During the last decades the links between emerging risks and the security of humans and nature have been the object of considerable research and deliberations. However, it is only recently becoming an important focus of policy making and advocacy. In this contributed volume, it is presumed that the ability – or lack thereof – to make innovative conceptual frameworks, institutional and policy arrangements, and technological advances for managing the current emerging risks, will foster or undermine the environmental security, and consequently determine the future human security. Moreover, taking into account the links between environmental/climate security, human security and sustainability will help frame a new research agenda and potentially develop a broad range of responses to many delicate questions.
