In the first episode of Gen sea for 2026, hosts Gilbers and Joelle welcome sociologist José Luis Fournier to explore why ocean conservation cannot succeed without the involvement of people. From marine protected areas and the global 30×30 goal to illegal fishing and community co-governance, this episode explores how the social sciences inform effective ocean protection. Drawing on examples from Costa Rica and the Mediterranean, the conversation reveals why "paper MPas" fail, and how inclusive, participatory management can help the ocean thrive.
