  • Why A23a is spinning in its place?

    Why in the News?

    • A23a, the world’s largest iceberg, has recently started spinning in place after drifting away from Antarctica in 2020.
      • Now it is near South Orkney Islands, about northeast of the Antarctic Peninsula.

    What is A23a?

    • A23a is an iceberg, about 3,855 square kilometers in area, which is 5 times the size of New York City.
    • It was originally part of an even larger iceberg called A23.
    • It broke off from the Filchner Ice Shelf in Antarctica in 1986.

    What is happening with A23a?

    • It is now trapped over a seamount, and is spinning slowly in place.
    • It is completing a full spin approximately in 24 days.
    • Reason behind the spinning: Icebergs spin in Iceberg Alley because they get pulled by the strong Antarctic Circumpolar Current, moving into warmer waters where they melt.

    Implications

    • A23a’s melting does not contribute to global sea level rise since it is already floating.
    • Its extended stay in this vortex could impact marine life in the area, especially plankton and other organisms in the food chain.
    • The situation also provides a unique opportunity for scientists to study how such large icebergs behave in the ocean.

    Mentor comments:  In April 2024, the Supreme Court of India delivered a significant judgment in the case of “M.K. Ranjitsinh and Others vs Union of India.” The two-judge bench, comprising Justice Sanjiv Khanna and Justice Dipankar Datta, ruled on the matter concerning the rights of wildlife and environmental protection. The court emphasized the importance of safeguarding natural habitats while balancing developmental needs, thereby reinforcing the legal framework aimed at preserving biodiversity and ecological integrity in India. This ruling reflects the judiciary’s commitment to environmental justice and sustainable development practices.

    Let’s learn!

    __

    Why in the News? 

    • In April 2024, the Supreme Court of India, in the case of “M.K. Ranjitsinh and Others vs Union of India”, acknowledged a human right to be free from the adverse effects of climate change. 
    • This landmark decision has generated considerable discussion, with varying opinions. For some, it represents a significant advancement in climate action, while others contend that it inadequately safeguards endangered biodiversity.

    Key points as per judgement: 

    • Recognition of Human Rights Against Climate Change: The Supreme Court’s judgement recognized a human right against the adverse impacts of climate change, marking a significant step in the realm of environmental jurisprudence in India.
    • Concept of Just Transition: The judgement emphasized the importance of framing climate action through the lens of “just transition.”  
    • Inclusion of the Non-Human Environment: A significant aspect of the judgement was the consideration of introducing the non-human environment, such as biodiversity and ecosystems, as a subject within the concept of just transition.  
    • Mixed Reactions: The decision has sparked diverse opinions. While it is seen as a victory for climate action, some critics argue that it has not sufficiently protected endangered biodiversity, especially species like the Great Indian Bustard.

    What is just a transition concept? 

    • The concept of just transition refers to a framework aimed at ensuring that the shift from a high-carbon economy to a low-carbon economy is equitable and inclusive, addressing the social, economic, and environmental impacts of this transition.

    Advantages of a just transition framing

    • Equitable Climate Action: Framing the case within a just transition context allows the court to promote equitable and inclusive climate action. It shifts the narrative from viewing decarbonisation and biodiversity protection as adversarial to recognising their interdependence.
      • This approach can prevent the marginalisation of biodiversity interests, ensuring that the burdens of climate action are shared fairly among all stakeholders, including affected communities and ecosystems.
    • Expansion of Just Transition Concept: The case provides a unique opportunity to broaden the just transition framework by incorporating the non-human environment, specifically the Great Indian Bustard, as an affected entity.
      • This inclusion can help develop jurisprudence that recognizes the rights of nature and expands the understanding of just transition beyond human communities, aligning with emerging eco-centric legal principles.
    • Catalyst for Research and Awareness: Introducing the just transition concept in this case can stimulate much-needed research on just transition litigation in India, an area that remains underexplored.
      • By mapping existing cases and integrating them into the broader discourse on just transitions, the court can contribute to filling gaps in knowledge and understanding of how climate justice can be effectively achieved in the context of renewable energy projects.

    Way forward: 

    • Developing a Comprehensive Legal Framework for Just Transition: The Supreme Court should advocate for the creation of a robust legal framework that explicitly incorporates the principles of just transition. This framework should provide clear guidelines for ensuring that climate action, particularly decarbonisation efforts, is inclusive and fair to all stakeholders, including vulnerable communities and ecosystems.  
    • Establishing a Multidisciplinary Task Force for Monitoring and Implementation: The Court could recommend the formation of a multidisciplinary task force comprising experts in environmental law, social justice, economics, and biodiversity conservation.  
  • Trichophyton indotineae: A drug resistant fungal infections   

    Why in the News?

    The increase in drug-resistant fungal infections, especially Trichophyton indotineae, is becoming a major health problem in India.

    What Is Trichophyton Indotineae?

    • Trichophyton indotineae is a dermatophyte commonly known as ringworm or jock itch.
    • First identified in India, this fungus has now spread to several countries worldwide.
    • It belongs to genotype VIII within the T. mentagrophytes/T. interdigitale species complex, found in regions including Australia and Oman.

    Factors causing its spread 

    • Patients often present with persistent, treatment-resistant rashes that can be mistaken for eczema or other skin conditions.
    • Misdiagnosis leads to the use of ineffective treatments, prolonging patient suffering and allowing the infection to worsen.
    • Trichophyton indotineae has shown resistance to terbinafine due to genetic mutations, with growing resistance to itraconazole also a concern.
    • The unregulated sale of steroid-containing combination creams further complicates treatment efforts.

    Treatments available

    • Alternative to terbinafine and Itraconazole are available but often come with significant side effects, requiring close monitoring by healthcare providers.
    • Integrating comprehensive skin care regimens can enhance treatment efficacy, including maintaining skin hydration and using barrier creams.

  • Country’s third largest tiger reserve to come up in Chhattisgarh

    Why in the News?

    Facing a significant decline in its tiger population in recent years, Chhattisgarh on Wednesday approved a long-awaited proposal to establish a new tiger reserve, which will be the third largest in the country.

    Process of Notification of Tiger Reserves

    • Proposal and Evaluation: The state government initiates the process by proposing an area to be designated as a tiger reserve. This proposal is then evaluated by the National Tiger Conservation Authority (NTCA).
    • Cabinet Approval: After NTCA’s recommendations, the state cabinet must approve the notification of the tiger reserve.
    • Integration of Areas: The Guru Ghasidas-Tamor Pingla Tiger Reserve integrates the existing Guru Ghasidas National Park and Tamor Pingla Wildlife Sanctuary, covering an area of 2,829 square kilometers.
    • Note: Once a tiger reserve is notified, it cannot be easily denotified. The Wildlife (Protection) Act, 1972, allows for denotification only under exceptional circumstances and with approval from the NTCA and the National Board for Wildlife.

    About Guru Ghasidas-Tamor Pingla Tiger Reserve

    • It is Chhattisgarh’s fourth tiger reserve, following Indravati, Udanti-Sitanadi, and Achanakmar.
    • The reserve spans four districts: Manendragarh-Chirmiri-Bharatpur, Koriya, Surajpur, and Balrampur.
    • It aims to bolster conservation efforts and provide a protected habitat for tigers, thereby promoting eco-tourism and creating employment opportunities for local communities.
    • It aims to bolster conservation efforts and provide a protected habitat for tigers by Providing additional budgetary resources from the National Project Tiger Authority for its operations.
    • It would promote eco-tourism and create employment opportunities for local communities.

    Tiger Reserves in India 

    • As of June 2024, India has 55 tiger reserves. This number has increased from 9 reserves in 1973 when Project Tiger was initiated. India is home to around 75% of the global tiger population.
    • The latest addition to the list is the Dholpur-Karauli Tiger Reserve in Rajasthan, which is the 55th reserve established in the country.
    • These reserves are crucial for the conservation of the Bengal tiger, which is a keystone species in India’s ecosystems, and they collectively support around 80% of the world’s tiger population.
    • Madhya Pradesh has the highest number of tigers at 785, followed by Karnataka (563), Uttarakhand (560), and Maharashtra (444).

    The initiative was taken by the Government: 

    • Strengthening Legal Framework: The Wildlife (Protection) Act, 1972 provides a legal framework for tiger conservation, establishing national parks, wildlife sanctuaries, and critical tiger habitats. The 2006 amendment led to the creation of the National Tiger Conservation Authority (NTCA).
    • Anti-Poaching Measures: Special Tiger Protection Force (STPF) has been deployed in tiger reserves to combat poaching. Modern surveillance technologies like camera traps and drones are used to monitor tiger populations and deter poaching activities.
    • To avoid human-tiger conflict: As of 2023, 12,327 families from 173 villages have been successfully relocated from tiger reserves to reduce human-tiger conflict.

    Way forward: 

    • Undertake habitat restoration measures in the tiger reserves, including prey base management and removal of invasive species, to improve the quality of tiger habitats.
    • Deploy the Special Tiger Protection Force (STPF) in the newly notified Guru Ghasidas-Tamor Pingla Tiger Reserve to curb poaching.

  • A closer look at beefng up Jammu’s counter-terror grid    

    Why in the news?

    The Jammu region has faced severe security issues recently, exacerbated by troop redeployment to the LAC. To address this, around 3,500 additional troops and Special Forces were deployed.

    Present Context of J&K

    • Security Concerns: The Jammu region has seen a resurgence in terrorist activities, with security forces suffering significant losses. The situation has deteriorated, particularly following the redeployment of troops to the Line of Actual Control (LAC) after the Galwan incident in June 2020.
    • Increased Military Presence: In response to the rising threats, additional troops, including Special Forces and Assam Rifles, have been inducted into the region to bolster counter-terrorism operations.
      • Following the abrogation of Article 370 in 2019, there has been a strategic shift in militancy from Kashmir to Jammu, with militants adapting their tactics and increasing their operational activities in districts like Reasi, Rajouri, and Poonch.

    Need to Establish the Grid System in Vulnerable Areas

    • Establishing a counter-terrorism grid involves deploying military units strategically in vulnerable areas to dominate potential terrorist movements. This requires thorough threat assessments based on terrain, local population inclinations, and historical data.
    • The grid system emphasizes the importance of winning the trust of the local population through community engagement, which is crucial for gathering intelligence on terrorist activities.

    Challenges

    • Integration of New Troops: Newly inducted troops face the challenge of quickly orienting themselves to the local terrain and population dynamics.
    • Divided Local Population: The local population is divided into subsets that either support the state, support terrorists, or remain neutral. 
      • Gaining the support of the neutral majority is critical for the success of counter-terrorism efforts.
    • Operational Control: Recent trends show a shift in operational control from battalion-level commanders to higher command levels, which can hinder effective and timely responses to emerging threats.

    About Operation Dudhi

    • Historical Context: Operation Dudhi, conducted in May 1991 by the 7 Assam Rifles, is remembered as a successful counter-terrorism operation in the Chowkibal area. It showcased the effectiveness of battalion-level command in conducting operations.
    • Lessons Learned: The operation highlighted the importance of allowing commanding officers to maintain control over their units.
      • Recent trends of centralizing control may undermine operational effectiveness and responsiveness.
    • Need for Integrated Deployment: The success of future operations requires that newly inducted troops be deployed as integral units under existing command structures, rather than in a fragmented manner, to enhance operational coherence and effectiveness.

    Way forward: 

    • Enhance Human Intelligence Networks: It is crucial to build robust human intelligence networks by integrating local informants and community members into counter-terrorism efforts.
    • Integrated Deployment of Forces: Newly inducted troops should be strategically integrated with existing units to create a cohesive counter-terrorism grid. This approach will facilitate knowledge sharing and operational synergy, allowing new troops to quickly acclimatize to the local environment and build relationships with the community.
