Climate change poses challenges world over, but Africa is disproportionately affected by its adverse effects, in particular, displacement. Children are a vulnerable group whose socio-economic rights are guaranteed under the African human rights system, which is defined by a set of human rights instruments and monitoring bodies. However, while social economic rights of the child can be affected by displacement linked to climate change, there has been a rare academic discussion on its extraterritorial link as possible cause and consideration in addressing the problem. This chapter articulates the extraterritorial link of climate change to displacement and socio-economic rights of the child under key instruments of the African human rights system. It then explores how extraterritorial obligations (ETOs) may help in addressing the adverse threats of climate change displacement on the socio-economic rights of the child under the African human rights system.
