Securitisation of international migration is now a widely accepted phenomenon. Human security or insecurity is an important aspect of this broader security concern. International migration raises security issues at different levels because it involves a multitude of agencies that often have conflicting interests. In this conceptual review, main areas and actors of migration associated conflict are discussed. The aim is to explore the possibility of developing a conflict-based model that will facilitate the understanding of contemporary international migration flows and the reasons, mechanisms and dynamics underpinning them. Different stages of migration bring out different sets of conflicting security interests. The concept of environment of insecurity is placed within this multilevel conflict model. This study aims to provide a new understanding of human security and migration nexus from a conflict perspective which is conducive to a comprehensive migration conceptualisation and viable policy solutions.
