No doubt that climate change and global warming are one on the main crucial problems facing the international Community in the 21^st Century. It was since the 1950's when accumulated universal efforts were paid in order to address such severe challenge and its impact on livelihoods, health and well- being of millions of people worldwide, and in particular the poorest and most vulnerable ones. Thus, growing attention has been paid by the academia and several international platforms to social, political, economic and humanitarian consequences of environmental challenges, especially violence and security concerns. Therefore, it is quite important to understand the interchangeable relationship between climate change and armed conflict (or security) in Africa, and how does each of them affect human security of the African peoples and constrain Africa's Agenda of 2063. It's the core aim of this study to shed the light on the environmental disasters as a trigger of armed conflicts in some African areas from a side, and from the other side analyze how the existence of such armed conflicts is threatening human security, including the environmental security, in the aforementioned areas.             By applying the legal methodology, the study covers the following elements: New dimensions of Human Security: the case of Environmental Security. Climate change as an environmental risk threatening Africa. The interchangeable relationship between climate change and armed conflicts in Africa. The African Experience on Combating Climate Change: Opportunities and Challenges.
