    Why in the News?

    In India, current carbon credit projects by private organisations should be reviewed to ensure they are fair and work effectively.

    What are the current carbon credit projects? 

    • Collaborative Initiatives: NABARD, ICAR, and State Universities have listed five agricultural carbon credit projects in the Verra registry to promote sustainable agriculture.
    • Carbon Farming Projects: Over 50 projects targeting 1.6 million hectares aim to generate 4.7 million carbon credits annually, but none are registered, leaving farmers without financial benefits.

    Note: Verra is a carbon credit registry that manages the Verified Carbon Standard (VCS), ensuring high-quality carbon credit projects and facilitating transparent trading of carbon credits.

    What are the key challenges facing agricultural carbon markets?

    • Lack of Communication and Training: A significant portion of farmers (45%) reported inadequate communication regarding carbon farming practices, and over 60% lacked training in new techniques. This gap in knowledge can hinder the effective implementation of sustainable practices necessary for generating carbon credits.
    • Exclusion of Marginalized Communities: Many existing carbon farming projects have not adequately included smallholders and marginalized communities, with women representing only 4% of participants. This lack of inclusivity limits the socioeconomic benefits that carbon markets could provide to a broader segment of the farming population.
    • Financial Incentives: A notable 28% of farmers discontinued sustainable practices by the second year due to insufficient financial incentives. The absence of timely payments for carbon credits further discourages participation and undermines project sustainability.
    • Unregistered Projects: Despite over 50 agricultural carbon farming projects being listed in the Verra registry, none have been officially registered, meaning no carbon credits have been issued and farmers have not received any financial compensation.
    • Quality Assurance: Ensuring that projects deliver reliable environmental benefits is crucial. If projects fail to produce credible carbon credits, it may lead to a loss of confidence among buyers, which would ultimately deprive farmers of income and discourage sustainable practices.

    How can farmers be incentivized to participate in carbon markets?

    • Higher Prices for Inclusive Projects: Offering premium prices for carbon credits from projects that actively include smallholders and marginalized communities can encourage broader participation and ensure equitable benefits.
    • Effective Communication and Training Programs: Establishing robust communication channels and providing regular training on sustainable agricultural practices will empower farmers to adopt new techniques confidently.
    • Guaranteed Timely Payments: Implementing a system that ensures farmers receive prompt payments for their carbon credits will enhance trust in the market and encourage ongoing participation in sustainable practices.
    • Collaboration with Research Institutions: Partnering with national and international research organizations can help identify suitable regions for carbon farming, ensuring that interventions are effective and do not compromise food security.
    • Bundling Small Farmers into Cooperatives: Creating Farmer Producer Organizations (FPOs) can help reduce transaction costs, improve bargaining power, and facilitate easier access to carbon markets for smallholder farmers.

    What role do technological advancements play in enhancing agri-carbon markets?

    • Improved Measurement Techniques: Advances in digital technologies such as remote sensing, satellite imagery, drones, and sensors will enhance the monitoring, reporting, and verification (MRV) processes essential for assessing soil carbon levels and GHG emissions accurately.
    • Data Accessibility: The increasing availability of technology will allow farmers to access real-time data on their farming practices, enabling them to make informed decisions that align with sustainable methods required for carbon credit generation.
    • Enhanced Project Implementation: Technology can streamline project management by facilitating better communication between stakeholders, tracking progress, and ensuring compliance with additionality and permanence criteria necessary for successful carbon credit projects.
    • Scalability of Projects: Digital tools can help scale successful carbon farming initiatives by providing frameworks that can be replicated across different regions, thus expanding the reach of agricultural carbon markets in India.

    Way forward: 

    • Strengthen Inclusivity and Farmer Incentives: Promote inclusive projects that actively engage smallholders and marginalized communities by offering premium prices for carbon credits, ensuring timely payments, and bundling farmers into cooperatives for better market access.
    • Leverage Technology for Efficiency: Utilize advanced digital tools like remote sensing and real-time data systems to improve monitoring, reporting, and verification (MRV) processes, enhance project scalability, and ensure effective implementation of carbon credit initiatives.

  • Arctic Tundra is emitting more Carbon than it absorbs: NOAA

    Type:
    Subjects: ,
    GS Papers: ,

    Why in the News?

    • The Arctic Tundra, a frozen treeless biome, has traditionally served as a carbon sink, storing vast amounts of carbon for thousands of years.
      • However, recent changes in this ecosystem are turning it into a source of greenhouse gases (GHGs), primarily carbon dioxide (CO2) and methane (CH4) according to National Oceanic and Atmospheric Administration (NOAA).

    What is Arctic Tundra?

    • Arctic Tundra is cold, treeless biome located in the northernmost regions of Earth, primarily within the Arctic Circle.
    • Climate:
      • Experiences long, harsh winters and short, cool summers.
      • Temperatures range from -28°C in winter to 3°C in summer.
      • Ground is permanently frozen, restricting plant root growth and shaping the ecosystem.
      • Experiences 24-hour daylight in summer and long polar nights in winter.
    • Biodiversity and Vegetation:
      • Limited to low-growing vegetation like mosses, lichens, grasses, and small shrubs, adapted to short growing seasons.
      • Hosts animals like Arctic foxes, polar bears, caribou, and migratory birds, though overall biodiversity is low.
    • Adaptations:
      • Animals: Thick fur and fat layers in species like polar bears to survive extreme cold.
      • Plants: Shallow roots for quick nutrient absorption during short summers.

    How does the Arctic Tundra store Carbon?

    • The Arctic tundra stores carbon primarily through a process where plants absorb carbon dioxide (CO2) from the atmosphere via photosynthesis.
      • This carbon gets trapped in the soil and organic matter (plants and animals) that accumulate over time.
    • The cold Arctic climate slows the decomposition of plant and animal remains, meaning that organic materials, including carbon, remain locked in the permafrost.
      • This permafrost acts as a natural storage system, preventing CO2 from being released back into the atmosphere.
    • Scientists estimate that the Arctic tundra holds about 1.6 trillion metric tonnes of carbon, which is roughly double the amount of carbon in the Earth’s atmosphere.

    Why is the Arctic Tundra emitting more carbon than absorbing it?

    • Rising temperatures in the Arctic are causing the permafrost to thaw at an accelerated rate.
      • When permafrost thaws, microbes in the soil become active, breaking down the organic material trapped in the frozen ground, which results in the release of carbon dioxide (CO2) and methane (CH4), two potent greenhouse gases.
      • The Arctic has been warming at a rate four times faster than the global average.
      • 2024 was the second-warmest year on record for the region, contributing significantly to the thawing of the permafrost.
    • Wildfires in the Arctic have become more frequent and intense, further accelerating the thawing of permafrost. Wildfire smoke also contributes to the release of greenhouse gases.
    • Between 2001 and 2020, the combination of rising temperatures and increased wildfires led to the Arctic tundra releasing more carbon than it absorbed, marking a significant shift in its role from a carbon sink to a carbon emitter.

  • Green hydrogen and the financing challenge

    Type:
    Subjects: ,
    GS Papers: ,

    Why in the news?

    India aims to produce 5 million metric tonnes of green hydrogen annually by 2030 to lead in the sector and reduce emissions, but the high costs of financing may hinder this goal.

    Hydrogen fuel comes in three types:

    • Grey hydrogen (produced from natural gas), Blue hydrogen (Grey hydrogen with carbon capture), and Green hydrogen (produced using renewable energy through electrolysis, with no emissions).

    What are the key financial barriers to scaling green hydrogen production?

    • High Production Costs: The cost of producing green hydrogen is significantly higher ($5.30-$6.70 per kg) compared to traditional grey/blue hydrogen ($1.9-$2.4 per kg). This price disparity makes green hydrogen economically uncompetitive and deters investment and offtake.
    • High Weighted Average Cost of Capital (WACC): In emerging markets like India, higher perceived risks increase borrowing costs. This results in a high WACC, which heavily influences the Levelised Cost of Electricity (LCOE) and the overall cost of green hydrogen production.
    • High Electrolyzer Costs: The current costs of electrolyzers, ranging from $500-1,400/kW for alkaline and $1,100-1,800/kW for proton exchange membrane systems, further strain the financial viability of green hydrogen projects.
    • Scaling Challenge: Green hydrogen production costs can only decrease with scaled production, but scaling up requires financial viability. The market faces a catch-22 situation: without economies of scale, production remains expensive, and without lowering costs, scaling is unfeasible.

    How can innovative financing mechanisms be developed?

    • Blended Finance Models: Combining public and private capital can help lower risks and make investments in green hydrogen more attractive. Government-backed financial instruments or concessional loans can reduce borrowing costs, lowering WACC.
    • Green Bonds and Climate Financing: The issuance of green bonds to raise capital for renewable energy projects can provide long-term funding at lower costs. These bonds can appeal to investors with an interest in sustainable investments.
    • Private-Public Partnerships (PPP): Collaborations between government and private sectors can help mitigate risks and ensure the financing of green hydrogen projects. To attract private investors, governments can provide financial support through incentives, subsidies, or tax breaks.
    • Carbon Credits and Offtake Agreements: Green hydrogen projects could leverage carbon credits or long-term offtake agreements to secure steady revenue streams, which would increase investor confidence and help finance production scale-up.

    What role do policy frameworks play in facilitating investment in green hydrogen?

    • Incentives and Subsidies: Government policies offering subsidies, tax incentives, or feed-in tariffs can help offset the high initial costs of green hydrogen production and encourage private investment.
    • Long-Term Policy Clarity: Clear, stable, and long-term policy frameworks provide certainty to investors, reducing perceived risks and lowering the cost of capital. Such policies could include long-term targets for green hydrogen production, financing support, and infrastructure development.
    • Regulatory Support for Innovation: Governments can encourage innovation by providing regulatory frameworks that support new technologies, such as electrolyzers and advanced hydrogen storage solutions, ensuring the rapid scaling of green hydrogen.
    • Market Creation and Demand-Driven Initiatives: Policies that create demand for green hydrogen, such as mandatory usage targets for industries like steel, transportation, or chemicals, can drive off-take agreements and ensure market stability.

    Distribution: ,

    Why in the News?

    A recent study suggests that the Arctic Ocean may experience its first ice-free day—where sea ice falls below one million square kilometres—by 2030, or even sooner.

    Key Highlights of the Study

    • First Ice-Free Day Prediction: The study predicts that the Arctic Ocean could experience its first ice-free day (less than one million square kilometres of sea ice) by 2030, or even sooner, depending on climatic conditions.
    • Simulations and Models:
      • 11 different climate models were used to run 366 simulations from 2023 to 2100 to assess the future of Arctic sea ice.
      • Most simulations predict the ice-free day within 7 to 20 years, with some models suggesting it could happen as early as September 2027.
    • Conditions for Ice-Free Day: The occurrence of an ice-free day will depend on a combination of unusually warm seasons and stormy weather, which accelerates the melting of the sea ice.
    • Impact on Sea Ice: Once the first ice-free day occurs, it could be followed by an ice-free period lasting between 11 to 53 days, potentially leading to the first ice-free month.

    How does the Arctic Tundra store Carbon?

    • The Arctic tundra stores carbon primarily through a process where plants absorb carbon dioxide (CO2) from the atmosphere via photosynthesis.

    Why does it matter?

    • Climate Change Acceleration: The loss of sea ice will amplify the Albedo effect, causing the Arctic region to absorb more sunlight and heat, which will accelerate global warming and trigger extreme weather events in mid-latitudes.
    • Rising Sea Levels: The loss of Arctic ice contributes to sea level rise, with potential long-term impacts on coastal populations and ecosystems, particularly if the Greenland ice sheet melts completely, which could raise sea levels by 6 meters.
    • Ecosystem and Species Impact: The melting of sea ice will threaten species that rely on the ice for habitat, such as polar bears, walruses, and reindeer, disrupting the Arctic food chain.
    • Human and Infrastructure Threats: Arctic communities and their infrastructure are at risk as the region warms at four times the global average, threatening the livelihoods of people living in these areas.

    Back2Basics: Albedo Effect

    arctic albedo

    • It refers to the measure of how much sunlight is reflected by a surface.
    • It is expressed as a percentage; a surface with a high albedo reflects more sunlight, while a surface with a low albedo absorbs more.
    • Light-colored surfaces like ice and snow have high albedo, reflecting most of the sunlight, whereas dark surfaces like oceans and forests have low albedo, absorbing more heat.

  • Beijing’s War Against Air Pollution

    Type:
    Subjects: ,
    GS Papers: ,

    Why in the News?

    In 2015, Beijing had an annual average Air Quality Index (AQI) of 144, comparable to Delhi’s current average of 155 in 2024. However, Beijing has since achieved a one-third reduction in its pollution levels, with the most notable decline occurring between 2013 and 2017.

    Why discuss Beijing in the context of Delhi?

    The comparison between Beijing and Delhi is significant due to their shared status as capitals of emerging economies facing severe air pollution challenges.  

    • Similar Pollution Levels: In 2015, Beijing had an average AQI of 144, comparable to Delhi’s current average of 155 for 2024. This similarity highlights the potential for improvement in Delhi, as Beijing has successfully reduced its pollution levels significantly since then.

    • Common Sources of Pollution: Both cities experience high pollution from similar sources, including vehicular emissions, coal combustion, and industrial activities. The regional contributions to air quality issues are also significant in both cases, particularly during winter months.
    • Need for Collective Action: Just as Beijing required a coordinated effort across its region to combat pollution, Delhi must engage neighboring areas in a collective strategy to effectively address its air quality crisis.

    What did Beijing do and how did it achieve it?

    • Phased and Strategic Planning: Implemented a 20-year anti-pollution programme in three phases (1998-2017) with local government autonomy and public participation to ensure gradual and sustainable progress.
      • 1998-2008: Initial groundwork.
      • 2009-2012: Strengthening regulations.
      • 2013-2017: Aggressive measures termed the “war against air pollution.
    • Energy Sector Transition: Shifted from coal to cleaner energy by renovating power plants, eliminating coal boilers, and replacing residential coal heating, reducing major emissions.
    • Transportation Reforms: Upgraded public transport infrastructure, introduced emission controls in vehicles, and phased out polluting vehicles with subsidies, reducing transportation-based pollutants.
    • Regional Collaboration and Investment: Partnered with five neighboring provinces for coordinated pollution control and increased financial investment sixfold to implement targeted measures effectively.

    • Financial Investment: A sixfold increase in investment over four years supported these initiatives, allowing for significant infrastructure improvements and regulatory enforcement.

    As a result of these efforts, major pollutants like sulfur dioxide and PM2.5 saw significant reductions (e.g., PM2.5 decreased by 59% between 2013-2017).

     

    What can Delhi learn from the Beijing experience?

    • Integrated Public Transport System: Establishing an efficient bus-metro system to reduce reliance on private vehicles is essential. Upgrading the bus fleet and enhancing last-mile connectivity can significantly improve public transport accessibility.
    • Energy Transition: Similar to Beijing’s shift away from coal, Delhi should diversify its energy sources by promoting renewable energy options like solar power while reducing dependence on coal-fired plants.
    • Regional Coordination: Pollution control efforts should extend beyond city limits to include neighboring regions, fostering collaboration similar to Beijing’s regional initiatives.
    • Public Advocacy for Clean Air: Encouraging citizen engagement in demanding accountability from the government can build political will for implementing necessary changes.
    • Political Will and Consistency: Addressing air pollution requires sustained political commitment and a long-term action plan rather than ad hoc measures that fail to tackle root causes.

    Way forward: 

    • Strengthen Policy Implementation and Regional Collaboration: Formulate and enforce a comprehensive, long-term pollution control policy with coordinated efforts involving Delhi and its neighboring states to address regional pollution sources effectively.
    • Promote Sustainable Infrastructure and Public Engagement: Invest in renewable energy, green public transport, and urban planning while fostering public participation and advocacy for clean air to ensure accountability and sustained progress.

  • Climate impact of exploring space passing below the radar

    Type:
    Subjects: ,
    GS Papers: ,

    Why in the News?

    The growing reliance on space technologies for climate monitoring highlights urgent environmental concerns, including orbital debris and system interference, necessitating swift international regulations to ensure sustainable space exploration practices.

    How do Rockets affect the environment?

    • Emissions from Launches: Every rocket launch releases significant amounts of carbon dioxide, black carbon, and water vapour into the atmosphere. Black carbon is particularly concerning as it absorbs sunlight much more effectively than carbon dioxide, exacerbating global warming.
    • Ozone Layer Depletion: Rocket propellants, especially those containing chlorine-based chemicals, contribute to the depletion of the ozone layer at high altitudes. This increases ground-level exposure to ultraviolet radiation and disrupts atmospheric circulation, negatively impacting global climate.
    • Satellite Ash: When satellites re-enter the atmosphere at the end of their missions, they burn up and release metallic ash into the middle layers of the atmosphere, which can harm the atmosphere and potentially alter climate patterns.
    • Manufacturing Footprint: The production of satellites involves energy-intensive processes that have large carbon footprints due to the extraction and processing of metals and composite materials.
    • Space Mining Potential: Future activities such as space mining could lead to increased industrial activity both in space and on Earth, further contributing to environmental impacts.

    What are the Barriers to space sustainability?

    • Lack of Regulation: Current space activities operate outside international sustainability frameworks like the Paris Agreement. There are no clear guidelines for emissions from rockets and satellites, allowing unchecked growth that contributes to global warming.
    • Overcrowding in Low Earth Orbit (LEO): The increasing number of satellites and debris threatens to overcrowd LEO, making future missions more expensive and complicating access to space as a shared resource.
    • Need for International Cooperation: Effective regulation requires collaboration through international bodies like the Committee on the Peaceful Use of Outer Space (COPUOS) to create enforceable standards for emissions and debris management.
    • Outdated Treaties: Existing frameworks such as the Outer Space Treaty lack binding provisions that address environmental impacts, limiting their effectiveness in promoting responsible space use.

    What would be the innovative solutions?

    • Reusable Rockets: Developing reusable rockets can significantly reduce manufacturing waste and lower costs by allowing components to be used in multiple missions. However, these rockets may be heavier, increasing fuel consumption, and require costly refurbishments.
    • Cleaner Fuels: Transitioning to cleaner fuels such as liquid hydrogen or biofuels can minimize harmful emissions during launches. However, current hydrogen production methods often rely on non-renewable energy sources, undermining its environmental benefits.
    • Biodegradable Satellites: Designing satellites with biodegradable materials that disintegrate upon re-entry could help prevent long-term debris accumulation. However, these materials currently lack durability for space conditions and face high development costs.
    • Autonomous Debris Removal (ADR): Technologies like robotic arms and laser systems show promise for cleaning up orbital debris but require significant investment and legal clarity before implementation.
    • Global Traffic Monitoring System: Establishing a real-time monitoring system for satellites and debris could reduce collision risks and optimize orbital use. However, data-sharing concerns due to security and commercial interests hinder its development.

    Way forward: 

    • Establish Binding International Frameworks: Governments should collaborate through COPUOS and other international platforms to create enforceable regulations for emissions, debris mitigation, and sustainable practices in space exploration.
    • Promote Innovation Through Incentives: Public and private entities should prioritize funding for green technologies, such as cleaner fuels, biodegradable satellites, and debris removal systems. Financial incentives like subsidies, tax benefits, or penalties can accelerate the adoption of sustainable practices in the space sector.

  • Emissions Gap Report 2024

    Type:
    Subjects: ,
    GS Papers: ,
    Distribution: ,

    Why in the News?

    According to the recently released ‘Emission Gap Report 2024’ presented by UNEP, Global Greenhouse Gas (GHG) emissions have reached a new high of 57.1 billion tonnes of CO2 equivalent in 2023, a 1.3% rise compared to 2022.

    What are the key points of Emissions Gap Report 2024?

    • Urgent Emission Reduction Targets: To align with the 1.5°C goal of the Paris Agreement, global greenhouse gas emissions must decrease by 42% by 2030 and 57% by 2035 compared to 2019 levels.
      • For a 2°C target, reductions of 28% by 2030 and 37% by 2035 are necessary. Current commitments and policies are insufficient, putting the world on track for a temperature rise of 2.6-3.1°C, which would lead to severe climate impacts.
    • Potential for Significant Reductions: The report highlights that it is still technically feasible to achieve the 1.5°C pathway through aggressive action, including increased deployment of renewable energy sources like solar and wind, which could contribute 27% of the necessary reductions by 2030 and 38% by 2035.
      • Additionally, actions related to forests could provide around 20% of the potential reductions in both years. A comprehensive approach involving government action, investment in mitigation strategies, and international cooperation is essential to realize these opportunities.

    What are the Global Emission trends?

    • Global greenhouse gas (GHG) emissions have continued to rise, reaching a record high of 57.1 gigatons of carbon dioxide equivalent in 2023. This marks an increase from previous years, with fossil fuel CO₂ emissions projected at 37.4 billion tonnes, up 0.8% from 2023, and total CO₂ emissions—including land-use changes—projected to be 41.6 billion tonnes in 2024.
    • The increase is attributed primarily to rising emissions from major economies such as China and India, with India experiencing the largest relative increase at 6.1% and China contributing the most in absolute terms.
    • The overall trend indicates that despite some positive developments in renewable energy adoption, there is no sign that global fossil fuel emissions have peaked, necessitating immediate and substantial reductions to meet climate targets.

     

    What is the progress of G20 countries towards NDCs?

    • Mixed Progress on NDCs: Among G20 countries, six members (China, India, Indonesia, Japan, Russia, and Turkey) are projected to meet their unconditional Nationally Determined Contribution (NDC) targets with current policies.
      • However, eight members (Argentina, Australia, Canada, the EU, South Korea, South Africa, and the United States) require further action to achieve their targets.
      • This indicates a significant disparity in progress across different G20 nations, with many needing to be on track to meet their commitments under the Paris Agreement.
    • Need for Enhanced Ambition: The G20 must significantly ramp up its climate ambitions in the next round of NDCs to align with the goals of limiting global warming to 1.5°C. This includes committing to substantial emissions reductions—42% by 2030 and 57% by 2035.

    What is the NCD target? 

    • Collective Emission Reduction Goals: G20 countries have pledged to reduce greenhouse gas emissions through Nationally Determined Contributions (NDCs), targeting a 42% reduction by 2030 and 57% by 2035, aligned with the Paris Agreement to limit warming below 2°C.
    • Diverse Member Targets and Progress: G20 members have varied NDC targets, such as China aiming to peak CO2 emissions by 2030 with a 60-65% reduction in carbon intensity, while Argentina caps net emissions at 483 million tons of CO2 equivalent.

    What is needed to bridge the gap between 2030 and 2035 goals? (Way forward)

    • Significant Annual Emission Reductions: A reduction of 7.5% per year until 2035 is necessary to align with the 1.5°C pathway, while a 4% annual reduction is needed for the 2°C target.
    • Investment in Renewable Energy: The increased deployment of solar and wind technologies could deliver approximately 27% of the total emission reduction potential by 2030 and 38% by 2035.
    • Action on Forests: Protecting and restoring forests could provide around 20% of the required reductions in both years.
    • Comprehensive Policy Measures: A whole-of-government approach is essential, maximizing socioeconomic and environmental co-benefits while minimizing trade-offs.
    • Increased Mitigation Investment: A minimum six-fold increase in investments for climate mitigation is critical, necessitating reforms in global financial systems and strong private sector involvement.

    The recent UN Climate Change Conference (COP29) held in Baku, Azerbaijan, concluded with significant yet contentious outcomes, particularly regarding the New Collective Quantified Goal (NCQG) for climate finance. This editorial reflects on the implications of the NCQG and the broader context of climate negotiations.

    This editorial content can be used to present the significance of ‘Climate finance for developping countries’ and the challenges associated at Global stage.

    _

    Let’s learn!

    Why in the News?

    COP29 dubbed the “Finance COP,” was expected to deliver an ambitious outcome on the NCQG (New Collective Quantified Goal on Climate Finance). However, it fell short by neglecting equitable burden-sharing and climate justice, overlooking the financial needs of the Global South.

    Why do the Developing countries need Finance for climate change? 

    • Upfront Costs of Clean Technologies: Renewable energy technologies often have high upfront costs, which require government support to make them affordable to consumers, especially in developing countries.
    • Long-term Benefits but High Initial Investment: While renewable technologies have lower long-term operational and fuel costs, the high initial investment remains a significant barrier.
    • Financial Gaps and Urgency: Developing countries need urgent upscaling of finance to meet transformational goals. The pressure on government resources is compounded by the need for fiscal prioritization toward development activities.
    • Debt Issues and Risk: High debt burdens in developing countries prevent them from accessing affordable capital, making it difficult to incentivize private investment in green technologies.
    • High Cost of Capital: Developing countries face much higher lending rates, limiting their ability to access financial markets at favourable rates for climate action.
    • International Support Needed: Finance from developed countries, particularly in the form of public grants instead of loans, is essential to support the transition to green energy in developing nations.

    What are the roles of the NCQG (New Collective Quantified Goal on Climate Finance)?

    • Origins and Rationale: The NCQG was designed to address the shortcomings of previous climate finance pledges, including the $100 billion annual commitment made at Cancun in 2010. The NCQG aims to establish clearer, more accountable climate finance goals.
      • NCQG aims to establish a new financial target post-2025 to support developing countries, succeeding the $100 billion annual commitment from developed nations.
    • Addressing Climate Finance Gaps: NCQG seeks to bridge climate finance gaps by ensuring both the quantity and quality of financial instruments meet developing nations’ needs.
      • By setting a collective goal, NCQG promotes trust and cooperation among nations to effectively implement the Paris Agreement.
    • Catalyzing Private Investment: NCQG encourages private sector investment by signalling stability and commitment to climate finance.
    • Supporting Climate Resilience: The goal help developing countries adapt to climate impacts and transition to low-carbon economies with necessary funding.
    • Upholding Principles of Equity: NCQG is grounded in Common but Differentiated Responsibilities (CBDR), ensuring tailored support for developing countries based on their specific needs and capacities.

    What are the challenges?

    • Financial Needs of Developing Countries: The UNFCCC’s Second Needs Determination Report estimated that $5 trillion to $7 trillion would be required by 2030 to meet the needs of 98 developing countries. Developing nations have requested $1.3 trillion annually by 2030.
    • Disappointing Outcome at COP29: Developed countries agreed to a $300 billion annual commitment by 2035, which is seen as insufficient compared to the needs of the developing world. This amount does not represent a significant shift in financial flows and falls short of transformative action.
    • Lack of Commitment to Climate Justice: The NCQG falls short in terms of equitable burden-sharing, failing to adequately recognize the financial needs of the global south and climate justice.

    Way forward: 

    • Increase Financial Commitments: Developed countries must significantly enhance their financial commitments, moving beyond the $300 billion annually agreed at COP29, and align with the $1.3 trillion requested by developing nations to meet urgent climate goals.
    • Ensure Equitable Burden-Sharing: Future climate finance discussions must prioritize climate justice, adhering to the principles of Common but Differentiated Responsibilities and Respective Capabilities (CBDR-RC), ensuring that developed countries take on a larger share of the financial burden.
    • Focus on Grants over Loans: Developed countries should provide more finance in the form of public grants rather than loans, addressing the debt burdens of developing countries and enabling them to invest in green technologies without further exacerbating fiscal constraints.

    Land degradation is defined by the United Nations Convention to Combat Desertification (UNCCD) as the “reduction or loss of the biological or economic productivity and complexity of rainfed cropland, irrigated cropland, or range, pasture, forest and woodlands” due to various pressures, including land use and management practices. This phenomenon results in diminished soil quality and productivity, affecting both ecosystems and human livelihoods.

    Why is it a Matter of Concern?

    Land degradation poses significant risks to both humans and ecosystems:

    • Water Insecurity: Land degradation exacerbates water scarcity and reduces access to safe water, leading to a higher incidence of water- and food-borne diseases.
      • The World Health Organization (WHO) reports that unsafe drinking water and inadequate sanitation lead to approximately 829,000 deaths per year from diarrheal diseases alone.
    • Food Security: It reduces the quality and quantity of food production, increasing malnutrition risks.
    • Health Risks: Degraded lands contribute to the spread of water- and food-borne diseases due to poor hygiene and lack of clean water. Respiratory issues can arise from soil erosion and dust.
    • Environmental Impact: Eroded soil carries fertilizers and pesticides into water bodies, harming aquatic life and communities dependent on these resources.
    • Climate Change: Healthy soils act as carbon sinks. Degradation leads to the release of stored carbon and nitrous oxide, exacerbating global warming. The report indicates that land ecosystems’ capacity to absorb human-caused carbon dioxide has decreased by 20% over the last decade.

    What is Causing Land Degradation?

    • Chemical Overuse: Excessive fertilisers and pesticides degrade soil; 50% of agricultural land suffers from nutrient depletion, salinisation, and waterlogging affecting 30% of irrigated lands globally.
    • Soil Erosion: Unsustainable farming practices lead to the loss of 24 billion tons of fertile soil annually, reducing crop yields by up to 50% in some regions.
    • Climate Change: Extreme weather events reduce global crop yields by 10%-50% by 2050; 12.6% of drylands were degraded between 1982-2015, affecting 213 million people.
    • Urbanization: Rapid urban growth of 1 million hectares per year destroys habitats, reduces farmland, and increases runoff, exacerbating soil erosion and biodiversity loss.
    • Deforestation and Overgrazing: 420 million hectares of forest lost since 1990; overgrazing degrades 34% of the global degraded area, weakening soil health and ecosystems.

    Which Areas are the Worst Affected?

    • Dry Regions: Areas such as South Asia, northern China, California (USA), and the Mediterranean are particularly vulnerable.
    • Global Context: Approximately 15 million square kilometers of land are already degraded an area larger than Antarctica with an additional million square kilometers degrading each year. A third of humanity lives in drylands, which encompass three-quarters of Africa.

    Way forward: 

    • Sustainable Land Management Practices: Promote eco-friendly agricultural methods, reforestation, and efficient irrigation to restore soil health, combat erosion, and improve water retention in degraded lands.
    • Global Collaboration and Policy Implementation: Strengthen international frameworks like the UNCCD, allocate resources for affected regions, and adopt policies that integrate land restoration with climate resilience and biodiversity conservation.
