This chapter provides a chronological and thematic account of the work carried out in the UK, reflecting on the lessons these experiences bring to sustainability transformations and some of the concepts covered in the earlier chapters. It describes the identification and framing of the sustainability challenge (a sustainable agri-food system in Brighton and Hove), the theoretical approach adopted and the way various methods (e.g. participatory continuum methods such as Evaluation H) were applied. The chapter outlines key moments in the transformation laboratory (T-Lab) process and the lessons that were learnt as a result. Learning from innovative examples from elsewhere in the UK and the importance of strategic alliances are highlighted. The role of the researchers and other stakeholders in reframing the role of the Brighton and Hove Downland Estate (which became the focus of the work) is discussed in depth, and the implications for new pathways are explored.
