2. Mahalanobis Distance (1936)

• A multivariate statistical measure used to identify outliers and data anomalies.
• It quantifies the distance of a data point from a distribution, factoring in correlations between variables.
• Widely applied in fields such as public health, market research, and machine learning.

3. Flood Control and Environmental Planning

• In the 1920s, Mahalanobis used historical data to guide flood mitigation in Bengal and Odisha.
• His studies disproved incorrect assumptions (e.g., rising river beds) and recommended drainage improvements and dam construction.
• His early estimates contributed to the Hirakud Hydroelectric Project, inaugurated in 1957.

4. Institution Building: Founder of ISI & Sankhya Journal

• Founded the Indian Statistical Institute (ISI) in Kolkata in 1931, a premier research institute for statistics and mathematics.
• Launched ‘Sankhya’, India’s first statistical journal, fostering academic and applied research.

5. Role in National Planning & Technology Advocacy

• Chief architect of the Second Five-Year Plan, which introduced the Mahalanobis Model — emphasizing heavy industries and public sector-led growth.
• Advocated for digital computing in India. However, during the Cold War, the U.S. denied India access to the UNIVAC computer, fearing Mahalanobis’s pro-Soviet leanings.

India has emerged as a significant player in the global coffee trade, with its exports witnessing a sharp rise of 125% in the past 11 years, increasing from $800 million in 2014–15 to $1.8 billion in 2023–24, and continuing the momentum with over 25% growth in FY2025–26. This export surge highlights India's expanding footprint in the global premium coffee market, driven by a blend of policy support, sustainable cultivation practices, and global demand for specialty coffee.

Key Drivers of Export Growth

The Coffee Board of India, under the Ministry of Commerce, has played a pivotal role in this transformation through:

• Digitalisation of export permits, RCMC, and certificates of origin.
• Export incentives like freight and transit assistance—?3/kg for value-added exports and ?2/kg for green coffee to distant markets (e.g., US, Canada, Japan, Nordic countries).
• Subsidy support of 40% (up to ?15 lakh) for processing units (roasting, grinding, packaging).
• Global market intelligence and regular industry engagement to remove bottlenecks.
• Promotion via GI tags and digital branding campaigns.

These efforts have enhanced India’s readiness to meet stringent import regulations (e.g., EU deforestation norms) while enabling access to new and emerging markets.

Production and Cultivation

India is the 7th largest producer of coffee globally, accounting for about 3.5% of world production and ranks 5th in global coffee exports with a 5% share. The country produces 3.5–4 lakh tonnes of coffee annually, with Karnataka (70%), Kerala, and Tamil Nadu being major contributors.

• Arabica varieties: Kents, S.795, Cauvery, Selection 9.
• Robusta: High-yielding selections suited to Indian climate.

Climatic Features:

• Grown under two-tier shade canopies with over 50 native tree species.
• Arabica thrives at 1000–1500m, Robusta at 500–1000m altitudes.
• Requires 1600–2500 mm rainfall and 15°C–25°C temperature.

India is unique as the only country that cultivates 100% shade-grown coffee, which promotes biodiversity, soil and water conservation, and ensures a sustainable income for 2 million people, including small and marginal farmers.

Specialty and GI-Tagged Coffee

India’s coffee is known for its mild acidity, full-bodied flavour, and fine aroma. Intercropping with spices like pepper, cardamom, and vanilla further enhances its appeal. The country also boasts five regional and two specialty coffees with Geographical Indication (GI) tags, strengthening brand value in global markets.

The historic legacy of Indian coffee dates back over 400 years to the planting of coffee beans by Baba Budan in Karnataka, making it one of the oldest coffee traditions in Asia.

In a major escalation of the ongoing US–Iran tensions, the United States deployed the B-2 Spirit stealth bomber to strike Iran’s fortified nuclear infrastructure, including the heavily guarded Fordow enrichment facility, which was described by President Donald Trump as the “crown jewel” of Iran’s nuclear programme. The strikes signal a new phase in the geopolitical standoff, showcasing advanced US airpower and precision capabilities.

What is the B-2 Spirit Bomber?

The B-2 Spirit, developed by Northrop Grumman during the Cold War, is one of the most advanced strategic bombers in the world. Originally built for penetrating heavily defended Soviet airspace, it remains a key asset in the US Air Force due to its stealth capabilities, long range, and precision payload delivery.

Only 21 B-2 bombers were built, each costing an estimated $2.1 billion, making it one of the most expensive aircraft ever developed. Its bat-wing design and radar-absorbent coating significantly reduce its radar cross-section, making it almost invisible to radar and ideal for deep penetration missions in hostile territory. It is operated by a two-person crew and extensively automated to reduce pilot workload.

Why was it used in the Iran strikes?

The B-2 Spirit was chosen for the Iran mission because of its unique combination of stealth, range, and payload capacity. The Fordow facility, built deep within a mountain and protected by sophisticated air defences, required a bomber that could both evade detection and deliver a bunker-busting payload with high precision.

During the mission, the B-2s were reportedly equipped with the GBU-57A/B Massive Ordnance Penetrator (MOP) — a 30,000-pound bomb specifically designed to destroy deeply buried and fortified targets like Fordow. Due to the weapon’s size and weight, a B-2 can carry only one or two MOPs per sortie. Reports indicate that six MOPs were dropped on Fordow, demonstrating the operational effectiveness of the B-2 for such critical missions.

Capabilities and Strategic Role

The B-2 has an unrefueled range of over 6,000 nautical miles (approximately 11,000 km), enabling it to undertake intercontinental missions directly from the United States. Past missions have seen the B-2 operate from Missouri to targets in Afghanistan, Libya, and now Iran, demonstrating its global strike capability.

With a total payload capacity exceeding 40,000 pounds (18,000 kg), the B-2 can carry both conventional and nuclear weapons. It forms a crucial part of the US nuclear triad, capable of delivering up to 16 B83 nuclear bombs. Its ability to carry nuclear and precision-guided munitions gives it unmatched strategic versatility.

Weapon Systems Compatible with the B-2

Beyond the MOP, the B-2 can be armed with a variety of precision and standoff weapons, including:

• JDAMs (Joint Direct Attack Munitions): GPS-guided bombs used for high-accuracy strikes on fixed targets.
• JSOW (Joint Standoff Weapons): Glide bombs launched from a distance, allowing engagement of targets outside enemy air defence range.
• JASSM and JASSM-ER (Joint Air-to-Surface Standoff Missiles): Long-range cruise missiles, with the extended-range variant capable of striking targets up to 500 miles (805 km) away.

This versatility allows the B-2 to adapt to multiple mission profiles, from conventional warfare to nuclear deterrence.

Strategic and Geopolitical Implications

The deployment of the B-2 in this mission has both tactical and symbolic implications. Tactically, it underscores the US military’s ability to deliver precision strikes on highly protected strategic infrastructure. Strategically, it sends a strong signal to adversaries about the technological edge and operational reach of American military power.

From a geopolitical perspective, the strikes could exacerbate tensions in the already volatile West Asian region, heighten concerns about nuclear proliferation, and potentially provoke retaliatory actions by Iran and its regional allies. It also raises questions about the future of US-Iran relations and the fragility of nuclear diplomacy in the region.

The United States Food and Drug Administration (FDA) on Wednesday approved Lenacapavir (LEN), the most promising HIV prevention medicine to be made so far.

What is Lenacapavir (LEN)?

• Type: Antiretroviral drug used as Pre-Exposure Prophylaxis (PrEP) for HIV prevention.
• Mechanism: Prevents HIV infection in HIV-negative individuals at high risk.
• Efficacy: Clinical trials show it prevents 99.9% of HIV transmissions.
• Dosage: Injectable form, administered twice a year.

Recent Development

• Approved by: United States Food and Drug Administration (US FDA) – June 2025.
• Brand name: To be marketed as Yeztugo by Gilead Sciences.
• Described as the most promising HIV prevention drug to date.

Global and Indian Context

Global Need

• LEN could be a game-changer in ending the global HIV/AIDS epidemic.
• However, cost remains a barrier—initially priced at over $40,000 per person/year, now reduced to $28,218.

Indian Reality

• Despite India's 92% contribution to global ART supply, PrEP is yet to be rolled out under India’s National AIDS Control Programme (NACP).
• The National AIDS Control Organisation (NACO) has not yet integrated PrEP or LEN into national policy.

India’s Role in Equitable Access

Expert View:

• India must take the lead in making LEN accessible, affordable, and timely.
• Equitable distribution is critical to preventing new infections and achieving AIDS elimination targets.
• Urges Indian regulators and generic companies to fast-track licensing and manufacturing.

Why this matter?

Public Health Impact

• LEN could stop HIV transmission at scale if made widely available in low- and middle-income countries (LMICs).
• Its twice-a-year injectable nature increases adherence, especially in vulnerable populations.

Cost Savings

• Prevention through PrEP like LEN is more cost-effective than providing lifelong ART after infection.

India’s Strategic Position

• India already serves as the global hub for HIV treatment through its generic pharmaceutical capacity.
• India’s leadership is central to global HIV prevention strategies including:
  • Treatment as Prevention (TasP)
  • Test and Treat
  • Post-Exposure Prophylaxis (PEP)
  • Pre-Exposure Prophylaxis (PrEP)

Policy Recommendations

• Fast-track regulatory approvals for generic LEN in India.
• Integrate PrEP and injectable LEN into NACO guidelines.
• Ensure price transparency and accessibility through public-private collaboration.
• Collaborate with global health bodies (WHO, UNAIDS, Global Fund) to position India as the equitable access leader.

Following the tragic crash of an Air India Boeing 787 Dreamliner from Ahmedabad to London Gatwick (June 2025), authorities have initiated DNA-based identification to match the remains of victims. In mass fatality incidents where bodies are mutilated or decomposed, DNA analysis becomes the gold standard for establishing identity.

What is DNA Identification?

DNA (Deoxyribonucleic Acid) is a unique genetic code present in almost every cell of the human body, with the exception of identical twins. It is widely used in forensic science for accurate identification, particularly in disasters where visual identification is impossible.

Sample Collection and Preservation:

• DNA begins degrading post-mortem, and the rate of degradation is influenced by:
  • Type of tissue (soft vs hard)
  • Environmental conditions (humidity, temperature)
• Hard tissues such as bones and teeth are preferred due to better preservation against decomposition.
• Soft tissues (like skin and muscle) degrade faster and, if used, must be stored in 95% ethanol or frozen at -20°C.
• In large-scale accidents, sample collection from wreckage can take weeks or even months (e.g., 9/11 took 10 months).

Reference Samples:

To match unidentified remains, reference DNA is taken from biological relatives—preferably parents or children of the victims, who share about 50% of their DNA.

Methods of DNA Analysis:

1. Short Tandem Repeat (STR) Analysis:

• Evaluates short, repeating DNA sequences that vary among individuals.
• Requires nuclear DNA, hence not suitable if the DNA is highly degraded.
• Analysis of 15+ hyper-variable STR regions can confirm family relationships with high accuracy.

2. Mitochondrial DNA (mtDNA) Analysis:

• Used when nuclear DNA is not recoverable.
• mtDNA is inherited exclusively from the mother and is present in multiple copies per cell.
• Effective for matching with maternal relatives (e.g., mother, maternal uncles/aunts, siblings).

3. Y-Chromosome Analysis:

• Targets male-specific genetic material.
• Useful for identifying remains using DNA from paternal male relatives (father, brothers, paternal uncles).
• Helpful when direct relatives are unavailable but male-line relatives exist.

4. Single Nucleotide Polymorphisms (SNPs) Analysis:

• Suitable when DNA is highly degraded.
• Analyzes variations at single base-pair locations in DNA.
• Can also match DNA with personal items like a toothbrush or hairbrush.
• However, less accurate than STR analysis.

Significance for Disaster Management and Forensics:

• DNA-based victim identification ensures scientific accuracy, aiding in closure for families, and upholding legal and humanitarian obligations.
• Modern forensic genetics has become an essential tool in mass disaster response protocols worldwide.

A recent study titled "Darkening of the Global Ocean", led by researchers from the University of Plymouth, has revealed that over 21% of the global ocean has darkened between 2003 and 2022, marking a significant environmental concern. The phenomenon, known as ocean darkening, is increasingly disrupting marine ecosystems and global climate regulation.

What is Ocean Darkening?

Ocean darkening refers to the reduction in the photic zone — the upper layer of the ocean (up to ~200 meters deep) where sunlight penetrates to support photosynthesis. This zone is foundational to:

• ~90% of marine biodiversity
• Climate regulation
• Ocean productivity
• Global fisheries

The study used satellite data and modeling based on the Diffuse Attenuation Coefficient (Kd 490), which measures how rapidly light fades through seawater. It found:

• 21% of global oceans experienced darkening in two decades.
• 9% saw photic depth decline by over 50 meters.
• 2.6% saw a reduction exceeding 100 meters — an area roughly equal to the size of Africa.

Geographic Distribution

• High darkening: Arctic, Antarctic, Gulf Stream, North Sea, eastern UK coast.
• Lesser darkening or even brightening: Some parts of the English Channel.
• The open ocean and climate-sensitive zones have witnessed the most pronounced declines.

Causes of Ocean Darkening

• Coastal Zones:
  • Runoff of agricultural nutrients, organic matter, and sediments.
  • Leads to algal blooms that block sunlight.
• Open Ocean:
  • Shifts in plankton dynamics
  • Rising sea surface temperatures
  • Altered ocean circulation patterns

These changes may be linked to climate change, land-use modifications, and increased rainfall-driven erosion.

Impact on Marine Ecosystems

Ocean darkening leads to:

• Shrinking habitats for light-sensitive species like Calanus copepods (key zooplankton and food web base).
• Disrupted feeding, migration, and reproduction cycles due to reduced solar and lunar light cues.
• Increased crowding in shallower waters, intensifying competition and predation.
• Collapse of marine food chains, even in areas with minimal fishing pressure.

Experts warn that this could represent one of the largest habitat losses in recent history, with implications for:

• Biodiversity
• Carbon cycling
• Oxygen production
• Ocean buffering against climate change

To combat rising cyber frauds and impersonation in the securities market, the Securities and Exchange Board of India (SEBI) has announced a verified Unified Payments Interface (UPI) ID system for all SEBI-registered market intermediaries. This mechanism, developed in coordination with the National Payments Corporation of India (NPCI), will be effective from October 1, 2025, and is part of SEBI’s broader agenda to enhance investor security and transparency.

Key Features:

• Exclusive UPI IDs: Only SEBI-registered intermediaries will be issued validated UPI IDs featuring a structured format: username.category@validBank. For example, a broker ABC Ltd using XYZ Bank would have the UPI ID: abc.brk@validXYZ.
• Category-Specific Suffixes:
  • .brk for stock brokers
  • .mf for mutual funds
• Authentication Visual Cue: Transactions with verified UPI IDs will display a “thumbs-up inside a green triangle” icon for easy identification by investors.

Role of NPCI

NPCI, which owns and operates the UPI platform, will exclusively allocate the “@valid” handles for payment collection by SEBI-registered intermediaries. This move ensures only authorised entities can use these UPI IDs, significantly reducing risks of fund misdirection.

SEBI Check Tool

To supplement the system, SEBI is also launching ‘SEBI Check’, a verification tool allowing investors to:

• Scan a QR code or enter UPI ID manually to confirm its legitimacy.
• Verify bank details, including account number and IFSC, of registered entities.

Investor and Intermediary Compliance

• Mandatory for Intermediaries: All SEBI-registered intermediaries must adopt the new verified UPI handles and educate investors about them.
• Optional for Investors: While the structured UPI handle is optional, investors must use only the new IDs if opting to pay via UPI.
• Discontinuation of Old IDs: Existing UPI IDs will be discontinued after October 1, 2025, except for ongoing SIPs (Systematic Investment Plans). New and renewed SIPs must use the verified UPI IDs.

Benefits

• Prevents Fraud: Eliminates payments to unauthorised or impersonating entities.
• Enhances Transparency: Clearly distinguishes registered entities from fraudulent ones.
• Boosts Investor Confidence: Assures secure transactions through verified payment channels.
• Supports Cybersecurity: Clamps down on fake UPI handles used for digital scams.

SEBI’s verified UPI ID initiative and the upcoming ‘SEBI Check’ tool are significant steps toward ensuring secure, transparent, and trustworthy digital transactions in India’s securities market. It reflects the regulator’s proactive stance in protecting investor interests in an increasingly digitised financial environment.

• Automation of Compensation: It will help automate claim processes, ensuring faster payments to farmers in case of crop failure.
• Rich Crop Signature Database: Repeated field observations will build a valuable dataset of crop images over time, useful for future agricultural planning and risk management.
• Farmer Involvement: By crowdsourcing photographs directly from farmers, CROPIC also encourages their direct participation in data collection.

How will CROPIC work on the ground?

• Data Collection via App:
  • A mobile app developed by the ministry will be used.
  • Farmers and officials will take photos of crops 4–5 times during a crop’s life cycle.
• AI-Based Analysis:
  • Photos will be processed on a cloud-based AI platform.
  • The model will identify crop type, growth stage, health condition, damage, and loss extent.
• Visualization and Monitoring:
  • A web-based dashboard will visualize crop status and damage patterns for stakeholders.
• Use in Insurance Claims:
  • The app will also be used by officials to collect photo evidence for PMFBY claims, helping streamline compensation payouts.

Project Timeline:

• Pilot Phase:
  • Begins with Kharif 2025 and Rabi 2025-26.
  • Will cover at least 50 districts per season, spanning various agro-climatic zones and major crops.
• Full Roll-Out: After initial R&D, nationwide implementation is planned from 2026 onwards.

Funding and Support:

• Funded through the Fund for Innovation and Technology (FIAT) under PMFBY.
• FIAT has a total allocation of ?825 crore for various tech-driven agricultural initiatives.

In News:

• The Central Pollution Control Board (CPCB) has recently introduced a new ‘Blue Category’ for industries under its Essential Environmental Services (EES) framework.
• Notably, Waste-to-Energy (WTE) incineration plants, previously classified as highly polluting ‘Red Category’ industries, have now been controversially reclassified under this new category.

Background: Pollution Index (PI) and Industry Categorisation

• The Ministry of Environment, Forest and Climate Change (MoEFCC) classifies industries into categories — White, Green, Orange, and Red — based on a Pollution Index (PI) (0–100 scale).
  • White (0–20): Least polluting
  • Green (21–40)
  • Orange (41–59)
  • Red (60–100): Most polluting
• WTE plants, with a PI of 97.6, were originally in the Red Category.

What is the new Blue Category?

• Created under Essential Environmental Services (EES) classification.
• Grants 2 additional years of “Consent to Operate” (essentially, consent to pollute).
• Aims to support infrastructure like composting units, biogas plants, material recovery facilities, etc

Controversy: WTE Incineration in the Blue Category

• WTE plants burn unsegregated municipal solid waste (MSW) to generate electricity by producing steam to drive turbines.
• Unlike claimed benefits, WTE plants emit more CO? per unit of electricity than coal-fired plants, contributing to climate change.
• CPCB’s inspection reports found that Delhi’s WTE plants exceeded emission norms, releasing carcinogens and other pollutants such as:
  • SOx, NOx, HCL, PM, Dioxins, and Furans
• In FY 2022–23, Delhi’s WTE plants incinerated ~735,840 tons of plastic, contributing significantly to Delhi’s poor air quality.
• These plants also generate hazardous ash, requiring secure landfill disposal.

Issues with Reclassification

• The CPCB’s own guidelines state that:
  • Only projects that do not emit hazardous waste or
  • Projects that promote the circular economy can be blue-listed.
• However, leading government institute CSIR-NEERI has observed that WTE plants violate the principles of the circular economy and contravene Solid Waste Management Rules, 2016.
• Reclassification undermines environmental safeguards, harms waste pickers’ livelihoods, and imposes financial burdens on Urban Local Bodies (ULBs).

About Nuclear Fusion Propulsion

Nuclear Fusion aims to replicate the process that powers stars — the fusion of atomic nuclei to release energy. Unlike nuclear fission, fusion is cleaner, offers higher energy output, and produces minimal radioactive waste.

Types of Nuclear Propulsion Systems

Propulsion Type                                                           Description

Nuclear Thermal Propulsion (NTP)             Uses a nuclear reactor to heat liquid hydrogen which

                                                                            turns to plasma and produces thrust. Provides high exhaust

                                                                            velocity and can increase payload efficiency 2–3 times

                                                                            over chemical rockets. Ground tests began in the 1950s.

Nuclear Electric Propulsion (NEP)                Converts reactor heat into electricity to power ion thrusters,

                                                                            which gradually reach high speeds. Components include a

                                                                                               compact reactor core, electric generator, heat rejection

                                                                                               system, and electric propulsion system. Unlike solar power,

                                                                           nuclear sources ensure consistent energy beyond Mars.

Challenges in Fusion Rocket Development

• Fusion systems are currently large and heavy, posing difficulties in miniaturisation for spaceflight.
• Fusion on Earth is hard to replicate due to atmospheric constraints; space offers a more natural environment for fusion reactions.

Global Efforts and Timeline

Apart from Pulsar Fusion, companies like Helicity Space and General Atomics (backed by NASA and Lockheed Martin) are also advancing fusion-powered space propulsion systems, with testing planned around 2027.

Recently, Ukraine conducted a major drone strike on Russia, reportedly destroying over 40 aircraft using First-Person View (FPV) drones—marking one of the deepest strikes into Russian territory since the start of the conflict in 2022. This highlights the growing role of FPV drones in modern asymmetric warfare.

What are FPV Drones?

First-Person View (FPV) drones are unmanned aerial vehicles (UAVs) that allow remote pilots to view the drone’s surroundings through a camera mounted on the drone. The live feed can be transmitted to:

• Specialized goggles
• Smartphones
• Other display screens

This immersive view enables highly precise navigation and control.

Key Features and Technologies

• GPS-Independent Navigation: Operates effectively even when GPS signals are jammed or unavailable.
• SmartPilot System: Uses visual-inertial navigation by interpreting camera data to assess the drone's position and orientation.
• LiDAR Integration: Enhances terrain mapping and obstacle detection in complex environments.
• Low Cost: A functional FPV drone can cost as little as $500, making them highly affordable compared to traditional weapon systems.

Operational Use in Combat

• Reconnaissance First: Typically, a long-range reconnaissance drone is used to identify the target area before deploying FPV drones for strikes.
• Deep Strike Capability: Despite having a short range (a few kilometres), FPV drones offer stealth and precision to strike deeply into enemy territory.
• Combat Strategy: Their agility and affordability make FPV drones a key component of attrition warfare, especially for resource-constrained nations.

Advantages in Warfare

• Cost-effectiveness: Offers high-impact capability at a fraction of the cost of conventional weapons.
• Reduced Human Risk: Limits the need for manned missions in hostile territory.
• Stealth: Smaller size and low acoustic footprint make them harder to detect and intercept.
• High Destructiveness: Able to carry payloads such as explosives, effectively targeting tanks, aircraft, and installations.

Challenges and Limitations

• Limited Range: Operates within a few kilometres, requiring deployment close to target zones.
• Reduced Situational Awareness: Pilots rely solely on camera feed, which may not provide full spatial context.
• Need for Visual Observers: In complex environments, an additional observer may be needed to guide the operator safely.

Ukraine’s Use of FPV Drones

Ukraine has effectively integrated FPV drones into its military strategy:

• In November 2023, FPVs were credited as a low-cost, high-impact method of resisting Russian advances.
• NATO sources indicated that over two-thirds of Russian tanks destroyed recently were hit by FPV drones.
• Ukrainian drone manufacturer Vyriy Drone delivered 1,000 indigenous FPVs in March 2025.
• Ukraine is projected to produce over 4 million drones in 2025, reflecting a significant scaling of domestic capabilities.

Geopolitical and Strategic Implications

• Technological Self-Reliance: Domestic production protects nations from geopolitical supply chain disruptions (e.g., China’s chip exports).
• Global Proliferation: Countries like Israel and Iran have also developed drone systems, including HAROP and Shahed drones respectively.

The Jharkhand government has proposed setting up its first-ever tiger safari in the fringe area of the Palamau Tiger Reserve (PTR), located in Latehar district. This initiative aims to promote wildlife education, conservation awareness, and eco-tourism, while also creating employment opportunities.

What is a Tiger Safari?

A tiger safari refers to a tourism model where rescued, conflict-prone, or orphaned tigers are housed in naturalistic enclosures, ensuring sightings for visitors. It differs from traditional wild safaris, where sightings are not guaranteed. The concept was first proposed in the NTCA's 2012 tourism guidelines, refined in 2016, and later aligned with the Supreme Court’s 2024 directive, which mandates that such safaris be located outside core and buffer zones of tiger reserves.

Legal and Regulatory Framework

• Governed by:
  • Wildlife (Protection) Act, 1972
  • National Tiger Conservation Authority (NTCA) Guidelines (2012, 2016)
  • Central Zoo Authority (CZA) for animal welfare, enclosure design, and project compliance
• Supreme Court Ruling (March 2024):
  • Tiger safaris must not be located inside core or buffer zones.
  • Intended to protect natural habitats and uphold conservation goals.

About Palamau Tiger Reserve (PTR)

• Established: 1974 under Project Tiger
• Location: Chhotanagpur Plateau, Jharkhand
• Rivers: North Koel, Burha (perennial), Auranga
• Vegetation: Northern Tropical Dry Deciduous forest (Sal-dominated)
• Key Fauna: Bengal Tiger, Asiatic Elephant, Sloth Bear, Leopard, Indian Pangolin, Otter
• Historical Note: Site of the world’s first pugmark-based tiger census (1932)

• Location: Barwadih Western Forest Range (fringe of PTR, outside core/buffer zones)
• Size: Approx. 150 hectares
• Animals Housed: Only rescued, conflict-prone, or orphaned tigers from reserves/zoos (not wild or zoo-bred tigers unless approved)
• Objectives:
  • Promote tourism and conservation education
  • Create an experiential learning space for visitors
  • Generate employment (~200 local jobs)

The Central Zoo Authority (CZA) will assess the site and species selection. Post Forest Department clearance, the Detailed Project Report (DPR) will be submitted to NTCA and CZA. Approvals may take 5–6 months, followed by a construction period of ~18 months.

Concerns and Challenges

• Tribal and Community Rights:Activists caution that such projects may marginalize forest-dwelling communities and restrict access to traditional forest-based livelihoods (grazing, NTFP collection).
• Consent of Local Communities:As per the Forest Rights Act, projects on forest land must involve Gram Sabha consultation. Activists argue this has yet to be fully addressed.
• State's Clarification:Officials maintain that the site lies on forest land under state management, with no expected displacement.

In News:

The Ministry of Statistics and Programme Implementation (MoSPI) released the Provisional Estimates (PEs) of India’s Gross Domestic Product (GDP) and Gross Value Added (GVA) for the financial year 2024–25 (FY25), providing a comprehensive picture of the country's economic performance.

Understanding GDP and GVA

• GDP (Gross Domestic Product) measures the total expenditure in the economy, including consumption, investment, government spending, and net exports — representing the demand side.
• GVA (Gross Value Added) evaluates the income generated from the production of goods and services in different sectors — representing the supply side.
• The two are related by the formula:GDP = GVA + Taxes – Subsidies
• Both are reported in nominal terms (current prices) and real terms (adjusted for inflation).

Nature of Provisional Estimates

• The estimates are termed provisional because they include data from all four quarters but are subject to revision:
  • First Advance Estimates (FAE): January
  • Second Advance Estimates (SAE): February
  • Provisional Estimates (PE): May
  • Revised Estimates: Finalized over the next two years (in 2026 and 2027 for FY25)

Key Economic Indicators for FY 2024–25

• Nominal GDP
  • Estimated at ?330.68 lakh crore, showing a 9.8% growth over FY24.
  • In dollar terms (?85.559/USD), India’s economy reached $3.87 trillion.
  • However, this 9.8% nominal growth marks the third-slowest since 2014.
