This study aims to investigate the recent international efforts to explore and develop a more coherent approach to increasing protection and assistance needs of internally displaced persons. During the past few years, the world has witnessed acute humanitarian emergencies which resulted in a growing scale of human suffering. These have been mostly triggered by internal conflicts and resulted in a growing number of internally displaced persons. The international responses to the crises of human displacement have been ad hoc and inadequate. in this study, the need for international protection and assistance to internally displaced persons is considered. Then the international law standards in order to meet the protection and assistance needs of internally displaced persons, tlie international instituí ional mechanisms to respond to the crises of intemal displacement and the longer-term strategies of prevention are evaluated.
