Migration-focused humanitarian crisis management: An analysis in terms of complexity theory

The civil war in Syria, which has been ongoing since 2011, has led to a humanitarian crisis and a migration crisis with the destruction it has caused, and this situation has brought about a multidimensional international intervention. The fact that the Syrian crisis is still unresolved makes it necessary to address this issue from a different perspective. In this context, this thesis aims to understand why the Syrian crisis has turned into a migration movement that is difficult to control from the perspective of the UN, EU and Türkiye. Therefore, the main research question of this thesis is defined as: "What are the effects of the complexity of humanitarian crises and crisis migration caused by the Syrian civil war on migration-focused humanitarian crisis management at the global, regional, and national levels?" The purpose of this study is to examine the concepts of humanitarian crisis and migration from the perspective of complexity theory. While there are many studies on the concepts of humanitarian crisis and migration in the literature, there is no perspective on both concepts, especially in the Turkish literature. This study is important because of its efforts to explain the effects of the Syrian civil war on Türkiye through the lens of complexity ontology and epistemology, focusing on humanitarian crisis and crisis migration. Furthermore, this thesis study, which addresses humanitarian crisis, crisis migration, and migration focused humanitarian crisis management within the framework of complexity theory, argues that humanitarian crises and crisis migration are complex phenomena, that require the evaluation of global migration and humanitarian aid regimes together, and that this coexistence gives rise to the heterarchy of crisis migration.
