  • In news: Mayor’s Election

    mayor
    PC: Hindustan Times

    Introduction

    • The Supreme Court has nullified the outcome of the mayoral election held on January 30 in Chandigarh.

    Who is a Mayor?

    • In India, the mayor is the head of an urban local body, which is responsible for providing essential services and infrastructure to the residents of a city or town.
    • The mayor is usually elected by the members of the Municipal Corporation or Council.
    • He/She serves as the ceremonial head of the local government.

    History of Mayor’s elections in India

    • Municipal corporation mechanisms in India was introduced during British Rule with formation of municipal corporation in Madras (Chennai) in 1688, later followed by municipal corporations in Bombay (Mumbai) and Calcutta (Kolkata) by 1762.
    • However the process of introduction for an elected President in the municipalities was made in Lord Mayo’s Resolution of 1870.
    • Since then the current form and structure of municipal bodies followed is similar to Lord Ripon’s Resolution adopted in 1882 on local self-governance.
    • The 74th Constitutional Amendment Act of 1992 was introduced providing for the transfer of 18 different powers to urban local bodies, including the election of a mayor and to recognise them which included Municipal Corporations, Nagar Panchayats, and Municipal Councils.

    Elections and tenure

    • The method of electing mayor and their tenure varies for each city in India.
    • In Bengaluru (Karnataka) the election process is indirect with a tenure being for one year.
    • In Mumbai (Maharashtra) it follows indirect elections with tenure for 2.5 years and Bhopal (Madhya Pradesh) follows a directly elected mayor with a term for 5 years.

    Roles and Responsibilities

    • Governs the local civic body.
    • Fixed tenure varying in different towns.
    • First citizen of city.
    • Has two varied roles:
    1. Representation and upholding of the dignity of the city during ceremonial times and
    2. Presiding over discussions of the civic house with elected representatives in functional capacity.
    • The Mayor’s role is confined to the corporation hall of presiding authority at various meetings relating to corporation.
    • The Mayor’s role extends much beyond the local city and country as the presiding authority at corporation meetings during visits of a foreign dignitary to the city as he is invited by the state government to receive and represent the citizens to the guest of honour.
    • At government, civic and other social functions he is given prominence.

    • This order came during the hearing of a public interest litigation challenging the constitutionality of the Forest (Conservation) Act, which was amended by the Union government in 2023.

    Why such move?

    • The petitioners highlighted concerns that the 2023 amendment had narrowed the expansive definition of ‘forest’ provided in the Godavarman judgement.
    • They argue that this move potentially aims at diverting forest lands for non-forest use.

    What is Godavarman Judgement?

    • The Godavarman Judgment is a landmark environmental case in India, first heard in the Supreme Court in 1996, commonly referred to as the “Godavarman Case.”
    • Originating as a PIL filed by Mr Godavarman, a retired forest officer, it addressed concerns about forest degradation due to various developmental activities without proper environmental clearances.

    Key Legal and Regulatory Framework

    • Forest Conservation Act (FCA) and Rules: The case primarily interprets and implements the Forest (Conservation) Act, 1980, and the Forest (Conservation) Rules, 1981, aiming at forest conservation and wildlife protection.
    • Powers of Central Government: The FCA empowers the central government to declare areas as “reserved forest” or “protected forest,” prohibiting non-forest activities without prior approval. It extends to all forests in India, not just declared reserves.
    • Defining Forest: The order defined as any area recorded as forest in the Government record irrespective of the ownership. This definition is broad and encompasses any area recorded as a forest in government records, regardless of its legal status or ownership.
    • Analysis:
    1. Diversion of Forest Land: The case tackled the diversion of forest land for non-forest purposes, emphasizing compliance with the law and due diligence.
    2. Extent of Central Government’s Powers: It clarified that the central government’s authority under the FCA extends to all forests, irrespective of ownership, emphasizing stringent regulation.
    3. Emphasis on Sustainable Development: The court stressed the importance of sustainable development in forest conservation and protecting the rights of forest dwellers and tribal communities.

    Impact of the Judgement

    • Strengthening Forest Conservation Laws: The case led to stricter interpretation and implementation of forest laws, focusing on conservation and protection.
    • Increased Judicial Role in Environmental Governance: It established the judiciary as a watchdog in environmental governance, promoting public scrutiny of environmental decisions.
    • Protection of Forest Lands: Resulted in the cancellation of projects diverting forest land, contributing to biodiversity conservation.
    • Recognition of Rights: Emphasized the recognition and protection of rights of forest dwellers and tribal communities.

    • Recording Forest Land: State and UT administrations are directed to prepare records on forest land within a year from the notification of the 2023 amendment as per Rule 16 of the Van (Sanrakshan Evam Samvardhan) Rules, 2023.
    • Expert Committees: The Union government is instructed to provide a comprehensive record of land registered as ‘forest’ by expert committees constituted by states and UTs within two weeks.
    • Compliance Deadline: All states and UTs must comply with the directions by forwarding the reports of the expert committees by March 31, 2024.

    Additional Directions

    • Zoo and Safari Establishment: Any proposal for the establishment of zoos and safaris in forest areas other than protected areas shall not be finally approved without prior permission from the Supreme Court.
    • Exemption Clause: Section 5 of the Forest (Conservation) Amendment Act, 2023, exempts zoos and safaris from the definition of ‘forests’ within forest areas, excluding protected areas.
    • Government Undertaking: The Union government submitted an undertaking that no precipitative steps would be taken concerning forest areas as per the dictionary sense, in line with the Godavarman judgement.

    Conclusion

    • The Supreme Court’s interim order underscores the importance of preserving forest lands as per the Godavarman judgement and ensuring compliance with environmental protection measures.
    • It aims to safeguard the ecological balance and prevent misuse of forest resources for non-forest purposes.

    Back2Basics: Universal Definition of Forest

    • As per the Conference of Parties (CoP) 9-Kyoto Protocol, the forest can be defined by any country depending upon the capacities and capabilities of the country.
    • Forest- Forest is defined structurally on the basis of
    1. Crown cover percentage: Tree crown cover- 10 to 30% (India 10%)
    2. Minimum area of stand: area between 0.05 and 1 hectare (India 1.0 hectare) and
    3. Minimum height of trees: Potential to reach a minimum height at maturity in situ of 2 to 5 m (India 2m)

    India’s definition of Forests

    The definition of forest cover has clearly been defined in all the India State of Forest Report (ISFR) and in all the International communications of India.

    • The forest cover is defined as ‘all land, more than one hectare in area, with a tree canopy density of more than 10 percent irrespective of ownership and legal status.
    • Such land may not necessarily be a recorded forest area. It also includes orchards, bamboo and palm’.

    Classification of forest cover

    In ISFR 2021 recently published has divided the forest cover as:

    1. Inside Recorded Forest Area: These are basically natural forests and plantations of Forest Department.
    2. Outside Recorded Forest Area: These cover mango orchards, coconut plantations, block plantations of agroforestry.

    Forest Survey of India (FSI) Classification

    • FSI classifies forest cover in 4 classes.
    1. Very Dense forest: All lands with tree cover (including mangrove cover) of canopy density of 70% and above.
    2. Moderately dense forest: All lands with tree cover (including mangrove cover) of canopy density between 40% and 70%.
    3. Open forests: All lands with tree cover (including mangrove cover) of canopy density between 10% and 40%.
    4. Scrubs: All forest lands with poor tree growth mainly of small or stunted trees having canopy density less than 10%.

  • Secrets of Mimas: Saturn’s Smallest Moon

    mimas

    Introduction

    • Recent findings published in the journal Nature suggest that beneath the icy shell of Mimas, there lies a potential liquid ocean, challenging previous assumptions about the moon’s composition and internal dynamics.

    About Mimas

    Description
    Discovery Discovered by William Herschel on September 17, 1789.
    Characteristics Smallest and innermost of Saturn’s major moons.
    Size Diameter of about 396 kilometers (246 miles), making it one of the smallest known astronomical bodies that is rounded in shape.
    Features Known for its large Herschel Crater,

    Called as “Death Star” from the Star Wars films.
    Composition Mostly composed of water ice with a small amount of rock.
    Orbit Orbits Saturn at a distance of about 185,520 km (115,220 miles).
    Exploration Visited by the Cassini spacecraft, which captured detailed images of its surface during its mission to Saturn.

    Astronomical Insights

    • Potential Liquid Ocean: Scientists analyzed Mimas’s orbital motion using data from NASA’s Cassini spacecraft, concluding that the moon’s oscillations indicate the presence of either an elongated silicate core or a global ocean.
    • Librational Model: Calculations based on Mimas’s librations and orbital changes reached a deadlock, prompting consideration of a subsurface ocean. Theoretical models incorporating viscoelastic outer layers and hydrostatic interior interfaces suggested an ice shell thickness of 20-30 km.
    • Surface Heat and Eccentricity: Estimates indicate surface heat release of approximately 25 milliwatts per sq. m, expected to reduce Mimas’s eccentricity by half in 4-5 million years. Simulations suggest the ocean may have formed 2-25 million years ago, with potential hydrothermal activity.

    Implications and Findings

    • Comparative Analysis: Similarities between Mimas and Enceladus, another Saturn moon with a global ocean, hint at potential hydrothermal activity despite surface differences.
    • Ice Shell Composition: The viscoelastic nature of Mimas’s outer icy layer and hydrostatic interior interfaces align with observations, supporting the theoretical ice shell thickness determined through calculations.

  • Call for imposing Financial Emergency in Kerala

    In the news

    • The Supreme Court proceeded with hearing a suit filed by the State of Kerala against the Centre for alleged arbitrary interference in its financial matters, following unsuccessful negotiations between the two parties.
    • Earlier, Kerala Governor sought for the Presidential imposition of a financial emergency in the State under Article 360(1) of the Constitution due to dwindling situation of finances in the State.

    What is Financial Emergency?

    • Enshrined in Article 360: It is a vital provision aimed at addressing severe financial crises threatening India’s economic stability.
    • Declaration and Authority: It can be declared by the President upon satisfaction that the financial stability or credit of India or any part of its territory is under threat.
    • CoM Advice: The declaration is made based on the advice of the Council of Ministers, reflecting the collective responsibility of the executive branch.

    Legislative Approval

    • While the President can proclaim a Financial Emergency, its extension beyond two months needs approval from both Houses of Parliament.
    • Once approved, it remains in effect until revoked by the President, allowing for flexible management of financial crises.

  • La Nina impacted Air Quality in India: Study

    la nina

    Introduction

    • El Nino and La Nina events have long influenced India’s monsoon patterns, but a recent study suggests a novel connection between these weather phenomena and air quality, particularly during the winter months of 2022.

    Understanding El Nino and La Nina

    • El Nino and La Nina are two opposite phases of the El Nino-Southern Oscillation (ENSO) cycle.
    • ENSO is a naturally occurring phenomenon that involves the interaction between the ocean and atmosphere in the equatorial Pacific.

    Here is a detailed comparison of El Nino and La Nina

    El Nino La Nina
    Definition Warmer-than-normal sea surface temperatures Cooler-than-normal sea surface temperatures
    Frequency Every two to seven years Every two to seven years
    Duration Several months to a year or more Several months to a year or more
    Impact on winds Weakens trade winds, leading to changes in patterns Strengthens trade winds, leading to changes in patterns
    Impact on rains Reduces rainfall and can cause droughts Increases rainfall and can cause flooding
    Impact on temp. Warmer-than-average temperatures Colder-than-average temperatures
    Global effects Droughts in Asia and Africa, floods in Americas Floods in Asia and Africa, droughts in South America

    Impact on India

    El Nino La Nina
    Associated with weak monsoons and drought-like conditions in India Associated with above-normal rainfall and floods in India
    Sea surface temperature in the equatorial Pacific Ocean rises above normal levels Sea surface temperature in the equatorial Pacific Ocean drops below normal levels
    Changes in the atmospheric circulation patterns Changes in the atmospheric circulation patterns
    Shift in the location of the jet stream, affecting the strength and direction of the monsoon winds Increase in the strength of the monsoon winds, bringing more moisture and rainfall to India
    Results in reduced rainfall, dry spells, and heatwaves, leading to crop failures and water scarcity Excessive rainfall can also lead to floods and landslides, causing damage to crops and infrastructure

    El Nino and Indian Monsoon

    • El Nino and its impact on Indian monsoon: El Nino refers to abnormal warming of surface waters in the equatorial Pacific Ocean, which tends to suppress monsoon rainfall in India.
    • Phases of El Nino Southern Oscillation (ENSO): ENSO consists of three phases in the Pacific Ocean: El Nino, La Nina (abnormal cooling), and a neutral phase with sea surface temperatures close to long-term averages.
    • Ocean and atmospheric conditions: ENSO involves not only temperature abnormalities of sea surface waters but also atmospheric conditions, including differences in sea-level air pressure and wind strength and direction.
    • Southern oscillation and the role of winds: Southern Oscillation Index measures the difference in sea-level air pressure over the western and eastern sides of the Pacific Ocean, while wind patterns play a crucial role in ENSO.

    How La Nina impacted air quality?

    • Wind Direction Shift: The study identified a significant alteration in wind circulation patterns during the winter of 2022, with winds typically blowing from the northwest direction diverted towards the south due to the prolonged La Nina effect.
    • Anomalous Behavior: This deviation led to a bypass of pollutant-laden winds from Punjab and Haryana away from Delhi towards southern regions, impacting cities like Mumbai, Bengaluru, and Chennai.
    • Extended La Nina Effect: The persistence of La Nina conditions over three years intensified the impact on wind patterns, culminating in noticeable changes in air quality distribution across India.
    • Uncertainties and Further Exploration: While the study highlights the role of La Nina in altering wind circulation and subsequent air quality, uncertainties remain regarding the potential impact of El Nino events on air quality dynamics.

    Conclusion

    • The study underscores the need for continued exploration into the interplay between global weather phenomena like La Nina, local meteorological conditions, and air quality dynamics in India.
    • Understanding these complex relationships can inform policy measures aimed at mitigating air pollution and enhancing environmental resilience in the face of climate change challenges.

  • Human-Wildlife Conflict in Kerala: Causes and Remedies

    Introduction

    • The escalation of human-wildlife conflict incidents in Kerala, exemplified by recent protests in Wayanad, underscores the urgent need to address the underlying causes of such conflicts.
    • Kerala grapples with a surge in human-animal conflicts, predominantly involving elephants, tigers, bison, and wild boars, wreaking havoc in districts like Wayanad, Kannur, Palakkad, and Idukki.

    Understanding the Conflict

    • Geographical Dynamics: Kerala’s significant forest cover, encompassing nearly 30% of its area, juxtaposed with densely populated human settlements and agricultural plantations near wildlife habitats, sets the stage for frequent human-animal conflicts.
    • Magnitude of Conflict: State Forest Department data reveals over 48,000 incidents of crop damage due to human-wildlife conflict between 2013-14 and 2018-19, with wild elephants being the primary culprits, followed by wild boars and bonnet macaques.

    Root Causes of Conflict

    • Changing Land Use: Increased cultivation around wildlife habitats and changing cropping patterns exacerbate conflicts by encroaching upon natural habitats and altering animal migratory routes.
    • Conservation Efforts: While conservation initiatives have led to the resurgence of animal populations like elephants and tigers, they have inadvertently intensified conflicts due to habitat depletion.
    • Human Activities: Movement of livestock and humans in wildlife habitats, especially during odd hours, further exacerbates conflicts by triggering defensive responses from animals.

    Proposed Solutions and Their Efficacy

    • Physical Barriers: Strategies like elephant-proof trenches and solar power fences have shown promise in mitigating conflicts but face challenges such as inadequate maintenance and breaches by locals.
    • Eco-Restoration Policy: The Forest department’s plan to restore ecosystems by planting indigenous species aims to deter animals from agricultural lands, yet its effectiveness hinges on implementation and sustenance.
    • Early Warning Systems: Adoption of early warning systems, including drones and human watchers, could help track animal movements and prevent confrontations, but their widespread adoption remains limited.

    Addressing Challenges with Wild Boars

    • Culling Initiatives: While the state awaits approval to declare wild boars as vermin, local bodies have been empowered to cull them as a last resort, alongside strategies like capture, neutering, and relocation.
    • Eco-Sensitive Zone (ESZ): Despite the legislative assembly’s plea to exempt Kerala from ESZ norms, conservationists advocate for its implementation to mitigate conflicts, acknowledging the challenges posed by Kerala’s population density and land scarcity.

    Legal Framework and Conservation Initiatives

    [A] Wildlife Protection and Biodiversity Conservation

    • The Wildlife Protection Act, 1972: Encompassing measures to prohibit hunting, safeguard wildlife habitats, and establish protected areas, this act forms the cornerstone of India’s wildlife preservation efforts.
    • The Biological Diversity Act, 2002: Complementing existing legislation, this act, in alignment with the United Nations Convention on Biological Diversity, fortifies conservation endeavors without undermining other forest and wildlife laws.

    [B] National Conservation Strategies

    • National Wildlife Action Plan (2002-2016): Centered on fortifying protected area networks, conserving endangered species and their habitats, curbing wildlife trade, and promoting research and education, this plan embodies India’s commitment to wildlife preservation.
    • Project Tiger: A pioneering initiative under the Ministry of Environment, Forests, and Climate Change since 1973, Project Tiger aims to create safe havens for the majestic big cats within India’s national parks.
    • Project Elephant: Launched in 1992, this centrally sponsored scheme endeavors to protect elephants, conserve their habitats and ensure safe migration corridors, thereby safeguarding the iconic species’ future.

    Conclusion

    • Balancing conservation efforts with the safety and livelihoods of Kerala’s populace requires a multifaceted approach that addresses the root causes of human-wildlife conflicts.
    • Collaborative efforts involving stakeholders, stringent regulatory measures, and sustainable conservation practices are imperative to foster coexistence between humans and wildlife in Kerala’s diverse landscape.
