Action education provides an appropriate set of methods for learning about the complexities of farming and food systems. Agroecology provides the framework to organise learning opportunities for students interested in solving challenges in today's world. Our programmes in agroecology concentrate on discovery and learning. Rather than agroecological theory having primary value, we immerse students in practical phenomena at the farming and food system level, and let these phenomena determine what theory is necessary and relevant. Teachers are converted from lecturers to leaders and catalysts in the learning process. In a learning landscape on campus, on farms, and in communities, we find direction by focusing on how students can become agroecologists. Students will have knowledge of farming and food systems, and the skills necessary to handle complexity and change, to link theory to real life situations, to commu-nicate and facilitate in an effective way, and to be auton-omous in their learning. Agroecology and sustainable agriculture are good places for training in these skills. Such skills will be vital for graduates to proactively deal with the challenges of specialisation, high technol-ogy, and use of non-renewable resources in modern society, in the quest for strategy to achieve sustainable development.
