Environment & Ecology | Biodiversity | Tribal Livelihoods | Non-Timber Forest Produce

Why in the news?

Rugda, a prized wild mushroom of Jharkhand’s Sal forests, has gained attention for its ecological importance and contribution to tribal livelihoods. It is a seasonal source of food and income, particularly for forest-dependent communities during the monsoon. 

About Rugda Mushroom

• Scientific name: Astraeus hygrometricus; related species such as Astraeus asiaticus are also locally identified as Rugda.
• Type: Wild, edible, subterranean fungus, commonly known as an earthstar mushroom.
• Distribution: Jharkhand and adjoining regions of Odisha, Chhattisgarh, West Bengal and Bihar.
• Habitat: Primarily found in Sal-dominated forests of the Chhotanagpur Plateau.
• Season: Appears beneath the forest floor after the first monsoon showers and is collected for a short period.
• Local names: Rugda, Rugra, Futka and Puttu. 

Ecological significance

• Ectomycorrhizal association: Rugda forms a symbiotic relationship with the roots of Sal (Shorea robusta) trees.
• Nutrient exchange: Fungal filaments help trees absorb water and minerals from the soil; in return, the fungus receives carbohydrates produced through photosynthesis.
• Soil health: Contributes to nutrient cycling and the functioning of forest ecosystems.
• Forest dependence: Its life cycle depends on healthy host trees, soil conditions and adequate monsoon moisture.
• Cultivation challenge: It is difficult to cultivate artificially because it depends on a living forest ecosystem. 

Economic and social significance

• Non-Timber Forest Produce (NTFP): Provides seasonal income to tribal households.
• Women’s role: Traditional knowledge of locating and identifying edible mushrooms is largely passed down through generations of women.
• Food security: Adds nutritional diversity during the monsoon and agricultural lean season.
• Market value: Its limited availability and high demand make it a high-value forest product.
• Traditional knowledge: Indigenous communities use local knowledge to distinguish edible Rugda from poisonous wild mushrooms. 

Conservation concerns

• Loss and fragmentation of Sal forests.
• Erratic monsoon patterns and changing soil-moisture conditions.
• Unsustainable harvesting and rising commercial demand.
• Declining transmission of traditional ecological knowledge.

GS III – Economy / GS II – Governance
Disinvestment, Public Sector Enterprises, and Fiscal Management

Introduction

Amid global uncertainty, high energy prices and monsoon concerns, disinvestment and asset monetisation have supported fiscal receipts in 2026–27. The proposed IDBI Bank stake sale (October 14) could push receipts beyond the budget target, signalling continued commitment to reforms and private-sector participation. Calibrated disinvestment can serve as an interim strategy while broader PSE privatisation progresses.

The Disinvestment Trajectory

Collections (April-September 2026)

• Total Mobilised: ₹62,124 crore (disinvestment and asset monetisation).
• Disinvestment Component: ₹55,757 crore.
• Budget Target: ₹80,000 crore—collections already reached 78%.
• IDBI Bank Sale: Approval on October 14; proceeds to push collections past the target.

Fiscal Context

• Net Tax Revenue: Modest 3.4% growth (April-August 2026).
• Non-Tax Revenue: 3.2% growth.
• Capital Expenditure: Up over 18%.
• Fiscal Deficit: Already 42% of budgeted levels—implying a tight balance between revenue shortfalls and spending risks.

Why Disinvestment Matters

Revenue Diversification

• Rising Expenditure Commitments: Need to diversify revenue sources.
• Fiscal Space: Disinvestment provides non-tax revenue without raising taxes or cutting spending.
• Capital Expenditure: Supports public investment while maintaining fiscal discipline.

Reform Signal

• Commitment to Reforms: Continued role for the private sector.
• Investor Confidence: Signals government’s willingness to divest.
• Efficiency: Private sector participation can improve PSE performance.

Interim Measure

• Privatisation is Long: Several PSEs require complex processes—valuation, legal, employee concerns.
• Calibrated Disinvestment: Minority stake sales, IPOs, strategic sales—can proceed in phases.
• Bridge: Provides resources while structural reforms continue.

Challenges

• Valuation: Timing and pricing of stake sales.
• Market Absorption: Large sales may depress prices.
• Employee Concerns: Job security; transition issues.
• Strategic vs. Non-Strategic: Distinguishing sectors where government presence is essential.
• Use of Proceeds: Should fund capital expenditure, not revenue deficits.

Way Forward

• Calibrated Approach: Phased disinvestment; strategic sales where appropriate.
• Strengthen DIPAM: Capacity for valuation, transaction management.
• Employee Protection: Address concerns through VRS, retraining.
• Use of Proceeds: Ring-fence for capital expenditure; infrastructure.
• Transparency: Regular disclosure of targets and achievements.

Conclusion

Disinvestment and asset monetisation mobilised ₹62,124 crore in April–September 2026 (78% of the ₹80,000 crore target), with the IDBI Bank sale likely to boost receipts. Despite modest tax revenue growth of 3.4%, capital expenditure rose over 18%, while the fiscal deficit reached 42% of the budgeted level.

Practice Question

1. Given that privatisation of several PSEs is a long journey, calibrated disinvestment could serve as an interim measure. Critically examine the role of disinvestment in India’s fiscal strategy and suggest measures for effective implementation. (250 words, 15 marks)
