In Africa, this has been promoted through Regional Economic Communities such as the East African Community (EAC), the Southern African Development Community (SADC) and the Economic Community of the West African States (ECOWAS). Initiatives include the SADC Region Information Infrastructure (SRII), Intelcom II in ECOWAS and the East African Backbone System (EABS) in the EAC. The New Partnership for African Development (NEPAD) and the Programme for Infrastructure Development in Africa (PIDA) have also been active in promoting cross-border interconnection and the importance of leveraging transport corridors and electricity networks for rolling out regional fiber networks.
