Pending Supreme Court Case on the Places of Worship Act, 1991

Source: The Hindu

UPSC Daily Current Affairs: 30th November 2024 | Current Affairs & Hindu Analysis: Daily, Weekly & Monthly

Why in News?

The Supreme Court is currently reviewing an important case regarding the Places of Worship (Special Provisions) Act, 1991. This law is designed to maintain the religious character of places of worship as they existed on August 15, 1947. Despite the significance of this case, progress has been slow, with the Union government remaining non-committal on the issue.

The Places of Worship (Special Provisions) Act, 1991:

  • Background:
    • The Act was enacted by the P V Narasimha Rao-led Congress government during the peak of the Ram temple movement.
  • Key Provision:
    • The Act mandates that the religious nature of all places of worship, except the one in Ayodhya which was under litigation at that time, must remain as they were on August 15, 1947.
  • Objective:
    • It prohibits the conversion of any place of worship.
    • It aims to maintain the religious character of places of worship as they existed on August 15, 1947.
  • Scope:
    • The Act restricts individuals from filing lawsuits to reclaim religious sites.
  • SC Verdict:
    • In the 2019 Ram Janmabhoomi-Babri Masjid case, the Supreme Court emphasized that the Act represents a legislative intervention that preserves non-retrogression, an essential feature of India's secular values.

Legal Challenges w.r.t. the Places of Worship Act, 1991:

  • Petitioners’ Argument:
    • Petitioners claim that the Act unjustly denies Hindus, Jains, Buddhists, and Sikhs their right to reclaim places of worship that were allegedly seized during historical invasions.
    • They view the Act as a barrier to addressing past injustices.
  • Counter Argument:
    • The All-India Muslim Personal Law Board defends the Act, arguing that it upholds the principles of secularism and fraternity, which are fundamental to the Constitution's Basic Structure.
    • Muslim representatives assert that the Act plays a critical role in maintaining national harmony by preventing the historical misuse of claims to oppress contemporary and future generations.
  • SC Proceedings:
    • The Supreme Court has yet to reach a resolution in this four-year-old case. The last significant order, issued on November 30, 2023, highlighted the Union government's failure to respond to the matter.
  • Contrasting Actions by the Courts:
    • Ajmer Sharif Dargah Case: Rajasthan courts have issued notices to the Minority Affairs Ministry and the Archaeological Survey of India (ASI) concerning claims that the dargah was constructed over a Shiva temple.
    • Shahi Jama Masjid, Sambhal: A local court in Uttar Pradesh has ordered a survey following claims that it was built by Emperor Babar on a demolished temple site.
    • Gyanvapi Mosque: The Supreme Court has allowed a scientific survey to continue at the mosque site, excluding excavation, after claims of a "shivling" discovery.
    • Shahi Eidgah Case: The apex court has stayed a High Court order that permitted a survey at the Eidgah mosque in Mathura.

Concerns Raised by Muslim Representatives and Judicial Response:

  • Survey Modus Operandi:
    • Experts have described ongoing surveys as part of a systematic approach to challenge the integrity of religious sites, addressing one claim at a time.
  • Calls for Action:
    • Muslim parties, including those managing the Gyanvapi mosque, have called on the Supreme Court to enforce the Act and prevent frivolous claims.
  • Judicial Response:
    • Former Chief Justice D.Y. Chandrachud emphasized the need to balance faith and legality, noting that what may seem trivial to some could be a genuine expression of faith for others.

Conclusion:

  • The ongoing case related to the Places of Worship Act highlights the tension between historical grievances and the constitutional values of secularism and unity.
  • As the Supreme Court continues its deliberations, differing judicial actions at local levels are intensifying discussions surrounding religious and cultural identity in India.
  • Finding a resolution to this matter is essential for maintaining communal harmony and upholding the rule of law.

New study: more than 1.5 million die each year from wild/bush fire pollution

Source:Indian Express

UPSC Daily Current Affairs: 30th November 2024 | Current Affairs & Hindu Analysis: Daily, Weekly & Monthly

Why in news?

A recent study published in The Lancet has highlighted a grave issue regarding pollution from landscape fires. Specifically, it indicates that agricultural burning in northern India during the winter months has resulted in over 120,000 deaths annually between 2000 and 2019 due to air pollution caused by these fires. This alarming statistic underscores the severe health risks associated with wildfire pollution.

What is Wildfire and Its Types?

  • Wildfires refer to uncontrolled fires occurring in natural landscapes, including forests, grasslands, and savannas. They can arise from natural events like lightning or human activities such as land clearing and agricultural burning.

Types of Wildfires

  • Forest Fires: These fires occur in wooded regions, spreading rapidly due to dry weather and strong winds.
  • Grassland Fires: Also known as prairie fires, these ignite in grasslands and can promote ecosystem regeneration but can also be devastating when uncontrolled.
  • Vegetation Fires: These fires affect shrublands and other vegetation types, often worsened by drought conditions.
  • Agricultural Burning: A prevalent practice in many areas, especially in northern India during winter, where farmers burn crop stubble to prepare fields for new planting, significantly contributing to air pollution.

What are the Global and Local Impacts of Landscape Fire Pollution?

  • Global Impact:
    • Death Toll: The study estimates that landscape fires cause over 1.53 million deaths annually worldwide due to air pollution, primarily affecting low- and middle-income countries.
    • Health Risks: Approximately 450,000 deaths each year are linked to cardiovascular diseases, while 220,000 are associated with respiratory diseases due to fine particulate matter (PM2.5) emitted by these fires.
    • Geographical Disparities: Countries such as China, the Democratic Republic of Congo, India, Indonesia, and Nigeria exhibit the highest mortality rates from fire-related air pollution.
  • Local Impact (India):
    • Annual Deaths: In India, landscape fires have contributed to approximately 2.55 million deaths from respiratory and cardiovascular issues from 2000 to 2019, averaging over 120,000 deaths each year.
    • Seasonal Pollution: Northern India faces severe air quality problems during winter (October to December) due to agricultural burning, compounded by cooler temperatures that trap pollutants near the ground.
    • Socio-Economic Factors: The study reveals that deaths from wildfires are four times more prevalent in low-income countries compared to high-income nations, indicating that poorer regions are at greater risk from fire-related air pollution.

What are the steps taken by the Government to the wildfire?

  • Forest Protection Division: This division, led by the DIG of Forests, oversees forest fire management at the national level.
  • Community Involvement: The government promotes active participation of local communities in forest fire management through initiatives like Joint Forest Management Committees (JFMCs) and Eco-Development Committees (EDCs).
  • National Action Plan for Forest Fires (NAPFF): Introduced in 2018, this plan aims to reduce forest fires by enhancing collaboration between local communities and state forest departments.
  • Forest Fire Prevention and Management Scheme (FPM): This is a government initiative designed to help states effectively manage and prevent forest fires.

Way forward:

  • Strengthen Community-Based Management: Improve capacity building, training, and incentivization for local communities through JFMCs and EDCs to actively prevent and manage wildfires.
  • Leverage Technology and Research: Implement advanced monitoring technologies like satellite-based fire detection and encourage research into fire-resistant vegetation to lessen the impact of wildfires and associated air pollution.

Indians Need to Share Contraceptive Responsibility

Source:The HinduUPSC Daily Current Affairs: 30th November 2024 | Current Affairs & Hindu Analysis: Daily, Weekly & Monthly

Why in news?

India has a longstanding commitment to family planning, initiated in 1952 with the goal of enhancing maternal and child health while controlling population growth. Over time, the program has adapted; however, a significant issue persists—an evident gender gap in the adoption of permanent contraceptive methods. This gap highlights systemic barriers to gender equality, particularly concerning Sustainable Development Goal 5, which aims to empower all women and girls by 2030.

The Decline of Male Sterilisation

  • In the late 1960s, vasectomies accounted for over 80% of sterilisation procedures in India.
  • Recent policy shifts, societal attitudes, and misconceptions have contributed to a sharp decline in male sterilisation rates.
  • Data from the National Family Health Survey (NFHS) indicates a consistent decrease in male sterilisation, with NFHS-4 (2015-16) and NFHS-5 showing no improvement.
  • This decline contradicts the National Health Policy of 2017, which aimed to raise male sterilisation rates to 30%.

Reasons Behind Disparity between Male and Female Sterilisation Rates in India

Societal Expectations and Responsibility

  • In many Indian communities, family planning is viewed primarily as a woman's duty.
  • This perception is reinforced by cultural norms that designate women as primary caregivers, forcing them to manage reproductive health.
  • Consequently, men often evade responsibility, seen as the family breadwinners.
  • This entrenched mindset leaves women to bear the physical and emotional consequences of sterilisation.

Myths and Misconceptions About Vasectomies

  • Widespread myths contribute significantly to the low acceptance of vasectomies.
  • Many men fear that the procedure will diminish their masculinity or sexual performance, despite contrary medical evidence.
  • Such fears are exacerbated by misinformation that portrays vasectomy as a means of emasculation.
  • This lack of accurate information discourages men from considering vasectomies, even though they are generally safer than female sterilisation.

Economic and Practical Barriers

  • Economic factors also deter men from opting for vasectomies.
  • In many families, male income is crucial; thus, the idea of taking time off work is daunting for daily wage earners.
  • Although the government offers cash incentives for missing work, awareness of these initiatives is low.
  • Women in a 2024 field study in Chhatrapati Sambhaji Nagar, Maharashtra, expressed that vasectomies could impose financial strain on their families.

Patriarchal Resistance and Female Reluctance

  • Resistance to male sterilisation is not limited to men; many women deem vasectomies as unnecessary or inappropriate for their husbands.
  • In patriarchal settings, women often internalise norms that assign reproductive duties solely to them.
  • Some women in rural areas believe that suggesting a vasectomy could be disrespectful or lead to marital strife.
  • This dynamic further entrenches gender inequalities and perpetuates the burden on women in family planning.

Lack of Skilled Healthcare Providers and Awareness

  • In rural regions, limited access to trained healthcare professionals exacerbates the issue.
  • Even when men express willingness to undergo vasectomies, the shortage of skilled practitioners poses a significant hurdle.
  • Community health workers, often the main source of medical information in these areas, are frequently uninformed about the benefits of modern vasectomy techniques.

Implications for Gender Equality

  • The gender disparity in sterilisation undermines broader gender equality and women's empowerment efforts.
  • When women disproportionately shoulder the responsibility for sterilisation, they face heightened health risks and disruptions to their lives and livelihoods.
  • Moreover, the narrative that places the burden on women reinforces harmful gender stereotypes, limiting shared responsibilities within families.
  • Addressing these disparities demands increased awareness of the safety and simplicity of vasectomies, alongside a cultural shift in perceptions of reproductive responsibilities.
  • Until men are encouraged to participate actively in family planning, achieving gender equality in India will remain an ongoing challenge.

Strategies for Promoting Vasectomy Adoption

Early Education, Awareness, Social and Behavioural Change Initiatives

  • Education on shared family planning responsibilities should start early, ideally in schools.
  • Introducing concepts of gender equality and reproductive health through peer discussions can challenge stereotypes and destigmatise vasectomies.
  • Consistent efforts to dispel myths surrounding vasectomies are essential.
  • Campaigns should highlight the safety and simplicity of vasectomies compared to tubectomies.

Enhanced Incentives and Learning from International Successes

  • Conditional cash incentives can significantly boost male participation in vasectomies.
  • A 2019 study in Maharashtra showed that financial incentives successfully encouraged more men in rural tribal regions to choose vasectomies.
  • The 2022 initiative in Madhya Pradesh to increase these incentives by 50% indicates a promising policy direction.
  • Countries like South Korea, Bhutan, and Brazil provide valuable insights; South Korea's high vasectomy rates are linked to progressive gender norms, while Bhutan's government-run camps and Brazil's media campaigns effectively increased male sterilisation rates.

Strengthening Health Systems

  • The Indian government must enhance its health infrastructure to align with policy objectives.
  • This includes training more healthcare providers to perform vasectomies and promoting advanced techniques like no-scalpel vasectomies.
  • Investments in awareness and accessibility are crucial for creating an environment where male sterilisation is seen as a feasible option.

Conclusion

  • The heavy reliance on women for sterilisation reflects deep-rooted gender inequalities in India's family planning initiatives.
  • Closing this gap requires more than just policy declarations; it demands actionable reforms that integrate education, incentives, and systemic changes.
  • By normalising vasectomies and addressing societal misconceptions, India can foster shared responsibility in family planning, paving the way for greater gender equality and improved reproductive health outcomes.

UPSC Daily Current Affairs: 30th November 2024 | Current Affairs & Hindu Analysis: Daily, Weekly & Monthly

Why in News?

The Phlegraean Fields, a significant supervolcano near Naples, Italy, are currently showing signs of activity, raising concerns among scientists.

Overview of Phlegraean Fields:

  • The Phlegraean Fields, known as 'Campi Flegrei' in Italian, represent an active volcanic region situated close to Naples.
  • Unlike the singular Mount Vesuvius, this area consists of multiple volcanic centers within a large sunken area termed a caldera.
  • This caldera measures approximately 12-15 km (7.5-9.3 miles) in diameter.
  • It was formed around 39,000 years ago following a significant eruption that drained its magma.
  • Some experts suggest this eruption may have contributed to the decline of Neanderthal populations.
  • Part of the caldera extends beneath the Tyrrhenian Sea, located between the Italian mainland and Sardinia.
  • Phlegraean Fields is recognized as Europe’s largest active caldera, surpassing the size of the cone-shaped Vesuvius, which famously devastated the city of Pompeii in AD 79.
  • This supervolcano is considerably more active than Vesuvius.

Current Activity:

  • Since 1950, the Phlegraean Fields have been in a state of unrest, attributed to a phenomenon known as bradyseism.
  • Bradyseism involves the slow movement of the Earth's surface due to the filling or emptying of an underground magma chamber or hydrothermal processes.
  • The last eruption occurred in 1538, after a dormancy of approximately 3,000 years, which formed the Monte Nuovo mountain.

Potential Impact:

  • Scientists regard the Phlegraean Fields as a supervolcano, capable of eruptions with global repercussions.
  • This volcanic region ranks among the world's top eight sources of volcanic carbon dioxide emissions.
