As climate change reshapes our oceans, fish populations are shifting across borders and into new territories, creating ripple effects for food security, livelihoods, and international relations. These changes are intensifying pressure on governments and coastal communities—and, in some cases, fueling tension and conflict at sea. In this episode of People Places Planet, host Sebastian Duque Rios speaks with Johan Bergenas, Senior Vice President for Oceans at the World Wildlife Fund-US, and Sofia O’Connor, Director of the Environmental Law Institute’s Ocean Program, about the complex links between marine conservation, illegal, unreported, and unregulated (IUU) fishing, and international security.

Together, they explore how climate-driven migration of fish stocks can trigger disputes between nations, how data and transparency tools like WWF’s Oceans Futures platform can help policymakers anticipate and prevent those conflicts, and how legal frameworks can promote cooperation rather than conflict on the high seas.
