Wave Makers is a youth exchange for 20 young people from Denmark and Belgium, addressing ocean health through arts and activism. During the project, we engage with the Danish Limfjord's biodiversity crisis by developing ocean literacy, staying with the trouble, and promoting responsible and creative actions to heal and protect the ocean as a vital resource for current and future generations. Wave Makers is a project built on the ideas of a group of Danish youth, supported by 4 organisations: Nyskaben (DK), UMMK (DK), EMSEA (BE), and VUB (BE). We chose to have two partners per country to increase our support in each country, expand our reach to youth, and bring in diverse and complementary expertise. As such, the project offers an interdisciplinary approach to climate youth work by gathering expertise from participatory arts, youth work, ocean education, and research in arts education. We have identified 4 key objectives: (1) develop ocean literacy, (2) being together, (3) bonding across borders, (4) doing actions. We develop ocean literacy by understanding ecological interconnectedness, foster a sense of togetherness with the sea to combat ecoanxiety, establish relations across country borders and disciplines, and undertake concrete actions through art and hands-on contributions to the ocean. Participants engage in immersive and shared learning experiences near the Limfjord, emphasising sensory engagement and mental health awareness. The initiative aims to create impactful international relationships, addressing the biodiversity crisis by using diverse backgrounds in youth work, arts, and education to make tangible contributions to the sea and raise awareness about its importance. The project is coordinated by Marieke Breyne (Nyskaben) in collaboration with Elvira Crois (VUB). They both take on the role of facilitator. Alongside the 2 facilitators, we have 3 group leaders: Evy Copejans (EMSEA), Kjartan Annesen (UMMK), and Bob Lundgreen (Nyskaben). This amount of professional support responds to the inclusion needs of the group.
