IOCR Prelims Only | International Relations | Mains Paper 2: Important International Institutions

Why in the news?

Karnataka’s political landscape is rocked by accusations of sexual abuse against a sitting MP belonging to a prominent political family.
Following explicit video leaks allegedly implicating him, Interpol has issued a Blue Corner notice, as he remains on the run.

INTERPOL’s Notice System:

The Interpol issues various types of notices to its member countries about individuals who are either missing or wanted.
While these notices aren’t legally binding and countries aren’t required to act on them, they are commonly used to arrest and extradite suspects.

The following entities can request for a notice:

Notice request by the Member Country
International Criminal Tribunals and the International Criminal Court can also request notices for individuals accused of serious crimes like genocide, war crimes, and crimes against humanity under their jurisdiction.
The United Nations can request notices related to enforcing sanctions imposed by the Security Council.

What are Blue Corner Notice?

Purpose: Blue corner notice, also known as an “enquiry notice,” facilitates sharing critical crime-related information, including criminal records verification and locating individuals.
Example: In January 2020, Interpol issued a blue corner notice to locate fugitive Nithyananda, a self-styled godman.

FLiRT Variants: Latest Twist in the COVID-19 Saga

Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

Why in the news?

The emergence of new variants KP.2 and KP1.1, known as the FLiRT variants, has raised global concerns.

Despite vaccination efforts, these variants pose challenges, leading to concerns about a potential rise in COVID-19 cases.

What are the FLiRT Variants of COVID-19?

KP.2 and KP1.1, dubbed ‘FLiRT’ variants, are descendants of the Omicron JN.1 which spread globally over the winter last year.

Features and Differences from Other Variants

New Spike Mutations: The FLiRT group includes two specific mutations that are believed to enhance the virus’s ability to infect human cells.
Transmission and Evasion: Preliminary studies suggest that KP.2, the more prevalent of the two, may possess enhanced capabilities to evade immune responses generated by vaccines and previous infections.

Are FLiRT Variants Riskier than JN.1?

Increased Immune Evasion: Research indicates that KP.2 shows a significant ability to escape immunity from both the latest vaccines and previous infections.
Reproduction Number: The reproduction number of KP.2 may be higher than that of JN.1, indicating a potentially greater ability to spread.
No definitive evidence: While there’s no definitive evidence that FLiRT variants cause more severe illness, their ability to circumvent immune defences can lead to more infections and, by extension, potential increases in hospitalizations.

PYQ:

[2022] In the context of vaccines manufactured to prevent COVID-19 pandemic, consider the following statements:

The Serum Institute of India produced COVID-19 vaccine named Covishield using mRNA platform.
Sputnik V vaccine is manufactured using vector based platform.

Artificial Rain through Cloud Seeding

Prelims Only | Science Tech | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

Why in the news?

The Uttarakhand government faced scrutiny from the Supreme Court following Forest fires that claimed lives in the state.

Justices highlighted the inefficacy of relying solely on cloud-seeding or rain gods to address the crisis.

Case Study: Experimenting Artificial Rain in India

A recent study published in the Bulletin of the American Meteorological Society (BAMS) highlighted the success of a cloud seeding trial in Maharashtra’s Solapur region, which resulted in an 18% increase in rainfall compared to normal patterns.
Scientists from the Indian Institute of Tropical Meteorology in Pune and other institutes conducted this study.
The experiment targeted warm convective clouds with a height above zero degrees Celsius, releasing calcium chloride particles to stimulate rainfall.
Spanning from 2017 to 2019, the experiment analyzed 276 clouds using advanced tools like automatic rain gauges, radars, radiometers, and aircraft.
Glaciogenic seeding, attempted in clouds containing both ice and water, did not significantly impact rainfall at the seeding location, according to the study’s findings.

About Cloud-Seeding

Cloud seeding is a weather modification technique aimed at altering precipitation patterns by dispersing substances into clouds to stimulate rainfall or snowfall.
It is used to mitigate hail, disperse fog, and either induce precipitation or prevent it from occurring in subsequent days.
It involves the dispersal of substances like silver iodide, potassium iodide, dry ice, and hygroscopic materials such as table salt into the atmosphere.
Techniques include:

Static seeding: promotes ice particle formation in supercooled clouds, and
Dynamic seeding: enhances convective cloud development through the release of latent heat.

Dispersion methods range from aircraft and ground-based generators to newer approaches like drones delivering electric charges or infrared laser pulses.

Limitations: Impact on Environment and Health

Concerns persist regarding the potential accumulation of seeding agents in sensitive ecosystems, although detailed studies have shown negligible impacts.
The chemicals used, such as silver iodide, may potentially damage the environment and cause health issues like iodine poisoning in high concentrations

PYQ:

[2019] In the context of which of the following do some scientists suggest the use of cirrus cloud thinning technique and the injection of sulphate aerosol into stratosphere?

(a) Creating the artificial rains in some regions

(b) Reducing the frequency and intensity of tropical cyclones

(d) Reducing the global warming

The Socio-ecological effects of LPG price hikes

Explained | Economics | Mains Paper 3: Infrastructure: Energy, Ports, Roads, Airports, Railways Etc.
Why in the News?

The ACCESS survey (2014-2015), conducted by the Council on Energy, Environment and Water, found LPG’s cost to be the foremost barrier to its adoption and continued use in rural poor households.

Government Initiatives for LPG Fuel:
- Government Initiatives: The Indian government has promoted using LPG (liquefied petroleum gas) as a clean cooking fuel, particularly in rural households.
  - These initiatives include the Rajiv Gandhi Gramin LPG Vitrak scheme, the ‘PAHAL’ scheme for direct benefit transfers, and the Pradhan Mantri Ujjwala Yojana (PMUY) aimed at providing LPG connections to below-poverty-line households.
- Subsidies and Incentives: The government has provided subsidies and incentives to encourage the adoption of LPG without subsidies for the people who can afford it.
  - For example, the ‘Give it Up’ program encouraged consumers to voluntarily surrender their LPG subsidies, which were transferred to below-poverty-line households.
Challenges:
- Affordability: Despite government efforts, the affordability of LPG remains a challenge for many households, especially those in rural and below-poverty-line communities. Reports indicate that LPG prices in India were among the highest globally around ₹300/litre.
- Dependency on Traditional Fuels: Studies, such as the one conducted in the Jalpaiguri district of West Bengal, highlight the continued dependency of local communities on traditional fuelwood for cooking.
- Forest Dependency: The persistent use of fuelwood has implications for forest conservation and livelihoods, particularly in regions with degraded forests like Jalpaiguri.
Way Forward:
- Need for Comprehensive Solutions: While government initiatives have aimed to promote LPG use, addressing affordability issues and ensuring access to clean cooking fuels for marginalized communities require comprehensive solutions.
- Targeted Subsidies: Implement targeted subsidies for LPG cylinders to make them more affordable for rural and below-poverty-line communities. These subsidies can be based on income levels or geographic locations to ensure that those most in need receive assistance.
Mains PYQ:

Q In what way could replacement of price subsidy with direct benefit Transfer (DBT) change the scenario of subsidies in India? Discuss.(UPSC IAS/2015)

Labour, Jobs and Employment – Harmonization of labour laws, gender gap, unemployment, etc.

Unemployment Vs Wages

Explained | Economics | Mains Paper 3: Inclusive Growth & Issues,Indian Economy
Why in the news?

Recently, there have been contentious talks regarding Pakistan’s unemployment being lower than India’s.

According to Keynes, lower wage rate will lead to lower income of workers and thus to lower demand of goods. Lower demand will lower output that in turn will lower employment.

Issues related to Unemployment vs Wages
- Questioning on Data Accuracy and Interpretation: There is skepticism about the accuracy of unemployment data, particularly regarding the CMIE Consumer Pyramids Household survey. This raises questions about the basis of claims regarding unemployment rates and the subsequent policy responses.
- Labor Force Participation: Concerns are raised about the significant withdrawal of individuals from India’s labor force, indicating potential issues with labor force participation rather than solely unemployment rates.
- Youth Unemployment: The high youth unemployment rate of 45% is highlighted as a significant concern, suggesting challenges in integrating young people into the workforce and addressing their employment needs.
- Informal Employment: The prevalence of informal employment, such as subsistence agriculture and informal wage employment, is noted as a structural issue in the labor market, potentially impacting wages and job quality.
- Wage Levels: Despite low reported unemployment rates, there are concerns about the adequacy of wages, particularly for the poor. This raises questions about the quality of employment and the extent of underemployment or disguised unemployment.
- Policy misalignment: Certain policy proposals, such as increasing public sector employment or implementing fiscal job guarantees, are critiqued for potentially misdiagnosing the problem and offering unsustainable solutions that may not address underlying wage issues.
Steps taken by the Government:
- Pradhan Mantri Rojgar Protsahan Yojana (PMRPY): This scheme incentivizes employers to generate employment by having the government pay the entire 12% employer’s contribution to the Employees’ Provident Fund and Employees’ Pension Scheme for new employees for the first three years of their employment
- Pradhan Mantri Mudra Yojana (PMMY): This scheme provides collateral-free loans up to ₹10 lakh to micro and small businesses and individuals to help them set up or expand their enterprises, thereby promoting self-employment.
- Aatmanirbhar Bharat Package: This economic stimulus package, announced in response to the COVID-19 pandemic, includes various long-term schemes and policies aimed at making India self-reliant and creating employment opportunities.
- Garib Kalyan Rojgar Abhiyaan: This 125-day campaign was launched to boost employment and livelihood opportunities for migrant workers and others affected in 116 districts across 6 states.
- PM GatiShakti: This is a multi-modal connectivity plan that aims to create infrastructure and generate employment opportunities in sectors like roads, railways, airports, ports, and logistics.
Way forward:
- Addressing Labor Force Participation: Implement policies aimed at increasing labor force participation, particularly among youth and marginalized groups, by creating more formal employment opportunities.
- Improving Informal Employment Conditions: Develop strategies to formalize the informal sector by providing incentives for informal employers to register their businesses, improve working conditions, and ensure compliance with labor laws.
- Enhancing Wage Levels: Take steps to improve wage levels, particularly for low-skilled workers engaged in subsistence agriculture, marginal self-employment, and informal wage employment.
Mains PYQ:

Q Besides the welfare schemes, India needs deft management of inflation and unemployment to serve the poor and the underprivileged sections of the society. Discuss.

Human Development Report by UNDP

Giving primacy to Human Development

Explained | Governance | Mains Paper 2: Health & Education

Why in the News?

Two recent reports reveal some important facets of India’s Development.

The Human Development Report 2023-24, published by the UNDP, takes a comparative perspective and maps the achievements in the area of human development.
A paper published by the World Inequality Lab in March 2024 provides long-term trends in income and wealth inequality in India between 1922 and 2023.

About HDI:

The Human Development Index (HDI) is a measurement system used by the United Nations to evaluate the level of individual human development in each country. It was introduced by the U.N. in 1990.

How is the HDI measured?

The HDI is the geometric mean of the three dimensions above, with indices calculated separately for each country using data on life expectancy, schooling and per capita income. The final result always gives a value between 0 and 1 which defines, according to the UNDP, the four degrees of human development detailed below:

Very high: countries with a HDI above 0.80.
High: countries with a HDI between 0.70 and 0.80.
Medium: countries with a HDI between 0.55 and 0.70. (India is here)
Low: countries with a HDI below 0.55.

India’s poor ranking in HDI:

Regional Trends: India’s HDI ranking has improved marginally over the years, but it still lags behind several countries, including Bhutan, Bangladesh, Sri Lanka, and China. In 2022, India ranked 134 out of 193 countries.
Low HDI Value: Despite the incremental improvement in ranking, India’s HDI value remains relatively low. The HDI value increased from 0.633 in 2021 to 0.644 in 2022.
Gender Inequality Index (GII): While India showed improvement in its GII ranking in 2022, moving from 122 out of 191 countries in 2021 to 108 out of 193 countries in 2022, significant gender disparities persist. Notably, India faces one of the largest gender gaps in labor force participation rates, with a substantial difference between men (76.1%) and women (28.3%).
Medium Human Development Categories: India’s HDI ranking places it within the medium human development category alongside countries like Myanmar, Ghana, Kenya, Congo, and Angola.

Key concerns related to Human Development:

Increasing Disparity Between Countries: The report underscores a concerning trend of growing inequality between countries, particularly between those at the upper and lower ends of the Human Development Index (HDI).
Economic Concentration: The concentration of economic power in a few countries is exacerbating global inequality. Nearly 40% of the global trade in goods is controlled by just three or fewer countries
Tech Company Dominance: The dominance of large technology companies further exacerbates inequality, with the market capitalization of the top three companies surpassing the GDP of the majority of countries.

Widening inequality:

Income Disparities in India: The study from the World Inequality Lab reveals stark income disparities in India, with the bottom 50% of the population receiving only 15% of the national income.
- Conversely, the top 1% earns on average 23 times more than the average Indian, and the top 10,000 individuals earn 2,069 times the average Indian.
Reduction of Middle-Class size: During the period from 2014 to 2022, the incomes of the middle 40% of the income distribution have grown slower than the bottom 50%. This trend suggests a potential reduction in the size of the ‘middle class.
High Household Debt and Low Savings: Household debt levels in India have reached a record high of 40% of GDP, while net financial savings have plunged to 5.2% of GDP.

Way Forward:

Promote Inclusive Growth Policies: Implement policies that prioritize inclusive growth, focusing on reducing income disparities, and enhancing access to education, healthcare, and economic opportunities for all segments of society.
Enhance Social Safety Nets: Strengthen social safety nets to provide support to vulnerable populations, including targeted welfare programs, universal healthcare coverage, and unemployment benefits.

Mains PYQ:

Q Despite the consistent experience of high growth, India still goes with the lowest indicators of human development. Examine the issues that make balanced and inclusive development elusive.(UPSC IAS/2019)

Maharashtra’s plan to increase tigers count in Sahyadri-Konkan Wildlife Corridor by translocating tigers from Tadoba-Andhari Tiger Reserve (TATR) (Chandrapur, Maharashtra) underscores the critical role of wildlife corridors in conservation efforts.

About Tadoba-Andhari Tiger Reserve (TATR)

Tadoba became one of India’s earliest national parks when it was declared in 1955, alongside Kanha National Park.
The name “Tadoba” is derived from the deity “Tadoba” or “Taru,” worshipped by local Gond Tribals, and “Andhari” refers to the Andhari River flowing through the reserve.
It was later expanded and officially merged with the Andhari Wildlife Sanctuary in 1993 to form the TATR.
TATR is regarded as one of the world’s most preferred destinations for tiger sightings and is a critical part of Project Tiger, aimed at conserving tigers in India.
The reserve has 115 tigers, including 88 within the forest and 27 in the areas immediately surrounding the reserve.

About Sahyadri-Konkan Wildlife Corridor

The Sahyadri-Konkan corridor (Sahyadri-Radhanagari-Goa-Karnataka), plays a vital role in conserving wildlife, particularly tigers, in the northern Western Ghats region.
It spans throughout the states of Maharashtra, Goa, and Karnataka, specifically through the Western Ghats, one of the world’s eight biodiversity hotspots.

Widal Test: Flaws of Typhoid Diagnosis

Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

Why in the news?

Patients with fever in India often undergo testing and treatment for typhoid fever, primarily relying on the Widal test.

The Widal test, though widely used, has several limitations that affect its accuracy and reliability.

Typhoid diagnosis using Widal Test

The Widal test is used primarily to diagnose typhoid fever.
Typhoid fever, caused by Salmonella Typhi and related bacteria, presents with symptoms like high fever, stomach pain, weakness, and gastrointestinal issues.
It detects antibodies in the patient’s blood against the O (somatic) and H (flagellar) antigens of Salmonella Typhi.
Procedure:

The presence of these antibodies is detected through an agglutination reaction.
The test involves serial dilution of the patient’s serum.
The highest dilution at which agglutination occurs indicates the antibody titer, with higher titers suggesting an active infection.

Diagnostic Challenges:

The gold standard for diagnosing typhoid involves isolating the bacteria from blood or bone marrow cultures, which is time-consuming and resource-intensive.
Widal test is commonly used due to its convenience and accessibility. However, the Widal test’s interpretation is complicated by factors like the need for multiple serum samples, variations in cutoff values, and potential cross-reactivity with antibodies from other infections or vaccines.

Challenges with Widal Test:

Impractical: A single positive Widal test does not confirm typhoid.
Complicated result interpretation: High background antibody levels and variability in test cutoff values.
Cross-reactivity with antibodies from other infections and false negatives due to prior antibiotic therapy undermine test reliability.

Consequences of Widal Test Use:

Erroneous results obscure the true burden of typhoid in India, leading to inappropriate treatment and financial strain on patients.
Overuse of antibiotics based on Widal test results contributes to antimicrobial resistance, exacerbating the challenge of treating typhoid.

PYQ:

[2016] Which of the following statements is/are correct?

Viruses can infect

1. Bacteria

2. Fungi

3. Plants

Select the correct answer using the code given below.
