Samata IAS Academy | Samata Mains Answer Writing
Date: 1 November 2026
Practice Set: 002
Examination: UPSC Civil Services Main Examination
Paper: General Studies Paper III
Topic: Major Crops and Cropping Patterns; Irrigation and Irrigation Systems; Water-use Efficiency
Introduction
Indian agriculture faces growing challenges arising from groundwater depletion, inefficient irrigation practices, increasing water demand and climate variability.
Improving water-use efficiency has therefore become an important component of agricultural sustainability. Micro-irrigation systems, particularly drip and sprinkler irrigation, offer significant opportunities to conserve water and improve agricultural productivity.
Today’s exercise examines the role of micro-irrigation in addressing India’s agricultural water challenges.

Way Forward (35–40 words)
Suggest targeted subsidies, farmer training, collective infrastructure and integration with watershed development.
Conclusion (20–25 words)
Emphasise sustainable water management and climate-resilient agriculture.
Section IV: Model Answer
Water-use efficiency is critical for Indian agriculture due to groundwater depletion, growing irrigation demand and increasing climate variability. Micro-irrigation offers an important pathway towards sustainable agricultural production.
Role of micro-irrigation:
- Water conservation: Drip and sprinkler systems reduce conveyance and application losses compared with conventional surface irrigation.
- Improved productivity: Efficient water delivery supports better crop growth and can improve water productivity.
- Fertigation: Drip systems facilitate the application of fertilisers along with irrigation water, improving nutrient-use efficiency.
- Crop diversification: They can support horticulture, vegetables and other high-value crops, particularly in water-stressed regions.
- Energy efficiency: Reduced water requirements can lower pumping needs, subject to system design and local conditions.
However, adoption faces several constraints:
- High initial investment: Installation costs discourage small and marginal farmers.
- Fragmented landholdings: Small plots make investment and maintenance less economical.
- Technical limitations: Clogging, inadequate maintenance and insufficient technical knowledge affect performance.
- Institutional constraints: Limited access to credit, uneven subsidy delivery and inadequate extension services restrict adoption.
Way Forward:
The government should strengthen the Per Drop More Crop component of the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY), promote farmer collectives, provide affordable credit, improve extension services and integrate micro-irrigation with watershed development and rainwater harvesting.
Thus, micro-irrigation, supported by appropriate institutions and crop planning, can improve water-use efficiency and strengthen India’s transition towards climate-resilient agriculture.
Section V: Value Addition for Mains
1. Types of micro-irrigation
| Drip irrigation | Sprinkler irrigation |
|---|---|
| Water is delivered near the plant root zone | Water is distributed through sprinklers in the form of droplets |
| Suitable for orchards, vegetables and many row crops | Suitable for many field crops and uneven terrain |
| Reduces evaporation and runoff when properly designed | Can reduce surface runoff compared with conventional flooding |
| Supports fertigation | Can be used for applying water-soluble nutrients in suitable systems |
2. Important government initiatives
A. Pradhan Mantri Krishi Sinchayee Yojana (PMKSY)
Launched in 2015, PMKSY aims to expand irrigation coverage and improve water-use efficiency.
Its guiding approach is commonly expressed through:
- Har Khet Ko Pani.
- More crop per drop.
- Water conservation and management.
B. Per Drop More Crop
The programme promotes water-use efficiency through micro-irrigation systems, particularly drip and sprinkler irrigation.
It supports the wider objective of conserving water while improving agricultural productivity.
C. Atal Bhujal Yojana
The scheme focuses on sustainable groundwater management through community participation and demand-side interventions in identified areas.
D. Watershed Development
Watershed-based interventions help improve soil moisture, groundwater recharge and rainwater management, complementing micro-irrigation.
3. Important concepts for value addition
Water-use efficiency: The relationship between the amount of useful water utilised and the total water supplied or withdrawn, depending on the measurement adopted.
Water productivity: Agricultural output or economic value generated per unit of water used.
Fertigation: Application of fertilisers through irrigation systems.
Precision irrigation: Application of water according to crop requirements, soil conditions and local climatic factors.
4. Important analytical dimensions
Candidates can enrich their answers by linking micro-irrigation with:
- Climate change adaptation.
- Sustainable groundwater management.
- Agricultural diversification.
- Doubling farmers’ income objectives.
- Food and nutritional security.
- Efficient use of agricultural inputs.
- Sustainable Development Goal 6 – Clean Water and Sanitation.
- Sustainable Development Goal 2 – Zero Hunger.

Section VII: Critical Perspective
Micro-irrigation should not be considered a universal solution to India’s agricultural water crisis.
Its effectiveness depends on several complementary interventions:
- Crop selection: Water-intensive crops in water-stressed regions require appropriate crop diversification strategies.
- Groundwater regulation: Efficiency improvements must be accompanied by sustainable groundwater extraction.
- Water availability: Micro-irrigation cannot compensate for the absence of a reliable water source.
- Maintenance: Filters, pipes and emitters require periodic maintenance.
- Institutional support: Farmer training, affordable financing and timely subsidy delivery are essential.
An important analytical point is that improved irrigation efficiency does not automatically guarantee reduced basin-level water consumption. Water saved at the farm level may be used to expand irrigated area or cultivate more water-intensive crops. Therefore, water-use efficiency must be accompanied by appropriate water governance.
Section VIII: How to Improve Your Answer
While attempting this question, candidates should:
- Begin with the agricultural water crisis rather than a lengthy description of irrigation.
- Distinguish between drip and sprinkler irrigation.
- Explain both water conservation and productivity dimensions.
- Discuss financial and institutional barriers.
- Mention at least one relevant government programme.
- Provide a practical way forward.
- Avoid claiming that micro-irrigation can eliminate all agricultural water shortages.
Common mistake: Writing only about the technical advantages of drip irrigation without discussing the economic and institutional constraints affecting small and marginal farmers.
Conclusion
Micro-irrigation can significantly contribute to sustainable agriculture by improving water-use efficiency, supporting crop diversification and reducing avoidable irrigation losses. However, its success depends on affordable technology, effective extension services, sustainable groundwater governance and appropriate crop planning. India’s agricultural water strategy must therefore combine technological efficiency with institutional and ecological sustainability.
