Key takeaways:

 

Understanding Different Categories of Rights

  • Before examining the nature of the 'right to vote' in India, it's important to first understand the various types of rights that exist.
  • Natural rights are those that are inherent to human beings by virtue of their existence. These include rights such as the right to life and personal liberty. While Indian courts may recognize that certain natural rights are reflected within the framework of fundamental rights, they are not independently enforceable.
  • Fundamental rights, listed in Part III of the Indian Constitution, are designed to uphold principles like liberty and equality, as highlighted in the Preamble. The state is restricted from enacting laws that infringe upon these rights. Citizens can directly approach the Supreme Court for enforcement under Article 32.
  • Constitutional rights refer to rights that are embedded within the Constitution but fall outside Part III. These include the right to property, freedom of trade, and protection from unauthorized taxation.
  • Such rights are upheld through laws enacted by the Union or State governments in alignment with constitutional directives. They are enforceable through High Courts under Article 226 or as per the relevant statutory procedures.
  • Statutory or legal rights are those granted by ordinary legislation passed by Parliament or state legislatures. For example, the right to employment under MGNREGA, the rights of tribal communities under the Forest Rights Act, and the right to subsidized food under the National Food Security Act fall into this category. These rights are enforceable through mechanisms provided in the respective laws

 

The Constitution and Universal Adult Franchise

  • Article 326 of the Indian Constitution enshrines the principle of universal adult suffrage. It ensures that all citizens who are 18 years or older and meet other eligibility criteria specified by law have the right to vote. Disqualifications, if any, must be based on constitutional or statutory provisions.
  • To operationalize this, Parliament has passed the Representation of the People Act, 1950, and the Representation of the People Act, 1951. According to Section 16 of the 1950 Act, individuals who are not Indian citizens cannot be listed on the electoral roll.
  • Section 19 further mandates that voters must be at least 18 years old as of the qualifying date and must be ordinarily resident in the constituency.
  • Additionally, Section 62 of the 1951 Act affirms that every individual whose name appears in the electoral roll of a constituency is entitled to vote. However, it also specifies that individuals disqualified under the 1950 Act or those currently incarcerated are not permitted to exercise this right

 Follow Up Question

1.Which of the following statements is/are true of the Fundamental Duties of an Indian citizen? (UPSC 2017)
1. A legislative process has been provided to enforce these duties.
2. They are correlative to legal duties.
Select the correct answer using the code given below:
A. 1 only
B. 2 only
C. Both 1 and 2
D. Neither 1 nor 2

 

Answer (A)
 

1. A legislative process has been provided to enforce these duties. ✅ True

  • Fundamental Duties (Article 51A) are non-justiciable, meaning they are not directly enforceable in a court of law.

  • However, Parliament can make laws to enforce them.

    • Example: The Prevention of Insults to National Honour Act, 1971 enforces the duty to respect the National Flag and the National Anthem.

  • So, a legislative mechanism can be and has been created to ensure compliance.

2. They are correlative to legal duties. ❌ Not necessarily true

  • "Correlative" means that every right has a corresponding duty. While Fundamental Duties reflect expected behavior from citizens, they are not strictly correlative to enforceable legal duties.

  • They serve more as moral obligations and a guide for responsible citizenship.

  • Not all Fundamental Duties have corresponding legal duties, nor are they all backed by punitive laws

Context:
 
On July 22, 1947, the Constituent Assembly of India adopted the National Flag. The adoption of the tricolour marked a pivotal moment in India’s journey towards establishing itself as an independent nation free from colonial rule. In this context, let’s know about the Indian national flag in detail through 10 must-know facts about it.
 
Read about:
 
Evolution of the Indian National Flag
 
Pingali Venkayya
 
 
Key takeaways:
 

Journey of the Indian National Flag:

  • During the early phase of India’s independence movement, a shared symbol was needed to unite the people, prompting Sister Nivedita in 1904 to propose a flag with red and yellow hues symbolizing strength and triumph, and bearing the words "Vande Mataram" in Bengali.
  • The first tricolour design appeared in 1906, featuring blue, yellow, and red stripes and eight stars representing the provinces. Over time, multiple flag versions emerged – the Calcutta flag (1906), the Berlin Committee flag by Bhikaji Cama (1907), and the Home Rule flag (1917) – each capturing the growing nationalist spirit.
  • When India’s independence was announced in 1947 by Lord Mountbatten, a flag committee headed by Dr. Rajendra Prasad was formed to finalize a design inclusive of all communities.
  • With Gandhiji’s consent, Pingali Venkayya’s earlier version (featuring a charkha) was modified by replacing the spinning wheel with the Ashoka Chakra, leading to the current design.
On this date, the Constituent Assembly adopted the Indian National Flag with three horizontal stripes – saffron, white, and green – and the Ashoka Chakra at the center, replacing the earlier charkha. This marked the formal approval of the Tricolour (Tiranga) as the national flag
 

Symbolism of the Tricolour:

Each element of the national flag carries deep meaning:

  • Saffron (Top Stripe): Denotes courage, selflessness, and the spirit of sacrifice, honouring the contributions of freedom fighters.

  • White (Middle Stripe): Represents truth, peace, and purity.

  • Green (Bottom Stripe): Stands for fertility, growth, and auspiciousness, symbolizing India’s agrarian roots and its commitment to sustainability.

  • Blue Ashoka Chakra: The wheel at the center symbolizes movement and progress, based on the idea that life is dynamic and stillness signifies decline

 
  • The 24-spoke blue wheel in the flag is drawn from the Dharma Chakra seen on the Sarnath Lion Capital of Emperor Ashoka, dating back to the 3rd century BCE. It represents the eternal wheel of law, indicating the significance of righteousness, continuous progress, and the passage of time (24 hours a day)
  • While the flag can be produced in various sizes, its proportions are fixed. The length-to-height ratio must always be 3:2, ensuring the flag maintains a rectangular shape
  • Madam Bhikaji Cama was the first Indian to raise the Indian flag on foreign soil during a revolutionary conference in Stuttgart, Germany, on August 22, 1907, symbolizing the country’s desire for independence on the international stage
  • The Flag Code of India, 2002, outlines the rules and etiquette related to the use, display, and hoisting of the National Flag. It consolidates all relevant laws, customs, and guidelines for individuals and institutions—public, private, and government—and came into effect on January 26, 2002
 
Follow Up Question
 

1.Consider the following statements in respect of the National Flag of India according to the Flag Code of India, 2002: (UPSC CSE 2023)

 

Statement-I: One of the standard sizes of the National Flag of India is 600 mm * 400 mm.

Statement-II: The ratio of the length to the height (width) of the Flag shall be 3:2.

Which one of the following is correct in respect of the above statements?

(a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I

(b) Both Statement-I and Statement-II are correct and Statement II is not the correct explanation for Statement-I

(c) Statement-I is correct but Statement-II is incorrect

(d) Statement-I is incorrect but Statement-II is correct

 

Answer (b)
 
Statement-I: "One of the standard sizes of the National Flag of India is 600 mm × 400 mm."
✔️ Correct.
According to the Bureau of Indian Standards (BIS) specification under the Flag Code of India, 2002, 600 mm × 400 mm is one of the standard flag sizes.
Statement-II: "The ratio of the length to the height (width) of the Flag shall be 3:2."
✔️ Correct.
This is the standard and official proportion for the Indian National Flag as per the Flag Code of India, 2002

But is Statement-II the explanation for Statement-I?

No.

  • Statement-I talks about a specific size (600 mm × 400 mm),

  • Statement-II refers to the general proportion rule (3:2).

  • While both are correct, Statement-II does not explain why 600 mm × 400 mm is a standard size — it's just one of several standard sizes that follow the 3:2 ratio.

Context:
 
Prime Minister Narendra Modi will travel to the United Kingdom and the Maldives from July 23 to 26, the government said on Sunday. While India and the UK are likely to formally sign the Free Trade Agreement (FTA) during the visit, Modi will be the guest of honour at the Maldives’ Independence Day celebrations.
 
Read about:
 
Free Trade Agreement (FTA)
 
Why the Free Trade Agreement (FTA) matter to India?
 
 
Key takeaways:
 

• The Ministry of External Affairs (MEA) announced that Prime Minister Narendra Modi will undertake an official visit to the United Kingdom from July 23 to 24, 2025, following an invitation from UK Prime Minister Keir Starmer.

• During his stay, PM Modi is scheduled to hold extensive talks with PM Starmer, covering all aspects of India-UK bilateral ties, and will also deliberate on key regional and global issues. Additionally, he is expected to have an audience with King Charles III. The visit will involve reviewing the status of the Comprehensive Strategic Partnership (CSP) with emphasis on areas such as trade, technology, defence, climate change, health, education, and people-to-people connections.

• Although this marks Modi's fourth trip to the UK, it will be his first since Starmer became Prime Minister, following the Labour Party's landslide victory that ended a 14-year Conservative rule in 2024. Modi and Starmer have previously met during multilateral summits, including the G20 in Rio de Janeiro (November 2024) and the G7 in Kananaskis, Canada (June 2025).

• A major highlight of the visit is expected to be the signing of the India-UK Free Trade Agreement (FTA), which was finalised in May 2025 after nearly three years of negotiations. The agreement is anticipated to eliminate tariffs on 99% of Indian exports and streamline the process for UK exports such as whiskey, automobiles, and other goods to enter the Indian market, enhancing bilateral trade.

• In the second leg of his journey, PM Modi will travel to the Maldives — his first visit since President Mohamed Muizzu assumed office in November 2023. He will attend the 60th Independence Day celebrations of the Maldives on July 26 as the ‘Guest of Honour’, according to the MEA.

• This visit is seen as a significant step in repairing India-Maldives relations, which began on a tense note after President Muizzu requested the withdrawal of Indian military personnel stationed with aviation assets. Those personnel were eventually replaced by technical experts. Muizzu’s October 2024 visit to India set the stage for reconciliation, and Modi’s upcoming visit aims to build on that progress.

• The MEA emphasized that the trip underscores India’s commitment to its maritime neighbour under the ‘Neighbourhood First’ policy and Vision MAHASAGAR, offering a chance to further deepen bilateral cooperation and strengthen the strategic partnership

 

Free Trade Agreement (FTA)

 

  • A Free Trade Agreement (FTA) is a pact between two or more countries aimed at reducing or eliminating barriers to trade between them. These barriers typically include tariffs (taxes on imports), quotas (limits on the amount of goods that can be traded), and various kinds of restrictions or regulations that make international trade more difficult or expensive.
  • The main objective of an FTA is to promote economic cooperation by making it easier for countries to buy and sell goods and services from each other. By lowering or removing tariffs, the cost of importing and exporting goods is reduced, which can benefit both producers and consumers. For instance, consumers in one country might enjoy cheaper imported products, while exporters in another country can access new markets for their goods.
  • An FTA usually covers a wide range of sectors, including goods, services, investments, and sometimes intellectual property rights. In addition to reducing tariffs, these agreements may also set rules to ensure fair competition, protect investments, simplify customs procedures, and encourage transparency in trade-related regulations.
  • FTAs can be bilateral (between two countries) or multilateral (involving more than two). For example, the India-UK Free Trade Agreement aims to ease trade between the two countries by removing duties on a large share of their exports and imports, making it easier for Indian companies to access the UK market and vice versa.
  • While FTAs can bring significant economic benefits, they are also subject to criticism. Some argue that they may harm local industries that are not yet competitive on a global scale, or that they may favour stronger economies in negotiations. As a result, governments often conduct thorough negotiations to ensure that the agreement supports national interests and protects sensitive sectors

Context:
 
Only when soils receive the nutrients do they produce food that nourishes rather than merely fills stomachs. This is no longer just an agricultural issue; it’s a public health imperative.
 
Read about:
 
What is ‘Soil Health Card’ scheme?
 
What is the health of the soil?
 
 
Key takeaways:
 
 
  • According to the Indian Institute of Soil Science (IISC), an adequate level of Soil Organic Carbon (SOC) falls between 0.50% and 0.75%. However, renowned soil scientist and World Food Prize Laureate Dr. Rattan Lal suggests that soils should ideally contain 1.5% to 2% carbon to ensure optimal health.
  • Indian soils are also found lacking in essential elements such as sulphur and key micronutrients like zinc, iron, and boron, with deficiencies ranging from moderate to severe.
  • The current condition of several regions’ soils is so degraded that they could be likened to patients requiring critical care, underscoring the urgency of restoring their fertility to enable sustainable production of nutrient-rich food.
  • In light of these concerns, the Indian Council for Research on International Economic Relations (ICRIER) has partnered with OCP Nutricrops to tackle soil degradation both within India and internationally. OCP Nutricrops specializes in innovative solutions for soil health and fertilization, with a focus on promoting sustainable agriculture. The partnership is aimed at crafting and scaling data-backed, region-specific soil nutrition strategies to boost both crop yield and nutritional quality.
  • In the fiscal year 2024–25, India exported 20.2 million tonnes of rice out of a global total of 61 million tonnes. At the same time, it operates the largest food distribution scheme in the world — the Pradhan Mantri Garib Kalyan Yojana (PMGKY) — which offers 5 kilograms of free rice or wheat per person every month to over 800 million citizens.
  • Despite this, the Food Corporation of India is holding 57 million tonnes of rice as of July 1, 2025 — the largest stockpile in two decades and nearly four times the required buffer stock of 13.54 million tonnes.
  • Poverty has also seen a dramatic decline. The share of the population living in extreme poverty (earning less than $3 a day at 2021 PPP rates) dropped from 27.1% in 2011 to just 5.3% in 2022.
  • Nonetheless, challenges remain. The National Family Health Survey (NFHS-5, 2019–21) revealed that 35.5% of children under five are stunted, 32.1% are underweight, and 19.3% are wasted. India's approach to food security must therefore shift from merely addressing hunger to ensuring proper nutrition.
  • An often-underestimated factor in this context is soil health. Deficiencies in micronutrients not only reduce agricultural productivity but also compromise the nutrient content of the food grown.
  • For instance, when soil is low in zinc, crops like rice and wheat also end up deficient in it. This leads to a nutritional gap in human diets and contributes to problems such as childhood stunting, which negatively impacts a person’s physical development, mental capacity, and long-term productivity.
  • SOC plays a crucial role in determining the physical, chemical, and biological characteristics of soil — including its water retention and nutrient efficiency. The question of what level of SOC is sufficient continues to be debated among experts
 
Follow Up Question
 
1.Consider the following statements: (UPSC 2017) 
The nation-wide ‘Soil Health Card Scheme’ aims at
1. expanding the cultivable area under irrigation.
2. enabling the banks to assess the quantum of loans to be granted to farmers on the basis of soil quality.
3. checking the overuse of fertilizers in farmlands.
Which of the above statements is/are correct?
A. 1 and 2 only   
B.  3 only   
C. 2 and 3 only   
D. 1, 2 and 3
 
Answer (B)
 

The Soil Health Card Scheme, launched by the Government of India in 2015, aims to promote balanced use of fertilizers and improve soil health by providing farmers with a card that contains information about the nutrient status of their soil and recommendations for appropriate dosage of nutrients.

Let’s analyze the statements:

  1. Expanding the cultivable area under irrigation – ❌
    This is not the objective of the Soil Health Card Scheme. It pertains more to schemes like Pradhan Mantri Krishi Sinchayee Yojana (PMKSY).

  2. Enabling banks to assess loans based on soil quality – ❌
    Banks do not use Soil Health Cards to determine loan amounts. This is not a stated goal of the scheme.

  3. Checking the overuse of fertilizers in farmlands – ✅
    Yes, one of the primary objectives is to promote judicious use of fertilizers by educating farmers about the actual nutrient needs of their soil

 
 

How gender remains a primary barrier to women’s workforce participation?

For Prelims Examination: Current events of national and international significance

For Mains Examination: GS III - Economy

Context:

As India celebrates the 79th Independence Day this week, it is also a moment to reflect on the country’s journey towards inclusive growth. Over the years, women’s participation in the workforce has evolved

 

Read about:

Periodic Labour Force Survey (PLFS)

Gross domestic product (GDP)

 

Key takeaways:

 

Women’s Participation in the Workforce

  • Beyond factors such as ageing, disability, or other circumstances that prevent working-age adults from entering the labour market, India’s workforce participation clearly reflects a gender gap.
  • As per the Periodic Labour Force Survey (PLFS) 2022–2023 by the National Sample Survey Office (NSSO) under the Ministry of Statistics and Programme Implementation, around 80% of men are part of the labour force, compared to only about 40% of women.
  • The female labour force participation rate in India continues to trail behind that of many countries with similar income levels and stages of development. This means women remain significantly underrepresented in economic activity.
  • While many women do work, their contributions often go unrecognised in the country’s gross domestic product (GDP). The disparity is not limited to rural areas or women with limited education—urban women, including those with higher education degrees, are also absent from the workforce.

Structural Barriers

  • Although women enjoy equal rights under the law, practical challenges continue to hinder their workforce participation, most of which are structural. Inflexible work hours, unequal pay, limited access to training and skill-building, poor digital literacy, inadequate safety measures, and the responsibility of domestic and childcare duties restrict women’s employment opportunities—particularly in blue- and grey-collar sectors.
  • These jobs often demand long, fixed shifts, leading families to discourage women from pursuing them. The double load of household work and paid employment further disadvantages them.
  • Pay inequality remains another major challenge, prompting some women to leave the labour force entirely. The global gender pay gap reflects this entrenched imbalance: according to the Bureau of Labour Statistics, in 2024, women earned roughly $0.83 for every dollar earned by men, indicating a 17% wage gap.

Impact of the Gig Economy

  • The rapid growth of the gig-platform economy has also reinforced gender imbalances. Jobs such as delivery driving are largely male-dominated and are often perceived as unsafe or socially unsuitable for women, further reinforced by societal stigma.
  • Research by economists like Uma Rani shows that, despite promoting themselves as flexible and empowering, many gig platforms replicate existing gender biases. Women tend to be concentrated in lower-paying roles such as domestic work or beauty services, while men dominate better-paid segments like delivery or transport.

Addressing the Challenges

  • Overcoming these issues demands a multi-dimensional strategy targeting cultural, structural, and economic barriers. Stronger enforcement of minimum wage laws could help narrow pay disparities. Employment policies should also incorporate childcare and maternity-related costs to encourage female participation.
  • Workplace safety must be prioritised by ensuring basic infrastructure such as CCTV surveillance, adequate lighting, clean sanitation facilities, and childcare services. Providing transport and accommodation options could further improve retention rates.
  • From a policy standpoint, greater investment in vocational and skill-based training for women—particularly in rural areas—combined with efficient job-matching systems would enhance opportunities. The establishment of formal grievance redressal mechanisms across sectors is essential to give women the confidence to report workplace issues.
  • Additionally, making recruitment processes more transparent, instead of depending on referrals or word-of-mouth, would encourage more women to apply. Expanding and enforcing labour laws to ensure formal contracts and social security coverage would further strengthen these measures

 

 

Follow Up Question

1.Which of the following statements about the employment situation in India according to the periodic Labour Force Survey 2017-18 is/are correct? (UPSC CAPF 2020)
1. Construction sector gave employment to nearly one-tenth of the urban male workforce in India
2. Nearly one-fourth of urban female workers in India were working in the manufacturing sector
3. One-fourth of rural female workers in India were engaged in the agriculture sector
Select the correct answer using the code given below:
A. 2 only       
B. 1 and 2 only           
C. 1 and 3 only           
D. 1, 2 and 3

 

Answer (C)
 
  • Statement 1 – Correct: According to PLFS 2017–18, the construction sector indeed employed around 10% of the urban male workforce.

  • Statement 2 – Incorrect: Nearly one-fourth of urban female workers were employed in the other services sector, not manufacturing. Manufacturing’s share was lower.

  • Statement 3 – Correct: About one-fourth of rural female workers were engaged in agriculture.

So, only statements 1 and 3 are correct

India has billed its ambitious push for E20 petrol — 20 per cent ethanol blended fuel — and a progressive move towards E27 to be a green leap forward. For car owners, especially those driving older models, the transition is proving to be a leap of faith instead
 
Read about:
 

What is ethanol?

What is ethanol blending?

 

Key takeaways:

 

Ethanol Blending and Global Lessons

  • Ethanol is created by fermenting agricultural residues from crops such as sugarcane and corn. Once produced, it is blended with petroleum to dilute the fuel and lower emissions. The most common blend in use is E10, which contains 10% ethanol.
  • However, some vehicle owners argue that they were neither consulted nor adequately informed about the shift towards higher ethanol blends and their potential effects on vehicles. Brazil’s decades-long ethanol blending programme is often cited as a possible model for India to adopt.
  • In Brazil, higher ethanol blends like E20 and beyond gained public acceptance through the introduction of flex-fuel vehicles, strict government regulations, visible price benefits, and widespread public awareness campaigns.
  • The country began promoting ethanol-based fuels in the 1970s as a strategy to reduce dependency on the volatile oil market. Today, most fuel stations in Brazil offer consumers a choice between blended petrol—typically containing 18–27% ethanol—and E100, which is pure hydrous ethanol.
  • This was accompanied by the rollout of “flex-fuel” cars capable of running on either ethanol or petrol, allowing drivers to select the cheaper option—often ethanol, which costs 25–35% less than blended gasoline.
  • Brazil’s policy was also implemented in phases to ensure that owners of older vehicles were not disadvantaged, as these vehicles might be more susceptible to ethanol-related wear.
  • In contrast, India currently lacks flex-fuel vehicle options, and there are growing concerns that filling E20 in older internal combustion engine vehicles (especially those manufactured before 2023) could lead to faster damage.
  • This is due to ethanol’s higher water content, which increases the risk of corrosion, as well as a noticeable reduction in performance and fuel efficiency. Many Indian car owners view the E20 rollout—introduced without clear labelling or consumer choice at petrol pumps—as an imposed government mandate.
  • Using higher ethanol blends in vehicles not designed for them also brings technical issues. Ethanol burns at a higher temperature than petrol, making non-flex-fuel cars harder to start in cold weather.
  • While E10 generally does not affect performance, blends above this level can cause operational issues in standard engines. The risk of corrosion is particularly high in older engines and in two-wheelers, where engine blocks are often made from lower-grade aluminium or steel

 

 Follow Up Question

1.According to India's National Policy on Biofuels, which of the following can be used as raw materials for the production of biofuels? (UPSC 2020)

1. Cassava
2. Damaged wheat grains
3. Groundnut seeds
4. Horse gram
5. Rotten potatoes
6. Sugar beet
Select the correct answer using the code given below:
A. 1, 2, 5, and 6 only
B. 1, 3, 4, and 6 only
C. 2, 3, 4, and 5 only
D. 1, 2, 3, 4, 5 and 6
 
Answer (A)
 

The National Policy on Biofuels (2018) allows production of biofuels from a wide range of raw materials, including:

  • Non-food feedstocks like cassava and sugar beet.

  • Damaged food grains unfit for human consumption like damaged wheat and rotten potatoes.

However, edible oilseeds such as groundnut and pulses like horse gram are not permitted for ethanol production, since they are part of the regular food chain.

So, in your list:

  •  Cassava – allowed.

  •  Damaged wheat grains – allowed.

  •  Groundnut seeds – not allowed (edible oilseed).

  •  Horse gram – not allowed (food pulse).

  •  Rotten potatoes – allowed.

  •  Sugar beet – allowed
