India's irrigation system is crucial for its agriculture, which employs nearly 50% of the workforce and contributes significantly to the economy. However, the system faces several challenges that impact the sustainability, efficiency, and productivity of irrigation. Here are the major challenges and measures taken by the government to manage irrigation efficiently.

Major Challenges Faced by the Indian Irrigation System

1. Inefficient Water Use:

• Flood Irrigation Dominance: The majority of Indian farmers use traditional flood irrigation methods, which lead to significant water wastage through seepage and evaporation.
• Over-Irrigation: Crops like rice and sugarcane are often over-irrigated, leading to waterlogging, soil degradation, and declining yields.

2. Over-Dependence on Groundwater:

• Groundwater is a critical resource for irrigation in India, but excessive and unsustainable extraction has led to alarming depletion levels, especially in states like Punjab, Haryana, and Uttar Pradesh. Nearly 89% of groundwater extracted in India is used for irrigation, contributing to declining water tables.

3. Canal System Inefficiencies:

• Canals and surface irrigation systems are often poorly maintained, leading to significant water losses due to seepage and leakages. The efficiency of canal irrigation is estimated to be less than 40% due to outdated infrastructure and poor management.

4. Unequal Water Distribution:

• There is an imbalance in irrigation facilities, with states like Punjab, Haryana, and Western Uttar Pradesh having better irrigation coverage, while eastern states like Bihar, Jharkhand, and Assam remain largely rain-fed, resulting in unequal agricultural productivity.

5. Poor Management and Fragmentation:

• The irrigation system is often poorly managed at the local level. Water User Associations (WUAs) are often ineffective, and there is limited participation of farmers in the planning and management of irrigation systems, leading to suboptimal water allocation.

6. Climate Change:

• Variability in rainfall patterns due to climate change, increasing frequency of droughts, and extreme weather events are exacerbating water scarcity, thereby affecting irrigation. Rain-fed agriculture, which depends on monsoon rains, faces greater risks due to unpredictable weather conditions.

7. Energy-Water Nexus:

• Farmers often use free or subsidized electricity to pump groundwater, encouraging over-extraction. This creates a vicious cycle of water wastage and energy inefficiency, as well as putting pressure on the energy infrastructure.

8. Siltation and Reservoir Capacity:

• Siltation of canals and reservoirs reduces their water storage capacity, especially in major irrigation projects. This affects the timely availability of water during critical periods of crop growth.

9. Fragmented Land Holdings:

• India’s small and fragmented land holdings make it difficult to implement large-scale, efficient irrigation systems like sprinkler or drip irrigation. These systems require investment and infrastructure that are often out of reach for small farmers.
