Hog in the Limelight: Pygmy Hog Conservation Programme and Grassland Ecosystem Restoration

Prelims: Porcula salvania, Manas NP, IUCN Status Mains: Wildlife Conservation & Grassland Ecology State PCS: Assam APSC & North-East Ecology

1 Ecological Status & Umbrella Species Significance

Core Editorial Insights & Species Profile

Sole Surviving Species: The Pygmy Hog (Porcula salvania) is the sole surviving species of the genus Porcula and the world's smallest and rarest wild suid.
Indicator of Floodplain Health: The species depends entirely on dense, tall alluvial wet grasslands to feed, conceal itself, and reproduce; distress among pygmy hogs directly mirrors the degradation of India's alluvial riverine floodplains.
Umbrella Protection: Progress under the Pygmy Hog Conservation Programme and Grassland Ecosystem Restoration extends vital protections to co-occurring threatened fauna, including the Bengal Florican, Hispid Hare, Hog Deer, and Greater One-Horned Rhinoceros.
Captive Breeding Feat: Initiated in 1995 (led by Durrell Wildlife Conservation Trust, Assam Forest Dept, and MoEFCC), captive breeding expanded the population 32-fold over 30 years from a tiny founder stock.

2 Ecological Threats & Genetic Bottlenecks

Habitat Degradation & Encroachment

Conversion of riverine floodplains for agricultural expansion, tea estates, flood embankment infrastructure, invasive alien weeds, and unscientific dry-season grassland burning have severely fragmented their micro-habitat.

Inbreeding & Disease Vulnerability

Because all captive individuals originate from a narrow genetic founder stock, the Pygmy Hog Conservation Programme and Grassland Ecosystem Restoration must manage pedigree tracking and stringent biosecurity against lethal swine diseases.

3 Strategic Roadmap for Protected Grasslands

1. Panbari Stronghold

Securing the last surviving natural wild population in the Panbari grasslands of Manas National Park.

2. New Reintroduction Sites

Expanding viable populations across Orang National Park, Sonai Rupai Wildlife Sanctuary, Rupahi, and Kanchanbari.

3. Scientific Habitat Management

Balancing fire regimens to prevent tree/shrub encroachment into grasslands through the Pygmy Hog Conservation Programme and Grassland Ecosystem Restoration.

4. 2040 Target Vision

Scaling wild numbers past 300 individuals while restoring continuous ecological buffer corridors across the Assam duars.

Long-term evolutionary fitness cannot rely indefinitely on captive insurance populations; the Pygmy Hog Conservation Programme and Grassland Ecosystem Restoration must be anchored in restored natural alluvial ecosystems.

GS Paper II Indian Polity & Governance Fiscal Federalism & Constitutional Law

Mining Amendment is Unfair to States: MMDR Amendment Act 2026 Section 9D and Mineral Taxation Federalism

Prelims: Entry 49 & 50 List II, MADA 2024 SC Ruling Mains: Centre-State Fiscal Relations & Mining State PCS: Mineral Revenues in Odisha, JH, CG

1 Section 9D Contention & Centre vs States Conflict

Ashok Kumar Panda & Aniruddha Purushotham's Legal Analysis

Core Provision of Section 9D: The Mines and Minerals (Development and Regulation) Amendment Act, 2026 introduces Section 9D, restricting State Governments from levying taxes, cesses, or imposts on mineral rights or mineral-bearing land without Central approval.
Centre's Justification: The Union argues that MMDR Amendment Act 2026 Section 9D and Mineral Taxation Federalism establishes tax predictability, prevents excessive state taxation, and encourages foreign/domestic investments.
Negative Externalities Borne by States: Mineral-rich states (Odisha, Jharkhand, Chhattisgarh, Karnataka) bear the direct social, environmental, displacement, and infrastructural rehabilitation costs of mining.
Fiscal Health Impact: Mining revenues form the backbone of non-tax revenue for resource-rich states, recognized in NITI Aayog's Fiscal Health Index.

2 Constitutional Dilemma: Entry 49 & 50 vs 9-Judge SC Ruling

Constitutional Dimension	State List (List II) Mandate	Impact of MMDR 2026 Section 9D
Entry 50 (Mineral Rights)	States can tax mineral rights, subject to limitations imposed by Parliament relating to mineral development.	Restricts states from enacting independent state-level mineral cess frameworks.
Entry 49 (Land & Buildings)	Exclusive and plenary legislative domain of States to tax lands and buildings.	Extends restrictions to levies on mineral-bearing land, encroaching on Entry 49.
2024 SC MADA Ruling	9-judge Bench held royalty is NOT a tax and affirmed States' power to tax mineral-bearing land.	MMDR Amendment Act 2026 Section 9D and Mineral Taxation Federalism risks rendering the landmark SC judgment nugatory.

3 Federal Balance & Asymmetric Resource Burden

Responsibility Without Fiscal Autonomy

States bear long-term ecological restoration and public infrastructure wear-and-tear costs. Limiting their taxation rights under MMDR Amendment Act 2026 Section 9D and Mineral Taxation Federalism creates structural fiscal deficits.

Predictability vs Federal Autonomy

While uniform investor rules are important, MMDR Amendment Act 2026 Section 9D and Mineral Taxation Federalism cannot substitute executive fiat for constitutional powers vested in state legislatures.

✎ Prelims Practice Question

Q2. Regarding the legislative and taxation powers over minerals in India, consider the following statements:

1. Under Entry 50 of the State List, the State legislature has the power to tax mineral rights, subject to limitations imposed by Parliament.
2. The Supreme Court in the 2024 Mineral Area Development Authority (MADA) case ruled that royalty payable under the MMDR Act is a tax.
3. Entry 49 of the State List confers plenary power on State legislatures to levy taxes on lands and buildings, including mineral-bearing lands.

Which of the statements given above are correct?

A) 1 and 2 only
B) 1 and 3 only
C) 2 and 3 only
D) 1, 2 and 3

Correct Answer: B — 1 and 3 only

Statement 2 is incorrect because the 9-judge Constitution Bench in 2024 conclusively held that royalty is a statutory charge/consideration for extracting minerals and is NOT a tax. Statements 1 and 3 are correct.

🏆 UPSC CSE Prelims 2016 (Actual PYQ)

Q. What is/are the purpose/purposes of District Mineral Foundations (DMF) in India?

1. Promoting mineral exploration activities in mineral-rich districts.

Select the correct answer using the code given below:
A) 1 and 2 only B) 2 only C) 1 and 3 only D) 1, 2 and 3

A) 1 and 2 only
B) 2 only
C) 1 and 3 only
D) 1, 2 and 3

Correct Answer: B — 2 only

UPSC CSE Mains 2022 — GS Paper II (Actual PYQ)

“The role of the Supreme Court of India in preserving fiscal federalism and resolving Centre-State legislative conflicts is pivotal. Critically examine.” (15 Marks | 250 Words)

Mains Model Answer Framework (15 Marks | 250 Words)

“Evaluate the constitutional and fiscal implications of centralizing mineral taxation regulations in India. Can ease of doing business justify circumscribing state taxation powers?”

Key Answer Structuring

Introduction: Contextualize the debate surrounding MMDR Amendment Act 2026 Section 9D and Mineral Taxation Federalism following the landmark 2024 SC 9-judge ruling.
Arguments for Centralization: Reducing cascading tax disputes, fostering long-term mining FDI, and establishing uniform commodity pricing.
Constitutional & Federal Counter-arguments: Encroachment upon Entry 49 (List II), denial of resource rents to host states facing social/ecological degradation, and erosion of cooperative federalism.
Way Forward: Structured GST-Council-like mineral coordination body rather than unilateral statutory restrictions.

GS Paper III Indian Economy & Agriculture Energy Security & Trade Dynamics

What Lies Beyond India's E20 Push: India E20 Ethanol Blending Economic Impact and Food Security

Prelims: E20 Fuel, Sugarcane/Maize Feedstock, OMCs Mains: Energy Policy, Food Security & Emissions State PCS: Agro-economics & Fuel Pricing

1 The E20 Promise vs Ground Realities

DevMac Economic Notes by Rohit Azad, Shouvik Chakraborty & Indranil Chowdhury

Composition: E20 petrol comprises 20% anhydrous ethanol blended with 80% motor gasoline, rolled out nationwide from February 6, 2023.
Three Core Rationales: The policy promised consumer savings, reduced carbon emissions, and substantial crude oil foreign exchange savings.
Mileage Penalty: Ethanol has lower calorific energy density than pure petrol. Nitin Gadkari (MoRTH) confirmed a 2% to 6% fuel economy drop in Lok Sabha, with older (pre-2022) cars experiencing even steeper drops.
Consumer Burden: Over the last 3 years, India E20 Ethanol Blending Economic Impact and Food Security research estimates Indian motorists spent ₹88,234 crore extra in fuel costs to cover the same mileage.

2 Agriculture, Trade Balance & Food Security Impacts

Agricultural Commodity	Trade & Market Shock	Macroeconomic Implication
Sugarcane Feedstock	Diversion to ethanol prompted domestic sugar export bans (2023 onwards), plunging export earnings from $6B to below $2B.	Loss of foreign exchange earnings from agricultural commodity exports.
Maize Feedstock	Rising ethanol feedstock share turned India from a net exporter of maize into a net importer.	Inflationary pressure on poultry, animal feed, and domestic food supply chains.
Net Forex Savings	Crude import reductions are partially negated by agricultural export losses under India E20 Ethanol Blending Economic Impact and Food Security.	Narrow net current account benefit with higher agricultural commodity volatility.

3 Policy Alternatives: Beyond Mandatory Blending

1. Countercyclical Fuel Taxes

Utilizing flexible indirect taxes to insulate consumers during global crude oil spikes without mandatory blend penalties.

2. Dual Fuel Choice

Offering consumers transparent at-the-pump options between E10 and E20, as suggested by the Chief Economic Adviser (CEA).

3. Public Transport Overhaul

Evaluating India E20 Ethanol Blending Economic Impact and Food Security to reallocate capital into electric buses and walking/cycling networks.

4. Targeted 2G Ethanol

Prioritizing 2nd generation agricultural residue/stubble ethanol rather than diverting food crops like sugarcane and maize.

Balancing energy security with domestic nutrition requires addressing the true multi-sector trade-offs of India E20 Ethanol Blending Economic Impact and Food Security.

✎ Prelims Practice Question

Q3. With reference to India's Ethanol Blended Petrol (EBP) Programme and Biofuel Policy, consider the following statements:

1. Anhydrous ethanol blended with petrol has a lower energy density (calorific value) than standard pure gasoline.
2. Under the National Biofuels Policy, surplus food grains like maize and damaged food grains are permitted feedstocks for 1G ethanol.
3. E20 petrol blend completely eliminates greenhouse gas emissions across all passenger vehicles regardless of vehicle vintage.

Which of the statements given above is/are correct?

A) 1 and 2 only
B) 2 and 3 only
C) 1 and 3 only
D) 1, 2 and 3

Correct Answer: A — 1 and 2 only

Statement 3 is incorrect because older non-E20-compliant engines experience mileage drops that offset per-litre emission gains, resulting in net-positive emissions over long distances. Statements 1 and 2 are correct.

Way Forward: Accelerated adoption of 2G lignocellulosic ethanol, dual-fuel choice at fuel stations, and prioritized public transit electrification.

❓ Frequently Asked Questions (17 September 2026 FAQs)

1. Why is the Pygmy Hog considered an indicator species for alluvial grasslands?

The pygmy hog (Porcula salvania) relies exclusively on tall, dense alluvial wet grasslands for nesting, foraging, and predator evasion. Habitat degradation, dry-season burning, or tree encroachment directly causes rapid decline in their population.

2. How does Section 9D of the MMDR Amendment Act 2026 impact fiscal federalism?

Section 9D restricts State Governments from levying taxes or cesses on mineral rights and mineral-bearing land without Central approval, potentially overriding the 2024 Supreme Court 9-judge bench ruling in the MADA case under Entry 49 and 50 of the State List.

3. What are the major trade and food security trade-offs of India's E20 petrol push?

Diverting sugarcane and maize toward ethanol production caused domestic sugar export bans (falling from $6B to under $2B) and shifted India into a net importer of maize, while consumer mileage loss resulted in estimated extra fuel expenditure of ₹88,234 crore.

4. What is the historical significance of the 2024 MADA vs SAIL Supreme Court judgment?

The 9-judge Constitution Bench held that royalty is not a tax and affirmed States' constitutional power under Entry 49 of List II to tax mineral-bearing land, upholding states' fiscal autonomy.

5. Which protected areas in Assam are critical for the Pygmy Hog reintroduction?

Manas National Park (Panbari grassland), Orang National Park, Sonai Rupai Wildlife Sanctuary, and newly identified restoration sites such as Rupahi and Kanchanbari.
