The oceans are increasingly understood as a security space. Does the new maritime security agenda lead to new spatial configurations? This chapter introduces the concept of ‘pragmatic spaces’ to explore spatial configurations produced in responses to maritime security. Four exemplary spaces are discussed: how counter-piracy led to the development of high-risk areas; how maritime security capacity building produced new regions constructed through codes of conduct; how the identification of smuggling routes established new forms of international partnerships; and how maritime domain awareness systems advance new transnational spaces of surveillance.
