This thesis makes a critical examination of the concept ‘environmental security’. It explores in depth, and in a manner consistent with critical theory, what has and has not been considered under the rubric of environmental security. In so doing, this thesis develops an account of environmental security informed by concerns for human security and positive peace. The implications of this for politics, policy and governance are also considered. A critical examination of environmental security is timely. The concept has become increasingly popular since the end of the cold war, but the exact meaning of the term is by no means clear. Environmental security is now being used to inform policy. The concept of environmental security is contested between political Realist/ nation-centred approaches and human and ecologically centred approaches. This thesis’ critical examination nds that there are considerable limitations in the political Realist/nation-centred approaches, and its reformulation of the concept draws on the human security approach and is informed by ecological principles. This reformulation offers a more robust environmental security concept which can better contest the meaning and practice of environmental security, and which provides a new perspective on environmental problems and policy.
