that the Copenhagen School fails to consider these factors, an alternative model is proposed in which agent, act, and context embody different levels of securitization analysis which presents a more complex understanding of the link between the agents and the systems. (Balzacq, 2010) The agent-structure perspective, both agents and the structures are “into dynamic of action and change” – on the securitisation process, concerns the mutually agreed process where securitising actors and audience, texts and context-structure are all interconnected and embedded. (Stritzel, 2007) This model argues that the socio-political dimension including all the functions within the securitisation process has interchangeable roles, this model goes on to argue that the socio-linguistic approach, threats are developed by securitising actors through discourse.

Another type of securitisation is environmental securitisation. Buzan’s definition of environmental securitisation is that the “environmental sector of security is about relationships between human activity and the planetary biosphere”. (Buzan et al, 1998) The environment is an interdependent sector in society within which security is framed; this is because of the importance of maintaining the environment in order to ensure the survival of humankind as the environment is considered the “essential support system on which all other human enterprises depend.” (Buzan et al, 1998) Environmental securitisation is seen in a global context because the degradation of the environment means the state, audience and referent object can be interchangeable social construction. In this regard, threat to the environment include global warming, deforestation and desertification; this idea of environmental securitisation clashes with the state-centric position that military issues are the only threat for states. However, securitisation can only intercede in an issue if it is considered a threat where extraordinary powers are required for the issue to be dealt with, thus specific environmental threats are given priority by securitising actors. The issues regarding the ecosystems is not always considered a major threat due to their politicisation (Buzan et al, 1998) because of these issues are not always subject to securitisation, although some states may perceive issues regarding environmental issues as a threat but this do by a referent object in a specific social, political, linguistic structure. (Stritzel, 2007) The vague conceptualisation of the specific re
