The concept of human security has emerged as an essential paradigm for understanding global vulnerabilities as part of a shift that goes beyond traditional security concerns. According to this paradigm, the main focus of security should be human beings rather than political entities such as states and proposes a multidisciplinary understanding of security covering many fields, such as international relations, strategic studies, human rights and development studies.
The scope of global human security could be expanded to include not only traditional political and military security but also personal, community, economic, environmental, food and health security. Governments cannot feel secure by only continuing to build up their military arsenals but by deterring other military powers from attacking the state. This requires investing in other fields as well.
In today’s globalized and interconnected world, it is almost impossible for any state to isolate itself from the rest of the world by constructing physical walls. All states will continue to be influenced by developments in other parts of the world. For instance, the whole world is influenced by state failures and civil wars in the Middle East. Various waves of refugees have significantly changed the medium of politics across European countries. New refugee influxes have led to an increase in nationalism and xenophobia.
