  • Redouble efforts to reduce disaster risks

    What’s the news?

    • In 2023, the rise in disasters is not an anomaly; it’s a disturbing trend. Headlines have been dominated by a relentless wave of bad news: severe flooding in China, devastating wildfires in Europe and Hawaii, and July marking the hottest month ever recorded.

    Central idea

    • The world is standing at a precarious crossroads, where the challenges we face are multiplying faster than our ability to mitigate them. The aftershocks of the COVID-19 pandemic, combined with a complex web of crises encompassing war, debt, and food insecurity, have placed our collective resilience to the test. All of this unfolds against the ever-looming backdrop of the climate crisis, which drives increasingly frequent and severe extreme weather events.

    Disproportionate Impact on Vulnerable Communities

    • Debt crisis: A majority of the 50 countries most vulnerable to climate change also grapple with severe debt issues. India, already one of the world’s most disaster-prone countries, is acutely experiencing this new reality.
    • Extreme weather events: In 2022, disasters or extreme weather events battered the country nearly every day, with this year’s severe monsoon causing widespread loss of livelihoods and lives.

    Solutions Within Reach

    • SDG: The Sustainable Development Goals (SDGs) continue to serve as our most comprehensive blueprint for achieving peace and prosperity.
    • Paris Agreement: Additionally, commitments made in the Paris Agreement to limit global warming to 1.5°C offer a clear path forward.
    • Sendai Framework: The Sendai Framework for Disaster Risk Reduction provides a global framework to reduce disaster risks, although progress in its implementation has been slow.
    • Accelerating Resilience Building: One valuable lesson we have learned from the COVID-19 pandemic is the importance of systemic disaster risk reduction, resilience, and adaptation. The crisis has not only exposed our vulnerability to risks but has also catalyzed innovative approaches, such as digital technologies and modeling. India’s proactive efforts in disaster risk reduction, including state-level disaster management plans and early warning systems, have demonstrated tangible results in reducing mortality from extreme weather events.
    • Financial Reforms for Disaster Preparedness: India’s 15th Finance Commission has introduced significant reforms for disaster risk financing, allocating substantial resources for preparedness, response, recovery, and capacity development. On the international stage, India is championing disaster resilience and sustainability through initiatives like the Coalition for Disaster Resilient Infrastructure and the deployment of its National Disaster Response Force.

    The Transformations We Need

    • Early detection system: Disaster risk reduction must be integrated at all levels of our societies. This includes how we build, invest, and live. One highly cost-effective method is the establishment of early warning systems for all, with India’s support for this endeavor being noteworthy. Such systems can significantly reduce the damage caused by impending disasters. However, it is crucial to recognize that over a third of the world’s population, primarily in the least developed countries and Small Island Developing States, lacks access to these life-saving systems.
    • The Path to a Global Multi-Risk Warning System: Our ultimate goal should be a global multi-risk warning system that covers all types of hazards, be they biological, tectonic, or technological. Improving global data capabilities is essential for better prediction and response to the risks we face. India’s leadership in knowledge sharing, joint data infrastructure, and risk analysis through its G-20 presidency deserves commendation.
    • Leaving No One Behind: We must strengthen international cooperation in disaster prevention, response, and recovery, particularly for countries in the Global South. No one should be left behind in our collective efforts to mitigate the impacts of disasters.

    Conclusion

    • The recent G-20 summit and the outcomes of the Disaster Risk Reduction Working Group offer a unique opportunity to shape a future where we are equipped to withstand disaster risk. As UN Secretary-General António Guterres wisely noted, Extreme weather events will happen. But they do not need to become deadly disasters. Together, through decisive action and unwavering commitment, we can forge a more resilient and sustainable world for generations to come.

  • RBI to discontinue Incremental Cash Reserve Ratio (I-CRR)

    Central Idea

    • The Reserve Bank of India (RBI) announced the phased discontinuation of the Incremental Cash Reserve Ratio (I-CRR) on September 8, 2023.
    • This measure aimed to absorb surplus liquidity created by factors such as the return of Rs 2,000 notes to the banking system.

    RBI’s Decision

    • RBI conducted a review and decided to discontinue I-CRR in stages.
    • The central bank aims to release the impounded amounts gradually to avoid sudden shocks to the system’s liquidity, ensuring orderly money market functioning.

    Understanding Cash Reserve Ratio (CRR)

    • CRR is a fundamental concept before delving into Incremental Cash Reserve Ratio (ICRR).
    • Banks are mandated to maintain a certain portion of their deposits and specific liabilities in liquid cash with the RBI.
    • CRR serves as a crucial tool in the RBI’s arsenal for managing liquidity in the economy and acts as a safety net during times of banking stress.
    • Currently, banks are required to uphold 4.5% of their Net Demand and Time Liabilities as CRR with the RBI.

    Introduction to ICRR

    • I-CRR was introduced on August 10, 2023, as a temporary measure by RBI to absorb surplus liquidity.
    • Banks were required to maintain an I-CRR of 10% on the increase in their Net Demand and Time Liabilities (NDTL) between May 19, 2023, and July 28, 2023.
    • It came into effect from the fortnight starting August 12, 2023.
    • The RBI has the authority to implement an additional measure called Incremental Cash Reserve Ratio (ICRR), in addition to the standard CRR.
    • ICRR is employed during periods characterized by excess liquidity in the financial system.
    • Essentially, ICRR mandates that banks park even more liquid cash with the RBI than what is required under CRR.
    • This serves as a means to further manage and control liquidity in the banking system.

    Reason for I-CRR

    • Excessive liquidity emerged due to factors like the return of Rs 2,000 banknotes, RBI’s surplus transfer to the government, increased government spending, and capital inflows.
    • The daily liquidity absorption by RBI in July reached Rs 1.8 lakh crore.
    • Managing surplus liquidity was necessary to maintain price and financial stability.

    Impact on Liquidity Conditions

    • I-CRR was expected to absorb over Rs 1 lakh crore of excess liquidity from the banking system.
    • It temporarily shifted the banking system’s liquidity from surplus to deficit on August 21.
    • Factors like GST outflows and central bank selling of dollars contributed to tight liquidity.
    • However, liquidity conditions reverted to surplus from August 24.
    • On September 8, RBI absorbed Rs 76,047 crore of surplus liquidity from the system.

    • “Interface interference” manipulates the user interface for deceptive purposes.
    • “Bait and switch” advertises a specific outcome based on user actions.
    • “Drip pricing” conceals elements of prices until later in the transaction.
    • “Disguised advertisement” and “nagging” are also defined in the guidelines.

    Scope of Application

    • The Ministry states that these guidelines will apply to all individuals and online platforms, including sellers and advertisers.

    Challenges in Enforcement

    • Legal experts appreciate the introduction of the draft guidelines but raises concerns about enforcement.
    • They highlight the challenge of conclusively proving whether certain practices qualify as dark patterns.
    • Famous is the example of the “false category” and the difficulty regulators may face in determining if claims like “only 2 rooms remaining – book now!” are genuinely accurate or misleading due to a lack of context.
    • Some categories of dark patterns, such as e-retail sites adding items to users’ carts without their consent, are seen as easier to regulate, while others like “disguised advertisements” may require further clarification.

  • Lab-Grown Human Embryos: A Breakthrough in Science

    embryo

    Central Idea

    • Scientists have successfully developed a “human embryo” in a laboratory without using traditional egg or sperm cells.
    • The model was constructed using a combination of stem cells, which possess the ability to differentiate into various cell types, resulting in a structure resembling an early human embryo.

    Creating Human Embryo artificially

    • This model is considered one of the most comprehensive representations of a 14-day-old human embryo.
    • Multiple research teams worldwide have been working on similar embryo-like models, with approximately six such models published in the current year.
    • While none fully replicate early embryo development processes, they collectively contribute to scientific understanding.

    Challenges in Creating the Model

    • Researchers in Israel utilized stem cells and chemical components, but only a small fraction spontaneously assembled into different cell types.
    • Approximately 1% of the mixture exhibited this spontaneous assembly, making the process inefficient.

    Importance of Embryo Models and Research

    • Ethical constraints prevent direct research on early embryo development after implantation in the uterus.
    • Understanding early stages of embryo development is crucial as most miscarriages and birth defects occur during this period.
    • Such research aids in the comprehension of genetic and hereditary diseases.
    • Insights into why some embryos develop normally and implant successfully can enhance in vitro fertilization success rates.

    Potential of Embryo-Like Models

    • These models enable the study of genetic, epigenetic, and environmental influences on embryo development.
    • They facilitate the investigation of genetic defects and the development of potential genetic therapies.

    Limits of Lab-Grown Embryos

    • Lab-grown embryos are solely for studying the early stages of foetal development.
    • Implantation attempts are prohibited, and these models are typically destroyed after 14 days.
    • Originating from a UK committee proposal in 1979, the 14-day limit aligns with natural embryo implantation completion.
    • Beyond this point, embryos begin exhibiting characteristics of individuality and cannot split into twins.
    • The ethical considerations shift as embryos progress from a clump of cells to entities with individual potential, often marked by the Primitive Streak.

    Insights from Embryo Models

    • Models like the one developed in Israel shed light on DNA duplication errors and chromosome imbalances.
    • These errors are now understood to occur earlier in the development process, during ongoing DNA duplication.
    • Such models aid in identifying the roles of various genes in fetal development, enabling gene manipulation for research purposes.

    Conclusion

    • Lab-grown human embryo models represent a significant scientific achievement.
    • They provide a unique window into early embryo development and the understanding of genetic and developmental processes.

  • What is heat index and why is it important to measure?

    What’s the news?

    • In August, the coastal regions of Iran bore witness to an astonishing and potentially life-threatening event: a scorching heat index of 70 degrees Celsius (°C). Public holidays were declared on August 2 and 3 due to what was described as unprecedented heat.

    Central idea

    • The alarming incidents of rising heat temperatures are not isolated; Iran had already grappled with extreme heat earlier in the year when the Persian Gulf Airport recorded a heat index of 66.7°C. The dire consequences of such soaring temperatures demand our attention and action.

    What is the heat index?

    • The heat index, also known as the apparent temperature or feels-like temperature, is a measure of how hot it feels to the human body when relative humidity is factored in along with the actual air temperature.
    • In essence, it quantifies the discomfort or perceived warmth caused by the combination of high temperatures and high humidity.

    How is the heat index calculated?

    • Dr. Robert Steadman’s Formula: Dr. Robert Steadman, a professor at Colorado State University, developed a complex formula in 1979 to calculate the heat index. This formula considers various parameters, including air temperature and relative humidity.
    • Parameters in the Formula: The formula takes into account the following parameters:
      • Air temperature (in degrees Fahrenheit).
      • Relative humidity (expressed as a decimal, e.g., 50% RH becomes 0.50).
      • Coefficients specific to the formula (c1, c2, c3, c4, c5, c6, c7, c8, and c9).
    • Nonlinear Relationship: The formula is complex because it accounts for the nonlinear relationship between temperature, humidity, and how humans perceive heat.
    • Global Variations: Different countries may have their own variations of heat index calculations, but Dr. Steadman’s formula is widely recognized and used as a standard reference.

    Significance of measuring the heat index

    • Accurate Perception of Heat: The heat index provides a more accurate representation of how hot it feels to the human body compared to the actual air temperature. It factors in relative humidity, which significantly affects human comfort in hot conditions.
    • Health Impact Assessment: Measuring the heat index is crucial for assessing the potential health risks associated with hot weather. It helps identify conditions that may lead to heat-related illnesses, including heat exhaustion and heatstroke.
    • Preventing Heat Stress: High humidity levels, considered in the heat index, can lead to heat stress. Monitoring the heat index assists in recognizing situations where heat stress is more likely to occur, prompting individuals to take the necessary precautions.
    • Issuing Public Warnings: Weather agencies and authorities use the heat index to issue heat advisories and warnings to the public. These warnings inform people about the heightened risks associated with high heat index values, encouraging them to take protective measures.
    • Workplace Safety: Measuring the heat index is vital for ensuring workplace safety, particularly in industries involving outdoor work or non-air-conditioned environments. It enables employers and workers to implement safety measures to prevent heat-related illnesses and injuries.
    • Emergency Preparedness: Emergency response and preparedness agencies rely on heat index information to anticipate and respond to heat-related emergencies. This includes managing heat-related illnesses and addressing the increased demand for cooling during heatwaves.
    • Adapting to Climate Change: With the increasing frequency and intensity of heatwaves associated with climate change, monitoring the heat index becomes essential. It assists in adapting to changing climate conditions and developing strategies to mitigate heat-related risks.

    How does high humidity impact the human body?

    • Heat Stress: High humidity can lead to heat stress, where the body struggles to dissipate excess heat. The typical human core temperature range is 36.1 to 37.2°C. When the body can’t effectively shed surplus heat, the core temperature rises, potentially causing symptoms such as heat exhaustion, rashes, and an elevated heart rate.
    • Reduced Cooling: In high humidity, the body’s natural cooling mechanism, which relies on sweating and evaporation, becomes less effective. The saturated air makes it challenging for sweat to evaporate, hindering the body’s ability to lose excess heat. This results in discomfort and a heightened risk of heat-related illnesses.
    • Perceived Temperature: High humidity can make the air feel significantly hotter than the actual air temperature. This increase in perceived temperature, often reflected in the heat index, contributes to a sense of extreme heat and discomfort.
    • Dehydration Risk: To compensate for reduced evaporative cooling in high humidity, individuals may sweat profusely. This increased sweating can raise the risk of dehydration if fluid losses are not replenished adequately.
    • Respiratory Discomfort: Humid air can pose challenges for individuals with respiratory conditions like asthma. The added moisture in the air may make breathing more difficult, worsening respiratory symptoms.
    • Sleep Disturbances: High humidity can disrupt sleep patterns, as sleeping in a warm and muggy environment can be uncomfortable. Restlessness and difficulties falling or staying asleep may occur in such conditions.
    • Impact on Physical Activities: High humidity can hinder physical performance and work productivity. People may find it more challenging to engage in physical activities or perform tasks in hot and humid conditions.

    Facts for Prelims: Heat-related Terminologies in News

    • Heat stroke: Heat stroke is a serious medical condition that occurs when the body’s temperature regulation system fails, and the body temperature rises to dangerous levels, usually above 104°F (40°C). It can lead to organ damage and even death if not treated promptly.
    • Heat cramps: Heat cramps are painful muscle contractions that can occur during physical activity in hot weather.
    • Heat wave: A heat wave is a prolonged period of excessively hot weather, which can be accompanied by high humidity levels. The World Meteorological Organization (WMO) defines a heat wave as when the daily maximum temperature of more than five consecutive days exceeds the average maximum temperature by 5°C, and the normal minimum temperature is also exceeded.
    • Heat index: It is the measure of how hot it feels when relative humidity is added to actual air temperature. The higher the heat index, the hotter it feels.
    • Thermal stress: It is the stress on the human body caused by high temperatures, humidity, and solar radiation.
    • Urban Heat Island: It refers to the phenomenon where urban areas experience higher temperatures than surrounding rural areas due to human activities like transportation, industrialization, and construction.
    • Wet bulb globe temperature: It is a measure of heat stress in direct sunlight, which takes into account temperature, humidity, wind speed, sun angle and cloud cover.
    • Diurnal temperature range: It is the difference between the maximum and minimum temperatures in a 24-hour period. A low diurnal temperature range indicates high humidity and poor air quality.

    Way forward: Measures to adapt

    • Recognize the Danger: Acknowledge that a heat index value of 67°C or higher can be extremely dangerous for both humans and animals, especially with direct and prolonged exposure.
    • Invest in Early Warning Systems: Develop and invest in early warning systems that provide timely alerts and advisories about extreme heat events. This helps individuals and communities prepare for and respond to heatwaves effectively.
    • Adjust Work Timings: Consider making changes to work schedules to avoid outdoor activities during the hottest parts of the day. This can reduce heat exposure and the risk of heat-related illnesses.
    • Find Sustainable Cooling Solutions: Identify and implement sustainable cooling solutions, such as the use of energy-efficient and environmentally friendly cooling technologies. Ensuring access to air conditioning and promoting better building designs for heat resilience are also important.
    • Promote Public Awareness and Education: Raise public awareness about the risks associated with extreme heat, and educate individuals and communities about heat safety measures. Knowledge empowers people to take proactive steps to protect themselves during heatwaves.

    Conclusion

    • As we confront rising heat index values across the globe, our ability to adapt and mitigate the effects of extreme heat on human health and well-being becomes paramount. Proactive measures, informed by a comprehensive understanding of the heat index, are essential to safeguarding lives and ensuring a sustainable future in the face of escalating climate challenges.
