The progress of globalization has given rise of regionalization all over the world. This article explains the progress of regionalization in African refugee problem area by global and regional institutional change.
In the refugee problem area, there are two types of institution, one is an institution normatively formed for the refugee protection, which is called the international institution for refugees, and the other is an institution type without normative formation.
International institution for refugees consists of the global system and the regional system, which can be called ‘nested’ institutional complex. Interaction between those two systems showed unilateral complement by the regional system. That was why the nested international institution for refugees remained its European centric feature, so that it had little effect in Africa.
On the other hand, since 1990s, the horizontal institutional complex which consists of both international institution for refugees and African regional frameworks such as AU, ECOWAS, SADC and etc, has appeared in African refugee problem area. Such change from the nested to the horizontal was derived from global and regional institutional change.
External factors, such as the end of Cold War and the situation of refugee problem in Africa, had some influences on each institutional change. However, these are insufficient to explain the difference in their process of change.
With the institutionalism theory approach, following conclusions have been led;
International institution for refugees has extended in the way of UNHCR activity. By offering informational and transactional functions, UNHCR had been acquired the spontaneous order, which made UNHCR take initiative in implementation of institution after the end of Cold War.
In Africa, AU has strengthened their existing framework for refugees, on the other hand, ECOWAS and SADC has extended their problem area from economy to politics. Internal factors of AU, such as a firm collective decision making system and transactional functions offered by a secretariat, caused institutional reinforcement. In addition, AU had had an organ specialized for refugees, which has reduced the asset making costs. Internal factors of ECOWAS showed different aspects. Because of the lowness of asset specificity, informational and transactional functions such as a trust building system and a decision making system could be applied from economic to political area. And it is also because refugee problem has both humanitarian and security aspects, institutionalization in security area could be spill over to refugee area. In addition, economic institution and refugee institution have common strategies on management of migration. These influences derived from economic institution can be seen in institutional change in SADC. In addition, SADC has historically had political aspects, which made institution extend to political area easily.
