By enabling effective, data-driven irrigation techniques in agriculture, digital technologies are revolutionising precision water management. Real-time monitoring of crop water requirements and field variability is made possible by tools like remote sensing, IoT-based soil moisture sensors, and GPS-guided systems. By lowering water waste and increasing water-use efficiency, these technologies facilitate site-specific irrigation. Irrigation scheduling and resource optimisation are further improved by integrating artificial intelligence and decision support systems. Precision water management reduces environmental effects, conserves water resources, and boosts crop productivity. It is essential for resolving water scarcity and guaranteeing sustainable agricultural production in the face of shifting climate conditions.
