India’s Ageing Population

Source: IE 

Why in News?

Recently, some politicians of India’s Southern state expressed concerns about the ageing and shrinking population and emphasised a law to incentivise residents of the state to have more children.  

• The ageing population is a demographic trend with an increasing proportion of individuals aged 65 and older compared to the working-age population (15-64). 

What do Data Say on Ageing and Overall Population Size in India? 

• Overall Population Increase: India's population is projected to increase by 31.1 crore (311 million) between 2011 and 2036. 
• Concentration of Growth: Almost half i.e., 17 crore will be added in five states of Bihar, UP, Maharashtra, West Bengal, and Madhya Pradesh.  
• Regional Disparities: Uttar Pradesh is projected to account for 19% of total population growth, while the five Southern states Andhra Pradesh, Karnataka, Kerala, Telangana, and Tamil Nadu will contribute only 29 million, or 9% of the total growth. 
• Ageing Population Trends: The number of individuals aged 60 years and older is expected to more than double from 10 crore (100 million) in 2011 to 23 crore (230 million) by 2036, with their share of the total population rising from 8.4% to 14.9%. 

 

• State Variations in Ageing Population: In Kerala, the proportion of individuals aged 60 and older is projected to rise from 13% in 2011 to 23% by 2036, meaning nearly 1 in 4 individuals will be in this age group. 
  • In Uttar Pradesh, the share of the 60+ population is expected to rise from 7% in 2011 to 12% in 2036. 
• North-South Divide: The increase in the proportion of people aged 60 and older will be smaller in Northern states compared to the South. 
  • Southern states transitioned to lower fertility rates earlier. E.g., Uttar Pradesh is projected to reach the Replacement Level of Fertility (2.1 children per woman) in 2025, over two decades later than Andhra Pradesh (2004).

What are the Causes of Ageing and Shrinking Population? 

• Contraception and Family Planning: The increased availability of contraception and abortion services allows individuals to have greater control over their reproductive choices. 
• Women's Economic Participation: As women have increasingly entered the workforce, many have chosen to delay childbirth or forego having children altogether.  
  • This shift is often driven by career aspirations, financial stability, and the pursuit of personal goals. 
• Improved Child Survival Rates: According to the World Health Organization (WHO), the under-five mortality rate (deaths per 1,000 live births) in India declined to 34 in 2019 from 126 in 1990. 
  • Between 1990 and 2019, India achieved a 4.5% annual reduction in under-five mortality, decreasing deaths from 3.4 million in 1990 to 824,000 in 2019. 
  • Due to decline in the under-five mortality rate, people are less likely to give birth to more children. 
• Urbanisation: As more people move to urban areas, the cost of living often rises, making it more difficult for families to afford children. Urban lifestyles may also prioritise careers over family expansion. 
• Migration: Indian migration due to foreign countries like UAE and USA also leads to decline in India’s population. 

What Concerns are Associated with the Ageing Population? 

• Small Representation in Parliament: Southern states with an ageing population and consequently smaller populations fear they could end up getting penalised by way of fewer seats in Lok Sabha for having made the demographic transition before the North. 
  • Bihar, Madhya Pradesh, Rajasthan, and Uttar Pradesh might gain more political representation at the expense of Southern states, affecting policy priorities. 
• Slowing GDP Growth: An ageing population often leads to a decline in the growth rate of GDP primarily due to a decrease in the labour force. 
  • Eg. In the US, the growth of the 20 to 64-year-old population is expected to decrease from 1.24% per year (1975-2015) to only 0.29% (2015-2055) leading to a corresponding decline in the growth rate of GDP and aggregate consumption. 
• High Dependency Ratio: As the population ages, there will be a higher ratio of dependents (both elderly and children) to working-age individuals which increases the burden on the working-age population (15- to 64-year-olds). 
  • According to the World Bank collection of development indicators, India’s current age dependency ratio of 47% in 2023 is expected to rise significantly. 
• Higher Public Expenditure: The cost of public programs for health care, pensions, and long-term care will increase significantly as populations age.  
  • Governments will need to raise taxes or cut benefits to manage these rising costs.  
• Intergenerational Equity Issues: Younger populations might feel unfairly taxed to support the older generation, leading to potential societal divides and a sense of injustice regarding resource allocation. 
• Pressure for Institutional Reform: As the population ages, there may be growing calls for reforms in retirement age, social security benefits, and healthcare systems. 

How do Countries Respond to Ageing Population? 

• China’s Three-Child Policy: In 2016, China moved to allow its citizens to have two children and in 2021, China announced that families are permitted to have three children. 
  • From 1980 to 2016, China imposed a one-child policy, which slowed population growth. 
• Japan's Parental Leave: It includes mandating twelve-month parental leave, offering direct financial aid to parents, and investing heavily in subsidised childcare. 
• Extended Retirement Age: Some countries, such as France and the Netherlands, extended the retirement age or the age at which people are eligible for pension benefits to alleviate pressure on pension systems. 
• Open Immigration Policy: Australia, Canada, and other countries have adopted more open immigration policies to counter labour shortages due to their declining populations. 

What can be done to Arrest Ageing and Shrinking Population? 

• Pro-Natalist Policies: Scandinavian countries have demonstrated that family support, childcare, gender equality, and parental leave policies can help maintain fertility rates. 
  • Proper government funding of child healthcare and education can motivate people to have more children. 
• Leveraging Internal Migration: Internal migration between the more populous Northern states and the more developed Southern states can bring in working-age individuals, mitigating the impact of an ageing population. 
  • States receiving migrants would benefit from an immediate influx of labour without the need to invest in education and upbringing for young families. 
• Promoting Gender Equality: Gender equality initiatives promoting shared parenting responsibilities can potentially lead to increased fertility rates.

Global Hunger Index 2024

Source: TH

Why in News? 

Recently, India ranks 105^th out of 127 countries in the Global Hunger Index (GHI) 2024 with a score of 27.3, highlighting a "serious" hunger crisis driven by ongoing challenges of food insecurity and malnutrition. 

What are the Key Findings of the Report?

• India-Specific Findings: GHI Score (2024) - 27.3 (‘serious’) slightly improved from GHI Score (2023) - 28.7 (‘serious’).  
  • Undernourished children - 13.7%  
  • Stunted children - 35.5%  
  • Wasted children - 18.7% (highest globally)  
  • Child mortality rate - 2.9%

• Global Trends in GHI 2024:  
  • The 2024 GHI score for the world is 18.3, a slight improvement from 18.8 in 2016, and is considered "moderate."  
  • South Asian neighbours like Bangladesh, Nepal, and Sri Lanka perform better, ranking in the "moderate" category. 
• Recognizing India's Efforts: The report acknowledges India's significant efforts to improve the food and nutrition landscape through various initiatives such as Poshan Abhiyan (National Nutrition Mission), PM Garib Kalyan Yojana (PMGKAY), National Mission for Natural Farming. 
• Insufficient GDP Growth: The report highlights that Gross Domestic Product (GDP) growth does not guarantee reduced hunger or improved nutrition, urging the need for policies focused on pro-poor development and addressing social and economic inequalities. 

What is India's Response to GHI 2024? 

• Faulty Methodology: The Ministry of Women and Child Development criticized the absence of data from their Poshan Tracker, which reportedly indicates a much lower child wasting rate of 7.2%. 
• Focus on Child Health: The government noted that three out of the four GHI indicators pertain to children's health and may not provide a complete representation of the entire population. 
• Small Sample Size: The government expressed doubts about the accuracy of the "Proportion of Undernourished Population" indicator, as it is based on a small sample size opinion poll. 

What are the Challenges Related to Hunger in India?

• Inefficient Public Distribution System (PDS): Despite improvements, India's PDS still faces challenges in reaching all intended beneficiaries. 
  • The National Food Security Act covers 67% of the population, but more than 90 million eligible people have been excluded from legal entitlements under the Targeted Public Distribution System (TDPS). 
• Income Inequality and Poverty: While India has made strides in poverty reduction (24.82 crore Indians escape Multidimensional Poverty in the last 9 years), significant income disparities persist, affecting food access. 
• Nutritional Challenges and Dietary Diversity: Food security in India often focuses on calorie sufficiency rather than nutritional adequacy. 
• Urbanization and Changing Food Systems: Rapid urbanization in India is transforming food systems and consumption patterns.  
  • A 2022 study by the Tata-Cornell Institute found that 51% of urban slum households in Delhi experienced food insecurity.   
• Gender-Based Nutritional Gap: Gender-based disparities worsen hunger and malnutrition in India. Women and girls often face unequal access to food within households, receiving smaller portions or lower-quality meals.  
  • This inequity, combined with the demands of maternal and child care, increases their vulnerability to chronic undernutrition. 

Way Forward 

• PDS Enhancement: Revamp the Public Distribution System (PDS) to enhance transparency, reliability, and affordability of nutritious food, benefiting the economically disadvantaged. 
• Social Audit and Awareness: Implement social audits of the mid-day meal scheme in all districts with local authority involvement, enhance program monitoring through IT, and establish community-driven nutrition education programs in local languages, focusing on balanced diets for women and children. 
• Complementing With SDGs: The Sustainable Development Goals (SDG), particularly SDG 12 (Responsible Consumption and Production) and SDG 2 (Zero Hunger), focuses on sustainable consumption pattern. 
• Investment in Agriculture: A holistic food systems approach promoting diversified and nutritious food production, including nutri-cereals like millets. 
  • Addressing food wastage is critical. One key approach is improving warehousing and cold storage infrastructure to reduce post-harvest losses. 
• Health Investments: Focus on maternal and child health through better water, sanitation, and hygiene practices. 
• Interlinking Factors: In policy-making, it is crucial to recognize the interconnection between gender, climate change, and nutrition, as these factors significantly impact public health, social equity, and sustainable development.

Ban on Child Betrothals

Source: IE

Why in News?

The Supreme Court highlighted that marriages arranged during a child's minority infringe upon their "free choice" and "childhood," and urged the Parliament to outlaw child betrothals.

• According to the court, India had yet to fully address the issue of minor betrothals, despite the Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) recognizing the problem in 1977.
• The Prohibition of Child Marriage Act (PCMA) of 2006 criminalised child marriage but the practice of betrothal is not explicitly prohibited under the Act.

What is the Status of Child Marriage in India?

• History:
  • Historical texts suggest that early marriages were prevalent, particularly for girls, often for socio-economic reasons or to ensure family alliances.
  • During the medieval era, the practice became more entrenched due to the influence of certain religious and cultural norms. The age of marriage for girls decreased significantly, with marriages often arranged soon after puberty.
  • The British colonial government, influenced by socio-religious reformers like Raja Ram Mohan Roy and Ishwar Chandra Vidyasagar, recognized the harm of child marriage and began addressing the issue.
    • The British government introduced legislative measures to curb the practice, notably the Age of Consent Act of 1891, which raised the age of consent for marriage to 12 years.
    • The Child Marriage Restraint Act (1929), also known as the Sarda Act, set the minimum age for marriage at 14 for girls and 18 for boys, marking the first legal intervention to control child marriages.
• Status of Child Marriage in India:
  • Girl child marriages declined from 49% in 1993 to 22% in 2021. Boy child marriages reduced from 7% in 2006 to 2% in 2021, indicating an overall national decline.
  • However, between 2016 and 2021, the progress plateaued, with certain states experiencing a troubling rise in child marriages.
    • Notably, six states witnessed an increase in girl-child marriages, including Manipur, Punjab, Tripura, and West Bengal.
    • Eight states observed a rise in boy-child marriages, encompassing Chhattisgarh, Goa, Manipur, and Punjab.
• Legal Measures to Prevent Child Marriage:
  • Prohibition of Child Marriage Act (PCMA) in 2006.
  • In the case of Independent Thought v. Union of India, 2017, the Supreme Court of India held that sexual intercourse between a man and his wife, if she is aged between 15 and 18 years, constitutes rape.
    • The above judgement narrowed the scope of exception 2 to Section 375 of the Indian Penal Code (BNS) and raised the age of consent to 18 years for marital sexual intercourse.
• Government Initiatives:
  • Beti Bachao Beti Padhao scheme
  • Dhanalakshmi Scheme: It is a conditional cash transfer scheme for a girl child with insurance coverage.
    • It also aims to eliminate child marriage by offering parents insurance coverage of medical expenses and encouraging the education of the girl child.

What is the Prohibition of Child Marriage Act (PCMA) 2006?

• Objective: The Act prohibits the solemnisation of child marriages and aims to protect children from being married before the legal age.
• Legal Age for Marriage: Under the Act, the legal age for marriage is set at 18 for women and 21 for men.
• Voidable Marriages: Marriages involving minors can be declared voidable at the option of either party, and they may seek annulment within two years of attaining adulthood.
• Punishments: The Act prescribes penalties, including imprisonment and fines, for those who solemnise, conduct, or abet child marriages, as well as for parents or guardians involved.
• Child Marriage Prohibition Officers: The Act empowers states to appoint Child Marriage Prohibition Officers to prevent child marriages and ensure the law is enforced.
• Protection and Maintenance: It provides for the protection of minors involved in such marriages, including the right to maintenance for the child bride until her remarriage.
• Applicability: The Act overrides any customs, laws, or personal religious laws that allow for child marriages, ensuring universal protection across India.

What did the Court Judgement say?

• Equal Right to Childhood: The court pointed out that patriarchal ideas of masculinity and sexual dominance, along with misinformation from peers, often lead young boys to commit violence against their child brides.
  • While girls are disproportionately affected, the judgement emphasised that the right to childhood belongs to all sexes.
  • The court declared a child whose marriage was fixed as “a minor in need of care and protection” under the Juvenile Justice Act.
• Child Marriage Threatening Modern Laws: The Court noted that the centuries-old practice of child marriage undermines modern laws like the POCSO Act, 2012, as it exposes minor girls to sexual abuse despite legal protections.
• Objectification in Child Marriages: The Court held that child marriages objectify children and impose adult responsibilities, including expectations of compulsory heterosexuality and fertility.
• Disruption of Natural Sexuality: The Court noted that child marriage systematically dismantles a person’s ability to organically experience sexual desire and navigate intimacy, all under the guise of tradition.

What are the Guidelines Issued By the Court?

• Guidelines for Sexuality Education: The Court directed the government to implement age-appropriate and culturally sensitive sexuality education for children in schools.
• Child Marriage Free Village Initiative: It proposed a drive to create ‘Child Marriage Free Villages,’ akin to the ‘Open Defecation Free Village’ initiative, engaging local and community leaders in the effort.
• Online Reporting Portal: The court recommended the Home Ministry to establish a designated portal for the online reporting of child marriages.
• Compensation Scheme: The Court urged the Ministry of Women and Child Development to initiate a compensation scheme for girls who choose to exit child marriages.
• Annual Budget Allocation: It also called for the allocation of an annual budget dedicated to preventing child marriages and providing support to affected individuals.

What are the Challenges to Implement PCMA?

• Cultural Norms and Societal Attitudes: Deep-rooted cultural beliefs and practices continue to support child marriage in many communities, making it difficult to change attitudes.
  • Certain cultural and religious laws, such as Muslim personal law and tribal customs in the Northeast, permit child marriage, making the Prohibition of Child Marriage Act (PCMA) inapplicable in these cases.
  • According to the National Family Health Survey (NFHS-5) 2019-21, nearly 23% of women aged 20-24 were married before the age of 18, indicating persistent acceptance of the practice.
• Inadequate Enforcement of Laws: Despite the existence of the PCMA 2006 enforcement remains weak. Local authorities may lack the resources or commitment to take action against child marriages, resulting in low conviction rates.
• Gender Inequality: Gender-based discrimination perpetuates child marriage, as girls are often viewed as economic burdens.
• Influence of Peer Pressure: Misinformation and peer pressure among children can lead to acceptance of child marriage. Community engagement and peer education programs are necessary to counter these influences.
• Lack of Awareness and Education: Many communities lack awareness of the legal provisions against child marriage and its negative impacts.
  • Educational campaigns are needed to inform families about the benefits of delaying marriage and the rights of children.

Way Forward

• Strengthen Legal Framework and Enforcement: Enhance the enforcement of the Prohibition of Child Marriage Act by increasing the accountability of local authorities and law enforcement.
  • Establish specialised training programs for officials to effectively address and prevent child marriages.
• Expand Educational and Economic Opportunities for Girls: Invest in initiatives that promote girls' education and provide scholarships or financial support to families to keep girls in school. Eg. Nijut Moina Scheme of Assam to provide monthly financial aid to girl students from higher secondary to postgraduate levels in government and aided institutions.
  • Develop vocational training programs to empower girls economically, making early marriage less appealing.
• Strengthen Support Systems and Health Services: Establish support networks for girls at risk of child marriage, including counseling and healthcare services.
  • Provide training for healthcare providers to address the unique needs of girl child and ensure access to reproductive health services.
• Implement Comprehensive Awareness Campaigns: Launch nationwide awareness campaigns focusing on the negative impacts of child marriage and the benefits of education for girls.
  • Engage community leaders, parents, and youth to promote cultural shifts and encourage the abandonment of harmful practices.

Volcanic Eruption and Ionospheric Disturbances

Source: PIB 

Why in News? 

Recently, a new study revealed a connection between the Tonga volcano eruption and the formation of Equatorial Plasma Bubbles (EPBs) over the Indian subcontinent. 

• Tonga volcano is a submarine volcano in the South Pacific Ocean. 

What are the Key Highlights of the Study? 

• Volcanic Eruption and Space Weather: The Tonga eruption triggered ionospheric disturbances, contributing to space weather events that affect satellite signals. 
• Atmospheric Gravity Waves: The eruption produced strong atmospheric gravity waves that propagated into the upper atmosphere triggering favourable ionospheric conditions for the formation of EPBs. 
  • Atmospheric gravity waves form when buoyancy pushes air upward, and gravity pulls it back down. 
• Plasma Instabilities: Plasma blobs, an increase in the ionospheric eastward electric field at dusk were detected, indicating further ionospheric disturbances due to the eruption. 

What are Key Points about Equatorial Plasma Bubbles (EPBs)? 

• About EPBs: EPBs are ionospheric phenomena that are generated through plasma instabilities, particularly in the equatorial ionosphere. 
  • EPBs are regions of depleted plasma in the ionosphere that form near the magnetic equator during post-sunset hours. 
  • EPBs originate in the equatorial ionosphere but can extend, affecting the global ionosphere 15° North and South of the Earth's equator. 
• Impact on Radio Wave Propagation: As radio waves propagate through the ionosphere,  irregularities associated with EPBs can scatter them, leading to signal degradation. 
  • It is a major concern for communication systems that rely on high-frequency radio waves, such as satellite communications and GPS.  
• Seasonal and Regional Variability: EPBs are most frequent during the Winter solstice (21^st or 22^nd December) and least frequent during the Summer solstice (21^st June). 

What are Key Facts About the Tonga Volcano? 

• Location: It is located in the western South Pacific Ocean, west of the main inhabited islands in the Kingdom of Tonga. 
• Geology: It is one of 12 confirmed submarine volcanoes along the Tofua Arc, a segment of the larger Tonga-Kermadec volcanic arc. 
  • The Tonga-Kermadec arc formed as a result of subduction of the Pacific Plate beneath the Indo-Australian Plate. 
  • It is a part of the Ring of Fire. 
• Submarine Volcano: It is an undersea Volcano consisting of two small uninhabited islands, Hunga-Ha’apai and Hunga-Tonga.

• It reaffirmed the commitment of digitising land records under the Digital India Land Records Modernization Programme (DILRMP). 
• A pilot program named National Geospatial Knowledge-based Land Survey of Urban Habitations (NAKSHA) was introduced to create urban land records in over 100 cities/towns. 
• Use of drones and aerial photography with 3D imagery in land record creation was highlighted. 
• DILRMP (erstwhile National Land Record Modernization Programme) is a Central Sector Scheme with effect from 1st April 2016 with 100% funding by the Centre.  
  • It aims to develop a modern, comprehensive and transparent land record management system. 
  • Innovative Initiatives under DILRMP:  
    • Unique Land Parcel Identification Number (ULPIN) or Bhu-Aadhar (14 digit Alpha–numeric unique ID for each land parcel based on Geo-coordinates) 
    • National Generic Document Registration System (NGDRS) or E-Registration (to have a uniform process for registration for deeds/documents).

Recently, 28 Maoists were killed by security forces in a gunfight in Chhattisgarh’s Bastar region.

• Origin:
  • The movement originated as a rebellion against local landlords who assaulted peasants over a land dispute and is now popularly known as Maoists and referred to as Naxalites in India.
• Objective:
  • They seek to overthrow the government through armed revolution to establish a communist state based on Maoist principles, viewing the state as oppressive and addressing socio-economic grievances through armed struggle.
• Affected states:
  • The Red Corridor is the region in the central, eastern and southern parts of India that experience severe Naxalism–Maoist insurgency.
  • The States of Chhattisgarh, Jharkhand, Odisha, Bihar, West Bengal, Andhra Pradesh, Telangana, Maharashtra, Madhya Pradesh and Kerala are considered Left Wing Extremism(LWE) affected.
• Government Scheme:
  • The Niyad Nellanar Scheme: It offers amenities and benefits to villages within 5 kilometers of security camps in Bastar.
  • Security Related Expenditure (SRE) scheme: Covers security costs like training and ex-gratia to LWE-affected states.

Hyperuniformity

Source: PIB

Researchers have explored the mechanism behind the emerging property of a recently discovered exotic disordered state of matter, known as “hyperuniformity”.

• About Hyperuniformity: It is a property of certain heterogeneous media where long-wavelength density fluctuations decay to zero.
  • Hyperuniform disordered materials are observed in quasicrystals, large-scale cosmic structures, biological emulsions, and colloids.
• Mechanism Behind Hyperuniformity:
  • In hyperuniform systems, suppressed density fluctuations result from a conservation law that limits particle mobility, explaining the reduced mass fluctuations as system size grows.
• Comparison to Critical Point of Liquids:
  • Hyperuniform matter contrasts with liquid critical points, where mass fluctuations diverge and cause critical opalescence.
  • In hyperuniform matter, mass fluctuations are suppressed, positioning it between a crystal, amorphous solid, and liquid.
• Potential Applications of Hyperuniform Materials:
  • Hyperuniform materials have unique properties with potential technological and biological applications, including energy-efficient photonic devices for data transmission and controlling cellular functions.
