At the root of our understanding of territory is the concept of terra-land-a surface of fixed points with stable features that can be calculated, categorised, and controlled. But what of the many spaces on Earth that defy this simplistic characterisation: Oceans in which 'places' are continuously re-formed? Air that can never be fully contained? Watercourses that obtain their value by transcending boundaries? This book examines the politics of these spaces to shed light on the challenges of our increasingly dynamic world. Through a focus on the planet's elements, environments, and edges, the contributors to Territory beyond Terra extend our understanding of territory to the dynamic, contentious spaces of contemporary politics.
