| Open AccessIntegrating science and the arts to deglobalise climate change adaptation
Setting goals that are context-specific, relevant, and collectively shared is critical in adaptation. As necessary elements in target setting, imaginaries for adaptation and the language connected to them remain vague. Visuals produced through art-science collaborations can be great allies to (de)construct imaginaries and deglobalise discourses of adaptation.
