In recent decades, paying attention to the subject of Climate Change and its destructive effects on different countries around the world have caused regular activities as holding international conferences, and ratifying some international documents. Developing and non-developed countries have less facilities and infrastructures to protect themselves from climate change effects and are more vulnerable. Moreover, African countries due to their climate conditions are the most vulnerable. Even more, they have the main population of climate refugees. Although an increasing effort in Africa has resulted in more legal protection for victims of climate change especially women as the most volunrable people, and has been appeared in many regional treaties, but inconsistency and denial of responsibilities from developing countries have caused serious challenges for long term legal-protection of environmental refugees and displacements, especially women and children who are the most vulnerable of climate change victims. Since a sufficient protection of these people requires a common concern and responsibility between states, referring to the "common but different responsibility" principle is one of the most important legal pillar for burden sharing of the massive climate – change movements.
