Current Affairs for UPSC Civil Services Exam – May 10, 2024

{GS1 – IS – Population} EAC-PM Paper on Religious Diversity in India

• Context (IE I TOI): A report by the Economic Advisory Council to the PM has said that minorities are thriving in India and not just protected.

• The analysis relied on the Religious Characteristics of States Dataset 2017 to track religious composition across countries.
• The Paper was titled ‘Share of Religious Minorities: A Cross-Country Analysis’.
• The paper analyses changes in minority population shares across countries from 1950 to 2015.
• The study focused only on countries where the majority religion accounted for more than 50 per cent of the total population in 1950.

Findings of the Report

• The share of the Hindu population in India has dipped by 7.82 per cent, while that of Muslims, Christians, Sikhs and Buddhists has seen a rise. The Jain and Parsi communities witnessed a dip.
• Of the 35 OECD countries studied, 25 were from Europe, and the share of majority religious denominations has decreased by 29 per cent in these countries.

• India’s demographic changes, with a dipping majority population and rising minority population, are in line with global trends, as seen in Europe.
  • However, these changes stand out when compared to India’s neighbours, highlighting the unique nature of India’s demographic shift.
• The rise in the share of minorities suggested the net result of policy actions, political decisions and societal processes provided a conducive environment for increasing diversity in society.

Some Trivial Facts The share of the Muslim population rose from 9.84 per cent to 14.09 per cent. The share of the Christian population rose from 2.24 per cent to 2.36 per cent. The share of the Sikh population increased from 1.24 per cent to 1.85 per cent. The share of the Buddhist population rose from 0.05 per cent to 0.81 per cent. The share of Jains declined from 0.45 per cent to 0.36 per cent. The share of the Parsi population declined 85 per cent from 0.03 per cent to 0.0004 per cent.

PM’s Economic Advisory Council (PMEAC)

• The Economic Advisory Council to the Prime Minister (PMEAC] is a non-constitutional, non-permanent and independent body constituted to give economic advice to the GoI, specifically the PM.
• It was established to offer diverse perspectives on key economic issues to help raise awareness within the government.
• The Council is often restructured with different organizational formats, led by internationally recognized economists.
• Established in September 2017 for two years, it replaced the former PMEAC, chaired by former RBI governor C Rangarajan during Prime Minister Manmohan Singh’s tenure.

Organisation

• A Chairperson chairs the PMEAC, which consists of eminent economists as members.
• It now has a Chairperson, a Member Secretary and two part-time members.
• It is supported in its functions by a team of officials and administrators.
• There is no fixed definition of the exact number of members and staff of the PMEAC.
• For administrative, logistic, planning and budgeting purposes, the NITI Aayog replaced the erstwhile Planning Commission to serve as the Nodal Agency for the PMEAC.

{GS2 – IR – UN} UN Counter-terrorism Trust Fund

• Context (TOI): India has donated $500,000 to the UN counter-terrorism trust fund.

• With this recent contribution, India’s total financial support to the trust fund is now $2.55 million.
• India’s contribution supports the United Nations Office of Counterterrorism (UNOCT) ‘s global programs on countering the financing of terrorism (CFT) and countering terrorist travel (CTTP).
• These programs aim to enhance the capacities of member states in eastern and southern Africa.

UN Counter-terrorism Trust Fund The Fund was established in 2009 by the Secretary-General and transferred to UNOCT. The Fund accepts contributions from Governments, inter-governmental and non-governmental organisations, private institutions and individuals.

{GS3 – Agri – Crops} Biocontrol Agent against Foot Rot disease

• Context (IE): Punjab Agricultural University has come up with biocontrol agent Trichoderma asperellum to combat ‘foot rot’ disease, prevalent in Basmati rice varieties.

• Foot rot or Bakane disease, is a fungal disease that affects Basmati rice crops, particularly at the seedling stage, though it might also cause infection after transplantation in case infected seedlings are transplanted.
• It is caused by the fungus Fusarium verticillioides, a soil-seed-borne pathogen that spreads the infection through the plant’s root and eventually colonises the stem base.
• Impacts: Infected seedlings first turn pale yellow, then elongate and dry up, and eventually (usually) die.
• Treatment: Currently, seedlings are treated with Trichoderma harzianum before sowing and transplantation. Seeds are also treated with fungicides such as Sprint 75 WS before sowing. However, these are harmful to the soil, and can be toxic for consumers of the rice.

{GS3 – Envi – Air Pollution} Nitrogen Dioxide (NO2) *

• Context (DTE): A study by Stanford University highlighted health risks associated with gas and propane stoves. These appliances can significantly elevate indoor air pollution levels of nitrogen dioxide (NO2), a known respiratory pollutant.
• The research discovered that homes using gas or propane stoves expose residents to an average annual increase of 4 parts per billion (ppb) of NO2.
• This is concerning because the increase is equal to 75% of the WHO recommended safe limit for indoor and outdoor NO2 exposure.
• The study affirmed that cooking food emits minimal to no NO2, and electric stoves produce none.

Mitigation Strategies

• Effective range hoods that vent outdoors.
• Ensuring proper ventilation while cooking.
• Consideration of alternative cooking appliances, such as electric stoves or induction cooktops.

About Nitrogen Dioxide (NO2) It is one of six widespread air pollutants. It is formed when fossil fuels such as coal, oil, and methane gas are burned at high temperatures. NO2 and other nitrogen oxides in the outdoor air contribute to particle pollution and to the chemical reactions that make ozone. Road traffic is the principal outdoor source of nitrogen dioxide. Nitrogen dioxide causes a range of harmful effects on the lungs, including: Increased inflammation of the airways. Worsened cough and wheezing. Reduced lung function. Increased asthma attacks. Nitrous oxide (N2O) is a greenhouse gas with significant anthropogenic sources.

{GS3 – Envi – CC Impacts} Urban Heat Islands

• Context (IE): Around 80% of the people in India have experienced heat waves in the first 15 days of summer and are disproportionately affected by urban heat stress.

• Urban heat island is a temporary phenomenon in which certain pockets within a city experience higher heat load than its surroundings.
• This is due to rising ‘concretisation’ in urban spaces where heat trapped is unable to dissipate easily.
• Urban heat islands result from complex interactions between built environments, natural factors, and human activities.

Factors Contributing to Urban Heat Islands (UHI)

Credit: Semantic Scholar

• Urban deserts: Cities can be thought of as virtual deserts with almost no vegetation and materials that are almost completely impermeable to rain (for e.g. Asphalt). This combination leads to a lack of evapotranspiration, which increases sensible heat.
• Urban canyons: The tall canyons formed by city buildings trap radiant energy in their walls, blocking wind flow that would have otherwise provided ventilation. This “canyon effect” blocks heat emissions from being released into the atmosphere, contributing to increased temperatures.
• Humidity effects: Although there is little difference in the amount of water that cities and countryside retain in their atmospheres, the higher urban temperatures effectively lower the relative humidity (since warm air can hold more water than cold air).
• Urban haze: A haze of air pollution that hangs over many cities can act as a miniature greenhouse layer, preventing outgoing thermal radiation from escaping from urban areas.
• Anthropogenic heat: Heat from the burning of fossil fuels contributes towards increased urban temperatures.

Impacts of Urban Heat Islands

• Economic implications: Increased healthcare costs, decreased worker productivity, rise in volatility of prices of food grains, reduced tourism potential.
• Strain on energy resources due to increased demand for air conditioning and refrigeration, leading to higher greenhouse gas emissions and strain on electrical grids.
  • Studies have shown that UHIs can increase electricity consumption for cooling in urban areas by up to 20% compared to non-urban areas.
• Adverse health effects: Heat-related illnesses, such as heat exhaustion and heatstroke, become more prevalent during heatwaves.
• Altered microclimates and ecosystem disruption by altering wind patterns, rainfall distribution, and atmospheric stability, thus affecting urban hydrology and vegetation, leading to reduced evapotranspiration rates, increased stormwater runoff, and decreased water quality in urban streams and rivers.
• Reduced Air Quality through the phenomenon of thermal inversion, which traps pollutants close to the ground. The combination of high temperatures, stagnant air, and increased emissions from vehicles and industrial activities leads to the formation of ground-level ozone, worsening air quality.

Way Forward

• Urban greening and heat-resistant infrastructure: Increasing the number of parks, green roofs, and vertical gardens, using cool roofs and pavements, etc.
• Building Regulations: Implementing building codes and regulations that promote energy-efficient construction, use of heat-reflective materials, and proper insulation can significantly reduce UHI effects.

{GS3 – IE – Banking} Look Out Circulars & Loan Defaulters *

• Context (IE): The Bombay High Court ruled that public sector banks (PSBs) cannot request Look Out Circulars (LOCs) against loan defaulters.
• The ruling quashed the centre’s Office Memoranda (OM) that empowered PSBs to issue LOCs.
• Existing restraint orders issued by competent authorities, courts, Debt Recovery Tribunals, or investigative/enforcement agencies remain unaffected by the court’s order.

Background

• LOCs were issued based on OMs from the Ministry, starting from October 27, 2010.
• In September 2018, a provision was introduced to issue LOCs if an individual’s departure posed a threat to the “economic interest” of the country.
• Later, a new clause empowered the chairperson of the State Bank of India (SBI) and CEOs of other Public Sector Banks (PSBs) to request immigration authorities to issue LOCs against default borrowers.

Reasons for quashing the Office Memoranda (OM)

• The court described these LOCs as “strong-arm tactics” to bypass legal processes. Such tactics violate fundamental rights guaranteed under Articles 14 and 21 of the IC.
• The fundamental right to travel abroad cannot be restricted by executive action without a legal basis.
• Allowing banks to act as judges and executioners violates Article 21 of the IC.
• The government failed to prove that debt had been recovered through the denial of travel permission.
• The court deemed the inclusion of only PSBs (not Private banks) in the LOC issuance to violate Article 14 of the IC and be arbitrary. It disagreed with the distinction between borrowers from PSBs and those from private banks.

About Look Out Circulars (LOCs)

• The Bureau of Immigration of the Ministry of Home Affairs (MHA) issues lookout circulars (LOCs).
• These LOCs allowed authorities at any departure port to prevent PSB debtors from leaving India.

Default borrowers include not only the borrowers but also the guarantors for repayment of loans and the principal officers or directors of corporate entities in debt.

Options for Banks After Court Ruling

• Banks are free to seek orders from courts or tribunals to restrain individuals from travelling abroad.
• Banks can also utilise powers under the Fugitive Economic Offenders Act, 2018, where applicable.

{GS3 – S&T – Defence} Fujian: China’s Aircraft Carrier

• Context (TH): China’s third aircraft carrier, Fujian, completed its maiden sea trials successfully.

{Prelims – Envi – Species} Sperm Whales (Physeter macrocephalus)

• Context (HT): Scientists studying sperm whales have discovered that they communicate through a sort of “phonetic alphabet.”

Credit: NOAA Fisheries

• Sperm whales, or cachalots, are the largest-toothed whales. They are named after the waxy substance spermaceti, an oil sac found in their heads that helps them focus on sound.
• Physical description: They are mostly dark grey, with some having white patches on their belly. Some sperm whales turn white as they age.
• Distribution: They are found in all deep oceans, from the equator to the edge of the pack ice in the Arctic and Antarctic.
• Sperm whales are noteworthy for their acoustic activity, which they use to navigate and communicate.
• It has the largest brain of any animal on Earth, more than five times heavier than the human brain.
• Conservation Status: IUCN: Vulnerable | WPA, 1972: Schedule II
• Threats: Entanglement in fishing gear, vessel strikes, pollution and climate change.

{Prelims – In News} AlphaFold – The AI Model

• Context (IE): Google Deepmind has unveiled the third major version of its “AlphaFold” artificial intelligence model.

• It can predict the structure and interactions of all life’s molecules, including proteins and DNA. It marks the first time that a single system has been able to predict the interactions between nearly all molecular types with state-of-the-art performance.
• AlphaFold 3 expands beyond proteins to provide accurate predictions for protein interactions with other biomolecules in living cells – such as DNA, RNA, and small molecules.
• Earlier versions of AlphaFold focused on predicting the 3D structures of 200m proteins, the building blocks of life, from their chemical constituents.

{Prelims – In News} World Migration Report 2024

• Context (DTE): The World Migration Report 2024 was recently released by the United Nations’ International Organisation for Migration (IOM).
• According to the report, by 2050, over 216 million people across six continents are projected to move within their countries due to climate change.
• Migration serves as a coping or adaptation strategy to mitigate the adverse effects of climate change.
• Factors like political power, governance, and globalised food production also contribute to migration.
