Introduction
Water scarcity is a pressing issue in India, where the country has 18% of the world’s population but only 4% of its freshwater resources. Agriculture is the largest consumer of this limited water supply, emphasizing the need for efficient irrigation methods. Micro-irrigation, which includes techniques like drip and sprinkler irrigation, offers a promising solution to this challenge.

Benefits of Micro-Irrigation
- Reduction in Water Consumption
- Fact: Micro-irrigation can reduce agricultural water demand by 30-50% by delivering water directly to the root zone, minimizing losses through conveyance, runoff, and evaporation.
- Source: National Mission for Sustainable Agriculture.
- Decreased Dependence on Groundwater
- Fact: This method is particularly effective in dryland farming areas where groundwater aquifers are depleting. It significantly lowers electricity consumption, as less water needs to be pumped.
- Source: Ministry of Agriculture and Farmers’ Welfare.
- Sustainability
- Fact: Micro-irrigation can replace flood irrigation, which causes ecological issues like groundwater pollution and salinity. Localized application helps prevent nutrient leaching, preserving soil health.
- Source: Indian Council of Agricultural Research (ICAR).
- Scalability
- Fact: Currently, less than 50% of agricultural land is irrigated, with over 80% of farmers being smallholders. Micro-irrigation can reduce dependency on monsoons and enhance resilience against drought.

Limitations of Micro-Irrigation
- Affordability Challenges
- The initial investment for micro-irrigation systems can be prohibitive for small and marginal farmers, limiting widespread adoption.
- Maintenance Costs
- Regular maintenance of tubes and sprinklers can be burdensome for small farmers, given the small size of their landholdings.
- Crop Choices
- Micro-irrigation may not alleviate water stress caused by poor agro-climatic choices, such as the cultivation of water-intensive crops like sugarcane and paddy in regions where water is already scarce.
Conclusion
Micro-irrigation has significant potential to alleviate India’s water crisis, especially in water-scarce regions. However, it should be part of a broader strategy that includes water conservation, improved water storage, and a shift in cropping patterns to maximize its effectiveness.

Promote growing of water-efficient and drought-tolerant crops.
illage should apply climate-smart agriculture practice.
Cover cropping, no-till farming, and crop rotation improve soil quality, increase water retention, and lower erosion risk.
Trees and shrubs are combined into agroforestry systems that enhance soil fertility together with farming systems that provide shade and boost biodiversity.
Developers and advocates introduce and promote crop varieties tolerant of heat, drought, and other environmental pressures.
Advances in technology
Data-driven decision making, water and other resources management, crop health maintenance, and the use of GPS, drones, and sensors together define precision farming.
Blockchain technology increases traceability and openness in the supply chain. The farmers also have more access to the markets.
Irrigating and processing solar and wind energy by the farmers helps use renewable energy.
