The Paradox of BRICS: Prospects for Expansion and Internal Imbalance

Mysterious are the ways in which multilateral groupings prosper and wither away. The case of BRICS grouping is truly remarkable. Despite initial achievements, BRICS has started losing its sparkle due to various global and regional challenges. However, the paradox lies in the fact that numerous nations are eager to join the group, showcasing the continuing appeal of BRICS.

Origins and Evolution of the BRICS

  • The term BRIC was coined in 2001 by economist Jim O’Neill in a research study that identified Brazil, Russia, India, and China as rising economies with high growth potential.
  • BRIC formalisation: The first formal meeting of BRIC leaders occurred in 2009 on the margins of the G20 Summit in Russia, establishing the group as a platform for collaboration and debate.
  • South Africa was invited to join BRIC in 2011, increasing the group’s name to BRICS. China lobbied for South Africa’s admission, seeking larger representation in Africa and diversifying the group.
  • Economic Focus: Initially, BRIC was largely an economic grouping, emphasising these countries’ growing significance in the global economy as a result of their big populations, vast territories, and strong economic growth rates.
  • Geopolitical collaboration: BRICS has expanded over time to encompass geopolitical collaboration and shared viewpoints on global issues. Leaders began talking about politics and calling for a more equitable world order.
  • Annual Summits: BRICS began having annual summits when leaders from member nations assemble to debate and coordinate their stances on different global concerns, as well as to explore opportunities for cooperation.

Key achievements of the BRICS

  • Economic Cooperation: The BRICS initiative has encouraged economic cooperation among member countries, resulting in increased trade, investment, and business prospects. The group has developed initiatives to promote economic growth and development by expanding trade and investment relations.
  • New Development Bank (NDB): BRICS founded the New Development Bank, often known as the BRICS Bank, to give financial assistance to member nations and other emerging economies for infrastructure projects and sustainable development programmes. The NDB has made considerable investments in a variety of initiatives, assisting with infrastructure development and regional connections.
  • The Contingent Reserve Arrangement (CRA) is a financial mechanism developed by the BRICS to offer liquidity support during times of financial stress and to protect against global liquidity pressures. This agreement has assisted member countries in mitigating possible financial crises and improving financial stability.
  • Geopolitical Influence: BRICS has projected a non-western stance on global and regional issues, bolstering the world’s march towards multipolarity and limiting the West’s dominance. The group has established consensus perspectives on a wide range of global issues, including climate change, terrorism, and global governance reform.

Internal Imbalance and BRICS Challenges

  • Diverse Economic Systems: BRICS member countries have a range of economic systems, from state-controlled to market-based. These economic model variances can lead to differences in policy priorities, approaches to trade and investment, and economic issues, perhaps causing friction within the group.
  • Differences in Political Systems and Governance: The BRICS countries have diverse political systems and governance frameworks. While some members respect democratic ideas, others view governance and human rights differently. These distinctions can lead to diverse opinions on political and human rights concerns, thereby complicating efforts to reach consensus on specific topics.
  • Economic Vulnerabilities: BRICS member countries are vulnerable to economic vulnerabilities such as structural concerns, external shocks, and commodity price variations. Economic issues such as high inflation, fiscal imbalances, and currency instability can put a strain on the BRICS’ economic cooperation and stability.
  • Differences in Political Systems and Governance: The BRICS countries have diverse political systems and governance frameworks. While some members respect democratic ideas, others view governance and human rights differently. These distinctions can lead to diverse opinions on political and human rights concerns, thereby complicating efforts to reach consensus on specific topics.
  • Economic Vulnerabilities: BRICS member countries are vulnerable to economic vulnerabilities such as structural concerns, external shocks, and commodity price variations. Economic issues such as high inflation, fiscal imbalances, and currency instability can put a strain on the BRICS’ economic cooperation and stability.
  • Coordination and Decision-Making Processes: BRICS is a consensus-based organisation that requires member countries to agree on a variety of problems. Coordination and decision-making can be difficult due to member countries’ various interests, agendas, and institutional structures. Consensus on crucial issues can be time-consuming and difficult.
  • Institutional Development: Effective governance structures, operational frameworks, and decision-making procedures are required for BRICS institutional development, such as the New Development Bank and the Contingent Reserve Arrangement. Creating and managing these institutions while addressing the different requirements and interests of member countries can be difficult.

The BRICS countries’ desire for expansion

  • Global Influence: Many countries regard BRICS as a prominent grouping with global clout. Joining BRICS will allow countries to increase their global influence and have a say in determining global priorities.
  • Economic Opportunities: The BRICS countries account for a sizable share of the world’s population and GDP. Joining the group might provide countries with access to a big market as well as enhanced economic cooperation, including trade and investment opportunities among members.
  • Limited options: Some nations may perceive BRICS as an appealing choice for collaboration and participation, especially if they have limited options to join other large multilateral groups or regional blocs.
  • South-South Cooperation: The BRICS countries are viewed as a platform for South-South cooperation, fostering conversation and collaboration among countries in the Global South. Joining BRICS allows countries to enhance ties with like-minded countries and contribute to a collective voice for developing countries’ concerns.
  • offset to Western Influence: The drive for BRICS expansion may also originate from a desire to offset Western nations’ domination in global affairs. Countries may want to associate themselves with BRICS in order to reflect a non-western worldview and lobby for a more fair international order.

Prospects for expansion of BRICS and the criteria for new member admission

Prospects for Expansion:

  • A increasing number of countries are interested in joining BRICS, showing the group’s recognised importance and popularity.
  • As of present, 19 nations have shown interest in joining BRICS, including Argentina, Egypt, Indonesia, the United Arab Emirates, and Bangladesh.
  • The ambition to increase global influence, the fear of missing out on membership in a prominent group, restricted alternatives for joining other groups, and the desire to build a significant platform for the Global South all contribute to the drive to expand.

Admission Criteria for New Members

  • Economic Size and Potential: Potential new members should have a sizable and rising economy that can contribute to the group’s economic strength and cooperation.
  • Regional participation: BRICS has aspired for diversified regional participation, as evidenced by the inclusion of South Africa as Africa’s representative. New members may be considered based on regional representation and the intention to ensure a greater geographic breadth.
  • Political Stability and Compatibility: Political stability and compatibility with BRICS ideals and principles, such as democracy, human rights, and governance, may be crucial factors in accession.
  • Prospective members should demonstrate a real commitment to international cooperation, multilateralism, and the BRICS principles and aims.
  • Mutual Benefits: The admission of new members should benefit both present and prospective members, contributing to increased economic cooperation, geopolitical influence, and the fulfilment of joint goals.
  • Consensus Among Existing Members: The existing BRICS member countries’ agreement would be critical in determining the admission of new members. Existing members would have to agree on the enlargement and which nations would be accepted.

The BRICS Future: Key Aspects

  • Economic Cooperation: The BRICS group has the ability to strengthen economic cooperation and promote intra-BRICS trade and investment. Member nations can explore new areas of economic cooperation, such as digital economy, technology, sustainable development, and infrastructure investment, by utilising their collective market size and resources.
  • Institutional Development: BRICS built major institutions such as the New Development Bank (NDB) and the Contingent Reserve Arrangement (CRA). The group may concentrate on further enhancing and expanding the role of these institutions in addressing financial difficulties and supporting long-term development projects.
  • Member countries can enhance their collective voice and influence international dialogues and decision-making processes by coordinating their stances on global governance, security, and geopolitical problems. BRICS can also promote South-South cooperation and advocate for developing countries’ interests in global forums.
  • Expansion and Outreach: Other countries’ interest in joining the BRICS gives a chance for expansion and outreach. The group can carefully assess new member admission, ensuring that the expansion is consistent with the group’s aims, ideals, and standards. BRICS can extend its geographic coverage and potentially improve its collective power by welcoming new members.
  • Cooperation in Innovation and Technology Member countries can work together on artificial intelligence, renewable energy, space exploration, and digital governance, among other things. Sharing experience, research, and best practises can help the organisation improve technologically and create mutual growth.
  • Adaptation to Global Challenges: The BRICS countries should work together to solve global issues such as climate change, public health crises, and sustainable development. The group can help identify solutions and shape global agendas on crucial issues by coordinating efforts, sharing knowledge, and pooling resources.

@the end

The paradox of BRICS is that it is losing its attraction while drawing a large number of nations willing to join. Despite internal strife, the BRICS have made major contributions to global multipolarity and economic cooperation. BRICS may continue to play an important role in creating the international order and advancing the interests of emerging economies and the Global South by addressing internal imbalances, seizing chances for growth, and remaining sensitive to global dynamics.

PARAKH Programme

  • The Ministry of Education has convened a workshop in New Delhi to explore the consolidation of 60 school examination boards operating in various states and union territories.
  • PARAKH, the National Assessment Centre established by the National Council of Educational Research and Training, is a critical component of this plan.

What is PARAKH?

  • PARAKH is an acronym that stands for Performance Assessment, Review, and Knowledge Analysis for Holistic Development.
  • It is a non-profit organisation formed to bring together educational boards from various states and union territories on a single platform.
  • It was launched as part of the National Education Policy (NEP)-2020 implementation.

It functions as an NCERT constituent unit.

  • It is responsible for administering periodic learning outcome examinations such as the National Achievement Survey (NAS) and State Achievement Surveys.
  • It will focus on three important areas of assessment: large-scale assessments, school-based assessments, and examination reforms.

The following are the primary goals of the PARAKH

  • Uniform Norms and Guidelines: In all recognised school boards, thorough norms, standards, and procedures for student assessment and evaluation are established.
  • Improve the Assessment Pattern: Encourage school boards to implement assessment systems that are linked with 21st-century skill standards.
  • Reduce Evaluation Disparity: Creating consistency between state and central boards, which now use varied evaluation criteria, resulting in considerable score differences.
  • Benchmark Assessment: Creating a benchmark assessment system to shift away from rote learning and comply with the NEP 2020 objectives.

Outcomes of the recent workshop

(1) Establishing Equivalence of Boards

  • The Centre is preparing towards board equivalency to allow students to move seamlessly between boards or regions.
  • The goal is to improve the authenticity and recognition of certificates and grades gained across boards by aligning curriculum standards, grading systems, and evaluation procedures.

(2) Moving away from Rote Examination Culture

  • The programme emphasised the importance of rethinking the current rote examination culture in the educational system.
  • There is a growing recognition that holistic assessments that take into account all aspects of a student’s abilities and potential are equally significant.

(3) Standardization and Fairness in Assessments

  • The importance of well-designed and standardised question papers in ensuring fairness and consistency across schools and boards was emphasised during the discussion.
  • Finding a happy medium between formative and summative assessments was found as a way to alleviate the strain of high-stakes exams while accurately monitoring student progress.

@the end

PARAKH’s significance stems from its ability to effect transformative change by encouraging collaboration and benchmarking assessments.

It is a vital step towards developing a standardised and equitable evaluation system that will provide students with a level playing field on which to demonstrate their abilities and capabilities.

Antarctic Sea Ice Coverage at a Record Low

For the second year in a row, Antarctic sea ice hit the smallest area on record in February, continuing a decade-long decrease.

Key data on ice cover decline

(1) Square km decline

  • The figures were published by the European Union’s Copernicus Climate Change Service (C3S), which highlighted the dramatic decline in Antarctic sea ice.
  • The ice-covered ocean area around Antarctica dropped to 2.09 million square kilometres (800,000 square miles) on February 16, the lowest level since satellite records began.

(2) Warming trends

  • Temperatures at both the North and South poles have risen by around 3 degrees Celsius compared to late-nineteenth-century values, which is three times the global average.
  • Since the late 1970s, Arctic sea ice has been shrinking by roughly 3% each year, while Antarctic sea ice has been relatively steady with substantial yearly changes.

(3) Regional variances and vulnerabilities

  • The recent decline in ice cover during the southern hemisphere summer has been particularly noticeable in West Antarctica, which is more vulnerable to the effects of global warming than East Antarctica.
  • In 2020, Antarctica experienced its first heatwave, with temperatures 9.2 degrees Celsius above the average maximum. Temperature spikes that are out of the ordinary have been seen in several locations of Antarctica.
  • The Arctic has also seen major losses in sea ice, with 2012 setting a new low for minimum sea ice extent.

The Effects of Declining Ice Coverage

  • Melting ice in Antarctica leads to rising sea levels across the planet.
  • Ecosystem disruption: Reduced ice cover impacts habitats and food sources for ice-dependent organisms.
  • Increased warming: Because less ice reflects sunlight, more heat is absorbed and more ice melts.
  • Ocean circulation changes: Declining ice cover can disrupt currents and have an impact on global climate patterns.
  • Melting ice releases trapped carbon, which may have an impact on marine ecosystems and contribute to climate change.
  • Amplification of global warming: The loss of ice cover produces a positive feedback loop that accelerates climate change.
  • Changes in ice conditions have an influence on species that rely on ice algae, as well as the wider Southern Ocean environment.

Forecasts for the future

  • The Intergovernmental Panel on Climate Change (IPCC) estimated that by mid-century, the Arctic Ocean would be nearly ice-free in September at least once.
  • The declining trends in Arctic and Antarctic sea ice underline the critical importance of addressing climate change and its impact on the Polar Regions.

A study reveals a distinct Nervous System in Comb Jellies

  • Comb jellies, also known as ctenophores, are sea creatures with jelly-like bodies and iridescent combs.
  • They are an old animal lineage with their own neurological system.
  • A recent study published in Science looked at the neurological system of comb jelly and made some interesting findings.

What exactly are Comb Jellies?

  • Ctenophores, or comb jellies, are marine creatures that belong to the phylum Ctenophora. They are enthralling creatures with a distinct and delicate appearance.
  • Contrary to popular belief, comb jellies are not genuine jellyfish.
  • They have a gelatinous, translucent body that is typically luminous and ornamented with rows of cilia, or comb-like features that give them their distinctive shimmering appearance.

Results of the new study

  • The researchers wanted to look into how nerve net neurons link in comb jellies.
  • Synapses (junctions between neurons) were not present in the nerve net, contrary to predictions.
  • Instead, nerve-net neurons were linked together indefinitely by a single plasma membrane.

Significance of ctenophores

  • Electron microscopy proved the separate-cell nature of neurons connected by synapses in the 1950s.
  • Ctenophores, as discovered in the present study, challenge this concept by having a syncytial nerve net.
  • Ctenophores drew attention since they were thought to be an early animal lineage.
  • Whole-genome sequencing research backs up the idea that ctenophores diverged early in animal evolution.

Ctenophore nervous systems evolve

  • Biologists are still puzzled about the evolution of ctenophore neural systems.
  • Leonid Moroz offered a contentious idea of ctenophores’ and other animals’ separate nervous system evolution.
  • Ctenophores have a distinct neural system that lacks traditional neurotransmitter routes and common neuronal genes.
  • The lack of muscular movement and reliance on cilia may have led to the evolution of a distinct signal conduction mechanism.

Further research questions

  • The researchers hope to learn more about the formation of nerve net neurons in ctenophores.
  • They want to know if adult ctenophores keep their syncytial nerve nets or acquire synapses.
  • The peculiarity of ctenophore neural systems provides vital insights into nervous system evolution.
  • Comparative studies of unusual animal systems, such as ctenophores, help to understand neural function and treat problems.

Conclusion

  • More research is needed to understand the functional and evolutionary importance of syncytial nerve net neurons in ctenophores.
  • This research lays the groundwork for future research on the evolution of neural systems in animals.
  • Comparative research on microscopic marine animals such as ctenophores reveal fundamental aspects of brain function.

Anxious Decline in Antarctic Sea Ice: A Sign of Global Concerns

The recent record-breaking decline in Antarctic Sea ice extent on February 19 has sparked serious worries about global warming’s effects. This concerning trend, combined with rising global temperatures, endangers coastal cities and has far-reaching implications for weather patterns and undersea ecosystems. As sea ice melts and global sea levels rise, immediate action is required to address the environmental concerns that this worrisome reduction presents.

Melting Sea Ice and Rising Sea Levels: A worrying trend

  • The Antarctic Sea ice cover has shrunk significantly during the last six years, causing global sea levels to rise.
  • According to NASA, meltwater from Antarctic ice accounts for around one-third of global average sea level rise since 1993.
  • The extent of sea ice in 2023 has frequently been significantly lower than that witnessed in 2022, which had the second-lowest summer sea ice extent in Antarctica.
  • The Antarctic Sea ice extent on May 21, 2023, has fallen drastically compared to the 1981–2010 median extent.
  • The Antarctic region’s April temperature in 2023 was 0.93°C higher than the 1910-2000 average for that month, the second-highest rise in the millennium.

Impact of Antarctic Sea Ice Decline on Global Weather and Ecosystems

  • Weather Pattern Alterations: The Southern Ocean, which surrounds Antarctica, is critical in transmitting heat from the atmosphere to the world’s oceans. As Antarctic sea ice melts, it introduces cold, fresh water into the ocean, upsetting global circulation patterns of hot, cold, fresh, and salty water. This change in temperature and density can have an impact on weather patterns such as wind patterns, precipitation, and storm formation.
  • Marine Currents and Nutrient fluxes: As sea ice melts, changes in water temperature and density can disrupt marine currents and nutrient fluxes. These currents are essential for transporting heat, nutrients, and oxygen across the world’s seas. The disruption of these fluxes can have a cascading effect on marine ecosystems, affecting nutrient distribution and availability for numerous animals.
  • Underwater Ecosystem Impact: Sea ice provides an important habitat for a variety of creatures, including algae, krill, and other marine life. Reduced sea ice affects food availability and disrupts the eating patterns and reproduction cycles of organisms that rely on these environments. This disruption has the potential to have a huge impact on the entire Antarctic food chain, harming animals such as whales, seals, penguins, and seabirds.
  • Altered Albedo Effect: As sea ice coverage declines, the Earth’s albedo effect decreases. The ability of a surface to reflect sunlight back into space is referred to as albedo. Sea ice has a high albedo, which means it reflects a large part of incoming solar radiation. Darker ocean water absorbs more solar energy when sea ice melts, increasing warmth and aggravating the overall warming trend.
  • Loops of Feedback: Melting sea ice creates feedback loops that amplify the effects of climate change. For example, as sea ice melts, the ocean absorbs more heat, speeding up the melting process. These feedback loops lead to the intensification of warming trends and accompanying environmental changes.

Rising Sea Levels’ Impact on Coastal Communities Around the World

  • Flooding and erosion are becoming increasingly common as sea levels rise, making coastal communities more vulnerable to storm surges, high tides, and extreme weather events. This increases the risk of inundation, property destruction, and relocation of populations in low-lying areas, including coastal cities and communities.
  • Coastal Infrastructure Vulnerability: Increased floods and erosion can cause vital infrastructure to deteriorate and fail, interrupting transportation, energy supply, and important services. This vulnerability can have serious economic, social, and public safety consequences.
  • Rising sea levels can penetrate freshwater sources and contaminate subsurface aquifers, particularly in coastal areas where freshwater and saltwater interfaces exist. This saltwater intrusion can jeopardise drinking water supplies, agricultural irrigation, and ecosystems that rely on freshwater resources, worsening water scarcity challenges.Community Displacement: As coastal areas become uninhabitable owing to sea-level rise and increased floods, communities may be compelled to relocate. This relocation can result in the loss of homes, cultural heritage, and livelihoods, causing social turmoil, economic hardships, and psychological effects on those affected.
  • Coastal ecosystems, such as mangroves, coral reefs, and wetlands, provide essential habitat, act as a buffer against storms, and maintain biodiversity. Rising sea levels have the potential to inundate and damage these ecosystems, resulting in the loss of vital ecological services, greater vulnerability to coastal hazards, and decreased coastal resilience.
  • Economic Consequences: Sea-level rise and coastal flooding can damage the tourism, fishing, and shipping industries, resulting in economic losses, employment dislocation, and lower productivity. Furthermore, the expenses of coastal protection and infrastructure adaptations to increasing sea levels can place a major strain on local economies and governments.

Ways to Strengthen International Cooperation

  • Collaborate at global forums to address climate change and its impact on Antarctica, emphasising the importance of reducing emissions and adopting sustainable practises.
  • Increased Monitoring and Research: Invest in further research to better understand the dynamics of melting sea ice, the effects on ecosystems, and viable mitigation solutions.
  • Promoting Sustainable Practises: To reduce human effect on the fragile Antarctic ecosystem, encourage sustainable practises and responsible tourism in the Antarctic region.
  • Climate Resilience Planning: Create strong climate resilience plans for coastal cities and communities, taking into account increasing sea levels and the possible dangers caused by melting sea ice.
  • Raising Public Awareness: Educate the public about the effects of melting Antarctic sea ice, cultivating a feeling of community responsibility and motivating individuals to take action to prevent climate change.

@the end

The catastrophic loss of Antarctic sea ice endangers world sea levels, weather patterns, and underwater habitats. To combat climate change, reduce greenhouse gas emissions, and promote sustainable practises, immediate action is essential. We can preserve the Antarctic region and coastal populations throughout the world from the effects of melting sea ice via international collaboration, research, and public awareness. The moment to act is now, for future generations will bear the repercussions of inactivity.

Aviation Safety: The Critical Need for Comprehensive Reforms

A catastrophic accident at Mangalore airport in 2010 killed 158 persons. Despite past warnings and Public Interest Litigation (PILs) brought by the Environment Support Group, the responsible authorities failed to address safety issues regarding the airport’s second runway. It emphasises the system’s lack of accountability and transparency, the failure to learn from previous catastrophes, and the urgent need for reforms in India’s aviation sector.

Background

  • The Environment Support Group highlighted concerns about the Mangalore airport’s second runway’s inadequacy during emergencies in 1997. The NGO’s PIL, however, was dismissed by the Karnataka High Court.
  • Another PIL emphasised the runway’s potential hazards in 2002, but it met the same end. Dissatisfied with the ruling, the organisation petitioned the Supreme Court, which decided that the government must follow applicable laws and environmental standards while building the airport.
  • Following the incident in Mangalore, the Ministry of Civil Aviation established the Civil Aviation Safety Advisory Council (CASAC) to investigate flaws and recommend corrective actions.
  • CASAC criticised the court of inquiry for failing to identify major flaws and proposed solutions, notably at airports like as Mangalore and Calicut. Their warnings, however, were ignored by the Ministry and the DGCA.
  • The second disaster in Calicut on August 7, 2020, which claimed 21 lives, highlighted the disregard for safety issues even further.
  • The suggestions made by the committee formed following the accident have not been adopted due to a preference for business interests before safety.

Lessons ignored

  • Neglecting Compliance with Laws and Norms: Government entities in charge of airport building did not follow applicable laws and environmental norms, as required by the Supreme Court. This carelessness resulted in infractions, which led to the terrible collision.
  • Dismissing Expert Opinions: The Supreme Court’s rejection of the PIL highlighting the violations and safety concerns surrounding Mangalore airport demonstrates a reluctance to hold government authorities accountable. Despite expert views, the judiciary’s refusal to interfere jeopardised the pursuit of justice and the prevention of future catastrophes.
  • Lack of Accountability: Pilots were frequently blamed alone for accidents, while systemic flaws and regulatory failings were ignored. The aviation industry’s lack of accountability maintained a culture of irresponsibility and hampered efforts to address underlying safety issues.
  • Failure in Accident Investigations: The DGCA and AAIB investigations failed to discover the root causes of accidents and provide effective prevention measures. Instead than addressing systemic flaws, investigations frequently blamed pilot error, leaving the true issues unsolved.
  • Neglecting Recommendations: The Ministry of Civil Aviation and the DGCA ignored the Civil Aviation Safety Advisory Council’s (CASAC) concerns and recommendations. Despite professional advise, the refusal to deploy required safety measures such as Runway End Safety Areas (RESA) demonstrates a disrespect for passenger safety.
  • Prioritising Commercial Interests: Commercial interests were prioritised over safety concerns since applying certain safety measures would have had an impact on runway length and payload. This compromise on safety requirements underlines the need of putting passengers’ safety ahead of financial interests.

The Civil Aviation Safety Advisory Council’s (CASAC) role and responsibilities

  • Identify shortcomings: CASAC is entrusted with identifying shortcomings in airports, airlines, and regulatory organisations’ safety measures, legislation, infrastructure, and operating practises. It performs extensive analyses and inspections to identify locations where safety standards may be breached.
  • Provide suggestions: CASAC formulates suggestions and suggests corrective steps based on its findings. These proposals cover a wide range of topics, including operational methods, infrastructure upgrades, training programmes, safety checks, and legislative changes.
  • Examine Reports and Inquiries: CASAC investigates aviation accidents and incidents and analyses accident investigation reports and court of inquiry findings. It evaluates these reports to see if thorough root cause analysis was performed and appropriate preventive measures were proposed. CASAC guarantees that serious errors or safety gaps in reports are discovered and corrected.
  • Advise on Safety Enhancements: CASAC advises the Ministry of Civil Aviation on both urgent and long-term safety enhancements. It offers advice on how to adopt best practises, industry standards, and international safety protocols. The suggestions of CASAC are intended to improve safety results and reduce hazards in the aviation industry.
  • CASAC monitors airports, airlines, and regulatory organisations for compliance with suggested safety measures and rules. It examines progress reports submitted by stakeholders to determine compliance with the planned corrective actions. This monitoring mechanism guarantees that safety enhancements are effectively implemented.
  • Collaboration with Stakeholders: CASAC works with a variety of aviation stakeholders, including airlines, airports, regulatory authorities, industry specialists, and international organisations. It promotes a communal approach to aviation safety through conversations, knowledge-sharing, and cooperative actions.
  • Continuous Evaluation: CASAC evaluates and examines the aviation sector’s safety performance on a regular basis. It evaluates the effectiveness of existing safety measures, detects growing safety concerns, and suggests changes or additional measures as needed.

In the future: The Aviation Sector Requires Immediate Action

  • Regulatory Changes: Launch extensive regulatory reforms to improve monitoring and enforcement. This includes increasing regulatory agencies’ jurisdiction, capabilities, and resources to adequately monitor compliance with safety regulations, such as the DGCA.
  • Independent and Transparent Investigations: Create an independent and transparent accident investigation procedure that discovers fundamental causes without bias or outside influence. This would allow for the deployment of effective preventive measures as well as the promotion of a culture of learning from prior disasters.
  • Safety Management Systems (SMS): Encourage airlines and airports to implement Safety Management Systems (SMS). An SMS is a systematic strategy to detecting and managing safety concerns, as well as ensuring proactive safety measures are in place and encouraging continual improvement.
  • Robust Training and Human Factors Programmes: Improve training programmes for aviation employees, such as pilots, air traffic controllers, and maintenance people, with a focus on emergency procedures, risk management, and human factors. To reduce human error, emphasise the importance of tiredness management and mental well-being.
  • Infrastructure Improvements: Invest in airport infrastructure upgrades and modernization, such as runways, taxiways, and air traffic control systems. Ensure that international safety standards are met and that appropriate improvements are put in place to rectify deficiencies.
  • Improved Collaboration: Encourage collaboration and information exchange among industry players such as airlines, airports, regulators, and international aviation organisations. To push collective efforts towards greater safety, create forums for regular communication and the exchange of best practises.
  • Accountability and transparency should be strengthened to ensure that responsible individuals and entities are held accountable for safety violations. Encourage a culture of transparency in which safety-related information is freely shared and reporting processes protect whistleblowers.
  • Public knowledge and Passenger Education: Through education programmes, raise public knowledge about aviation safety and passenger rights. Allow passengers to make informed safety decisions when selecting airlines, and demand transparency from regulatory organisations.

@the end

The Mangalore airport tragedy and following events have highlighted the crucial need for substantial aviation changes to protect passenger and worker safety. The formation of the CASAC was a positive step forward. To attain a safer aviation environment, however, concerted efforts, commitment, and constant attention are required to prevent accidents, learn from previous mishaps, and assure the safety of passengers and staff in the air.

Calcium-41 radiometric dating      

 A recent study found that Calcium-41 can be utilised in carbon dating in the same way that Carbon-14 can, but with additional advantages.

The Limitations of Carbon Dating

  • Carbon-14 is an unstable and weakly radioactive carbon isotope.
  • It is used to measure the age of carbon-based materials and has a half-life of 5,700 years.
  • Radiocarbon dating provides accurate ages for items derived from live creatures.
  • Carbon-14 cannot be used to establish the age of artefacts older than 50,000 years.
  • Carbon-14 content is measured using three techniques: gas proportional counting, liquid scintillation counting, and accelerator mass spectrometry.

Calcium-41 is being introduced

  • Calcium-41 is an unusual long-lived calcium radioisotope with a half-life of 99,400 years.
  • It is found in the Earth’s crust and is created by cosmic ray interactions in the soil.
  • Calcium-41 is less common than carbon-14.

Atom Trap Trace Analysis (ATTA) was used.

  • ATTA is a technology proposed by scientists at China’s University of Science and Technology.
  • It works by manipulating lasers and detecting neutral atoms.
  • After vaporising the sample, the atoms are laser-cooled and put into a light and magnetic field cage.
  • Calcium-41 atoms can be identified via electron transitions by varying the frequency of the laser.

Importance and Applications

  • With a 12% precision, ATTA can detect one Calcium-41 atom in every 1016 calcium atoms in seawater.
  • It is selective and avoids mixing with atoms of potassium-41.
  • ATTA can be used to investigate various isotopes, including argon-39, krypton-81, and krypton-85.
  • ATTA and Calcium-41 applications include dating ice-covered rocks and investigating Earth-science applications.
