  • India’s retail inflation slips to over 5-year low, opens door to more rate cuts

    Why in the News?

    The decline in food prices is seen as a major reason for the drop in inflation. After two rate cuts by the RBI, inflation is expected to stay below 4% in the coming months, which might lead to another rate cut of 50 basis points.

    What was India’s retail inflation rate in March?

    • March 2025 Retail Inflation Rate: India’s retail inflation eased to 3.34% in March 2025, marking the lowest rate since August 2019.
    • Comparison to Previous Month: This rate represents a decrease from February’s 3.61%, indicating a continued downward trend in inflation.
    • Primary Contributors to the Decline: The significant drop in food prices, particularly vegetables, eggs, and pulses, contributed to the decline. Eg, vegetable prices fell by 7.04% year-on-year in March.

    Why have food prices been a major factor in the decline of retail inflation?

    • Sharp Decline in Vegetable Prices: Vegetable prices saw a significant drop of 7.04% year-on-year in March 2025, compared to a small increase of 1.07% in February. This sharp fall in vegetable prices helped lower overall food inflation.
    • Lower Pulses Prices: Pulses prices fell by 2.73% in March, after a smaller 0.35% decrease in February, contributing to reduced food inflation.
    • Moderation in Overall Food Inflation: Food inflation in March 2025 decreased to 2.69% from 3.75% in February. This marked the lowest food inflation since November 2021, indicating a significant reduction in food price pressures.
    • Improved Farm Output: The moderation in food prices is partly due to better farm output, which led to a more stable supply of food items, especially vegetables and pulses, easing inflationary pressures.
    • Government and Central Bank Support: The government’s expectations for above-average monsoon rains in 2025 are likely to boost farm output further, maintaining lower food prices, which will continue to moderate overall inflation.

    How did the Reserve Bank of India respond to the easing inflation trend?

    • Second Consecutive Rate Cut: On April 9, 2025, the RBI reduced the key policy repo rate by 25 basis points to 6.00%, marking its second consecutive rate cut aimed at stimulating economic growth amid moderating inflation.
    • ​Shift to Accommodative Stance: The RBI changed its monetary policy stance from “neutral” to “accommodative,” signaling a more supportive approach to economic growth while maintaining vigilance over inflation.
    • ​Revised Inflation Forecast: The central bank projected the Consumer Price Index (CPI) inflation to average 4% for the fiscal year 2025–26, down from the previous forecast of 4.2%, reflecting improved inflation dynamics.
    • ​Lowered GDP Growth Estimate: The RBI revised its GDP growth forecast for the fiscal year to 6.5%, down from 6.7%, acknowledging the challenges posed by global uncertainties and trade tensions.

    What risks did the RBI highlight that could impact the inflation outlook?

    • Global Market Uncertainties: The RBI noted that ongoing global uncertainties, such as trade tensions (like the U.S.-China trade war), could disrupt supply chains and impact inflationary pressures in India. Eg, any further escalation in global trade disputes could lead to higher import costs.
    • Adverse Weather Conditions: The RBI pointed out that unpredictable weather events, such as unseasonal rains or droughts, could lead to food supply disruptions and push up food prices, affecting overall inflation. Eg, a poor monsoon could lead to shortages in key agricultural products.
    • Rising Global Commodity Prices: The central bank warned that fluctuations in global commodity prices, including oil and metals, could lead to higher domestic prices, contributing to inflation. Eg, a rise in global crude oil prices could increase transportation and fuel costs in India.
    • Supply Chain Disruptions: The RBI highlighted the risk of supply-side bottlenecks, especially due to external factors like geopolitical conflicts or supply chain disruptions caused by the COVID-19 pandemic. These could raise prices for imported goods and affect domestic inflation. Eg, disruptions in global electronics supply chains could lead to higher prices for tech products.
    • Core Inflation Pressures: The RBI also noted that core inflation, which excludes volatile items like food and fuel, remained persistently high at 4.1%, signaling that inflationary pressures could be more entrenched in the economy, which poses a risk to the inflation outlook. Eg, rising demand for services could contribute to sustained core inflation.

    Way forward: 

    • Strengthen Supply Chain Resilience: The government and RBI should work together to improve supply chain infrastructure and reduce vulnerabilities to global disruptions. This includes addressing logistical bottlenecks, improving domestic production capabilities, and diversifying import sources to mitigate the impact of geopolitical tensions and climate events.
    • Focus on Sustainable Agricultural Practices: To ensure stable food prices, long-term investments in sustainable farming techniques, irrigation systems, and better farm management practices are crucial. This will not only help stabilize food prices but also contribute to higher farm output and lower volatility in food inflation.

    Mains PYQ:

    [UPSC 2024] What are the causes of persistent high food inflation in India? Comment on the effectiveness of the monetary policy of the RBI to control this type of inflation.

  • Beware of child traffickers, Supreme Court cautions parents

    Why in the News?

    Recently, the Supreme Court said that hospitals will lose their licences if newborn babies go missing. It also directed High Courts to make sure all pending child trafficking case trials are finished within six months.

    What did the Supreme Court warn parents about regarding child trafficking?

    • Vigilance Against Child Trafficking: The Supreme Court warned parents to be “extremely vigilant” to protect their children from trafficking for purposes such as sexual exploitation, forced labour, and begging. A slight negligence or carelessness could lead to severe consequences.
    • Consequences of Negligence: The court highlighted that the pain parents experience when losing a child to trafficking is different and more agonising than the loss of a child due to death. The court emphasised that negligence could lead to the lifetime agony of not knowing the whereabouts or fate of the child.
    • Exploitation of Poor and Vulnerable Families: The court pointed out that traffickers often prey on families from poor sections of society, exploiting their helplessness. This issue is compounded by well-organized trafficking networks that use technology to track victims.

    Why does the court believe child trafficking for forced crime is on the rise?

    • Exploitation of Juvenile Justice Laws: Criminal gangs exploit the legal protection offered to minors under the Juvenile Justice (JJ) Act, using trafficked children for illegal activities like theft, drug peddling, and begging, knowing the penalties are lenient. Eg: According to NCRB 2022, over 5,000 children were apprehended for petty crimes, many suspected to be victims of trafficking and coercion by organized gangs who remain untouched by law.
    • Demand-Supply Gap in Adoption System: Long waiting periods and a complex legal framework for adoption in India create a black market for child adoption, encouraging trafficking. Eg: As per Central Adoption Resource Authority (CARA), while more than 29,000 parents were registered for adoption in 2023, only 3,596 adoptions took place—leading to illegal demand and fueling child trafficking networks.
    • Weak State Response and Enforcement: The court criticized state governments like Uttar Pradesh for lack of seriousness in tracking trafficking cases and failing to appeal against bail orders granted to traffickers. Eg: In the case heard, 13 accused granted bail by the Allahabad High Court absconded, and their whereabouts remained unknown for months, showing systemic gaps in enforcement.

    How did the Supreme Court respond to the bail granted by the Allahabad High Court in the child trafficking case?

    • Criticized the High Court’s Decision as Callous: The Supreme Court strongly condemned the Allahabad High Court’s decision to grant bail, calling it “very callous” and insensitive given the gravity of the crime. Eg: The bail allowed 13 accused in an inter-State child trafficking racket to go free, most of whom later absconded, frustrating the investigation.
    • Cancelled the Bail of the Accused: The apex court revoked the bail orders and directed that the accused be taken into custody without delay. Eg: The accused included a nurse at a primary health centre in Chhattisgarh who played a key role in illegal infant sales under the guise of adoption.
    • Ordered Speedy Trial: The court directed that the trial be completed within six months to ensure justice is not delayed. Eg: This was aimed at avoiding procedural delays and ensuring accountability in crimes involving vulnerable children.

    What actions did the Supreme Court direct hospitals to take in cases of missing newborns?

    • Ensure Complete Protection of Newborns: Hospitals must take full responsibility to safeguard infants immediately after birth, ensuring no unauthorized person can access them. Eg: If a newborn goes missing from a maternity ward, the hospital administration will be held accountable for negligence.
    • Strict Monitoring and Accountability Measures: Hospitals were warned that if newborns are found trafficked, they could face suspension of license and legal action. Eg: A nurse involved in an infant trafficking racket from a Primary Health Centre in Chhattisgarh was among the accused in the case.
    • Implement Protocols for Birth and Discharge: The court emphasized the need for strict procedures during childbirth and discharge, including documentation and identity verification. Eg: Hospitals must verify the identity of guardians or parents before handing over the baby, to prevent impersonation or baby-swapping.

    Way forward: 

    • Strengthen Surveillance and Inter-agency Coordination: Establish a centralized digital monitoring system linking hospitals, child welfare committees, and law enforcement to track births, adoptions, and missing children in real time.
    • Community Awareness and Legal Safeguards: Launch nationwide awareness campaigns on child trafficking risks and ensure strict enforcement of child protection laws with fast-track courts for trafficking cases.

    Mains PYQ:

    [UPSC 2023] Development and welfare schemes for the vulnerable, by its nature, are discriminatory in approach.” Do you agree? Give reasons for your answer.

    Linkage: Child victims of trafficking are undoubtedly among the most vulnerable. This PYQ examines the nature of welfare schemes for vulnerable populations, which is relevant to the effectiveness of state interventions aimed at preventing child trafficking and rescuing victims.

  • Delamination of the Indian Plate

    Why in the News?

    Recent studies reveal that the Indian Plate is splitting into two, with the lower part detaching and sinking into the Earth’s mantle, a process called delamination, as published by the American Geophysical Union.

    About Delamination:

    • Delamination in tectonic plates refers to the process where the lower part of a continental plate, including the lower crust and/or lithospheric mantle, splits and sinks into the Asthenosphere.
    • This process is driven by density differences and can lead to rapid uplift, changes in stress regimes, and altered magmatism.
    • It can occur in various tectonic settings, including compressional zones, subduction zones, and intraplate regions. 
    • The denser lower part of the plate, including the lower crust and/or lithospheric mantle, is less buoyant than the less dense asthenosphere, leading to sinking.
    • High temperatures can also weaken the lithosphere and facilitate delamination.

    Delamination of the Indian Plate

    Indian Plate and Its Splitting:

    • The Indian Plate has been colliding with the Eurasian Plate for about 60 million years, causing the formation of the Himalayas and influencing regional seismic activity.
    • It is shifting northward at a rate of approximately 5 cm per year..
    • The lower, denser part of the Indian Plate is detaching and sinking into the Earth’s mantle.
    • This may lead to increased seismic activity due to shifts in tectonic stress.
    • In regions like the Himalayan collision zone, delamination results in fractures that increase stress in the Earth’s crust, raising the likelihood of seismic events.

  • Who was Sir Sankaran Nair (1857-1934)?

    Why in the News?

    PM recently remembered Sir Chettur Sankaran Nair, a nationalist and jurist who famously fought a courtroom battle against British officials involved in the Jallianwala Bagh massacre of 1919.

    Nair’s stand in the courtroom is now a subject of a forthcoming film, Kesari Chapter 2.

    Who was Sir Sankaran Nair (1857-1934)?

    About Sir Sankaran Nair:

    • Born in 1857 in Mankara village, Kerala, Nair came from an aristocratic family.
    • He was educated at Presidency College in Madras and pursued a law degree.

  • Unnecessary amendment: On the RTI Act

    Why in the News?

    The Right to Information (RTI) Act has clearly helped make those in power more accountable in India. However, in recent years, there have been efforts to weaken some of its important provisions, even though the Act — a major reform — was passed 20 years ago.

    What is the role of Section 8(1)(j) of the RTI Act in promoting transparency?

    • Balances Privacy and Public Interest: Section 8(1)(j) permits denial of personal information only if it has no relationship to public activity or interest or causes an unwarranted invasion of privacy. Eg: An officer’s medical records may be withheld, but details of their salary or qualifications can be disclosed if it serves public interest.
    • Includes a Public Interest Override: Even if information is personal, it must be disclosed if larger public interest is involved. Eg: A bureaucrat’s caste certificate was disclosed in public interest when he was accused of using a fake caste certificate to secure a reserved post.
    • Enhances Accountability of Public Officials: Prevents misuse of power by allowing scrutiny of officials’ actions, qualifications, and benefits. Eg: RTI queries have uncovered cases of bogus educational degrees among elected representatives and civil servants.
    • Empowers Citizens to Seek Information: It strengthens democratic participation by giving citizens access to relevant information on public functionaries. Eg: Citizens have used RTI to access asset declarations of elected representatives and government officers.
    • Prevents Blanket Denial of Information: Ensures that authorities cannot reject RTI requests merely by labeling the information as ‘personal’; they must justify how it affects privacy and weigh it against public interest. Eg: Information about government employees’ attendance records or transfers can be accessed to detect nepotism or irregularities.

    Why does Section 44(3) of the DPDP Act, 2023 worry transparency advocates?

    • Removes Public Interest Safeguard: Section 44(3) amends Section 8(1)(j) of the RTI Act by eliminating the provision that allowed disclosure of personal information in public interest. Eg: A fake caste certificate case could now be shielded from scrutiny as the information might be denied without evaluating public interest.
    • Enables Blanket Denial Through Vague Definition: The term “personal information” is broad and undefined, enabling authorities to classify many types of public-relevant data as private. Eg: Details like educational qualifications or property disclosures of public servants could be denied under the label of “personal”.
    • Undermines RTI as a Transparency Tool: It weakens the RTI Act’s core intent by restricting access to information that previously helped expose corruption and misconduct. Eg: RTI requests that once revealed official misconduct or nepotism in postings may now be rejected citing privacy under the DPDP Act.

    How does the DPDP amendment deviate from the intent of the K.S. Puttaswamy judgment?

    • Ignores the Balancing Principle of Privacy and Transparency: The K.S. Puttaswamy judgment (2017) upheld the right to privacy but emphasized that it must be balanced with other fundamental rights, including the right to information and public interest. Eg: The DPDP amendment removes the RTI Act’s public interest test, allowing personal information to be withheld even when it reveals corruption or fraud.
    • Undermines Democratic Accountability: The judgment did not suggest overriding transparency laws like RTI but stressed minimum and necessary restrictions on information access. Eg: Instead of proportionate safeguards, the DPDP Act allows authorities to blanket-deny RTI requests without assessing public relevance.
    • Distorts the Spirit of “Informed Citizenry”: Puttaswamy emphasized that transparency is essential for democracy, and privacy cannot be used to shield public officials from scrutiny. Eg: Information such as public officials’ property details or caste certificates may now be refused, limiting citizens’ ability to hold them accountable.

    What information could now be denied under the amended RTI provisions as ‘personal’?

    • Educational Qualifications and Certificates: Details about the academic background or degrees of public servants could be withheld as “personal information” under the amended provision. Eg: RTI queries that previously revealed fake degrees of elected representatives may now be denied.
    • Caste and Community Certificates: Information related to caste status, often crucial in verifying eligibility for reservation benefits, may be deemed private. Eg: In cases where a public official allegedly used a fake caste certificate, such details could be denied under the privacy shield.
    • Property, Assets, and Financial Disclosures: Disclosures regarding property holdings, assets, and liabilities of government employees might be refused by classifying them as personal. Eg: RTI applications that earlier exposed disproportionate assets could now be blocked.

    Way forward: 

    • Restore Public Interest Safeguard: Amend the DPDP Act to reinstate the public interest clause from Section 8(1)(j) of the RTI Act, ensuring transparency is not overridden by vague privacy claims.
    • Define ‘Personal Information’ Clearly: Provide a narrow and precise definition of “personal information” to prevent misuse and ensure critical public accountability data remains accessible.

    Mains PYQ:

    [UPSC 2020] “Recent amendments to the Right to Information Act will have profound impact on the autonomy and independence of the Information Commission”. Discuss.

    Linkage: The discussion from 2020 highlights the ongoing attention on potential changes to the RTI Act. It shows that the issue of amending the RTI Act and its effects has been a concern for some time.

  • How govern-mentality exacerbates the problem of farmers’ stubble burning

    Why in the News?

    A new study by researchers Sujit Raghunathrao Jagadale and Javed M. Shaikh from IIM Amritsar looks at the issue of stubble burning by examining how government policies and market systems are failing to manage the problem effectively.

    Why do farmers continue stubble burning despite its harm to air quality?

    • Cost-Effective Method: Stubble burning is the cheapest way for farmers to clear their fields after harvesting. Eg: Farmers burn stubble to quickly prepare their land for the next crop, especially for wheat, without incurring high labor or machinery costs.
    • Lack of Affordable Alternatives: There are limited affordable and efficient alternatives to stubble burning. Eg: Farmers often do not have access to technology or subsidies for machines that can manage stubble, such as Happy Seeder or bio-decomposers.
    • Government’s Focus on High-Yield Crops: The Minimum Support Price (MSP) policy incentivizes the cultivation of wheat and rice, leading to monocropping. Eg: Farmers are encouraged to grow rice continuously, which results in an abundance of stubble that needs to be disposed of quickly.
    • Debt and Economic Pressure: Many farmers face financial pressures, including debt and low returns on their crops, which makes burning stubble a way to save time and money. Eg: Farmers often sell their crops to middlemen at low prices, leaving them with insufficient income to invest in sustainable farming practices.
    • Lack of Strong Enforcement or Support: Although stubble burning is penalized, enforcement of laws is weak, and farmers often feel the state does not provide adequate support for eco-friendly methods. Eg: Despite penalties, farmers feel little pressure to change practices when there is insufficient governmental support or infrastructure for alternatives.

    How does India’s MSP policy influence stubble burning?

    • Encourages Monocropping: The MSP policy promotes the cultivation of high-yield crops like rice and wheat, leading to monocropping, which results in a large amount of stubble that must be cleared. Eg: Farmers in Punjab often grow rice followed by wheat, creating a cycle where large quantities of rice stubble need to be burned to prepare the soil for the next crop.
    • Limits Crop Diversification: The MSP system prioritizes wheat and rice over other crops, making it economically unfeasible for farmers to switch to more sustainable practices or crops that would reduce stubble burning. Eg: Despite the potential for growing other crops, farmers focus on rice and wheat to benefit from MSP, leaving them with stubble that they have no economically viable option to manage.
    • Financial Constraints: The MSP rates for crops like rice and wheat have remained stagnant, making it harder for farmers to invest in alternatives to stubble burning, such as machinery or composting. Eg: With wheat MSP seeing only minimal increases, farmers struggle to cover costs for labor and inputs, leading them to resort to stubble burning as the most cost-effective option to clear fields.

    What has the government done in this situation?

    • Implemented Subsidies for Machinery: The government has provided subsidies for the purchase of machinery like the Happy Seeder to help farmers manage stubble without burning. Eg: The Punjab government has distributed equipment like straw management machines under the Sub-Mission on Agricultural Mechanization to reduce stubble burning.
    • Awareness Campaigns: The government has conducted awareness programs to educate farmers about the harmful effects of stubble burning and encourage them to adopt alternative practices. Eg: The Ministry of Agriculture and local bodies in states like Punjab and Haryana have launched campaigns to raise awareness about the environmental and health risks of stubble burning.
    • Legal Measures and Penalties: Various state governments, including Punjab, have imposed fines and penalties on farmers found burning stubble, aiming to deter the practice. Eg: The Punjab government introduced a fine for stubble burning, with penalties reaching up to Rs 2,500 for each violation, although enforcement remains challenging.

    Way forward: 

    • Promote Crop Diversification: Encourage farmers to shift from paddy to less water-intensive and non-stubble-generating crops through assured procurement and better MSP for alternative crops. Eg: Incentivize crops like millets and pulses to reduce stubble generation.
    • Strengthen Support and Infrastructure: Scale up access to sustainable stubble management technologies and ensure timely financial and logistic support to small and marginal farmers. Eg: Expand reach of Happy Seeder and bio-decomposer solutions through local cooperatives and custom hiring centers.

    Mains PYQ:

     [UPSC 2015] Mumbai, Delhi and Kolkata are the three Mega cities of the country but the air pollution is much more serious probelm in Delhi as compared to the other two. Why is this so?

    Linkage: Delhi’s severe air pollution, especially at certain times of the year, is caused by a combination of its location in the Indo-Gangetic Plain, nearby states burning crop stubble, and weather conditions that trap pollutants.

  • Telangana becomes first State to notify Sub- categorization of SCs

    Why in the News?

    The Telangana government has officially implemented the sub-categorization of Scheduled Castes (SCs) into three groups, following a Supreme Court judgment in August 2024 that upheld the constitutionality of sub-classifying SCs and Scheduled Tribes (STs) to grant separate quotas for the most marginalized groups.

    Telangana becomes first State to notify Sub- categorization of SCs

    About Scheduled Castes (SCs) and Their Subcategorization:

    • SCs are a historically marginalized group identified in India’s Constitution to receive preferential treatment in education, employment, and political representation.
    • Constitutional Provisions:
      • Article 341: Empowers the President to specify castes as SCs within states or UTs.
      • Article 342: Allows Parliament to include/exclude castes from the SC list.
    • While grouped for reservations, disparities exist within SCs, with some groups being more disadvantaged than others.
    • Subcategorization involves dividing SCs into smaller groups based on social, economic, and educational backwardness, ensuring the most marginalized receive targeted benefits.
    • Sub-classification of SCs and STs for reservations is subject to judicial review to prevent misuse.

    Supreme Court Verdict on Sub-categorization: State of Punjab v. Davinder Singh (2020) Case

    • In its August 2024 verdict, the Supreme Court allowed states to sub-classify SCs and STs, enabling separate quotas for the most marginalized groups.
    • Key Points:
      • Empirical Data: Subclassification must be based on data of systemic discrimination, not political motives.
      • Creamy Layer: Excludes the more advanced members of SCs/STs, applying the creamy layer principle.
      • Quota Limits: No sub-categorization can exceed the overall constitutional quota ceiling.
      • First-Generation Benefit: Reservations are restricted to the first generation of a family that has not benefitted from previous reservations.

     

    [UPSC 2005] Which one of the following statements is correct regarding population?

    (a) Bihar has the highest percentage of Scheduled Castes in its population.

    (b) The decadal growth of population of India (1991-2001) has been below 20%.

    (c) Mizoram is the Indian State with the least population.

    (d) Pondicherry has the highest sex ratio among the Union Territories.
