The world’s oceans play a vital role in everyday life, from climate regulation to food provision, and are widely recognized as a global commons. But they also face daunting challenges in the form of climate change, population growth, escalating pollution, and rapidly evolving technologies that speed the reach and pace of resource extractions. Common Currents: Examining How We Manage the Ocean Commons calls upon experts in international ocean law, policy, and science to explore the question to what extent—and to what effect—we currently manage the oceans as a global commons. This volume captures some key issues, questions, and lessons, to help enhance understanding of current practices and opportunities to grow collaborative management efforts.
