Practice MCQs
Kailash Arun Nagare’s suicide (2025) highlights the irrigation crisis and unequal water access in India.
India has the highest global water usage in agriculture, but inequity in irrigation access is stark.
Over 80% of India’s water withdrawal goes to agriculture, yet distribution is skewed.
Groundwater exploitation is rising, with 17% of blocks ‘over-exploited’.
Marginalised groups, especially women, bear the brunt of water insecurity and resource decline.
Water productivity (IWP) in key agricultural states like Punjab and Tamil Nadu is poor despite high crop yields.
Irrigation inefficiencies contribute to 8-11% of India’s GHG emissions.
Detailed Insights:
The expansion of irrigation has been spatially unequal, concentrated in water-intensive crops in arid zones.
India uses 688 BCM annually for farm irrigation — the highest globally.
According to Nature Water (2024), India’s unsustainable irrigation expansion (2000–2015) was responsible for 36% of global overuse.
Misaligned cropping patterns (e.g., water-intensive rice, sugarcane in dry zones) worsen water stress and emissions.
Groundwater irrigation, increasingly used due to failing canal systems, is causing aquifer depletion and energy inefficiency.
Policies have reinforced regional inequalities, as better-governed states or wealthier farmers access water more easily.
Energy subsidies promote excessive pumping, with Punjab and Tamil Nadu showing lowest irrigation efficiency despite high productivity.
Scientific/Technical Concepts Involved:
Irrigation Water Productivity (IWP): Yield of crop per unit of irrigation water applied.
GHG emissions from irrigation: Result from energy used in groundwater extraction and rice flooding.
Micro-irrigation: Includes drip and sprinkler systems, promoting water-use efficiency.
Significance:
Water scarcity in India is not just physical but economic and governance-driven, leading to inequitable access.
Marginalised farmers face systemic exclusion, further deepened by climate impacts on water tables.
Future strategies must focus on:
Water-saving irrigation technologies
Improved crop-water alignment
Participatory, decentralised irrigation governance
Solar irrigation and rainwater harvesting can provide sustainable alternatives but must be regulated to prevent overuse.
Mains Mock Question:
Irrigation inefficiency in India is as much a governance issue as it is a technical one. Discuss the multifaceted nature of India’s irrigation crisis and suggest sustainable solutions to ensure equitable water distribution in agriculture.
