Context:  India successfully test-fired the Agni-Prime (Agni-P) ballistic missile from a rail-based mobile launcher, marking a strategic milestone. 

The Defence Research and Development Organisation (DRDO) tested the Agni-P missile from a rail-based launcher, placing India among a select group of nations with such “canisterised launch systems.” Rail-based platforms enhance second-strike capability by providing mobility, concealment, and survivability against enemy surveillance compared to vulnerable fixed silos. They are cheaper and easier to scale than submarine-based systems, leveraging India’s extensive railway network. Agni-P, a two-stage solid-fuel missile with a range of 1,000–2,000 km, succeeds Agni-I with improved guidance, propulsion, and warhead technology.

Context : The Supreme Court struck down Rajasthan’s 2007 VAT exemption on locally made goods, ruling that taxation cannot discriminate against goods from other states.

The Supreme Court quashed a Rajasthan notification that exempted VAT on locally manufactured asbestos sheets and bricks, which disadvantaged goods imported from other states. The bench held this violated Article 304(a) of the Constitution, which prohibits states from imposing discriminatory taxes on out-of-state goods. The Court emphasized that taxation cannot be used as a tool to restrict trade or create unfair advantages for local products, reaffirming the principle of free and non-discriminatory trade across India.

Learning Corner:

Article 304(a) of the Constitution:

• Provision: Article 304(a) of the Indian Constitution allows State Legislatures to impose taxes on goods imported from other States or Union Territories, but such taxation cannot discriminate between imported goods and similar goods produced within the State.
• Objective: To ensure free trade, commerce, and intercourse throughout India (as guaranteed under Article 301) while permitting States to levy taxes for revenue purposes.
• Key Principle: Taxes must be non-discriminatory—i.e., goods from other States should not be treated unfavorably compared to locally produced goods.
• Judicial Interpretation: The Supreme Court has consistently held that taxation cannot be used as a weapon to create economic barriers or protectionism within a State. Discriminatory tax laws violate the spirit of national economic unity.

Introduction (Context) 

India’s export economy is heavily skewed, with Gujarat, Maharashtra, Tamil Nadu, and Karnataka accounting for over 70% of exports while populous states like UP, Bihar, and MP together contribute barely 5%. 

Despite sharing 5,400 km of international borders, the northeastern states remain almost absent from the trade map, with just 0.13% of exports, reflecting a critical neglect of regions vital for a balanced economy.

Marginalisation of the Northeast

• No operational trade corridor links the region to foreign markets.
• Presence of no logistical infrastructure to support volume or role in shaping policy. Instead there is the existence of security apparatus calibrated for counterinsurgency and surveillance. 
• Key export policies and schemes like Remission of Duties and Taxes on Exported Products and Production-Linked Incentives are designed for industrial belts in western and southern India.
• Institutions shaping India’s export strategy e.g., PM’s Economic Advisory Council lack representation from the Northeast.
• The Board of Trade, tasked with steering India’s export strategy, has no substantive voice from Mizoram, Tripura, or Arunachal Pradesh
• DGFT’s 2024 export plan of 87 pages carried no substantive section on the Northeast.
• Assam’s tea economy, producing over half of India’s tea, faces stagnant prices, labour shortages, and exposure to Western tariff hikes.
• Numaligarh refinery expansion increases dependence on Russian cargoes, making it vulnerable to geopolitical sanctions.

India-Myanmar relations

• Since the 2021 coup in Myanmar, trade across the India–Myanmar border has sharply declined, with once-active highways now reduced to checkpoints and bureaucratic delays.
• Key gateways Zokhawthar (Mizoram) and Moreh (Manipur) have become securitised bottlenecks instead of trade hubs, lacking proper roads, customs staff, and cold-chain facilities.
• The 2024 scrapping of the Free Movement Regime severed cross-border trade, kinship ties, and local hill economies.
• Surveillance has replaced commerce, turning trade corridors into containment zones where troops move but goods do not.
• The Northeast, once envisioned as India’s bridge to ASEAN, remains excluded from national trade strategy, with policy still focused on traditional western and southern export corridors.
• The India–Myanmar–Thailand Trilateral Highway remains incomplete and underutilised.

While China consolidates influence in northern Myanmar through infrastructure and alliances, India’s Act East policy remains largely rhetorical. The absence of trade infrastructure cedes economic and strategic ground to regional competitors.

Implications

• India’s exports are concentrated in a few coastal states, so even a natural disaster in Gujarat or a labour strike in Tamil Nadu can disturb the entire national export chain.
• Leaving the Northeast out of trade planning weakens India’s influence in Southeast Asia and limits its role in the wider Indo-Pacific region.
• Continuous neglect of the region increases feelings of isolation, reducing job opportunities and fuelling resentment among local communities.

Way Forward

• Build strong basic infrastructure like highways, warehouses, cold storage and border trade facilities instead of relying only on policy announcements.
• Give the Northeast proper representation in export policy bodies so that its needs and opportunities are part of national trade decisions.
• Activate projects like the India–Myanmar–Thailand Highway and reopen key cross-border trade routes with ASEAN to connect the region to foreign markets.
• Encourage industries to set up export units in border states by offering targeted PLI schemes, tax incentives, and logistics support.
• Treat trade geography as part of national security planning to counter China’s growing influence in Myanmar and the Bay of Bengal.

Conclusion

India cannot aspire to regional leadership while its eastern flank stays economically weak. True resilience demands spreading trade opportunities nationwide and giving the Northeast real infrastructure, policies, and market access, not just symbolic inclusion.

Mains Practice Question

Q  Why does India’s Northeast contribute so little to exports, and how can the region be better integrated into the national trade strategy? (250 words, 15 marks)

Introduction

River pollution continues to be a critical environmental and public health issue in India. Polluted rivers affect aquatic ecosystems, compromise water quality, and threaten livelihoods dependent on rivers.
CPCB has recently released data on river pollution, hereby discussing the key findings.

Key findings

• CPCB reviewed water quality data from 2,116 locations across 32 states and Union Territories (2022–2023) and found 296 polluted river stretches on 271 rivers. The number has marginally decreased from 311 in the previous report.
• Priority I (most polluted): Out of 296 stretches, 37 were classified as critically polluted (BOD > 30 mg/L), slightly lower than 46 in the previous report.
• State-wise distribution: Tamil Nadu, Uttar Pradesh, and Uttarakhand reported the highest number (five each) of Priority I stretches; Gujarat (four) and Karnataka (three) also featured prominently.
• Notable polluted stretches: Yamuna (Palla–Asgarpur, Delhi), Sabarmati (Ahmedabad), Chambal (Nagda–Gandhisagar, MP), Tungabhadra (Karnataka), Sarabanga (Tamil Nadu).
• Rivers with deteriorated water quality: Jhelum (J&K), Ganga, Ramrekha, Sikrahna (Bihar), Hasdeo, Mahanadi (Chhattisgarh), Sal, Mapusa (Goa), Cauvery, Tungabhadra (Karnataka), Periyar (Kerala), Amba, Savitri (Maharashtra), Krishna (Telangana), Kosi (Uttarakhand).
• Maharashtra has the highest number (54) of polluted river stretches.

Terminologies

• Biochemical Oxygen Demand (BOD): BOD measures the amount of oxygen required by microorganisms to decompose organic matter in water. Locations with BOD > 3 mg/L are considered polluted and unsuitable for bathing.
• Polluted River Stretch: It is the continuous sequence of two or more polluted locations along a river. High BOD levels indicate excessive organic and chemical pollution, impacting aquatic life and human health.
• Priority Categories of River Water Quality:

• • Priority I: Critically polluted (BOD > 30 mg/L)
  • Priority II: Severely polluted (BOD 20–30 mg/L)
  • Priority III: Moderately polluted (BOD 10–20 mg/L)
  • Priority IV: Less polluted (BOD 6–10 mg/L)
  • Priority V: Non-polluted (BOD 3–6 mg/L)

• Water (Prevention and Control of Pollution) Act, 1974: Provides a legal framework for preventing and controlling water pollution.
• CPCB: Central body for planning, regulating, and enforcing water quality standards.
• SPCBs: State-level institutions responsible for implementing water quality norms.
• National Water Quality Monitoring Programme (NWQMP): Launched in 1978 under GEMS-Water programme to continuously track water quality across India.

Reasons for River Pollution

• Untreated Sewage: Over 60% of sewage is released untreated into rivers daily, causing severe health risks and ecological damage.
• Industrial Effluents: Toxic wastewater from chemical, sugar, paper, and tannery industries contaminates water with hazardous chemicals.
• Agricultural Runoff: Pesticides, fertilizers, and nutrient-rich runoff increase BOD levels and cause eutrophication.
• Sand Mining and Illegal Encroachment: Disrupt natural river flow, increase flood risk, and contribute to sediment and pollutant accumulation.
• Other Factors: Solid waste dumping, urbanisation along riverbanks, and lack of proper drainage infrastructure.

Impact of River Pollution

• Environmental Impact: Loss of aquatic biodiversity, ecosystem degradation, and altered river morphology.
• Health Impact: Waterborne diseases like cholera, diarrhea, and skin infections among communities dependent on rivers
• Economic Impact: Reduced agricultural productivity, fisheries decline, and increased water treatment costs.
• Social Impact: Disruption of cultural and religious practices tied to rivers.

Government initiatives

• Namami Gange Programme (NGP): It is the holistic river basin management programme to abate pollution and restore Ganga’s ecological health through sewage treatment, riverfront development, and community participation.
• Yamuna Action Plan (YAP): Focuses on reducing Yamuna pollution via sewage treatment, industrial effluent control, and inter-state coordination.
• State-level river rejuvenation schemes: Programs like Mukhyamantri Jal Samvardhan Yojana clean local rivers and prevent untreated sewage discharge.
• Industrial effluent regulation: CPCB and SPCBs monitor and enforce wastewater treatment norms for industries.
• Real-time water quality monitoring: Sensor-based and GIS-linked systems track BOD, COD, and other parameters for timely intervention.
• Agricultural runoff management: Promotes organic farming, bio-remediation, and controlled use of fertilizers and pesticides.

Challenges

• Inadequate sewage treatment and poor infrastructure result in untreated sewage entering rivers.
• Insufficient enforcement of industrial effluent norms leads to continued chemical contamination.
• Agricultural runoff with fertilizers and pesticides increases nutrient load, causing eutrophication.
• Rapid urbanisation, sand mining, and encroachments disrupt river flow and add to pollution.
• Inter-state coordination issues hinder comprehensive river management.
• Lack of public awareness and limited community participation slows pollution control efforts.

Way Forward

• Strengthen sewage and industrial wastewater treatment infrastructure and ensure strict enforcement of laws.
• Promote river basin management with inter-state coordination and scientific monitoring.
• Encourage community engagement, public awareness campaigns, and adoption of sustainable farming practices.
• Implement real-time water quality monitoring and early warning systems for timely interventions.
• Expand programmes like Namami Gange and Yamuna Action Plan to cover more rivers and stretches.

Conclusion 

River pollution in India continues to threaten ecosystems, public health, and livelihoods. Despite slight improvements, effective pollution control requires strict law enforcement, technology-driven monitoring, and active community participation to restore rivers and secure water resources.

Mains Practice Question

Q  Examine the major causes and impacts of river pollution in India. Evaluate the effectiveness of government initiatives and suggest measures to improve river water quality. (250 words, 15 marks)
