A development response to forced displacement in the Sahel requires a regional approach. Such an approach would have the benefits of being able to: (i) overcome challenges relating to cross--- border movements, (ii) obtain commitments by host governments to support the prospects of displaced from neighboring countries and (iii) facilitate common approaches, shared conceptualization and learning. A regional approach will be appropriate in the context of ECOWAS cooperation, as three of five countries suffering the heaviest displacement in the region are members of that organization, namely Burkina Faso, Mali and Niger.
