Q.What are the major challenges faced by the Indian irrigation system in recent times? State the measures taken by the government for efficient irrigation management.

Body

1. Major Challenges Faced by the Indian Irrigation System

• Overexploitation of Groundwater: Excessive reliance on tube wells has led to a severe decline in water tables, particularly in intensive agricultural states like Punjab, Haryana, and Rajasthan.
• Inefficient Water Use Practices: Traditional flood irrigation remains widespread, causing massive water wastage. The adoption of modern micro-irrigation techniques (drip and sprinkler) remains low.
• Poor Irrigation Infrastructure: Siltation, leakages, and inadequate maintenance of canals and dams reduce their carrying capacity, while incomplete command area development limits their potential.
• Regional Disparities in Access: Eastern and northeastern states, despite high water availability, have lower access to assured irrigation compared to northwestern states, leading to uneven crop yields.
• Dependence on Monsoon: A significant portion of agriculture still relies on monsoons, leaving crops highly vulnerable to erratic rainfall patterns caused by climate change.
• Salinization of Soils: Poor drainage in canal-irrigated areas leads to waterlogging and soil salinization, rendering fertile land unproductive.
• Fragmented Landholdings: The high proportion of small and marginal farmers makes implementing large-scale irrigation projects and adopting modern micro-irrigation technologies economically challenging.
• Energy-Water Nexus: Highly subsidized or free electricity for agriculture encourages indiscriminate groundwater pumping, worsening water scarcity and straining power grids.

2. Government Measures for Efficient Irrigation Management

• Pradhan Mantri Krishi Sinchayee Yojana (PMKSY): Launched in 2015 with the vision of "Har Khet Ko Pani" (water to every farm), this scheme aims to expand cultivable area under assured irrigation and improve water-use efficiency.
• Per Drop More Crop: A key component of PMKSY that promotes micro-irrigation technologies (drip and sprinkler systems) through financial assistance to farmers, significantly reducing water wastage.
• Command Area Development and Water Management (CADWM): Focuses on bridging the gap between irrigation potential created and utilized, ensuring equitable water distribution to tail-end farmers.
• Atal Bhujal Yojana (Atal Jal): A community-led groundwater management scheme launched in 2019, targeting water-stressed blocks to encourage sustainable water conservation.
• National Mission for Clean Ganga (NMCG): Promotes water-use efficiency and eco-friendly agricultural practices along the Ganga basin to prevent river pollution.
• Revival of Traditional Water Bodies: Encourages the restoration of traditional water harvesting structures like ponds, tanks, and check dams to recharge groundwater tables.
• Jal Shakti Abhiyan: Launched in 2019, this campaign focuses on rainwater harvesting, water conservation, and the renovation of traditional water bodies across water-stressed districts.
• Subsidies for Modern Irrigation: The government provides substantial financial incentives and subsidies to make micro-irrigation equipment affordable for small and marginal farmers.
