‘Master of Roster’ – Supreme Court vs. High Court, Judicial Authority, and Limits of Intervention

The Supreme Court’s recent reprimand of an Allahabad High Court judge for issuing an “absurd” judicial order has reignited a long-standing constitutional debate concerning the apex court’s authority to intervene in the internal functioning of High Courts. At the core of this issue lies the exclusive administrative power of the Chief Justice of a State High Court, commonly referred to as the ‘Master of the Roster.’ The controversy raises important questions surrounding judicial independence, the integrity of judicial institutions, and the scope of the Supreme Court’s powers under Articles 141 and 142 of the Constitution.

Background to the Controversy

The immediate trigger for this legal and constitutional discussion was the Supreme Court’s directive, issued by a Bench comprising Justices J.B. Pardiwala and R. Mahadevan, concerning Justice Prashant Kumar of the Allahabad High Court. The apex court ordered that Justice Kumar be assigned only in conjunction with a senior judge and be divested of any criminal roster responsibilities until his retirement, citing concerns over an erroneous judicial order he had passed.

This directive prompted a sharp reaction from members of the Allahabad High Court Bar and Chief Justice Arun Bhansali, who viewed the move as an encroachment upon the Chief Justice’s administrative prerogatives. The objection centred around the belief that the Supreme Court had effectively overridden the High Court Chief Justice’s powers as the ‘Master of the Roster.’

In response, Chief Justice of India B.R. Gavai communicated with the Supreme Court Bench, leading to a modification of the order. The revised direction clarified that the court’s intention was not to interfere with or diminish the Chief Justice’s authority in administrative matters.

Core Constitutional and Judicial Principles in Focus

At the heart of the matter lies the ‘Master of the Roster’ principle, which accords exclusive authority to a Chief Justice—whether of the Supreme Court or a High Court—to allocate judicial work, constitute benches, and assign matters. This principle has been firmly established through several landmark judgments.

In State of Rajasthan vs. Prakash Chand (1998), the Supreme Court affirmed that only the Chief Justice has the authority to decide which judge hears which case. Earlier, in State of Rajasthan vs. Devi Dayal (1959), the Court ruled that the High Court Chief Justice holds the discretion to determine whether matters should be heard by a single judge or a division bench. In the Madras High Court case of Mayavaram Financial Corporation (1991), it was further confirmed that the Chief Justice inherently holds the power to allocate judicial business within the court.

The hierarchical position of the Supreme Court is constitutionally reinforced under Article 141, which mandates that the law declared by the Supreme Court is binding on all courts in India. Article 142 grants the Supreme Court the power to issue any decree or order necessary to ensure “complete justice” in any matter, even if such actions lie beyond the conventional procedural framework.

In Tirupati Balaji Developers vs. State of Bihar (2004), the Supreme Court analogized its role as the “elder brother” in judicial administration but clarified that it does not possess supervisory powers over High Courts. The Indian judicial structure, while integrated, respects the constitutional independence of each court, including the High Courts.

Tensions Between Judicial Independence and Oversight

This episode brings to light the delicate balance between preserving the autonomy of High Courts and enabling institutional oversight. While the independence of the judiciary is a constitutional cornerstone, the integrated nature of the judicial system allows, in exceptional circumstances, for intervention by the Supreme Court—particularly when such actions are aimed at upholding the rule of law.

The present case underscores how such intervention, especially in internal administrative matters like roster allocation, can be seen as either necessary oversight or overreach. The underlying concern is whether the Supreme Court’s actions amount to indirect supervision over High Court judges, a domain traditionally insulated from such external influence.

Key Issues That Arise

Central to this debate is the question of whether the Supreme Court can, or should, issue administrative directions to a High Court Chief Justice concerning judicial roster assignments. The case also raises broader concerns about maintaining judicial discipline without compromising High Court autonomy. The invocation of Article 142 in this context suggests that the Supreme Court viewed its directive as a preventive and corrective measure, intended to avoid repeated judicial errors rather than as punitive action.

Furthermore, this situation highlights the internal tension within the judiciary between the hierarchical nature of courts and the constitutionally enshrined separation of powers. The issue revolves around how to balance the Supreme Court’s role as the highest court of the land with the administrative independence of High Court Chief Justices.

In-House Mechanisms vs. Public Censure

Traditionally, concerns over a judge’s conduct or competence are addressed through formal constitutional procedures such as impeachment by Parliament, which is reserved for cases of serious misbehaviour or incapacity. For lesser issues, an in-house inquiry mechanism is the preferred route. However, in the present case, the Supreme Court opted for a public directive delivered in open court, bypassing confidential internal procedures.

Importantly, this action did not constitute a punitive measure or formal censure. Rather, it was framed as a corrective initiative—pairing Justice Kumar with a senior colleague and relieving him of criminal matters was intended to function as a form of mentoring, aimed at improving judicial outcomes without triggering formal disciplinary proceedings.

Proposed Path Forward

In light of this episode, there is a pressing need for clear and consistent guidelines that delineate the circumstances under which the Supreme Court may legitimately intervene in the administrative functions of High Courts. At the same time, strengthening the judiciary’s internal, non-public mechanisms for addressing concerns about judicial performance or conduct would prevent such matters from escalating into public controversies.

Moreover, structured mentorship and continuing judicial education should be institutionalised to help judges, particularly those handling sensitive matters, avoid repeated legal errors. This proactive approach would reduce the need for top-down intervention while preserving the integrity and independence of all tiers of the judiciary.

Conclusion

The ‘Master of the Roster’ doctrine is vital to ensuring judicial independence and orderly court administration. However, this principle cannot be interpreted as an absolute shield against all forms of intervention, especially when judicial errors rise to a level that threatens the rule of law. The Supreme Court’s extraordinary powers under Article 142 allow it to take corrective action in such rare cases, but such intervention must be carefully calibrated to respect the autonomy of the High Courts.

Ultimately, maintaining a judicious balance between institutional oversight and judicial independence is essential for upholding public trust in the judiciary, protecting constitutional values, and ensuring the sound administration of justice across the country.

How AI is Reshaping India’s IT Industry and Workforce

Tata Consultancy Services’ (TCS) recent announcement to freeze experienced hiring and potentially cut 12,000 jobs has triggered widespread concern across India’s $280 billion IT industry, which employs over 5.8 million professionals. This development reflects not just a hiring slowdown but a broader wave of transformation sweeping through the sector, signalling a pivotal moment in its evolution.

AI-Led Transformation Driving Industry Disruption

Rather than simply being a case of artificial intelligence “eliminating jobs,” the ongoing changes in India’s IT sector point to a deeper, structural transformation led by AI. Industry analysts suggest that AI is fundamentally altering how software development and IT services are conceived and delivered. Its ability to drastically increase efficiency is forcing companies to re-evaluate their operating models, human resource strategies, and even the definition of IT work itself. At the heart of this shift lies AI’s capability to streamline the entire software development lifecycle, from coding to maintenance, in ways previously unimaginable.

AI’s Expanding Role in Efficiency and Cost Optimisation

Cost-efficiency remains the key driver behind new business deals in the IT sector, and AI is becoming central to how companies demonstrate value. With the backing of investors, firms are turning to AI to enhance productivity and cut costs. Tools such as AI-assisted coding platforms, automated code generators, and smart debuggers are reported to improve productivity by over 30%. These efficiencies are particularly pronounced in testing and maintenance operations, where AI significantly minimises human error and accelerates the detection of bugs, leading to quicker, more accurate deployment of software products.

Shifting Work Structures and Employment Patterns

Globally, AI is embedding itself across organisations, with over $1 trillion projected to be spent on AI development in 2025. Technologies ranging from generative chatbots to complex automation systems are transforming customer service, streamlining decision-making, and reconfiguring internal hierarchies. As low-code platforms and intelligent tools allow smaller teams to deliver greater output, hiring patterns are also being reshaped. This mirrors trends observed in firms like Wells Fargo in the United States, where staff reductions over the years have been driven largely by improvements in operational efficiency rather than external pressures.

Emerging Opportunities for Indian IT in the AI Era

Despite fears of job losses, AI adoption by global companies is fraught with significant challenges—such as obsolete infrastructure, poor data hygiene, and disjointed systems—which create critical dependencies on external expertise. With regulatory frameworks like the European Union’s AI Act mandating responsible and compliant AI systems, Indian IT firms are well-positioned to provide valuable support. By offering services that clean, integrate, and secure data, modernise legacy systems, and ensure regulatory compliance, Indian companies are being cast not as casualties of AI disruption but as strategic partners enabling global adoption of AI at scale.

TCS’s Strategic Shift Signals a Broader Industry Trend

As India’s largest IT services provider, TCS—with a workforce of over 607,000—has become a barometer for industry trends. Its recent decisions send multiple signals: to investors, they reflect a disciplined approach to costs and responsiveness to market dynamics; to clients, a pledge to offer more streamlined, AI-driven solutions; and to employees, a clear indication of the urgent need for upskilling. Industry commentators highlight that the era of massive, code-writing teams maintaining legacy systems is nearing its end. Instead, the next phase of IT will favour lean, AI-native firms adept at solving complex, domain-specific problems in areas such as healthtech, defence technology, fintech, sustainability, and education—where small, agile teams can often outperform vast workforces.

Workforce Evolution and Skill Adaptation in the AI Landscape

AI is not poised to replace every role—particularly those requiring deep technical knowledge, creative thinking, or domain expertise. Specialised roles such as C++ developers, user interface designers, robotics engineers, and technical architects remain in high demand. However, experts recommend that software professionals gradually transition into roles that complement AI, focusing on supervisory functions and collaborative responsibilities that involve ethics, security, and strategic domain knowledge. The shift at TCS, they argue, should be interpreted not as a setback, but as a wake-up call—prompting India’s vast tech workforce to adapt, re-skill, and position itself competitively for a future in which AI is central to every aspect of technology delivery.

From Manpower to Expertise: The Sector’s Strategic Pivot

Despite the turbulence, India’s IT sector continues to hold a dominant position globally, underpinned by a large, skilled workforce, proactive government initiatives for digitisation, and a vibrant startup ecosystem. Multinational corporations continue to choose India for their Global Capability Centres (GCCs), but the basis of that choice is changing. No longer is sheer headcount the defining metric; instead, specialisation, deep domain knowledge, and technological innovation—especially in AI—are taking centre stage.

This transition offers Indian IT firms an opportunity to reinvent their identity. Moving beyond their traditional reputation as outsourcing hubs, they can emerge as global leaders in intelligent automation, digital transformation, and next-generation technology services. As AI continues to reshape operational workflows, customer expectations, and business models, the industry’s longstanding pillars—people, process, and predictability—will be tested as never before. Meeting this challenge requires not just adaptation but strategic reinvention, ensuring India remains a powerhouse in the global digital economy.

Unpacking the Decline of Maoist Influence in India’s Red Corridor

The Maoist insurgency, once deeply entrenched across India’s Red Corridor, has seen a significant contraction and is now confined to just 18 districts. This reduction is the result of a complex interplay of factors—ranging from targeted development and sustained security efforts to leadership crises, ideological rigidity, internal fragmentation, and waning public support. While the decline marks a significant achievement in India''s internal security landscape, it also opens up new challenges in addressing the ideological and political undercurrents that once allowed the movement to thrive.

Understanding Left-Wing Extremism (LWE)

Left-Wing Extremism, or Naxalism, remains one of India’s most persistent internal security challenges. Rooted in socio-economic inequalities and propelled by Maoist ideology, LWE has long posed a threat to state authority by attacking security forces, disrupting infrastructure, and undermining democratic institutions. Originating from the Naxalbari uprising in West Bengal in 1967, the movement spread across vast swathes of central and eastern India—popularly termed the Red Corridor—encompassing states such as Chhattisgarh, Jharkhand, Odisha, Maharashtra, Andhra Pradesh, Telangana, and parts of others. Although Maoists have framed their struggle as a fight for the rights of the oppressed tribal populations, their tactics—such as armed violence, forced extortion, destruction of infrastructure, and child recruitment—have often contradicted their stated objectives.

Steady Decline in Maoist Activity

The Maoist threat, once regarded as India’s most formidable internal security crisis, has witnessed a dramatic decline in both geographical spread and intensity. From affecting nearly 180 districts at its peak in the late 2000s, the insurgency is now restricted to just 18. Between the decade spanning 2004–2014 and the subsequent period from 2014–2023, reported incidents of Maoist violence dropped by over 50%, while fatalities declined by nearly 70%. The year 2010 marked the peak of the insurgency, recording 1,936 incidents and 1,005 deaths. In contrast, by 2024, these figures had dropped to 374 incidents and 150 fatalities—signalling a consistent downward trajectory.

Contributing Factors to the Decline

A combination of developmental interventions and intensified security measures has played a decisive role in undermining the insurgency. Government schemes aimed at improving local infrastructure, livelihoods, and basic services have successfully challenged Maoist influence in many regions. These initiatives have been reinforced by targeted security operations, such as the high-impact 21-day counteroffensive in Narayanpur, which dealt a significant blow to the rebels'' operational capabilities.

Equally important has been the leadership crisis within the Maoist ranks. The resignation of long-time leader Muppala Lakshmana Rao, also known as Ganapathy, in 2018 marked a pivotal moment. His successor, Basava Raju, shifted the organisation''s strategy towards intensified militarism while neglecting political engagement—an approach that distanced the movement from its grassroots support. Raju''s death in 2025, reportedly the result of internal betrayal, has deepened the leadership vacuum, further weakening the organisation’s cohesion and strategy.

Internal divisions and organisational fragmentation have also accelerated the decline. Accounts from surrendered cadres reveal growing disillusionment and factionalism within the ranks. The CPI (Maoist)’s Politburo, once the movement''s strategic command, is now believed to be reduced to just four active members—highlighting a severe erosion in leadership capacity and decision-making power.

The loss of public support has been particularly damaging. In traditional strongholds like Dandakaranya, Maoist leaders prioritized armed conflict over community welfare, causing suffering among the very tribal populations they claimed to defend. As access to education, employment, and government welfare improved, younger members of these communities began rejecting violent rebellion in favour of integration into mainstream society.

This changing social outlook is evident in the testimonies of former Maoists such as Ginugu Narsimha Reddy, who now advocate for peaceful development. In areas like Gumla, Jharkhand, local initiatives such as fish farming have become symbols of alternative livelihoods, with over 150 families in Basia block alone adopting these sustainable occupations. These shifts represent a broader ideological decline of Maoism and the rise of economic and social aspirations rooted in peace.

Remaining Challenges and the Battle of Narratives

Despite these successes, some critics argue that the persistence of Naxalism, even in limited pockets, stems from a broader “protection ecosystem.” This includes political patronage that facilitated its early rise, state apathy that allowed it to embed itself in tribal regions, and intellectual or ideological advocacy that provided it with moral legitimacy. By framing the insurgency primarily as a struggle for tribal justice, this ecosystem helped obscure the violence, coercion, and extortion that defined much of Maoist strategy—enabling sympathisers to appear humanitarian while rationalising or even supporting insurgent violence.

As the central government sets an ambitious target to eliminate the Maoist insurgency entirely by 31 March 2026, the real challenge may lie not just in securing physical territory, but in dismantling this enabling narrative framework. Unless political actors, academic circles, and activist networks that supported or justified the movement are held accountable, the risk of ideological revival or romanticisation of Maoist goals will persist. In such a scenario, while security forces may continue to win operational victories on the ground, the larger war of ideas may remain unresolved.

Conclusion

The shrinking footprint of Maoist insurgency in India represents a major achievement in internal security, driven by strategic development initiatives, robust counterinsurgency, and a collapse of internal support structures. However, lasting peace will depend on addressing the deeper narratives and networks that once sustained the movement. As India moves toward its stated deadline for the complete eradication of Naxalism, the final phase of this struggle must involve both operational vigilance and intellectual clarity—ensuring that the insurgency’s ideological hold is dismantled as thoroughly as its military presence.

Revised Organ Transplant Allocation Policy Prioritises Women and Donor Families

The Union Government has introduced a major revision to India’s organ transplant allocation system, aimed at correcting gender imbalances and recognising the contribution of donor families. Through a 10-point advisory issued by the National Organ & Tissue Transplant Organisation (NOTTO), the new policy introduces measures to enhance transparency, fairness, and inclusivity within the transplant framework.

Introduction

The revised guidelines are designed to ensure that organ allocation is not solely based on clinical criteria but also reflects broader social considerations. Central to the update is the newly granted priority to women patients and to the immediate family members of deceased organ donors. This step is intended to address long-standing gender disparities and to incentivise more citizens to consider organ donation.

Existing Framework for Organ Allocation

Organ transplants in India are regulated by guidelines from NOTTO, operating under the Ministry of Health and Family Welfare. The system already employs a multi-factorial approach for allocation, based on:

·       Medical urgency: The severity of a patient’s condition.

·       Wait time: Duration on the national waiting list.

·       Compatibility: Blood group, organ size, and patient age.

·       Special conditions: Children and patients whose previous donors now require a transplant.

·       Geographic proximity: To ensure organ viability by reducing transit time.

The primary goal is to achieve equitable and medically optimal distribution of available organs.

New Priority Guidelines: Women and Donor Relatives

The recent changes incorporate “additional points in allocation criteria” for two specific groups:

1.     Women patients awaiting organ transplants.

2.     Immediate family members of deceased donors who had previously pledged or donated organs.

Rationale Behind the Reforms

The updated policy addresses two major systemic issues:

·       Gender Disparity: Historically, women have been underrepresented among organ recipients due to delayed medical attention, socio-cultural barriers, and lower healthcare access. The new criteria aim to rectify this imbalance by offering priority in organ allocation.

·       Donation Incentives: By recognising the altruistic contribution of donor families through priority access, the policy seeks to increase rates of deceased organ donation. India continues to face a severe shortage of organs, and this step may help address that gap.

Compliance and Data Management

NOTTO maintains a centralised digital registry for both organ donors and recipients. To maintain the integrity and transparency of the allocation system, hospitals must adhere to the following mandatory requirements:

·       All transplant centres are required to register patients through the NOTTO system.

·       Hospitals must submit comprehensive data for every transplant case.

·       Failure to comply may lead to legal action, underscoring the government’s commitment to regulatory enforcement.

Recent Organ Donation Milestones

India’s transplant ecosystem has seen significant progress in recent years, marked by both increased public awareness and institutional improvements:

·       2023: Launch of NOTTO’s Aadhaar-based online pledge portal, streamlining the process of organ donor registration.

·       2024: A landmark year, with over 3.3 lakh citizens pledging organ donations.

·       2024: A record 18,900 organ transplants were performed nationwide—up from fewer than 5,000 in 2013—signifying a nearly fourfold increase in a decade.

These milestones reflect a rising culture of donation and enhanced operational capacity within India’s healthcare system.

Strengthening Infrastructure and Capacity

To sustain and expand transplant services, the NOTTO advisory includes specific measures aimed at bolstering institutional capacity:

·       Establishing permanent positions for transplant coordinators in all organ transplant and retrieval hospitals.

·       Setting up organ retrieval centres at trauma hospitals and mandating their registration with NOTTO.

·       Encouraging medical colleges to develop retrieval facilities in a phased, structured manner.

·       Providing training to emergency responders and ambulance staff to help them identify potential deceased donors early—especially in trauma, road accidents, and stroke cases.

These steps aim to create a robust infrastructure capable of supporting the rising demand for transplants and improving overall system efficiency.

WHO Certifies Kenya for Elimination of Human African Trypanosomiasis

In a notable global health milestone, the World Health Organization (WHO) has certified Kenya as having successfully eliminated Human African Trypanosomiasis (HAT), commonly known as sleeping sickness, as a public health concern.

Understanding Human African Trypanosomiasis

Human African Trypanosomiasis is a parasitic disease caused by infection with protozoa transmitted through the bite of infected tsetse flies. It is endemic to sub-Saharan Africa and has long been a serious health concern in rural populations.

Symptoms and Progression

·       Initial symptoms include fever, headaches, and joint pain.

·       If left untreated, the disease can escalate to serious neurological complications, including disorientation, sleep disturbances, personality changes, and organ damage, especially to the brain.

·       Symptoms typically appear weeks or months after the initial infection, but the onset and progression depend on the specific parasite involved.

Two Distinct Forms of the Disease

1.     Trypanosoma brucei gambiense:

o   Prevalent in 24 countries across West and Central Africa.

o   Causes chronic infections; individuals may remain asymptomatic for years.

o   By the time symptoms appear, the central nervous system is often already affected.

o   Currently responsible for 92% of all reported HAT cases.

2.     Trypanosoma brucei rhodesiense:

o   Found in 13 countries in Eastern and Southern Africa.

o   Leads to acute infection, with rapid onset and disease progression.

o   Accounts for 8% of reported cases.

At-Risk Populations

The disease is most common among rural communities reliant on agriculture, fishing, livestock, or hunting, where contact with tsetse flies is more frequent.

Progress in Eradication

The WHO has officially recognised the elimination of the gambiense form of HAT as a public health problem in several African countries. These include: Togo (2020), Benin (2021), Ivory Coast (2021), Uganda (2022), Equatorial Guinea (2022), Ghana (2023), Chad (2024) and Guinea (2025)

With Kenya joining this list, it reflects growing success in vector control, surveillance, early diagnosis, and treatment efforts, as well as international collaboration in fighting neglected tropical diseases.

Breakthrough in Understanding Chiton Biology

In another significant scientific advancement, researchers have uncovered remarkable findings about chitons, a group of marine invertebrates. A recent study reveals that chitons possess teeth that surpass even stainless steel, zirconium oxide, and human enamel in hardness, marking a unique evolutionary adaptation in the animal kingdom.

Overview of Chitons

• Chitons are marine mollusks with a flattened, bilaterally symmetrical body structure.
• They belong to the phylum Mollusca, a group that includes other well-known marine organisms such as sea snails, slugs, and bivalves.
• Found exclusively in marine environments, chitons are globally distributed, with higher densities in warmer coastal regions.

Distinctive Features

• Chitons typically exhibit an oval shape and vary in colouration, appearing in grey, brown, red, green, and pink shades.
• Their dorsal side is protected by eight overlapping plates, which are either surrounded or covered by a tough girdle.
• For locomotion and adhesion, chitons rely on a broad, flat foot that allows them to creep along rocky surfaces and firmly attach to them.
• They are equipped with a radula—a specialised, file-like feeding structure—used to scrape algae and plant material from rocks.
• On each side of the foot lies a gill-bearing groove, enabling respiration.

Chitons are highly adaptable and flexible. They can tightly wedge themselves into rocky crevices or curl into a defensive ball if dislodged. Their adhesive strength is so formidable that they risk injury when forcibly removed from rock surfaces.

Most chitons are nocturnal and measure up to 5 cm (2 inches) in length. Depending on the species and environmental conditions, their life span ranges from a few years to as long as 20 years.

Discovery of Heptapleurum assamicum in Assam

Scientists have recently identified a new plant species, Heptapleurum assamicum, in the northeastern Indian state of Assam, specifically in the Dima Hasao and West Karbi Anglong districts. This lush, evergreen shrub contributes to the growing documentation of India’s rich botanical diversity.

Characteristics of Heptapleurum assamicum

·       This newly identified species belongs to the Araliaceae family, the same family that includes the widely cultivated ornamental “umbrella plant” (Heptapleurum arboricola).

·       Unlike its ornamental relative, H. assamicum exhibits distinctive morphological traits:

o   The leaflets are narrow and lance-shaped, not exceeding 1.2 cm in width.

o   The flowers are a vivid purple, differing markedly from the greenish-yellow hue of H. arboricola.

o   The inflorescence is compact, with up to 15 flowers per umbel.

o   When ripe, the fruit turns a deep reddish-purple and is dotted with orange-red glands, an uncommon feature within its genus.

·       The plant’s flowering period occurs from January to March, while fruiting follows by May.

Currently, the known population of Heptapleurum assamicum is extremely small and geographically restricted, rendering it potentially susceptible to environmental threats. Due to the limited data available, it has been provisionally classified as “Data Deficient” under IUCN criteria, pending further ecological assessment.

Mississippi River: Geographical Significance and Recent Incident

A recent helicopter crash into a barge on the Mississippi River near East Alton, Illinois, resulted in two fatalities, drawing renewed attention to this iconic American waterway.

About the Mississippi River

The Mississippi River holds the distinction of being the longest river in the United States and the second longest in North America. It originates from Lake Itasca in northern Minnesota and flows southward until it empties into the Gulf of Mexico.

·       The river spans more than 2,300 miles (approximately 3,700 kilometers) on its own.

·       When combined with its longest tributary, the Missouri River, the Mississippi-Missouri River system becomes the fourth longest river system in the world—following the Nile, Amazon, and Yangtze rivers.

·       The Mississippi River basin is vast, draining approximately 1,260,000 square miles, making it the largest drainage basin in North America by area.

Major Tributaries

The Mississippi River is fed by several major tributaries, which include: Missouri River, Ohio River, Arkansas River, Illinois River, Red River

Ecological Diversity of the Basin

The Mississippi River basin is home to a wide array of ecosystems, contributing to its environmental and ecological importance:

·       Wet forests predominantly featuring cypress trees

·       Freshwater and brackish marshes

·       Salt marshes closer to the Gulf coast

·       Sandy beaches and transitional wetlands

These ecosystems support numerous species of flora and fauna and play a critical role in sustaining biodiversity in North America.

Parthenium Eradication Initiative in Pobitora Wildlife Sanctuary

As part of the "Parthenium Free Pobitora" campaign, forest authorities in Assam’s Morigaon district undertook a three-day operation to clear 5.2 hectares of the Pobitora Wildlife Sanctuary of Parthenium hysterophorus, commonly referred to as Congress grass. This targeted effort is part of a broader ecological management strategy to eliminate invasive species that threaten local biodiversity.

About Parthenium hysterophorus

Parthenium hysterophorus, also known in India as carrot weed, white top, or Congress grass, is an annual, herbaceous, and erect plant belonging to the Asteraceae (Compositae) family. Despite its non-native origin, it has aggressively spread across India, becoming one of the country''s most problematic invasive weeds.

Origin and Spread

·       The plant is believed to have originated in Mexico, America, Trinidad, and Argentina.

·       Its first notable presence in India was recorded in Pune, Maharashtra, in 1955, after which it spread rapidly throughout the country.

·       Currently, approximately 35 million hectares of Indian land are invaded by Parthenium.

·       It primarily spreads via seeds, with each plant producing 5,000 to 25,000 seeds.

·       These seeds are extremely small and lightweight, facilitating easy dispersion by wind, water, or human activity.

Threats and Nuisance

Parthenium poses multiple threats to the environment, agriculture, and public health:

·       It is toxic and highly allergenic, responsible for severe medical conditions such as dermatitis, asthma, and nasal-bronchial diseases in humans.

·       It is equally dangerous to livestock, affecting grazing patterns and causing toxicity.

·       The weed causes blockages in public spaces, affecting pathways, parks, gardens, and residential areas, diminishing their aesthetic and functional value.

·       It encroaches on roadsides, railway tracks, vacant lands, wastelands, industrial sites, and open drainage systems.

·       Critically, it invades agricultural fields, orchards, and forest ecosystems, threatening native flora and reducing biodiversity.

·       Its local name, "gajar ghas", is derived from its visual resemblance to the carrot plant.

Ecological Importance of Pobitora Wildlife Sanctuary

Located in the eastern part of Guwahati, Assam, Pobitora Wildlife Sanctuary was established in 1998 and covers a total area of 48.81 square kilometres. It is composed of the Rajamayong Reserve Forest and the Pobitora Reserve Forest.

Floral Diversity

Approximately 72% of the sanctuary''s landscape is covered in wet savannah vegetation, including species such as: Arundo donax, Erianthus ravennae, Phragmites karka, Imperata cylindrica and Saccharum species

However, the sanctuary faces challenges from invasive aquatic plants, notably water hyacinth (Eichornia crassipes), which hampers aquatic biodiversity by forming thick mats on water surfaces, obstructing light penetration and oxygen circulation, especially detrimental to waterfowl.

Faunal Richness

Pobitora is globally recognized for its high density of Greater One-Horned Rhinoceros, making it a critical conservation zone for this vulnerable species.

Apart from rhinos, the sanctuary supports a diverse range of wildlife, including: Leopards, Wild boars, Barking deer and Wild buffalo.

Additionally, it serves as a habitat for over 2,000 migratory birds, enhancing its ecological value as a vital wetland ecosystem and birdwatching hotspot. Various reptilian species also thrive in this protected area.
