State Government, Constitutional Provisions, Structure, Functions

State Government

The State Government is the governing authority at the regional level in India, responsible for law and order, administration, and socio-economic development within a state. It functions under the framework of the Indian Constitution and ensures decentralised governance to meet local needs. 

State Governments implement policies, deliver public services, and act as a bridge between citizens and the Union Government. A detailed article on the structure, functions, challenges, and role of State Governments has been discussed below.

State Government Formation

The formation of a State Government takes place after elections to the State Legislative Assembly, reflecting the parliamentary system at the state level. The executive is drawn from the legislature and remains accountable to it.

  • State Assembly elections are conducted by the Election Commission of India.
  • The party or coalition securing a majority is invited to form the government.
  • The Governor appoints the leader of the majority party as the Chief Minister.
  • Other ministers are appointed by the Governor on the advice of the Chief Minister.
  • The Council of Ministers is collectively responsible to the Legislative Assembly.
  • A floor test may be conducted to prove majority support.

State Government Constitutional Provisions

The Structure of the State Government is broadly similar to that of the Union Government and is based on the principle of separation of powers. It consists of three organs: Executive, Legislature, and Judiciary, each performing distinct functions while maintaining checks and balances.

1. State Executive

The State Executive is responsible for the administration and implementation of laws and policies within the state. It consists of the Governor, Chief Minister, and the Council of Ministers, where real executive power lies with the elected government.

(a) Governor

  • The Governor is the constitutional head of the state, appointed by the President (Article 153).
  • Acts as the nominal executive, while functioning mainly on the aid and advice of the Council of Ministers (Article 163).
  • Appoints the Chief Minister, Council of Ministers, Advocate General, and members of the State Public Service Commission.
  • Possesses legislative, executive, and discretionary powers, including reserving bills for the President.

(b) Chief Minister

  • The Chief Minister is the real executive authority and head of the State Government.
  • Appointed by the Governor, usually the leader of the majority party in the Legislative Assembly.

(a) High Court

  • The highest judicial authority in the state (Article 214).
  • Exercises original, appellate, and writ jurisdiction.
  • Acts as the guardian of the Constitution at the state level.
  • Supervises subordinate courts and tribunals.

(b) Subordinate Courts

Centre-State Relations and Role of States

Centre–State Relations form a critical aspect of Indian federalism, ensuring coordination between the Union and state governments. States exercise autonomy over local matters while cooperating with the Centre in areas of shared responsibility to promote balanced national development.

  • States have exclusive powers over subjects in the State List.
  • Both Centre and States share responsibilities on Concurrent List subjects like education, forests, and criminal law.
  • Financial dependence exists through tax devolution, grants-in-aid, and centrally sponsored schemes.
  • Mechanisms like Inter-State Council and Finance Commission facilitate coordination and dispute resolution.
  • States act as partners in cooperative federalism, implementing national policies at the regional level.
  • Centre–State tensions may arise but are managed through constitutional provisions and legal frameworks.
  • States play a role in regional planning, local governance, and policy adaptation to local needs.

Role of State Government in Local Self Governance

State Governments play an important role in strengthening local self-governance by empowering Panchayati Raj Institutions (rural) and Municipal Bodies (urban).

  • Delegation of Powers: State Governments devolve authority, responsibilities, and funds to local bodies under the 73rd and 74th Constitutional Amendments.
  • Financial Support: Provision of grants-in-aid, tax-sharing, and budget allocations to ensure local bodies can function effectively.
  • Capacity Building: Training elected representatives and officials for efficient administration and planning at the grassroots level.

  • Monitoring & Evaluation: Assessing the performance of local institutions and ensuring accountability and transparency in governance.

Challenges Faced by State Governments in India

State Governments in India face multiple challenges that affect their ability to deliver effective governance and promote regional development. These challenges are financial, administrative, political, and environmental in nature, often limiting their autonomy and efficiency.

  • Fiscal Constraints: Dependence on Centre for funds and limited revenue sources.
  • Centre-State Tensions: Conflicts over legislative, administrative, and financial powers.
  • Administrative Inefficiency: Bureaucratic delays and lack of capacity in governance.
  • Regional Disparities: Unequal development between districts and urban–rural areas.
  • Infrastructure Deficits: Inadequate transport, health, and education facilities in some states.
  • Urbanisation and Population Pressure: Rapid growth strains resources and services.
  • Environmental Challenges: Climate change, natural disasters, and resource depletion impact planning and development.

Reforms Needed in State Governance

To strengthen State Governments and improve governance outcomes, comprehensive reforms are necessary. These reforms should focus on enhancing autonomy, accountability, efficiency, and coordination with the Centre, ensuring responsive and inclusive governance.

  • Financial Autonomy: Greater tax devolution and fiscal independence from the Centre.
  • Administrative Reforms: Streamlining bureaucracy, reducing delays, and improving service delivery.

Karewas, Types, Formation, Significance, Threats, Conservation

Karewas

What are Karewas?

Karewas are elevated flat-topped plateaus found mainly in the Kashmir Valley, lying above the present-day floodplains of the Jhelum River and its tributaries. They consist largely of lacustrine (lake-deposited) sediments such as clays, silts, sands, and gravels.

These landforms were formed during the Quaternary period when the Kashmir Valley was occupied by large freshwater lakes. Over time, tectonic uplift and river erosion drained these lakes, leaving behind flat terraces known as Karewas.

Types of Karewas

Karewas can be broadly classified based on their location, elevation, and composition. The major types include:

  1. Lower Karewas
  • Found closer to river floodplains.
  • Composed mainly of fine sediments like clay and silt.
  • Highly fertile and extensively used for agriculture.
  1. Higher Karewas
  • Located at higher elevations above the valley floor.
  • Contain coarser materials such as gravel and sand.
  • Less fertile but ideal for horticulture and saffron cultivation.
  1. Fluvio-lacustrine Karewas
  • Formed due to combined action of lakes and rivers.
  • Show layered deposits of lake sediments and river alluvium.

Formation of Karewas

The Formation of Karewas is closely linked to the geological evolution of the Kashmir Valley.

  • Tectonic Activity: Uplift of the Himalayas led to the formation of a closed basin in the Kashmir region.
  • Ancient Lake System: The basin was filled with large freshwater lakes, notably the Karewa Lake.
  • Sedimentation: Fine sediments like clay, silt, and sand settled at the lake bottom over thousands of years.
  • Drainage of Lakes: River capture and down-cutting by the Jhelum River drained the lakes.
  • Erosion and Terrace Formation: Differential erosion left behind flat-topped terraces, now known as Karewas.

Karewas Significance

  1. Agricultural Value - Karewas have well-drained lacustrine soils ideal for saffron cultivation and dryland crops like almonds, walnuts, and pulses, with low flood risk.
  2. Economic Importance - High-value saffron and horticulture from Karewas provide sustainable livelihoods, support agro-based industries, and boost the regional economy of Kashmir.
  3. Ecological Role - They act as groundwater recharge zones, support plateau-specific vegetation, and help maintain local micro-climatic balance.
  4. Geomorphological Significance - Karewas are classic lacustrine depositional landforms, offering evidence of ancient lakes, Himalayan uplift, and past climatic conditions.
  5. Hydrological Function - Elevated terraces regulate surface runoff, enhance rainwater percolation, and help reduce flooding in adjacent low-lying areas.
  6. Cultural-Historical Importance - Historically preferred for settlements due to flood safety and central to Kashmiri cultural identity through saffron cultivation.

Threat to Karewas

  • Unregulated Urbanisation - Rapid expansion of towns and cities in the Kashmir Valley has led to large-scale encroachment and conversion of Karewa land for housing and commercial use.
  • Brick Kilns and Clay Mining - Excessive extraction of Karewa clay for brick-making causes irreversible soil loss, land degradation, and destruction of ancient lacustrine deposits.
  • Infrastructure Development - Construction of roads, railways, and industrial projects fragments Karewas, disrupts natural drainage, and accelerates erosion.
  • Agricultural Mismanagement - Overuse of chemical fertilisers, poor irrigation practices, and monocropping (especially saffron) reduce soil fertility and long-term productivity.
  • Climate Change Impacts - Altered rainfall patterns, frequent droughts, and rising temperatures negatively affect soil moisture and saffron yield on Karewas.
  • Deforestation and Vegetation Loss - Removal of natural vegetation cover increases wind and water erosion, making Karewas more vulnerable to degradation.
  • Weak Regulation and Enforcement - Lack of strict land-use policies and poor enforcement allow illegal mining, construction, and land conversion to continue unchecked.

Conservation and Sustainable Management of Karewas

  • Grant strict legal protection to Karewas by regulating land-use change, construction, and mining through effective enforcement mechanisms.
  • Completely restrict brick kilns and clay mining to prevent irreversible soil and geomorphological damage.
  • Promote sustainable and low-input farming practices to conserve soil fertility and productivity.
  • Implement efficient water management measures such as rainwater harvesting and micro-irrigation.
  • Involve local communities and farmers in conservation through awareness and incentive-based programmes.
  • Use GIS and remote sensing for continuous monitoring of land degradation and encroachment.
  • Integrate Karewa protection with climate-resilient planning and sustainable development strategies.

Karewas FAQs

Q1: What are Karewas?

Ans: Karewas are flat-topped elevated plateaus of lacustrine origin found mainly in the Kashmir Valley.

Q2: Where are Karewas located in India?

Ans: They are primarily found in the Kashmir Valley, especially in Pampore, Budgam, and Baramulla regions.

Q3: How were Karewas formed?

Ans: Karewas were formed by deposition of sediments in ancient lakes, later shaped by tectonic uplift and river erosion.

Q4: Which crop is most closely associated with Karewas?

Ans: Saffron is the most important crop grown on Karewas.

Q5: What are the major threats to Karewas?

Ans: Urbanisation, brick kilns, clay mining, infrastructure development, and climate change.

105th Constitutional Amendment Act, Important Dates, Significance

105th Constitutional Amendment Act

The 105th Constitutional Amendment Act, 2021 officially titled the Constitution (One Hundred and Fifth Amendment) Act restored the authority of State governments to identify Socially and Educationally Backward Classes (SEBCs), including Other Backward Classes (OBCs). This amendment was introduced in response to a Supreme Court ruling in 2021, which interpreted the 102nd Amendment as having taken away this power from the States. To address the issue promptly, the amendment was passed by both Houses of Parliament and received Presidential assent on August 18, 2021.

105th Constitutional Amendment Act

The Constitution (One Hundred and Fifth Amendment) Act, 2021 reaffirmed the authority of state governments to identify and notify Socially and Educationally Backward Classes (SEBCs), which include communities such as Other Backward Classes (OBCs). This amendment clarified the state’s power to prepare and maintain their own list of SEBCs, following concerns raised after a Supreme Court judgment. It was enacted after receiving the assent of the President of India on August 18, 2021. As of September 28, 2023, the Indian Constitution has undergone a total of 106 amendments since it came into effect in 1950.

105 Constitutional Amendment Act

The 105th Constitutional Amendment Act, 2021 is the most recent amendment to the Indian Constitution. Its purpose is to restore the power of state governments to identify and list Other Backward Classes (OBCs) who are socially and educationally backward.

This amendment modifies clauses (1) and (2) of Article 342A and introduces a new clause (3). It also amends Articles 366(26C) and 338B. The key takeaway is that states retain the authority to maintain their own OBC lists.

The 102nd Amendment had created a Central List of OBCs controlled solely by the Centre, without affecting the state’s powers. However, confusion over its interpretation raised concerns that states might lose the right to identify backward communities.

It ensures that around 671 OBC communities can continue to access reservation benefits in state-run education and employment benefits they might have lost if the state lists were invalidated.

Also Check: 103rd Constitutional Amendment Act

Prime Reasons for Latest Amendment of the Indian Constitution (105th)

The 105th Constitutional Amendment Act was enacted to restore the authority of states and Union Territories to maintain their own lists of Other Backward Classes (OBCs). Under Articles 15(4), 15(5), and 16(4) of the Indian Constitution, states are empowered to identify and declare socially and educationally backward classes. In practice, both the Centre and individual states maintain separate OBC lists. The need for this amendment arose following the Supreme Court's judgment in the Maratha reservation case, which upheld the 102nd Constitutional Amendment Act. That amendment had introduced Articles 338B and 342A, placing the power to specify backward classes with the President, in consultation with Governors, thereby limiting the role of states. The 105th Amendment sought to clarify and reinstate the state’s legislative competence in this domain.

  • It establishes that the Central List of OBCs will only be applicable to the Central Government and its institutions.
  • The Amendment does not interfere with State Lists or limit the State’s authority to recognize or notify backward communities.
  • Nearly 671 OBC communities stood to lose reservation benefits in education and employment if the State List had been abolished. This Amendment safeguards their rights.
  • It reflects the government's commitment to social justice, equality, and inclusive development, particularly for historically marginalised communities.

105th Constitutional Amendment Impact

The 105th Constitutional Amendment Act brought notable changes by amending Clauses (1) and (2) of Article 342A and inserting a new Clause (3). It made corresponding amendments to Articles 366 and 338B. The primary objective of this Amendment was to restore the authority of state governments to identify and notify Socially and Educationally Backward Classes (SEBCs) for their respective states.

By modifying the above-mentioned provisions, the Amendment reinstated the power of states to maintain their own list of SEBCs, an authority that had been reduced following the Supreme Court’s interpretation in the Maratha reservation judgment. This legislative intervention aimed to strike a balance between the centralised framework of backward class identification and the federal structure of governance.

The debate over reservations both in support and opposition has been ongoing for decades. Despite several decades of independence, India continues to grapple with socio-economic disparities. The 105th Amendment marks another legislative effort towards achieving social justice and equal opportunity by enabling states to better address the specific needs of underrepresented communities within their jurisdictions.

Daily Editorial Analysis

Cutting off a Rural Lifeline and the Directive Principles

Context

  • The central government’s move to replace the Mahatma Gandhi Rural Employment Guarantee Act (MGNREGA) represents a fundamental attack on India’s constitutional vision of social and economic justice.
  • Passed using the government’s majority in the Lok Sabha, the proposed Bill alters the very nature of MGNREGA by dismantling its rights-based and democratic framework.
  • This is not a routine policy reform but a serious erosion of the Directive Principles of State Policy and a direct assault on the rural working poor, warranting scrutiny by the Standing Committee of Parliament.

Constitutional Foundations of the Right to Work

  • Article 41 of the Constitution directs the State to make effective provision for securing the right to work within its economic capacity.
  • During the Constituent Assembly debates, this provision emerged as a compromise between socialist members, who sought to make the right to work a fundamental right, and capitalist interests, who opposed such an obligation.
  • As a result, the right to work was placed among the Directive Principles, non-justiciable but central to economic democracy.
  • B.R. Ambedkar described the Directive Principles as instruments of instruction essential for economic democracy, while K.T. Shah dismissed them as pious wishes.
  • Decades of unemployment and exclusion under capitalist development have shown how fragile this constitutional promise remained until political circumstances forced a shift.

MGNREGA Act

  • The Act guaranteed 100 days of work per rural household, was universal, and open to all adults willing to perform manual labour.
  • Crucially, it was demand-driven, responding to actual need rather than fixed bureaucratic targets.
  • This structure gave MGNREGA deep democratic content. Households retained freedom to seek better employment while relying on MGNREGA as a fallback.
  • Equal wages for men and women, full central funding of wages, and meaningful roles for States and panchayats strengthened its inclusive and federal character.
  • It was among the first such laws in the capitalist world.

Concerns Surrounding the Proposed Viksit Bharat- G RAM G Bill 2025

  • Dismantling the Core Features of MGNREGA

    • The proposed Bill under the Modi government scraps these foundational principles.
    • The demand-driven mechanism is replaced by normative financial allocations fixed by the Centre, absolving it of legal responsibility once funds are exhausted.
    • At the same time, States are burdened with 40% of costs, despite ongoing fiscal stress and denial of their fair share of tax revenues.
    • The Bill introduces extreme centralisation, transferring control over project design, implementation, and audits to the Union government.
  • Undermining the Federal Structure

    • This undermines the federal structure of the Constitution and marginalises States and panchayats, which earlier had authority to design projects based on local needs.
    • A clear class bias is evident in the prohibition of work during peak agricultural seasons. With increased mechanisation, agricultural employment has shrunk sharply.
    • Evidence shows that workers opt for MGNREGA during peak seasons only when agricultural wages fall below MGNREGA rates or work is unavailable.
    • The ban weakens workers’ bargaining power, forcing them into exploitative conditions imposed by large landowners, disproportionately harming women.
  • Digital Exclusion and Symbolic Politics

    • The Bill legalises Aadhaar linkage and mandatory digital attendance for eligibility and wage payments, despite widespread evidence of exclusion due to poor connectivity and technical failures.
    • These measures transform a rights-based guarantee into a bureaucratic hurdle.
    • Renaming the scheme as the Viksit Bharat–G RAM G Bill 2025 reflects symbolic politics rather than substantive reform and risks provoking widespread resistance from those whose livelihoods are threatened.

Social Realities and Agrarian Distress

  • The harsh working conditions under MGNREGA highlight persistent rural distress.
  • Women often lift up to 3,000 kilograms of mud per day to meet productivity norms.
  • Their participation, over 50% in most States, signals not choice but the absence of better alternatives.
  • The social composition of workers underscores the law’s constitutional importance. Adivasis (18%) and Scheduled Castes (19%) are vastly overrepresented relative to their population share, together forming over two-thirds of the workforce.
  • Rolling back their rights constitutes an attack on constitutionally protected communities, worsened by their removal from advisory and grievance redress mechanisms in the draft law.

Starvation of Funds and Manufactured Failure

  • Since 2014, MGNREGA has been systematically underfunded, even as corporate tax concessions and write-offs have expanded.
  • Worker participation has risen to over 7.7 crore, yet expenditure has stagnated below 2% of GDP.
  • In 2024–25, nearly one crore workers were denied work, wage arrears ran into thousands of crores, and households received less than 50 days of work on average.
  • Promises of 125 days of work in the new Bill appear cynical and hollow.

Conclusion

  • MGNREGA remains an indispensable lifeline for India’s rural poor amid agrarian distress and unemployment.
  • The proposed Bill dismantles its rights-based, democratic, and federal foundations, bulldozing the Directive Principles of the Constitution and undermining the vision of economic democracy.
  • Strengthening, not weakening, the right to work is the true constitutional mandate, and the proposed replacement fails that test decisively.

Cutting off a Rural Lifeline and the Directive Principles FAQs 

Q1. What constitutional principle does MGNREGA seek to uphold?
Ans. MGNREGA seeks to uphold the constitutional principle of the right to work under Article 41 of the Directive Principles.

Q2. Why was the role of the Left crucial in the enactment of MGNREGA?
Ans. The Left was crucial because its parliamentary support enabled the adoption of a rights-based, demand-driven employment law.

Q3. How does the proposed Bill alter the nature of MGNREGA?
Ans. The proposed Bill replaces the demand-driven guarantee with centrally fixed financial allocations, removing the State’s obligation to provide work.

Q4. Why is the prohibition of work during peak agricultural seasons criticised?
Ans. The prohibition is criticised because it weakens workers’ bargaining power and forces them into exploitative agricultural employment.

Q5. What does the social composition of MGNREGA workers indicate?
Ans. The social composition indicates that Adivasis and Scheduled Castes disproportionately depend on MGNREGA, reflecting deep structural inequality.

A Bold Step Amid an Ambitious Nuclear Energy Target

Context

  • Human development is closely linked to rising energy consumption. Earl Cook’s 1971 Scientific American study showed that as societies evolved—from primitive to digital stages—their energy needs expanded steadily.
  • Today’s digital economy adds new, significant energy demands.
  • This article highlights how India’s pursuit of higher human development is inseparable from a massive expansion and decarbonisation of energy supply, placing nuclear power—and the SHANTI Bill, 2025—at the centre of its long-term development strategy.

Energy Growth Required for India’s Human Development Goals

  • Human Development Index (HDI) closely correlates with per capita Final Energy Consumption (FEC), linking development outcomes with energy availability.
  • As a G20-member aspiring to an HDI of 0.9 or higher, India would need to generate around 24,000 TWh of energy annually, even after accounting for improvements in energy efficiency and electrification.
  • Of this, about 60% would be used as electricity, while the remaining would go into hydrogen production via electrolysers, essential for decarbonising hard-to-abate sectors such as steel, fertilisers and plastics.
  • If alternative low-energy hydrogen production methods mature, electricity demand could reduce.
  • India’s electricity generation in 2023-24 was about 1,950 TWh, with a compound annual growth rate (CAGR) of ~4.8% in recent years. At this pace, reaching 24,000 TWh would take four to five decades.
  • However, two major challenges
    • First, India must decarbonise its energy mix while scaling generation.
    • Second, electrification of end uses must expand sharply, as electricity currently accounts for only about 22% of FEC.
  • Achieving development goals therefore requires not just higher generation, but a transition away from fossil fuels towards hydro, nuclear, solar and wind power, alongside systemic energy redesign.

Nuclear Power and India’s Decarbonised Energy Mix

  • Limits of Renewable Energy Sources

    • India’s hydro and wind potential is inherently limited, while high population density restricts the availability of land for large-scale solar photovoltaic deployment.
    • Although hydro, solar and wind must be fully utilised, their combined potential is insufficient to meet the energy levels required for India to achieve an HDI above 0.9.
    • As a result, nuclear power must be significantly expanded, and fossil fuels will remain necessary in the interim.
  • Need for Reliable Baseload Power

    • Solar and wind are intermittent energy sources, with output varying by time of day and season.
    • Large-scale electricity storage to balance this variability is costly and often economically unviable, especially for seasonal fluctuations.
    • To ensure affordable and reliable power, India’s energy mix requires baseload generation that is independent of weather or time.
    • Nuclear power plants provide stable baseload electricity, making them essential for a decarbonised system.
  • Indigenous Nuclear Capability

    • India has built strong indigenous capacity across the nuclear energy supply chain.
    • While uranium must be imported due to limited domestic reserves, the country has developed technologies for fuel fabrication, heavy water production, and equipment manufacturing.
    • The Nuclear Power Corporation of India Limited (NPCIL) has mastered the design and operation of Pressurised Heavy Water Reactors (PHWRs), including the 700 MW class.
  • Expansion of Nuclear Power

    • Currently, three 700 MW PHWR units are operational, a fourth is nearing completion, and two more are under advanced construction.
    • In 2017, the government approved the construction of 10 additional 700 MW PHWRs, with work progressing steadily, signalling a major scale-up of nuclear capacity.
  • Safety, Regulation and Waste Management

    • India established a nuclear regulatory body in the 1980s with robust oversight capabilities.
    • The Bhabha Atomic Research Centre (BARC) has developed technologies for reprocessing spent fuel and managing nuclear waste.
    • Together, these efforts make nuclear power a technically feasible, safe, and cost-effective pillar of India’s long-term decarbonised energy strategy.

The SHANTI Bill, 2025: A New Push for Nuclear Energy

  • Ambitious Nuclear Expansion Target

    • Building on recent successes in nuclear power, the Union government has set a target of 100 GW of installed nuclear capacity by mid-century.
    • It is planning for a major expansion of the sector to support long-term development and decarbonisation goals.
  • Consolidated Legal Framework

    • Parliament has passed the Sustainable Harnessing and Advancement of Nuclear Energy for Transforming India (SHANTI) Bill, 2025.
    • It is an overarching legislation that consolidates and harmonises provisions of the Atomic Energy Act, 1962 and the Civil Liability for Nuclear Damage Act, 2010.
  • Regulatory and Safety Provisions

    • The Bill provides continuity in regulation by stating that the Atomic Energy Regulatory Board (AERB) “shall be deemed to have been constituted under this Act.”
    • It clearly assigns the primary responsibility for safety, security and safeguards to the licensee of the nuclear facility, strengthening accountability.
  • Strategic Significance

    • With its ambitious capacity target and streamlined legal framework, the SHANTI Bill represents a bold policy step.
    • Such decisive measures, coupled with long-term vision, are viewed as essential for India’s transition to a developed, energy-secure and low-carbon economy.

A Bold Step Amid an Ambitious Nuclear Energy Target FAQs

Q1. Why is energy consumption closely linked to human development?

Ans. Human development rises with energy availability, as higher energy consumption supports income growth, education, healthcare, industrialisation and digitalisation across successive stages of societal advancement.

Q2. How much energy does India need to reach an HDI of 0.9?

Ans. Estimates suggest India must generate around 24,000 TWh annually, even with efficiency gains, to achieve an HDI of 0.9 comparable to advanced economies.

Q3. Why are renewables alone insufficient for India’s long-term energy needs?

Ans. Limited hydro and wind potential, land constraints for solar, and intermittency make renewables inadequate alone, necessitating reliable baseload sources like nuclear power.

Q4. What makes nuclear power essential in a decarbonised energy mix?

Identifying BS-VI Vehicles: How India Is Separating Clean Cars from Polluting Ones

BS-VI

BS-VI Latest News

  • The Delhi government has tightened vehicular pollution controls amid severe air quality, bringing renewed focus on Bharat Stage (BS) emission norms. 
  • Non-BS VI private vehicles registered outside Delhi have been barred from entering the city.
  • Fuel stations will now sell fuel only to vehicles with a valid Pollution Under Control Certificate (PUCC). 
  • Non-compliant vehicles face a fine of ₹20,000, while even BS-VI vehicles can be fined ₹10,000 if they lack a valid PUCC.
  • These measures target emissions from older, more polluting vehicles as part of efforts to curb worsening air pollution in the Capital.

Bharat Stage (BS) Emission Norms

  • Bharat Stage (BS) emission norms are India’s legally enforced standards to regulate air pollutants emitted by motor vehicles. 
  • Framed by the Ministry of Environment, Forest and Climate Change (MoEFCC) and implemented by the Central Pollution Control Board (CPCB), these norms are broadly aligned with European emission standards (Euro norms) and apply to all new vehicles manufactured and sold in the country.

Evolution of Bharat Stage Norms

  • India has progressively tightened vehicular emission standards to address worsening urban air pollution:
    • BS I – Introduced nationwide in 2000
    • BS II – 2001 (Delhi first), nationwide by 2005
    • BS III – Nationwide by 2010
    • BS IV – Nationwide by 2017
    • BS VI – Implemented directly from BS IV in April 2020, skipping BS V

Pollutants Regulated

  • BS norms prescribe upper limits for key vehicular pollutants, including:
    • Carbon Monoxide (CO)
    • Hydrocarbons (HC)
    • Nitrogen Oxides (NOx)
    • Particulate Matter (PM)
  • Each successive BS standard tightens these limits significantly.

Other Features

  • Advanced emission-control technologies, such as:
    • Diesel Particulate Filters (DPF)
    • Selective Catalytic Reduction (SCR)
    • On-board diagnostics (OBD)
  • More realistic testing aligned closer to real driving conditions.

Significance of Bharat Stage Norms

  • Public health protection by reducing pollutants linked to respiratory and cardiovascular diseases.
  • Environmental benefits, including lower smog formation and black carbon emissions.
  • Technological upgradation of India’s automobile industry.
  • Global alignment, improving export competitiveness of Indian vehicles.

Why Delhi Has Mixed-Standard Vehicles

  • Delhi’s mixed BS fleet exists because the Capital adopted stricter norms earlier than the rest of India due to severe air pollution. 
  • Delhi implemented BS II in 2001, BS III in 2005 and BS IV in 2010—well ahead of national timelines. 
  • Although BS VI became mandatory nationwide in April 2020, vehicles from other states with older standards continue to enter the city, resulting in a mix of emission norms on Delhi’s roads.

Why Older Vehicles Contribute More to Air Pollution

  • Older vehicles emit significantly higher levels of harmful pollutants because they lack advanced emission-control technologies. 
  • Diesel vehicles, in particular, release large amounts of nitrogen oxides and fine particulate matter, major contributors to smog and respiratory and cardiovascular diseases.
  • They also emit volatile organic compounds that form secondary pollutants in the atmosphere. 
  • In addition, black carbon from diesel exhaust not only damages public health but also accelerates climate warming, making older vehicles especially polluting.

Scale of Older, High-Polluting Vehicles in Delhi-NCR

  • A significant share of vehicles in Delhi-NCR remains highly polluting. 
  • Government assessments indicate that nearly 37% of vehicles in the region comply only with older Bharat Stage I, II or III norms, making them major contributors to the air quality crisis.

BS VI vs BS IV: What Changed in Emission Standards

  • BS VI emission norms impose far tighter pollution limits than BS IV. 
  • For petrol vehicles, nitrogen oxide (NOx) limits are reduced by about 25%. 
  • For diesel vehicles, NOx emissions must fall by nearly 68%, while particulate matter (PM) emissions are cut by around 82%.
  • BS VI vehicles also run on much cleaner, low-sulphur fuel, enabling advanced emission-control technologies to operate effectively. 
  • In addition, BS VI introduces more stringent testing procedures, closer to real-world driving conditions, to ensure lower on-road emissions.

  • Microprocessors form the core of modern digital infrastructure, powering telecommunications, industrial automation, defence systems, automobiles, and consumer electronics. 
  • Dependence on imported processors exposes India to supply disruptions, export controls, and cybersecurity vulnerabilities.
  • Recognising this strategic vulnerability, the Government of India has consistently pushed for “homegrown processor technology” as part of its broader vision of technological sovereignty and digital resilience.

About DHRUV64

  • DHRUV64 is a 64-bit, dual-core general-purpose microprocessor developed by C-DAC under MeitY’s Microprocessor Development Programme
  • Operating at a clock speed of 1 GHz, it is designed to strike a balance between computational capability and energy efficiency.
  • Unlike simple microcontrollers used for basic sensing tasks, DHRUV64 is capable of running modern operating systems and handling more complex workloads. 
  • Its intended applications range from consumer electronics to industrial automation and embedded systems, where reliability and integration matter more than peak computing power.

Technical Significance of the Processor

  • From a technological perspective, DHRUV64 does not compete with high-end smartphone or laptop processors that feature multiple cores, advanced GPUs, and high clock speeds. 
  • Instead, it targets sectors such as telecommunications equipment, industrial controllers, routers, and automotive modules, where stable performance, long lifecycle support, and secure architectures are crucial.
  • Such sectors value hardware-software integration and predictable behaviour rather than raw speed. 
  • This makes DHRUV64 relevant for strategic and infrastructure-related applications rather than mass consumer devices.

Role of RISC-V and the DIR-V Programme

  • A key feature of DHRUV64 is that it is based on the RISC-V instruction set architecture. 
    • RISC-V is an open-source instruction set, meaning that its design rules are publicly available and can be used without paying licensing fees.
  • This openness allows countries like India to design processors without dependence on proprietary architectures controlled by foreign companies. 
  • RISC-V is also modular, enabling designers to customise processors for specific tasks such as security, performance, or energy efficiency.
  • DHRUV64 is part of the Digital India RISC-V (DIR-V) programme, which aims to develop a portfolio of indigenous processors for civilian, industrial, and strategic uses. 
  • Earlier processors under this ecosystem include SHAKTI (IIT-Madras), AJIT (IIT-Bombay), VIKRAM (ISRO-SCL), and THEJAS processors developed by C-DAC.

Concerns and Information Gaps

  • Despite its strategic importance, MeitY’s announcement leaves several critical questions unanswered. 
  • The government has not provided detailed performance benchmarks, memory architecture details, or power efficiency metrics, which are essential for industrial adoption.
  • There is also limited clarity on fabrication details, such as the manufacturing foundry, process node, yields, and long-term reliability. 
  • Additionally, the term “fully indigenous” remains ambiguous, as it can refer to different aspects such as design, toolchains, fabrication, or ownership of intellectual property.
  • The absence of a clear deployment roadmap, operating system support, and government procurement plans may slow industry adoption in the short term.

Way Forward for India’s Chip Ecosystem

  • DHRUV64 must be viewed as a foundational step rather than a finished solution. 
  • Its success will depend on the creation of a supporting ecosystem that includes developer boards, software tools, skilled manpower, and anchor government demand.
  • Complementary initiatives such as Chips to Startup Programme, Design Linked Incentive Scheme, and the India Semiconductor Mission are critical to building fabrication capacity, nurturing startups, and expanding semiconductor talent in India.
  • The long-term goal is to enable Indian consumers and industries to adopt indigenous processors without compromising on cost, security, or reliability.
