“We’re All Swimming in the Same Water” is a performative sound walk along the Hamburg harbor. The project connects water metaphors with migration and climate discourse in both historical and contemporary contexts. Rather than taking a retrospective look at colonial legacies, it focuses on current structures of movement and exclusion. Water serves as both an analytical and poetic figure—as a vessel of memory and a tangible force. The project examines how terms such as “flood” or “wave” shape perceptions by creating a sense of powerlessness, dehumanizing, and obscuring responsibilities. Against this backdrop, migration and climate change are increasingly framed as security risks, shifting the focus toward regulation and perpetuating colonial logics.
