Why in News?

Recently, the Ministry of Women and Child Development has informed the Lok Sabha that the Protection of Children from Sexual Offenses (POCSO) Act, 2012, is one of the crucial legislations enacted by the Government to protect children from Sexual Abuse.

What is the POCSO Act?

• About:
  • POCSO Act came into effect on 14^th November 2012 which was enacted in consequence to India’s ratification of the UN Convention on the Rights of the Child in 1992.
  • The aim of this special law is to address offences of sexual exploitation and sexual abuse of children, which were either not specifically defined or in adequately penalised.
  • The Act defines a child as any person below the age of 18 years. The Act provides punishment as per the gravity of offence.
    • The Act was further reviewed and amended in 2019 to Introduce more stringent punishment including the death penalty for Committing sexual crimes on children, with a view to deter the perpetrators & prevent such crimes against children.
    • The Government of India has also notified the POCSO Rules, 2020.
• Features:
  • Gender-Neutral Nature:
    • The Act recognizes that both girls and boys can be victims of sexual abuse and that such abuse is a crime regardless of the gender of the victim.
      • This is in line with the principle that all children have the right to protection from sexual abuse and exploitation, and that laws should not discriminate based on gender.
  • Ease in Reporting Cases:
    • There is sufficient general awareness now to report cases of sexual exploitation of children not only by individuals but also by institutions as non-reporting has been made a specific offence under the POCSO Act. This has made it comparatively difficult to hide offences against children.
  • Explicit Definition of Terms:
    • The storage of child pornography material has been made a new offence.
    • Further, the offence of ‘sexual assault’ has been defined in explicit terms (with increased minimum punishment) unlike an abstract definition of ‘outraging modesty of a woman’ in the Indian Penal Code.
• POCSO Rules 2020:
  • Interim Compensation and Special Relief
    • Rule-9 of the POCSO Rules allows the Special Court to order interim compensation for the child's needs related to relief or rehabilitation after the FIR's registration. This compensation is adjusted against the final compensation, if any.
  • Immediate Payment of Special Relief:
    • Under the POCSO Rules, the Child Welfare Committee (CWC) may recommend immediate payment for essential needs like food, clothes, and transportation, using funds from the District Legal Services Authority (DLSA), the District Child Protection Unit (DCPU), or funds maintained under the Juvenile Justice Act 2015.
    • The payment must be made within a week of receiving the CWC's recommendation.
  • Support Person for the Child:
    • The POCSO Rules empower the CWC to provide a support person to assist the child throughout the investigation and trial process.
    • The support person is responsible for ensuring the child's best interests, including physical, emotional, and mental well-being, access to medical care, counseling, and education. They also inform the child and their parents or guardians about court proceedings and developments related to the case.

What are the Issues and Challenges with the POCSO Act?

• Issue with the Investigation:
  • Low Representation of Women in the Police Force:
    • The POCSO Act provides for recording the statement of the affected child by a woman sub-inspector at the child’s residence or place of choice.
    • But it is practically impossible to comply with this provision when the number of women in the police force is just 10%, and many police stations hardly have women staff.
  • Lapses in the Investigation:
    • Though there is a provision to record statements using audio-video means, however, there are still reports of lapses in the investigation and preservation of crime scenes in some cases,
      • In Shafhi Mohammad vs The State of Himachal Pradesh (2018), the Supreme Court held in cases of heinous crimes, it is the duty of the investigating officer to photograph and videograph the scene of crime and to preserve the same as evidence.
  • No Examination by Judicial Magistrates:
    • Another provision of the act mandates the recording of the statement of the prosecutrix by a judicial magistrate.
    • Though such statements are recorded in most cases, judicial magistrates are neither called for cross-examination during trial nor are those who retract their statement punished. In such a scenario, such statements get nullified.
• Issue of Age Determination:
  • Though age determination of a juvenile delinquent is guided by the Juvenile Justice (Care and Protection of Children) Act 2015 no such provision exists under the POCSO Act for juvenile victims.
    • In Jarnail Singh vs State of Haryana (2013) case, the SC held that the given statutory provision should also be the basis to help determine age even for a child who is a victim of crime.
    • However, in absence of any change in the law or even specific directions, the investigating officers (IOs) continue to rely on the date of birth recorded in school admission-withdrawal registers.
• Delays in the Filing of Charges:
  • As per the POCSO Act, the investigation of a case under the act is to be completed within a period of one month from the date of the commission of the offence, or from the date of the reporting of the offence.
  • However, in practice, the completion of investigation often takes longer than one month due to various reasons such as lack of adequate resources, delays in obtaining forensic evidence, or the complexity of the case.
• No Conditions to Prove Recent Intercourse:
  • Courts are required to presume that the accused committed the offence under the POCSO Act.
  • The POCSO Act does not impose any conditions on the prosecution, contrary to the Indian Evidence Act , which clearly requires the prosecution to establish recent intercourse, as well as the consent of the prosecutrix.
  • However, it has been observed that even after the minor age of the victim is proved, no such presumption is taken up by the court during trial.
    • Under such circumstances, the expected increase in the conviction rate is unlikely to be achieved.

Way Forward

• The government should provide adequate resources such as funding and personnel to investigating agencies handling POCSO cases. This will help to ensure that investigations are conducted in a timely and efficient manner.
• Investigating officers should be provided with proper training on the handling of POCSO cases. This can include training on the proper techniques for collecting and preserving evidence, interviewing child victims and witnesses, and the legal requirements of the POCSO Act.
• Setting up special courts for POCSO cases can help to ensure that cases are handled promptly and efficiently. This will also help to speed up the trial process, which can be important for the victim and their family.

Carbon Capture and Storage

Source: Reuters

Why in News?

The UK government has reasserted its commitment to advancing projects aimed at capturing and storing carbon dioxide (CO₂) emissions as a crucial component of its strategy to achieve net-zero emissions.

What is Carbon Capture and Storage (CCS)?

• About:
  • It is a process designed to mitigate the emissions of carbon dioxide (CO₂) generated from industrial processes and the burning of fossil fuels, particularly in power plants.
  • The goal of CCS is to prevent a significant amount of CO₂ from entering the atmosphere and contributing to global warming and climate change.
• Approaches: Carbon capture and storage (CCS) encompasses two primary approaches:
  • The first method is known as point-source CCS, which involves capturing CO2 directly at the site of its production, such as industrial smokestacks.
  • The second method, direct air capture (DAC), focuses on removing CO2 that has already been emitted into the atmosphere.
  • The recent UK initiatives specifically target point-source CCS.
• Mechanisms of Point Source- CCS: The process of carbon capture and storage encompasses several distinct steps, each contributing to the effective containment of CO₂ emissions:
  • Capture: CO₂ is isolated from other gases generated during industrial processes or power generation.
  • Compression and Transportation: Once captured, CO₂ is compressed and transported to designated storage sites, frequently through pipelines.
  • Injection: The CO₂ is then injected into subterranean rock formations, often situated at depths of one kilometer or more, where it remains stored for extended periods, sometimes lasting decades.
• Applications:
  • Mineralization: Captured carbon can be reacted with certain minerals to form stable carbonates, which can be stored safely underground or used in construction materials.
    • This process, known as mineral carbonation, offers a long-term and secure method of carbon storage.
  • Synthetic Fuels: Captured CO₂ can be combined with hydrogen (often produced via electrolysis using renewable energy) to produce synthetic fuels such as synthetic natural gas, synthetic diesel, or even synthetic jet fuel.
  • Greenhouses and Indoor Agriculture: Captured carbon dioxide can be supplied to greenhouses and indoor farming facilities to enhance plant growth.
  • Dry Ice Production: Captured carbon dioxide can be used to produce dry ice, which is solid carbon dioxide at extremely low temperatures.
    • Dry ice has various applications, including shipping and transportation of perishable goods, medical and scientific purposes, and special effects in the entertainment industry.

• Challenges:
  • Cost and Economics: CCS involves high initial capital costs for building capture, transportation, and storage infrastructure.
    • The cost of capturing CO₂ from flue gases or industrial processes can be significant, affecting the overall viability of CCS projects.
  • Geological Storage Suitability: Identifying and securing suitable geological formations for long-term CO₂ storage is a challenge.
    • Not all geological formations are appropriate for CO₂ storage due to potential risks of leakage or seismic activity.
  • Extended Lifespan of Fossil Fuel Companies: Certain environmental organizations raise concerns regarding the effectiveness of CSS, suggesting that its implementation might unintentionally prolong the operational viability of fossil fuel companies.
    • This potential consequence could inadvertently hinder the speed of transitioning to more sustainable and cleaner energy sources.

Way Forward

• Natural Climate Solutions Integration: Combining CCS with natural climate solutions can enhance its effectiveness.
  • Embracing initiatives like reforestation, afforestation, and sustainable land management can complement CCS efforts by sequestering carbon naturally, promoting biodiversity, and enhancing ecosystem resilience.
• International Collaboration and Knowledge Sharing: To address global climate challenges, countries must collaborate and share knowledge and expertise in CCS.
  • Establishing international forums, research partnerships, and technology-sharing initiatives can accelerate the development and adoption of innovative carbon capture solutions.
• Balancing CCS and Emission Reduction for Climate Action: The United Nations report underscores CCS's potential to align with the Paris Agreement’s market-based mechanisms like carbon trading through carbon credits.
  • However, it emphasizes that emission prevention remains paramount. An inclusive climate strategy mandates both carbon capture technology adoption and proactive emission reduction to effectively address climate change.
    • In line, in terms of Nationally Determined Contribution, India now stands committed to reduce Emissions Intensity of its GDP by 45% by 2030.

Excess Cane Payments

Source: IE

Why in News?

In a significant move, the Government of India has taken a step to provide relief to cooperative sugar mills by allowing them to claim excess cane price payments made to farmers as "business expenditure."

What is the Issue of Excess Cane Payments?

• Sugarcane is a major crop in India, especially in states like Maharashtra, Uttar Pradesh, Karnataka, and Tamil Nadu.
• The Centre fixes a fair and remunerative price (FRP) for sugarcane every year, which is the minimum amount that sugar mills have to pay to farmers for procuring their cane.
• However, some cooperative sugar mills, especially in Maharashtra, pay more than the FRP to farmers as an incentive or bonus. This is called excess cane payment.
• The excess cane payment has resulted in tax disputes between the cooperative sugar mills and the Income Tax Department.
  • The mills claim the excess payment as business expenditure, while the department treats it as a distribution of profits and disallows it as a deduction.

How has the Government of India Resolved the Issue of Excess Cane Payments?

• In the 2015-16 Union Budget, the Government of India introduced an amendment to the Finance Act that allowed cooperative sugar mills to claim excess cane payment as deduction for computing their business income. However, this was applicable only from the 2016-17 assessment year onwards.
• In the 2023-24 Union Budget, the Government of India extended the benefit of deduction to all financial years prior to 2015-16. This was done by amending Section 155 of the Income Tax Act .
• The move is expected to provide relief of almost Rs 10,000 crore to cooperative sugar mills, against pending tax demands and litigation in respect of payments made before the 2015-16 financial year.

What is the FRP?

• About:
  • FRP is the price set by the government that sugar mills are obligated to pay to farmers for the sugarcane procured from them.
• Payment and Agreement:
  • Mills are legally required to pay the FRP to farmers for their cane.
  • Mills can choose to sign agreements with farmers, allowing them to pay the FRP in installments.
  • Delayed payments can attract interest charges of up to 15% per annum, and the sugar commissioner can recover unpaid FRP by attaching properties of the mills.
• Governing Regulations:
  • The pricing of sugarcane is governed by the statutory provisions of the Sugarcane (Control) Order, 1966 issued under the Essential Commodities Act (ECA), 1955.
  • According to the regulations, the FRP must be paid within 14 days of cane delivery.
• Determination and Announcement:
  • The FRP is determined based on the recommendations of the Commission for Agricultural Costs and Prices (CACP).
  • The Cabinet Committee on Economic Affairs (CCEA) announces the FRP.
• Factors Considered:
  • The FRP takes into account various factors, including the cost of sugarcane production, returns from alternative crops, trends in agricultural commodity prices, availability of sugar to consumers, selling price of sugar, sugar recovery from cane, and income margins for cane growers.

What is Sugarcane?

• Temperature: Between 21-27°C with hot and humid climate.
• Rainfall: Around 75-100 cm.
• Soil Type: Deep rich loamy soil.
• Top Sugarcane Producing States: Uttar Pradesh, Maharashtra, Karnataka, Tamil Nadu, Bihar.
• India is the second largest producer of sugarcane after Brazil.
• It can be grown on all varieties of soils ranging from sandy loam to clay loam given these soils should be well drained.
• It needs manual labour from sowing to harvesting.
• It is the main source of sugar, gur (jaggery), khandsari and molasses.
• Scheme for Extending Financial Assistance to Sugar Undertakings (SEFASU) and National Policy on Biofuels are two of the government initiatives to support sugarcane production and the sugar industry.

505-Million Year Old Jellyfish Fossils

Source: TOI 

Why in News?  

Recently, researchers have unveiled a collection of jellyfish fossils from the Cambrian period, providing a unique glimpse into their distant past. 

• These preserved fossils, found in the Burgess Shale- a renowned fossil-rich site in the Canadian Rockies, offer an improbable pathway to preservation. 

What are the Major Findings of the Research?  

• Special Features of the Fossils: 
  • The newly discovered jellyfish fossils retained remarkable features, such as over 90 fingerlike tentacles protruding from their bell-shaped bodies. 
  • Some specimens even contained stomach contents and gonads, providing invaluable insights into their anatomy and behavior. 
  • These things help scientists learn about how the jellyfish looked and acted. 
• Link with Old Fossils from a Quarry:  
  • In the 1990s, scientists dug up over 170 jellyfish fossils in a place called Raymond Quarry in British Columbia. These fossils were kept for a long time. 
  • Researchers re-examined the specimens from the excavation and identified that the fossils actually belonged to a previously unknown species. 
    • This newly discovered species was named Burgessomedusa phasmiformis. The species falls under the medusozoans category. 

What are Jellyfish?  

• About:  
  • Jellyfish are members of the phylum Cnidaria, a group of animals that includes corals, sea anemones, hydroids, and siphonophores.  
    • Cnidarians are characterized by having radial symmetry, a central mouth surrounded by tentacles, and specialized stinging cells called cnidocytes that can inject venom into their prey or predators. 
  • Jellyfish tend to just follow the currents of the ocean, they can be found around the world in every type of ocean water. 
    • They are considered to be one of the earliest branches of the animal tree of life. 
• Characteristics:  
  • Despite their name, jellyfish do not have much characteristics of a fish, they are invertebrates, or animals with no backbones. 
    • Jellyfish are also among the simplest animals in terms of body organization and nervous system, lacking a brain, a heart, or a skeleton.  
  • However, some jellyfish have evolved remarkable adaptations, such as eyes, bioluminescence, and complex behaviors. 
• Prey: 
  • They dine on fish, shrimp, crabs and tiny plants. They have tiny stinging cells in their tentacles to stun or paralyze their prey before they eat them. 
• Challenge of Jellyfish Fossilization:  
  • Jellyfish, composed of 95% water, pose a considerable challenge when it comes to fossilization. Their delicate structure makes them prone to rapid deterioration, leaving behind minimal traces in the fossil record.

Ancient Giant Whale: Perucetus Colossus

The recent identification of Perucetus colossus (the colossal whale from Peru), an ancient whale species, has redefined the understanding of marine giants. A study published in Nature reveals this colossal creature's remarkable features, potentially reshaping the narrative of gigantism in marine mammals.

• The estimated skeletal mass of P. colossus exceeds that of any known mammal or aquatic vertebrate.
• The partial skeleton includes 13 vertebrae, 4 ribs, and 1 hip bone, found in Southern Peru and believed to be around 39 million years old.
• With an estimated body mass ranging between 85 and 340 tonnes and a length of 20 meters (66 feet), the newly discovered species challenges the blue whale's status as the heaviest animal. Although the blue whale remains longer, reaching over 100 feet (30 meters) in length.
• The species displays the highest degree of bone mass increase observed, associated with shallow diving.
• The trend towards gigantism in marine mammals might have originated earlier than previously believed.
