{GS1 – Geo – PG – Climatology} Sudden reversal of the pollution cycle

  • Context (IE | DTE): In the winter of 2022-23, Delhi saw cleaner-than-usual air quality, while Mumbai’s air was more polluted than is usual for the coastal city. The PM 2.5 level in Mumbai increased significantly during the stubble-burning period.
  • A new research paper concludes that this sudden flip-flop of the pollution cycle is linked to large-scale wind patterns associated with the triple dip La Nina.
  • This change in wind patterns may have contributed to the intrusion of stubble-burning smoke from Punjab and Haryana into parts of peninsular India and Mumbai in the winter of 2022-23.
  • La Nina is a cyclical phase in the equatorial Pacific Ocean involving cooler-than-normal sea surface temperatures.
  • Triple dip La Nina: The La Nina event that lasted for about three years (began in 2020 and extended into early 2023).

To know more about El Nino Southern Oscillation (ENSO) events – the El Nino and La Nina, visit >EL -NINO LA-NINA.

Geographical Reasons

  • Change in wind direction:
    • Winds blowing towards Delhi during this period are usually northwesterly, and they dump pollutants generated by stubble burning (Punjab and Haryana) in the NCR and the Indo-Gangetic Plain.
    • However, in November 2022, these winds were northerly, escaping most of the region in the NCR, including Delhi.
    • Instead, these winds carried pollutants from stubble burning towards the west-south part of India, including Mumbai.
  • Relatively high windspeed in the north and absence of cold day conditions:
    • Air pollution in Delhi-NCR in the winter is linked to low temperature and low wind speed that keeps pollutants trapped close to the surface.
    • However, Surface level winds from November 2022 to January 2023 were also relatively stronger in the north and slower in the southwest parts of the country compared to 2021-22.
    • This, along with the absence of cold day conditions over northwest India till early January, may have prevented parts of the region from experiencing stagnation conditions that can prevent the dispersion of pollutants.
  • Impact of La Nina:
    • In the La Nina phase, winds over the equatorial Pacific Ocean are easterlies.
    • Easterlies from the Pacific and northeasterlies from the Bay of Bengal appear to accelerate the northwesterly flow from north India and converge over the Indian peninsular region, mainly over northern parts of the west coast of India.
    • Thus, it supports the transport of pollutants from North India towards Peninsular India.

{GS3 – Envi – Air Pollution} Revocation of GRAP Stage II

  • Context (PIB): The Commission for Air Quality Management (CAQM) has decided to revoke Stage II of the Graded Response Action Plan (GRAP) in the entire National Capital Region (NCR).
  • Delhi’s average Air Quality Index (AQI) was recorded at 231, which is about 70 AQI points below the threshold for invoking Stage-II actions (Delhi AQI 301-400) under GRAP.
  • Although Stage-II restrictions are lifted, all actions outlined under Stage-I of GRAP will continue to be enforced.

Graded Response Action Plan (GRAP)

  • GRAP is a set of emergency measures aimed at mitigating air pollution in the Delhi National Capital Region (NCR) that come into effect once the air quality index (AQI) reaches a certain threshold.
  • It was initially proposed by the Central Pollution Control Board (CPCB) in 2016 and was first notified by the Ministry of Environment, Forest, and Climate Change in 2017.
  • Implementing Agency: Since 2021, the GRAP is enforced by the CAQM.
  • The GRAP considers multiple pollutants, including ozone, sulfur dioxide, and oxides of nitrogen, not just PM2.5 and PM10 concentrations.
  • State governments in the NCR may restrict BS-III petrol and BS-IV diesel four-wheelers under Stage 3 (severe category).

    To know more about AQI, refer to CA-24-September-2023

{GS3 – Envi – CC} HP Environment friendly Schemes

  • Context (DTE): The Himachal Pradesh (HP) budget for the year 2024-25 has introduced initiatives aimed at promoting sustainable development and supporting farmers.

Mukhya Mantri Harit Vikas Chhattravriti Yojana (CM Green Development Scholarship Scheme)

  • Postgraduate science and engineering graduates will receive two-year scholarships to conduct research on climate change and environmental conservation in two villages within each assembly.
  • The goal is to address climate threats and foster sustainable practices.
  • This initiative not only supports higher education but also promotes practical solutions for environmental challenges.
  • The collaboration with the Union Ministry of Environment, Forest, and Climate Change and the German development agency GIZ enhances knowledge exchange and expertise.

Rajiv Gandhi Natural Farming Startup Scheme

  • It has been introduced with a focus on chemical-free farming.
  • ten farmers from each panchayat will be encouraged to adopt natural farming practices.
  • Existing farmers engaged in agriculture will receive priority.
  • Those who participate and grow chemical-free grains (eliminating chemicals from wheat and maize) will receive a maximum of 20 quintals of grain per family at the minimum support price (MSP).
  • MSP is a government-set price at which agricultural products are purchased from farmers.
  • It acts as a safety net to ensure that farmers receive a fair and remunerative price for their produce.
  • Additionally, the state will purchase naturally grown wheat at Rs 40 per kilogram and maize at Rs 30 per kilogram, the highest rates in the entire country.

{GS3 – S&T – Tech} Fintech – UPI

  • Context (TH): The Parliamentary Standing Committee on Communications and Information Technology is worried about foreign-owned fintech apps (Walmart-backed PhonePe and Google Pay) dominating India.
  • They suggest promoting local players to address this concern.
  • PhonePe holds the leading market share in volume terms, followed by Google Pay, with 46.91% and 36.39% (Oct and Nov 2023). In the same period, NPCI’s BHIM UPI had a market share of only 0.22%.
  • Fintech companies were also being used for money laundering.
    • For example, an Abu Dhabi-based app named Pyppl, administered by Chinese investment scammers, posed challenges for Indian law enforcement agencies in tracking the money trail from scams conducted on the platform.

Significance of UPI

  • Minimal Impact of Fraud
    • The fraud-to-sales ratio (representing fraudulent transactions compared to the total) has remained at around 0.0015% over the years despite the increased volume of transactions in the last five years.
  • According to McKinsey’s Global Payments Report (September 2023), the advantages of instant payments are,
    • Helps in eliminating the hidden costs associated with managing cash transactions.
    • Has induced a shift in consumer behaviour, enhancing security and digital commerce access.

Committee’s recommendations

  • Need for effective regulation of digital payment apps due to the increasing use of digital platforms for payments in India.
  • Promoting local players because regulatory bodies like the RBI and the NPCI would find it more feasible to control local apps compared to foreign apps operating in multiple jurisdictions.
  • The committee’s recommendations align with NPCI’s 30% volume cap on UPI transactions issued in November 2020.
  • This cap limits the total transactions initiated by third-party apps (like PhonePe and Amazon Pay) to 30% of the overall transactions made using UPI interfaces cumulatively over the three preceding months.
  • The rationale was to promote the growth of UPI and achieve market equilibrium by encouraging both existing and new players to scale up consumer outreach.
  • Apps exceeding this cap were initially given two years to comply with the directive, and the compliance timeline was extended to December 31, 2024.

Way forward

  • A balanced mix (Local fintech players + Foreign fintechs) should be allowed to evolve, varying across areas like payments, lending, wealth management, and insurance.
    • Local fintech players have a natural advantage in understanding the Indian customer, ecosystem, and market infrastructure.
    • Foreign fintechs excel in new technologies and global connectivity.

{GS3 – S&T – Tech} Satyendra Nath Bose & Quantum Physics

  • Context (TH): This year marks 100 years of Satyendra Nath Bose’s discovery.
  • He was an Indian physicist specialising in mathematical physics.
  • He is best known for his work on quantum mechanics in the early 1920s, providing the foundation for Bose-Einstein statistics and the theory of the Bose-Einstein condensate.

Early life

  • Bose was born in Calcutta (now Kolkata) in 1894.
  • After completing his schooling, he joined Presidency College to study physics.
  • After a few years, he was appointed as a faculty in the newly founded Rajabazar Science College.
  • Later, he joined the Dhaka University as a lecturer.

Significant contribution

  • Bose & Saha (his friend) published the first English translation of Einstein’s papers on general relativity.
    • Saha was one of the first people to start finding applications of the developing quantum theory to molecular physics.
  • Developed the foundation for Bose-Einstein statistics:
    • Bose read Planck’s papers on the distribution of energy in blackbody radiation to teach this material to his class.
    • It was while teaching quantum theory in Dacca that he first noticed a logical problem in all known derivations of the Planck law of blackbody radiation.
    • In 1924, Saha stayed with Bose in Dhaka and pointed out the 1923 papers of Wolfgang Pauli, Einstein and Paul Ehrenfest and their relation to Einstein’s 1917 paper.
    • This led him to develop Bose statistics – a new method to count states of indistinguishable particles and applied it to his derivation of Planck’s radiation law.
    • He discovered the correct set of equations to use to work out the behaviour of collections of photons (particles of light).
  • Bose Discoveries (along with Einstein)
    • Define the two classes of subatomic particles: fermions and bosons.
    • Discovered Bose-Einstein Condensate (BEC)
Numerous Nobel Prizes were awarded for research related to the concepts of the boson and the Bose-Einstein Condensate. Bose was never awarded a Nobel Prize.
  • Planck’s law: It states that electromagnetic radiation from heated bodies is not emitted as a continuous flow but is made up of discrete units or quanta of energy.
    • Planck’s law is about radiation. All hot objects, from a bowl of hot soup to the Sun, emit radiation in a range of frequencies.
  • Black bodies: objects that can emit light but cannot reflect it.

Albert Einstein’s principle of general relativity

  • Formulated in 1915, it revolutionised our understanding of gravity.
  • Instead of viewing gravity as a force between masses, Einstein proposed that massive objects cause a curvature in the fabric of spacetime.
  • In other words, massive objects, like planets or stars, bend the space and time around them, creating what we perceive as gravity.
  • Einstein’s idea helped explain why Mercury moves a bit strangely in its orbit and why light from stars bends when it passes close to the Sun.

Bose-Einstein Statistics & Bose-Einstein Condensate (BEC)

  • Bose–Einstein statistics, proposed by Satyendra Nath Bose and expanded by Albert Einstein.
  • It applies to particles known as bosons (e.g., certain types of atoms).
  • Unlike classical statistics, it treats these particles as indistinguishable, emphasising their quantum nature.
  • Classical statistics (like those of Maxwell-Boltzmann) treat particles (electrons, protons, and neutrons) as distinguishable – each has its own identity and energy state.
  • It introduces the idea that identical particles can occupy the same quantum state. This concept is crucial for understanding the behaviour of particles, especially at extremely low temperatures.

Bose-Einstein Condensate (BEC)

  • Imagine you have a collection of bosonic particles, like atoms, cooled down to near absolute zero. At such low temperatures, the principles of Bose–Einstein statistics come into play.
  • As you cool these particles, they start behaving less like individual entities and more like a single, collective quantum entity. They gather in the same lowest energy state, essentially becoming indistinguishable and behaving collectively.
  • The result is Bose–Einstein condensate – a unique state of matter where a large number of particles occupy the same quantum state, behaving as one superfluid entity.
  • Bose–Einstein statistics tell us how particles that follow quantum rules (like bosons) behave.
  • Bose–Einstein condensate is what happens when a bunch of these particles are cooled to super-low temperatures.

Bosons vs Fermions

  • Bosons and fermions are fundamental particles that exhibit distinct characteristics in quantum physics.
  • Bosons have integer spins (0, 1, 2, …), and fermions possess half-integer spins (1/2, -1/2, …).
  • Bose-Einstein statistics governs bosons. Multiple bosons can occupy the same quantum state simultaneously. i.e. they disobey the Pauli exclusion principle.
  • In contrast, fermions, Subject to the exclusion principle, no two identical fermions can occupy the same quantum state simultaneously.
  • Bosons include Photon, Gluon, W and Z bosons, and Higgs bosons.
  • Fermions include Electrons, protons, and neutrons.

Quantum Mechanics

  • It is a branch of physics that explores the tiny building blocks of this world, particles like electrons and photons.

Development

  • In 1898, J J Thompson discovered electrons using the properties of cathode rays.
  • In 1900, Max Planck sowed the seeds for quantum theory by stating that electromagnetic energy could only be emitted in quantized form. His quanta are now called photons by physicists.
    • Energy Packets (Quanta): This means that energy comes in specific, well-defined amounts rather than as a continuous flow. Albert Einstein later embraced this idea.
  • In 1905, Einstein proved the photoelectric effect by suggesting that light is made up of packets of energy. With that, he proved that light exists in discrete packets of energy, giving the light a particle behaviour.

Central concepts

Wave-particle duality
  • It suggests that particles, such as electrons and photons, can exhibit both wave-like and particle-like behaviours, depending on the circumstances.
    • Double-slit experiment by Thomas Young in 1801. This experiment proved the wave nature of light, and this result was opposite to what Einstein proved with the photoelectric effect (particle nature).
Quantum Superposition
  • It means particles can exist in multiple states at the same time.
Entanglement
  • If two particles become entangled, changing the state of one particle instantaneously affects the other, no matter how far apart they are.
Uncertainty Principle
  • Proposed by Werner Heisenberg. It says that you can’t know everything about a particle at the same time. If you precisely know a particle’s position, you’ll have less certainty about its speed, and vice versa.

{Prelims – Envi – Species} Northern Green Anaconda

  • Context (DTE): Research has unveiled the existence of two genetically distinct species within the Anaconda family.
  • The two distinct species are- the southern green anaconda (Eunectes murinus) and the newly identified northern green anaconda (Eunectes Nakajima).
  • Despite their similar appearances, these species exhibit a staggering 5.5% genetic difference, indicative of their evolutionary divergence nearly 10 million years ago.
  • It is the largest, heaviest, and second-longest snake (after the reticulated python) in the world.
  • Characteristics:
    • Size and Adaptations: Their nostrils and eyes positioned atop their heads enable breathing and vision while submerged.
    • Physical Description: Olive-colored with large black spots blend seamlessly into lush Amazonian habitats.
    • Habitat and Prey: Green anacondas predominantly inhabit South America’s Amazon and Orinoco basins, preying on a diverse range of animals, including capybaras, caimans, and deer.
    • Predatory Behavior: Utilizes their large, flexible jaws, anacondas immobilise and consume prey without venom, relying on suffocation and swallowing techniques.
  • Conservation Status: IUCN: Least Concern | CITES: Appendix II
