This is the first episode in the podcast mini series Global Commons and Their Discontents, a series which aims to present the contributions and discussions from our September 2022 workshop of the same name. In this episode we hear from Dr. Daniel Lambach, a political scientist currently working as a Heisenberg Fellow at the Research Centre Normative Orders at Goethe Universität Frankfurt. Lambach provides a helpful overview of three different global commons domains, the oceans, airspace, and outerspace, as well as the three types of spatial models used in the territorialization process of these domains. He also identifies several territorialization trends and considers what this means for the future of global commons management and use. His recent two publications are about the Functional Territorialization of the High Seas and Technology and the Construction of Oceanic Space: Bathymetry and the Arctic continental shelf dispute.
