BlueLightS aims at strengthening the skills and competencies of European children and youth to deliver “blue” (river and seas) resilience and sustainability. We will do so by supporting exciting co-built blue challenge projects in schools; facilitating a conversation at different scales between the “blue” and education communities; and, experimenting adaptions in education systems that raise attention given to rivers and seas. It is a challenging project but inspiring and essential for the long-term success of the EU Mission ‘Restore our ocean and waters by 2030’.
