The consequences of climate change poses a serious threat to peace and security on the African continent. It may, for instance, result in competition for and conflict about scarce resources. Potential conflict may be reduced by the capacity to adapt, but there are various constraints on the capacity of African countries. Thus, it is essential to support climate change adaptation. Africa may increase their adaptive capacity through international negotiations, however, African states lack the resources to pursue this goal. The African Union has therefore facilitated the establishment of a common African position on climate change aimed at international climate change negotiations. Accordingly, the primary aim of the article is to discuss the pursuit of the enhancement of adaptive capacity and therefore environmental security of African states through Africa’s common position on climate change.
