Irrigation management is essential for addressing global food security challenges under changing climate. This review discusses the integration of advanced irrigation technologies and their roles in enhancing water use efficiency and managing energy demands within agricultural systems. High-efficiency irrigation systems, such as drip and sprinkler systems, have significant potential to reduce water use and increase crop yields. However, their adoption varies worldwide, and the efficiency of existing irrigation practices often remains inadequate, resulting in substantial water losses due to outdated management practices. Emerging technologies and innovative irrigation strategies, including precision agriculture and advanced crop models, provide promising pathways for improving irrigation efficiency. Nonetheless, the widespread integration of these technologies is hindered by high costs, the need for technical expertise, and challenges in adapting existing agricultural systems to new methodologies. Irrigation systems can have substantial energy requirements, particularly those dependent on groundwater. The exploration of the water-environment-energy-food (WEEF) nexus illustrates the importance of a balanced approach to resource management, which is crucial for achieving sustainable agricultural outcomes. Future research should include lowering barriers to technology adoption, enhancing data utilization for precision irrigation, promoting integrated management strategies within the WEEF framework, and strengthening policy support for sustainable practices. This review proposes a multidisciplinary approach to irrigation management that includes technological innovation, strategic policy development, and global cooperation to secure sustainable agricultural practices and ensure global food supply resilience in the face of climate change.
灌溉管理对于应对气候变化下的全球粮食安全挑战至关重要。本综述讨论了先进灌溉技术的整合及其在提高农业系统用水效率和管理能源需求方面的作用。高效灌溉系统,如滴灌和喷灌系统,具有显著减少用水量和提高作物产量的潜力。然而,它们在全球范围内的采用情况各不相同,并且现有灌溉实践的效率往往仍然不足,导致由于过时的管理实践而造成大量水资源损失。新兴技术和创新灌溉策略,包括精准农业和先进作物模型,为提高灌溉效率提供了有前景的途径。然而,这些技术的广泛整合受到高成本、技术专业知识的需求以及现有农业系统适应新方法的挑战的阻碍。灌溉系统可能需要大量的能源,特别是那些依赖地下水的系统。水-环境-能源-粮食(WEEF)关系的探索说明了资源管理中平衡方法的重要性,这对于实现可持续农业成果至关重要。未来的研究应包括降低技术采用的障碍,增强用于精准灌溉的数据利用,在 WEEF 框架内促进综合管理策略,并加强可持续实践的政策支持。本综述提出了一种灌溉管理的多学科方法,包括技术创新、战略政策制定和全球合作,以确保可持续的农业实践,并确保在气候变化面前全球粮食供应的弹性。
