  • Central India’s land-use patterns, roads fragmenting gaur & sambar populations, threatening genetic diversity   

    Why in the news? 

    A recent study by the National Centre for Biological Sciences (NCBS) found that land-use alterations and road construction in central India affect the genetic connectivity of two prominent herbivores: the gaur and the sambar.

    What is Genetic diversity?

    • Genetic diversity refers to the variety and variability of genetic material within a species or population, essential for adaptation, resilience to environmental changes, and long-term survival of organisms.

    About National Centre for Biological Sciences (NCBS)   

    • NCBS is a premier research institute located in Bangalore, India that is part of the Tata Institute of Fundamental Research (TIFR) under the Department of Atomic Energy of the Government of India.
    • The mandate of NCBS is to conduct fundamental research in the frontier areas of biology, ranging from the study of single molecules to ecology and evolution.

    Observations made by the National Centre for Biological Sciences (NCBS)   

    • Impact of Habitat Modification: The NCBS study underscores the significant impact of habitat loss and fragmentation on wildlife populations, particularly highlighting how expanding linear infrastructure like highways and railway lines disrupts animal movement and genetic connectivity.
    • Genetic Connectivity of Herbivores: It is the first study in India to investigate the genetic connectivity of large herbivores, specifically the gaur and sambar, at a landscape scale. The research reveals how these species are affected differently by landscape features and human activities, influencing their genetic diversity and ability to adapt to environmental changes.
    • Conservation Urgency: The study emphasizes the urgent need for conservation measures in fragmented habitats, such as Umred Karhandla Wildlife Sanctuary in Maharashtra, where small and genetically isolated populations of herbivores require targeted interventions to ensure their survival and genetic health.
    • Methodological Advances: Using advanced genetic techniques like next-generation sequencing (NGS) and landscape genetics, the NCBS researchers demonstrated how these tools can provide crucial insights into population dynamics, genetic diversity, and the impacts of human-induced changes on wildlife populations.

    Present Issues from Tiger reserves and Wildlife sanctuaries in MP and MH

    • Habitat Fragmentation and Connectivity: Both states face significant challenges related to habitat fragmentation due to expanding linear infrastructure like highways and railway lines. These developments disrupt wildlife corridors essential for the movement of animals, leading to isolated populations and reduced genetic connectivity, as observed in the NCBS study.
    • Human-Wildlife Conflict: Increasing instances of human-wildlife conflict pose a threat to both animals and human communities living near tiger reserves and wildlife sanctuaries. Encroachment of habitat for agriculture and settlements often results in conflicts over resources and occasionally leads to casualties among both wildlife and humans.
    • Poaching and Illegal Wildlife Trade: Despite conservation efforts, tiger reserves and sanctuaries in MP and MH continue to face challenges related to poaching and illegal wildlife trade. Tigers and other endangered species are targeted for their skins, bones, and other body parts, driven by demand in illegal markets.
    • Resource Extraction and Mining: Mining activities and resource extraction near protected areas pose significant environmental threats. These activities not only lead to habitat destruction but also contribute to pollution and disturbance, affecting the overall ecosystem health and biodiversity of these regions.
    • Climate Change Impacts: The effects of climate change, such as erratic weather patterns and changing rainfall regimes, also impact tiger reserves and wildlife sanctuaries in MP and MH. These changes can alter habitat suitability for wildlife species, affecting their distribution, migration patterns, and ability to adapt to new environmental conditions.

    Way forward: 

    • Enhanced Habitat Connectivity and Protection: Implement measures to mitigate habitat fragmentation caused by linear infrastructure. This includes creating wildlife corridors over or under highways and railways to facilitate safe animal movement
    • Integrated Conservation and Community Engagement: Foster collaboration between local communities, conservation organizations, and government agencies to address human-wildlife conflict and illegal activities like poaching.

  • Delhi Preservation of Trees Act (DPTA), 1994

    Why in the News?

    The Supreme Court and the Delhi government are at loggerheads due to alleged felling of trees in the Asola-Bhati Wildlife Sanctuary under the Delhi Preservation of Trees Act (DPTA), 1994.

    Forest Cover in Delhi: ISFR Report Findings

    • Largest Cover: According to the ‘India State of Forest Report 2021’ (ISFR) published by the Forest Survey of India (FSI), Delhi has the largest forest cover among seven major megacities, with 195 sq. km, followed by Mumbai (110.77 sq. km) and Bengaluru (89.02 sq. km).
      • Delhi’s forest cover constitutes 13.15% of its geographical area, while its tree cover spans 147 sq. km (9.91%).
    • Growth over Time: Despite extensive urban development, the city’s overall green cover (forest and tree cover) has increased from 151 sq. km (10.2%) in 2001 to 342 sq. km (23.6%) in 2021.

    What is the case against the DDA?

    • The Supreme Court is hearing a contempt petition against DDA’s Vice Chairman for the felling of about 1,100 trees, in violation of the SC’s orders, for road expansion in the ridge area, which falls under the eco-sensitive zone around Asola-Bhati Wildlife Sanctuary.
    • On March 4, the DDA submitted an application to the SC seeking permission to cut trees for the construction of the Gaushala Road. The court directed the DDA to re-examine the proposal with the help of field experts.
    • An affidavit from the DDA’s Vice Chairman revealed that tree felling had already begun in February and continued for ten days. By February 26, all intended trees were cut down even before the application reached the SC. This material fact was not disclosed when the court heard the application on March 4.
    • The Bench reprimanded DDA for not providing records of the Delhi LG’s (Chairman of the DDA) February 3 visit to the site, which allegedly led to the tree felling order. The Delhi government was also reprimanded for usurping the Tree Officer’s authority in granting permission.
    • The apex court has halted the DDA’s work and directed a team from the FSI to assess the number of trees cut and the environmental damage.

    Law governing Tree Protection in Delhi:

    Delhi Preservation of Trees Act (DPTA), 1994 provides legal protection to trees in the national capital against actions that could harm their growth or regeneration.

    • The Act defines a tree as “a woody plant that has branches supported by a trunk or a body of at least 5cm diameter and is at least 1 metre high from the ground”.
    • Section 2 (h) of the Act defines “to fell a tree” to include severing the trunk from the roots, uprooting, bulldozing, cutting, girdling, lopping, pollarding, applying arboricides, burning, or any other damaging method.
    • Under Section 8, no tree or forest produce can be removed on any land without prior permission from the ‘Tree Officer’, even on privately owned property. The ‘Tree Officer’ must respond within 60 days after inspection.
      • Violations of this Act may result in imprisonment for up to one year, a fine up to ₹1,000, or both.
    • The Act outlines a ‘Tree Authority’ responsible for conducting tree censuses, managing nurseries, and reviewing government and private construction proposals.
    • Delhi’s Tree Transplantation Policy, 2020 mandates that 80% of identified trees slated for felling must be transplanted. However, an affidavit submitted by the government to the Delhi High Court in 2022 disclosed that only 33.33% of transplanted trees had survived.

Extreme weather events, sea-level rise, and environmental degradation disproportionately impact vulnerable populations. Governments have a legal obligation to curb climate change, and corporations must respect human rights by reducing emissions and adapting to climate impacts. Addressing climate change is crucial to upholding human rights and ensuring a sustainable future for all.

    Let’s learn!

    __ __

    Why in the news? 

    In a landmark judgment, the Supreme Court of India recently recognized a right to be “free from the adverse impacts of climate change” in “M.K. Ranjitsinh and Others vs Union of India”, deriving it from the right to life and the right to equality.

    Law to inform development choices 

    • Integrating Climate Objectives into Development: Ensure that low-carbon and climate-resilient futures are prioritized in routine decision-making at all levels of development. Embed climate objectives in the legal framework to guide sustainable development choices.
    • Grounding Climate Action in Social Justice: Design laws to protect vulnerable populations disproportionately affected by climate change. Ensure the energy transition is just and equitable, advancing social justice and inclusive development.
    • Adopting a Comprehensive and Flexible Approach: Move beyond top-down emission targets to address broader developmental choices and their long-term impacts. Establish well-defined legal procedures that promote continuous consideration of low-carbon and climate-resilient futures.
    • Building a Robust Institutional Framework: Create an institutional structure to strategize, prioritize, troubleshoot, and evaluate climate policies. Enhance governance capacity to ensure credible and accountable climate action across all levels of government.
    • Tailoring Framework Climate Laws to the Indian Context: Adapt elements of global framework climate laws to suit India’s specific needs, focusing on maximising development per unit of carbon emitted. Emphasize climate resilience and social equity, ensuring development progresses in a low-carbon direction while building resilience to pervasive climate impacts.

     Need for a Low-Carbon Development Body

    • Rigorous Policy Analysis and Knowledge Generation: Establish a knowledge body in government to rigorously analyze policy options and their potential futures. Enable informed decision-making through a comprehensive understanding of low-carbon development and resilience strategies.
    • Expertise and Technical Guidance: Create an independent ‘low-carbon development commission’ staffed with experts and technical personnel. Provide national and state governments with practical guidance on achieving low-carbon growth and resilience.
    • Deliberative Decision-Making and Stakeholder Consultation: Facilitate a platform for deliberative decision-making involving multiple stakeholders. Systematically consult vulnerable communities and those adversely affected by technological changes to ensure their concerns are heard and integrated, leading to more sustainable and inclusive policy outcomes.
    • Strategic Direction and Whole-of-Government Coordination: Form a high-level strategic body, or ‘climate cabinet,’ comprising key Ministers and representation from State Chief Ministers to drive climate strategy across government. Address the challenge of siloed decision-making by promoting a whole-of-government approach with dedicated coordination mechanisms.
    • Enhanced Governance and Legal Empowerment: Complement the role of the Ministry of Environment, Forest, and Climate Change with higher-level coordination bodies. Reinforce existing structures like the Executive Committee on Climate Change with clearly defined legal powers and duties to ensure effective implementation and accountability in climate governance.

    Role of State and Local Governments in Climate Law

    • Engagement with Federal Structure: Recognize the importance of India’s federal structure in climate governance. Acknowledge that crucial areas for emission reduction and resilience improvement, such as electricity, agriculture, water, health, and soil, are managed by State and local governments.
    • First Responders to Climate Impacts: Understand that climate impacts are felt first and most intensely at local levels. Ensure that any institutional structure or regulatory instrument engages meaningfully with subnational governments.
    • Access to National Scientific Capacity: Establish channels for subnational governments to access national scientific resources and expertise. Utilize the low-carbon development commission as an intermediary to enhance local climate scientific capacity.
    • Financing Local Action: Develop mechanisms for financing local climate actions. Align centrally-sponsored schemes with climate goals and require national departments to climate-tag expenditures to enhance local climate resilience.
    • Coordination Mechanisms and Unified Goals: Create coordination mechanisms for the Centre and States to consult on major climate decisions. Require periodic updates of medium-term climate plans from both Centre and States, built around unified climate goals.
    • State-Specific Solutions and Institutions: Enable States to develop complementary institutions to those at the Centre, providing local knowledge, strategy-setting, deliberation, and coordination functions. Foster the development of State-specific solutions that address unique local climate challenges.

    Steps taken by Government to address the impact of climate change: 

    • International Solar Alliance (ISA): Launched in 2015, this alliance aims to efficiently utilize solar energy and reduce dependence on non-renewable sources like fossil fuels.
    • One Sun, One World, One Grid (OSOWOG) project with the UK: This project aims to build and scale inter-regional energy grids to share solar energy globally.
    • Swachh Bharat Mission: This program emphasized cleaning India’s cities and villages by providing toilets for every household.
    • National Clean Air Programme: Launched in 2019 to reduce particulate matter concentrations in the atmosphere.

    About Great Indian Bustards

    • GIBs are the largest among the four bustard species found in India, the other three being MacQueen’s bustard, the lesser florican, and the Bengal florican.
    • GIBs’ historic range included much of the Indian sub-continent but it has now shrunken to just 10 percent of it.
      • Among the heaviest birds with flight, GIBs prefer grasslands as their habitats.
    • GIBs are mainly found in Desert National Park, Rajasthan.
    • Bustards face major threats, including habitat changes and collisions with power lines.
    • Protection accorded:
      • Birdlife International: uplisted from Endangered to Critically Endangered (2011)
      • Protection under CITES: Appendix I
      • IUCN status: Critically Endangered
      • Protection under Wildlife (Protection) Act: Schedule I

    What is the GIB Recovery Plan?

    • The proposal was prepared by the Wildlife Institute of India (WII).
    • The proposal includes:
      • Rewilding Bustards bred in ex-situ conservation centres,
      • Conducting detailed population studies, and
      • Developing artificial insemination techniques.

    Back2Basics: Wildlife Institute of India (WII)

    • WII is an autonomous institution under the Ministry of Environment, Forest and Climate Change.
    • It was established in 1982.
    • It is based in Dehradun, Uttarakhand.
      • Functions: It offers training programs, academic courses, and advisory in wildlife research and management.

    Why such a move?

    • Indicator Species: The GIB is a key indicator species of grassland habitat, signalling the health of these environments.
    • Population Decline: The population has declined from around 700 individuals to less than 150 due to habitat loss, predation, and death by overhead power lines.
    • Supreme Court Order: The Supreme Court recognized the threat from power lines and constituted an expert committee to assess the feasibility of overhead and underground electric lines in the bustard’s habitats.

    Conservation Efforts and Achievements

    • Recovery Plan: Initial efforts began between 2012-2013 with a long-term recovery project, which firmed up in 2016 with a Rs 33.85 crore funding outlay.
    • Funding and Agreements: The project was funded by the Compensatory Afforestation Fund, with a tripartite agreement in 2018 involving the Environment Ministry, Rajasthan Forest Department, and WII.
    • In-Situ Breeding: Conservation breeding began in 2019, resulting in a founder population of 40 GIBs at the Ramdevra centre.

    Achievements at Breeding Centres

    • Successful Breeding: Eggs collected from the wild were incubated and chicks were hand-reared. The breeding centres now have a founder population of 40 GIBs.
    • Scientific Reasoning: Creating a founder population prevents extirpation and captures genetic variability. The goal is to have at least 20 adult birds including 15 females.

    Future Plans

    • Next Phase (2024-2033): The immediate next phase will run until 2029, targeting the upgradation of the CBC at Ramdevra and the development of the Lesser Florican CBC at Sorsan.
    • Population Surveys: Surveys will be conducted in Rajasthan and other range states to monitor population status.
    • Release into the Wild: The most important target is releasing captive-bred GIBs into the wild, preceded by soft release in enclosures.

  • [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.
