Agroecology is often considered as the ultimate and most comprehensive solution to the many challenges of the agricultural and food system, also referred to as the agri-food system. This review investigates to what extent agroecology can become the mainstream model for transforming agriculture toward more sustainable and resilient agri-food systems within the given economic and political context. We find that enhancing agroecology will require a fully integrated multiscale systems approach from farm to region to globe. The approach must consider relevant processes and relationships, actors and stakeholders as well as drivers, sustainability indicators, and the respective assessment methods across all scales. Giving specific attention to drivers related to economy, technology, and policy we point out that agroecology needs to be economically viable for farmers and other food system actors. In particular, new and emerging technologies related to digitalization and breeding should be given more consideration in agroecological transformation. We stress the need for an analytical and operational framework and adequate multiscale policy design and suggest six areas of needed attention to support the large-scale adoption of agroecology.

可持续农业和粮食系统的农业生态学：从本地解决方案到大规模采用

农业生态学通常被认为是解决农业和粮食系统（也称为农业食品系统）众多挑战的最终和最全面的解决方案。本综述调查了生态农业在多大程度上可以成为在特定经济和政治背景下将农业转变为更可持续和更有弹性的农业食品系统的主流模式。我们发现，加强农业生态需要从农场到地区再到全球的全面综合的多尺度系统方法。该方法必须考虑相关流程和关系、参与者和利益相关者以及驱动因素、可持续性指标以及所有规模的相应评估方法。我们特别关注与经济、技术和政策相关的驱动因素，指出生态农业对于农民和其他粮食系统参与者来说需要在经济上可行。特别是农业生态转型应更多考虑数字化和育种相关的新兴技术。我们强调需要一个分析和操作框架以及适当的多尺度政策设计，并提出了支持大规模采用生态农业所需关注的六个领域。
