  • Public dashboard to track remediation of legacy Landfills

    landfill

    The remediation of all legacy landfills in India are in full swing and a public dashboard on the progress at 2,200 such sites is in the offing.

    What are Landfills?

    • A landfill site, also known as a tip, dump, rubbish dump, garbage dump, or dumping ground, is a site for the disposal of waste materials.
    • Some landfill sites are also used for waste management purposes, such as temporary storage, consolidation and transfer, or for various stages of processing waste material, such as sorting, treatment, or recycling.

    Threats posed by landfills

    Landfills have the potential to cause a number of issues. Infrastructure disruption, such as damage to access roads by heavy vehicles, may occur amongst others.

    1) Leachate

    • When precipitation falls on open landfills, water percolates through the garbage and becomes contaminated with suspended and dissolved material, forming leachate.
    • If this is not contained it can contaminate groundwater.

    2) Decomposition gases

    • Rotting food and other decaying organic waste create decomposition gases, especially CO2 and CH4 from aerobic and anaerobic decomposition, respectively.
    • Both processes occur simultaneously in different parts of a landfill.

    3) Other threats

    • Poorly run landfills may become nuisances because of vectors such as rats and flies which can spread infectious diseases.
    • The occurrence of such vectors can be mitigated through the use of daily cover.
    • Other potential issues include wildlife disruption due to occupation of habitat and animal health disruption caused by consuming waste from landfills, dust, odour, noise pollution, and reduced local property values.

    Why clear landfills?

    • Once removed, the sites would free up 15,000 acres of land.
    • For instance, the largest such landfill, in Mumbai, is spread over 300 acres and contains 2.60 crore tonnes of waste.
    • Delhi’s three landfills — Ghazipur, Bhalswa and Okhla — contain around 2.8 crore tonnes of waste.

    What is landfill remediation?

    The most common methods for the remediation of landfills include:

    • Excavation to recover recyclable materials
    • Capping to reduce leachate generation
    • Air sparging and soil vapor extraction to capture and remediate gases and
    • Pump-and-treat of the leachate-contaminated plume

    Significance of the portal

    • Through the portal, citizens would be able to track the progress of their cities’ action plans for remediation of legacy landfills.
    • The plans cover everything from remediation to the eventual reuse of the land.

  • Species in news: Neelakurinji

    neelakurinji

    As visitors keep pouring in to witness the blooming of neelakurinji on a vast area on the Kallippara hills at Santhanpara in Idukki, Kerala, an expert team has identified six varieties of the plant across the region.

    Neelakurinji

    • Kurinji or Neelakurinji (Strobilanthes kunthianus) is a shrub that is found in the shola forests of the Western Ghats in South India.
    • Nilgiri Hills, which literally means the blue mountains, got their name from the purplish blue flowers of Neelakurinji that blossoms only once in 12 years.
    • It is the most rigorously demonstrated, with documented bloomings in 1838, 1850, 1862, 1874, 1886, 1898, 1910, 1922, 1934, 1946, 1958, 1970, 1982, 1994, 2006 and 2018
    • Some Kurinji flowers bloom once every seven years, and then die. Their seeds subsequently sprout and continue the cycle of life and death.
    • The Paliyan tribal people living in Tamil Nadu used it as a reference to calculate their age.

    Threats to Neelakurinji

    • About 1,000 ha of forestland, grantis and eucalyptus plantations and grasslands have been destroyed in the fire.
    • These large-scale wildfires on the grasslands where Neelakurinji (Strobilanthes kunthiiana) blossomed widely last year after a period of 12 years could have wiped out all the seeds of the endemic flowers.
    • There are allegations that the areas coming under the proposed Kurinji sanctuary were set on fire with a motive to destroy the germination of Neelakurinji seeds.

  • Living Planet Report 2022: Wildlife populations decline by 69% in 50 years

    There has been a 69 per cent decline in the wildlife populations of mammals, birds, amphibians, reptiles and fish, across the globe in the last 50 years, according to the latest Living Planet Report by World Wide Fund for Nature (WWF).

    What is Living Planet Report?

    • The Living Planet Report is published every 2 years by the World Wide Fund for Nature since 1998.
    • It is based on the Living Planet Index and ecological footprint calculations.
    • The report is the world’s leading, science-based analysis, on the health of our planet and the impact of human activity.

    Issues raised by various versions of the report

    • The 2018 report found a “decline of 60% in population sizes” of vertebrate species overall from 1970 to 2014.
    • The tropics of South and Central America had an 89% loss compared to 1970.
    • The 2018 report calls for new goals post-2020 alongside those of the Convention on Biological Diversity, the Paris Climate Agreement and the Sustainable Development Goals.
    • The 2020 report says systemic changes are necessary to stop the destruction of global wildlife populations, including a complete overhaul of food production and consumption industries.
    • The 2022 report found that vertebrate wildlife populations have declined by an average of almost 70% since 1970, and attributes the loss primarily to agriculture and fishing.

    What is the Living Planet Index (LPI)?

    • The Living Planet Index (LPI) is a measure of the state of the world’s biological diversity based on population trends of vertebrate species from terrestrial, freshwater and marine habitats.
    • The LPI was adopted by the Convention of Biological Diversity (CBD) as an indicator of progress towards its 2011-2020 targets.
    • It can play an important role in monitoring progress towards the post-2020 goals and targets negotiated at COP15 this December.
    Features of the LPI Common misconceptions
    The LPI is shows the average rate of change in animal population sizes The LPI doesn’t show numbers of species lost or extinctions, although some populations do decline to local extinction
    Species and populations in the LPI show increasing, declining and stable trends Not all species and populations in the LPI are in decline
    About half of the species we have in the LPI show an average decline in population trend The LPI statistic does not mean that 69 per cent of species or populations are declining
    The average change in population size in the LPI is a decline of 69 per cent The LPI statistic does not mean that 69% populations or individual animals have been lost
    The LPI represents the monitored populations included in the index The LPI doesn’t necessarily represent trends in other populations, species or biodiversity as a whole
    The LPI includes data for threatened and non-threatened species – if it’s monitored consistently over time, it goes in! The species in the LPI are not selected based on whether they are under threat, but as to whether there is robust population trend data available

  • Eco-Sensitive Zones: SC may take up Kerala’s review

    The Supreme Court has indicated that it may consider taking up Kerala’s review of the Supreme Court’s judgment to have a 1km eco-sensitive zone ringing protected forests, national parks and wildlife sanctuaries across the country.

    What are the Eco-sensitive Zones (ESZs)?

    • Eco-Sensitive Zones (ESZs) or Ecologically Fragile Areas (EFAs) are areas notified by the MoEFCC around Protected Areas, National Parks and Wildlife Sanctuaries.
    • The purpose of declaring ESZs is to create some kind of “shock absorbers” to the protected areas by regulating and managing the activities around such areas.
    • They also act as a transition zone from areas of high protection to areas involving lesser protection.

    How are they demarcated?

    • The Environment (Protection) Act, 1986 does NOT mention the word “Eco-Sensitive Zones”.
    • However, Section 3(2)(v) of the Act, says that Central Government can restrict areas in which any industries, operations or processes or class of industries, operations or processes shall be carried out or shall not, subject to certain safeguards.
    • Besides Rule 5(1) of the Environment (Protection) Rules, 1986 states that central government can prohibit or restrict the location of industries and carrying on certain operations or processes on the basis of certain considerations.
    • The same criteria have been used by the government to declare No Development Zones (NDZs).

    Defining its boundaries

    • An ESZ could go up to 10 kilometres around a protected area as provided in the Wildlife Conservation Strategy, 2002.
    • Moreover, in the case where sensitive corridors, connectivity and ecologically important patches, crucial for landscape linkage, are beyond 10 km width, these should be included in the ESZs.
    • Further, even in the context of a particular Protected Area, the distribution of an area of ESZ and the extent of regulation may not be uniform all around and it could be of variable width and extent.

    Activities Permitted and Prohibited

    • Permitted: Ongoing agricultural or horticultural practices, rainwater harvesting, organic farming, use of renewable energy sources, and adoption of green technology for all activities.
    • Prohibited: Commercial mining, saw mills, industries causing pollution (air, water, soil, noise etc), the establishment of major hydroelectric projects (HEP), commercial use of wood, Tourism activities like hot-air balloons over the National Park, discharge of effluents or any solid waste or production of hazardous substances.
    • Under regulation: Felling of trees, the establishment of hotels and resorts, commercial use of natural water, erection of electrical cables, drastic change of agriculture system, e.g. adoption of heavy technology, pesticides etc, widening of roads.

    What is the recent SC judgment that has caused an uproar in Kerala?

    • On June 3, a three-judge bench of the Supreme Court heard a PIL that sought to protect forest lands in the Nilgiris in Tamil Nadu, but was later expanded to cover the entire country.
    • In its judgment, the court while referring to the 2011 guidelines as “reasonable”, directed all states to have a mandatory 1-km ESZ from the demarcated boundaries of every protected area.
    • It also stated that no new permanent structure or mining will be permitted within the ESZ.
    • If the existing ESZ goes beyond 1-km buffer zone or if any statutory instrument prescribes a higher limit, then such extended boundary shall prevail, the court, as per the Live Law report, said.

    Why are people protesting against it?

    • There is a high density of human population near the notified protected areas.
    • Farmer’s groups and political parties have been demanding that all human settlements be exempt from the ESZ ruling.
    • The total extent of the wildlife sanctuaries in Kerala is eight lakh acres.
    • If one-km of ESZ is demarcated from their boundaries, around 4 lakh acres of human settlements, including farmlands, would come within that purview.

  • Centre to set up Paddy Straw Pellet Units to arrest Stubble Burning

    stubble

    To prevent stubble burning, the Union Environment Ministry announced a ₹50 crore scheme on to incentivise industrialists and entrepreneurs to set up paddy straw pelletization and torrefaction plants.

    What is Stubble Burning?

    • Stubble (parali) burning is a method of removing paddy crop residues from the field to sow wheat from the last week of September to November.
    • It is usually required in areas that use the combined harvesting method which leaves crop residue behind.
    • This practice mostly carried out in Punjab, Haryana and UP contributes solely to the grave winter pollution in the national capital.

    Emissions from stubble burning

    • The process of burning farm residue is one of the major causes of air pollution in parts of north India, deteriorating the air quality.
    • Stubble burning is a significant source of carbon dioxide (CO2), volatile organic compounds (VOCs), nitrogen oxides (NOx) and hydrocarbons (HC).

    Despite emissions, why do farmers burn stubble?

    • Crop residue burning is practised by the farmers to prepare the land for the next cultivation.
    • The major reason behind the stubble burning is the short time available between rice harvesting and sowing of wheat as delay in sowing wheat affects the wheat crop.
    • Between the harvesting of the paddy crop and the sowing of the next crop, there is only a two to three weeks’ time window is left.
    • Even though farmers are aware that the burning of straw is harmful to health, they do not have alternatives for utilizing them effectively.
    • The farmers are ill-equipped to deal with waste because they cannot afford the new technology that is available to handle the waste material.
    • Therefore, stubble burning is considered one of the cheapest methods to clean the field after the harvesting season.

    Impact of stubble burning

    • Air Pollution: Stubble burning emits toxic pollutants in the atmosphere containing harmful gases like Carbon Monoxide (CO), methane (CH4), carcinogenic polycyclic aromatic hydrocarbons, volatile organic compounds (VOC). These pollutants disperse in the surroundings and eventually affect air quality and people’s health by forming a thick blanket of smog. Along with vehicular emissions, it affects the Air Quality Index (AQI) in the national capital and NCR.
    • Soil degradation: Soil becomes less fertile and its nutrients are destroyed when the husk is burned on the ground. Organic content of soil is completely destroyed. Stubble burning generates heat that penetrates into the soil, causing an increase in erosion, loss of useful microbes and moisture.

    Alternative solutions

    • Power generation: The available paddy straw can be effectively used for power generation, which will go a long way towards overcoming the problem of disposal of crop residues and power deficit in the region.
    • In-situ decomposition: Suitable machinery for collection, chopping and in situ incorporation of straw is required. We can use Pusa Biodecomposer, Biomethanation etc.
    • Organic manuring: Convert the removed residues into enriched organic manure through composting.

    Conclusion

    • Unless financial assistance is to be provided by the Centre for boosting farm mechanization, it is difficult to completely stop stubble burning.
    • States need to make alternative arrangements for the consumption of paddy straw into the soil as per the directions of the NGT.

  • Species in news: Sloth Bear

    sloth bear

    The first World Sloth Bear Day was observed yesterday to generate awareness and strengthen conservation efforts around the unique bear species endemic to the Indian subcontinent.

    Sloth Bear

    • The sloth bear (Melursus ursinus) is an important species and endemic to the Indian subcontinent with small populations in Nepal and Sri Lanka.
    • Classified as “vulnerable” on the IUCN Red List, sloth bears are endemic to the Indian sub-continent and 90% of the species population is found in India.
    • Listed under Schedule I of the (Wildlife Protection) Act of India, 1972, the species has the same level of protection as tigers, rhinos and elephants.
    • Commercial international trade of the sloth bear (including parts and derivatives) is prohibited as it is listed in Appendix I of the Convention on International Trade in Endangered Species (CITES).
    • The sloth bears are omnivorous and survived on termites, ants and fruits.

    Why protect sloth bears?

    • For a long time, sloth bears were exploited as dancing bears. Though the practice has been banned there are still a few cases of rescue.
    • Sloth bears are one of the most aggressive extant due to large human populations often closely surrounding reserves that hold bears.
    • Aggressive encounters and attacks are relatively frequent, though in some places, attacks appear to be a reaction to encountering people accidentally.

  • Urban Challenge, Problems and Solutions

    Context

    • After flooding of major metropolitan cities of Bengaluru, Gurgaon and Delhi following heavy rainfall, the Centre has pointed to two cities – Davanagere and Agartala – as successful examples of cities that have curbed urban flooding.

    Why cities are  so important in India?

    • Drivers of Growth: Urbanisation has played and will continue to play a critical role in India’s growth story in the 21st century.
    • Cities are seen as GDP multipliers: By some estimates, Indian cities already contribute up to 70% of the country’s GDP. Yet, depending on which official estimates you use, India is just 26% or 31% urban. But there is growing evidence that India is more urban than is officially recognized.
    • Cities have more productivity: Well-functioning and diverse cities allow for the sharing and cross-pollination of ideas, which in turn drive greater productivity.

    Urban

    What are the Urban challenges?

    • Lack of Planning: current urban planning policies and practice have led to suboptimal use of land in Indian cities. This has multiple consequences. There is not enough floor space for accommodating migrants in search of economic opportunities; they make space for themselves in informal settlements. There is also not enough land in the public domain for developing adequate open spaces or augmenting infrastructure capacities.
    • Lack of Housing:The pandemic revealed that the cities’ economies rely on migrant populations in the formal and informal sectors. Workers in both markets move from rural to urban and urban to urban areas as they find better opportunities; they are mobile and need adequate rental options. Today, in most Indian cities, this demand is not met and leads to unaffordable options, pushing the poorer sections out to slums and other informal settlements.
    • Lack of Transport: Indian cities are infamous for their road congestion; three of them rank in the 10 most congested in the world according to the 2020 TomTom Travel Index with Mumbai ranking second. The existing public transportation systems are already overcrowded and of poor quality.
    • Lack of Public health: Like other health crises, the COVID-19 pandemic revealed the need to ensure adequate healthcare services and sanitation infrastructure for a healthy population in cities. In the initial months of the outbreak, the focus of health services shifted entirely towards addressing the novel coronavirus, leaving other health issues unaddressed and shutting down routine care services.
    • Impact on Environment: The causes for low air quality are multiple; vehicular movement and on-road congestion are major contributors. A safe and clean environment is key to good public health.
    • Problems faced by vulnerable sections: The economic shock and work from home guidelines changed migration patterns; workers in cities returned to their home towns and villages. Slum dwellers, with limited access to adequate infrastructure, and migrant workers, disenfranchised from social protection systems or daily wagers, were more vulnerable to this shock. In the medium and long term, it is difficult to predict what the job market will be in cities.

    Urban

    What can be done to address the urban challenges?

    • Future planning is necessary: Manage the spatial growth of cities and allow them to build more planned road networks for future horizontal expansion and revoke faulty policies that constrain the use of floor space to build vertically.
    • Housing for all scheme is important: Focus on providing public housing for the poor; India can learn from successful models in Singapore or Hong Kong and understand the strategic challenges of other international examples such as Mexico. India can also work toenable efficient rental markets
    • Holistic transport should be focused: Integrate formal and informal modes of transportation into holistic transportation strategies to ensure seamless mobility, as well as first and last mile connectivity.
    • Increasing funds to Cities: Decentralise fiscal powers to the local level and train city authorities so that they can make more strategic decisions in health expenditures or public health infrastructure, as well as gain the capacity to raise their own resources.
    • Need of a healthy Environment: Increase the number of open spaces in the public domain, maintain them and monitor their use. Prepare for disasters with robust framework of physical infrastructures, road networks and large open spaces. Build adequate infrastructure to support the sustainable development of emerging Tier-2 and Tier 3 towns.
    • More attention to vulnerable: Develop more systematic identification mechanisms of the urban poor to ameliorate the delivery of public services and social protection. Collect accurate data on migrant population and capture their socio-economic diversity to better address their needs. Monitor access to services, housing and jobs of the vulnerable communities in real time.

    Urban

    Conclusion

    • Urban infrastructure is crumbling day by day. In the next 25 years, cities will have more population than rural areas. Indian cities need urgent reform in order to unlock their economic potential and transform quality of life.

    Mains Question

    Q.Discuss the urban infrastructure challenges? What are the governments scheme and actions to address the urbanization challenges?

  • Stubble burning in Punjab at 3-year low

    stubble

    Though early days, the number of crop fires reported out of Punjab are at a three-year low, suggest data from the Indian Agricultural Research Institute (IARI) that tracks such fires via satellite.

  • Food security and Climate change:The Interlink

    Food securityContext

    • In pursuance of the earlier announcement of additional food security under PMGKAY, the Union Cabinet has approved the extension for the Pradhan Mantri Garib Kalyan Anna Yojana (PMGKAY-Phase VII) for a further period of 3 months from October to December 2022.

    What is Climate Change?

    • United Nations defines Climate change as long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil and gas

    What is food security?

    • The Food and Agriculture Organization (FAO)defines food security as , when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life.

    Food securityPradhan Mantri Garib Kalyan Anna Yojana?

    • Pradhan Mantri Garib Kalyan Anna Yojana (PM-GKAY) is a scheme as part of Atmanirbhar Bharat to supply free food grains to migrants and poor.
    • Phase-I and Phase-II of this scheme was operational from April to June, 2020 and July to November, 2020 respectively.
    • The PMGKAY scheme for Phase VI from April-September, 2022 would entail an estimated additional food subsidy of Rs. Rs. 80,000 Crore.

    How food security and climate change are interlinked?

    • Extreme events: India is going to have extreme events such as heatwaves, droughts, floods, etc of increasing intensity and frequency.
    • Rising GHGs emission: We may keep blaming developed economies and ask for climate justice, yet we will have to act fast and boldly to correct our own policies that increase GHG emissions and aggravate the situation.
    • Subsidies: Power provided at next-to-nothing prices, free water and highly subsidised fertilisers especially urea are some of the policies that are damaging the natural environment.
    • Food ecosystem: Food security is one of the leading concerns associated with climate change. Climate change affects food security in complex ways. It impacts crops, livestock, forestry, fisheries and aquaculture, and can cause grave social and economic consequences in the form of reduced incomes, eroded livelihoods, trade disruption and adverse health impacts.

    Food securityWhy food security is a matter of concern?

    • Fiscal deficit: The fiscal deficit of the Centre may go higher than provisioned in the Budget for FY23. The finance ministry not supporting the extension of this free food beyond September was, economically, a rational recommendation. More so as Covid-19 is behind us and the economy is back to its normal level of activity.
    • Depleting stocks: The PMGKAY was announced in April 2020 in the wake of the pandemic’s first wave. At that time, it was perhaps necessary to support all those who lost their jobs. But doubling free rations depleted the bulging stocks of grains. Now with wheat procurement having plummeted, there is a concern about whether stocks are enough to curb inflationary expectations in the country.
    • Less harvest: To replenish wheat stocks in FCI godowns, the government will have to raise the minimum support price (MSP) of wheat quite substantially. For rice, the current stocks are ample, but given the monsoon vagaries, the forthcoming rice harvest is estimated to be about 7 million tonnes less.
    • Rising MSP: PMGKAY will be difficult to extend beyond December without putting an undue burden on MSPs and the fiscal deficit.
    • Other reasons:
    1. Inflation: Even though the RBI has raised the repo rate by 50 basis points, the probability of inflation, as measured by the consumer price index (CPI), remaining higher than the central bank’s tolerance band is increasing by the day.
    2. Depreciating Rupee: The RBI has already spent more than $80 billion to support the rupee, and there are limits to which it can go. And, if RBI tries to hold the rupee artificially high, it will adversely hit Indian exports, widening the current account deficit and putting further pressure on the rupee. The best that RBI can and should do is to avoid a sudden and abrupt fall in the rupee, but also let it find its natural level given what is happening globally, especially in the currency markets.
    3. Long haul: The risks of higher inflation from the falling rupee remain and are likely to continue for at least one year, if not more.

    Food securityWhat can we do?

    • Increasing foreign exchange reserves: Government have to have innovative policies to promote exports and attract more foreign direct investment (FDI).
    • Fixing Issue price: fix the issue prices of PDS supplies at half the MSP and limit the PDS coverage to 30 per cent of the bottom population.
    • On rupee fall: The best that RBI can and should do is to avoid a sudden and abrupt fall in the rupee, but also let it find its natural level given what is happening globally, especially in the currency markets.
    • Use of technology: If we have to tame food inflation, we will have to invest more in climate-smart agriculture, in precision farming, with high productivity and less damage to natural resources.
    • Right ecosystem: Science and technologies can, of course, help us, but they cannot be scaled in a perverse policy ecosystem.
    • Adoption of sustainable agricultural practices: India needs to step up public investment in development and dissemination of crop varieties which are more tolerant of temperature and precipitation fluctuations and are more water and nutrient efficient.
    • Management of water resources: A four pronged strategy is recommended for the water sector; Increase irrigation efficiency, Promote micro irrigation in water-deficient areas, Better water resource infrastructure planning, Restoration of water bodies in rural areas, Stronger emphasis on public health.
    • Long-term relief measures in the event of natural disasters: A recent report by NITI Aayog suggests that the government should transfer a minimum specified sum of cash to affected farmers and landless workers as an instant relief. For richer farmers who may want insurance above this relief, the report recommends a separate commercially viable crop insurance programme.

    Conclusion

    • So far India has done well to tame the food inflation as compared to other developed and developing economies. Present policy of RBI burning the FOREX and government increasing the deficit is unsustainable in long run. Food security needs to be insured by climate resilient policies for long term sustenance.

  • Nord Stream Pipeline Leakage: A climate Catastrophe

    Nord StreamContext

    • Four leakages were reported at different points in the Nord Stream pipelines, linking Russia and Europe, since September 26. Two of the leaks were in Swedish waters while the other two were reported from Danish waters. The European Union said they suspected “sabotage” behind the leaks.

    What is Nord Stream Pipeline?

    • Nord Stream 1:
    • Nord Stream 1 is the biggest pipeline transporting natural gas between Russia and Europe via Germany.It is a system of offshore natural gas pipelines running under the Baltic Sea from Russia to Germany.
    • Nord Stream 1 is a 1,224 km underwater gas pipeline that runs from Vyborg in northwest Russia to Lubmin in northeastern Germany via the Baltic Sea.
    • Nord Stream 2:
    • Russian threats to choke this gas supply to Europe present an economic threat to Germany.
    • To expand options and double the supply from Russia, Germany decided to build Nord Stream 2.
    • The construction of the $11 billion-worth Nord Stream 2 was completed in 2021 but never began commercial operations.

    Nord StreamWhy the Nord Stream pipeline is so important?

    • For Germany: Energy prices in Germany, Europe’s largest economy, are among the lowest in the continent because of the cheap gas supplies via Nord Stream 1. This also makes German manufactured goods more competitive in the international market.
    • For European Union: In 2021, Russia supplied nearly 40 per cent of the EU’s natural gas needs through this pipeline. The flows through Nord Stream play a vital role in filling up the national storage tanks of EU. It is crucial to provide the required heating in the upcoming winter.
    • For Russia: Russia is using the supplies via the crucial pipeline as a bargain to navigate its economy through sanctions from the western countries.

    What is the current status of Nord Stream Pipeline?

    • Nord stream pipeline is the largest single supply route for Russian gas to Europe. The Russian state owned gas company Gazprom has a majority ownership in the pipeline.
    • While it was running at just 20% of its capacity since the Russia-Ukraine conflict began, the company, in early September fully cut gas flows from the pipeline on the pretext of maintenance.
    • According to Bloomberg, while 40% of Europe’s pipeline gas came from Russia before Russia Ukraine the war, the number now stands at just 9%.
    • Even though both pipelines were not running commercially, they had millions of cubic metres of gas stored in them.

    The recent leakage in the pipeline

    • Commercial Methane: Measuring satellite firm GHGSat says, that a conservative estimate based on available data suggested that the leaks together were releasing ‘more than500 metric tonnes of methane per hour’ when first breached, with the flow decreasing over time.
    • Biggest methane leakage ever: According to UNEP The leakage from the Nord Stream natural gas pipeline system under the Baltic Sea have led to perhaps the single biggest release of methane ever recorded.
    • Amount of leakage: The rate of leakage at one of the four points of rupture in the pipeline was 22,920 kg per hour. That is equal to burning about 286,000 kg of coal every hour, according to scientists.

    Nord StreamWhat will be the Impact of methane leakage?

    • Possibility of more leakage: With the timeframe for repairs being uncertain, the pipelines were unlikely to provide any gas to Europe in the forthcoming winter months, even if the political will to resume supply was found.
    • Commercial damage: European gas prices spiked after reports of the leaks emerged; European Benchmark prices rose 12% on Tuesday, while Dutch and British Prices continued to rise.
    • Ozone formation: Methane is the primary contributor to the formation of ground-level ozone, a hazardous air pollutant and greenhouse gas, exposure to which causes 1 million premature deaths every year.
    • Green House gas: Methane is also a powerful greenhouse gas. Over a 20-year period, it is 80 times more potent at warming than carbon dioxide.
    • Global warming: Methane has accounted for roughly 30 per cent of global warming since pre-industrial times and is proliferating faster than at any other time since record keeping began in the 1980s.
    • Emission have already increased during the lockdown: According to data from the United States National Oceanic and Atmospheric Administration, even as carbon dioxide emissions decelerated during the pandemic-related lockdowns of 2020, atmospheric methane shot up.

    Why is it important to reduce methane emission?

    • Short lifespan: Carbon dioxide remains in the atmosphere for hundreds to thousands of years. But it takes only about a decade for methane to break down. So, reducing methane emissions now would have an impact in the near term and is critical for helping keep the world on a path to 1.5°C.
    • Human caused methane emissions: Human-caused methane emissions could be reduced by as much as 45 per cent within the decade. This would avert nearly 0.3°C of global warming by 2045, helping to limit global temperature rise to 1.5˚C and putting the planet on track to achieve the Paris Agreement targets.
    • Prevent premature deaths: Every year, the subsequent reduction in ground-level ozone would also prevent 260,000 premature deaths, 775,000 asthma-related hospital visits, 73 billion hours of lost labour from extreme heat and 25 million tonnes of crop losses.
    • Reducing the Agriculture emission: Agriculture and allied activities remains the biggest contributor of methane emission. The UN’s Koronivia Joint Work on Agriculture initiative is supporting the transformation of agricultural and food systems, focusing on how to maintain productivity amid a changing climate. Representatives are also working to mainstream agriculture into the UN Framework Convention on Climate Change.

    Conclusion

    • Nord stream pipeline leakages will further exacerbate the ozone formation, Green House Gas emissions global warming and thereby climate change. In the spirit of Paris climate change agreement nations must act together to rein in the menace of GHG emissions.
