The development of sustainable agri-food systems requires not only new academic knowledge, but also concrete social and organizational change in practice. This article reflects on the action research process that supported and explored the learning process in an emerging agri-food value chain in the Berlin-Brandenburg region in eastern Germany. The action research study involved value chain actors, academic researchers, and process facilitators in a learning network. By framing the network’s learning and problem solving processes in concepts of organizational learning, lessons were drawn for researchers and value chain developers. The results underline the importance of process facilitation in a learning value chain to create a social space, in which the actors in the value chain can interact and find a common basis for collaboration. In the learning process, facilitators used an iterative design to consistently align learning activities with the needs of practitioners to ensure practical relevance. To establish new practices and partnerships, value chain actors challenged existing routines and developed new ideas and visions, while at the same time improving established practices within their organizations and along the entire value chain.

可持续农业食品系统的发展不仅需要新的学术知识，还需要在实践中进行具体的社会和组织变革。本文反映了支持和探索德国东部柏林 - 勃兰登堡地区新兴农业食品价值链中学习过程的行动研究过程。行动研究涉及学习网络中的价值链参与者、学术研究人员和流程促进者。通过在组织学习的概念中构建网络的学习和问题解决过程，研究人员和价值链开发人员吸取了教训。结果强调了学习价值链中流程促进对创造社会空间的重要性，价值链中的参与者可以在其中互动并找到共同的合作基础。在学习过程中，辅导员使用迭代设计使学习活动始终与从业者的需求保持一致，以确保实际相关性。为了建立新的实践和伙伴关系，价值链参与者挑战现有惯例并开发新的想法和愿景，同时改进其组织内和整个价值链中的既定实践。
