  • The shape of a five-year climate agenda for India

    Why in the news? 

    The new government’s climate actions will impact all sectors, shaping India’s sustainable economic path, global leadership, and fight for climate finance and justice.

    Initiatives Taken by the Indian Government in the Last Decade and Their Significant Results

    • International Solar Alliance (ISA): Promotes the widespread adoption of solar energy, enhancing global cooperation in renewable energy.
    • Coalition for Disaster Resilient Infrastructure (CDRI): Focuses on building resilient infrastructure to withstand climate-induced disasters.
    •  Net-Zero by 2070: India’s commitment to achieve net-zero emissions by 2070 marks a significant shift towards absolute emission reductions.
    • Enhanced Nationally Determined Contributions (NDCs): Setting ambitious targets for reducing emissions intensity and increasing renewable energy capacity.
    • Indian Emissions Carbon Trading Scheme: Establishing a carbon trading system to incentivize emission reductions and support sustainable economic growth.
    • Significant Growth in Renewable Energy Capacity: Rapid expansion in solar and wind energy installations, contributing to India’s international non-fossil fuel energy targets.
    • Green Development Pact under G-20 Presidency: Integrating green development principles into global economic practices, showcasing India’s leadership in sustainable development.

    How India can enhance it’s Global negotiations wrt Climate change? 

    • Hosting International Climate Summits: India should aim to host a major international climate summit like the United Nations Conference of Parties (COP) in 2028. This would provide a platform to showcase its climate leadership and set ambitious global climate agendas. Successful hosting, akin to its G-20 Presidency, would strengthen India’s influence in global climate policy.
    • Advocacy and Consensus Building: India should start early to build consensus on critical climate issues, such as ending new investments in oil and gas post-2030 and securing significant commitments for adaptation finance. Proactively engaging in dialogues, forming alliances, and addressing concerns of other nations will help India lead negotiations and drive meaningful outcomes.
    • Promoting Equity and Climate Finance: India should continue to emphasize equity in climate action and finance in international forums. Advocating for fair treatment of developing countries and pushing for enhanced climate finance mechanisms will strengthen India’s position as a leader of the Global South.

    Role of Federal Entities in Enhancing Climate Action

    • Collaboration on Long-Term Climate Strategies: Federal entities can work with state governments to develop and implement long-term climate and energy models. Examples include supporting states like Tamil Nadu and Bihar in crafting their net-zero plans.
    • Enhanced Coordination and Policy Alignment: Forming a Centre-State coordination group can ensure better synchronization of climate actions across states. This group can facilitate regular communication and policy alignment while respecting the autonomy of each state.
    • Financial Incentives through the Sixteenth Finance Commission: Federal entities can use financial mechanisms like the Finance Commission to incentivize states for their climate initiatives. This can include grants or additional funding for states that demonstrate significant progress in climate action.
    • Integration of Scientific Capabilities in Policymaking: Encouraging states to incorporate scientific modelling and data analysis into their climate policies. Federal support can enhance the technical capabilities of states, ensuring data-driven and effective climate strategies.
    • Consistent and Accurate Climate Data Management: Developing a unified MRV architecture at the state level to standardize data collection and reporting. This system can help track progress, ensure accountability, and facilitate better policy adjustments based on reliable data.

    The Indian government has taken several initiatives to address climate change, but their effectiveness is still being evaluated:

    • National Action Plan on Climate Change (NAPCC): Launched in 2008, the NAPCC identified eight national missions to promote understanding of climate change, adaptation and mitigation, energy efficiency, and natural resource conservation. While these missions have led to some progress, such as the ambitious targets set under the National Solar Mission, their overall impact is still being assessed.
    • State Action Plans on Climate Change (SAPCCs): Under the NAPCC, states are required to develop their own action plans. As of 2022, 33 states and union territories have prepared their SAPCCs. However, the implementation and monitoring of these plans remain a challenge.
    • Climate change research and knowledge networks: The government has supported various research initiatives and knowledge networks to enhance understanding of climate change impacts and responses. These include the National Network Programmes on Climate Change Modelling, Aerosols, and Coastal Vulnerability. While these networks have generated valuable knowledge, their ability to inform policy and action is still being evaluated

    Conclusion: India should expand its climate targets beyond the power sector to include other key areas such as transportation, industry, and agriculture. Clear and ambitious targets for zero-carbon two- and four-wheelers, as well as other sectors, will drive comprehensive decarbonization efforts.

  • [pib] Metal Oxide Nano-composite developed for Environmental Clean-up

    Why in the News?

     A new metal oxide nanocomposite has been developed by The Institute of Advanced Study in Science and Technology (IASST)  that can help photocatalytic degradation of organic pollutants like dyes and pharmaceuticals and hence can be used as sustainable technologies for cleaning up the environment.

    Understanding Photocatalysis and Metal Oxides

    • Photocatalysis is a process that uses light to accelerate chemical reactions, particularly useful for degrading harmful substances in water and air.
    • They facilitate this reaction without being consumed.
    • Examples: Titanium Dioxide (TiO2), Zinc Oxide (ZnO)  and Tungsten Trioxide (WO3)

    How do they work?

    • When exposed to light, these metal oxides generate electron-hole pairs.
    • These pairs are highly reactive and can break down pollutants into harmless by-products.
      • Work Efficiency: The overall efficiency of this process depends on several factors, including the choice of metal oxide, its crystal structure, light intensity, pollutant concentration, pH level, and the amount of catalyst used.
      • Optimisation: Optimizing these factors is crucial for maximising the degradation rates of pollutants. Adjustments in the type of metal oxide, light parameters, and other conditions can significantly enhance the photocatalytic efficiency.

    Breakthrough by IASST: NiTF Composite

    • The team developed a nanocomposite called NiTF, which stands for Nickel-doped Titanium Dioxide on Fuller’s Earth. 
    • This innovative material combines the photocatalytic properties of titanium dioxide with the adsorption capabilities of Fuller’s earth, a type of natural clay.

    What is Fuller Earth?

    • Fuller’s earth is a term for various clays used as an absorbent, filter, or bleaching agent.
    • Products labeled fuller’s earth typically consist of palygorskite or bentonite.
    • Primary modern uses include as absorbents for oil, grease, and animal waste, and as a carrier for pesticides and fertilizers

    Testing and Results

    • The NiTF nanocomposite was tested for its ability to decolorize methylene blue, a common dye.
      • Methylene blue is a persistent pollutant toxic to aquatic life, harmful to human health, and causes colour pollution in water bodies.
    • The results were impressive, with the composite achieving a 96.15% decolorization of the dye solution at a pH of 9.0 under visible light within 90 minutes.
    • Fuller’s earth enhanced the TiO2’s ability to adsorb pollutants, even in the absence of light.
    • This suggests that the NiTF nanocomposite could be a cost-effective solution for environmental photocatalysis, providing benefits even in low-light conditions.

    Potential Applications

    • Catalysis: The nanocomposite can enhance the efficiency of various chemical reactions.
    • Energy Storage: It has the potential to improve systems for storing energy.
    • Sensors: The material can be used to develop highly sensitive detection devices.
    • Optoelectronics: The nanocomposite can advance technologies that use light for electronic devices.
    • Biomedical Fields: It can be applied in medical treatments and diagnostics.
    • Coatings: The material can be used to create protective and functional surfaces.
    • Renewable Energy: It can facilitate water splitting to produce renewable energy.

  • Worlds Oldest Prehistoric Ostrich Nest discovered in Andhra 

    ostrich
    PC: India Today

    Why in the News?

    Archaeologists have discovered a 41,000-year-old ostrich nest in Prakasam, Andhra Pradesh.

    Prehistoric Ostrich Nest: Details of the Discovery

    • The nest, identified as the world’s oldest known ostrich nest, measures 9-10 feet in width.
    • The nest was once home to 9-11 eggs but was capable of holding 30-40 eggs at a time.
    • Ostriches are mega omnivores, weighing between 90 and 140 kg and standing seven to nine feet tall.

    What are Megafauna?

    • Megafauna generally refers to animals weighing more than 50 kg, though scientific definitions vary.
    • The term was first used by Alfred Russel Wallace in his 1876 book, “The Geographical Distribution of Animals.”
    • Megafauna can be classified into:
      • Megaherbivores (plant-eaters),
      • Megacarnivores (meat-eaters), and
      • Megaomnivores (who eat both plants and meat).

    Historical Evidence of Megafauna

    • Early Documentation: Richard Lydekker in 1884 presented the earliest documented evidence of ostriches in the subcontinent, identifying the extinct Struthio asiaticus in the Dhok Pathan deposits in Upper Siwalik Hills, present-day Pakistan.
    • Discoveries in Maharashtra: Archaeologist S A Sali in 1989 reported ostrich eggshell beads and engraved pieces dating back to 50,000–40,000 years ago at Patne, Maharashtra.
    • CCMB Research in 2017: Researchers at the Centre for Cellular and Molecular Biology (CCMB) in Hyderabad established the presence of ostriches in Rajasthan, Madhya Pradesh, and Gujarat 25,000 years ago.

    Broader Implications and Studies

    • Biogeographical Dispersion: The presence of ostriches in India is attributed to bio-geographical dispersion from the continental drifting of Gondwanaland.
    • Late Quaternary Extinctions: The study, titled ‘Late Quaternary extinctions in the Indian Subcontinent,’ established that the disappearance of large animals began around 30,000 years ago, coinciding with the arrival of humans.
    • Co-Evolution Hypothesis: The study supports the hypothesis that fauna and their resilience to extinction resulted from coevolution with hominins, with geographic isolation and abiotic factors accelerating extinction.

    PYQ:

    [2018] The term “sixth mass extinction/sixth extinction” is often mentioned in the news in the context of the discussion of:

    (a) Widespread monoculture practices in agriculture and large-scale commercial farming with indiscriminate use of chemicals in many parts of the world that may result in the loss of good native ecosystems.

    (b) Fears of a possible collision of a meteorite with the Earth in the near future in the manner it happened 65 million years ago that caused the mass extinction of many species including those of dinosaurs.

    (c) Large-scale cultivation of genetically modified crops in many parts of the world and promoting their cultivation in other parts of the world which may cause the disappearance of good native crop plants and the loss of food biodiversity.

    (d) Mankind’s over-exploitation/misuse of natural resources, fragmentation/loss of natural habitats, destruction of ecosystems, pollution and global climate change.

    Mentor comments: The Supreme Court in M K Ranjitsinh & Ors. v. Union of India & Ors. ruled that people have a right to be free from the adverse effects of climate change which should be recognised by Article 14 and Article 21 of the Constitution. The ruling of the Supreme Court was rendered in response to a writ brought by a government official. The court acknowledged the complex interplay between environmental conservation, social equity, economic prosperity, and climate change. It stressed the need to balance the conservation of endangered species like the Great Indian Bustard (GIB) with the imperative of protecting against climate change.

    It appointed an Expert Committee to determine the best way to protect the species. This decision aimed to support India’s renewable energy goals and climate commitments while ensuring environmental protection. However, the effectiveness of court rulings on climate change remains a question, as climate change is a complex, multi-dimensional problem that requires a holistic approach. The court’s decision to defer to the executive on certain matters related to climate change policy has also been criticized by some experts.

    Why in the News?

    The Apex court’s recent decision on M K Ranjitsinh & Ors. v. Union of India & Ors. to defer to the executive on certain matters related to climate change policy has been questioned by experts.

    What was the Supreme Court’s recent Landmark Judgment?

    • The Supreme Court in M K Ranjitsinh & Ors. v. Union of India & Ors. ruled that that people have a right to be free from the adverse effects of climate change which should be recognised by Article 14 and Article 21 of the Constitution. 
    • The ruling of the Supreme Court was rendered in response to a writ brought by conservationist and retired government official M K Rnajitsinh, who sought protection for two endangered species namely the Lessor Florican and the Great Indian Bustard.
    • The court acknowledged the complex interplay between environmental conservation, social equity, economic prosperity, and climate change.
    • While modifying its earlier order to underground power cables in the Great Indian Bustard’s habitat, the court prioritized transmission infrastructure to enable renewable energy development to address climate change.

    Present challenges along the verdict of Supreme Court:

    • Unresolved questions: The judgment leaves unresolved questions regarding the court’s emphasis on large-scale clean energy as the main pathway to avoiding climate harm and its potential understatement of climate adaptation and local environmental resilience.
    • Non-clarity: The court did not clarify how the newly recognized right against the adverse effects of climate change will be protected in practice.
    • Two potential approaches to realizing this right emerge:
      • The proliferation of court-based climate litigation, which may lead to an incomplete patchwork of protections.
      • The enactment of climate legislation, which can provide an overarching framework to guide future policy.

    The Need for Climate Legislation in India

    • Absence of an “umbrella legislation” in India : India needs climate legislation that is tailored to its unique context, rather than blindly copying other countries.
    • Framework climate legislation can set the vision for engaging with climate change across sectors and regions, create necessary institutions, and put in place processes for structured and deliberative governance in anticipation of and reaction to climate change.
    • Tailoring Climate Legislation to the Indian Context should also:
      • create a supportive regulatory environment for sustainable cities, buildings, and transport
      • enable adaptation measures like heat action plans and climate-resilient agriculture
      • protect key ecosystems like mangroves
      • consider social equity in achieving these goals
    • A single, omnibus law covering all these areas may not be feasible given India’s existing legal framework.
    Lessons from International Experience:

    • Climate laws in many countries, like the UK’s, focus narrowly on regulating carbon emissions, which is ill-suited for India.
    • Instead, India needs an “enabling law” that stimulates development-focused decisions across sectors towards low-carbon and climate-resilient growth.
    • An enabling law should be more procedurally-oriented, creating institutions, processes, and standards for mainstreaming climate change across ministries and society (emphasizing both adaptation and mitigation).

    Federal Factor:

    • On Decentralized approach: Many areas relevant to climate action, such as urban policy, agriculture, water, and electricity, fall under the authority of state and local level governments. An Indian climate law must set a framework for coherent national action and decentralize sufficiently to empower states and local governments.
    • On Fiscal and Governing Policies: The regional states and local governments need to be provided with information and finance to take effective actions. This would enable diverse segments of society to bring their knowledge and expertise to the table in addressing climate change.

    The Way Forward:

    • India should learn from international experience, both in terms of what not to do and what directions to follow.
    • The country’s climate legislation should be tailored to its unique context of being a developing, highly vulnerable nation still building its infrastructure.

  • Climate change forces Panama islanders to relocate

    Why in the news? 

    In early June, approximately 300 families were relocated from the island of Gardi Sugdub in Panama’s Guna Yala province due to concerns about rising sea levels.

    What is happening in Gardi Sugdub?

    • Location and Community: Gardi Sugdub, home to about 1,300 members of the Guna community, is an island in Panama’s Guna Yala province.
    • Sea Level Rise: The Caribbean region, where Panama is situated, is experiencing sea level rise at an average rate of 3 to 4 millimetres per year. This rate is expected to accelerate to 1 centimetre per year or more by 2100.
    • Flooding: Annually, particularly in November and December, seawater floods houses and streets on Gardi Sugdub, despite efforts to fortify the island.
    • Relocation: The Panamanian government constructed 300 new houses on the mainland in a development called Nuevo Cartí to relocate affected families.

    How are other island nations affected by sea level rise?

    • Small island developing states (SIDS) are particularly vulnerable due to their low elevation and reliance on marine resources. SIDS in the Caribbean, Pacific, Atlantic, Indian Ocean, and South China Sea face existential threats from rising sea levels.
    • Examples of Impact: Islands such as Tuvalu, the Marshall Islands, and Kiribati are experiencing significant land loss and threats to their culture and economies.
    • Consequences: Coastal erosion, salinization of freshwater resources, and increased vulnerability to extreme weather events due to rising sea levels, storm surges, and ‘king tides.’

    How fast is the global sea level rising?

    • Since 1880, global sea levels have risen by approximately 21–24 centimeters. The rate of increase has accelerated in recent decades.
    • Causes: The primary drivers are global warming, thermal expansion of seawater, and the melting of land-based ice such as glaciers and ice sheets.
    • Due to the Global Temperature Increase: The global average temperature has increased by at least 1.1 degrees Celsius since 1880, contributing to rising sea levels.

    Way forward: 

    • Strengthen Coastal and Environmental Defenses: Construct seawalls, breakwaters, and other barriers to protect against storm surges and coastal erosion. Restore and preserve natural coastal barriers such as mangroves, coral reefs, and wetlands to enhance natural protection.
    • Develop and Implement Climate Adaptation Strategies: Create comprehensive climate adaptation plans that include relocation strategies for vulnerable communities.
