From UPSC perspective, the following things are important :
Prelims level: Government Initiatives and Programmes;
Mains level: Issues related to affordability of LPG gas;
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)

From UPSC perspective, the following things are important :
Prelims level: Global Rankings; Trends of solar energy production;
Mains level: Factors contributed to India becoming the third-largest producer of solar power in 2023.
Why in the News?
In 2023, India overtook Japan to become the world’s third-highest producer of solar power, according to a report by the International Energy Analytics Agency Ember.
Global Solar Energy Production:
- The leading producer of solar power in the world is China which produced 584 BU of solar power in 2024 – more than the next four countries combined (the United States, Japan, Germany and India).
- India generated 113 billion units (BU) of solar power in 2023 compared to Japan’s 110 BU.
- The installed solar energy capacity has increased by 30 times in the last 9 years and stands at 81.81 GW as of Mar 2024.
- India’s solar energy potential is estimated to be 748 GWp as estimated by National Institute of Solar Energy (NISE).
- Power demand in Japan decreased by 2% (2 BU) in 2023 after rising in 2021 and 2022, thus allowing India to overtake Japan.
Other factors to make India the third-largest Solar power producer in 2023:
- Government Initiatives: India has implemented various policies and initiatives to promote renewable energy, particularly solar power.
- The government launched the Jawaharlal Nehru National Solar Mission (JNNSM) in 2010, aiming to promote the development and use of solar energy in the country.
- Subsequently, various state-level policies and incentives were introduced to encourage solar power generation.
- For example Gujarat Solar Energy Policy (Target is 36 GW of solar energy by 2036).
- Investment and Financing: There has been significant investment in the solar power sector in India, both from domestic and international sources.
- For example PM Surya Ghar, Muft Bijli Yojana, the scheme is projected to entail an investment of ₹75,000 crore.

From UPSC perspective, the following things are important :
Prelims level: NA
Mains level: Issues related to Unemployment vs Wages;
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.

From UPSC perspective, the following things are important :
Prelims level: HDI Index;
Mains level: Key issues related to Human Development;
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)

From UPSC perspective, the following things are important :
Prelims level: Diseases; Widal Test, Salmonella Typhi Bacteria;
Mains level: NA
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.

From UPSC perspective, the following things are important :
Prelims level: LCA, CRISPR Cas9;
Mains level: NA
Why in the news?
Scientists have successfully used CRISPR-Cas9 gene editing to restore vision in individuals with a rare form of inherited or congenital blindness.
- The groundbreaking clinical trial, named “BRILLIANCE,” demonstrated promising results in improving vision and quality of life for participants with Leber congenital amaurosis (LCA), a severe vision disorder.
What is Leber Congenital Amaurosis (LCA)?
- LCA is a rare genetic disorder that primarily affects the retina the ‘light-sensitive’ tissue at the back of the eye. It leads to severe visual impairment or blindness at birth or within the first few months of life.
- It is inherited in an autosomal recessive manner, meaning a child needs to inherit one defective gene from each parent to develop the condition.
- There are several genes associated with LCA, with mutations in at least 14 different genes known to cause the disorder.
- These genes generally affect the development and function of photoreceptors or the retinal pigment.
Key highlights of the BRILLIANCE trial:
- The BRILLIANCE trial involved 12 adults and two children diagnosed with LCA, a condition characterized by early-onset vision loss.
- Participants received a single dose of a CRISPR gene therapy called EDIT-101, designed to correct mutations in the CEP290 gene responsible for LCA.
- In this case, CRISPR-Cas9 cuts out the faulty DNA segment in the CEP290 gene and replaces it with a healthy DNA sequence, restoring the function of the CEP290 protein crucial for vision.
- Out of 14 participants, 11 experienced improved vision without serious side effects.
Back2Basics: CRISPR-Cas9 Gene Editing
- CRISPR-Cas9 stands for Clustered Regularly Interspaced Short Palindromic Repeats and CRISPR-associated protein 9.
- It is a technology that allows geneticists and researchers to edit parts of the genome by altering sections of the DNA sequence.
- Emmanuelle Charpentier and Jennifer Doudna’s work on CRISPR-Cas9 as a ‘molecular scissor’ earned them the 2020 Nobel Prize in chemistry.
- The system consists of two key components:
- Cas9: This is the enzyme that acts like a pair of molecular scissors. It is responsible for cutting the DNA strand at a specific location, allowing for the removal, addition, or alteration of DNA at that site.
- Guide RNA (gRNA): This is a piece of RNA that is designed to find and bind to a specific sequence of DNA that matches its code. The gRNA guides the Cas9 enzyme to the exact spot in the genome where an edit is desired.
- Mechanism:
- The process begins with the design of a gRNA that matches the DNA sequence where an edit is needed.
- Once inside the cell, the Cas9 enzyme and the gRNA form a complex that can identify and bind to the target DNA sequence.
- The Cas9 then cuts the DNA at this location.
- After the DNA is cut, the cell’s natural repair mechanisms can be harnessed to add or remove genetic material, or to make specific changes to the DNA.
