  • India must commit to net zero emissions

    Context

    The United Nations Climate Change Conference (COP26) in November in Glasgow is shaping up to be the most important climate meeting since the Paris Agreement in 2015.

    What are net-zero emissions?

    Carbon neutrality refers to achieving net-zero carbon dioxide emissions. This can be done by balancing emissions of carbon dioxide with its removal or by eliminating emissions from society.

    Increase in pace and scale of climate action

    • Over 50% of the global economy is already committed to net zero emissions by 2050.
    • Over 100 countries have already committed to net zero emissions by 2050, with more expected at COP26.
    • The pace and scale of climate action are only set to increase, with the recent IPCC report unequivocal on the need for urgent and stronger responses.
    • It is not only governments that are increasing climate action. The business world is too, not just to protect themselves against the risks of climate change but also to take advantage of the massive opportunities arising as the global economy shifts to net-zero emissions.

    Why India should commit to a net-zero target

    • National interest due to vulnerability: India itself has a national interest in ambitious global and national climate action.
    • It is among the most vulnerable countries to climate change and, therefore, should be among the more active against the threats.
    • Influence as a rising power: Second, as a rising power, India naturally seeks stronger influence globally.
    • Being an outlier on the global challenge facing our generation does not support this aim.
    • Drag on international diplomacy: India’s reluctance to commit to net-zero will become a significant drag on India’s international diplomacy.
    • This applies not just to key relationships like with the U.S., but also with much of the Group of 77 (G77) states, who are increasingly concerned to see climate action, and in multilateral groupings such as the United Nations and ASEAN-APEC.
    • Interconnected with the economy: There is no longer a trade-off between reducing emissions and economic growth.
    • For example, the U.K. has reduced emissions by over 40% and grown its economy by over 70% since 1990.
    • Solar energy costs have fallen 90% in recent years, providing the cheapest electricity in India ever seen.
    • Also, given the negative impacts, addressing climate change in India’s economic development is now central to success, not an added luxury to consider.
    • The transition of the global economy to net zero emissions is the biggest commercial opportunity in history.
    • In just the energy sector alone, an estimated $1.6 to $3.8 trillion of investment is required every year until 2050.

    India’s climate actions

    • India is set to significantly exceed its Paris Agreement commitment of reducing the emissions intensity of its GDP by 33-35% below 2005 levels by 2030.
    • Emphasis on renewable: India is impressing the world with its leading roll-out of renewable energy and target for 450GW by 2030, linked to its leadership on the International Solar Alliance and recent national hydrogen strategy.
    • Corporates: Indian corporates are also stepping up, with the Tata Group winning awards on sustainability, Mahindra committing to net-zero by 2040, and Reliance by 2035.
    • Notwithstanding reasonable arguments about historical responsibility, per capita emissions, and equity, India’s national interests in climate action are now engaged in ways that go significantly beyond waiting for donor support to drive ambition.

    The way forward: International cooperation

    • The world needs to work together for success in the form of stronger political engagement, policy support in areas of mutual challenge such as energy policy, carbon markets, and economic recovery.
    • Practical support and cooperation in areas like renewable energy and integrating it with the national grid, zero-emissions transport, decarbonising hard to abate sectors like steel, cement, and chemicals, and decarbonising agriculture offer significant scope to raise ambition.
    • As does working with India on innovative green financing for decarbonizing investment.

    Conclusion

    India’s tryst with destiny rests in its own remarkable hands, as it always has been. In a land where the earth is called mother, and Mahatma Gandhi, major religions, and the Constitution enshrine environmental care, commitment to net zero emissions by 2050 should almost be foretold.

  • Ladakh adopts State Animal and Bird

    Ladakh has adopted two endangered species, snow leopard and black-necked crane, as State animal and State bird, two years after it was carved out as a separate Union Territory (UT) from the erstwhile State of J&K.

    Snow Leopard

    • The snow leopard (Panther unica) and black-necked crane (Grus nicricollis).
    • Snow leopard, whose numbers are dwindling worldwide, has been categorized as “vulnerable” in the International Union for Conservation of Nature Red List.
    • In total, there are about 7,500 snow leopards left in the world, out of which 500 are in India.
    • However, experts state that the population of snow leopards is between 200-300 in Ladakh alone.

    Black-necked Crane

    • The black-necked crane is found in eastern Ladakh’s high-altitude wetlands and marshes.
    • It is mostly listed as Near Threatened on the International Union for Conservation of Nature (IUCN) red list.
    • Considered loyal couples, they are only found in Ladakh’s Changthang region. They arrive in March for breeding and migrate by October end or early November.
    • It was the State bird of J&K before August 5, 2019.

    About Ladakh

    • Ladakh was established as a union territory of India on 31 October 2019, following the passage of the Jammu and Kashmir Reorganization Act.
    • Prior to that, it was part of the Jammu and Kashmir state. Ladakh is the largest and the second least populous union territory of India.
    • It extends from the Siachen Glacier in the Karakoram range to the north to the main Great Himalayas to the south.
    • The eastern end, consisting of the uninhabited Aksai Chin plains, is claimed by the Indian Government as part of Ladakh and has been under Chinese control since 1962.
    • The largest town in Ladakh is Leh, followed by Kargil, each of which headquarters is a district.
    • The Leh district contains the Indus, Shyok and Nubra river valleys. The Kargil district contains the Suru, Dras and Zanskar river valleys.

  • Managing natural resources

    Context

    A project in Meghalaya empowers communities to take informed action pertaining to their environment.

    Depletion of natural resources in Meghalaya

    • In recent years, many parts of Meghalaya have witnessed the loss of forest cover and natural resources have rapidly deteriorated.
    • The State, known to have spots designated as the ‘wettest places’ on earth, is now facing a severe water crisis.
    • Natural resource management becomes critical in this context.

    Challenges in natural resource management

    • Traditional practices on sustainable use of natural resources have been passed down from one generation to another.
    • Overexploitation: This indigenous knowledge began to slowly fade, however, owing to population growth,  the quest for unsustainable developmental activities, and indiscriminate exploitation of natural resources.
    • Inaccessibility of knowledge: Another roadblock to natural resource management was knowledge inaccessibility among rural communities.

    Providing knowledge: Landscape Management Project

    • The government wanted to see if, when provided with the correct knowledge, solutions to problems can be devised and even implemented by community members themselves.
    • The World Bank-supported Meghalaya Community-Led Landscape Management Project seeks to reactivating the community’s connection to natural resources and enabling them to tackle the resource crisis.
    • How the project worked: cross-functional teams with diverse expertise were set up.
    • The Mahatma Gandhi National Rural Employment Guarantee Scheme became the main scheme channelizing resources to impact poor households so that there was systematic convergence of all line departments such as agriculture, horticulture, soil, and water conservation.
    • The programme leverages technology and the youth population.
    • Leveraging technology, more than 2,000 village community facilitators have already been trained and are working towards climate change reversal.
    • Autonomy: To build autonomy, simple tools are used.
    • They have been designed keeping in mind many things: creating community agency, building the capacities of all persons in the programme, and ensuring frequent interactions among them.
    • Leveraging technology: Technology empowers them with real-time data, which in turn results in better programme governance, transparency, and accountability.
    • Communities are now able to articulate the complexities of their problems through a scientific lens and create their own natural resource management plans.
    • To carry forward this momentum, there is a plan to launch a Centre of Excellence in Meghalaya, a one-stop centre for natural resources management.

    Conclusion

    The project intends to empower thousands of village community facilitators and enable them to articulate the complexities of their problems through a scientific lens and create their own natural resource management plans.

  • Mumbai Climate Action Plan (MCAP)

    The Brihanmumbai Municipal Corporation (BMC) is drafting a Mumbai Climate Action Plan (MCAP) in a bid to tackle climate challenges.

    What is the Mumbai Climate Action Plan?

    • Amid warnings of climate change leading to extreme weather events in the city, the civic body has started preparing the Mumbai Climate Action Plan (MCAP).
    • It will look at climate resilience with mitigation and adaptation strategies by focusing on six areas —
    1. Sustainable waste management
    2. Urban greening and Biodiversity
    3. Urban flooding and Water Resource Management
    4. Building Energy Efficiency
    5. Air Quality and
    6. Sustainable Mobility
    • The plan is expected to be ready by November ahead of the United Nations Climate Change (COP26) conference at Glasgow, Scotland.

    Why does Mumbai need a climate action plan?

    Mumbai’s climate action plan will help set a vision and implement strategies to fight these climate challenges with mitigation and adaptation steps.

    • Flash floods: As per a study conducted by the World Resource Institute (WRI) India, the city will face two major climate challenges — the rise in temperature, and extreme rain events which will lead to flooding.
    • Temperature rise: The city has seen a constant rise in temperature after 2007, and a substantial increase in intense rainfall and storm events in the last five years.
    • Sea level rise: A recent report from the IPCC has warned that at least 12 Indian coastal cities including Mumbai will face a sea rise of 0.1 metres to 0.3 metres in the next three decades due to climate change.

    What is the greenhouse gas emission of the city?

    • The data show that Mumbai’s greenhouse gas emission was 34.3 million tonnes in 2019, and of which 24.23 million tonnes or 71 per cent came from the energy sector which is mainly based on coal.
    • At least 24 per cent or 82,21,902 tonnes is from transport, and the remaining 5 per cent or 18,53,741 tonnes from solid waste management.
    • The maximum contribution from the energy sector was mainly due to domestic and commercial usage of electricity.
    • As per the data, 95 percent of Mumbai’s electricity is coal-based and needs to be shifted to renewable energy to bring down emissions.

  • Nationally Determined Contributions

    Context

    Despite accomplishments, global pressures are intensifying on India to commit more towards the Conference of the Parties (COP26), scheduled for November 2021 in Glasgow.

    India’s accomplishments

    • At the fifth anniversary of the Paris Agreement on Climate Change (December 2020), India was the only G20 nation compliant with the agreement.
    • India has been ranked within the top 10 for two years consecutively in the Climate Change Performance Index.
    • The Unnat Jyoti by Affordable LEDs for All (UJALA) scheme is the world’s largest zero-subsidy LED bulb programme for domestic consumers.
    •  India provided leadership for setting up the International Solar Alliance, a coalition of solar-resource-rich countries, and the Coalition for Disaster Resilient Infrastructure.

    Why it is unfair to pressure India on climate action

    We can attempt to answer the question by comparing the achievements of other countries vis-à-vis India’s performance.

    • Historical perspective: World Bank data for CO2 emissions (metric tons per capita) over two decades since the Kyoto protocol informs that at the current rate, both China and the U.S. could emit five times more than India in 2030.
    • The U.K.’s emission levels could be more than 1.5 times that of India.
    • Brazil, with its dense forests, may end up at similar levels.
    • Latest efforts: Last year, China, the world’s largest GHG emitter, joined the ‘race to zero’ and targets carbon neutrality by 2060.
    • Interestingly, it hopes to peak CO2 emissions by 2030 for bending the emissions curve.
    • Recently, the U.S. rejoined the Paris Agreement and committed to reducing emissions by 50%-52% in 2030 and reaching net-zero emissions economy-wide by 2050.
    • The French government, during the novel coronavirus pandemic, set green conditions for bailing out its aviation industry.
    • However, the analysts say that no baseline for reducing emissions from domestic flights was fixed.
    • In Australia, complicated domestic politics prevented them from addressing the problem, despite the country being vulnerable, and stretches of the famous Great Barrier Reef having died in recent years.

    India’s performance

    • Exceeding the NDC commitment: India is on track (as reports/documents show) to meet and exceed the NDC commitment to achieve 40% electric power installed capacity from non-fossil fuel-based sources by 2030.
    • Reduction in emission intensity of GDP: Against the voluntary declaration for reducing the emission intensity of GDP by 20%-25% by 2020, India has reduced it by 24% between 2005-2016.
    • More importantly, we achieved these targets with around 2% out of the U.S.$100 billion committed to developing nations in Copenhagen (2009), realised by 2015.
    • Renewable energy expansion: India is implementing one of the most extensive renewable energy expansion programmes to achieve 175 GW of renewable energy capacity by 2022 and 450 GW by 2030.
    • Investment in green measures: As part of the fiscal stimulus after the pandemic, the Government announced several green measures, including:
    • a $26.5-billion investment in biogas and cleaner fuels,
    • $3.5 billion in incentives for producing efficient solar photovoltaic (PV)
    • and advanced chemistry cell battery, and $780 million towards an afforestation programme.
    •  India’s contribution to global emissions is well below its equitable share of the worldwide carbon budget by any equity criterion.

    Conclusion

    To sum up, India has indeed walked the talk. Other countries must deliver on their promises early and demonstrate tangible results ahead of COP26.

  • Leaded Petrol is officially eradicated

    The use of leaded petrol has been eradicated from the globe, a/c to the UN Environment Programme (UNEP).

    What is Leaded Petrol?

    • Tetraethyl-lead (TEL) is a petro-fuel additive, first being mixed with petrol beginning in the 1920s as a patented octane rating booster that allowed engine compression to be raised substantially.
    • This in turn caused increased vehicle performance and fuel economy.
    • The practice of adding tetraethyl lead to petrol had spread widely to all countries soon after its anti-knock and octane-boosting properties were discovered.
    • TEL is still used as an additive in some grades of aviation gasoline.

    Issues with leaded petrol

    • Lead is toxic, affects multiple body systems and is particularly harmful to young children.
    • It affects the brain, liver, kidneys, and bones. Lead is measured in the blood to understand exposure.
    • Lead in bone is released into the blood during pregnancy and becomes a source of exposure to the developing foetus.
    • More recent research has indicated that lead can damage the infant brain even at blood levels as low as 5 microunits per decilitre (μ/dl).

    India’s tryst with leaded petrol

    • India was among those countries that took early action to phase out leaded petrol. The process of phase down that had started in 1994, got completed in 2000.
    • Initially, low-leaded petrol was introduced in Delhi, Mumbai, Kolkata and Chennai in 1994, followed by unleaded petrol in 1995.
    • The entire country got low-leaded petrol in 1997 while leaded fuel was banned in the National Capital Territory of Delhi.
    • The final introduction of unleaded petrol in the entire country was mandated in April 2000.
    • This decision was also catalyzed by the Supreme Court order that had directed the introduction of unleaded petrol to enable the adoption of catalytic converters in petrol cars.

    Significance of phasing out

    • It is a milestone that will prevent more than 1.2 million premature deaths and save world economies over $2.4 trillion annually.
    • It has taken 100 years to stop the use of leaded fuel finally.

  • Hurricane Ida makes landfall in US

    Hurricane Ida has made landfall in Louisiana, US as an extremely dangerous Category 4 storm.

    What is a Hurricane?

    • A hurricane is a tropical cyclone that occurs in the Atlantic Ocean and the northeastern Pacific Ocean.
    • And a typhoon occurs in the northwestern Pacific Ocean; in the south Pacific or the Indian Ocean, comparable storms are referred to simply as “tropical cyclones” or “severe cyclonic storms”.

    What are Tropical Cyclones?

    A Tropical cyclone is an intense circular storm that originates over warm tropical oceans and is characterized by low atmospheric pressure, high winds, and heavy rain.

    • Cyclones are formed over slightly warm ocean waters. The temperature of the top layer of the sea, up to a depth of about 60 meters, need to be at least 28°C to support the formation of a cyclone.
    • This explains why the April-May and October-December periods are conducive for cyclones.
    • Then, the low level of air above the waters needs to have an ‘anticlockwise’ rotation (in the northern hemisphere; clockwise in the southern hemisphere).
    • During these periods, there is an ITCZ in the Bay of Bengal whose southern boundary experiences winds from west to east, while the northern boundary has winds flowing east to west.
    • Once formed, cyclones in this area usually move northwest. As it travels over the sea, the cyclone gathers more moist air from the warm sea which adds to its heft.

    Try this question from CSP 2020:

    Q.Consider the following statements:

    1. Jet Streams occur in the Northern Hemisphere only.
    2. Only some cyclones develop an eye.
    3. The temperature inside the eye of a cyclone is nearly 10 degree Celsius lesser than that of the surroundings.

    Which of the statements given above is/are correct?

    (a) 1 only

    (b) 2 and 3 only

    (c) 2 only

    (d) 1 and 3 only

    Destruction caused

    • Strong Winds: Cyclones are known to cause severe damage to infrastructure through high-speed winds.
    • Torrential rains and inland flooding: Torrential rainfall (more than 30 cm/hour) associated with cyclones is another major cause of damages. Unabated rain gives rise to unprecedented floods.
    • Storm Surge: A Storm surge can be defined as an abnormal rise of sea level near the coast caused by a severe tropical cyclone.

    Some (unexpected) benefits

    Although Tropical cyclones are known for the destruction they cause, when they strike they also bestow certain benefits to the climatic conditions of that area such as

    • Relieve drought conditions
    • Carry heat and energy away from the tropics and transport it towards temperate latitudes
    • Maintain a relatively stable and warm temperature worldwide

  • Places in news: Pantanal Wetlands

    Pantanal, the world’s largest tropical wetlands is facing a severe crisis due to wildfires and climate change.

    Pantanal Wetlands

    • The Pantanal is a natural region encompassing the world’s largest tropical wetland area, and the world’s largest flooded grasslands.
    • It is located mostly within the Brazilian and extends to some portions of Bolivia and Paraguay.
    • It sprawls over an area estimated at between 140,000 and 195,000 square kilometer.
    • Roughly 80% of the Pantanal floodplains are submerged during the rainy seasons, nurturing a biologically diverse collection of aquatic plants and helping to support a dense array of animal species.

    Risks faced

    • Unlike the Amazon rainforest, vegetation in the Pantanal has evolved to coexist with fire — many plant species there require the heat from fires to germinate.
    • Often caused by lightning strikes, those natural fires spring up at the end of the dry season, but the surrounding floodplains prevent them from spreading.
    • What’s different now is the drought, contributing further to the unusually dry conditions and exacerbating the fire risk.
