Every day, thousands of people die from hunger, homelessness or lack of adequate care. Natural disasters, epidemics, famines, wars and terrorist attacks are five situations that can lead to human beings, who have become refugees, being unable to survive by their own means. These structural ills are at the heart of the concerns of Humanitarian Action, which call upon the International UN, Governmental and Non-Governmental Organisations. The refugee issue is, today, a major concern on the international scene. Africa is one of the regions of the world most affected by the phenomenon of uprooted people. In 2015, there were 3.7 million refugees and 11.4 million internally displaced persons in Africa. These figures were reinforced by the conflict in the Central African Republic in 2013, which forced people to seek refuge in Cameroon and required a humanitarian response. In this context, this research aims to assess the framework and effectiveness of Plan International's humanitarian actions.
