  • Species in news: Physella Acuta

    A tiny snail with a striking, pellucid golden-yellow shell found in the Edappally canal in Kochi has been flagged as an invasive species that could play havoc with native ecosystems.

    Snail Physella Acuta

    • First described by J.P.R. Draparnaud in 1805, Physella acuta is considered native to North America but is now found in all continents except Antarctica.
    • The snail was first reported in India in the early 1990s.
    • It is believed to have reached Kerala through the aquarium trade, a major vector for invasive species.
    • In Kerala, the snail had made its home in a highly polluted reach plagued by high sedimentation, untreated sewage, commercial effluents, construction wastes and a thick growth of invasive aquatic weeds.

    Threats posed

    • This snail plays host to worms that can cause food-borne diseases and skin itches in humans.
    • Moreover, its rapid growth rate, air-breathing capability, and tolerance to pollution make it a potential competitor to native fauna.

  • Centre and states must work together to tackle the pollution in the NCR

    Context

    Supreme Court (SC) judges have pulled up the Delhi and central governments for not doing enough to correct the dire air quality situation. They also remarked on what message we are sending to the world.

    The pollution problem raises doubt about the quality of urbanisation in India

    •  If one looks at the capitals of G20 countries, Delhi’s air quality index (AQI) during November 1-15, is by far the worst at 312, as per World Air Quality Index Project.
    •  India’s distinction goes beyond Delhi.
    • As per the World Air Quality Report of 2020, prepared by IQAir (a Swiss organisation), of the 30 most polluted cities in the world, 22 are in India.
    • The problem is much deeper, raising doubts about the quality of our urbanisation.

    Contributing sources and their share

    • Contributing sources: As per the report of the Ministry of Environment, Forest, and Climate Change submitted to the UN Framework Convention on Climate Change following sources contribute in the given proportion:
    • Energy generation (largely coal-based thermal power) is the biggest culprit with a share of 44 per cent in greenhouse gas emissions,
    • Energy generation is followed by manufacturing and construction-18 per cent.
    • Agriculture-14 per cent.
    • Transport-13 per cent industrial processes and product use- 8 per cent and waste burning- 3 per cent.

    Suggestions to tackle Delhi’s pollution

    • As per the System of Air Quality Forecasting and Research (SAFAR), the reasons for poor AQI differ day to day.
    • On a particular day, say November 7, stubble burning contributed 48 per cent of Delhi’s air pollution, which fell to just 2 per cent on November 18.
    • Reduce rice cultivation: The Centre needs to sit down with neighbouring states and come up with a plan to reduce the rice area in this belt, which is already depleting the water table, creating methane and nitrous oxide, to incentivise farmers to switch to other crops through better returns than in rice cultivation.
    • Adopt EVs: To tackle vehicular pollution, we need a massive drive towards electric vehicles (EVs), and later towards green hydrogen when it becomes competitive with fossil fuels.
    • Charging stations: Scaling up EVs quickly demands creating charging stations on a war footing.
    • Develop carbon sink: Delhi also needs a good carbon sink.
    • Rejuvenating the Ridge area with dense forests and developing thick forests on both sides of the Yamuna may help.

    Enhancing farmers income through solar farming

    •  The Prime Minister has done a commendable job in Glasgow to commit that 50 per cent of India’s energy will be from renewable sources by 2030.
    • To replace coal in energy generation, solar and wind is the way to go at the all-India level.
    • The current model in solar energy is heavily tilted towards companies.
    • They are setting up large solar farms on degraded or less fertile lands.
    • We can supplement that model by developing solar farms on farmers’ fields.
    • This would require solar panels to be fixed at a 10 feet height with due spacing to let enough sunlight come to the plants for photosynthesis.
    • These “solar trees” can then become the “third crop” for the farmers, earning them regular income throughout the year, provided the law allows them to sell this power to the national grid.
    • The Delhi government’s pilot in Ujwa KVK land on these lines showed that farmers can earn up to Rs 1 lakh per acre per year from this “solar farming”.
    • This is on top of the two crops they can keep growing under those solar trees.
    • This will double farmers’ income within a year.

    Conclusion

    As deteriorating air quality grips the whole country, we need to work on multiple levels with coordination to tackle the problem.

  • [pib] Project RE-HAB

    Buoyed by the success of its innovative Project RE-HAB (Reducing Elephant-Human Attacks using Bees) in Karnataka, Khadi and Village Industries Commission (KVIC) has now replicated the project in Assam.

    Project RE-HAB

    • Project RE-HAB is a sub-mission of KVIC’s National Honey Mission.
    • Under the project, “Bee-fences” are created by setting up bee boxes in the passageways of elephants to block their entrance to human territories.
    • The boxes are connected with a string so that when elephants attempt to pass through, a tug or pull causes the bees to swarm the elephant herds and dissuade them from progressing further.
    • It is a cost-effective way of reducing human-wild conflicts without causing any harm to the animals.

    How does it work?

    • It is scientifically recorded that elephants are annoyed by the honey bees.
    • Elephants also fear that the bee swarms can bite the sensitive inner side of the trunk and eyes.
    • The collective buzz of the bees is annoying to elephants that force them to return.

  • Species in news: Lesser Florican

    In a major discovery, the longest in-country migration route of lesser floricans, the endangered birds of the bustard group, has been tracked for the first time from Rajasthan to Maharashtra’s Ahmednagar district.

    Lesser Florican

    • The lesser florican (Sypheotides indicus), also known as the likh or kharmore, is the smallest in the bustard family.
    • It is endemic to the Indian Subcontinent where it is found in tall grasslands and is best known for the leaping breeding displays made by the males during the monsoon season.
    • The male has a contrasting black and white breeding plumage and distinctive elongated head feathers that extend behind the neck.
    • These bustards are found mainly in northwestern and central India during the summer but are found more widely distributed across India in winter.
    • The only similar species is the Bengal florican (Houbarobsis bengalensis) which is larger and lacks the white throat, collar and elongated plumes.

    Conservation status

  • Perform, Achieve and Trade (PAT) Scheme

    A recent report by the Centre for Science and Environment (CSE) has attributed the inefficiency of the PAT scheme to non-transparency, loose targets and overlooked deadlines.

    PAT Scheme

    • Perform Achieve and Trade (PAT) scheme is a flagship program of Bureau of Energy Efficiency under the National Mission for Enhanced Energy Efficiency (NMEEE).
    • NMEEE is one of the eight national missions under the National Action Plan on Climate Change (NAPCC) launched by the Government of India in the year 2008

    Working of the scheme

    • PAT is a market-based compliance mechanism to accelerate improvements in energy efficiency in energy-intensive industries.
    • The energy savings achieved by notified industries is converted into tradable instruments called Energy Saving Certificates (ESCerts).
    • The ESCerts after issuance by the Bureau of Energy Efficiency are traded at Power Exchanges.

    What is PAT cycle?

    • The government shortlists industries and restricts the amount of energy they can consume and defines a time limit of three years by when this restriction should be met as part of PAT.
    • These three years of time are called one PAT cycle.
    • The industries are chosen after in-depth, sector-wise analysis by the government.
    • Industries that participate in this scheme are called designated consumers (DC).
    • Those that overachieve their targets are issued energy savings certificates (ESCerts) that can be traded with industries that have not achieved their targets.
    • Non-achievers have to buy the ESCerts after the three years for compliance.

    Various PAT cycles

    • PAT covered about 13 energy-intensive sectors
    • Sectors included are thermal power plants (TPP), cement, aluminium, iron and steel, pulp and paper, fertilizer, chlor-alkali, petroleum refineries, petrochemicals, distribution companies, railways, textile and commercial buildings (hotels and airports)
    • Announcements for six cycles since 2012 have been made so far

  • Emission caused by Nuclear Energy

    Supporters of the Nuclear Energy source say that it is a climate-friendly way to generate electricity. However, this is subjected to various considerations often not discussed.

    Why focus on Nuclear Energy?

    • The main factors for its choice were reliability and security of supply.
    • The latest figures on global carbon dioxide emissions call into question the world’s efforts to tackle the climate crisis.

    Soaring CO2 emissions

    • CO2 emissions are set to soar 4.9% in 2021, compared with the previous year, according to a study published earlier this month by the Global Carbon Project (GCP), a group of scientists that track emissions.
    • In 2020, emissions dropped 5.4% due to the COVID-19 pandemic and associated lockdowns.
    • The energy sector continues to be the largest emitter of greenhouse gases, with a share of 40% — and rising.

    Is nuclear power a zero-emissions energy source?

    No. Nuclear energy is also responsible for greenhouse gas emissions.

    • Uranium mining: Uranium extraction, transport and processing produces emissions.
    • Construction of power plants: The long and complex construction process of nuclear power plants also releases CO2, as does the demolition of decommissioned sites.
    • Nuclear waste and its transportation: This also has to be transported and stored under strict conditions — here, too, emissions must be taken into account.
    • Water consumption: Power plants depend on nearby water sources to cool their reactors, and with many rivers drying up, those sources of water are no longer guaranteed.

    How much CO2 does nuclear power produce?

    • Results vary significantly, depending on whether we only consider the process of electricity generation, or take into account the entire life cycle of a nuclear power plant.
    • A report released in 2014 by the IPCC estimated a range of 3.7 to 110 grams of CO2 equivalent per kilowatt-hour (kWh).
    • It’s long been assumed that nuclear plants generate an average of 66 grams of CO2/kWh.

    How climate-friendly is nuclear compared to other energies?

    • If the entire life cycle, nuclear energy certainly comes out ahead of fossil fuels like coal or natural gas.
    • But the picture is drastically different when compared with renewable energy.
    • Nuclear power releases 3.5 times more CO2 per kilowatt-hour than photovoltaic solar panel systems.
    • Compared with onshore wind power, that figure jumps to 13 times more CO2.
    • When up against electricity from hydropower installations, nuclear generates 29 times more carbon.

    Can we rely on nuclear energy to help stop global warming?

    • Around the world, nuclear energy representatives, as well as some politicians, have called for the expansion of atomic power.
    • Other countries have also supported plans to build new nuclear plants, arguing that the energy sector will be even more damaging for the climate without it.

    Feasibility of Nuclear Energy

    • High cost of construction: Due to the high costs associated with nuclear energy, it also blocks important financial resources that could instead be used to develop renewable energy.
    • Renewables are better: Those renewables would provide more energy that is both faster and cheaper than nuclear.
    • High water consumption: During the world’s increasingly hot summers, several nuclear power plants have already had to be temporarily shut down due to water scarcity.

    Conclusion

    • Taking into account the current overall energy system, nuclear energy is by no means CO2 neutral.
    • The contribution of nuclear energy is viewed too optimistically.
    • In reality construction, times are too long and the costs too high to have a noticeable effect on climate change. It takes too long for nuclear energy to become available.

  • Africa’s Great Green Wall (GGW) Program

    Africa’s Great Green Wall (GGW) program to combat desertification in the Sahel region is an important contribution towards combating climate change, Food and Agriculture Organization (FAO) said in a study.

    Note the countries swept by the GGW project on the African map.

    About GGW Program

    • The Great Green Wall project is conceived by 11 countries located along the southern border of the Sahara and their international partners, is aimed at limiting the desertification of the Sahel zone.
    • Led by the African Union, the initiative aims to transform the lives of millions of people by creating a mosaic of green and productive landscapes across North Africa.
    • The initial idea of the GGW was to develop a line of trees from east to the west bordering the Saharan Desert.
    • Its vision has evolved into that of a mosaic of interventions addressing the challenges facing the people in the Sahel and the Sahara.

    Why was such project incepted?

    • The project is a response to the combined effect of natural resources degradation and drought in rural areas.
    • It aimed to restore 100 million hectares of degraded land by 2030; only four million hectares had been restored between 2007 and 2019.
    • It is a partnership that supports communities working towards sustainable management and use of forests, rangelands and other natural resources.
    • It seeks to help communities mitigate and adapt to climate change, as well as improve food security.

  • India, while moving to renewable energy needs to focus on sustainable well-being

    Context

    With current per capita emissions that are less than half the global average, India’s pledge to reach ‘net zero’ emissions by 2070 has cemented India’s credentials as a global leader.

    Implication of net-zero by 2070

    • The political implication of the date 2070 is that the world should get to ‘net-zero’ by 2050.
    • For that, the rich countries will need to do more and step up closer to their share of the carbon budget.
    • India’s stand also signals that it will not act under external pressure, as requiring equal treatment is the hallmark of a global power, and will have an impact on other issues.

    How focus on coal harms developing countries

    • The subject of oil was not touched at COP26, even as automobile emissions are the fastest growing emissions, because it is a defining feature of western civilisation.
    • Most abundant source of energy: Coal is the most abundant energy source, essential for base load in electrification, and the production of steel and cement.
    • Its use declines after the saturation level of infrastructure is reached.
    • Declining role of G-7 in rule setting: That India and China working together forced the G7 to make a retraction has signalled the coming of a world order in which the G7 no longer sets the rules.
    • Specific language on finance and adaptation: After 40 years there is more specific language on both finance and adaptation finally recognising that costs and near-term effects of climate change will hit the poorest countries hardest.

    Feasibility of the goal of ‘net-zero’ by 2070

    • Seeing the challenge in terms of the scale and the speed of the transformation of the energy system assumes that India will follow the pathway of western civilisation.
    • Transition to electrification: India is urbanising as it is industrialising, moving directly to electrification, renewable energy and electric vehicles, and a digital economy instead of a focus on the internal combustion engine.
    • Most of the infrastructure required has still to be built and automobiles are yet to be bought.
    • Investment vs. incurring cost: India will not be replacing current systems and will be making investments, not incurring costs.

    Challenge for the West

    • The consumption of affluent households both determines and accelerates an increase of emissions of carbon dioxide.
    • This is followed by socio-economic factors such as mobility and dwelling size.
    • In the West, these drivers have overridden the beneficial effects of changes in technology reflected in the material footprint and related greenhouse-gas emissions.
    • The West has yet to come out with a clear strategy of how it will remain within the broad contours of its carbon budget.
    • And increasing inequality and a rise of protectionism and trade barriers imposing new standards need to be anticipated.
    • This knowledge is essential for national policy as well as the next round of climate negotiations.

    Way forward for India

    • Climate change has to be addressed by the West by reducing consumption, not just greening it.
    • Shifting the consumption pattern: Consumption patterns need to be ‘shifted away from resource and carbon-intensive goods and services, e.g. mobility from cars and aircraft to buses and trains.
    • Reducing the carbon intensity: Along with’ reducing demand, resource and carbon intensity of consumption has to decrease, e.g. expanding renewable energy, electrifying cars and public transport and increasing energy and material efficiency’.
    • Equal distribution of wealth and affordable energy use: Equally important, will be achieving a’ more equal distribution of wealth with a minimum level of prosperity and affordable energy use for all’, e.g., housing and doing away with biomass for cooking.
    • Focused research group: The Government now needs to set up focused research groups for the conceptual frame of sustainable well-being.
    • It should analyse the drivers of affluent overconsumption and circulate synthesis of the literature identifying reforms of the economic systems as well as studies that show how much energy we really need for a decent level of well-being.

    Role for legislature

    • Fundamental duty: After the Stockholm Declaration on the Global Environment, the Constitution was amended in 1976 to include Protection and Improvement of Environment as a fundamental duty.
    • Use of provision under Article 253: Parliament used Article 253 to enact the Environment Protection Act to implement the decisions reached at the Stockholm Conference.
    • Enabling new set of legislation: The decisions at COP26 enable a new set of legislation around ecological limits, energy and land use, including the efficient distribution and use of electricity, urban design and a statistical system providing inputs for sustainable well-being.

    Consider the question “Examine the feasibility of India’s ‘net-zero’ target by 2070, also suggest the way forward for India to achieve the target by focusing on sustainable well being”

    Conclusion

    For India, in parallel with the infrastructure and clean technology thrust, the focus on a decent living standard leads to behavioural change in the end-use service, such as mobility, shelter and nutrition — for change modifying wasteful trends.

  • Places in news: Majuli River Island

    Soil erosion, coupled with changing climatic conditions, has been writing a cruel destiny for the inhabitants of Majuli in Assam, the largest river island in the world.

    About Majuli Island

    • Majuli is a riverine island in the Brahmaputra River, Assam and in 2016 it became the first island to be made a district in India.
    • Majuli has shrunk as the river surrounding it has grown.
    • It had an area of 880 square kilometers (340 sq mi) at the beginning of the 20th century but having lost significantly to erosion it covers 553 square kilometers as at 2014.
    • It is the abode of the Assamese neo-Vaishnavite culture.

    Its formation

    • The island is formed by the Brahmaputra River in the south and the Kherkutia Xuti, an anabranch of the Brahmaputra, joined by the Subansiri River in the north.
    • It was formed due to course changes by the river Brahmaputra and its tributaries, mainly the Lohit.

  • The heavy lifting on climate action must begin

    Context

    Glasgow’s success was that it finished building the scaffolding for climate action initiated through the Paris Agreement. But true success depends on whether countries are receptive to these nudges.

    What were the Glasgow climate meeting’s (COP26) successes and failures?

    • Strengthened Paris Agreement mechanism: Glasgow strengthened the Paris Agreement mechanism of eliciting pledges from countries and ratcheting them up over time.
    • It requested countries to update and strengthen 2030 emission targets in their NDCs by the end of 2022, earlier than previously expected.
    • Success at Glasgow was explicitly defined around ‘keeping 1.5 degrees alive’ through such pledges.
    • There are two problems with this interpretation.
    • First, the Paris, and Glasgow, approach focusing on target-setting gives insufficient importance to the challenge of implementing those targets.
    • A focus on shorter term targets and their implementation — which India to its credit has been highlighting — will be important.
    • Second, by calling on countries to strengthen targets to align with the Paris Agreement objectives without explicitly considering that countries have different roles and responsibilities in doing so risks side-stepping, again, the long-standing issue of climate equity.

    Phase-down clause for thermal power and implications for India

    • Phasing down coal power: A specific high profile clause calls for the ‘phase down of unabated coal power and phase out of inefficient fossil fuel subsidies’.
    • It was the Indian Minister who read out an amendment modifying ‘phase-out’ to ‘phase-down’ for coal.
    • India’s concerns: India’s real concerns included not precluding subsidies for social purposes, such as for cooking gas; querying whether from an equity point of view, all countries should be asked to limit coal use at the same time; and noting the lack of mention of oil and gas.
    • A positive for all from environmental point of view: From an environmental point of view, more explicit discussion of coal, but ideally all fossil fuels, is a positive, including for India.
    • Concerns on developmental view: From a developmental view, however, India is concerned that explicit mention of coal constrains us in our choice of fuel.
    • Way out for India: A possible way out is for India to explicitly seek global support for an accelerated transition away from coal, an approach taken by South Africa.

    Challenges and achievements at COP26

    [A] Measures for adaptations

    • Adaptation has long been neglected in global negotiations, reflecting a global power imbalance that places less weight on the concerns of vulnerable nations.
    • In this context, it was a partial win that Glasgow set up an explicit two year work programme for a ‘global goal’ on adaptation.
    • No development on agenda of loss and damage: The important complementary agenda of ‘loss and damage’ – compensating for unavoidable impacts that go beyond adaptation — received at most lip service.
    • Even though there was discussion of a specific mechanism, backed by funding, to the dismay of small, vulnerable nations, only a ‘dialogue’ was established.

    [B] Climate finance commitment issue not addressed

    • Commitment on climate finance not met: Climate finance promised to be the central issue of COP26, with considerable frustration from developing countries that the decade-long commitment of $100 billion had not been met.
    • Glasgow did no more than establish a work programme on post-2025 financing and continue tracking progress on the $100 billion.
    • The exception was a call to double adaptation finance by 2025.
    • Mobilising private finance: Former Bank of England Governor Mark Carney indicated that companies committed to net zero initiatives could marshal a scarcely believable $130 trillion, suggesting growing efforts to mobilise private finance.
    • Developing countries have long insisted that publicly funded climate finance is a right devolving from the ‘polluter pays’ principle rather than aid.

    [C] Paris rulebook

    • Completion of two elements of Paris Rulebook: There were two particularly important elements of what is called the ‘Paris Rulebook’ that were completed in Glasgow.
    • Transparency framework: First, the transparency framework was completed, which includes reporting rules and formats for emissions, progress on pledges and finance contributions.
    • Rules for carbon market: The second key was completion of agreed rules for carbon markets, the complexities of which had stymied agreement for four years.
    • Rules were put in place to limit the scope for ‘double-counting’ of credits by more than one country.

    Way forward for India

    • The real determinant of success or failure rests on national politics and popular support for climate change within countries — how countries use the scaffolding.
    • For India, these politics are complex because they revolve around simultaneously balancing concerns over whether our policy space will be limited by inequities embedded in the global mitigation efforts, and our own interests as a vulnerable country in enhancing and accelerating climate action.
    • A balanced view requires consideration of both objectives.

    Consider the question “Why climate finance continues to be a contentious issue in the negotiations over climate change? Suggest the way to balance the concerns over development with the efforts at climate action.”

    Conclusion

    The meeting hit many, but not all, of its procedural benchmarks by building scaffolding for the future. But the real determinant of success or failure rests on national politics and popular support for climate change within countries.
