E09: Nadège Legroux - Marine conservation on the High Seas: Beyond the rule of any one nation

You might have heard of the UN “30 by 30” pledge in the media, which aims at protecting 30% of the earth’s biosphere by 2030. A goal that applies to biodiversity both on land and sea. This goal is highly ambitious, and is particularly difficult to implement on the High Seas - vast areas of the sea owned by no one and hence beyond the jurisdiction of any one nation. Who decides how and where to protect these areas? In today’s conversation with geographer and social scientist Nadège Legroux, we try to shed some light on these questions.

Nadège Legroux is a PhD candidate at the University of Paul Valéry Montpellier III, where she is working on her pluridisciplinary thesis on marine conservation between the French Agency for Development and the Environmental Humanities Laboratory (UMR SENS, Montpellier). Her research focuses on the Costa Rica Thermal Dome, an offshore phenomenon that drives marine biodiversity in geographically fluid ways.
