During the course of this research project, the literature review found that Dr. Simon Dalby (2002b) suggests that environmental security concept has evolved in four “stages” that include:
As the debate over environmental security has matured, it has now
benefited from several years of focused research. As a result,
fears of direct “large-scale [nation-state] warfare over renewable
resources” have mostly receded (Dalby 2002b: 95). As this concept
has developed into its third and fourth stages, Dalby (2002b)
identified and summarized the six main “schools” of environmental
security thought, which have been summarized in the table below
(96).
