What are the major challenges faced by Indian irrigation system in recent times? State the measures taken by the government for efficient irrigation management.
Based on 25 evaluated answers to this question on CollectorBabu: here is what aspirants most often missed, the mistakes that cost marks, and a model answer.
What most aspirants missed
- Participatory Irrigation Management through Water User Associations as a governance reform, with examples of successful WUAs
- Canal irrigation efficiency of about 35-40% and the resulting water loss in transit as a major challenge
- IPC vs IPU gap: irrigation potential created is not fully utilised
- Groundwater over-exploitation linked to free power and open access, with CGWB data on over-exploited blocks
- Waterlogging and soil salinity in Punjab and Haryana due to over-irrigation, and regional disparity between states
- PMKSY's Har Khet Ko Pani and More Crop Per Drop components, plus Command Area Development under CADWM
Common mistakes
- Listing challenges without linking each one to a specific government measure, so the answer does not address both parts of the question
- Treating structural features like dependence on monsoon as recent challenges instead of focusing on climate variability and groundwater stress
- Giving generic measures without naming schemes such as PMKSY, PIM, CADWM, Atal Bhujal or PM-KUSUM
- Using unverified statistics or mixing up unrelated schemes such as Jal Jeevan Mission, which is for rural drinking water, with irrigation
What the better answers did
- Naming PMKSY with its components and CADWM as specific measures aimed at canal efficiency and micro-irrigation
- Using regional examples such as Punjab-Haryana waterlogging, groundwater over-exploitation in north-west India, and Cauvery-Krishna disputes
- Explaining the mechanism of each challenge, such as how free power drives groundwater depletion or how IPC-IPU gap arises from poor distribution
- Ending with a concluding line that connects challenges to measures and suggests a balanced supply-and-demand approach
Introduction
Open with a one-line definition of the current state of Indian irrigation, such as the shift from traditional means to modern technologies, while still facing allocation and sustainability issues.
Conclusion
End by linking the main challenges, such as canal losses and groundwater depletion, to measures like PMKSY, PIM and PM-KUSUM so that the answer shows a clear way forward.
Model answer
Indian irrigation has expanded from canals and tubewells to a mix of surface, groundwater and micro-irrigation, yet the gap between irrigation potential created and utilised, along with inefficient water use, keeps the sector under strain. Recent challenges are shaped by groundwater depletion, canal inefficiency, climate variability and governance gaps.
Major challenges
- Canal inefficiency: Conveyance and field-level losses keep canal irrigation efficiency at roughly 35-40%, and poor last-mile connectivity leaves tail-end farmers without water.
- IPC-IPU gap: Large irrigation potential created under major and medium projects remains unutilised due to incomplete distribution networks and poor maintenance.
- Groundwater over-exploitation: Free or subsidised power and open access to tubewells have pushed many blocks into the over-exploited category, notably in Punjab, Haryana, Rajasthan and Gujarat.
- Waterlogging and salinity: Over-irrigation in canal command areas of Punjab and Haryana has raised water tables and salinity, reducing soil productivity.
- Climate variability: Erratic monsoon and longer dry spells make canal-based planning unreliable.
- Inter-state disputes: Cauvery and Krishna water sharing disputes delay projects and reduce basin-level planning.
- Regional disparity: Eastern India, with its lower irrigation coverage, remains underserved compared to the north-west.
Government measures
- PMKSY: Har Khet Ko Pani covers source creation and water-use expansion, while More Crop Per Drop promotes micro-irrigation through drip and sprinkler systems.
- Command Area Development and Water Management (CADWM): Focuses on field channels, warabandi and on-farm development to improve canal efficiency.
- Participatory Irrigation Management: Water User Associations take over distribution and maintenance, improving collection of water charges and accountability.
- Groundwater management: Atal Bhujal Yojana supports community-led groundwater management in water-stressed blocks of seven states.
- Solar pumps: PM-KUSUM promotes solar pumps to reduce subsidised electricity use and diesel dependence.
- Policy framework: The National Water Policy 2012 prioritises efficiency, and the National Water Mission under NAPCC targets a 20% improvement in water-use efficiency.
The way forward lies in pairing supply expansion with demand management, including realistic water pricing, PIM, groundwater regulation and basin-level planning. Linking each challenge to a specific measure will decide whether the irrigation gap actually closes.
