in the day to come. However, it said that deaths due to heatwaves came down significantly in the recent past. India has recorded its hottest March in more than a century. Last month, the Centre for Science and Environment (CSE) analysis based on India Meteorological Department (IMD)’s long-term data revealed that June to September monsoon season has been 0.3-0.4 degrees Celsius hotter than pre-monsoon seasons in the decade from 2012 to 2022.

पेरिस समझौते के तहत कैबिनेट ने जलवायु कार्रवाई लक्ष्यों को ठीक किया | भारत समाचार ,

नई दिल्ली: 2070 तक ‘शुद्ध शून्य’ उत्सर्जन तक पहुंचने के भारत के दीर्घकालिक लक्ष्य को प्राप्त करने की दिशा में एक कदम उठाते हुए, अलमारी बुधवार को देश के अद्यतन राष्ट्रीय स्तर पर निर्धारित योगदान को मंजूरी दी (एनडीसी) – जलवायु कार्रवाई लक्ष्य – 2030 तक गैर-जीवाश्म-ईंधन-आधारित ऊर्जा संसाधनों से लगभग 50% संचयी विद्युत शक्ति स्थापित क्षमता प्राप्त करने और 2005 के स्तर से 2030 तक उत्सर्जन तीव्रता (जीडीपी की प्रति इकाई उत्सर्जन) को 45% तक कम करने के लिए प्रतिबद्ध है। . हालाँकि, भारत अपने गैर-जीवाश्म-ईंधन-आधारित (नवीकरणीय और साथ ही परमाणु) बिजली लक्ष्य को अंतरराष्ट्रीय वित्त और तकनीकी सहायता पर सशर्त बनाता है, भले ही देश ने अब तक घरेलू संसाधनों से बड़े पैमाने पर वित्तपोषित अपनी पिछली प्रतिबद्धताओं पर पर्याप्त प्रगति की है। . 207 (1) नई प्रतिज्ञा करते हुए, देश स्पष्ट रूप से कहता है कि वह गैर-जीवाश्म-ईंधन-आधारित ऊर्जा संसाधनों से 50% संचयी विद्युत शक्ति के अपने लक्ष्य को प्राप्त करेगा “हरित जलवायु कोष सहित प्रौद्योगिकी के हस्तांतरण और कम लागत वाले अंतर्राष्ट्रीय वित्त की मदद से। (जीसीएफ)”। अद्यतन एनडीसी को जल्द ही जलवायु परिवर्तन पर संयुक्त राष्ट्र फ्रेमवर्क कन्वेंशन (यूएनएफसीसीसी) को सूचित किया जाएगा। भारत की नई प्रतिबद्धता वास्तव में ‘पंचामृत‘, प्रधानमंत्री द्वारा घोषित नरेंद्र मोदी COP26 in . पर ग्लासगो, यूके, संवर्धित जलवायु लक्ष्यों में। हालाँकि, यह पहले घोषित किए गए गीगावाट-टर्म (500GW) में अपने बिजली लक्ष्य को निर्धारित नहीं करना पसंद करता है और अब से 2030 तक कुल अनुमानित कार्बन उत्सर्जन में एक बिलियन टन की कमी पर चुप है। साथ ही, यह स्पष्ट किया कि 50 2030 तक नवीकरणीय ऊर्जा से ‘ऊर्जा’ आवश्यकताओं का%, जैसा कि ग्लासगो में कहा गया है, गैर-जीवाश्म-ईंधन-आधारित ‘बिजली’ स्थापित क्षमता के संदर्भ में गिना जाना है। “हमारे विचार में, हमें उतना ही महत्वाकांक्षी होना चाहिए जितना हम ग्लासगो में थे,” पर्यावरणविद ने कहा सुनीता नारायण विज्ञान और पर्यावरण केंद्र (सीएसई) के। गैर-जीवाश्म-ईंधन-आधारित बिजली लक्ष्य पर, उन्होंने कहा, “2030 तक गैर-जीवाश्म से 50% बिजली को पूरा करने के लिए, हमें गैर-जीवाश्म स्रोतों की 65-70% स्थापित क्षमता की आवश्यकता होगी … यह महत्वाकांक्षी है और महंगा होगा और यही कारण है कि हमें इसे अंतरराष्ट्रीय वित्त के लिए सशर्त बनाने की आवश्यकता है।” भारत के अद्यतन एनडीसी को संबंधित मंत्रालयों/विभागों के कार्यक्रमों और योजनाओं के माध्यम से और राज्यों और केंद्र शासित प्रदेशों के उचित समर्थन के साथ 2030 तक लागू किया जाएगा। अद्यतनों के मुख्य विषय के रूप में जलवायु परिवर्तन के प्रतिकूल प्रभावों से गरीबों और कमजोरों की रक्षा के लिए “टिकाऊ जीवन शैली” और “जलवायु न्याय” के भारत के दृष्टिकोण को चिह्नित करते हुए, एनडीसी “नागरिक केंद्रित दृष्टिकोण” पर भी जोर देता है और आवश्यकता का उल्लेख करता है ‘जीवन’ के लिए जन आंदोलन – पर्यावरण के लिए जीवन शैली – जलवायु परिवर्तन से निपटने की कुंजी के रूप में। एनडीसी मूल रूप से पेरिस समझौते के तहत देशों के स्वैच्छिक लक्ष्य हैं, जो सामूहिक रूप से वैश्विक औसत तापमान वृद्धि को 2 डिग्री सेल्सियस से नीचे रखने के लक्ष्य तक पहुंचते हैं, जबकि इसे पूर्व-औद्योगिक (1850-1900) स्तर से 1.5 डिग्री सेल्सियस तक सीमित करने का प्रयास करते हैं। हालांकि कई देशों ने अपने अद्यतन एनडीसी प्रस्तुत किए हैं, उनके नए लक्ष्यों के विश्लेषण से पता चलता है कि दुनिया अपने इच्छित लक्ष्य को प्राप्त करने के लिए लगातार पिछड़ रही है। हालांकि, भारत का एनडीसी इसे किसी क्षेत्र-विशिष्ट शमन दायित्व या कार्रवाई के लिए बाध्य नहीं करता है। “भारत का लक्ष्य समग्र उत्सर्जन तीव्रता को कम करना और समय के साथ अपनी अर्थव्यवस्था की ऊर्जा दक्षता में सुधार करना है और साथ ही साथ अर्थव्यवस्था के कमजोर क्षेत्रों और हमारे समाज के क्षेत्रों की रक्षा करना है,” सरकार ने अद्यतन लक्ष्यों पर एक बयान देते हुए स्पष्ट किया। हालांकि, यह उल्लेख किया गया है कि अकेले 2030 तक रेलवे के ‘शुद्ध शून्य’ लक्ष्य से सालाना 6 करोड़ टन उत्सर्जन में कमी आएगी।

What if we designed homes to stay cool?

Cities and homes are set to get hotter over the coming decades as a result of climate change, migration to urban areas, the Urban Heat Island Effect and the increasing use of air conditioners. Passive design techniques incorporated into residential building design can help keep the insides of homes cool, mitigating some of the need for active cooling by air conditioning. As buildings go taller, it increases the embodied carbon, because more concrete density is needed to go higher. Additionally, lifts, fire systems and other features are needed for tall buildings. Cooling designs in buildings also help reduce emissions as air conditioners are not required to run continuously. Imagine a residential complex in a city such as Indore or Surat in the year 2030. If it looks like the high-rises being built in these cities today, it will be a multi-storeyed structure towering over the city, filled with modular homes with thin concrete walls. People living in the higher storeys will tend to keep their windows shut despite the heat, because the wind will be so powerful that it will make their doors slam. Those living on the topmost floor will be uncomfortable because they will be heated from all sides and from above. The views will be sweeping, and large French windows will show them off: the city spread out beneath, barring the occasional spindly tower at eye-level. The homes will get hotter by the year. Thin concrete and glass are no guard against the subcontinent’s punishing summers. Each home will require air conditioning in order to be liveable, and those air conditioners will exude more heat into the city. An estimate by McKinsey projects a 40% probability of at least one heatwave occurring in these urban areas between 2025 and 2035. Temperatures in the summer in Indore have already gone as high as 44 degrees Celsius and Surat, despite being a coastal city, saw temperatures rise six degrees above normal this year. By 2030, places like Indore and Surat – which are already Smart Cities – will possibly become tier 1 cities, and in the decades after, megacities. “India is no stranger to heat. It has a long history, a public memory and practices for dealing with it,” wrote Chandni Singh, a climate change researcher at the Indian Institute for Human Settlements, Bengaluru, in the New York Times. What if some of those traditional practices to adapt to heat, could be applied to the homes we build now, for the people who migrate to these cities in hope of building better lives? What could those homes look like? Mongabay-India spoke to several architects and urban design experts to identify some of the ways in which residential buildings, in particular, can be made cooler – a set of techniques called ‘passive design’ because they do not require the expending of energy for cooling. The illustration of a possible design for such a residential building is based on existing research and inputs from experts. Shade, ventilate, insulate The apartment complex, with buildings designed to be cooler, will be designed for thermal comfort, a somewhat subjective measure, because people’s idea of comfort differs based on their own preferences, the context they are in, and their life experiences. “Thermal comfort is the comfort hours which you get inside your structure. This is without air conditioning or any mechanical cooling system,” says Rajneesh Sareen, Programme Director, Sustainable Buildings and Habitat Programme at the Centre for Science and Environment in New Delhi. What humans think is comfortable though, has remained largely unchanged, Sareen says. “Your materials and other science may have changed, but your understanding of wind and the breeze (too windy) remains the same. Your body understands those in a similar fashion.” The three main passive design elements that go into creating thermal comfort are shading, ventilation and insulation. Shading blocks direct heat from entering the home, while still allowing light. Ventilation allows air to flow through the home, ideally allowing (cooler) outside air to replace inside air at an optimal rate of 10 changes an hour. Insulation keeps the home from absorbing too much heat, while still staying comfortably warm when it’s cool outside. Illustration by Nithya Subramanian/Mongabay. Illustration by Nithya Subramanian/Mongabay. In the Indian subcontinent, which lies in the Northern Hemisphere, the sun travels directly overhead in the summer, and falls at an angle from the south in the winter. “In the summers the sun on the southern side is very high, so even if you have a simple chajja (overhang for shade), it prevents the sun from hitting the glass in the window. That’s enough for that. And then in the winters, the sun angle is low on the south. In the winters you require the sun, so that same chajja is not going to obstruct the sun in the winter. This is especially true of places in north India, and that works out pretty well,” says Saswati Chetia, an architect and associate director at Greentech Knowledge Solutions, who specialises in energy efficient building design. The Eastern sun, where it rises, is mild and provides light, so Sareen suggests keeping living and working spaces on that side, while cutting the Western sun as much as possible with shading and insulated walls. Ventilation is tricky because it requires the flow of wind through the house, but only when it’s cooler. You also don’t want too strong a wind. To achieve optimal air flow, window design becomes crucial. French windows allow large amounts of light in, but they are inefficient from a ventilation point of view, because at any given time, only half the entire window area can ever be opened. Windows that open inward or outward, on the other hand, allow more than 90% of the window to be opened. Chetia also points out another flaw with French windows: They contain too much glass, which is a poor reflector of heat. Large windows turn homes into greenhouses, effectively trapping in heat that you then need an air conditioner to cool down. She suggests switching to older fashioned windows that were half glass – to let in light – and half wood, or another material that blocks both heat and light. If the view is compelling enough to still merit a French window, a heat reflective coating on the glass or a shade on the window becomes advisable. Illustration by Nithya Subramanian/Mongabay. Illustration by Nithya Subramanian/Mongabay. Ventilation is also a major reason for limiting the height of the building to no more than four storeys. Studies of wind flows in cities show that higher storeys experience uncomfortably high wind speeds. Tall buildings laid out in rows also create wind tunnels within the city, altering the patterns by which air flows through the city, and affecting life on the ground. One issue with using outside air for ventilation in larger cities is air pollution. As Chetia points out, “In places like Delhi, we really need to work on getting our outside air right, so that we can use it. It’s a resource that is there, and you are just polluting that resource and you’re not able to use it. And for other cities, it’s that don’t pollute your air to that extent. If you are not able to use it, it will be disastrous.” Insulation is the third part of designing for thermal comfort and this is determined by the materials that are used to construct homes. Modern residential complexes are made with Reinforced Cement Concrete (RCC) that is moulded concrete set around a steel frame for strength. RCC walls are great for multistorey construction because each individual wall is strong enough to be load bearing. This means there is no need for special beams or a frame. RCC walls can also be very thin, which is a boon for higher constructions, because the walls are light. Making moulds for RCC walls is expensive and the cost can only be justified if the moulds are used over and over, in modular constructions in multistorey residential complexes. Using such modular walls saves on labour and increases the pace of construction, which is why RCC finds increasing favour in city construction. It also means there is more floor area since the walls are thinner – as thin as 15 cm – and flats are sold based on floor area. But thin walls also mean faster heat transfer from outside to inside. Concrete is a poor insulator, with twice the thermal conductivity of clay bricks, and almost thrice that of environmentally friendly but less strong materials like Autoclaved Aerated Concrete. “If I want to break it down to absolute basics, I would say don’t go high rise. You have to have high density, but low rise,” says Chetia. In the homes of the future, thicker, or better insulated walls might be the way to go. In older buildings like the Benares Hindu University building in Varanasi, the walls are up to 24 inches thick, allowing in even lesser heat during the day, but trapping in heat to release during cool nights. But that doesn’t mean modern homes need such thick walls. There are plenty of compromises that can be struck along the way. “So instead of trying to do a very thick material wall, what we try to do is use hollow blocks somewhere or use double walls which is a cavity wall. There are two layers of thin walls with this air gap in between, which helps in reducing the heat gain. So instead of building an 18 inch or 24 inch wall, you might be able to achieve the same comfort in 12 inches itself,” suggests Anurag Tamahankar, a senior architect at Biome Environmental Solutions, a design firm with a focus on ecology. This still requires a compromise though: if walls are thicker, floor area will be less, which means that the carpet area of the house becomes less, and that is the measure on the basis of which homes are sold. “Most of the time people think it’s very expensive to work on [passive design],” says Sareen. “Then you have to tell them that it’s not expensive. Even the design, which is 2% of total cost of the project, can eventually give you a lot of gains.” Many of the solutions, like building orientation or careful window design do not add to the cost of construction, but still provide a measure of thermal comfort. Whether these designs are scalable, is yet not established. Since real estate costs are high in urban areas, builders try to build high to maximise land usage, indicate experts. But passive design could be adapted in tier 2 cities which are still expanding, where land costs are still not entirely prohibitive and there is, perhaps, still time to reimagine how people live. In its current form, cities and homes are set to get hotter over the coming decades as a result of climate change, migration to urban areas, the Urban Heat Island Effect and the increasing use of air conditioners.

Passive design in the subcontinent There are several design ideas that have evolved in the Indian subcontinent that merit consideration when building the homes of the future. Such ideas can be divided by class and chronology, says Amita Baviskar, sociologist and Professor of Environmental Studies and Sociology and Anthropology at Ashoka University. In dense areas of Delhi like the walled city of Shahjahanabad, she explains that it was a combination of trying to deflect the direct rays of the sun while allowing for ventilation. The devices used would be thick walls, porches, verandahs, chajjas, roshandaans (high ventilators) above the doors, and central courtyards. “Most houses will be ground floor, one, two storeys, with an open terrace on top. And that open terrace again became the place to catch breezes, sleep out on summer nights, catch the sun in the winters and so on.” What the British brought was a style that she classes broadly as tropical architecture: “It’s colonialism meeting local climate, which was based on a very privileged access to a lot of space.” So such homes had large gardens, verandahs and extended overhanging roofs. Baviskar also notes that there are similarities between the worker-housing chawls of Mumbai and the homes in Shahjahanabad in the shared balconies, the corridors, and the architecture of the shared courtyard. Mughal architecture incorporated water channels and fountains in indoor spaces, which enhanced evaporation and thus, cooling. Tamilian and Keralite homes often have wrought iron gates and verandahs before the home, allowing for a transitional space between outside and inside that screens heat. Local building techniques like mud plastering and thatched roofs in Rajasthan would also reduce sun exposure. While it is useful to look to vernacular techniques for inspiration, Tamahankar points out that not all such ideas are practical anymore. “Many of the techniques which were there, they are not probably suited for our current lifestyle,” he says, pointing out that mud walls require re-plastering every year. There are other practical issues: the lack of skilled labour and raw materials for such vernacular design techniques, says Sareen. Chetia also points out that brick laying, for instance, requires a mason, and then someone to supervise the mason, all of which increases the labour cost. Prefabricated concrete brings this cost down. Still, the design cost at least is only about 2% of the entire cost of a project, as noted by Sareen, and smart design choices can result in considerable savings on cooling bills over time. Newer but established ideas like roof gardens and solar panels on the roof are also important. The solar panels screen plants on the roof from direct sun, and can power at least common areas in the apartment complex, resulting in further energy savings. The ‘cold crunch’ Only 8% of households in India had air conditioners in 2017 according to the India Cooling Action Plan, but that number is set to grow rapidly. The International Energy Agency estimates that Indians own 67 million AC units in 2022. By 2032, they project that this number will go up to 318 million units. Much of this air conditioning will be devoted to cooling homes in urban areas, which heat up faster than rural areas. Such a high demand for cooling will drive up electricity demand, resulting in what the IEA calls a ‘cold crunch’. The solutions for this are of course multi-fold: air conditioners should become more energy efficient, urban planning should be improved in order to avoid the Urban Heat Island effect, and the homes of the future need to be built for greater thermal comfort. That does not mean that many such homes won’t still require air conditioning, but their design will mean that the air conditioners can run for fewer hours, and at higher temperatures than otherwise.

While a dense and compact typology increases efficiency in terms of usage of land and distribution of services, a high-rise building may underperform on sustainability, affordability and adaptive comfort, notes a policy brief by Centre for Science and Environment. “Studies show that the taller a building, the higher are the emissions per square metre due to higher cement and steel load per unit area,” it notes. “Go beyond [ground + 4 storeys] and you are increasing your embodied carbon, because you require more concrete density to go higher, you require a lift, you require fire systems and all the extra stuff,” says Chetia, which is why she suggests keeping buildings high density, but low rise. Emissions are automatically reduced when buildings don’t require air conditioners to run continuously.

Pollution in rivers

The report published by Central Pollution Control Board (CPCB) and the data collected therein, is the guiding document to assess the pollution in various stretches of rivers in the country. CPCB in association with the State Pollution Control Boards (SPCBs)/ Pollution Control Committees (PCCs) monitors water quality of rivers and other water bodies in the country through a network of monitoring stations under National Water Quality Monitoring Programme (NWMP). Based on water quality monitoring results, pollution assessment of rivers has been carried out by CPCB from time to time. State-wise details of polluted river stretches are given at Annexure-I. It was informed by CPCB that the data published by Centre for Science and Environment (CSE) is not available with them as the Board was not involved in publication of the same by CSE. As per the report of Central Pollution Control Board (CPCB) of March, 2021, sewage generation from urban areas in the country is estimated at 72368 million litres per day (mld), against which available sewage treatment capacity available is 31841 mld. State/Union Territory (UT) wise details of sewage generation from urban areas and corresponding sewage treatment capacities available are given at Annexure-II. Cleaning/rejuvenation of rivers is an ongoing activity. It is the primary responsibility of the States/Union Territories (UTs) to ensure the cleanliness of water in the rivers within their jurisdiction. States and UTs are to ensure that the Urban Local Bodies and Industrial Units located in their jurisdiction carry out the treatment of sewage and industrial effluents to the prescribed norms before discharging into rivers and other water bodies, coastal waters or land to prevent and control of pollution therein. For conservation of rivers, this Ministry has been supplementing efforts of the States/UTs by providing financial and technical assistance for abatement of pollution in identified stretches of rivers in the country through the Central Sector Scheme of Namami Gange for rivers in Ganga basin and through the Centrally Sponsored Scheme of National River Conservation Plan (NRCP) for other rivers. Setting up of STP is one of the important components of these programmes. Proposals for pollution abatement works in the towns and cities along polluted river stretches are received from the States/UTs from time to time for consideration under NRCP and Namami Gange and sanctioned based on their prioritization, conformity with guidelines of these schemes/programs, availability of plan funds, etc. NRCP has so far covered polluted stretches on 35 rivers in 78 towns spread over 16 States in the country with the project sanctioned cost of Rs. 6,142 crore, and inter alia, a sewage treatment capacity of 2,745.70 million liters per day (mld) has been created. Under the Namami Gange programme, 374 projects, including 161 projects for sewage treatment of 5,015.26 mld and a sewer network of 5,134 km, have been sanctioned at a cost of Rs.31,098 crore. In addition, sewerage infrastructure is created under programs like Atal Mission for Rejuvenation & Urban Transformation (AMRUT) and Smart Cities Mission of Ministry of Housing & Urban Affairs. CPCB, SPCBs and PCCs monitor industries with respect to effluent discharge standards and take action for non-compliance under provisions of Environment (Protection) Act, 1986 and Water (Prevention & Control of Pollution), Act 1974. Steps taken by the Government to stop discharge of industrial effluents into rivers inter alia, include issuance of notification of specific discharge standards, revision of the criteria for categorization of industries and issuing directions to all SPCBs / PCCs to adopt the same, issuance of consent to establish/consent to operate by the SPCBs/PCCs, based on Comprehensive Environment Pollution Index (CEPI) critically polluted areas are identified to take necessary measures through time-targeted Action Plans, regular inspections of Grossly Polluting Industries (GPIs) by CPCB for compliance verification, installation of Online Continuous Effluent Monitoring System (OCEMS) for assessment of effluent quality and compliance status. In addition, the industries are encouraged to reduce their waste water generation by technological advancement, reuse/recycle of wastewater and maintain Zero Liquid Discharge (ZLD) where ever possible. As per the orders of NGT, regular review on implementation of action plans is undertaken in the States/UTs and also at Central level by Secretary, Department of Water Resource, River Development & Ganga Rejuvenation, Ministry of Jal Shakti, Govt. of India. This information was given by the Minister of State, for Jal Shakti, Shri Bishweswar Tudu in a written reply in Lok Sabha today. *****

Visit of an annual threat: Is there anything different this year about Air Pollution?

The world’s apex intergovernmental council by the name United Nations General Assembly has recently passed a resolution extending the scope of universal human rights to include an easy and affordable access to clean, green, healthy as well as sustainable environment. This has been deemed an important step in curbing triple problems: planetary struggle against climate change, biodiversity loss and pollution. As per the UNGA Spokesperson, this resolution is bound to “reduce environmental injustices, close protection gaps and empower people, especially those in vulnerable situations, including environmental human rights defenders, children, youth, women and indigenous peoples”. Meanwhile in one of the world’s top most polluted capital city Delhi, its Lieutenant Governor VK Saxena called a meeting in order to discuss Delhi’s acute air pollution problems only to grow severe in upcoming winter months. He, especially, gave due directions to the stakeholder agencies and institutions so that they can work effectively, in synchrony and without delay before the city succumbs to these hazardous conditions. Stressing on the need to wake up for a united prompt action required to limit air pollution, he called to curb industrial emissions like burning of electronic chips, discarding solid municipal waste, vehicular emissions and discussed a further aggravated approach using mist sprinklers for settling the particles floating in the air. What makes the air pollution so demanding and scary? Surpassing the covid numbers, outdoor air pollution has turned out to become the fifth largest killer in the country based on the findings of Global Burden of Disease report. This comes after high blood pressure and indoor air pollution as the first and second reason respectively for untimely deaths in India. However, the Global Burden of Disease (GBD) report is an outcome of a world-wide initiative taken in consonance with the World Health Organization (WHO). In global respect, GBD ranks air pollution within the top 10 killers and as sixth largest killer across South Asia. As per the Centre For Science and Environment (CSE), Respiratory and cardiovascular diseases are the prominent culprits for air pollution-induced premature deaths including “stroke (25.48%), chronic obstructive pulmonary disease (17.32%), ischemic heart disease (48.6%), lower respiratory infections (6.4%), and trachea, bronchus and lung cancer (2.02%)”. The most disturbing trend has been noticed in the developing Asia wherein nearly two-thirds of the death burden can be derived from this sort of pollution. As the region walks the path of economic development, increased migration and motorization, 712,000 deaths alone due to outdoor pollution occur in South Asia. This is utterly worrisome as this death toll is much higher than the total number of 400,000 deaths in European Union, Eastern Europe and Russia. Out of 180 cities being consistently monitored for SOx, NOx and PM10, only two cities in Kerala i.e., Malapuram and Pathanamthitta out of the whole Indian mainland could pass the criteria of low pollution for all air pollutants (still counts for pollution). If we are to believe a new study undertaken at Massachusetts by the Barr Foundation, air pollution has far-reaching public health consequences of air pollution varying on town-by-town basis. The study could find plethora of relevant diseases though also associating death as well as significant IQ loss and low-birthweight babies, irrespective of its inherent demography or income level though the highest rates were prevalent in most economically stressed and socially underserved cities and towns.

A win-win alternative

Long-term evidence on holistic benefits of organic and natural farming show that these are not only profitable and sustainable but also productive It's hard to fathom that just 3.8 million hectares (ha) — 2.7 per cent of the country's net-sown area — is under organic and natural farming despite two decades of government efforts to upscale the practices. The Union government passed its first policy on organic farming in 2005, and introduced the flagship Paramparagat Krishi Vikas Yojana (PKVY) in 2015-16. Some of the prime reasons that hinder the shift is a lack of conviction among policymakers; limited consensus among the scientific community in favour of organic and natural farming; and the tendency to evaluate the non-chemical agricultural practices only on the basis of yield. The Centre for Science and Environment (CSE), a Delhi-based non-profit, has recently consolidated long-term evidence on holistic benefits of organic and natural farming. It analysed the results of 89 scientific studies, conducted across the country over the last decade, and the findings of the government's own All India Network Project on Organic Farming (AI-NPOF) going on in 16 states since 2004. CSE researchers analysed these key aspects: Crop yield, cost of cultivation, income and livelihood, soil health and environment, and food quality. On yield Long-term trends of crop yield from the AI-NPOF experiment show that the organic approach is better than inorganic and is at par with integrated methods. Of the 504 times yield results recorded during 2014-19, some 41 per cent of the yields were highest with the organic approach, followed by 33 per cent with integrated. For vegetables, oilseeds and cereals, the yield with organic approach was better than integrated and inorganic. In pulses and spices, yield with integrated approach was higher than with organic or inorganic approach. In case of natural farming, crops like maize, groundnut, sugarcane, finger millet, soyabean, jowar (sorghum) and turmeric also show higher yields. The studies highlight the importance of organic and bio-inputs like farmyard manure, vermicompost, poultry manure, green manure, liquid biofertilizers, Jeevamrutha, Beejamritha, Ghanajeevamritha, Panchagavya and fish-protein hydrolysate. Some also find a positive role played by seed soaking with liquid manure, mulching and intercropping in organic farming. After switching to organic practices, crops such as wheat, maize, rice, cluster bean, sesame, cumin and psyllium husk take a few years to produce a comparable or more yield than inorganic, while crops like potato take a year, the findings show. On profit The AI-NPOF project shows that the cost of cultivation is higher with the organic approach than integrated. The CSE report explains that the high-cost is because organic and bio-inputs used in AI-NPOF are largely purchased from the market. Whereas, organic inputs cost is less if produced on-farm by farmers. Also Read - Countering evil designs Despite the high cost of cultivation at AI-NPOF's farms, net returns are highest in 63 per cent of cropping systems with an organic approach. Similarly, in the case of integrated approach, net returns are highest in 11 per cent cropping systems. Along with minimised cost of production and premium prices for the produce, incomes and profits under natural farming are higher than conventional farming. On an average, even without certification, produce from natural farming fetches twice the income of conventional farming. On soil health Healthy soils are the basis for healthy food production. And the AI-NPOF project shows that organic approach is better at ensuring soil macro- and micro-nutrients, organic carbon and rhizosphere microbiome. While mean organic carbon is highest in 91 per cent cropping systems with organic approach, macronutrients like nitrogen, phosphorus and potassium are higher than inorganic approach in 42 per cent cropping systems. Soil micronutrients like iron, manganese, zinc and copper are also higher (by 76 per cent) with an organic approach. Though the integrated approach led to better results than inorganic in all cases, suggesting that lesser chemicals lead to better results in sustainability parameters, AI-NPOF results show that organic is even better than integrated in all except the cases of potassium, iron, manganese and bulk density. Soil health and fertility, macro and micro nutrients, soil organic carbon, soil enzymes, earthworms, soil respiration and microbial biomass increase after adoption of natural farming and Zero-Budget Natural Farming (ZBNF). Natural farming also improves overall resilience of crops to adverse climatic conditions and improves energy and water efficiency. It also has the potential to reduce carbon emissions. The studies highlight that ZBNF can help prevent over-extraction of groundwater, enable aquifer recharge and contribute to increasing water table. On food quality Food quality and nutrition with the organic approach are found to be better than inorganic, and slightly better than integrated. The AI-NPOF study for crops from five food groups (vegetables, oilseeds, pulses, spices and cereals) shows that in 67 per cent cases, results are higher with organic approach and in 64 per cent cases, they are higher with integrated approach. In 12 of the 15 crops, parameters were found highest with organic approach. Evidence collated from the other scientific studies show that the quality parameters like total carotenoids, total soluble solids, vitamin C, total sugars and lycopene are higher with the organic approach in vegetables and fruits. Organically grown maize, strawberries and marionberries have significantly higher (around 30 per cent) levels of cancer-fighting antioxidants. In the case of papaya, the quality parameters were higher with organic as compared to recommended dose of fertilisers. Organically grown taro had higher nutrient content. Organic farming also improved the physical attributes of vegetables such as cabbage, tomato and cowpea. Organically grown rice showed higher nutritive values than that grown with chemicals. Setting agenda It is important that the country's larger scientific community, trained in chemical-based agriculture, does not outrightly reject the evidence due to any bias and instead carefully review results of the work done by its scientific colleagues in different parts of the country. Benefits of organic farming related to profitability and sustainability strongly outweigh those with inorganic approaches. The existing programmes to support organic and natural farming should therefore be scaled up, expanded and properly funded. Develop a roadmap that sets the long-term agenda for adoption of agro-ecological approaches across different parts of the country in view of its holistic benefits such as nutrition, livelihood of farmers, natural resource conservation, biodiversity, resource efficiency, soil-health, disease resilience and mitigation of climate crisis. This roadmap should also consider mechanisms for incentivising farmers to adopt agro-ecological practices such as payments for ecosystem services, and specifically focus on supporting farmers during the transition to organic and natural farming through technical and financial support. There is an urgent need for a targeted, ambitious and well-funded nationwide programme to drive the change. This includes bringing together ministries and programmes; outlining the centre-state relationship in terms of funds, accountability and coordination; and establishing a vibrant market. Measures to adequately produce and make available quality organic fertilisers and biofertilizers at low cost should be the priority. To help the agriculture extension system support the transition on the ground, a capacity among extension officials should be developed. The organic certification process should be improved to make it farmer-friendly and low-cost. Measures should be taken to address the concerns about the PGS-India (Participatory Guarantee System of India) certification system and its implementation. An alternative certification that is simpler for farmers and trustworthy for consumers could be explored for well-connected local markets. States can be instrumental in helping farmers sell organic and natural produce by developing value chains, procuring produce and getting remunerative prices. DTE

SDG’s Headed For Failure

Two recent reports and other supporting data point towards the largescale failure of the 17 Sustainable Development Goals to deliver substantial change on the ground. It’s true that they have become a part of global discussion, but transformative change has eluded us so far as we approach the halfway mark since adopting the framework One hundred and ninety-three member states who have adopted Agenda 2030 of the United Nations, including India, need to get their act together fast if they intend to achieve the 17 Sustainable Development Goals (SDGs), and 169 targets defined under them, by the end of the decade. Two recent reports—one by the United Nations Economic and Social Council and the other published in Nature journal—suggest that most of the countries are way off-course in achieving the stated goals as we approach the halfway point since they were first adopted in September 2015. In fact, the import of the paper published in Nature on June 20, 2022, goes to the extent of predicting that the SDGs are doomed to fail for a number of reasons. The UN’s latest progress report paints an equally grim picture. “Today, we stand on the precipice of a critical moment. Either we fail to deliver on our commitments to support the world’s most vulnerable or together we turbo-charge our efforts to rescue the SDGs and deliver meaningful progress for people and the planet by 2030—stepping up our work to transform the international financial architecture; driving major economic transitions and renewing the social contract, and investing in data systems,” says the UN’s latest progress report. The two primary factors identified by the UN that have reversed decades of progress are the Covid-19 pandemic and Russia’s invasion of Ukraine that has sent massive shockwaves and disrupted the global supply chain of foodgrains. With Russia blocking Ukraine’s Black Sea port, export of millions of tonnes of wheat and other foodgrains from the beleaguered country has virtually come to a standstill. The impact of the pandemic has been particularly devastating, upending years of progress. “Global health systems were overwhelmed, and many essential health services were disrupted, posing major health threats and undermining years of progress fighting other deadly diseases,” says the report.“Furthermore, an additional 75 million to 95 million people will live in extreme poverty in 2022 compared to the pre-pandemic level. Billions of children significantly missed out on schooling and over 100 million more children fell below the minimum reading proficiency level and other areas of academic learning. This generation of children could lose a combined total of $17 trillion in lifetime earnings in present value.” SDGs Wedding cake_Wiki Commons The biosphere is the foundational layer of SDGs. It’s also the most vulnerable layer. Any adverse impact on this layer has a cascading effect on other goals (Photo: WIKI COMMONS) The war in Ukraine has triggered an unprecedented refugee and food crisis, which will have a long-lasting effect on the SDGs. “As of April 2022, more than 5.3 million refugees had fled Ukraine (most of who are women and children) and a further 7.7 million had been displaced inside the country. Another 13 million were stranded in conflict areas. Added to this, Russia and Ukraine are large producers and exporters of key food items, fertiliser, minerals, and energy. These two countries represent more than half of the world’s supply of sunflower oil and about 30% of the world’s wheat. At least 50 countries import at least 30% of their wheat from Ukraine or Russia, with 36 importing at least 50%, and most of them are African and least developed countries.” The closure of schools due to the pandemic has had a severe impact on SDG 4, which focuses on ensuring quality education and lifelong learning for all. “The COVID-19 outbreak has caused a global education crisis. Most education systems in the world have been severely affected by education disruptions and faced unprecedented challenges. School closures brought by the pandemic have had devastating consequences forchildren’s learning and wellbeing. It is estimated that 147 million children missed more than half of their in-class instruction over the past two years. This generation of children could lose a combined total of $17 trillion in lifetime earnings in present value. School closures affected girls, children from disadvantaged backgrounds, those living in rural areas, children with disabilities and children from ethnic minorities more than their peers,” notes the latest report. On gender equality, the report clearly states that the “world is not on track to achieve gender equality by 2030”. Though the pandemic has worsened the situation, chronic failures like policy implementation, weak laws and other systemic flaws remained unaddressed even before the global emergency. “Over 100 million women aged 25-54, with small children at home, are out of the workforce globally in 2020, including the more than 2 million who left the labour force due to the increased pressures of unpaid care work. Women’s health services faced major disruptions and undermined women’s sexual and reproductive health. And despite women’s effective and inclusive leadership in responding to COVID-19, they are excluded from decision-making positions.” The peer-reviewed paper published inNature—for which 61 scholars analysed 3,000 scientific studies—concluded that “the goals have had some political impact on institutions and policies, from local to global governance. This impact has been largely discursive, affecting the way actors understand and communicate about sustainable development. More profound normative and institutional impact, from legislative action to changing resource allocation, remains rare” and had “limited transformative political impact”. Interestingly, even as discussions around the SDGs continue to gain traction at various forums and levels, researchers have suggested that they have not found any substantial evidence that adoption of the goals has “advanced the position of the world’s most vulnerable countries in global governance and in the global economy”. The evidence on record highlights that the global legal and policy frameworks have not been altered that will allow such countries to have a greater say in global governance. However, on the brighter side, adoption of the SDGs has given a tool to civil society organisations to hold their governments to account, which to some extent has led to affirmative action on the ground. The authors of the paper have put the spotlight on some of the inherent contradictions that are built into these goals. The primary aim of the SDGs when they were framed was to ensure the long-term sustainability of life on the planet by creating or enhancing life-sustaining conditions. One such contradiction is maintaining economic growth while protecting the environment. As data and history show, these two objectives sit at opposite ends of the development matrix. Economic growth always results in increase in consumption, which in turn fuels production. Increased production leads to additional consumption of raw material and energy. This is a self-feeding cycle that has kept expanding throughout the industrial age. Therefore, to place them in the same basket ofSDGs is untenable. Science too points towards this inherent flaw in the SDG framework. “Many studies concur that the SDGs lack ambition and coherence to foster a transformative and focused push towards ecological integrity at the planetary scale,” note the authors of the paper. The reason for this lackadaisical approach is easy to understand. “There are indications that this lack of ambition and coherence results partially from the design of the SDGs, for example, global economic growth as envisaged in SDG 8 (notwithstanding regional development needs) might be incompatible with some environmental protection targets under SDGs 6, 13, 14 and 15.” The scientists note that national priorities often result in putting the various goals at odds with oneanother. “Experiences from the implementation of the SDGs in domestic, regional and international contexts provide little evidence of political impact towards advancing ecological integrity, as countries in both the Global South and the Global North largely prioritize the more socioeconomic SDGs over the environmentally oriented ones, which is in alignment with their long-standing national development policies.” A typical example of this inherent contradiction between economic development and ecological integrity built into the SDGs was highlighted in the March issue of Tatsat Chronicle. India has embarked on an ambitious project of producing 500 gigawatts (GW) of renewable energy as part of its energy transition strategy toward fulfilling the obligations under SDG 7.2. The article detailed how, in the race to increase generation of the green power to meet the target of 500 GW by the end of the decade, setting up mega solar power generation parks have become the order of the day. The case of the Solar Park spread over 14,000 acres in Jodhpur district of Rajasthan is a textbook example of conflicting SDGs. According to the publicly available information, this mega solar power generation complex has been developed on what has been officially classified as wasteland in the land records. In other words, this piece of real estate has no practical use. But a perusal of long-term district land records revealed that the so-called “wasteland” was used by the local people as pasture for their cattle and livestock, besides being the natural habitat for a variety of wildlife such as chinkara, blackbuck,jackals and jungle cats, to name a few. The case study highlighted the clash between SDGs 7.2 and 15, which states: Protect, restore, and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss. There is no doubt that the Bhadala Solar Park has resulted in biodiversity loss. Since the SDG framework is a set of guidelines, without any legally binding mechanism, this leaves them open to interpretations according to the convenience of nations, say the authors of the paper. “The SDGs are a non-legally binding and loose script, purposefully designed to provide much leeway for actors to interpret the goals differently and often according to their interests. Hence, many actors seem to use the SDGs for their own purposes by interpreting them in specific ways or by implementing them selectively.” The interim UN report too underlines the speed-breakers that are hampering energy transition that has been accorded priority in almost all European countries and in some in Asia, including India. “The impacts of climate change are already being felt across the world and COVID-19 further delayed the urgently needed transition to greener economies. While the economic slowdown and COVID-19 lockdowns led to the temporary reduction of CO2 emissions in 2020, global energy-related CO2 emissions rose by 6.0% as demand for coal, oil and gas rebounded with the economy in 2021. Based on current national commitments, global emissions are set to increase by almost 14% over the current decade, which could lead to a climate catastrophe unless governments, the private sector and civil society work together to take immediate action.” In India’s case, fulfilling Agenda 2030 is looking increasingly remote. According to the State of India’s Environment Report 2022, released by the Centre for Science and Environment in March this year, India’s ranking dropped from 117 last year to 120 this year on the 17 SDG indicators, slipping behind Bhutan, Nepal and Bangladesh. India’s overall SDG score was a mere 66 points out of a total of 100. Poor scores on some of the key parameters such as zero hunger, good health, elimination of poverty, gender equality, well-being, education for all and sustainable cities and communities, dragged down India’s ranking. Given the volume of evidence that is piling up with each passing year about the failure of the SDGs to make a meaningful normative and transformative impact, it’s clear that the framework suffers from serious design flaws. At the same time, given that it’s not backed by any legal mechanism, countries like India, and other developing nations, are bending it for their convenience, which in realistic terms won’t bring substantiative change.

The new children’s book ‘Women in Science’ by AdiDev Press featuring botanist Janaki Ammal and physicist Bibha Chowdhuri

“Celebrating women scientists and their incredible work is so important in our increasingly climate-risked world. A must-read for all.” ~ Sunita Narain, World renowned environmentalist. AdiDev Press’s ‘Learning To Be’ series, which released board books on the lives and philosophies of Indian saints Mahavira, Guru Nanak, and Buddha, is ready again with ‘Women in Science, an exciting new book series that includes four new board books with inspiring and true stories of four pioneering South Asian women in science. The set includes the following titles: Commitment with Bibha Chowdhuri (physicist), Courage with Anandibai Joshee (doctor), Passion with Aditi Pant (oceanographer), and Perseverance with Janaki Ammal (botanist). The story of these incredible women is sure to inspire and encourage many young children to pursue their dreams. Through these stories, children can explore how these outstanding women overcame their respective challenges to achieve pathbreaking success in their chosen fields. Discover courage with Anandibai Joshee, who overcame grief, fear, ill-health, and societal pressures to become the first Indian woman with a degree in western medicine. Discover commitment with Bibha Chowdhuri, the first Indian woman physicist who discovered sub-atomic particles called ‘meson’. Her discoveries lay the groundwork for the work of Nobel prize winner, C F Powell. Discover passion with Aditi Pant, who pursued her passion for science and adventure to become the first Indian woman oceanographer. She was one of the two women on the team that helped to build India’s first lab in Antarctica. Discover perseverance with Janaki Ammal, the first Indian woman botanist. Her pioneering work helped improve native plants and improved farmers’ lives. Authored by a Pune-based writer and poet Pervin Saket, using simple language and verse, the books talk about the inspiring journeys and hardships faced by these women in their lives which ultimately led to success in their respective fields. “It was very special for me to work on this series of books on ‘Women in Science’. These are fabulous, inspiring women who have made a twofold contribution to science and social progress. We need their stories to remind us to push further, overcome social barriers and fulfill our dreams,” said Pervin Saket. As an avid reader herself, Chitwan Mittal always felt the lack of representation of Indian culture and its people in children’s story books because most of the story books are inspired by western culture but as both her mother and grandmother were great storytellers, she used to hear numerous fascinating Indian stories which she could relate with and even while growing up this fascination never left. So, she decided to fill the cultural gap in the story books herself. “At AdiDev Press, we believe in the power of biographies to inspire and uplift, there is a great lack of inspirational biographies of South Asian women in the children’s segment and we feel that the stories of these pioneering women are so powerful that they must be shared with children, particularly girls, all over the world,” said Chitwan Mittal, Founder and Editorial Director of AdiDev Press.

Farm fires: Experts divided on cash incentive to farmers, ask why not use pusa-bio decomposer

Divided on the Punjab government's proposal to provide cash incentives to farmers to stop stubble burning, experts have asked why was the state not ramping up the use of Pusa bio-decomposer which was hailed as a cost-effective solution to farm fires by the Delhi government. Delhi Chief Minister Arvind Kejriwal had last week said the Punjab government has sent a proposal to the Commission for Air Quality Management to give cash incentive to farmers in the border state for not burning stubble. The proposal says that Delhi and Punjab should give Rs 500 each and the Centre should provide Rs 1,500. "Cash incentive is a temporary solution to the problem. Other methods such as using paddy straw in boilers and for manufacturing paper are cost-intensive. In-situ treatment is the only sustainable solution which will also help improve soil fertility," said Dipankar Saha, former chief of the Central Pollution Control Board's air lab. Vivek Chattopadhyaya, Principal Programme Manager, Clean Air, at the Centre for Science and Environment CSE) said financial support should be given to poor farmers who do not have access to subsidized machinery for in-situ management of paddy straw and collection centres for its use in industrial applications. "However, the financial support should be given at the community level and not to individual farmers," he said. This is not the first time Punjab will give cash incentives to farmers for not burning stubble. The governments of Punjab and Haryana had announced a bonus of Rs 2,500 an acre for small and marginal farmers in 2019 too, following the Supreme Court's suggestion to incentivise farmers to stop farm fires. However, a paucity of funds stalled the scheme. Only a few thousand farmers could avail the benefit. The Punjab government had even requested the Centre for financial assistance but to no avail. According to the Indian Agricultural Research Institute, Punjab had reported 71,304 farm fires between September 15 and November 30 last year and 83,002 farm fires in the corresponding period in 2020. Last year, the share of farm fires in Delhi's PM 2.5 pollution had peaked to 48 per cent on November 7.

Farm fires: Experts divided on cash incentive to farmers, ask why not use pusa-bio decomposer

New Delhi, Aug 1 (PTI) Divided on the Punjab government’s proposal to provide cash incentives to farmers to stop stubble burning, experts have asked why was the state not ramping up the use of Pusa bio-decomposer which was hailed as a cost-effective solution to farm fires by the Delhi government. Delhi Chief Minister Arvind Kejriwal had last week said the Punjab government has sent a proposal to the Commission for Air Quality Management to give cash incentive to farmers in the border state for not burning stubble. The proposal says that Delhi and Punjab should give Rs 500 each and the Centre should provide Rs 1,500. “Cash incentive is a temporary solution to the problem. Other methods such as using paddy straw in boilers and for manufacturing paper are cost-intensive. In-situ treatment is the only sustainable solution which will also help improve soil fertility,” said Dipankar Saha, former chief of the Central Pollution Control Board’s air lab. “Waste is wealth in today’s world. We should know how to use it (stubble)… how to convert it into fertilizer,” he said. State governments should work with the Indian Agricultural Research Institute as the degradation of paddy straw is possible through enzyme treatment. Now, they should explore methods to accelerate the enzyme treatment process so that stubble can be decomposed in a short period of time, Saha said. Paddy straw burning in Punjab and Haryana is a major reason behind the alarming spike in air pollution levels in the national capital in October and November. Farmers set their fields on fire to quickly clear off the crop residue before cultivating wheat and potato. Punjab generates around 20 million tons of paddy straw annually. Under a Centre-sponsored scheme, farm machinery is provided to farmers at a subsidised rate for in-situ management of the stubble. Farmers say a cash incentive can help them cover the cost of fuel used in operating the machinery. Environmentalist Bhavreen Kandhari said freebies can never be a solution to the problem of stubble burning. “I don’t think Punjab has any money to give to farmers. They had tried it earlier too, but they failed. The reality on the ground is different. The right thing to do is to immediately start work on a policy. Work on crop diversification,” she said. Kandhari asked why Punjab and Delhi are not investing in Pusa bio-decomposer which was hailed as a cost-effective solution to stubble burning by the AAP government in the national capital. She said “there is nothing substantial in the Pusa bio-decomposer” if the states are still going for cash incentive to stop stubble burning. In 2020, scientists at the IARI had come up with Pusa bio-decomposer, a microbial solution which can decompose stubble and turn into manure in 15-20 days. The Delhi government had provided it free to farmers in the capital to manage stubble in non-basmati rice fields in 2020 and 2021. The city government had also asked WAPCOS, a consultancy firm of the Union Ministry of Jal Shakti, to conduct an audit of the effectiveness of the bio-decomposer. According to the audit, 90 per cent of the participating farmers said the solution is highly effective. This prompted Chief Minister Arvind Kejriwal to urge the Centre to order free distribution of the decomposer in the neighbouring states. Sunil Dahiya, an analyst at Centre for Research on Energy and Clean Air, said there cannot be only one solution to farm fires and that states need to work on different options available, including cash incentives. “Pusa bio-decomposer cannot be considered a panacea to farm fires… Financial assistance will help farmers employ labour for stubble management… However, all other interventions such as farm equipment for in-situ management of paddy straw, use of stubble in organic agriculture and mulching and crop diversification should also continue,” he said. Asked whether providing cash incentives goes against the polluter pays principle, Dahiya said, “You think farmers are polluters and should be penalized for it. On the other hand, extensions are being provided to industries and thermal power plants to install technologies to curb emissions. This is not an ideal way to govern a state.” Vivek Chattopadhyaya, Principal Programme Manager, Clean Air, at the Centre for Science and Environment (CSE) said financial support should be given to poor farmers who do not have access to subsidized machinery for in-situ management of paddy straw and collection centres for its use in industrial applications. “However, the financial support should be given at the community level and not to individual farmers,” he said. This is not the first time Punjab will give cash incentives to farmers for not burning stubble.

As past targets fall short, the Delhi government encourages a solar power strategy

Despite substantial subsidies and other incentives provided by the Delhi government, solar power installations at homes have failed to pique the interest of home owners, with the city only managing to add 220 megawatts (MW) of power through this medium, less than one-tenth of the target of generating 2,762MW by the end of this year. Last February, the solar power generated by rooftop installations totaled 184MW. With the heat coming early this year, discoms anticipate that Delhi's peak power consumption would exceed 8,000MW for the first time this summer, putting a significant strain on the city's existing power infrastructure. Discoms stated there is ample awareness about solar rooftops, but they blamed Covid-19 for the installation lag. "In Delhi, the pandemic has had an impact on rooftop installations." Many group housing societies have been hesitant to allow solar merchants into their societies or locations over the last two years. "With infections fading, interest is returning," said a discom official who did not want to be identified. Experts, on the other hand, attribute the public's lack of interest to the lengthy installation and commissioning process for solar rooftops. Obtaining a NOC (no-objection certificate) from the discom and then filing an online application and the associated paperwork has proven to be labor-intensive and time-consuming. Delhi, which is urbanized and has a high income, was only able to install only 20% of the subsidised solar rooftop panels assigned to it, indicating that even subsidies are not being used. "The initial cost of installation continues to be a barrier for people," said Binit Das, deputy program manager, renewable energy, Centre for Science and Environment (CSE). In addition to lower costs and rebates for excess electricity generated, the Delhi government gives discounts of up to 20% for putting solar panels on rooftops of homes and businesses. According to discoms, Delhi already gives a better rate for surplus solar power — most states in the country have capped it at 2 per unit, while Delhi offers an average power procurement cost for surplus energy of 5 per unit. In June 2015, the National Solar Mission established a target of 2,762MW of solar electricity by 2022. With the scheme failing to attract enough users, the Delhi government's new solar policy, introduced by Delhi deputy chief minister Manish Sisodia during his Budget speech last month, is expected to include a variety of additional incentives and modifications. The Delhi administration has set a goal of 2,500MW of solar capacity in the next five years under it. "This is estimated to generate 10% of Delhi's yearly energy consumption," Sisodia said during his Budget speech last month, adding that the solar program will also create 40,000 new opportunities for construction workers, electricians, technicians, and engineers. According to a government official, the new solar strategy intends to increase the number of solar panels on Delhi roofs while also creating more jobs. "Lessons learned in recent years will be included into the new solar policy." "Over the last couple of years, Delhi has made a significant push toward electric vehicles and renewable energy," said a government official who did not want to be identified. According to BSES officials, the discom, which serves regions like as Saket, Vasant Kunj, Dwarka, Chattarpur, Sainik Farms, Karkardooma, Mayur Vihar, Patparganj, and Rohini, has seen over 4,000 solar rooftop installations with a combined load of more than 125MW. "Our Solar City concept has gotten positive feedback... The strategy benefits both consumers and the discom. The solar outreach program also educates people about the benefits of solar energy while assuring that the systems being built meet high quality standards. It also makes several financing alternatives available to clients," a BSES representative explained. One of the early success stories of the solar outreach was in Dwarka, where the discoms began installing solar panels in 2018 as part of a "Solarise Dwarka" project. According to KR Bhimrao, a resident of Shiv Bhole CGHS in Dwarka Sector 2, the society has a solar capacity of more than 100KW, which results in annual savings of more than 100,000 units across 60 families. "The savings are significant during the summer." "After observing a big reduction in our expenses, nearby societies began installing solar panels," he said. Over the previous three years, the Kalka CGHS community in nearby Sector 6 has also seen lower electricity prices. Residents claim that, with a combined installed capacity of more than 50KW, they produce excess electricity each year, resulting in discoms paying money to society at the end of the year. "We receive 5... for each surplus unit generated." So not only are the electricity bills lower, but extra output provides additional benefits at the end of each fiscal year if it is left over," explained Sujeet, a society resident. Each kilowatt (KW) of solar roofs may provide approximately 100-120 units of power per month, with experts estimating that the installation cost is normally recovered within 3.5 to 4 years. Solar panels necessary to generate one KW of power will cost between 60,000 and one lakh rupees. "Solar rooftop is becoming increasingly popular in Delhi, particularly in the domestic (residential) sector. The subsidy plan is to blame for this increase. However, subsidies alone are insufficient because there is a significant space constraint in residential areas in terms of roof size, which is slowing adoption "According to Dwijadas Basak, Chief-Commercial, Consumer Experience, and Social Impact Group at Tata Power Delhi Distribution Limited, areas such as Rohini, Pitampura, and Moti Nagar are gradually seeing increased demand for solar installation. Several obstacles According to Neeraj Kuldeep, program lead at the Council on Energy, Environment, and Water (CEEW), fulfilling states' ambitious solar power targets will necessitate a strong strategic push. "In order to increase the uptake of rooftop solar systems, the Delhi government should review the home electricity subsidy." Second, authorities should promote creative business models, such as the Solar Partners model, which uses extra roof space for solar power installations and provides clean electricity to consumers under virtual net-metering standards," Manjeet Kumar said. He also mentioned that a green tariff, which is a utility-approved power cost that permits users to get 100 percent of their electricity from renewable sources, might provide a much-needed push to rooftop solar installations. "Finally, the government may look at other developing potential, such as floating solar panels and lake revitalization," he said.

Bridging gaps

A farmer-producer organisation in Dantewada provides crucial market links for organic produce and helps naturally improve yields and incomes JUST LIKE any other entrepreneur, all a farmer needs is an assured market and a better deal. Akash Badave realised this as soon as he started working with tribal communities of Chhattisgarh's Dantewada district a decade ago. As a Prime Minister's Rural Development Fellow, he was assigned to help the district administration improve the livelihoods of marginal communities. Dantewada is in the spotlight for high level of malnutrition; for instance, as per the fifth round of the National Family Health Survey (2019-21), some 76 per cent of women aged 15-49 years in the district are anaemic. The national average for the same group is 57 per cent. Previous attempts to improve nutritional status of people in the district, by enhancing agricultural production through chemical fertilisers and pesticides, had few takers. "The chemicals killed all our earthworms and made our soil lifeless," says Rameshwar Yadav, a farmer in the district's Balud village. In 2012, the district administration decided to motivate farmers to turn to organic farming and to grow crops other than traditional paddy and millet varieties. But the exercise, says Badave, in-charge of the sensitisation programme, highlighted farmers' reluctance to grow more or new crops. Even if individual farmers grew surplus, there was a lack of market linkages for their harvest. The district, covered with dense forests and mineral-rich hills, has limited connectivity. Though the government procures certain crops at minimum support price (MSP), it benefits few. There is only one mandi for procurement of produce, which is out of reach for many. There is no system to procure organic produce. Down To Earth Gold Icon This story is from the August 01, 2022 edition of Down To Earth.

Why India Urgently Needs An Urban Stormwater Management Plan

Stormwater is a resource to conserve, but due to ill-equipped infrastructure, gushes into storm drains, sewer systems and drainage ditches, and causes soil erosion, silting, road damage, and property damage India went through a huge transition when Delhi, Mumbai, Chennai, Calcutta, Bangalore, Hyderabad, and other cities became hubs for economic activities and rapid urbanisation. The ever-burgeoning urban population demanded more robust infrastructure such as roads, houses, shopping complexes, etc. And unplanned development has brought about many big challenges; one of them being urban flooding due to poor stormwater management. Storm water is the huge amount of standing water produced after heavy rain/snow. When stormwater is absorbed by soil and filters through, it ultimately replenishes the aquifer. But due to high concretisation in many of our urban cities, this stormwater finds no direct ground to seep through. All the water gushes into storm drains, sewer systems and drainage ditches, and causes soil erosion, silting, road damage, property damage, by creating waterlogging in nearby low areas or ditches. In recent years, frequency of urban flooding has increased and is causing enormous socio-environmental hazards, major economic loss, along with the loss of lives as in the recent cases of Hyderabad and Assam. Delhi-NCR always faces long traffic snarls during heavy rains; one such infamous incident was Gurujam in Gurugram, the millennium city bordering Delhi that came to standstill for almost 20 hours due to traffic jams after heavy rainfall. A research paper published by Kapil Gupta from IIT-B on stormwater management in Mumbai records that the urban catchment of Kalyan, situated in North Mumbai which faces local flooding every year, political will more than engineering support to improve and that the existing stormwater drainage system requires. The Karnataka government report of 2021 on performance audit of stormwater management in Bangalore by AG India says that the city witnessed large-scale encroachment of lakes and drains, depletion of natural drainage system, change of land use, reduced vegetation cover, and loss of interconnectivity between water bodies that increased the runoff of stormwater. It was found that of the 1,452 water bodies in the early 1800s, only 194 remained by 2016 in the same area as there is no robust policy governing stormwater management. In the report by Centre for Science and Environment, The National Capital Territory (NCT) of Delhi is one of the largest urban spaces in the world and has a ground water table 40m below ground level in as much as 30 per cent of the city. As per the report, open spaces like parks have been identified in the city to prepare a sustainable stormwater management plan, keeping in mind factors such as post monsoon ground water level, geology, soil type and flood spots. The city is estimated to have 16,299 parks that have the capacity to harvest 3,423 million litres of annual runoff. The Environmental Impact Assessment Report 2021 by Greater Chennai Corporation that has built and maintained a stormwater drain network of 2,071 km, states that rainwater runoff gets drained through various stormwater drains and channels and reaches the sea across the city. Over the period, these drains’ carrying capacity reduced due to silt deposition. All such channels require desilting, and cleaning and disposing waste materials before the monsoon arrives, which puts a lot of stress on the municipal system. Historical records have shown several cases of extreme flooding in Chennai in 1943, 1978, 1985, 2002, 2005, and so on. Mainly all because of change in land use, disruption of natural gradient of stormwater channels, inadequacy, and imperativeness of local drainage infrastructure development in the city. According to a report published by Centre for Science and Environment for Hyderabad — the fastest-growing urban space in India after recording an annual 5 per cent population rise, the city has suffered several flooding episodes, the latest being in 2020 where 200mm rainfall happened overnight, resulting in a fury of runoff that submerged the entire city. Over 76 people died and it caused economic damage estimated at around 1,000 crores. The cause: limited stormwater channels propelled the runoff. Historically, Hyderabad had 400 lakes, and at least 48 flood absorbing tanks were built as part of stormwater management plan in 1912-29. Over time, most of them have been filled and used for various residential and commercial purposes. Currently, only 169 lakes exist as several water channels to carry stormwater have been encroached. Now the city’s stormwater management agenda is largely based on evacuation plans for flood-affected areas rather than storage or reuse of stormwater. All of these questions regarding collection, storage and reuse of stormwater are answered through proper stormwater management that must be based on urban, peri-urban and rural population density. Rapid urbanisation didn’t incorporate sustainable infrastructure plans. Unplanned or illegal land acquisition has led to encroachment of several kilometres of natural stormwater channels in such urban cities. Several water bodies like lakes, ponds, wells, etc., have been filled to fulfil various economic interests that essentially acted as runoff collectors. Most of our urban cities are concretised and are left with almost no space for rainwater absorption. Either stormwater drainage is missing in many such places, even if it’s there, most of the time it’s clogged with solid waste, silt, etc. To make the situation worse, many such channels are even connected with sewer pipelines. Even after mandatory rainwater harvesting system installation by group housing societies as per building code law, it’s not built or are used for different purposes or may even be symbolic and defunct. Quality of recharge water is also of huge concern and eventually such runoff mixed with mud and several chemicals and sewage finds its way to the nearby water body and over the period turns it into a ganda nalla (a dirty water channel). Most of the urban road system consisting of flyovers, underpasses and artery roads are not built with keeping runoff in mind. Every monsoon these low-lying areas get flooded after just one spell of heavy rainfall. Many such flooding hotspots like Delhi’s Minto Bridge make news every monsoon for getting submerged under storm water. Stormwater is not a liability to manage, rather a resource to conserve. As per a report, water demand in irrigation, domestic and industrial uses and other usage will be more than 1,000 cubic kilometres by 2025. If 80 per cent rainwater can be harvested by 2015, almost 33 per cent of such water requirements can be met with rainwater conservation. Not to mention the presence of other water resources. Sustainable urban designing would require rejuvenation of water bodies to increase their water holding and recharge capacity, increasing green cover in such areas by planting more trees, reviving old water storages, and creating awareness and willingness among stakeholders to save water. We must also consider the global contribution of climate change. Over the period, it has changed the rain pattern and caused unprecedented rainfall. Most of the urban infrastructure is not equipped to handle such eventualities, hence risk and vulnerability assessment is essential for urban stormwater management planning. For instance, stormwater drainage design in India was being carried out as per the Central Public Health and Environmental Engineering Organization (CPHEEO) manual guidelines, but only till 2019. Another part of the manual is guidelines for operation and maintenance. It’s important to note that having stormwater drainage channels but without regular and proper maintenance doesn’t serve the purpose. As per the report of the Sub-committee for Development of National Sustainable Habitat Parameters on Urban Storm water Management by the Ministry of Housing and Urban Affairs, it has been suggested that the various indices developed for assessment of drainage systems can be utilised for quantification of the sustainability of current drainage systems. After quantification, these indices will help to determine suitable drainage practices in specific wards, blocks, districts, or states, and finally the country. Such measures can be integrated in restoring the natural drainage system, rejuvenating lakes and ponds, and catchment areas, and thereby creating a sustainable stormwater management plan. It’s important to reiterate that stormwater is not a liability to manage, but a resource to conserve. Sustainable urban planning, innovative design solutions, right policies, strong stakeholder participation, awareness at large, and strong political will, can decrease water stress that most of our urban cities are currently facing. A holistic water security plan is the need of the hour.
