GS III – Agriculture / GS III – Environment
Renewable Energy, Land-Use Efficiency, and Farmer Income

Introduction

Agrivoltaics (agrisolar) combines crop cultivation with solar power generation on the same land, enabling farmers to diversify incomes while supporting clean energy. With agriculture supporting 46.1% of the population and nearly 55% of India’s land being agricultural, it offers opportunities to improve land-use efficiency, strengthen farm incomes, and enhance food and energy security.

Understanding Agrivoltaics

Key Elements

• Elevated Solar Structures: Panels mounted high enough to let sunlight and rain reach crops below; farmers can move equipment underneath.
• Partial Shading: Protects crops from extreme heat; reduces water evaporation from soil; creates cooler, more stable environment—especially in hot or dry regions.
• Dual Land Productivity: Integrates crop cultivation or livestock rearing with solar power generation; supplies electricity for farm activities; additional revenue through surplus power sales to grid.

India’s Current Status (As of August 2025)

• Operational Projects: 36 with installed capacity of 37.54 MW.
• Pilot Projects: 10 under development.
• Diversity: Elevated structures, interspace layouts, tracking systems across agroclimatic regions.

India’s Potential

• Estimates: Between 3,000 GW and nearly 14,000 GW.
• Farmer Income: Annual earnings could rise from around ₹60,000 per acre to over ₹1 lakh per acre.

Scope for Development

Land Suitability

• GIS-Based National Screening: Identified 47.35 million hectares of “restricted cropland” suitable for AgriPV after applying environmental, agronomic, and technical filters.

Crop Compatibility

• Promising Options: Fruits, vegetables, spices, medicinal plants.

High-Potential States

• Leaders: Maharashtra, Rajasthan, Andhra Pradesh, Madhya Pradesh, Karnataka, Uttar Pradesh—collectively account for nearly 50% of India’s estimated AgriPV power generation potential.
• Drivers: Cropland availability, solar resource, agro-climatic conditions.
• Moderate Potential: Odisha, Tamil Nadu, Kerala, Telangana, Bihar, West Bengal.
• Most Favourable Regions: Southern, western, and central—combination of solar irradiance, land availability, horticultural intensity.

Government Initiatives

PM KUSUM (February 2019)

• Objective: Encourage solar energy adoption in agriculture; reduce dependence on diesel; diversify farmer earnings.
• Central Financial Assistance: ~₹34,422 crore.
• Features: Decentralised solar power generation; solarisation of agricultural pumps.

• Launched: 2023; anchored by National Solar Energy Federation of India (NSEFI).
• Members: 40+.
• Functions: Policy advocacy, research, on-the-ground implementation; knowledge resources; pilot projects; scalable business models.

State-Specific Initiatives

• Maharashtra (Mukhyamantri Saur Krushi Vahini Yojana 2.0): 16,000 MW solar projects across ~35,000 acres of government and private land.
• Gujarat (Kisan Suryoday Yojana): Daytime power supply up to 16 hours daily (5:00 AM-9:00 PM) through phased solar and non-conventional generation.
• Karnataka (Surya Raitha Scheme): Solar-powered irrigation pumps; farmers earn from surplus electricity.

Challenges

• Capital Costs: Elevated structures; installation.
• Crop Selection: Not all crops suitable; shade tolerance varies.
• Maintenance: Panel cleaning; farming operations around structures.
• Policy Fragmentation: State-specific schemes; need for national framework.
• Land Tenure: Small landholdings; aggregation challenges.
• Awareness: Limited among farmers.

Way Forward

• National Policy: Dedicated agrivoltaics policy; incentives; standards.
• Research: Crop-specific designs; shade-tolerant varieties.
• Financing: Subsidies; low-interest loans; PPP models.
• Demonstration: Expand pilot projects; farmer field schools.
• Integration: Link with PM-KUSUM, PM Surya Ghar, FPOs.
• Monitoring: Track outcomes—energy generation, crop yields, farmer income.

Conclusion

Agrivoltaics can enhance farm incomes and land-use efficiency by combining agriculture with solar power generation, while conserving water and strengthening rural livelihoods. With an estimated potential of 3,000–14,000 GW, initiatives such as PM-KUSUM and state schemes offer significant opportunities. Locally suitable designs, scientific research and farmer participation are essential to balance food production with clean energy goals.

Practice Question

1. Agrivoltaics offers India an opportunity to strengthen agricultural livelihoods while advancing environmental sustainability, with potential estimated between 3,000 GW and 14,000 GW. Critically examine the opportunities, initiatives, and challenges in promoting agrivoltaics in India. (250 words, 15 marks)

GS III – Economy / GS I – Society
Employment, Poverty Reduction, and Structural Transformation

Introduction

India has achieved significant poverty reduction, with extreme poverty falling to 2.6% in 2023 and poverty at the $4.2/day line declining from 57.7% to 16.1%. However, the rise in labour force participation (59% in 2025) has not translated into enough productive jobs, as many women remain engaged in low-paying agricultural and self-employment activities.

The Employment Structure Problem

Agriculture’s Disproportionate Share

• India: ~43% of workforce in agriculture.
• China: 21.68% (World Bank).
• Vietnam: 25% (World Bank).
• Implication: Less productive farm sector employs a large share.

Informal Non-Farm Sector

• Informality: Roughly three-fourths of non-farm workers in informal enterprises—low productivity.
• Contrast: Unlike other Asian countries that moved up the income ladder, manufacturing in India hasn’t absorbed millions of low- and unskilled workers.
• Instead: Employment has expanded in less productive, low-end services.

Regional Concentration of Poverty

• North India: 57% of the poor are found in the “belt stretching from Uttar Pradesh to West Bengal” (World Bank).
• Characteristics: Per capita incomes lower than national average; fewer job opportunities.
• Migration: To high-income regions as a channel for greater access to non-farm employment.

Why This Matters

Moving Up the Income Ladder

• From Lower-Middle to Upper-Middle to High Income: Requires shifting workforce from low to high productivity jobs.
• Biggest Development Challenge: Structural transformation—from farm to non-farm; from informal to formal; from low-end services to manufacturing and high-value services.

Mass Prosperity

• Not Just Poverty Reduction: Need productive, better-paying jobs.
• Demographic Dividend: 450 million youth aged 18-35; need quality employment.

Way Forward

Manufacturing as an Engine

• Labour-Intensive Sectors: Textiles, leather, footwear, food processing, electronics assembly.
• MSME Clusters: Specialised clusters with shared infrastructure.
• Bigger Factories: Incentivise growth of larger factories (>100 workers) with higher productivity and wages.
• PLI and Industrial Policy: Scale up; deepen value addition.

Formalisation

• Ease of Doing Business: Simplify compliance.
• Credit Access: Affordable credit for MSMEs.
• Social Security: Extend to informal workers, gig workers.

Skilling and Education

• Future-Ready Skills: AI, digital, technical.
• Vocational Training: Expand ITIs, PM-SETU.
• Alignment: Education with industry needs.

Regional Balance

• North India Focus: Create jobs in UP, Bihar, Jharkhand, West Bengal.
• Industrial Corridors: Develop infrastructure; attract investment.
• Migration Support: Portable welfare benefits; safe transport.

Women’s Participation

• Affordable Childcare: Safe transport; flexible work.
• Financial Inclusion: Credit; market access.
• Skill Development: Emerging sectors.

Challenges

• Agriculture Overhang: 43% workforce; low productivity.
• Informality: Three-fourths of non-farm workers.
• Manufacturing Stagnation: Not absorbing low-skilled workers.
• Regional Disparity: 57% of poor in north India belt.

Way Forward

• Structural Transformation: Farm to non-farm; informal to formal.
• Manufacturing Push: Labour-intensive sectors; MSME clusters.
• Regional Focus: North India; industrial corridors.
• Skilling: Future-ready; vocational.
• Women’s Employment: Childcare; safety; flexibility.

Conclusion

Despite significant poverty reduction, India faces a major challenge in creating productive, better-paying jobs. High agricultural dependence, informal employment, weak manufacturing absorption and regional disparities constrain income growth. Strengthening labour-intensive manufacturing, formalisation, skilling and women’s workforce participation is essential for transitioning towards a high-income economy.

Practice Question

1. India has made remarkable progress in poverty reduction, but the lack of more productive, better-paying non-farm employment remains an obstacle to mass prosperity. Examine the structural challenges of India’s employment landscape and suggest measures for shifting the workforce to high-productivity jobs. (250 words, 15 marks)
