The Platform for Algae Diplomacy (Filip Van Dingenen & Hélène Meyer) is an open initiative created by a variety of sea plants together with artists, activists and critters. The Platform organizes lectures, performances, seaweed cuttings and ceremonial tastings/bathings. Inspired and choreographed by the tidal movements and migration patterns, and guided by the moon phases and its constellation, it pursues an interrelated linguistic embodiment of seaweed rights & seaweed spirits. Through a playful approach the Platform for Algae Diplomacy encourages an openness and ongoing curiosity for learnings and guidance by plants and other-than-human entities. The Platform on Algae Diplomacy acts as a model to identify and promote the needs and urgencies of critical resistance, to expand narratives and support the inclusion & equality of multiple voices. The Platform has realized workshops and exhibitions in a.o. Ireland, Norway, Belgium, France, Morocco and Turkey.
