Abstract
The International Organization for Migration (IOM) defines international migration as the movement of persons who leave their country of origin or country of habitual residence to permanently or temporarily to another country (IOM, 2005). Since the emergence of the Westphalian state, migration from one country to another has been primarily governed by sovereign decisions. War, civil war, and conflict; globalisation of economies, values, and aspirations; changing technologies and modes of communication; shifting demographics; increased longevity; increased education levels; urbanisation; and climate change are examples of such factors (Hofmann, Jolivel, Huss, & Ambiaux, 2020). As a result, one of the primary ways in which sovereign nation-states have dealt with irregular migration has been through border enforcement mechanisms. Irregular migration is viewed as an attack on state sovereignty, demanding the state’s ability to exercise control over its spatial and territorial domain into question. Many states have spent vast sums on border security in recent years, including the deployment of immigration officers and border guards, the construction of barriers and border fences, the interdiction of migrants in transit, and resorting to large-scale removals and detention to regulate the inflow of migrants. Security can be classified into two categories like, human or state-centric. This paper is concerned with the human-centric security aspects. By looking at how cross-border migration flows affect national interests, this paper provides a framework for thinking about the relationship between migration and national security.
