  • What share of Global CO2 Emissions comes from Aviation?

    Why in the news?

    Aviation accounts for 2.5% of global CO2 emissions. But it has contributed around 4% to global warming to date

    Year-wise Global Aviation demand, Energy Efficiency, and CO2 emissions

    Global Co2 emissions from aviation 

    The reason behind Aviation accounts for 2.5% of global CO2 emissions:

    • CO2 Emissions: When jet fuel burns, it releases carbon dioxide (CO2) into the atmosphere, much like any other combustion process. CO2 as a greenhouse gas has contributed around 4% to global warming to date.
    • Non-CO2 effects: In addition to CO2, aircraft emissions also include other substances like nitrogen oxides, soot, water vapor, and sulfate aerosols. These substances interact with the atmosphere in various ways and can have different climate impacts. For example:
      • Contrails: These are the visible trails of condensed water vapor and ice crystals that form behind aircraft in certain atmospheric conditions. Contrails can contribute to the formation of cirrus clouds, which can have a warming effect on the climate.
      • Induced cirrus cloud formation: Aircraft can also induce the formation of cirrus clouds through their emissions, further contributing to warming.

    Initiatives taken by the Indian Government:

    • India is a Party to the United Nations Framework Convention on Climate Change (UNFCCC), its Kyoto Protocol (KP) and the Paris Agreement (PA).
    • As a Party to the UNFCCC, India periodically submits its National Communications (NCs) and Biennial Update Reports (BURs) to the UNFCCC which includes national Greenhouse Gas (GHG) inventory.
    • The energy sector contributed 75%, Industrial Process and Product Use 8%, the agriculture sector 14%, and the waste sector contributed 3% of total greenhouse gas emissions in 2016.
    • The Land Use Land-Use Change and Forestry  (LULUCF) sector was the net sink and absorbed about 15% of the carbon dioxide in 2016.

    Way Forward:

    • Transitioning to Alternative Fuels: Invest in Research and Development of sustainable aviation fuels (SAFs), such as biofuels, hydrogen, or synthetic fuels, which emit fewer CO2 emissions compared to conventional jet fuel.
    • Improving Aircraft Efficiency: Encourage the adoption of more fuel-efficient aircraft and technologies, including advanced aerodynamics, lightweight materials, and efficient engines.
    • Implementing Operational Improvements: Enhance air traffic management systems to optimize flight routes, reduce delays, and minimize fuel consumption during taxiing, takeoff, and landing.

    Mains PYQs:

    1. Describe the major outcomes of the 26th session of the Conference of the Parties (COP) to the United Nations Framework Convention on Climate Change (UNFCCC). What are the commitments made by India in this conference? (2021)
    2. Discuss in detail the photochemical smog emphasizing its formation, effects and mitigation. Explain the 1999 Gothenburg protocol. (2022)

  • Jiadhal River and Change of its Course

    Why in the news?

    • Climate Change is disrupting Jiadhal River’s (Dhemaji district, Assam) tranquil flow, leading to unprecedented shifts in its course and causing upheaval for residents.

    About Jiadhal River:

    • It flows through the districts of Darrang, Udalguri, and Baksa in the northeastern state of Assam.
      • It is also known Kumotiya River after flowing from Gogamukh.
    • Origin: From the Hills of Bhutan, flows through the Assam Himalayas before meandering through the plains of Assam. It is formed by the confluence of several smaller streams.
    • Major tributaries: Kolong River and the Daokao River.
    • It eventually joins the Brahmaputra River near the town of Nalbari.
    • It is known as the ‘Sorrow of Dhemaji’ for the heavy damage caused by annual floods and erosion.

    Factors leading to changes in the Jiadhal River’s Course  

    • Erosion: Flowing water gradually wears away the riverbanks and bed, causing the river to meander and change course.
    • Sediment deposition: Accumulation of sediment can create new channels or alter the flow pattern of the river.
    • Human activities: Dams, channelization, urbanization, deforestation, and mining can disrupt natural river processes, leading to changes in flow and morphology.
    • Climate change: Changes in precipitation, temperature, and glacier melt affect river flow patterns and behavior.
    • Tectonic activity: Uplift, subsidence, and faulting influence river topography and drainage patterns, leading to adjustments in course and behavior.

    PYQ:

    [2017] With reference to river Teesta, consider the following statements:

    1. The source of river Teesta is the same as that of Brahmaputra but it flows through Sikkim.

    2. River Rangeet originates in Sikkim and it is a tributary of river Teesta.

    3. River Teesta falls into Bay of Bengal at the border of India and Bangladesh.

    Which of the statements given above is/are correct?

  • Decoding the judgment on Jim Corbett

    Why in the news? 

    In its March ruling, the Supreme Court highlighted the corrupt collaboration between politicians, forest officials, and local contractors that led to the illegal felling of 6,000 trees in the Jim Corbett National Park in Uttarakhand.

    Key points related the judgment

    • Shift from Anthropocentrism to Eco-centrism: The Supreme Court emphasized the need for an eco-centric approach rather than anthropocentrism in ecotourism management.
    • Ban on Tiger Safaris in Core Areas: : The court disagreed with the 2019 guidelines of the National Tiger Conservation Authority (NTCA) permitting tiger safaris on the lines of a zoo in national parks, The court directed the banning of tiger safaris in core areas of national parks, aiming to minimize environmental damage and disturbance to wildlife habitats.
    • Committee Formation for Feasibility Study: A committee was constituted to explore the feasibility of permitting tiger safaris in peripheral areas of national parks across India, indicating a cautious approach towards balancing tourism with conservation goals.

    What the court missed

    Absence of Well-Defined Methodology: The court’s decision to recover the cost of restoration from errant individuals and officers lacks a well-defined methodology, making it challenging to accurately assess the damage done to the green cover of Jim Corbett.

    Suggestive measures 

    • Need for Ecosystem Services-Based Valuation: In light of growing degradation of biodiversity hotspots and support for revenue-generating eco-tourism, there is a need for a valuation method based on ecosystem services, which includes benefits like food, water, and climate regulation.
    • Precedent on Ecosystem Services: The court could have set a precedent by prioritizing ecosystem services over eco-tourism or highlighting the need for a precise law and policy regarding ecosystem services, which play a crucial role in environmental conservation and sustainable development.
    • Reference to International Court of Justice (ICJ) Ruling: The reasoning provided by the International Court of Justice (ICJ) in Costa Rica v. Nicaragua (2018) regarding the compensability of damage to the environment could have been used to better understand methodologies for evaluating environmental damage and loss of ecosystem services

    Conclusion 

    The Supreme Court’s ruling on Jim Corbett underscores a shift towards eco-centric ecotourism management, banning tiger safaris in core areas. However, the absence of a clear restoration methodology and the need for ecosystem services-based valuation remain unaddressed, suggesting room for improvement.

  • The blurry lines between wildlife ‘capture’ and ‘rescue’  

    Why in the news? 

    The human-animal conflict in India is a significant issue, with several lives lost and property damage due to the increasing interactions between humans and wildlife

    Difference between between wildlife ‘capture’ and ‘rescue’

    • Capture:  It refers to the act of taking wild animals into custody, often due to conflicts with humans, such as when an animal poses a threat to human safety or property. This may involve trapping, sedating, or physically restraining the animal. The primary goal of capture is to ensure human safety and prevent further damage. Captured animals may be relocated, rehabilitated, or, in some cases, euthanized, depending on the situation and the animal’s condition.
    • Rescue:  It refers to the act of providing assistance to wild animals in distress, such as those injured, orphaned, or trapped in a dangerous situation. The primary goal of rescue is to help the animal recover and, if possible, return it to the wild. Rescue efforts may involve medical treatment, rehabilitation, and release back into the wild.

    Blurred lines between “rescue” and “capture”

    • Guidelines vs. Reality: Despite government guidelines discouraging capture without considering preventative measures, in practice, animals are often captured hastily rather than adopting non-invasive approaches.
    • Case of Elephant “Rescue”: An elephant was captured under the pretext of rescue from a coffee plantation but was subsequently released 200 km away in an unfamiliar landscape, leading to further complications and ultimately its death.
    • Unintended Consequences: The attempt to “rescue” the elephant resulted in its straying into a neighboring state, highlighting the unintended consequences and potential risks associated with such actions.
    • Case of Leopard “Rescue”: Similarly, a leopard was “rescued” after being sighted in an agricultural field, but it died shortly after for unknown reasons, raising questions about the efficacy and ethics of such operations.

    Issues related to rescue of snakes

    • High Frequency of Interactions: Interactions with snakes are more frequent than with other wild animals, resulting in higher incidences of misguided rescue attempts.
    • Failure to Distinguish Between Actions: There’s a lack of distinction between capture, removal, and rescue when managing conflicts with snakes, leading to poor handling and unnecessary removal from habitats under the guise of rescue operations.
    • Issues with Relocation: Relocated snakes have poor survival prospects and relocation doesn’t effectively resolve conflict, potentially increasing future conflict occurrences.
    • Harmful Effects of “Rescue” Operations: Such operations can cause physical trauma, injuries, and stress to animals, reducing their post-release survival chances.

    Suggestive measures

    • Education and Training: Provide comprehensive training to wildlife rescuers on species-specific rescue techniques and emphasize the importance of non-invasive approaches.
    •  Habitat Restoration: Focus on habitat conservation and restoration to reduce human-snake conflicts and provide natural habitats for snakes.
    • Research and Monitoring: Conduct research to understand snake behavior and ecology better, enabling more informed rescue and relocation decisions.
    • Collaboration: Foster collaboration between wildlife authorities, conservation organizations, and local communities to develop effective strategies for managing human-snake conflicts sustainably.

    Conclusion 

    Enhanced training, habitat restoration, research, and collaboration are vital for navigating the blurry lines between wildlife “capture” and “rescue,” ensuring humane and effective management of human-animal conflicts in India.

    Mains question for practice 

    Q Discuss the blurred lines between wildlife “capture” and “rescue” in India, highlighting issues and proposing measures for effective human-animal conflict management.

  • Invasive Alien Species and their Management

    Why in the news?

    The Andaman and Nicobar Islands administration sought assistance from the Wildlife Institute of India to manage the increasing population of chital (spotted deer) in Ross Island, officially known as the Netaji Subhash Chandra Bose Island.

    Chital in Andaman Islands

    • The Chital, originally native to mainland India, were introduced to Ross Island (0.3 sq km) by the British in the early 20th century.
    • Lacking natural predators or competitors and possessing strong swimming abilities, the Chital rapidly proliferated across the Andamans.

    About Chital(spotted deer)

    • The Spotted Deer, scientifically known as Axis axis, is a species of deer native to the Indian subcontinent.
    • It is characterized by its reddish-brown coat adorned with white spots, particularly prominent in juveniles.
    • Spotted Deer inhabit various types of forest habitats, including dry and moist deciduous forests, grasslands, and open woodlands.
    • The Spotted Deer is classified as a species of Least Concern (LC) on the IUCN Red List and Schedule II animal under Wildlife Protection Act, 1972.

    Definition of Invasive Alien Species (IAS):

    • The Convention on Biological Diversity (CBD) defines invasive alien species (IAS) as species whose introduction and/or spread outside their natural past or present distribution poses a threat to biological diversity.
    • These species encompass animals, plants, fungi, and even microorganisms, and can affect various types of ecosystems.
    • According to the CBD, characteristics of IAS include their ability to “arrive, survive, and thrive” in new environments.
    • The Invasive Species Specialist Group (ISSG) is a global network of scientific and policy experts on invasive species, organized under the auspices of the Species Survival Commission (SSC) of the International Union for Conservation of Nature (IUCN)

    Legal Definition in India:

    • In India, the legal definition of IAS, as per the Wildlife Protection Act, 1972 (amended in 2022), is narrower.
    • It refers to species of animal or plant not native to India whose introduction or spread may threaten or adversely impact wildlife or its habitat.
    • Notably, this definition EXCLUDES species within India that may be invasive to specific regions, such as the chital in the Andamans.

    Examples of Invasive Wildlife in India:

    1. Fish Species:
      • Examples include the African catfish, Nile tilapia, red-bellied piranha, and alligator gar.
      • These species were introduced to fulfill the demand for maintaining aquariums.
      • Reports indicate their presence in various inland systems and lakes in India.
    2. Turtle Species:
      • Notably, the red-eared slider, a favored exotic pet in India, is often abandoned in local water bodies.
      • Originating from North America, this species is known for outcompeting local freshwater species due to its rapid reproduction.

    Impact of IAS on Native Flora and Fauna

    1. Disruption of Ecosystem Balance:
      • Invasive species act as disruptors in the food chain, disturbing the balance of ecosystems.
      • In habitats lacking competition, invasive species can dominate the entire ecosystem.
    2. Specific Examples:
      • In Keoladeo Park, Bharatpur, Rajasthan, a UNESCO World Heritage site, the African catfish has been observed preying on waterfowl and migratory birds.
      • Studies have shown that the proliferation of chital in the Andamans has negatively impacted the regeneration of native vegetation, as these deer are known to consume seeds and seedlings.

    IAS’ Economic Impact:

    1. Global Perspective:
      • A report by the UN-founded Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES) in September 2023 revealed that approximately 37,000 established alien species were introduced worldwide, with roughly 200 new alien species introduced annually.
      • The economic cost of IAS globally surpassed $423 billion annually in 2019, primarily due to the damage inflicted on natural ecosystems.
    2. Local Implications:
      • In India, the National Biodiversity Action Plan of 2019, published by the National Biodiversity Authority, highlighted the economic impact of invasive species such as the cotton mealybug (Phenacoccus solenopsis).
      • This invasive species, native to North America, has significantly affected cotton crops in the Deccan region, leading to substantial yield losses.

    About Jenu Kuruba

    • The Jenu Kuruba tribe, numbering around 37,000, resides primarily in the Nilgiris region, bordering Kerala and Karnataka.
    • Their traditional occupation involves collecting honey in the forest, reflected in their name where ‘Jenu’ means ‘honey’ in Kannada.
    • In the early 20th century, they lived in forest huts and engaged in cultivation.

    Social organization of Jenu Kurubas’

    • They speak the Jenu Kurumba language, which is related to Kodava or considered a rural dialect of Kannada.
    • Historically, they engaged in activities like food gathering, collecting minor forest produce, and handling elephants.
    • They typically reside in small settlements known as Hadi and practice shifting cultivation.
    • Social organization within the community is semi-nomadic, with decentralized authority led by a head-man (yajamana) and a ritual head or shaman (gudda).

    Their rehabilitation

    • The tribe has fought for their rights to live in reserved forests, most recently in 2020 under the Forest Rights Act.
    • In 2021, protests continued against the forest department for promoting eco-tourism and safaris, which are deemed illegal under Indian and international laws.
    • From the 1970s onwards, many Jenu Kurubas have been evicted from their homes due to conservation efforts in tiger reserves like Nagarhole and Bandipur.

  • India’s Soil Erosion Trends: Insights from a New Study

    Why in the news?

    • Titled “Geospatial modelling and mapping of soil erosion in India,” the report marks the first attempt to classify soil erosion on a pan-India basis.
    • The study categorizes soil erosion into six classifications, ranging from “minor” to “catastrophic,” based on the amount of soil eroded per hectare over a year.

    Soil Erosion in India

    • Soil erosion is the process by which soil is removed or displaced from its original location, often due to the action of wind, water, or human activities.
    • It is a natural geological process accelerated by various factors such as deforestation, overgrazing, improper agricultural practices, urbanization, and climate change.

    Key trends in India

    • Nearly 30% of the country’s landmass is experiencing “minor” soil erosion.
    • Critical 3% (approx. 1500 sq km) faces “catastrophic” topsoil loss.
    • The Brahmaputra Valley in Assam emerged as the most significant hotspot for soil erosion, with close to 300 square kilometers or 31% of its surface soil lost to “catastrophic” erosion.
    • The lower Himalayan region, extending from Kashmir to Uttarakhand and beyond, and Odisha also face severe erosion challenges, posing threats to biodiversity and environmental stability.

    Causes of Soil Erosion

    1. Anthropogenic Causes: Soil erosion in India is primarily caused by human activities including deforestation, overgrazing, improper land use practices, and construction activities.
    2. Natural Causes: The monsoon season, characterized by heavy rainfall, exacerbates soil erosion, especially in regions with steep slopes and poor vegetation cover.

    Impact of Soil Erosion

    • Topsoil, essential for agriculture due to its nutrient-rich composition, is crucial for sustaining crop growth.
    • Erosion diminishes soil fertility, leading to reduced crop yields and agricultural productivity.

    Revised Universal Soil Loss Equation (RUSLE) Methodology 

    • The Revised Universal Soil Loss Equation (RUSLE) is a widely used empirical model for estimating soil erosion rates.
    • It is used to predict the average annual soil loss caused by sheet and rill erosion from specific field areas.
    • The RUSLE methodology considers various factors that contribute to soil erosion, including rainfall, soil erodibility, slope length and steepness, vegetation cover, and conservation practices.
    • The equation for RUSLE is:

    A = R * K * LS * C * P

    Where:

    A is the estimated average annual soil loss (in tons per acre per year).

    R is the rainfall factor, representing the erosive power of rainfall.

    K is the soil erodibility factor, representing the susceptibility of soil to erosion.

    LS is the slope length and steepness factor, accounting for the effect of slope on erosion.

    C is the cover management factor, indicating the impact of vegetation cover and land use practices on erosion.

    P is the conservation practice factor, reflecting the effectiveness of erosion control practices implemented.

     

    PYQ:

    [2014] In India, the problem of soil erosion is associated with which of the following?

  • Heat affects India’s aim to move from coal to renewables

    Why in the News? 

    The India Meteorological Department (IMD) recently said that India will have more than the ‘usual’ number of days with heat waves in this summer.

    Increasing Temperature in India and its impact as per IMD:

    • Temperature Predictions: The Indian Meteorological Department (IMD) predicts “above-normal” temperatures for April-June 2024, with a probability of 55%-65% in one half of the country and over 65% in the other half. Few parts are expected to have normal or below-normal temperatures.
    • Effect of Heat on Agriculture: Higher heat negatively impacts crop yield, agricultural workers’ productivity, and water availability, varying in degree depending on the crop.
    • Consequences of Heat in Urban Area: Increased heat leads to higher power demand in urban and industrial centers, poses deadly risks for outdoor workers (such as at construction sites), overwhelms health service providers (especially affecting the very young and old), and highlights the importance of access to clean, cool water, indoor ventilation, and bathrooms.
    • Power Demand: The availability of power is crucial for addressing the effects of heat. A chart shows that in March 2024, the average evening peak-hour demand reached a new high of 190 GW.

    Major challenges around the Energy Demand and Government Targets:

    • Government Targets: The government aims to achieve 500 GW of power generation capacity from renewable energy sources by 2030. Additionally, it has committed to producing 50% of its power from non-fossil fuel energy sources by the same year.
    • Heat increases power demand: Heat boosts power demand in cities and industries, heightens risks for outdoor labor, strains healthcare services for vulnerable groups, and underscores the necessity of clean water, ventilation, and bathrooms. Power availability is fundamental for addressing these challenges.
    • Focus on Solar Power: A substantial portion of the renewable energy addition will come from solar power. However, due to the intermittent nature of solar output and the ongoing establishment of power storage capacity, coal is still relied upon to meet peak demand.
    • Coal’s Dominance: Chart 3 (above) illustrates the gross electricity generated using coal in India and coal’s share in total electricity generation. The coal’s share has remained between 70-74% since at least FY16.
    • Commercially Viable Energy Storage: In India, the most commercially viable energy storage forms currently are battery-based and Pumped Hydro Storage (PHS).
    • Renewable Energy Generation: Chart 4 depicts the gross electricity generated using renewable sources in India and the share of renewable sources in total electricity generation. The share of renewables, including solar, hydro, wind, etc., has remained between 20-25% since at least FY16

    Major Dilemma For India: Cannot ignore Coal immediately:

    • Coal is projected to continue as the backbone of the Indian energy system until the next two decades and its phase-down will require active policies on critical minerals, according to a report by the Indian Institute of Management (IIM)- Ahmedabad.
    • The report, titled ‘Synchronising energy transitions towards a possible Net Zero for India: Affordable and Clean Energy for All,’ asserted that net zero is not possible without substantial nuclear power and renewable energy generation by 2070.
    • To achieve net-zero energy systems by 2070, the report mentioned that the electricity sector will need to decarbonize well before that.

     

    Way Forward: 

    • NDC Goals: The remaining gaps in emissions will be offset through sequestration in forestry and tree cover as envisaged in our Nationally Determined Contributions (NDCs).
    • Need for Technological intervention: There is no silver bullet to achieve net zero. The transition needs multiple pathways to be adopted with the co-existence of myriad technologies in our energy basket.
