Terms of reference for the second priority medium term project, the Akobo/Pibor transboundary multipurpose development project, prepared as part of the BAS Multi-Purpose Water Resources Development Study. It aims to further the cooperative management of this transboundary basin and assess the potential for hydropower on the upper part of the Akobo River and the development of irrigation and associated multipurpose uses downstream in South Sudan – given the significant potential for hydropower on the South Sudan – Ethiopia border stretch of river, where the river falls by almost 100m.
