This work presents the evolution of the traditional concept of "e;national security"e; as military security to additionally embrace "e;environmental security"e; and then necessarily also "e;social (societal) security"e;, thence to be termed "e;comprehensive human security"e;. It accomplishes this primarily by presenting 11of the author's own benchmark papers published between 1983 and 2010 (additionally providing bibliographic citations to a further 36 of the author's related publications during that period). The work stresses the importance of transfrontier (regional) cooperation, and also recognizes global overpopulationas a key impediment to achieving comprehensive human security.
