  • What are Western Disturbances?

    disturbance

    The days have been unusually warm for winter in New Delhi with the maximum temperature remaining above normal mostly on account of fewer western disturbances affecting this year.

    Western Disturbances

    • A western disturbance is an extratropical storm originating in the Mediterranean region that brings sudden winter rain to the northwestern parts of the Indian subcontinent.
    • They are labelled as an extra-tropical storm originating in the Mediterranean, is an area of low pressure that brings sudden showers, snow, and fog in northwest India.
    • In the term “extra-tropical storm”, storm refers to low pressure. “Extra-tropical” means outside the tropics. As the WD originates outside the tropical region, the word “extra-tropical” has been associated with them.
    • It is a non-monsoonal precipitation pattern driven by the westerlies.
    • The moisture in these storms usually originates over the Mediterranean Sea, the Caspian Sea and the Black Sea.
    • Extratropical storms are global phenomena with moisture usually carried in the upper atmosphere, unlike their tropical counterparts where the moisture is carried in the lower atmosphere.
    • In the case of the Indian subcontinent, moisture is sometimes shed as rain when the storm system encounters the Himalayas.
    • Western disturbances are more frequent and strong in the winter season.

    Impact: Winter Rainfall and Extreme Cold

    • Western disturbances, specifically the ones in winter, bring moderate to heavy rain in low-lying areas and heavy snow to mountainous areas of the Indian Subcontinent.
    • They are the cause of most winter and pre-monsoon season rainfall across northwest India.
    • An average of four to five western disturbances forms during the winter season.

    Its significance

    • Precipitation during the winter season has great importance in agriculture, particularly for the rabi crops.
    • Wheat among them is one of the most important crops, which helps to meet India’s food security.

    Try this PYQ:

    Consider the following statements:

    1. The winds which blow between 30°N and 60°S latitudes throughout the year are known as westerlies.
    2. The moist air masses that cause winter rains in the North-Western region of India are part of westerlies.

    Which of the statements given above is/are correct?

    (a) Only 1

    (b) Only 2

    (c) Both 1 and 2

    (d) Neither 1 nor 2

  • ‘Loss and Damages’ Fund Launched at the onset of COP28

    loss and damage

    On the first day of the COP28 climate conference in Dubai, a fund dedicated to assisting vulnerable nations in dealing with the effects of climate change was formally inaugurated.

    Loss and Damage: The climate change context

    • Climate change causes costly damage, including from climate-related natural disasters, such as tropical cyclones, and more gradual changes, such as desertification and rising sea levels.
    • Currently, because climate change is caused by greenhouse gases already in the atmosphere, rich industrialised countries are responsible for most of the emissions causing these phenomena.

     ‘Loss and Damages’ Fund: Inception of the idea

    • The idea of a “loss and damage” fund (LDF) was first floated in 1991.
    • Vanuatu, a low-lying island nation in the Pacific, suggested the creation of an insurance scheme, under the auspices of the UN, to help pay for the consequences of rising sea levels.
    • For thirty years such demands were left ignored at the UN.
    • But twelve months ago in Scotland, that country’s first minister promised £2m ($2.4m) to the cause.

    Why need LDF?

    • Poor countries often feel the effects first being the most vulnerable and incapable of self-mitigation.
    • They also include not only economic damage to property but also loss of livelihoods, and the destruction of biodiversity and sites that have cultural importance.
    • This broadens the scope for affected nations to claim compensation.
    • Hence loss and damage is sometimes called the “third pillar” of climate politicking, after mitigation (tackling the root cause of the problem by reducing emissions) and adaptation (preparing for current and future impacts).

    Immediate triggers for such action

    Ans. Pakistan Floods

    • Unusually heavy monsoon rains caused more than $30bn of damage and financial losses in Pakistan, equivalent to nearly 9% of the country’s GDP.
    • Natural climatic variations, notably an ocean-cooling phenomenon known as “La Niña,” were partly responsible.
    • But the rains were also made heavier by the effects of greenhouse gases.

    When will LDF be operational?

    • Further decisions have been left to a “transitional committee” that will make recommendations to enable the actual adoption of the fund at the next year COP to be held in UAE.

    Realistic picture of LDF

    • Some critical questions remain unaddressed –
    1. Who will manage this fund?
    2. Whether contributions are expected from large developing countries?
    3. What the fair share of contributors will be?

    Status of global consensus over LDF

    • During COP27, financial pledges for LDF came from multiple countries, including Austria, Belgium, Canada, France, Germany, and New Zealand, joining Denmark and Scotland, which had made pledges previously.

    How much fund is necessary?

    • The expected monetary compensation from the L&D fund is estimated to be nearly $500 billion and rising by $200 billion annually.
    • A global transformation to a low-carbon economy is expected to require investments of at least $4-6 trillion a year.
    • The global stocktake refers to a five-year appraisal by countries of the impact of their actions to curb climate change.

    How realistic is the establishment of LDF?

    • To some extent, all this is immaterial.
    • Few believe that an UN-sponsored “loss and damage” fund will ever transfer the hundreds of billions that would be needed to offset the damage done by climate change.
    • COP27 itself dropped several hints that money for loss and damage could be found in what is called a “mosaic” of sources in existing global, regional and national financial institutions.

    Way forward

    • Mitigation, adaptation and loss and damage are inextricably linked.
    • Faster, more ambitious decarbonization will reduce the bill for adaptation.
    • Better mitigation and adaptation will mean that less money has to be spent rebuilding after disasters.

    Conclusion

    • LDF is largely a first concrete step towards the institutionalization of climate finance.
    • Delivering such funding will require a swift and comprehensive transformation of the financial system.
  • Climate Change and the role of Panchayat Raj Institutes (PRI’s)

    Panchayat

    Context

    • If India has to achieve the set of goals enunciated in the ‘Panchamrit’ resolution of the COP26 climate summit in Glasgow 2021, it is necessary that Panchayati raj institutions, the third tier of government which are closest to the people are involved.

    Climate change and rural area

    • Major impact on rural areas: The greater variability in rainfall and temperatures, etc. experienced of late has directly affected the livelihood and well-being of millions of rural households.
    • PRI excluded from National action plan: India’s National Action Plan on Climate Change 2008 identifies a range of priority areas for coordinated intervention at the national and State levels. However, there would have been better results had Panchayati raj institutions been given a greater role.
    • Decentralization of climate efforts are necessary: Through the ongoing decentralization process which ensures people’s participation, panchayats can play a crucial and frontline role in coordinating effective responses to climate risks, enabling adaptation and building climate-change resilient communities.

    What is carbon neutrality?

    • Zero carbon production:
    • The climate change discussion also focuses on the emerging and widely accepted concept of ‘carbon neutrality’ which puts forth the notion of zero carbon developments, nature conservation, food, energy and seeds sufficiency, and economic development.
    • As human activities are the cause of the current climate crisis, mitigating greenhouse gas emissions and adapting to growing and extreme weather events are critical.
    • Zero carbon development which promotes sustainable living is the effective solution to reducing anthropogenic emissions and improving climate resilience.

    Panchayat

    Efforts of Panchayat raj institutes to fight climate change: Case study of Meenangadi

    • Carbon neutral Meenangadi: In 2016, the panchayat envisaged a project called ‘Carbon neutral Meenangadi’, the aim being to transform Meenangadi into a state of carbon neutrality. There were campaigns, classes and studies to begin with. An awareness programme was conducted initially. A greenhouse gases emission inventory was also prepared. The panchayat was found to be carbon positive.
    • Implementation of Multi-sectoral schemes: An action plan was prepared by organising gram Sabha meetings. Socio-economic surveys and energy-use mapping were also carried out. Several multi sector schemes were implemented to reduce emissions, increase carbon sequestration, and preserve the ecology and bio-diversity.
    • Tree plantation Initiative: ‘Tree banking’ was one of landmark schemes introduced to aid carbon neutral activities which encouraged the planting of more trees by extending interest-free loans. Interestingly 1,58,816 trees were planted which have also been geo-tagged to monitor their growth.
    • People’s participation: The entire community was involved in the process, with school students, youth, and technical and academic institutions given different assignments. Five years have passed and the changes are visible. Local economic development was another thrust area where LED bulb manufacturing and related micro-enterprises were initiated.

    Panchayat

    Government of India’s effort to support climate change: ‘Clean and Green Village’

    • SDG theme: The Ministry of Panchayati Raj has focused its attention on localising the Sustainable Development Goals (SDGs) on a thematic basis.
    • Various activities delegated to PRI: ‘Clean and Green Village’ has been identified as the fifth theme where panchayats can take up activities on natural resource management, biodiversity protection, waste management and afforestation activities.
    • Documentation of best practices: According to the latest data, 1,09,135-gram panchayats have prioritised ‘Clean & Green Village’ as one of their focus areas for 2022-23. The Ministry has highlighted the need for the documentation of best practices and for wider dissemination.
    • Integrated panchayat development plan: The net result is that many panchayats are coming forward with their eco plans. The integrated Panchayat Development Plan prepared by all panchayats is a stepping stone towards addressing many of the environmental concerns of villages.

    Conclusion

    • In today’s age of rapid technological advancements and digital transformation, India’s rural local bodies are silently contributing their strength to ensuring the global target of carbon neutrality, as envisaged in the UN conference on climate change.

    Mains Question

    Q. What role PRIs can play in a fight against climate change? What is the scheme of “Clean and Green Village” of Ministry of Panchayat Raj?

  • What is the Koronivia Joint Work on Agriculture (KJWA)?

    India has expressed its concern over the draft decision text to implement the Koronivia Joint Work on Agriculture.

    What is the news?

    • India said developed countries are blocking a pro-poor and pro-farmer decision by insisting on expanding the scope for mitigation to agriculture.
    • Developed countries are thereby compromising the very foundation of food security in the world.

    What is the Koronivia Joint Work?

    • The KJWA is a decision under the United Nations Framework Convention on Climate Change (UNFCCC).
    • It seeks to recognize the unique potential of agriculture in tackling climate change.
    • It emphasizes reducing emissions of greenhouse gases due to the agriculture sector.
    • The Koronivia decision addresses six interrelated topics on soils, nutrient use, water, livestock, methods for assessing adaptation, and the socio-economic and food security dimensions of climate change across the agricultural sectors.

    India’s arguments against Koronivia joint work

    • India said that agricultural emissions are not “luxury” emissions but “survival” emissions of the poor.
    • The world is facing a climate crisis today because of the excessive historic cumulative emissions by the developed nations.
    • These nations are unable to reduce their emissions domestically by any worthwhile change in their lifestyles.
    • Rather, they are searching for cheaper solutions abroad.
    • In most developing countries across the world, agriculture is done by small and marginal farmers who toil hard and brave the vagaries of extreme weather and climate variability to ensure food security.

    Back2Basics: Agricultural Emissions

    koronivia

    • Farms emitted 6 billion tonnes of GHGs in 2011, or about 13 percent of total global emissions.
    • That makes the agricultural sector the world’s second-largest emitter, after the energy sector (which includes emissions from power generation and transport).
    • Most farm-related emissions come in the form of methane (CH4) and nitrous oxide (N2O).
    • Cattle belching (CH4) and the addition of natural or synthetic fertilizers and wastes to soils (N2O) represent the largest sources, making up 65 percent of agricultural emissions globally.
    • Smaller sources include manure management, rice cultivation, field burning of crop residues, and fuel use on farms.

  • Is climate change affecting global health?

    A recent report by Lancet, has traced in detail the intimate link between changing weather events and their impact on the health of people.

    What is the news?

    • The 2022 Lancet Countdown on Health and Climate Change: Health at the Mercy of Fossil Fuels points out that the world’s reliance on fossil fuels increases the risk of disease, food insecurity and other illnesses related to heat.

    Impact of climate change on health

     (1) Extreme Events

    • Heatwaves: The Lancet report indicates that rapidly increasing temperatures exposed vulnerable populations (adults above 65 years old and children younger than 1) to 3.7 billion more heatwave days in 2021 than annually in 1986–2005.
    • Shift in patterns: There is no doubt that events such as floods, droughts and recurrent cyclones are direct outcome of climate change.

    (2) Impact on health

    • Infectious diseases: The changing climate is affecting the spread of infectious disease, raising the risk of emerging diseases and co-epidemics. For instance, coastal waters are becoming more suited for the transmission of Vibrio pathogens.
    • More vector borne diseases: The number of months suitable for malaria transmission has increased in the highland areas of the Americas and Africa.
    • More lives loss: The WHO has predicted that between 2030 and 2050, climate change is expected to cause approximately 2,50,000 additional deaths per year, from malnutrition, malaria, diarrhoea and heat stress.
    • Others: Low air quality, Rise in zoonotic diseases.

    (3) Food security

    • Crop loss: Higher temperatures threaten crop yields directly, with the growth season shortening for many cereal crops.
    • Supply chain disruptions: Extreme weather events disrupt supply chains, thereby undermining food availability, access, stability, and utilisation.
    • Malnutrition: The prevalence of undernourishment increased during the COVID-19 pandemic, and up to 161 million more people faced hunger in 2020 than in 2019.

    Way forward

    • Health-centred response: A health-centred response to the coexisting climate, energy, and cost-of-living crises provides an opportunity to deliver a healthy, low-carbon future.
    • Realization of the problem: The governments’ commitment to assess and address the threats from climate change, are positive signs, the report stresses.
    • Holistic approach: This is the way a health-centred response would work – it would reduce the likelihood of the most catastrophic climate change impacts, while improving energy security and creating an opportunity for economic recovery.
    • Shift in dietary patterns: The report also calls for an accelerated transition to balanced and more plant-based diets, as that would help reduce emissions from red meat and milk production, and prevent diet-related deaths.
    • Easing the healthcare: The report emphasizes reducing the strain on health-care providers, and leading to more robust health systems.

  • MARS A new alert system to detect Methane emissions

    MARS

    Context

    • A new satellite-based system will now help governments detect methane emissions and tackle them. The Methane Alert and Response System (MARS) was launched at the 27th Conference of Parties (COP27) to the United Nations Framework Convention on Climate Change in Sharm El-Sheikh, Egypt.

    What is Methane Alert and Response System (MARS)?

    • MARS is a part of global efforts to slow climate change by tracking the global warming gas.
    • The system will be the first publicly available global system to connect methane detection to notification processes transparently.
    • The data-to-action platform was set up as part of the UN Environment Programme’s (UNEP) International Methane Emissions Observatory (IMEO) strategy to get policy-relevant data into the right hands for emissions mitigation.

    MARS

    How the “MARS” will work?

    • The Methane Alert and Response System, or MARS, will integrate data from a large number of existing and future satellites to identify significant methane emission events anywhere in the world.
    • It will send out notifications to the relevant stakeholders and support and track mitigation progress.
    • According to the UN statement MARS will track the large point emission sources, mainly in the fossil fuel industry, but with time, would be able to detect emissions from coal, waste, livestock and rice fields as well.
    • UNEP will continue to monitor the event location and make the data and analysis available to the public between 45 and 75 days after detection.

    MARS

    Methane a dangerous greenhouse gas

    • A major greenhouse gas: Methane is the second-most common of the six major greenhouse gases, but is far more dangerous than carbon dioxide in its potential to cause global warming.
    • One of major contributor of GHG emissions: Contribution Accounting for about 17 per cent of the current global greenhouse gas emissions.
    • One of the key reasons behind Temperature rise: Methane is blamed for having caused at least 25 to 30 per cent of temperature rise since the pre-industrial times.
    • Methane largely a Sectoral gas: Unlike carbon dioxide, methane is largely a sectoral gas, and there are only a few sources of emission.
    • Few sources large emissions of methane: The global warming potential of methane is about 80 times that of carbon dioxide. It accounts for a small portion of human-induced greenhouse gas emissions compared to carbon dioxide.

    MARS

    Why such alert system is necessary?

    • To achieve the target set by Global methane pledge: At the Glasgow climate conference last year, nearly 100 countries had come together in a voluntary pledge the Global Methane Pledge to cut methane emissions by at least 30 per cent by 2030 from the 2020 levels. More countries have joined in this initiative since then, bringing the total to nearly 130.
    • To keep the temperature, rise below 5-degree Celsius: A 30 per cent reduction in methane emissions by 2030 is expected to result in avoiding 0.2 degree rise in temperature by the year 2050, and is considered absolutely essential in the global efforts to keep the temperature increase below the 1.5-degree Celsius target. This is a global, not a national reduction target.
    • Reducing methane emissions from the atmosphere provides multiple benefits: Methane being a sectoral gas with few sources of emission, it is possible to cut down on methane emissions without having widespread impact on the economy, a reduction in methane emissions brings big benefits in a short time.
    • MARS Provides technical and advisory to the partners: If requested, MARS partners will also provide technical or advisory services, such as help in assessing mitigation opportunities

    All you need to know about Conference of Parties (COP).

    • Unless the parties decide otherwise, every year The United Nations Framework Convention on Climate Change (UNFCCC) convenes what is called a Conference of Parties (COP), a meeting that brings together leaders and delegates from around the world to strengthen their commitments and actions against specific climate change goals.
    • The parties are the 198 countries that ratified the UNFCCC.
    • The UNFCCC is an international treaty focused on preventing dangerous human interference with the climate system, primarily by stabilizing greenhouse gas (GHG) emissions.

    Conclusion

    • Cutting methane is the fastest opportunity to reduce warming and keep 1.5°C within reach, and this MARS a new alert and response system is going to be a critical tool for helping all of us deliver on the Global Methane Pledge.

    Mains Question

    Q. Methane is thought to be 80 times more efficient than carbon dioxide at trapping atmospheric heat in the 20 years following its release. Discuss how MARS a new alert system would be helpful to keep the temperature rise below 1.5 degree Celsius?

  • Elephant in the Room at COP 27- Energy Equity

    COP

    Context

    • 27th Conference of Parties (COP27, beginning November 6, in Egypt) of the United Nations Framework Convention on Climate Change (UNFCCC).

    Realization of climate action: Birth of UNFCCC

    • The idea led to the formation of the United Nations Framework for Climate Change Convention (UNFCCC, also known as ‘The Convention’) in 1992, at the Earth Summit in Rio de Janeiro.
    • The convention divided the countries on the basis of their differing commitments: Annex I and II consisted of industrialized and developed countries and Non-Annex I comprised developing countries.

    COP

    Summary of COP26

    • Inadequate reduction commitment: In the runup to COP26, last year in Glasgow, several developed countries had declared their intention to reach net zero emissions by 2050. These declarations did not square with the requirements of “keeping 1.5 deg. C alive”.
    • Global carbon budget: Four fifths of the global carbon budget to limit warming to 1.5°C (with 50% probability) has already been exhausted. Developed countries are responsible for more than half of these historical CO2 emissions. Nevertheless, there was much celebration of these targets.
    • Politics over phasing out coal: There was also high drama at COP26, with moral grandstanding by many developed country negotiators who invoked the future of their children, because India and other countries understandably balked at the singling out of any one fossil fuel for immediate action.
    • Developed countries didn’t meet the commitment: It is important to recall some of these shenanigans at COP26, as in the last year, it has become clear that developed countries may be unlikely to meet even the inadequate targets they have set, keeping to the trend of the last three decades.

    What is the present energy situation in developing countries?

    • Energy poverty concentrated in the developing countries: Global energy poverty is concentrated in the developing countries. In 2021, 733 million people had no access to electricity and almost 2.6 billion people lacked access to clean fuels and technologies.
    • The average per capita energy: Energy use of the richest 20 countries is 85 times higher than that of the 20 poorest countries. Addressing this stark energy poverty in developing countries is important because there is a strong correlation between energy supply and human development.
    • The average annual per capita electricity: Electricity consumption of sub-Saharan Africa is 487 kilowatt hours (kWh), alongside an infant mortality rate of 73 per 1,000 live births; maternal mortality ratio of 534 per 1,00,000 live births, and per capita GDP of $1,645. On the other hand, the OECD group of countries have a per capita electricity consumption of 7,750 kWh, corresponding to an infant mortality rate of seven, maternal mortality ratio of 18, and per capita GDP of $42,098.
    • Slowdown due to lack of energy: The reality of global inequality was acutely evident during the COVID19 pandemic. Several countries in Africa, Asia and Latin America are facing severe agricultural and industrial slowdowns in the post pandemic period.
    • The lack of reliable energy infrastructure: Infrastructure unavailability has compounded the difficulties and has multidimensional impacts across developmental indicators. In 2022, these inequalities have been aggravated by soaring energy and food prices.
    • Rising cost of living: Several countries face a severe rise in the cost of living and nearly 70 million additional people are estimated to fall below the poverty line of $3.20 per person per day. Poor and vulnerable communities in the energy importing countries of the global South suffer the most. Almost 90 million people in Asia and Africa, who gained access to electricity recently, cannot afford to pay their energy bills.
    • No acknowledgement of problem by developed countries: In this background, COP27 affords a critical moment to acknowledge and address the concerns surrounding energy access and security in developing countries. Unfortunately, these longstanding problems of the global South have been ignored by developed country governments, academia, and civil society. At a time when the language of energy poverty and security is re-entering the northern vocabulary, it is time to call out the hypocrisy of the advice on fossil fuel use given by the north to some of the world’s poorest regions since the Paris Agreement was signed.

    COP

    How developed countries are hypocritic about energy use and commitments?

    • Fossil fuel as primary energy source: In the United States, 81% of primary energy is from fossil fuels. In Europe, fossil fuels constitute 76% of the energy consumption (coal, oil, and natural gas contribute 11%, 31%, and 34% respectively).
    • Negligible efforts for decarbonization: Thirty years after acknowledging the problem of anthropogenic global warming and committing in the UNFCCC, to take the lead in climate change mitigation, the level of decarbonization in the global North has been minuscule.
    • Increasing coal consumption: In July 2022, the European Union (EU) voted to classify the use of natural gas for some uses as “green and sustainable”. Natural gas was responsible for 7.5 billion tonnes of CO2 (i.e., 23% of the total CO2 by the major fossil fuels), in 2020. Additionally, in 2022, even coal consumption in the U.S. and the EU is estimated to increase by 3% and 7%, respectively.
    • Double standard for fossil fuel: These same developed countries argue that green energy constitutes a great business opportunity for developing countries as it has become cheaper. They have used this dubious argument to dismiss differentiation between developed and developing countries and are lobbying for banning the financing of any fossil fuel projects in some of the poorest countries.

    What should be the agenda of developing countries at COP 27?

    • Bring the energy poverty issue: At COP27, the global South must put the question of its energy poverty and the severe global inequalities in energy access squarely at the Centre of all discussions.
    • Achieving SDGs with climate actions: We need to achieve zero hunger, zero malnutrition, zero poverty, and universal wellbeing even as we collectively contribute to ensuring effective climate action.
    • No empty commitments: As the strapline for COP27 (“Together for Implementation”) suggests, we must work together to ensure that these developmental goals are not side-lined, as they were at COP26, in the pursuit of hollow declarations of net zero targets three decades into the future.

    COP

    Conclusion

    • A developing country leadership at COP27 can ensure effective discussions, based on equity and common but differentiated responsibilities and respective capabilities, on the relative responsibilities and sharing of mitigation and adaptation burdens while coping with loss and damage.

  • LT-LEDS (Long Term-Low Emission Development Strategy)

    strategy

    India has announced its long-term strategy to transition to a “low emissions” pathway at the United Nations Conference of Parties (COP) ongoing in Sharm el-Sheikh, Egypt.

    What are LT-LED Strategy?

    • The LT-LEDS are qualitative in nature and are a requirement emanating from the 2015 Paris Agreement.
    • Hereby, countries explain how they will transition their economies beyond achieving near-term NDC targets.
    • It signifies their path towards the larger climate objective of cutting emissions by 45% by 2030 and achieve net zero around 2050.

    BACKGROUND

    What is the meaning of Net Zero?

    • A state in which a country’s emissions are compensated by absorption and removal of greenhouse gases (GHGs) from the atmosphere is called Net Zero State; it is also referred to as carbon-neutrality.
    • It is done through natural processes as well as futuristic technologies such as carbon capture and storage.

    Nationally Determined Contributions (NDCs): 

    • To achieve the targets under the agreement, the member countries must submit the targets themselves, which they believe would lead to substantial progress towards reaching the Paris temperature goal.
    • Initially, these targets are called Intended Nationally Determined Contributions (INDCs).
    • They are converted to NDCs when the country ratifies the agreement.

    Key announcements by India

    • Nuclear energy: India is set to expand its nuclear power capacity by at least three-fold in the next decade.
    • Green hydrogen: India aims for becoming an international hub for producing green hydrogen through the National Hydrogen Mission.
    • Ethanol blending: India aspires to maximise the use of electric vehicles, with ethanol blending to reach 20% by 2025 (it is currently 10%) and a “strong shift” to public transport for passenger and freight traffic.
    • Energy efficiency: India will also focus on improving energy efficiency by the Perform, Achieve and Trade (PAT) scheme.
    • Carbon sequestration: India’s forest and tree cover are a net carbon sink absorbing 15% of CO2 emissions in 2016, and it is on track to fulfilling its NDC commitment of 2.5 to 3 billion tonnes of additional carbon sequestration in forest and tree cover by 2030.

    Hurdles in achieving net-zero

    • Huge cost of transition: The transition to low carbon pathway will entail several costs amounting to several trillion dollars. It involves the development of new technologies, new infrastructure, and other transaction costs.
    • No climate finance mechanism: Provision of climate finance by developed countries will play a very significant role and needs to be considerably enhanced.

    Significance of India’s LTS

    • India’s long-term strategy (LTS) follows up on the net zero pledge.
    • It clearly outlines key interventions across sectors that are going to be the focus of India’s efforts.

    Considerations made by India

    India’s approach is based on the following four key considerations that underpin its long-term low-carbon development strategy:

    1. India has contributed little to global warming: its historical contribution to cumulative global GHG emissions being minuscule despite having a share of ~17% of the world’s population.
    2. Huge domestic energy demand: India has significant energy needs for development.
    3. National circumstances: India is committed to pursuing low-carbon strategies for development and is actively pursuing them, as per national circumstances
    4. India needs to build climate resilience: It is the capacity of social, economic and ecosystems to cope with a hazardous event or trend or disturbance.

    • An initiative led by the UAE and Indonesia, the MAC includes India, Sri Lanka, Australia, Japan, and Spain.
    • It seeks to educate and spread awareness worldwide on the role of mangroves in curbing global warming and its potential as a solution for climate change.
    • Under MAC, UAE intends to plant 3 million mangroves in the next two months, in keeping with UAE’s COP26 pledge of planting 100 million mangroves by 2030.

    Working of MAC

    • MAC would work on a voluntary basis. It means that there are no real checks and balances to hold members accountable.
    • Instead, the parties will decide their own commitments and deadlines regarding planting and restoring mangroves.
    • The members will also share expertise and support each other in researching, managing and protecting coastal areas.

    Why protect mangroves?

    • Infrastructure projects — industrial expansion, shifting coastlines, coastal erosion and storms, have resulted in a significant decrease in mangrove habitats.
    • Between 2010 and 2020, around 600 sq km of mangroves were lost of which more than 62% was due to direct human impacts, the Global Mangrove Alliance said in its 2022 report.

    Importance of mangroves

    • Biodiversity: Mangrove forests — consisting of trees and shrub that live in intertidal water in coastal areas — host diverse marine life.
    • Fishing grounds: They also support a rich food web, with molluscs and algae-filled substrate acting as a breeding ground for small fish, mud crabs and shrimps, thus providing a livelihood to local artisanal fishers.
    • Carbon sinks: Equally importantly, they act as effective carbon stores, holding up to four times the amount of carbon as other forested ecosystems.
    • Cyclone buffers: When Cyclone Amphan struck West Bengal in May, its effects were largely mitigated by the Sundarbans flanking its coasts along the Bay of Bengal.

    Threats to Mangroves

    • Anthropogenic activities: They are a major threat to the mangroves. Urbanization, industrialization and the accompanying discharge of industrial effluents, domestic sewage and pesticide residues from agricultural lands threaten these fragile ecosystems.
    • Saltpan and aquaculture: This causes huge damage to the mangroves. Shrimp farming alone destroyed 35,000 hectares of mangroves worldwide.
    • Destruction for farming: 40% of mangroves on the west coast has been converted into farmlands and other settlements in just 3 decades.
    • Sea-level rise: This is another challenge to these mangroves- especially on the Bay of Bengal coast.

    Mangroves in India

    • India holds around 3 percent of South Asia’s mangrove population.
    • Besides the Sundarbans in West Bengal, the Andaman region, the Kutch and Jamnagar areas in Gujarat too have substantial mangrove cover.

    How can India benefit from MAC?

    • India is home to one of the largest remaining areas of mangroves in the world — the Sundarbans.
    • It has years of expertise in restoration of mangrove cover that can be used to aid global measures in this direction.
    • The move is in line with India’s goal to increase its carbon sink.

  • Energy Transition Accelerator (ETA): A new carbon offset scheme by the US

    eta

    The US has unveiled a new carbon offset scheme called Energy Transition Accelerator (ETA) for climate finance.

    Energy Transition Accelerator (ETA)

    • ETA is carbon offset plan that will allow companies to fund clean energy projects in developing countries and gain carbon credits that they can then use to meet their own climate goals.
    • The plan will be developed by the US along with the Bezos Earth Fund and the Rockefeller Foundation.
    • It would receive inputs from public and private
    • The concept is to put the carbon market to work, deploy capital otherwise undeployable, and speed up the transition from dirty to clean power.

    Benefits of ETA

    • It may be good for renewable energy projects for sure and for those coal plants that are very old and unviable and which India wishes to shut down.
    • The scheme comes at a time when there is growing mistrust among developing countries about developed nations failing to deliver on climate finance commitments.

    Limitations of ETA

    • The proposed initiative would be insufficient to make up for the lack of funding from rich countries.
    • What developing countries need is predictable finance – not offset markets.
    • The proposed initiative cannot make up for the US’s failure to provide its fair share of climate finance – an estimated $40 billion of the unmet goal of $100 billion a year.

    Conclusion

    • ETA appears to be a substitute for deep decarbonization needed within the US and other industrialized countries.
    • For developing countries like India, the first priority would be to meet their own targets and not provide offsets for reductions in developed nations.
