    From UPSC perspective, the following things are important:

    Prelims level: CPCB, EPR Program

    Why in the News?

    • The Central Pollution Control Board (CPCB) has started a national audit of about 800 plastic-waste recyclers across India.
      • This action follows the discovery that four firms in Karnataka, Maharashtra, and Gujarat issued nearly 600,000 fake certificates under the Extended Producer Responsibility (EPR) programme.

    About Central Pollution Control Board (CPCB): Overview

    • The Central Pollution Control Board (CPCB) is a statutory organization established in September 1974.
    • It was constituted under the Water (Prevention and Control of Pollution) Act, 1974.
    • CPCB is also entrusted with powers and functions under the Air (Prevention and Control of Pollution) Act, 1981.
    • It serves as a technical arm of the Ministry of Environment, Forests, and Climate Change, implementing the provisions of the Environment (Protection) Act, 1986.

    Principal Functions:

    • Water Pollution Control:
      • Promote the cleanliness of streams and wells in different states by preventing, controlling, and abating water pollution.
      • Oversee the National Water Quality Monitoring Program to collect, collate, and disseminate technical and statistical data relating to water pollution.

    What is Extended Producer Responsibility (EPR) Programme?

    • Extended Producer Responsibility (EPR) means the responsibility of a producer for the environmentally sound management of the product until the end of its life.
    • India had first introduced EPR in 2011 under the:
    1. Plastic Waste (Management and Handling) Rules, 2011
    2. E-Waste Management and Handling Rules, 2011.
    • The EPR scheme requires businesses using plastic packaging to recycle a certain percentage of the plastic used in the previous two years.

    Implementation of EPR:

    • Registration: Producers must register with the Central Pollution Control Board (CPCB) and submit an EPR plan.
    • Collection Mechanisms: Producers set up collection centers, return schemes, or partner with authorized recyclers to manage waste.
    • Documentation: Producers are required to maintain detailed records of waste collected and processed and submit regular reports to the CPCB.
    • Compliance Audits: The CPCB conducts audits to ensure that producers comply with EPR requirements.

    Function of EPR Certificates:

    • Registered plastic waste recyclers generate EPR certificates by recycling plastic waste.
    • Every tonne of plastic recycled generates a certificate.
      • According to a CPCB report in May, nearly 3.7 million tonnes of recycled plastic generated certificates.
    • In 2022-23, about 18,000 companies using plastic packaging were registered with the CPCB, aiming to recycle about 3.3 million tonnes.

    Compliance and Targets:

    • Companies must recycle 70% of the packaging used in the previous two financial years for 2022-23 and 100% for 2023-24. Non-compliance with these targets can result in fines.

    Bombay HC quashes Exemption from RTE Quota for Private Schools  

    Prelims Only | Polity | Mains Paper 2: Indian Constitution – historical underpinnings, evolution, features, amendments, significant provisions and basic structure

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Features of the RTE Act

    Why in the News?

    The Bombay High Court has cancelled the Maharashtra government’s new rule that allowed private schools within 1 kilometer of government or government-aided schools to avoid reserving 25% of their seats for students from weaker sections and disadvantaged groups.

    Right to Education (RTE) Act: Overview

    • The Right to Education (RTE) Act, 2009 ensures free and compulsory education as fundamental right under Article 21A of the Indian Constitution.
    • It mandates that every child has the right to full-time elementary education of satisfactory and equitable quality in a formal school that meets certain essential norms and standards.
    • Key Provisions:
      • The RTE Act provides for free and compulsory education for all children between 6 and 14 years.
      • Schools must be available within a prescribed distance from the child’s residence to ensure accessibility.
      • The Act ensures the provision of adequate teachers and the establishment of standards for their training and quality.
    • Teacher Qualification: The teacher must pass the Teacher Eligibility Test (TET), which is administered by the respective government authority. The National Council for Teacher Education (NCTE) has established the minimum qualifications required for a person to be eligible for appointment as a teacher for classes I to VIII.
    • The RTE Act does NOT apply to Minority institutions.

    Section 12(1) (C) of the RTE Act:

    • Section 12(1) (C) requires private unaided and specified category schools to reserve at least 25% seats for children from economically weaker sections and disadvantaged groups.
    • This provision aims to promote social inclusion and ensure that children from all backgrounds have access to quality education.
    • The government reimburses schools for the expenses incurred for admitting these children, based on per-child expenditure incurred by the state.
    • Children from economically weaker sections and disadvantaged groups benefit from this Section as it provides them access to private schooling.
    • This section aims to contest education apartheid and bring parity and equality of opportunity for all children.

    Details of the Exemption Rule in Maharashtra

    • The notification stated that private unaided schools within one kilometer of a government or government-aided school would not need to reserve 25% of seats for socio-economically backward students.
    • Students in these areas would first be considered for admission to nearby government or government-aided schools.
    • The exemption also applied to future private schools established within a one-kilometer radius of government or government-aided schools.
    • If no such schools existed in the vicinity, private schools would be identified for RTE admissions.

    Similar Exemptions in Other States

    • Maharashtra joined Karnataka and Kerala in implementing this regime to exempt private schools from RTE admissions.
    • Karnataka introduced the rule in December 2018, referencing Kerala’s rules introduced in 2011.
    • In Kerala, the fee concession is available to RTE quota students only if there are no government or aided schools within one kilometer for Class 1 students.

    Reasons for Introducing Exemptions

    • Karnataka’s Law Minister stated in 2018 that the primary intention of RTE is to provide education to all classes of students.
    • Allowing parents to admit children to private schools despite nearby government schools resulted in a drop in enrollment ratios in government schools.
    • Private schools and teachers’ organizations highlighted that state governments often failed to reimburse fees for students admitted through the RTE quota.
      • Section 12(2) of the RTE Act binds state governments to reimburse expenses incurred by schools per child or the fee amount, whichever is less.
      • In Maharashtra, the Maharashtra English School Trustees Association (MESTA) threatened to boycott RTE admissions last December due to pending reimbursements of Rs 1,800 crore.

    PYQ:

    [2022] The Right of Children to Free and Compulsory Education Act, 2009 remains inadequate in promoting incentive-based systems for children’s education without generating awareness about the importance of schooling. Analyse.

    [2018] Consider the following statements:

    1. As per the right to education (RTE) Act, to be eligible for appointment as a teacher in a state, a person would be required to possess the minimum qualification laid down by the concerned State council of Teacher education.
    2. As per the RTE Act, for teaching primary classes, a candidate is required to pass a Teacher Eligibility Test conducted in accordance with the National Council of Teacher Education guidelines.
    3. In India, more than 90 % of teacher education institutions are directly under the State Governments.

  • Tribes in News

    Bhil Tribe have again demanded a separate ‘Bhil Pradesh’

    Prelims Only | Indian Society | Mains Paper 1: Communalism, Secularism, Regionalism

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Bhil Tribe

    Why in the News?

    A large number of people from the Bhil tribe recently gathered at a rally in Rajasthan’s Mangarh Dham to raise the demand for an independent ‘Bhil state’.

    Background of the Bhil Pradesh Demand

    • The idea of a tribal state, comprising parts of Rajasthan, Madhya Pradesh, Gujarat, and Maharashtra, has been discussed previously.
    • The demand for a separate tribal state in western India was put forward by the Bharatiya Tribal Party (BTP) formed in 2017.
    • The Bhil community has been demanding that 49 districts be carved out of the four states to establish Bhil Pradesh.
    • The demand for Bhil Pradesh has been raised repeatedly since Independence.

    Historical Context

    • Bhil social reformer and spiritual leader Govind Guru first raised the demand for a separate state for tribals in 1913.
    • The demand followed the Mangarh massacre, where hundreds of Bhil tribals were killed by British forces.
    • The massacre took place six years before the Jallianwala Bagh massacre and is sometimes referred to as the “Adivasi Jallianwala”.

    Reasons for the Demand

    • Earlier, the tribal-majority regions were a single entity but were divided post-Independence.
    • According to the 2011 census, tribals comprise almost 14% of Rajasthan’s population.
    • Several Union governments have brought various laws and schemes for tribals but have been slow in implementation.

    Example of Implementation Issues

    • The Provisions of the Panchayats (Extension to Scheduled Areas) Act, 1996, aimed to decentralize governance and empower gram sabhas in tribal areas.
    • The Rajasthan government adopted the law in 1999, but its rules were only formulated in 2011.
    • Many people, including local leaders, are still unaware of the law.

    Prelims level: MISA, Implications of Emergency

    Why in the News?

    • Prithipal Singh Randhawa, leader of the Punjab Students Union (PSU), was murdered in Ludhiana on July 18, 1979.
      • At the time of his death, he was 27 years old and among the most prominent leaders of the student union movement in Punjab during the 1970s.

    Who was Prithipal Singh Randhawa?

    • Randhawa hailed from Hoshiarpur in Punjab and joined Punjab Agricultural University (PAU), Ludhiana, in 1972.
    • On October 5, 1972, students protested outside Regal Cinema in Moga district against black marketing of tickets. 
      • The police opened fire, killing four people, including student leaders Swarn Singh and Harjeet Singh.
    • In response, Randhawa launched a mass movement, leading to the arrest of the responsible police officers.
    • On October 26, 1974, he organized the massive Moga Sangram rally, addressing issues like student fee hikes and the United States’ imperial war in Vietnam.
    • He was assassinated on July 18, 1979, after abduction.
    • His rising popularity and anti-establishment stance led to his arrest and 19-month imprisonment under the Maintenance of Internal Security Act (MISA) during the Emergency.
    • His death led to massive protests in Punjab, Haryana, and Delhi.

    Back2Basics: Maintenance of Internal Security Act (MISA): Overview

    • The MISA was a controversial law enacted by the Indian government in 1971.
    • It was primarily aimed at ensuring internal security and public order during times of political unrest and emergencies.
    • MISA was heavily used during the Emergency period (1975-1977) declared by Prime Minister Indira Gandhi.

    Key Provisions:

    • Preventive Detention: MISA allows for the preventive detention of individuals without trial for a maximum period of two years. This was intended to pre-emptively address threats to national security.
    • Detention without Charges: Individuals could be detained without being charged with a specific offense, based on the suspicion of being a threat to national security or public order.
    • No Right to Legal Representation: Detainees under MISA did not have the right to legal representation or a fair trial.
    • Limited Judicial Review: The act severely restricted the scope of judicial review, making it difficult for courts to intervene in cases of detention under MISA.

    Controversy and Criticism:

    • Human Rights Violations: MISA was widely criticized for its draconian measures and violation of fundamental human rights, including the right to liberty, freedom of speech, and due process.
    • Political Repression: The act was seen as a tool for political repression, used by the government to silence opposition and dissent.
    • Abuse of Power: There were numerous instances of abuse of power under MISA, with individuals being detained on vague or politically motivated grounds.

    Repeal:

    • After the end of the Emergency in 1977, the newly elected Janata Party government repealed MISA in 1978 as part of its efforts to restore democratic norms and civil liberties.
    • The legacy of MISA remains a stark reminder of the potential for misuse of power and the importance of safeguarding democratic principles and human rights.

  • Capital Markets: Challenges and Developments

    Decline in popularity of Equity Linked Savings Schemes (ELSS)

    Prelims Only | Economics | Mains Paper 3: Indian Economy

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Equity Linked Savings Schemes (ELSS); Section 80C of the Income Tax Act.

    Why in the News?

    • Equity Linked Savings Schemes (ELSS) are mutual fund schemes that offer tax benefits under Section 80C of the Income Tax Act.
      • Recently, ELSS has seen a decline in popularity, with more money being withdrawn from these schemes than invested.

    What is Section 80C of the Income Tax Act?

    • Section 80C permits certain investments and expenses to be tax-exempted.
    • By well-planning the 80C investments that are spread diversely across various options like National Savings Certificate (NSC), Unit Linked Insurance Plan (ULIP), Public Provident Fund (PPF), etc., an individual can claim deductions up to Rs 1,50,000.
    • By taking tax benefits under 80C, one can avail of a reduction in tax burden.

    About Equity Linked Savings Schemes (ELSS)

    • An ELSS fund or an equity-linked savings scheme is the only kind of mutual funds eligible for tax deductions under the provisions of Section 80C of the Income Tax Act, 1961.
    • Investors can claim a tax rebate of up to Rs 1,50,000 and save up to Rs 46,800 a year in taxes by investing in ELSS mutual funds.
    • ELSS mutual funds’ asset allocation is mostly (65% of the portfolio) made towards equity and equity-linked securities such as listed shares.
    • They may have some exposure to fixed-income securities as well.
    • These funds come with a lock-in period of 3 years only, the shortest among all Section 80C investments.
    • Being market-linked, they are subject to market risk, but may offer potentially higher returns compared to traditional tax-saving instruments like National Savings Certificate (NSC) or Public Provident Fund (PPF).

    Recent Trends in ELSS

    • In the past few months, more money has been taken out of ELSS than put in.
    • For example, last month ₹445 crore was withdrawn, while in April it was ₹144 crore.
    • In the last fiscal year, only ₹1,041 crore was invested in ELSS, compared to ₹7,744 crore the previous year.

    Impact of the New Tax Regime

    • A new tax regime was introduced in 2020-21, which is now the default option.
    • The old tax regime offered various tax exemptions and deductions, helping to reduce income tax.
    • These benefits are not available under the new tax regime, making ELSS less attractive to investors.

    • It is roughly 45 meters wide and up to 80 meters long, with an area equivalent to 14 tennis courts.

    Research Method

    • Researchers analyzed photos taken in 2010 by NASA’s Lunar Reconnaissance Orbiter (LRO) spacecraft.
    • They concluded that the pit was the entry point to a cave created by the collapse of a lava tube, a tunnel formed when molten lava flows beneath a field of cooled lava.

    Back2Basics: Lunar Reconnaissance Orbiter (LRO) 

    • NASA launched the LRO on June 18, 2009.
    • LRO’s primary mission is to map the Moon’s surface in high detail to identify safe landing sites and locate potential resources.
    • It is equipped with seven scientific instruments, including a camera, a laser altimeter, and a radiation detector.
    • LRO has provided critical data on lunar topography, temperature, and radiation levels, significantly enhancing our understanding of the Moon.

    Characteristics of Lunar Caves

    • Craters are bowl-shaped and result from asteroid or comet strikes.
    • Pits, in contrast, appear as massive steep-walled depressions.
    • At least 200 such pits have been discovered, with 16 believed to have formed from collapsed lava tubes due to volcanic activity over a billion years ago.

    Benefits for Human Exploration

    • The Moon is exposed to solar radiation 150 times stronger than Earth.
    • The lunar surface heats to about 127 degrees Celsius during the day and cools to around -173 degrees Celsius at night.
    • Caves, however, maintain stable average temperatures of around 17 degrees Celsius.
    • They could shield human explorers from radiation and micrometeorites, making them viable for future lunar bases or emergency shelters.

    Challenges and Further Research

    • The depth of such caves could present challenges for accessibility.
    • There are risks of potential avalanches and cave-ins.

    Need for Further Research

    • Further research is needed to understand and map the structural stability of the caves.
    • This could be done using ground-penetrating radar, robots, or cameras.
    • To become viable habitats, caves would need systems to monitor movement or seismic activity and safety zones for astronauts in case of a cave collapse.

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Python Farming

    Why in the News?

    • In the farmlands of central Thailand, thousands of pythons are raised in a warehouse for their diamond-patterned skins, which are sold to high-end European fashion houses.
      • Some scientists and industry insiders believe the true value of these snakes lies in their meat.

    Python Farming in Asia

    • Researchers estimate that China and Vietnam alone have at least 4,000 python farms, producing several million snakes primarily for the fashion industry.
    • A study published in Nature highlighted python farming as a flexible and efficient response to global food insecurity.

    Benefits of Python Farming

    • Pythons can survive for months without food or water and maintain their condition.
    • They were fed waste chicken and wild-caught rodents, offering a more efficient feed-to-meat ratio than poultry, beef, and even crickets.
    • Female pythons can lay between 50 and 100 eggs annually, leading to rapid reproduction.

    Advantages of Python Meat

    • Pythons offer a more efficient feed-to-meat ratio than poultry, beef, and even crickets.
    • They can survive without food and water for months without losing condition.
    • Python meat has a chicken-like texture and is low in saturated fats.
    • It could provide a sustainable protein source with a lower environmental impact compared to traditional meat.

    Challenges and Market Acceptance

    • Despite the advantages, the market is limited for python meat.
    • Python farmers struggle to convince people to consume snake meat, resulting in most of it being discarded or sold to fish farms.

    Environmental Impact of Traditional Meat

    • The UN’s IPCC notes that meat from grazing animals has the greatest environmental impact.
    • The climate impact of traditional meat is significant, with beef identified as having the greatest environmental impact.
    • The UN and climate activists advocate for a more plant-based diet, but the demand for meat is expected to increase by 14% by 2032.
    • Drought and extreme weather are making traditional farming difficult in many parts of the world, increasing the need for alternative protein sources.
    • The paradox of rising meat demand and environmental concerns has spurred interest in alternatives like edible insects and lab-grown meats.

    Python Meat as an Alternative

    • Protein-energy malnutrition caused nearly 190,000 deaths globally in 2021, emphasizing the urgent need for protein sources in many parts of the world.
    • Python meat could help address this issue, offering a sustainable and efficient alternative.

     

    PYQ:

    [2018] How far do you agree with the view that the focus on lack of availability of food as the main cause of hunger takes the attention away from ineffective human development policies in India?
