Economic vs social infrastructure

TypeDefinitionExamples
Economic infrastructureDirectly supports production processTransport, power, communication, banking, irrigation

  • OMT — Operate-Maintain-Transfer.

Examples: GMR Hyderabad Airport, GVK Mumbai Airport, Bangalore Metro, Mumbai-Pune Expressway, Delhi-Mumbai Industrial Corridor. Challenges: bidding disputes, NPA accumulation, public interest disputes (e.g., Delhi Airport private monopoly disputes), renegotiation issues. Kelkar Committee (2015) and Vijay Kelkar Committee on PPP recommended reforms.

National Infrastructure Pipeline

The National Infrastructure Pipeline (NIP), launched 31 December 2019, is a five-year (2020-25) coordinated infrastructure plan with ~7,000 projects worth ₹111 lakh crore — across roads (₹19.6 lakh cr), railways (₹13.7 lakh cr), urban infrastructure (₹16.5 lakh cr), energy (₹24 lakh cr), water + sanitation (₹3.7 lakh cr), digital communications (₹3.2 lakh cr), and social infrastructure (₹13 lakh cr).

NCERT exercise solutions — selected answers

Q1. Explain the term 'infrastructure'.

INFRASTRUCTURE refers to BASIC SUPPORTING FACILITIES and SERVICES that are REQUIRED for the PRODUCTIVE ACTIVITY of an ECONOMY. It includes: (1) ECONOMIC infrastructure — TRANSPORT (roads, railways, ports, airports), POWER, COMMUNICATION (telecom, internet), BANKING and finance, IRRIGATION; (2) SOCIAL infrastructure — HEALTH facilities (hospitals, PHCs), EDUCATION facilities (schools, colleges), HOUSING, SANITATION. INFRASTRUCTURE is also called the 'WHEELS OF DEVELOPMENT' or 'BACKBONE' because: (1) WITHOUT GOOD ROADS, farmers can't sell crops; (2) WITHOUT POWER, factories can't run; (3) WITHOUT INTERNET, services can't be delivered; (4) WITHOUT SCHOOLS, no education; (5) WITHOUT HOSPITALS, no health. INFRASTRUCTURE INVESTMENT has HIGH MULTIPLIER EFFECTS — every ₹1 of infrastructure spend generates ₹2-3 additional economic activity. India's NATIONAL INFRASTRUCTURE PIPELINE (NIP) 2020-25 — ₹111 LAKH CRORE coordinated investment plan covering ~7,000 projects across roads, railways, urban infrastructure, energy, water, digital communications.

Q2. Explain the relevance of infrastructure for economic development.

Infrastructure is RELEVANT for economic development because: (1) PRODUCTIVITY ENHANCEMENT — good roads, power, communications increase productivity across sectors; (2) MARKET ACCESS — farmers can reach mandis, manufacturers can ship to consumers; (3) FACTORY LOCATION — industries locate where infrastructure exists; (4) REDUCES COSTS — efficient infrastructure reduces transport, energy, communication costs; (5) EMPLOYMENT — infrastructure construction itself creates jobs; (6) RURAL-URBAN INTEGRATION — connects villages to cities and global markets; (7) FOREIGN INVESTMENT — infrastructure quality is a key determinant of FDI; (8) URBANISATION supports — water, power, housing, transport for growing cities; (9) HUMAN CAPITAL FORMATION — schools, hospitals enable better human resources; (10) COMPETITIVENESS — Indian exports depend on efficient ports, airports; (11) AGRICULTURAL OUTPUT — irrigation, electrification, roads boost rural economy. EVIDENCE: (1) STATES with better infrastructure (Maharashtra, Gujarat, TN) have higher per capita income; (2) East Asian growth was infrastructure-led; (3) China's growth was preceded by massive infrastructure investment; (4) Indian growth post-2003 partly driven by NHAI, telecom, power expansion. INDIA's NEED: (1) ~$1.5 trillion (₹125 lakh cr) infrastructure investment needed 2024-30 per FICCI estimates; (2) Quality vs quantity — need not just more infrastructure but smarter, greener, climate-resilient.

Q3. Discuss the state of rural infrastructure in India.

RURAL INFRASTRUCTURE in India has improved significantly but still faces gaps. ACHIEVEMENTS: (1) ROADS — PMGSY connected 99%+ of habitations (>500 population) with all-weather roads; ~7 lakh km rural roads built; (2) ELECTRIFICATION — 100% village electrification 2018 (28,000+ unelectrified villages connected under Saubhagya 2017); (3) WATER — Jal Jeevan Mission tap water connection ~75% rural households (vs 17% in 2019); (4) SANITATION — Swachh Bharat 12+ crore toilets; 100% village ODF (Open Defecation Free) declared 2019; (5) TELECOM — BharatNet connecting 2.5 lakh Gram Panchayats; ~60% rural internet penetration; (6) BANKING — PMJDY 51+ crore accounts; Banking correspondents in remote areas; (7) ICDS Anganwadi centres — 13.9 lakh+; (8) Sub-Centres + PHCs serve rural areas. GAPS: (1) ROAD QUALITY — many PMGSY roads needing maintenance; (2) IRRIGATION — only ~50% of net sown area irrigated; (3) ELECTRICITY QUALITY — supply unreliable in many rural areas; voltage fluctuations; (4) COLD STORAGE — Inadequate; ~₹1 lakh crore losses annually; (5) MARKET YARDS — limited; APMC dominated by middlemen; (6) HEALTHCARE — PHC vacancies; CHC specialist shortage 70%; (7) EDUCATION — quality variable; ASER report 30%+ Class 5 children can't read Class 2; (8) HOUSING — PMAY-G aims 2 crore+ houses; (9) Internet — 4G/5G last-mile in remote areas. RURAL INFRASTRUCTURE INVESTMENT remains critical for: poverty reduction, agricultural productivity, demographic dividend, climate resilience.

GAPS: (1) DISCOM losses ~₹1.5 lakh crore; (2) Power theft; (3) Grid stability with renewables; (4) Coal dependence; (5) Air pollution from thermal plants; (6) Inadequate storage. India's energy transition is one of the world's largest — and one of its most consequential for global climate.

Q5. What are the inadequacies of India's health infrastructure?

India's health infrastructure has significant inadequacies: (1) PUBLIC HEALTH SPENDING ~2.1% of GDP — far below WHO recommended 5%+; NHP 2017 target 2.5% by 2025 still unmet; (2) SHORTAGE OF DOCTORS — 1 doctor per 1,400 population (WHO 1:1,000); (3) PSYCHIATRISTS — 0.75 per lakh vs WHO recommended 3; (4) HOSPITAL BEDS — 1.4 per 1,000 population (WHO 3+); India added beds during COVID but still inadequate; (5) PHC VACANCIES — 10% of MBBS positions, 25% nurses, 70%+ CHC specialists; (6) RURAL-URBAN DIVIDE — 70% population in rural areas accesses <10% of psychiatric facilities; (7) OUT-OF-POCKET EXPENDITURE — 47% (vs WHO recommended <15%); (8) MEDICAL EDUCATION — quality variable; ~660 medical colleges (private 56%) but training quality concerns; (9) NCD (Non-Communicable Disease) preparedness inadequate — diabetes, hypertension, cancer rising; (10) MENTAL HEALTH services severely under-developed; only 20% of PHCs offer basic mental health services; (11) AYUSHMAN BHARAT — primary care (Ayushman Arogya Mandir 1.6 lakh) + secondary/tertiary (PMJAY ₹5 lakh cover for 55 crore); but uneven across states; (12) PM-ABHIM (₹64,180 crore 2021-26) addresses critical care, surveillance, BSL labs; implementation progressing. (13) INSURANCE coverage — ~50% population covered by some insurance; gaps in OPD coverage. (14) HEALTH WORKFORCE — total shortage including doctors, nurses, allied health workers ~30 lakh. STRATEGIC RESPONSE: Ayushman Bharat + PM-ABHIM + Mission Karmayogi + NEP 2020 + 5+ years of consistent investment.
