Territorial designs and international politics: the diverging constitution of space and boundaries. Territory, Politics, Governance. The debate about the role and direction of territory and territorialityespecially with respect to the politically and socially constructed nature of territoryhas been evident within political geography and political science, as well as in other disciplines, for some time. Interdisciplinary interaction over the study of territory, however, has so far been less than impressive. Aiming to enhance our understanding of the place of territory in international relations, broadly defined, and to bridge disciplinary divides, this paper introduces the concept of 'territorial designs'. Territorial designs pertain to the delineation of the external boundaries, to the constitution of the society within these boundaries, and to the interaction between delineation and constitution. It is a process by which elites, in interaction with their own society and their external environment, intentionally and systematically constitute and institutionalize territoriality, and hence also territory. Territorial designs framework, as the papers in this volume collectively highlight, sheds a light on four key areas: the strategic logic and interaction behind different territorial systems; the unintended consequences of such designs; the tensions between regional/ local territorial arrangements and global ones; and the roles that technology and knowledge play in the emergence of different forms of territoriality.
