The Supreme Court of India has ruled that parental income alone cannot determine the “creamy layer” status of candidates belonging to the Other Backward Classes (OBCs) in civil services examinations. The judgment clarifies long-standing confusion in the implementation of reservation rules and emphasises that the creamy layer principle is primarily status-based rather than purely income-based.

Background of the Issue

The controversy arose due to conflicting government guidelines issued by the Department of Personnel and Training (DoPT).

• 1993 DoPT Office Memorandum (OM): Stated that income from salaries and agricultural land should not be included in the income/wealth test used to determine creamy layer status.
• 2004 DoPT Clarificatory Letter: Directed that salary income of employees working in Public Sector Undertakings (PSUs) and the private sector should be counted while determining the creamy layer.

This created a situation where:

• Children of government employees could retain OBC reservation based on the status of their parent’s post, even if salaries were high.
• Children of PSU or private sector employees could lose reservation benefits solely because their parental income crossed the prescribed threshold.

Key Observations of the Supreme Court

1. Creamy Layer Determination Must Be Status-Based

The Court held that creamy layer identification should focus on social and occupational status, not merely income.
Therefore, factors such as:

• Parent’s employment category (Group A, B, C, or D)
• Position and authority in the occupational hierarchy

should be considered along with income.

2. Quashing the 2004 Clarification

The Court set aside the 2004 DoPT clarification, stating that it created inconsistencies in applying reservation rules and contradicted the earlier 1993 guidelines.

3. Violation of Equality Principles

The Court held that the government’s earlier approach resulted in “hostile discrimination.”

• Children of lower-level government employees could still benefit from OBC reservation due to the status-based test.
• However, children of PSU or private sector employees with similar socio-economic positions were excluded solely due to salary levels.

This unequal treatment violated Articles 14, 15, and 16 of the Constitution, which guarantee equality before law and equal opportunity in public employment.

4. Relief for Affected Candidates

The judgment may expand eligibility for OBC reservation, particularly benefiting children of PSU employees, public sector bank employees, and private sector workers who were previously excluded due to income-based calculations.

The Court also directed the government to create supernumerary posts if required to accommodate candidates who were wrongly denied reservation benefits earlier.

Concept of the Creamy Layer

• The idea of excluding the more advanced sections among OBCs from reservation benefits was established in the landmark Indra Sawhney vs Union of India case.
• Objective: To ensure that reservation benefits reach socially and educationally backward sections, rather than the relatively advanced members within OBC communities.

Existing Criteria for Creamy Layer

• Government Employees
  1. Children of Group A officers are automatically considered part of the creamy layer.
  2. Children of officers promoted to Group A before the age of 40 are also excluded.
  3. Children of two Group B officers fall under the creamy layer.
• Non-Government Occupations: For those employed in the private sector or other professions, the income threshold for creamy layer is ?8 lakh per annum (since 2017).

Significance of the Judgment

• Clarifies reservation policy: Removes ambiguity in determining creamy layer status.
• Ensures equality: Prevents discriminatory treatment between government employees and those in PSUs or the private sector.
• Strengthens constitutional principles: Reinforces the guarantees of Articles 14, 15, and 16.
• Promotes fair access to reservations: Ensures benefits reach genuinely disadvantaged groups.

The Supreme Court of India has directed the Union Government to formulate a “no-fault liability compensation policy” for individuals who suffered serious adverse effects or deaths following Covid-19 vaccination during India’s nationwide immunisation programme. The Court held that victims or their families should receive compensation without having to prove negligence by the State or vaccine manufacturers.

Key Observations of the Supreme Court

1. Principle of No-Fault Liability

The Court invoked the no-fault liability principle, which allows compensation to victims without establishing fault or wrongdoing.

• The principle already exists in Indian law in areas such as motor vehicle accident compensation.
• Similar vaccine injury compensation schemes operate in countries such as Australia, the United Kingdom, and Japan.

This framework ensures speedy and equitable relief for victims of rare but serious vaccine side effects.

2. Rejection of Individual Litigation

The Union Government had argued that affected families could approach civil courts or consumer courts for damages against manufacturers or the State.

However, the Court rejected this argument, stating that:

• Individual litigation would lead to multiple legal battles.
• It could produce inconsistent outcomes and unequal access to justice.
• Such a situation may violate the Right to Equality under Article 14 of the Constitution.

3. State’s Positive Obligation

• Invoking Article 21 (Right to Life and Health), the Court emphasised that the State must act as an active guardian of citizens’ welfare and dignity.
• Since the vaccination drive was a State-led public health intervention, the government has a positive obligation to support those who suffer serious outcomes, even if such events are extremely rare.
• For instance, certain blood-clotting disorders associated with vaccines were reported at an estimated rate of about 0.001 per one lakh doses in India.

4. Compensation Beyond Surveillance

The Court observed that monitoring adverse events alone is insufficient. India already has a mechanism for investigating vaccine side effects through Adverse Events Following Immunisation (AEFI) committees.

The Court ruled that:

• These committees are adequate for medical assessment.
• However, the State’s responsibility cannot end with surveillance and investigation; it must extend to fair financial compensation.

5. Clarification on Liability

The Court clarified that creating a compensation policy does not amount to an admission of legal liability by the Union Government or vaccine manufacturers. Rather, it is a welfare-oriented public health measure.

Background: Earlier Judicial Interventions

1. Gaurav Kumar Bansal vs Union of India (2021)

The Supreme Court directed the National Disaster Management Authority (NDMA) to recommend guidelines for ex-gratia assistance for Covid-19 deaths.

Following this:

• NDMA fixed ?50,000 compensation per Covid-19 death.
• Payment was to be made by states through the State Disaster Response Fund (SDRF).
• A simplified procedure recognised deaths occurring within 30 days of a positive test as Covid-19 deaths.
• District-level grievance redressal committees were established to resolve disputes related to death certificates.

2. Jacob Puliyel vs Union of India (2022)

In this case, the Supreme Court:

• Upheld the validity of the Covid-19 vaccine approval process and the government’s AEFI monitoring system.
• Recognised bodily autonomy under Article 21, stating that no individual can be forcibly vaccinated.

Significance of the Judgment

• Strengthens public health governance: Encourages trust in vaccination programmes by ensuring protection for rare adverse outcomes.
• Ensures equitable relief: Avoids lengthy and costly litigation for affected families.
• Balances public interest and individual rights: Recognises both the importance of mass vaccination and the rights of individuals who suffer harm.
• Aligns India with global practices: Many countries already operate vaccine injury compensation programmes.

In News:

• The NITI Aayog has released the second edition of the Fiscal Health Index (FHI) 2026, which evaluates the fiscal performance and sustainability of Indian states for the financial year 2023–24.
• The index provides a comprehensive framework to assess the fiscal strength, vulnerabilities, and sustainability of state finances, moving beyond traditional indicators such as fiscal deficit to a broader evaluation of fiscal management.
• Given that state governments account for around one-third of India’s general government debt, their fiscal health plays a critical role in ensuring macroeconomic stability and sustainable economic growth.

What is the Fiscal Health Index?

• The Fiscal Health Index (FHI) is a comparative analytical framework developed by NITI Aayog to evaluate the financial performance of states using multiple fiscal indicators. It aims to promote transparent fiscal governance, data-driven policymaking, and peer benchmarking among states.

Key Pillars of the Index

The FHI evaluates states based on five core pillars:

• Quality of Expenditure: This indicator examines the composition of government spending, focusing on the proportion allocated to developmental and capital expenditure rather than committed or routine spending.
• Revenue Mobilisation: It measures the ability of states to generate own tax and non-tax revenues, reflecting fiscal self-reliance.
• Fiscal Prudence: This pillar evaluates how effectively states manage their fiscal deficits and adhere to the norms under the Fiscal Responsibility and Budget Management Act (FRBM).
• Debt Index: It assesses the size and burden of outstanding liabilities, indicating the level of indebtedness.
• Debt Sustainability: This dimension examines the long-term ability of states to service their debt obligations without creating fiscal stress.

State Rankings (FY 2023–24)

Top Performing States

1. Odisha – Rank 1 (Score: 73.1)
2. Goa – Rank 2 (Score: 54.7)
3. Jharkhand – Rank 3 (Score: 50.5)
4. Gujarat – Rank 4
5. Maharashtra – Rank 5

Bottom Performing States

• Punjab – Rank 18
• Andhra Pradesh – Rank 17
• West Bengal – Rank 16
• Kerala – Rank 15

Among the North-Eastern and Himalayan states, Arunachal Pradesh emerged as the top performer, largely due to high-quality expenditure and relatively stable fiscal management.

Key Findings of the Report

• Expanded Coverage: The 2026 edition expanded its scope to include 10 North-Eastern and Himalayan states, recognising their unique geographic and structural fiscal constraints.
• Improved Capital Expenditure: Several states have increasingly prioritised capital expenditure and social sector spending, reflecting a shift toward growth-oriented investments.
• Persistent Fiscal Stress in Some States: Certain states continue to face structural fiscal challenges, including rising debt levels, weak revenue growth, and high fiscal deficits.
• Importance for National Macroeconomic Stability: With state finances forming a significant portion of public debt, improving fiscal management at the state level is essential for India’s overall fiscal stability.

Major Challenges Highlighted

• High Committed Expenditure: Large portions of state budgets are locked into salaries, pensions, and interest payments, leaving limited resources for development. For example, committed expenditure in Punjab accounted for about 80% of revenue receipts in 2023–24.
• Weak Own-Revenue Mobilisation: Several states depend heavily on central transfers rather than internal revenue generation. In Bihar, own revenue contributes less than one-third of total receipts, increasing fiscal vulnerability.
• Fiscal Deficit Pressures: Some states have breached the fiscal deficit limits prescribed under the FRBM framework. For instance, Andhra Pradesh’s fiscal deficit reached 4.35% of GSDP in 2023–24, exceeding the recommended threshold.
• Rising Interest Burden: High levels of debt lead to large interest payments. West Bengal spends over 20% of its revenue receipts on debt servicing, reducing fiscal flexibility.
• Geographic Constraints: States with challenging terrain face higher infrastructure and service delivery costs. For example, Himachal Pradesh experiences fiscal stress due to the high cost of maintaining infrastructure in mountainous regions along with rising pension liabilities.

Way Forward

To strengthen fiscal sustainability, the report suggests several reforms:

• Broadening the tax base and improving GST compliance to enhance state revenue capacity
• Rationalising subsidies and committed expenditure to create fiscal space for development
• Increasing the quality of capital expenditure to generate long-term economic growth
• Adopting medium-term fiscal frameworks to manage deficits and debt trajectories
• Enhancing transparency and data-driven governance, using tools such as the Fiscal Health Index for benchmarking

Location and Geographic Setting

• Devon Island is located in the Canadian Arctic Archipelago within the territory of Nunavut, Canada, and lies well within the Arctic Circle.
• It is recognized as the largest uninhabited island on Earth, characterized by extremely harsh climatic conditions and limited biological activity.

Neighbouring Regions

• North: Separated from Ellesmere Island by Jones Sound
• South: Separated from Somerset Island and Baffin Island by Lancaster Sound
• West: Cornwallis Island, home to the settlement of Resolute
• East: Baffin Bay

Climate and Environmental Conditions

Devon Island is classified as a polar desert, characterized by extremely low precipitation and harsh climatic conditions.

Key climatic features include:

• Short growing season: Approximately 40–55 days per year
• Summer temperatures: Around 2°C to 8°C
• Winter temperatures: Can fall to −50°C
• Low solar energy input and minimal rainfall

These conditions severely limit vegetation growth, resulting in a barren, rocky landscape covered by snow and ice for much of the year.

Major Geographic Features

Haughton Impact Crater

• A prominent feature of the island is the **Haughton Impact Crater, approximately 20 kilometres (14 miles) wide, formed about 39 million years ago when a meteorite struck the region.
• The crater’s rocky, fragmented terrain and absence of vegetation make it one of the closest terrestrial analogues to the cratered surface of Mars.

Following airstrikes on oil storage facilities in Tehran and Alborz Province in early March, residents reported the occurrence of “black rain”, a rare environmental phenomenon in which rainfall becomes contaminated with pollutants such as soot, hydrocarbons, and toxic chemicals. The event highlighted the severe environmental and health risks associated with large-scale industrial fires and atmospheric pollution.

What is Black Rain?

Black rain refers to precipitation that becomes heavily contaminated with soot, hydrocarbons, and chemical pollutants present in the atmosphere. Unlike normal rainwater, black rain appears dark, oily, and chemically polluted, often leaving a layer of toxic residue on surfaces.

This phenomenon generally occurs when dense smoke and particulate matter from fires mix with rain clouds, causing the falling rain droplets to absorb pollutants from the surrounding air.

Formation Process

The formation of black rain typically involves several atmospheric processes:

•  and Smoke Generation: Large fires, especially from oil refineries or fuel storage facilities, release thick plumes of smoke containing soot and chemical vapours into the atmosphere.
• Atmospheric Loading: The smoke carries high concentrations of particulate matter and toxic gases, which accumulate in the lower atmosphere.
• Coalescence with Rain Clouds: When rainfall occurs, the raindrops pass through polluted air layers, absorbing suspended particles and chemicals before reaching the ground.
• Topographical Influence: In cities surrounded by mountains, such as Tehran, topographic barriers can trap smoke and pollutants, preventing dispersion and increasing the likelihood of contaminated rainfall.

Chemical Components

Black rain can contain a mixture of hazardous substances, including:

• Toxic hydrocarbons, such as benzene, which is a known carcinogen
• Sulphur oxides (SOx) and nitrogen oxides (NOx), which can react with water vapour to produce acid rain
• Particulate matter (soot) composed of carbon particles
• Per- and polyfluoroalkyl substances (PFAS) or “forever chemicals,” often released from industrial fire-suppression systems

These pollutants combine with rainwater to form a chemically contaminated precipitation.

Key Characteristics

Black rain exhibits distinct physical properties compared to normal rainfall:

• Appearance: Dark or jet-black droplets that may stain surfaces permanently
• Odour: Strong smell of burning petroleum and chemicals
• Texture: Greasy or viscous due to hydrocarbon contamination
• Spread: Polluted rainfall can fall many kilometres away from the original fire site depending on wind direction and atmospheric circulation

Environmental and Health Implications

Health Risks

Exposure to contaminated rainfall may cause:

• Skin irritation and burns
• Eye irritation
• Respiratory disorders due to inhalation of toxic particles
• Long-term risks such as lung damage or cancer from carcinogenic chemicals

Environmental Contamination

Pollutants deposited by black rain can contaminate soil and groundwater, potentially entering the food chain through crops and livestock.

Acid Rain Effects

The presence of sulphur and nitrogen oxides may lead to acidic precipitation, which can damage:

• Vegetation and crops
• Buildings and monuments
• Urban infrastructure

Persistent Pollution

Certain chemicals such as PFAS are highly persistent in the environment and may remain in soil and water for decades, posing long-term ecological challenges.

• Scientists from ETH Zurich and the Technical University of Munich have developed a novel method to engineer bacteria to produce customised “designer proteins” using artificial amino acids.
• The breakthrough enables microorganisms to synthesize proteins with new biological and chemical properties, opening possibilities for advanced drug delivery systems and next-generation biotechnology applications.
• The research focuses on modifying nutrient transport mechanisms in bacteria such as Escherichia coli (E. coli) so that cells can efficiently import artificial amino acids required to build synthetic proteins.

Nutrient Transporter Proteins

• A nutrient transporter protein is a membrane-bound protein that facilitates the movement of essential molecules such as amino acids, peptides, and other nutrients—across the cell membrane.
• In the recent research, scientists engineered a specialized ABC (ATP-Binding Cassette) transporter in bacteria. Normally, this transporter imports small peptide molecules used as nutrients. By modifying it, researchers enabled bacterial cells to import peptides carrying artificial amino acids, which can then be used to assemble customised proteins.

Objective of the Research

• The main goal of the study was to enable cells to incorporate artificial amino acids into proteins efficiently. Natural proteins are typically built from 20 standard amino acids, but introducing synthetic amino acids allows scientists to design proteins with new functional properties.
• However, artificial amino acids generally cannot easily cross the cell membrane. By engineering a transporter protein capable of importing these molecules, researchers overcame a major barrier in synthetic biology and protein engineering.

Mechanism of the System

The engineered system works through a multi-step biological process:

1. Engineering of ABC Transporter – Scientists modified the transporter protein to improve its ability to import peptides containing artificial amino acids.
2. Trojan Horse Strategy – Artificial amino acids are concealed inside short peptide chains such as tripeptides or tetrapeptides composed of natural amino acids.
3. Transport into the Cell – The transporter imports these peptide chains across the cell membrane.
4. Release of Artificial Amino Acids – Once inside the cell, enzymes break the peptides into individual amino acids.
5. Protein Synthesis – The ribosome, the cellular machinery responsible for protein production, incorporates the artificial amino acids into newly synthesized proteins.

Through this approach, bacterial cells can generate custom-designed proteins on demand.

Key Innovations

• Trojan Horse Delivery Strategy: Artificial amino acids are hidden within natural peptide structures, allowing them to bypass cellular membrane barriers and enter the cell.
• Engineered ABC Transporter: The modified transporter is capable of importing up to ten times more artificial amino acids compared to natural transport systems.
• Directed Evolution: Researchers used directed evolution, a technique that mimics natural selection in the laboratory, to improve the efficiency of the transporter protein under nutrient-rich conditions.
• Multifunctional Protein Design: The system allows two different artificial amino acids to be incorporated into a single protein, enabling complex and multifunctional molecular designs.
• Compatibility with Standard Laboratory Conditions: The engineered bacteria can function effectively in standard laboratory growth media, making the system practical for widespread scientific use.

The Government of India has informed the Lok Sabha that Kavach 4.0, India’s indigenous Automatic Train Protection (ATP) system, has been successfully commissioned across 1,452 route kilometres on the high-density Delhi–Mumbai Railway Corridor and Delhi–Howrah Railway Corridor.

The system represents a major technological advancement aimed at improving railway safety and reducing accidents caused by human error. Kavach forms a crucial part of the modernization and safety enhancement efforts of Indian Railways.

What is Kavach?

• Kavach is an indigenously developed Automatic Train Protection (ATP) system designed to prevent train collisions and ensure safer railway operations. It is a sophisticated electronic safety mechanism that automatically monitors train movement and intervenes when necessary.
• The system has been developed by the Research Design and Standards Organisation (RDSO) in collaboration with domestic industry partners, reflecting India’s push toward self-reliance in railway technology.

Objectives of Kavach

The primary objective of Kavach is to achieve “Zero Accidents” in railway operations by addressing key safety risks.

Major goals include:

•  Signal Passing at Danger (SPAD), where a train crosses a stop signal.
• Controlling overspeeding of trains.
• Ensuring safe operations during adverse weather conditions, especially dense fog.
• Reducing accidents caused by human error.

Working Mechanism

Kavach operates through an integrated communication and monitoring network that continuously tracks train movement and signal conditions.

The system functions through the following components:

• RFID tags installed along railway tracks
• On-board equipment installed in locomotives
• Radio communication towers at railway stations

These components exchange real-time data regarding the train’s speed, location, and signal status. If the system detects a possible collision, signal violation, or overspeeding, it automatically activates the braking system, even if the loco pilot fails to respond.

Key Features of Kavach 4.0

The Kavach 4.0 version introduces several technological improvements for better reliability and precision.

• Enhanced Precision: The system offers improved location accuracy and better processing of signal information, particularly in complex railway yards and high-density corridors.

A male Blue-and-White Flycatcher, a rare migratory bird in India, was recently recorded on the Pavagadh Hills in Gujarat. The sighting is significant because the species is seldom observed in the Indian subcontinent, highlighting the ecological importance of hill and forest habitats that occasionally serve as stopover sites for migratory birds.

About the Blue-and-White Flycatcher

The Blue-and-White Flycatcher is a migratory songbird belonging to the Old World flycatcher family (Muscicapidae).

• Scientific Name: Cyanoptila cyanomelana
• Common Name: Japanese Flycatcher
• Type: Small insectivorous migratory bird

Flycatchers are known for their agile aerial movements and their ability to catch insects mid-flight, which makes them important for natural pest control and ecological balance.

Geographic Distribution and Migration

The Blue-and-White Flycatcher is mainly distributed in East and Southeast Asia.

Breeding Range

• Japan
• South Korea
• Northeastern China
• The Russian Far East

Wintering Range

• Vietnam
• Cambodia
• Thailand
• Islands such as Sumatra and Borneo

During migration, individual birds may occasionally appear outside their normal range, which explains rare sightings in India such as the one in Gujarat.

Habitat

The species typically inhabits forested landscapes and prefers:

• Wooded lowlands
• Submontane forests
• Taiga-like environments
• Wooded slopes and gullies

It is usually found at elevations up to about 1,200 metres. The bird may also adapt to scrublands, bushes, and plantation areas, especially during migration.

Physical Characteristics

The Blue-and-White Flycatcher exhibits sexual dimorphism, meaning males and females have distinct appearances.

Male

• Upper body covered in bright cobalt-blue plumage
• Blue coloration on wings, tail, and upperparts
• Black chin, throat, breast, and flanks
• White belly and vent
• Black bill and dark brown eyes

Female

• Grey-brown upperparts, including head and face
• Blackish wings with rufous-brown edges on tertial feathers
• Grey to grey-brown chin and throat
• Cream-coloured throat patches

These differences help birdwatchers distinguish between sexes in the field.

According to the International Union for Conservation of Nature (IUCN) Red List, the Blue-and-White Flycatcher is classified as Least Concern.

Despite its stable global population, the species still depends on healthy forest ecosystems and migratory corridors for survival.

In News:

• India has selected Visakhapatnam, Andhra Pradesh, as the site for establishing a high-energy proton accelerator system to support its long-term nuclear energy strategy.
• The project will play a crucial role in advancing the Accelerator-Driven System (ADS) technology, which is central to India’s effort to utilise its vast thorium reserves and enhance nuclear safety.
• The initiative is being developed by the Raja Ramanna Centre for Advanced Technology (RRCAT) located in Indore, Madhya Pradesh.
• Visakhapatnam was chosen because of its strong technological ecosystem, availability of research infrastructure, and proximity to the sea, which ensures sufficient cooling water for operating high-energy accelerator systems.

High-Energy Proton Accelerator System

A high-energy proton accelerator is a scientific device that uses electromagnetic fields to accelerate protons (positively charged particles from ionised hydrogen) to extremely high speeds. The accelerated protons form a powerful proton beam that is directed toward a heavy metal target such as lead or bismuth.

When the high-speed protons collide with the heavy metal nucleus, a process known as spallation occurs. In this reaction:

• The heavy nucleus breaks apart due to the impact.
• A large number of high-energy neutrons are released.
• These neutrons can then be used to initiate nuclear fission reactions in a reactor system.

Thus, the proton accelerator becomes an external source of neutrons required for controlled nuclear reactions.

Accelerator-Driven System (ADS)

The Accelerator-Driven System is a nuclear reactor concept in which the neutron supply required for fission is provided externally by a proton accelerator.

Key features of ADS include:

• The reactor core remains sub-critical, meaning it cannot sustain a chain reaction independently.
• The spallation neutrons generated by the proton accelerator are injected into the reactor core to maintain fission.
• If the accelerator stops functioning due to a power outage or malfunction, the neutron supply ceases immediately.

This design provides high inherent safety, as the nuclear reaction automatically stops without external intervention, significantly reducing the risk of reactor meltdown.

Role of ADS in India’s Three-Stage Nuclear Programme

• India’s nuclear energy strategy follows a three-stage programme aimed at maximising the utilisation of its limited uranium resources and abundant thorium deposits.
• ADS technology supports the third stage of this programme, which focuses on thorium-based nuclear energy.

Harnessing Thorium Resources

India possesses around 25% of the world’s thorium reserves, primarily in monazite sands along its coastal regions. However, naturally occurring Thorium-232 is fertile rather than fissile, meaning it cannot directly sustain a nuclear chain reaction.

For thorium to become a usable nuclear fuel:

1. Thorium-232 must absorb a neutron.
2. It undergoes nuclear transformation (transmutation).
3. It converts into Uranium-233, which is a highly fissile material capable of sustaining nuclear reactions.

The high-energy neutrons generated by the ADS system are particularly effective in facilitating this conversion, enabling thorium to become a viable fuel for large-scale electricity generation.

Nuclear Waste Management

Another major advantage of ADS technology lies in nuclear waste transmutation.

Conventional nuclear reactors generate long-lived radioactive waste, including minor actinides, which remain hazardous for thousands of years. ADS systems can use high-energy neutrons to:

• Break down long-lived radioactive isotopes
• Convert them into shorter-lived or stable elements

This process significantly reduces the toxicity and storage duration of nuclear waste, thereby addressing one of the major environmental concerns associated with nuclear power.

• Recently, the National Highways Authority of India (NHAI) released the first National Highways Green Cover Index (NH-GCI), a scientific framework to assess and monitor vegetation cover along India’s national highways.
• The index has been developed in collaboration with the National Remote Sensing Centre (NRSC), a centre of the Indian Space Research Organisation (ISRO).
• The initiative represents a significant step toward environmentally sustainable highway development, enabling data-driven monitoring of plantations and greenery along highway corridors.

About the NH-GCI

• The National Highways Green Cover Index is a satellite-based assessment tool that measures the extent of vegetation along the Right of Way (RoW) of national highways.
• Objective: To provide a scientific and quantitative evaluation of green cover along the national highway network using advanced space-based technologies.
• Coverage:
  • The first assessment covers around 30,000 km of National Highways across 24 states for the period July–December 2024.
  • The index evaluates vegetation present along the left and right sides of highways as well as the median, wherever plantation is feasible.
• Methodology: The NH-GCI uses advanced remote-sensing techniques to estimate vegetation density and distribution.
  • Satellite Data: High-resolution satellite sensors are used to detect chlorophyll content in vegetation.
  • NDVI Analysis: The assessment relies on the Normalized Difference Vegetation Index (NDVI) derived from satellite imagery. NDVI measures vegetation health and density based on the reflection of light from plant chlorophyll.
  • Segment-wise Assessment: Analysis is carried out for every 1-km segment of national highways, allowing precise monitoring of green cover across the network.

Through this methodology, the index provides consistent and objective measurements of vegetation along highway corridors.

• Recently, the Forest Survey of India (FSI) discontinued the AI-based Anavaran Deforestation Alert System, which had been issuing fortnightly alerts to states on forest cover loss.
• The portal has not been updated since November 2025, and state forest departments reportedly stopped receiving alerts thereafter. The system had been functioning as a pilot project, and its continuation is currently under review.
• The halt of the alert system has raised concerns among forest officials and environmental experts as it was considered an important near-real-time monitoring tool for detecting deforestation and guiding field inspections.

About the Anavaran Portal

• The Anavaran Deforestation Alert System was launched in January 2024 to strengthen forest monitoring in India through advanced geospatial technology and artificial intelligence. It aimed to provide location-specific alerts on forest cover loss every 15 days, enabling state forest departments to conduct targeted ground verification and enforcement actions.
• During its operational period from January 2024 to October 2025, the system generated 12,351 deforestation alerts, averaging about 561 alerts per month, which increased to over 1,000 alerts per month during the peak deforestation season between November and March.
• The alerts helped authorities detect potential activities such as illegal logging, encroachment, and land-use change in forest areas, enabling quicker administrative responses.

Technology Used in the System

The Anavaran system relied on advanced remote sensing and data-processing tools to monitor forest cover changes.

• Google Earth Engine (GEE): The portal was developed on the cloud-based geospatial platform Google Earth Engine, which enables large-scale processing of satellite imagery.
• Sentinel-2 Satellite Data: High-resolution optical images from the Sentinel-2 satellites were used to detect vegetation loss and land-cover changes.
• Sentinel-1 Synthetic Aperture Radar (SAR): Radar data from Sentinel-1 satellites was integrated to monitor forests even during cloudy and monsoon conditions, when optical satellite imagery becomes less effective.

Through machine-learning algorithms, the system analysed these datasets to identify potential forest cover changes and automatically generate alerts for authorities.

Forest Survey of India (FSI)

The Forest Survey of India is the premier national organization responsible for monitoring forest resources in the country. It functions under the Ministry of Environment, Forest and Climate Change.

• Established: 1 June 1981
• Predecessor: Pre-investment Survey of Forest Resources (PISFR), a project initiated in 1965 with support from the FAO and UNDP.
• Mandate: Assessment and monitoring of forest resources, research, training, and technical support to states.
• Key Publication: The India State of Forest Report (ISFR), published biennially since 1987, which assesses forest and tree resources using remote sensing data and the National Forest Inventory (NFI).

According to the latest ISFR assessment, India’s forest and tree cover stands at about 8,27,357 sq km (25.17% of the geographical area).

The European Space Agency (ESA) recently lost communication with the Coronagraph spacecraft, one of the two satellites of the Proba?3 Mission, following an anomaly that triggered a power failure and pushed the spacecraft into a protective “survival mode.” The incident occurred after the spacecraft experienced an unexpected drop in solar power, temporarily halting operations and causing the loss of telemetry signals. Engineers are attempting to re-establish contact and recover the satellite.

About the Proba-3 Mission

• Proba-3 is an advanced solar-observation mission launched in December 2024 by ESA aboard PSLV?C59 developed by the Indian Space Research Organisation.
• It is considered the world’s first precision formation-flying mission, designed to study the Sun’s outer atmosphere, known as the corona, with unprecedented clarity.

Objective

The primary objective of the mission is to create an artificial solar eclipse in space. By blocking the Sun’s bright disk, scientists can directly observe the faint corona for extended durations—something that is otherwise possible only for a few minutes during natural total solar eclipses.

Key Features of the Mission

1. Twin-Spacecraft Configuration: The mission consists of two independent satellites working in coordination:

• Occulter spacecraft – carries a disk that blocks sunlight.
• Coronagraph spacecraft – carries the telescope and camera to observe the corona.

2. Precision Formation Flying: The two satellites maintain a distance of about 150 metres with millimetre-level accuracy, effectively functioning as a single large virtual instrument in space.

3. Artificial Eclipse Mechanism: The Occulter blocks the Sun’s bright disk and casts a precise shadow onto the Coronagraph’s optical instrument, replicating the conditions of a total solar eclipse in space.

4. Autonomous Coordination: The satellites rely on laser sensors, cameras, and cold-gas thrusters to autonomously adjust their relative positions without continuous ground control intervention.

5. Continuous Solar Observations: Before the anomaly occurred, the mission had successfully completed over 60 orbital cycles, producing hours of uninterrupted solar observations—far longer than ground-based eclipse observations.

Recent reports indicate that Iran struck a radar associated with the Terminal High Altitude Area Defense (THAAD) system used by the United States and Israel in West Asia. The incident highlights the strategic importance of advanced missile defence systems in regions experiencing heightened geopolitical tensions.

About the THAAD System

THAAD is an advanced ballistic missile defence system developed by the United States to intercept and destroy short-, medium-, and limited intermediate-range ballistic missiles. It forms a critical component of the U.S. layered missile defence architecture.

The system is designed to neutralise incoming ballistic missiles during the terminal phase of their trajectory, which is the final stage of a missile’s flight before it reaches its target.

Key Features

• High-Altitude Interception
  • THAAD can intercept ballistic missiles at ranges of around 150–200 km.
  • It is capable of destroying targets both inside and outside the Earth’s atmosphere, providing a high-altitude defensive shield.
• Terminal Phase Defence: The system targets missiles during their terminal descent, when the warhead approaches the target area.
• Hit-to-Kill Technology
  • THAAD interceptor missiles rely on kinetic energy to destroy targets through direct impact, rather than using explosive warheads.
  • This improves accuracy and reduces the risk of collateral damage.
• Integrated Radar and Command System: The system uses powerful radar and command-and-control networks to detect, track, and engage incoming missile threats.

Global Deployment

Several countries have adopted THAAD as part of their missile defence strategies.

• The United Arab Emirates became the first foreign buyer in 2011.
• Saudi Arabia later procured the system to strengthen its air and missile defence capabilities.

These deployments reflect increasing concerns in the region regarding ballistic missile threats.

A recent report by Human Rights Watch has accused Israel of using white phosphorus munitions in residential areas of Lebanon, raising concerns about possible violations of international humanitarian law. The allegations come amid escalating hostilities along the Israel–Lebanon border, with Lebanese authorities reporting significant civilian casualties from recent strikes.

What is White Phosphorus?

White phosphorus (WP) is a highly reactive chemical substance commonly used in military operations. It appears as a translucent yellowish-white waxy solid that glows faintly when exposed to oxygen due to slow oxidation.

Key characteristics include:

• Highly flammable: Burns at temperatures exceeding 800°C, hot enough to melt metal.
• Persistent combustion: Continues burning until the chemical is completely consumed or deprived of oxygen.
• Storage conditions: Usually stored under water or inert environments to prevent accidental ignition.
• Odour: Often described as having a garlic-like smell.

Military Uses of White Phosphorus

White phosphorus is mainly used for military tactical purposes, including:

1. Smoke Screens: Produces dense smoke that can obscure troop movements or equipment.
2. Illumination: Used in flares to light up battlefields at night.
3. Incendiary Effects: Can ignite objects and structures due to intense heat.

Because of these functions, it is often categorized as an incendiary munition, which refers to weapons designed to set fire to objects or cause burn injuries through heat, flames, or chemical reactions.

Health and Environmental Hazards

The use of white phosphorus poses severe risks to human health, particularly in populated areas.

Major health impacts include:

• Deep chemical burns that may penetrate to the bone.
• Release of toxic chemicals damaging organs such as the liver, kidneys, and heart.
• Metabolic disorders, including abnormal potassium levels that may lead to cardiac failure.
• Increased risk of building fires and infrastructure destruction when used in civilian areas.

These effects make its deployment in urban environments especially dangerous for civilians.

Legal Status under International Law

White phosphorus is not explicitly banned under the Chemical Weapons Convention when used for non-chemical warfare purposes such as smoke generation. However, its use is regulated by international humanitarian law.

The Convention on Certain Conventional Weapons (CCW) restricts weapons that cause excessive injury or indiscriminate harm.

• Protocol III of the CCW specifically restricts the use of incendiary weapons against civilians or in civilian-populated areas.
• However, white phosphorus is often classified as a multi-purpose munition used for smoke or illumination, enabling some militaries to argue that it does not fall strictly under incendiary weapon restrictions.
• Israel is not a signatory to Protocol III, complicating enforcement and accountability.

Notably, India is a party to all five protocols of the CCW, reflecting its commitment to regulating conventional weapons that cause indiscriminate harm.

The Reserve Bank of India (RBI) recently conducted Open Market Operation (OMO) purchase auctions of Government Securities (G-Secs) worth ?50,000 crore to inject liquidity into the banking system. The move was undertaken amid pressure on the Indian rupee and tight liquidity conditions in the financial system. OMOs are an important monetary policy tool used by the RBI to regulate liquidity and maintain stability in financial markets.

What are Open Market Operations (OMO)?

Open Market Operations refer to the purchase and sale of government securities by the RBI in the open market to manage liquidity in the banking system.

Types of OMOs:

• OMO Purchase
  • RBI buys government securities from banks or financial institutions.
  • This injects liquidity into the banking system as banks receive funds in exchange for securities.
• OMO Sale
  • RBI sells government securities to banks or market participants.
  • This absorbs excess liquidity from the system, helping control inflationary pressures.

Through these operations, the RBI influences money supply, interest rates, and overall financial stability.

Government Securities (G-Secs)

Government Securities (G-Secs) are tradable financial instruments issued by the government to borrow money from the market.

Types of Government Securities:

• Treasury Bills (T-Bills)
  • Short-term instruments with maturity less than one year.
  • Issued only by the Central Government.
• Government Bonds or Dated Securities
  • Long-term instruments with maturity one year or more.
  • Issued by the Central Government.
• State Development Loans (SDLs)
  • Bonds issued by State Governments to finance their expenditure.

Because these securities are backed by the sovereign, they carry virtually no default risk and are therefore called risk-free or gilt-edged instruments.

Reasons for the Recent OMO Purchase

The RBI’s decision to purchase ?50,000 crore worth of G-Secs was aimed at:

• Injecting liquidity into the banking system.
• Stabilising financial markets during periods of tight liquidity.
• Easing pressure on the rupee by improving domestic liquidity conditions.
• Supporting smooth functioning of the government securities market.

As one of the largest players in the global diamond value chain, India’s leadership in the Kimberley Process can enhance transparency, improve traceability, and reinforce responsible diamond trade.

Conflict Diamonds: Meaning and Background

• Conflict diamonds, also known as blood diamonds, refer to rough diamonds mined in war zones and sold by rebel groups or their allies to finance armed conflicts against legitimate governments.
• The term gained global attention in the 1990s, when diamonds were found to be funding violent conflicts in several African countries such as Angola, Sierra Leone, Rwanda, and Liberia.
• These diamonds often entered global markets through informal and illegal trade networks, making their origin difficult to trace and raising concerns about ethical sourcing in the international diamond trade.

Kimberley Process Certification Scheme (KPCS)

The Kimberley Process, established in 2003, is a multilateral and voluntary certification mechanism designed to prevent conflict diamonds from entering the legitimate global diamond market.

Key features include:

1. Certification System – Every shipment of rough diamonds traded between participating countries must carry a Kimberley Process Certificate, confirming that the diamonds are conflict-free.
2. Trade Restrictions – Participating countries are allowed to trade rough diamonds only with other members of the Kimberley Process.
3. Global Coverage – The Kimberley Process accounts for over 99% of global rough diamond trade, making it a crucial framework for responsible diamond governance.
4. Monitoring and Compliance – Members commit to implementing internal controls and reporting mechanisms to ensure transparency in diamond trade.

India’s Diamond Industry

India plays a central role in the global diamond value chain:

• Largest cutting and polishing hub in the world, especially in cities such as Surat.
• Major importer of rough diamonds for processing.
• Leading exporter of cut and polished diamonds, with exports valued at about $13.3 billion in 2024–25.
• Second-largest diamond consumer market after the United States.

The Gem and Jewellery Export Promotion Council (GJEPC) acts as the nodal agency for implementing Kimberley Process certification in India. It operates under the Department of Commerce, Ministry of Commerce and Industry and is responsible for issuing certificates for diamond exports and imports.

Recently, Denmark was certified by the World Health Organization as the first country in the European Union to eliminate mother-to-child transmission (MTCT) of both HIV and Syphilis. This achievement represents a major public health success and demonstrates the effectiveness of strong maternal healthcare systems, universal testing, and timely treatment interventions.

What is Mother-to-Child Transmission (MTCT)?

Mother-to-Child Transmission (MTCT), also known as vertical transmission, refers to the spread of certain infections from a pregnant woman to her baby during pregnancy, childbirth and breastfeeding.

Without timely intervention, infections such as HIV and syphilis can lead to serious consequences including:

• Infant HIV infection
• Congenital syphilis
• Stillbirths and neonatal deaths
• Severe lifelong health complications

Therefore, preventing MTCT is a major priority in global maternal and child health programmes.

WHO Criteria for Elimination of MTCT

The WHO defines elimination of mother-to-child transmission through strict epidemiological and health system indicators. A country must achieve:

• Transmission rates below 50 cases per 100,000 live births, and
• More than 95% coverage of testing and treatment among pregnant women

These benchmarks ensure that both detection and treatment systems are robust enough to prevent transmission to newborns.

Global Context of EMTCT

Denmark joins a growing group of countries validated by the WHO for eliminating MTCT or making significant progress toward this goal. More than 20 countries and territories worldwide have achieved or are nearing this milestone.

Examples include:

• Caribbean nations such as Anguilla and Antigua and Barbuda
• South American countries such as Brazil
• African countries such as Botswana
• Asian nations including Malaysia and Maldives

These achievements demonstrate that elimination is possible across different health systems when strong policies and universal maternal healthcare are implemented.

WHO’s Triple Elimination Strategy

To address maternal transmission of infectious diseases, WHO promotes a Triple Elimination Strategy targeting: HIV, Syphilis, and Hepatitis B

The strategy is built on four key pillars:

• Universal access to antenatal care
• Integrated testing for maternal infections
• Effective treatment and prevention protocols
• Strong health systems supported by community engagement and human-rights protections
