Subject: Environment

  • A turf war with the wild

    Why in the news?

    • Instances of human-animal conflict are on the rise in Kerala with the summer heat, scarcity of food, and loss of habitat forcing wild animals to stray into human habitations for sustenance.

    Context-

    • Vulnerability of tribal communities living in such areas. While they have intricate knowledge of the forest and its resources, they lack the protective measures and resources available to more urbanized populations, leaving them more susceptible to the dangers of wildlife encounters.

    Human-animal conflict in Kerala-

    • Surge in Incidents: Kerala has experienced a significant increase in human-animal conflict incidents across its districts, attributed to the state’s significant forest cover and densely populated settlements near wildlife habitats.
    • Human Casualties: Human-wildlife conflicts have resulted in a substantial loss of human lives, with 93 reported deaths in 2023-24. The previous year recorded 98 human casualties.
    • Hotspot District: Wayanad stands out as a hotspot for human-animal conflicts, with 69 reported deaths between 2011 and 2024. Incidents involve encounters with wild elephants and, in one case, a tiger attack.
    • Diverse Wildlife Involved: Human-animal conflicts in Kerala involve various species, including elephants, tigers, leopards, bears, wild gaurs, wild boars, and monkeys. This diversity underscores the complexity of managing conflicts across different ecosystems and habitats.
    • Impact on Livelihoods: The conflicts have severe repercussions on people’s livelihoods, particularly those dependent on agriculture and farming. Attacks by wild animals prevent farmers from cultivating their land, leading to economic hardship and food insecurity.
    • Vulnerable Communities: Vulnerable communities like tribal groups and small-scale farmers are disproportionately affected by human-animal conflicts. Limited resources and infrastructure exacerbate their vulnerability to wildlife attacks, as seen in the case of Abraham Palatt and his family.

    Steps taken by Government to deal these issues – 

    • State-Specific Disaster: The Kerala government declared human-animal conflict as a state-specific disaster in March, becoming the first state to do so. This decision signifies the severity and urgency of addressing the issue.
    • Responsibility Shift: Management of human-animal conflicts now falls under the purview of the Kerala State Disaster Management Authority (KSDMA), with a committee headed by the Chief Minister established for this purpose.
    • Community Involvement: The government plans to involve local communities through neighborhood groups to enhance surveillance on forest fringes. These groups will collaborate with government agencies and elected representatives to disseminate alerts about wildlife presence.
    • Recruitment and Equipment: The government aims to strengthen surveillance by recruiting more forest watchers and establishing rapid response teams equipped with firearms, surveillance devices, drones, tranquilizing guns, and advance warning systems.
    • Inter-State Collaboration: An inter-State coordination committee involving the Forest departments of Karnataka, Kerala, and Tamil Nadu has been formed to address human-wildlife conflicts collectively. This initiative aims to share intelligence and resources to mitigate conflicts, particularly along interstate borders.

    Measures to address human-wildlife conflict-

    • Forest Quality Improvement: Improving the quality of forests through measures such as reducing fragmentation and patchiness can help create healthier ecosystems that support a more balanced coexistence between humans and wildlife.
    • Conservation Mission with Tribal Communities: Involving tribal communities in conservation efforts ensures their participation and traditional knowledge is valued. Collaborative conservation initiatives can promote sustainable practices and protect both biodiversity and livelihoods.
    • Rejuvenation of Natural Forest Streams: Restoring natural water sources in forests is crucial for wildlife habitat and can help mitigate conflicts by providing essential resources within their natural environment.
    • Removal of Invasive Plants and Replanting Indigenous Species: Removing invasive plant species and replanting indigenous ones can restore ecological balance and support native wildlife populations, reducing their reliance on human-impacted areas.
    • Utilization of MGNREGS: Leveraging government schemes like the Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGS) to support conservation efforts can provide employment opportunities while simultaneously contributing to environmental restoration projects.
    • Awareness Programs on Responsible Tourism: Educating tourists about responsible behavior around wildlife can minimize human-wildlife conflicts caused by human disturbance. This includes emphasizing the importance of maintaining a safe distance and respecting wildlife habitats.
    • Effective Institutional Framework: Establishing a robust institutional framework at various levels of governance, from local to inter-state, is essential for coordinated action in managing human-wildlife conflicts. This involves collaboration between different government departments, wildlife authorities, and local communities.

    Conclusion-

    Human-wildlife conflicts surge in Kerala, endangering lives and livelihoods. Government initiatives, community involvement, and conservation efforts are crucial for mitigating conflicts and fostering coexistence, ensuring a sustainable future for both humans and wildlife.

  • Subduction Zone discovered beneath Gibraltar Strait

    What is the news?

    • Scientists in Portugal have uncovered a concerning revelation about the fate of the Atlantic Ocean, highlighting a potential ‘Ring of Fire’ (a Subduction Zone).
    • Researchers caution that the Atlantic may be on the brink of closure due to subduction activity.

    Why discuss this?

     

    • Closure of Gibraltar Strait: Computer simulations project the subduction zone’s expansion over the next 20 million years, forming the ‘Ring of Fire’ in the Atlantic leading to the closure of Gibraltar Strait.
    • Geological Parallel: This process mirrors the Pacific Ocean’s Ring of Fire, reshaping the ocean basin through gradual subduction of the ocean floor beneath continents.

     

    About Gibraltar Strait

    Details
    Location
    • Connects the Atlantic Ocean to the Mediterranean Sea;
    • Separating the southern tip of the Iberian Peninsula of Europe from the northern coast of Africa.
    Width Approximately 13 km (8.1 miles) at its narrowest point.
    Depth Varies, with the deepest point reaching around 300 meters (984 feet).
    Formation
    • Convergence point for the Eurasian Plate and the African Plate.
    • Formed around 5.33 million years ago during the Messinian salinity crisis when the Atlantic Ocean breached the barrier separating it from the Mediterranean Sea, resulting in a catastrophic flood known as the Zanclean flood.
    • The strait’s current shape and depth were further influenced by tectonic movements and erosional processes over geological time.
    Historical Significance Serves as a key maritime passage for trade and military purposes.
    Disputes
    • Subject of contention between Spain and the United Kingdom;
    • Gibraltar Overseas Territory under British control.

     

    What are Subduction Zones?

    • Subduction zones occur at convergent plate boundaries, where two tectonic plates move toward each other.
    • This convergence is often between an oceanic plate and a continental plate or between two oceanic plates.
    • Subduction Process:
    1. Collision of Tectonic Plates: When two tectonic plates collide, the denser oceanic plate is forced beneath the less dense continental plate or another oceanic plate.
    2. Partial Melting: As the oceanic plate descends into the mantle, it generates intense heat and pressure, causing partial melting of the mantle material.
    3. Volcanic Activity: The molten material formed by the subduction process rises through the Earth’s crust, leading to volcanic eruptions at the surface.
    4. Formation of Volcanic Arcs: These eruptions often occur in chains known as volcanic arcs, which parallel the subduction zone. Ex. Andes in S. America; Cascade Range in North America.

    Implications of this Activity

    • Earthquakes: Subduction zone earthquakes can be particularly destructive and may trigger tsunamis due to the displacement of large volumes of water.
    • Trench Formation: The surface expression of a subduction zone is often a deep oceanic trench, where the descending plate bends and plunges into the mantle.
    • Mountain Building: Over time, the continuous subduction of oceanic crust can lead to the uplift and deformation of the overriding plate, resulting in the formation of mountain ranges adjacent to the subduction zone. These mountains may exhibit complex geological structures, including folds and faults.
    • Recycling of Oceanic Crust: As oceanic plates are subducted, they are gradually consumed by the mantle, releasing minerals and elements that are eventually returned to the surface through volcanic activity.

  • Forest Fires in the Nilgiris

    Why in the news?

    Forest fires have been ongoing in the Coonoor forest range of the Nilgiris in Tamil Nadu for the past week.

    Context:

    • The Indian Air Force has recently joined the firefighting operations led by the state forest department.
      • A Mi-17 V5 helicopter has been deployed to conduct numerous Bambi Bucket operations, delivering approximately 16,000 liters of water to extinguish the fires.

    What are Forest Fires/Wildfires?

    Forest fires, also known as wildfires, are uncontrolled fires that occur in forests, grasslands, or other wild areas. These fires can spread rapidly, fueled by dry vegetation, high temperatures, low humidity, and strong winds.

    There are three types of Forest Fires:

    • Surface Fires: These fires burn along the forest floor, consuming vegetation and leaf litter. Surface fires are typically less intense and move relatively slowly compared to other types of wildfires. They are often caused by natural factors like lightning strikes or human activities such as campfires.
    • Ground Fires: Ground fires occur beneath the surface of the forest floor, burning through layers of organic matter like peat and roots. These fires can smolder for extended periods, producing significant heat and damage to the soil. Ground fires are often difficult to detect and extinguish, posing a long-term threat to forest ecosystems.
    • Crown Fires: Crown fires are the most severe type of wildfire, burning through the upper canopy of trees. These fires spread rapidly, driven by strong winds and dry conditions, and can cause extensive damage to forested areas. Crown fires are challenging to control and extinguish, posing significant risks to both property and lives.

    What is the frequency of Forest Fires in India?

    • Period of Fires in India– 
        • April-May are usually the worst fire months across the country.
        • June to November is considered to be forest fire season in India, with hundreds of thousands of small and large fires burning every year.
    • Affected areas in India- 
        • According to the 2019 India State of Forest Report (ISFR) published by the Forest Survey of India (FSI) under the Ministry of Environment, Forest and Climate Change, over 36% of India’s forest cover was susceptible to frequent fires.
        • Approximately 4% of the forest cover was categorized as extremely prone to fire, while an additional 6% was classified as very highly fire-prone.
    • Most Forest Fire Regions-
      • As per the FSI, dry deciduous forests are more susceptible to severe fires, whereas evergreen, semi-evergreen, and montane temperate forests exhibit lower susceptibility to fires.
      • Northeast India, Odisha, Maharashtra, Jharkhand, Chhattisgarh, and Uttarakhand are identified as the regions most susceptible to forest fires
      • During March 2023, extensive bushfires erupted in Goa, prompting an inquiry into their possible human origins.
      • In 2021, a series of forest fires occurred in Uttarakhand, Himachal Pradesh, the Nagaland-Manipur border, Odisha, Madhya Pradesh, and Gujarat, encompassing several wildlife sanctuaries.

    Incidents of Forest Fires in 2024

      • During the past week, Mizoram reported the highest number of forest fires, totaling 3,738, followed by Manipur with 1,702, Assam with 1,652, Meghalaya with 1,252, and Maharashtra with 1,215.
    • Forest fires have been increasing since early March along the:
      • Konkan belt in Maharashtra,
      • South-coastal Gujarat along Gir Somnath and Porbandar,
      • Southern Rajasthan and adjoining south-western districts of Madhya Pradesh,
      • Coastal and interior Odisha, and adjoining Jharkhand.
    • Forest Fires in South India– Certain forest areas in Andhra Pradesh and Telangana are susceptible to fires.
      • However, as per the FSI, forests in southern India, characterized by mainly evergreen or semi-evergreen vegetation, are relatively less prone to fires. Nonetheless, Tamil Nadu has witnessed wildfires in its forests in recent years.

    What are the reasons behind Forest Fires in 2024?

    • Highest Temperature: February 2024 was exceptionally hot over Southern India, the hottest since 1901, with January ranking as the fifth warmest in over a century.
    • Early build-up of heat load: Recorded maximum, minimum, and mean temperatures have remained above normal over the southern states for the past two months, leading to an early build-up of heat load in the region well before the onset of the summer season.
    • Excess Heat Factor (EHF): The IMD has warned of the significantly higher-than-normal prevalence of EHF over western Andhra Pradesh and neighboring Karnataka. EHF predicts the likelihood of a heatwave over a region, with maximum temperatures reaching 40 degrees Celsius, unusual for mid-March.
    • Mild Aridity: In the absence of rain and prevailing high temperatures, the IMD has classified almost all districts of southern India under mild aridity.
    • Climatic Conditions: High aridity, above-normal day temperatures, clear sky conditions, and calm winds during the early phase of the summer season contribute to the spike in forest fire incidents in southern India this year.

    Suggestive measures to address Forest Fires:

    • Prevention: Implementing fire prevention measures such as creating firebreaks, clearing vegetation around vulnerable areas, and enforcing restrictions on activities that can cause fires.
    • Early Detection: Installing and maintaining fire detection systems including lookout towers, satellite monitoring, and automated sensors to detect fires early. And Training and equipping forest rangers and firefighters with the skills and tools needed to identify and report fires promptly.
    • Rapid Response: Establishing communication networks to coordinate response efforts among firefighting agencies, emergency services, and other stakeholders. Strategies Pre-positioning firefighting equipment and resources in strategic locations to facilitate rapid deployment.

    Conclusion: Forest fires, prevalent in India, pose significant threats to ecosystems and communities. Climatic factors exacerbate the situation. Urgent measures including prevention, early detection, and rapid response are essential to mitigate these risks and safeguard our forests.

  • IPEF: India to join US-led Co-operative Program on Carbon Market

    What is the news-

    • India has decided to participate in one of the four cooperative work programmes initiated under the ‘Clean energy pillar’ of the US-led Indo Pacific Economic Framework (IPEF).
    • India will join the cooperative working group on carbon markets, with the Ministry of Power leading the initiative.

    What are Carbon Markets?

     

    • Carbon markets, also known as emissions trading systems or cap-and-trade programs, are market-based mechanisms designed to reduce greenhouse gas emissions.
    • Article 6 of the Paris Agreement (2015) provides for the use of international carbon markets by countries to fulfil their Nationally Determined Contributions.
    • A regulatory authority, typically a government or regional organization, sets an overall limit or cap on the amount of greenhouse gases that can be emitted by covered entities within a specific jurisdiction or sector.
    • Entities get permits for emissions. They can trade these permits with others.
    • Entities must have enough permits to cover their emissions. If they don’t, they buy more.

     What is the Indo-Pacific Economic Framework (IPEF)?

    • It is a US-led initiative that aims to strengthen economic partnerships among participating countries to enhance resilience, sustainability, inclusiveness, economic growth, fairness, and competitiveness in the Indo-Pacific region.
    • The IPEF was launched in 2021 with a dozen initial partners who together represent 40% of the world GDP.
    • The IPEF is NOT a Free Trade Agreement (FTA) but allows members to negotiate the parts they want to.

    Four main “Pillars” of IPEF

     

    1. Trade that will include digital economy and emerging technology, labour commitments, the environment, trade facilitation, transparency and good regulatory practices, and corporate accountability, standards on cross-border data flow and data localisations;
    2. Supply chain resilience to develop “a first-of-its-kind supply chain agreement” that would anticipate and prevent disruptions;
    3. Clean energy and decarbonization will include agreements on “high-ambition commitments” such as renewable energy targets, carbon removal purchasing commitments, energy efficiency standards, and new measures to combat methane emissions; and
    4. Fair Economy Agreement, with commitments to enact and enforce “effective tax, anti-money laundering, anti-bribery schemes in line with [American] values”.

    Members Countries include:

    • Currently, India and 13 countries other located in the Pacific Ocean are its members: Australia, Brunei, Fiji, India, Indonesia, Japan, South Korea, Malaysia, New Zealand, Philippines, Singapore, Thailand, United States, and Vietnam.

    How is IPEF different from other trade deals?

    • No market access or tariff reductions have been outlined in the IPEF, although experts say it can pave the way to trade deals.
    • It’s not a take-it-or-leave-it arrangement, like most multilateral trade deals are.
    • Since the IPEF is not a regular trade pact, the members so far are not obligated by all the four pillars despite being signatories.

    PYQ:

    Q.Regarding “carbon credits”, which one of the following statements is not correct? (2011)

    1. The carbon credit system was ratified in conjunction with the Kyoto Protocol
    2. Carbon credits are awarded to countries or groups that have reduced greenhouse gases below their emission quota
    3. The goal of the carbon credit system is to limit the increase of carbon dioxide emission
    4. Carbon credits are traded at a price fixed from time to time by the United Nations Environment Programme.

    What are Particulate Matters (PM)?

     

    • Particulate matter (PM) consists of a mixture of solid particles and liquid droplets suspended in the air.
    • These particles come from various sources, including vehicle emissions, industrial processes, construction activities, agricultural activities, wildfires, and natural dust.
    • PM can be classified into different size categories based on its aerodynamic diameter.
    • Common size fractions include PM10 (particles with a diameter of 10 micrometres or smaller) and PM2.5 (particles with a diameter of 2.5 micrometers or smaller).
    • PM 2.5 are so small that they can penetrate deep into the respiratory system and enter the bloodstream, posing significant health risks.
    • Long-term exposure to elevated levels of PM2.5 has been linked to reduced lung function, aggravated asthma, and increased risk of heart attacks and strokes.

  • The problem of equity in IPCC reports | Explained

    Why in the news?

    In a study published on March 4, researchers analyzed more than 500 future emissions scenarios the UN Intergovernmental Panel on Climate Change (IPCC) assessed in its latest reports.

    Context-

    • These scenarios relate to mitigation actions like reducing carbon dioxide emissions from burning fossil fuels and increasing carbon sequestration through forestry.
    • It found that across all 556 scenarios, income, energy use, and emissions disparities between developed and developing countries are projected to continue up to 2050.

    What are IPCC assessment reports?

    • The IPCC’s Seventh Assessment Cycle (AR7) includes three Working Group reports covering physical science, climate adaptation, and mitigation action, along with a synthesis report consolidating their findings.
    • Thematic special reports are also issued, all aimed at assessing climate-related scientific literature to provide comprehensive knowledge on climate change.

    How does it assess future scenarios?

    • Modeled Pathways: The IPCC utilizes “modeled pathways” to estimate the measures necessary to limit the warming of the Earth’s surface. These pathways are constructed using Integrated Assessment Models (IAMs), which analyze human and earth systems.
    • Integrated Assessment Models (IAMs): IAMs are sophisticated models that encompass various disciplines, including macroeconomics, energy, vegetation, and earth systems. They provide insights into potential futures of the energy and climate system, as well as economies.
    • Components of IAMs: IAMs include macroeconomic models that forecast GDP growth, energy models that project consumption patterns, vegetation models that assess land-use changes, and earth-system models that predict climate evolution based on physical laws.
    • Policy-Relevant Guidelines: IAMs aim to offer policy-relevant guidance on climate action by integrating insights from diverse disciplines. They help policymakers understand the potential implications of various mitigation strategies and inform decision-making processes.
    • Shortcomings of IAMs: Despite their usefulness, IAMs have limitations. They primarily prioritize least-cost assessments, which may not adequately address equity concerns. For example, the cost of implementing climate mitigation measures varies across countries and regions.
    • Equitable Burden Sharing: Experts suggest that IAMs could be modified to enable countries to equitably share the burden of climate action. This approach could involve wealthier nations undertaking more substantial mitigation efforts, considering their greater capacity to bear the costs.
    • Global Cooperation: Addressing climate change requires global cooperation and equitable distribution of responsibilities. IAMs can play a crucial role in informing international climate negotiations and agreements by providing insights into the potential impacts of different policy scenarios.

    What did the new study find?

    • Projection of Inequities in GDP: The scenarios indicate that per-capita GDP in regions such as Sub-Saharan Africa, South Asia, West Asia, and the rest of Asia will remain below the global average even by 2050. These regions collectively represent 60% of the world’s population.
    • Inequities in Consumption and Energy Use: The study identifies disparities between the Global North and the Global South in terms of consumption of goods and services, as well as energy and fossil fuel consumption.
    • Carbon Sequestration and Mitigation Burden: Developing countries are projected to have higher carbon sequestration from land-based carbon sinks (e.g., forests) and greater deployment of carbon capture and storage (CCS) technologies compared to developed countries. This indicates that poorer countries would bear the burden of both mitigation action and carbon dioxide removal.
    • Disregard for Historical Responsibility: The study highlights that the scenarios disregard the historical responsibility of the Global North in contributing to climate change.
    • Neglect of Future Energy Needs: The scenarios also overlook the future energy requirements of the Global South to achieve development goals, indicating a lack of consideration for the development needs of these regions in the models.

    Why does equity matter?

    • Principles of Equity and Common but Differentiated Responsibilities (CBDR): Enshrined in the UN Framework Convention on Climate Change (UNFCCC), these principles emphasize that climate action should be guided by equity and recognize the differing responsibilities and capabilities of countries.
    • Article 3 of UNFCCC: Article 3 underscores the obligation to protect the climate system for the benefit of present and future generations based on equity and common but differentiated responsibilities. Developed countries are urged to take the lead in combating climate change.
    • Differential Responsibilities: The principles acknowledge that while addressing climate change is a global imperative, developed nations, being wealthier and more technologically advanced, should bear a greater burden of climate action compared to developing nations.
    • Equity Considerations in Climate Action: Researchers argue that mitigation pathways modeled using Integrated Assessment Models (IAMs) often neglect equity considerations. These models may not align with the principle of equity, as they may not prioritize the responsibility of developed regions to accelerate towards net negative emissions and support less developed regions.
    • Contradictory Scenarios: Despite the principles of equity and CBDR, the scenarios projected by IAMs may indicate the opposite, with developed regions not accelerating towards net negative emissions and potentially exacerbating global inequalities in climate action.
    • Need for Redistribution of Carbon Budget: Equity principles imply that developed regions should expedite efforts towards achieving net negative emissions and allocate the remaining carbon budget to less developed regions. However, IAM scenarios may not reflect this redistribution of responsibility.

    To address the equity issues highlighted in IPCC reports, several measures can be suggested: (Way Forward)   

    • Equity-Centered Modeling: Modify Integrated Assessment Models (IAMs) to prioritize equity considerations, ensuring that mitigation pathways promote fair burden-sharing between developed and developing countries.
    • Redistribution of Resources: Advocate for the redistribution of financial resources and technology transfer from developed to developing countries to support their climate mitigation and adaptation efforts.
    • Climate Finance: Increase funding for climate adaptation and mitigation projects in developing countries through mechanisms such as the Green Climate Fund, ensuring that resources are allocated equitably and reach the most vulnerable communities.
    • Technology Transfer: Facilitate the transfer of clean and sustainable technologies to developing countries at affordable rates, enabling them to transition to low-carbon development pathways.
    • Policy Coordination: Strengthen international cooperation and coordination on climate policies to ensure coherence and alignment with equity principles, fostering trust and collaboration among countries.
    • Empowerment of Marginalized Communities: Prioritize the inclusion and empowerment of marginalized communities, including indigenous peoples and women, in climate decision-making processes to ensure their voices are heard and their needs addressed.
    • Public Awareness and Education: Promote public awareness and education on the importance of equity in climate action, fostering a sense of shared responsibility and solidarity across countries and communities.

    Conclusion:

    The study on IPCC’s AR6 scenarios reveals persistent inequities in GDP, consumption, and mitigation burden between developed and developing countries. It underscores the importance of integrating equity considerations into climate action to address historical responsibilities and promote fair burden-sharing.
