Suggest measures to improve water storage and irrigation system to make its judicious use under depleting scenario.
In the face of a depleting water scenario, a paradigm shift from an expansion-based to an efficiency-based approach is crucial for our water storage and irrigation systems. We need a multi-pronged strategy that combines traditional wisdom with modern technology for the judicious use of every drop.
For improving storage, we must move beyond a sole reliance on large dams. The focus should be on creating a network of decentralized storage structures. This includes building check dams, farm ponds, and percolation tanks under programs like the Mahatma Gandhi NREGA. A critical measure is the revival and rejuvenation of traditional water bodies like tanks and step-wells, which have been neglected over time. Furthermore, mandatory rooftop rainwater harvesting in urban areas and incentives for the same in rural areas can significantly augment local water availability.
To enhance the irrigation system, the most impactful measure is the widespread adoption of micro-irrigation. Promoting drip and sprinkler systems through the 'Per Drop, More Crop' component of the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY) can cut water consumption by 30-70%. We must also focus on improving the efficiency of our canal systems by lining them to reduce seepage losses and implementing Command Area Development to ensure water reaches the tail-end farms. Empowering farmers through Water User Associations to manage local irrigation systems promotes a sense of ownership and encourages conservation. Using technology for water budgeting and satellite imagery to assess crop water needs can lead to more precise and judicious water use.
