JThe aim of the book Security and the Environment: Securitisation Theory and US Environmental Security Policy is to devise a stronger and even more compelling securitization theory. This book proposes a revision of the Copenhagen School's influential securitisation theory that both allows insights into the intentions of securitising actors and enables the moral evaluation of securitization and desecuritisation in the environmental sector of security. Securitisation theory holds that in international relations, an issue becomes a matter of emergency politics/a security issue not because something constitutes an objective threat to the state or to some other entity, but rather because a powerful securitising actor argues that something constitutes an existential threat to some object that needs to be dealt with immediately if the object is to survive.The idea that security is a self-referential practice is not only the essence of securitisation theory; it is also the secret of the theory's popularity and its explanatory potency. More readily than rival security theories, it allows the security analyst to account for the essentially contested nature of security where one and the same concept may mean entirely different, and even opposing, things. Yet although this is a clear, strong point on the part of securitisation theory, the Copenhagen School's preoccupation with it two major shortcomings. According to Floyd, a Fellow at the Institute for Environmental Security and British Academy Post-Doctoral Fellow at the Department of Politics and International Studies at the University of Warwick, UK, the securitisation analyst studies who can securitise on what issues, under what conditions, and with what effects, whilst questions beyond the practice of security, such as those concerning the intentions of securitising actors (e.g. 'why do actors securitise?'), are ignored.And also, the idea that security is a self-referential practice allows no conceptual room for the theorising of what really is a security issue, nor for what ought to be securitised. Under the Copenhagen School's theoretical framework, the security analyst and the securitising actor are 'functionally distinct' entities with the security analyst in no position to assume the role of the securitising actor at any point of the analysis. This, however, does not mean that the Copenhagen School feels 'obliged to agree' with any given securitisation. On the contrary, the school holds strong views about the value of both securitization and also of desecuritisation. They argue that, in all but a few circumstances, securitisations are morally wrong, whereas desecuritisations are morally right. Notably, they arrive at these conclusions by way of what they take to be the effects or consequences of either action.In the case of securitisation, they take the consequences to be dedemocratisation, depoliticisation, the security dilemma and conflict. In the case of desecuritisation, they expect politicisation, understood as a general opening up of debate. Although it is not the securitization analyst's aim to bring about desecuritisation, the securitisation analyst is potentially able, by providing insights into the effects of securitisation, to reduce both the scale and number of escalations and security dilemmas found in the world. The Copenhagen School anticipates that the securitisation analyst will arrive at the very same conclusions regarding the outcomes of securitisation and desecuritisation.This book, by use of the example of the environmental sector of security, shows that securitisations are not categorically morally wrong, but, rather, that depending on the beneficiary of environmental security policies, securitisation can be morally permissible. …
