Climate change affects the oceans on various levels - as an eco-system, as a storage for CO2, as a source of life, as a threat to coastal communities. For this reason, the UN sustainability goal 14 focuses on the protection of life at sea. The authors of this volume explore the transformative potential of co-creative processes in environmental and climate law, looking at rights of the sea, and on sea. The innovative approach of co-creation emphasises the integration of diverse forms of knowledge, encompassing scientific, indigenous, and local expertise to foster more inclusive and effective governance strategies for climate change and marine conservation, including sustainable fisheries, human rights protection and climate change adaptation. Based on a co-creation methodology that transcends disciplinary boundaries and enhances participatory approaches, this volume offers perspectives on ocean protection from national, regional and international law.
