Abstract：Water and food security have drawn long-lasting attention from countries around the world and relevant international organizations.Due to population growth,limitations in cultivated land conditions,constraints on water resources,and the impact of climate change,food security issues need to be addressed through comprehensive measures.These include the continuous improvement and upgrading of existing irrigation and drainage systems,the development of new irrigation and drainage projects,the application of advanced management technologies and tools,and the reform of management systems and mechanisms.Irrigation and drainage systems are large-scale engineering projects that involve agricultural production,ecological processes,and water resource cycling,with increasing attention being paid to their impact on the ecological environment.When emphasizing agricultural water conservation,attention should be given to the scale effectiveness of water-saving practices.While improving the utilization rate of irrigation water,overall consideration should be given to the water cycling process within the irrigation and drainage system,overall water use efficiency and benefits,and the impact on the ecological environment.This study summarizes international advanced technologies and experiences in managing agricultural water use to safeguard water and food security,including the current status and trends of irrigation and drainage development,challenges,strategies,innovations,as well as water-saving concepts,technologies,and measures based on evapotranspiration management.
