Agricultural irrigation induces greenhouse gas emissions directly from soils or indirectly through the use of energy or construction of dams and irrigation infrastructure, while climate change affects irrigation demand, water availability and the greenhouse gas intensity of irrigation energy. Here, we present a scoping review to elaborate on these irrigation-climate linkages by synthesizing knowledge across different fields, emphasizing the growing role climate change may have in driving future irrigation expansion and reinforcing some of the positive feedbacks. This Review underscores the urgent need to promote and adopt sustainable irrigation, especially in regions dominated by strong, positive feedbacks.
农业灌溉直接通过土壤排放温室气体，或通过使用能源、修建水坝和灌溉基础设施间接排放温室气体，而气候变化则影响灌溉需求、水资源可获取性以及灌溉能源的温室气体强度。在这里，我们进行了一次范围界定综述，旨在通过综合不同领域的知识来详细阐述这些灌溉与气候的联系，强调气候变化在推动未来灌溉扩张方面可能发挥的日益重要的作用，并强化某些正反馈效应。本综述强调了迫切需要推广和采用可持续灌溉，特别是在受到强烈正反馈效应主导的地区。
