Special Issue Information

Dear Colleagues,

Agricultural development has placed increasingly stringent demands on efficient water use. Water-saving irrigation has become a crucial pathway for ensuring food security, improving water use efficiency, and promoting the green transformation of agriculture. This Special Issue will focus on theoretical innovations, engineering applications, and comprehensive benefit assessments of water-saving irrigation technologies in agricultural development. It aims to establish a multidisciplinary platform for academic exchange and to foster the coordinated advancement of irrigation equipment, intelligent control, crop water requirement management, and regional water resource allocation. We welcome submissions addressing topics such as sprinkler irrigation, drip irrigation, micro-irrigation, precision irrigation, digital twins and smart irrigation districts, integrated water and fertilizer management, unconventional water use, economic and ecological benefit evaluation of water-saving irrigation, and irrigation scheduling optimization, with the goal of providing scientific support and practical solutions for sustainable agricultural development.

Under the dual constraints of global food security and ecological protection, conventional agriculture is hampered by low resource efficiency and sluggish environmental response. Crop digital twin technology establishes a dynamic virtual reality system that integrates crops, environment, and water to enable real-time interaction and optimization. Based on the existing literature, this paper reviews the concept, architecture, and core modules of this technology and summarizes its applications in precision irrigation and crop monitoring. There are three major bottlenecks that persist, including limited high-frequency multi-source sensing and spatiotemporal fusion, insufficient parameter calibration and dynamic updating, and weak cross-scale integration from plant to watershed. Water is increasingly recognized as the key constraint and control variable and acting as both the central physiological driver of crop growth and the mass-flow link that connects the soil–plant–atmosphere continuum. The spatiotemporal dynamics of crop water deficit, compensatory root water uptake, evapotranspiration feedback, and the hydraulic behavior of irrigation-district canal systems constitute the core hydrological processes that must be simulated within the digital twin. Synchronizing crop water demand, soil moisture dynamics, atmospheric evapotranspiration, and irrigation scheduling within a unified spatiotemporal framework establishes a complete sensing, diagnosis, prediction and regulation technical chain. This chain offers a core pathway for alleviating agricultural water scarcity, improving irrigation efficiency, and ensuring food security. Full article
