Kukrail Night Safari — Supreme Court Clears India's First Night Safari Project

The Supreme Court has granted approval to the Uttar Pradesh government's Rs 1,510-crore Kukrail Night Safari and Day Zoo project in Lucknow. The project, proposed inside the ecologically sensitive Kukrail Reserve Forest, will be India's first night safari and the world's fifth, after Singapore, Thailand, China, and Indonesia. The approval follows four years of regulatory and judicial scrutiny.

• Location and Extent: Notified in 1950, Kukrail Reserve Forest spans approximately 4,500 acres on the outskirts of Lucknow, Uttar Pradesh — the city's largest contiguous green cover.
• Etymology: Named after the Kukrail stream, a tributary of the Gomti River that flows through the forest.
• Ecological Functions: Serves as Lucknow's key urban green lung — aiding carbon sequestration, temperature regulation, groundwater recharge, air purification, and climate resilience.
• Biodiversity Value: Supports birds, reptiles (including gharials), butterflies, and small mammals; contributes to the ecological health of the Kukrail stream.
• Kukrail Gharial Rehabilitation Centre (KGRC): Established in 1975, the KGRC is India's first gharial conservation centre. Over five decades, it has emerged as one of the world's most successful reptile breeding facilities, releasing gharials into rivers across India. It houses research laboratories, veterinary facilities, and rescue enclosures for gharials and turtles.

• Scientific Name: Gavialis gangeticus — a critically endangered crocodilian native to the Indian subcontinent.
• IUCN Status: Critically Endangered; one of the rarest reptiles on earth.
• Habitat: Restricted primarily to deep, fast-flowing rivers, especially the Chambal, Gandak, and Girwa rivers.
• Conservation Significance: The gharial is an indicator species for river health and a flagship of India's reptile conservation programme.

• Central Zoo Authority (CZA): A statutory body under the Ministry of Environment, Forest and Climate Change (MoEFCC) responsible for oversight, recognition, and regulation of zoos in India under the Wild Life (Protection) Act, 1972.
• Central Empowered Committee (CEC): A Supreme Court-appointed body that reviews projects involving forest land, wildlife habitat, and ecological concerns; it conducted inspections and recommended design modifications for the Kukrail project.
• Multiple Clearances Required: Projects inside reserve forests require State Wildlife Board approval, CZA recognition, and forest, wildlife, and environmental clearances under the Forest Conservation Act and Environment (Protection) Act.

The Rs 1,510-crore project will be developed across 855 acres within the reserve forest in two phases. Phase I covers the Night Safari and Eco-tourism Zone; Phase II encompasses the Day Zoo. The night safari will feature theme-based zones inspired by domestic and international wildlife landscapes, with naturalistic habitats incorporating grasslands, wetlands, rock formations, and native vegetation.

A key design feature is a specialised lighting system engineered to replicate the intensity and quality of natural moonlight. This allows visitors to observe nocturnal animals during their naturally active hours without causing stress or discomfort to the animals. Transport within the facility will be by battery-operated vehicles to minimise noise and emissions. The project master plan also includes conservation breeding facilities, wildlife interpretation centres, cafeterias, a 7D theatre, and an auditorium.

Proposed species habitats include Asiatic lions, Bengal tigers, leopards, hyenas, flying squirrels, and gharials. The facility is designed to accommodate approximately 4,000 visitors on weekdays and around 8,000 on weekends and public holidays.

The project was first announced by Chief Minister Yogi Adityanath in July 2022 and received cabinet approval the following month. However, its location within the Kukrail Reserve Forest — a protected urban green space — triggered multiple layers of regulatory review. State Wildlife Board and CZA approvals came in 2023. The Supreme Court-appointed CEC conducted site inspections, sought project design modifications, and the SC heard multiple rounds of arguments before clearing the project. The prolonged process reflects the legal and ecological weight given to forest and wildlife habitat diversion in India.

R. Vairamuthu Conferred the 60th Jnanpith Award

Tamil poet and lyricist R. Vairamuthu has been conferred the 60th Jnanpith Award for the year 2025. He is the third Tamil literary figure to receive this honour — the highest literary award in India — ending a 24-year gap since a Tamil writer last received the Jnanpith. His earlier recipients from Tamil literature were the late writers Akilan and Jayakanthan. Vairamuthu had previously won the Sahitya Akademi Award in 2003 for his work Kallikattu Ithikasam.

• Established: 1961, by the Bharatiya Jnanpith — a cultural organisation founded in 1944 by industrialist Sahu Shanti Prasad Jain and his wife Rama Jain.
• Nature: India's highest literary honour, often referred to as the "Nobel Prize of Indian literature." Recognises exceptional and outstanding contribution to Indian literature over a lifetime.
• First Award: Conferred in 1965 to G. Sankara Kurup for Malayalam literature.
• Scope of Works: From 1965 to 1981, the award was given for a specific book or work. Since 1982, it has recognised an author's overall lifetime contribution to Indian literature.
• Language Coverage: All 22 languages listed in the Eighth Schedule of the Constitution; English was included in 2013. No posthumous awards are given.
• Prize Components: A cash prize of Rs 11 lakh, a citation, and a bronze statuette of Vagdevi (Saraswati — the goddess of knowledge and speech). The award is customarily presented by the President of India.
• Selection: A high-level committee called the Pravara Parishad, comprising eminent scholars and litterateurs, evaluates nominations on the basis of creativity, vision, and impact on Indian literature.

• Renowned Tamil poet, lyricist, and literary figure; known primarily for his contributions to Tamil film poetry and classical literary forms.
• Recipient of the Sahitya Akademi Award (2003) for Kallikattu Ithikasam.
• Third Tamil literary figure to receive the Jnanpith Award, after a gap of 24 years.

• Awarded annually by the Sahitya Akademi (India's national academy of letters) for outstanding literary works in 24 recognised languages.
• The Sahitya Akademi is an autonomous body under the Ministry of Culture, established in 1954.
• Unlike the Jnanpith (lifetime achievement), the Sahitya Akademi Award is typically for a specific published work.

Tamil poet and lyricist R. Vairamuthu conferred the 60th Jnanpith Award for 2025 — third Tamil literary figure to receive India's highest literary honour.

Indian Grey Hornbill Breeds for Fourth Consecutive Year at Gir

More than six decades after the Indian Grey Hornbill disappeared from Gujarat's Gir forests, a peer-reviewed study published in the international journal Birds has documented four consecutive years of successful breeding following a structured reintroduction programme that began in 2021. The findings represent a significant milestone in India's wildlife restoration efforts and mark the species' confirmed re-establishment in the Gir ecosystem.

• Scientific Name: Ocyceros birostris
• IUCN Status: Least Concern
• Distribution: The most widely distributed hornbill species in India; range extends from Jammu to Kerala and from Rajasthan to West Bengal. Also found in parts of Pakistan, Nepal, and Bangladesh.
• Habitat Preference: Dry plains, foothills, open habitats; found in deciduous forests, orchards, thorny scrublands, gardens, and urban areas with old trees.
• Appearance: Ashy-grey body with long tail feathers bearing a white band; curved, ivory-coloured beak that is blackish at the base. A narrow protruding casque sits on the upper mandible — larger in males than females.
• Eye Features: Adults have red eyes with grey periorbital skin; juveniles have brown-orange eyes with reddish-orange skin.
• Ecological Role: An important seed disperser — contributes to natural forest regeneration across forest, agricultural, and urban landscapes.

• Location: Junagadh and Gir Somnath districts, Gujarat; the only wild habitat of the Asiatic Lion.
• Protected Area Status: Declared a Wildlife Sanctuary in 1965 and upgraded to include a National Park core in 1975. The improved protection following these declarations created favourable ecological conditions for the hornbill reintroduction.
• Ecological Context: The forest's gradual recovery under protection from the 1960s onwards made it a suitable candidate for restoring locally extinct species.

• Translocation refers to the deliberate capture and transfer of wildlife from one location to another for conservation purposes — either within a species' historic range (reintroduction) or to an unoccupied suitable habitat (introduction).
• Translocation is authorised under the Wildlife (Protection) Act, 1972, which empowers the Chief Wildlife Warden to permit such activities for scientific management.
• Success is measured through post-release monitoring of survival, settlement, habitat use, and — most critically — breeding behaviour, as reproduction indicates genuine population establishment.

Forty Indian Grey Hornbills were translocated from Gujarat's Aravalli forests to Gir in two phases: 28 birds during 2021–22, and a further 12 birds in 2023. To monitor their adaptation, 11 male hornbills were fitted with satellite transmitters, enabling scientists to track movement patterns, habitat use, settlement behaviour, and breeding activity. The study, published in Birds, documents successful breeding in each year from 2021 to 2024 — four consecutive breeding seasons — confirming that the reintroduced population has established itself in the Gir ecosystem.

The same news cycle also noted a separate conservation success: Gujarat recently recorded the survival of a second Great Indian Bustard chick beyond the critical 40-day threshold, hatched using the "jump-start" technique — a captive breeding and assisted hatching method being deployed to reverse the species' critical population decline.

Indian Grey Hornbill (Ocyceros birostris) — reintroduced to Gir in 2021; has bred successfully for four consecutive years (2021–2024).

Spotted Deer Translocation from Sasan Gir to Mandvi Forest

The Gujarat Forest Department has completed the translocation of 50 spotted deer (Chital) from the Sasan Gir Wildlife Division to the Mandvi Forest Range in Surat district. Conducted in three phases between May and June 2026, the initiative aims to strengthen the natural prey base for carnivores in South Gujarat, enhance local biodiversity, and reduce incidents of human-wildlife conflict by keeping predators within forest boundaries.

• Scientific Name: Axis axis; commonly known as Chital, Cheetal, or Axis Deer.
• Distribution: Native to the Indian subcontinent — India, Nepal, Bhutan, Bangladesh, and Sri Lanka. Introduced to the Andaman Islands, where it has become an invasive alien species.
• Habitat: Deciduous forests, open grasslands, and riverine habitats; commonly found along forest fringes where forest meets agricultural land.
• Physical Features: Golden-brown coat with white spots (spots are retained throughout life, unlike in most deer). Only males bear antlers — three-pronged, shed and regrown annually.
• Diet: Herbivorous; feeds on grasses, young shoots, leaves, and fallen fruit — a grazer and browser.
• Ecological Role: Forms a documented symbiotic association with Hanuman Langur monkeys (langurs drop fruit; deer eat them; langurs alert deer to predators). Serves as a key prey species for tigers, leopards, Asiatic lions, and Indian wolves — essential for maintaining top predator populations.
• Conservation Status: IUCN Red List — Least Concern (LC); protected under Schedule II of the Wildlife (Protection) Act, 1972.
• Threats: Habitat loss and fragmentation, poaching, and competition with livestock for grazing resources.

• HWC occurs when wildlife and human populations compete for the same resources — food, land, water — leading to crop damage, livestock predation, and occasionally attacks on humans.
• A depleted prey base is one of the primary drivers of large carnivore movement into human-dominated landscapes; predators venture outside forests when prey density within forests is insufficient to meet nutritional needs.
• Strengthening the herbivore base within forests is therefore a science-based, preventive approach to HWC mitigation — a demand-side management strategy for predators.

• Under the Wildlife (Protection) Act, 1972, the Chief Wildlife Warden of a state is empowered to permit the capture or translocation of wild animals for purposes of scientific management and conservation.
• Translocation operations require detailed habitat assessments of the receiving site to verify carrying capacity — food availability, water sources, cover, and absence of disease vectors.

The 50 deer were translocated in three batches: 21 on 23 May, 16 on 18 June, and 13 on 24 June 2026. Prior to the operation, the Gujarat Forest Department conducted detailed habitat assessments of the Mandvi Forest Range to confirm it could sustain the released population. Ten permanent water points were developed across the release area to ensure year-round drinking water availability — a critical factor for deer survival and settlement.

Post-release monitoring is being conducted through dedicated forest guards and trained trackers carrying out continuous field observation, supplemented by strategically placed camera traps to assess movement, habitat use, health status, and survival rates of the translocated animals.

Polluted River Stretches Decline from 351 to 296

The Union government informed the Rajya Sabha that the number of polluted river stretches across India has declined from 351 in 2018 to 296 in 2025, based on Biochemical Oxygen Demand (BOD) — a standard indicator of organic pollution in water bodies. The data comes from the latest report of the Central Pollution Control Board (CPCB). The interim figure in 2022 stood at 311, indicating a sustained but gradual improvement.

• Biochemical Oxygen Demand (BOD): Measures the amount of dissolved oxygen consumed by biological processes (mainly microbial decomposition of organic matter) in a given water sample over a set period — typically 5 days at 20°C. A high BOD indicates high organic pollution and low dissolved oxygen, harming aquatic life. It is the primary metric used by CPCB to classify polluted river stretches.
• Dissolved Oxygen (DO): The amount of oxygen dissolved in water. High DO is essential for fish and other aquatic organisms; low DO (often caused by high BOD) leads to hypoxic or dead zones.
• pH: Measures the acidity or alkalinity of water; extreme pH values (too acidic or alkaline) indicate industrial pollution and are harmful to aquatic life.
• Faecal Coliform (FC): Indicates contamination by human or animal sewage; a public health parameter for drinking water and bathing water quality.
• Heavy Metals: No specific standards for rivers have been prescribed as yet, though CPCB monitors parameters including pH, BOD, DO, and FC to assess overall river pollution levels.

• Central Pollution Control Board (CPCB): A statutory authority under the Ministry of Environment, Forest and Climate Change; responsible for monitoring water quality through the National Water Quality Monitoring Programme (NWQMP), which operates a network of 2,265 monitoring stations across the country in association with State Pollution Control Boards (SPCBs) and Pollution Control Committees (PCCs).
• CPCB Laboratories: One Central Water Laboratory in Delhi; eight regional laboratories for water quality analysis.
• State Pollution Control Boards (SPCBs): Maintain their own laboratories accredited either by the National Accreditation Board for Testing and Calibration Laboratories (NABL) or under the Environment (Protection) Act.

• Discharge of untreated or partially treated sewage from urban settlements and towns.
• Industrial effluents — especially from chemical, textile, tannery, and pharmaceutical industries.
• Inadequate dilution due to reduced river flows (abstraction for irrigation, reduced monsoon flows).
• Dumping of solid waste on riverbanks.
• Agricultural runoff carrying pesticides, fertilisers, and sediment.
• Geogenic effects — natural leaching of minerals from rock formations.
• Non-point sources of pollution (diffuse sources not traceable to a single discharge point).

The reduction of polluted stretches from 351 to 296 over seven years reflects incremental progress, but the pace signals that river restoration remains a long-term challenge. The persistence of 296 polluted stretches underscores structural deficits in sewage treatment infrastructure — India's urban sewage treatment capacity continues to lag significantly behind the volume of wastewater generated. The reliance on BOD as the primary classification metric, combined with the absence of prescribed heavy metal standards for rivers, also points to gaps in the comprehensiveness of river monitoring frameworks.

The National Water Quality Monitoring Programme's 2,265 stations, while extensive, must contend with the seasonal variability of river flows — pollution levels in rivers fluctuate significantly between lean-flow (non-monsoon) and high-flow (monsoon) seasons, complicating consistent assessment.

Why Inflation Is Rising in India — A Structural Perspective

India's Wholesale Price Index (WPI) inflation rose sharply to approximately 10% in June (reference period in article), driven primarily by fuel and power prices and manufactured goods — not by demand overheating. The spike follows a prolonged period of low or near-zero WPI inflation. The analytical piece argues that this inflation is structural in origin, not demand-pull, and calls for targeted fiscal policy responses including countercyclical indirect tax adjustments on fuel.

Magnetic Levitation: How Maglev Trains Work

Maglev (magnetic levitation) technology is receiving renewed global attention as a next-generation transport solution. With speeds exceeding 400 km/hr and a smooth, near-frictionless ride, maglev trains eliminate the mechanical limitations of conventional rail. Understanding the underlying physics and engineering trade-offs of maglev is increasingly relevant for UPSC aspirants, particularly in the context of India's infrastructure development ambitions and high-speed rail planning.

Nature has four fundamental forces: the two nuclear forces (strong and weak), the electromagnetic force, and gravity. Although gravity governs large-scale motion, it is far weaker than the electromagnetic force — approximately 10³⁹ times weaker. This enormous difference is what allows a small refrigerator magnet to hold against Earth's gravitational pull, and it is what makes levitating a 150–500 tonne train physically feasible.

By generating sufficiently powerful electromagnetic forces — using either conventional electromagnets or superconducting magnets — engineers can counteract gravity and lift a train off its guideway entirely, eliminating contact and, with it, rolling friction.

The walls of the maglev guideway are lined with electrical coils carrying alternating current (AC). This AC creates a continuously shifting magnetic field along the track — the poles (north and south) shift direction along the guideway at a controlled frequency. The magnets on the train are attracted to the opposite pole ahead and simultaneously repelled by the like pole behind, creating a net forward force. The train is thus pulled from the front and pushed from the back simultaneously. To increase speed, engineers simply raise the frequency of the alternating current.

The same linear motor principle governs braking: reversing the current direction switches the attracting and repelling poles, decelerating the train. Regenerative braking can capture the energy released during deceleration and feed it back into the electrical grid. Side-mounted magnets keep the train laterally centred within the guideway. Emergency friction brakes (auxiliary wheels or braking pads between guideway and train body) provide backup stopping capability.

• Dedicated Infrastructure: Maglev systems cannot share guideways or stations with conventional rail; the guideway must be purpose-built with embedded magnets, coils, and precision engineering — making retrofitting impossible.
• Construction Cost: The Shanghai Maglev, completed in 2004, cost Rs 580–720 crore per kilometre (inflation-adjusted) — excluding terrain preparation and ongoing operational/maintenance costs.
• Aerodynamic Drag: At speeds above 300 km/hr, aerodynamic resistance (air drag) replaces rolling friction as the primary resistance. Maglev trains require streamlined, aerodynamic designs — including a distinctive beak-shaped front section — to manage this. Such design adds to cost.
• Demand Threshold: The economics of maglev require very high and consistent passenger demand to justify capital and operating expenditure. Low ridership makes maglev economically unviable.

• Industrial Turbines and Compressors: High-speed rotating shafts are suspended in magnetic fields instead of conventional mechanical bearings, reducing friction and wear, and enabling higher rotational speeds.
• Aircraft Carrier Catapults: Modern aircraft carriers use linear motor technology (the same principle that propels maglev trains) to electromagnetically accelerate aircraft along launch runways — replacing older steam-powered catapults.
• Semiconductor Manufacturing and Factory Automation: Maglev-derived systems enable rapid, precise, vibration-free motion for semiconductor fabrication, food and pharmaceutical packaging, CNC machining, inspection imaging, and DNA sequencing.
• Scientific Levitation: Diamagnetism — a very weak magnetic property exhibited by all materials — can be exploited to levitate objects. British physicists Andre Geim and Michael Berry used a 10-tesla magnet to levitate a living frog in 1997 by calculating the field strength needed to cancel Earth's gravitational pull on the animal. This work earned them the Ig Nobel Prize in 2000. Notably, Andre Geim later also won the Nobel Prize in Physics (2010) for his work on graphene — making him the only scientist to have won both an Ig Nobel and a Nobel Prize.

A maglev train floats above its guideway using electromagnetic suspension — no wheel contact, no rolling friction, speeds exceeding 400 km/hr.

India Approves First Dengue Vaccine — QDENGA

Dr. Rajeev Singh Raghuvanshi, Drug Controller General of India (DCGI), has granted market authorisation to Takeda Biopharma's QDENGA (TAK-003), making it the first dengue vaccine to receive regulatory approval in India. The vaccine is approved for individuals aged 4 to 60 years for the prevention of dengue, irrespective of prior dengue infection history, and does not require pre-vaccination screening. India accounts for approximately one-third of the global dengue burden.

• Causative Agent: Dengue virus — a member of the Flaviviridae family; transmitted by the bite of infected Aedes aegypti and Aedes albopictus mosquitoes.
• Serotypes: Four distinct serotypes — DENV-1, DENV-2, DENV-3, DENV-4. Infection with one serotype confers lifelong immunity to that type but only temporary cross-protection against others. A subsequent infection with a different serotype carries higher risk of severe dengue (dengue haemorrhagic fever / dengue shock syndrome).
• Epidemiology in India: Reported dengue cases have increased nearly 11-fold over the past two decades. India bears approximately one-third of the global dengue burden; modelling studies suggest actual infections are substantially higher than officially reported cases.
• Seasonality: Dengue peaks during and after the monsoon season (July–October) when stagnant water provides breeding grounds for Aedes mosquitoes.

• DCGI (Drug Controller General of India): Head of the Central Drugs Standard Control Organisation (CDSCO); responsible for approval of new drugs, vaccines, and medical devices in India. Current incumbent: Dr. Rajeev Singh Raghuvanshi. Operates under the Ministry of Health and Family Welfare.
• CDSCO: India's national drug regulatory authority; functions under the Drugs and Cosmetics Act, 1940. Responsible for approval of clinical trials, new drug applications, and post-marketing surveillance (pharmacovigilance).
• New Drug Approval Pathway: Requires Phase I, II, and III clinical trials demonstrating safety, immunogenicity, and efficacy; a local Phase III trial (India-specific) is often required for domestic approval.

• Live-Attenuated Vaccine: Contains a weakened (attenuated) form of the live pathogen. The weakened virus can replicate in the body but does not cause disease in immunocompetent individuals; it stimulates a robust immune response including both antibody and cell-mediated immunity. Examples: MMR (measles-mumps-rubella), oral polio vaccine (OPV), varicella (chickenpox) vaccine.
• Tetravalent: A vaccine designed to provide protection against all four dengue serotypes (DENV-1 through DENV-4) simultaneously — critical because natural infection with multiple serotypes is common and each serotype can cause disease.
• Two-Dose Regimen: QDENGA is administered as two doses, given three months apart; does not require prior dengue serostatus testing before administration (unlike the earlier CYD-TDV/Dengvaxia vaccine, which required pre-vaccination screening for prior dengue exposure).

QDENGA's approval in India is underpinned by Takeda's global clinical development programme comprising 19 Phase I, II, and III trials involving over 28,000 participants across dengue-endemic and non-endemic regions. The pivotal Phase III trial enrolled more than 20,000 participants across eight dengue-endemic countries.

Security vs Ecology: BSF Considers Fencing in the Sundarbans

The Border Security Force (BSF) is conducting a feasibility study for installing physical fences along a 90-km stretch of the Sundarbans mangroves on the Indo-Bangladesh border. The government has separately sanctioned the construction of flood-light illuminated non-physical barriers in the area. The proposal has sparked debate among ecologists and security experts about the potential impact on the region's biodiversity, tidal hydrology, and local communities — set against the legitimate need to secure a porous and difficult-to-monitor border zone.

• Location: Spread across the delta of the Ganga, Brahmaputra, and Meghna rivers; shared between India (West Bengal) and Bangladesh. The Indian Sundarbans cover approximately 9,630 sq km.
• UNESCO World Heritage Site: The Sundarbans National Park is a UNESCO World Heritage Site (1987) and a Ramsar Wetland of International Importance.
• Biosphere Reserve: Declared a Biosphere Reserve under UNESCO's Man and Biosphere Programme.
• Ecosystem Type: The world's largest mangrove forest. Characterised by tidal creeks, brackish water, and a highly dynamic, fluid landscape shaped by tidal action — making fixed infrastructure inherently challenging to install and maintain.
• Biodiversity: Home to the Bengal Tiger (a strong swimmer, crosses rivers and tidal channels regularly), saltwater crocodiles, Irrawaddy dolphins, spotted deer, wild boar, and an exceptionally rich avifauna. The species here are adapted to a semi-aquatic, tidal lifestyle — river and sandbank crossings are routine, not exceptional, animal behaviour.
• Ichamati River: The proposed fencing site is on the banks of the Ichamati river in the northern Sundarbans — identified as lying partly within or adjacent to the Sundarbans Wildlife Sanctuary.
• Local Communities: Dense populations of fisherfolk, honey collectors (Mawalis), and agricultural communities live along the forest fringes, with significant land use conflicts and historical displacement concerns.

• BSF (Border Security Force): India's primary border guarding force; responsible for securing the Indo-Bangladesh international border — one of the longest land borders in the world at approximately 4,096 km.
• Challenge in Sundarbans: The tidal, mangrove terrain makes conventional border infrastructure (fencing, roads, patrol tracks) technically difficult and ecologically disruptive. Thick mangroves, creeks, and swamps restrict physical access for both border patrol and construction operations.
• Earlier Proposal: The BSF had previously explored the release of snakes and crocodiles into border rivers as deterrents — a proposal that itself generated ecological controversy.

Arguments for fencing (or regulated physical infrastructure): The Sundarbans is a porous border zone, and advocates for regulated infrastructure argue that illegal cross-border movement — including illegal fishing and construction within non-protected areas — has already caused significant ecological damage to unprotected mangrove zones. Dr. Krishna Ray (Associate Professor, Botany, West Bengal State University) notes that fencing in non-protected areas along the Bangladesh border need not harm the ecosystem significantly, provided the BSF exercises care to protect shoreline mangroves and wildlife during construction. Better border regulation, in this view, could reduce the illegal activities currently degrading the ecosystem.

Arguments against fencing: Dr. Megnaa Mehtta (Assistant Professor, Social Anthropology, University College London) argues that the Ichamati river is a natural corridor used routinely by tigers, deer, wild boar, and crocodiles — restricting it would disrupt normal wildlife movement. She characterises the project as a resource misallocation in an area that needs other fundamental infrastructure improvements more urgently. Decades of research, she notes, do not identify the Sundarbans as a primary route for serious cross-border infiltration. She also raises concerns about historical failures to compensate communities displaced by earlier infrastructure projects such as embankments.

Right to Protest — Constitutional Framework and Legal Restrictions

A large planned protest march to Parliament in New Delhi led to police action — including the use of prohibitory orders under Section 163 of the Bharatiya Nagarik Suraksha Sanhita (BNSS) — reigniting debate about the legal boundaries of the right to protest in India. Section 163 of the BNSS is the successor provision to Section 144 of the Code of Criminal Procedure (CrPC), which has been repeatedly examined by the Supreme Court for its constitutional validity and limits.

• Article 19(1)(a): Guarantees the freedom of speech and expression to all citizens.
• Article 19(1)(b): Guarantees the right to assemble peaceably and without arms.
• Not Absolute — Reasonable Restrictions: Articles 19(2) and 19(3) permit the State to impose reasonable restrictions on these rights in the interests of: sovereignty and integrity of India; security of the State; friendly relations with foreign States; public order; decency or morality; and other specified grounds.
• Key Distinction: The Constitution permits regulation of protests (where, when, how), but not their complete prohibition. Regulation is constitutionally valid; blanket prohibition is not.

• Nature: An emergency executive power — empowers an Executive Magistrate to issue written directions where "immediate prevention or speedy remedy" is considered necessary to prevent obstruction, danger to human life or public tranquillity, or the possibility of a riot or affray.
• Duration: Orders under Section 163 ordinarily remain in force for not more than two months, unless extended by law.
• Scope of Use in Practice: Empirical research (Bhandari, Sekhri, Maheshwari, and Aggarwal, 2023) examining approximately 5,400 Section 144 orders in Delhi (Jan 2021–2022) found that only about 1.5% related to prohibited unlawful assemblies; five of Delhi's 18 police districts issued no assembly-related orders at all. The study characterised the provision as having become a tool of routine administration — with orders mechanically re-issued at the end of every two-month statutory period, a "city-wide mechanical process."
• India's International Position: At the UN Human Rights Council (Geneva, 2021), India's representative affirmed that peaceful assembly is a constitutional right, while noting the government's obligation to balance it against public order and the right to life.

• Jantar Mantar, New Delhi: The Supreme Court's 2018 judgment reaffirmed Jantar Mantar Road as Delhi's designated protest site.
• Azad Maidan, Mumbai: Designated protest venue in Mumbai.
• SC-Directed Regulatory Guidelines (2018): Include — limiting number of participants, maintaining minimum distances from Parliament, the Supreme Court, and other sensitive locations; prescribing time limits; prohibiting weapons (firearms, lathis, swords).

The legal framework governing protests in India reflects a constitutional balance: robust protection for the right to assemble and speak, subject to reasonable and proportionate restrictions. The Supreme Court's consistent jurisprudence reinforces that executive powers like Section 163 BNSS are emergency tools — not instruments of routine governance or permanent prohibition. The empirical evidence from Delhi (2021–22) documenting the mechanical, cyclostyled re-issuance of Section 144 orders points to a structural gap between the provision's emergency design and its administrative reality.

For aspirants, the key constitutional distinction to internalise is: regulation = permissible; prohibition = unconstitutional. The State retains broad regulatory authority over where, when, and how citizens protest, but it cannot use that authority to eliminate the right to protest altogether.
