Micro-irrigation is increasingly recognized as a key strategy for promoting water-efficient agriculture and enhancing climate resilience. By delivering water directly to the plant root zone, drip and sprinkler systems reduce water loss, improve crop productivity, and help farmers adapt to erratic rainfall and drought conditions. This review examines the role of micro-irrigation in supporting sustainable farming practices, including soil moisture management, nutrient efficiency, and yield stability. It also discusses technological innovations, economic considerations, and policy frameworks that facilitate adoption. Challenges such as high initial costs, maintenance requirements, and knowledge gaps are highlighted, along with potential solutions to expand micro-irrigation use in water-scarce regions.
