This paper aims at searching an effective approach for emergency management in terms of cognitive relativism. As the main goal of a nation is to protect the lives and properties of the people, the national security must be maintained for preserving their freedom. In this sense, emergency management is the top priority in state governance and prerequisite of policy paradigm. Emergency can be managed in terms of three stages: prevention, preparedness and treatment. In this paper, the writer reviews various approaches for emergency management and focuses on the systems and situational approaches in terms of cognitive relativism. For the whole viewpoint of state governance, emergency management needs to be dealt with as a part of policy process. For this purpose, the writer suggests the structural, procedural, managerial, behavioral, political, social, systems, comparative, and intuitive approaches. Since each approach has its merits and limitations, the writer discusses the usefulness of the situational approach which is to utilize strengths of each approach for synergistic effect. The situational approach in the paper implies that the systems approach is fundamentally relied upon along with partial use of other approaches
