Is the international transhumance corridor in Sahel an archetype of multi-sited territory ? Corridor is a common contemporaneous feature in spatial development policies. It makes it possible to promote and protect mobility in a system with numerous boundaries. Thus in Sahel where zoning and territorialization have progressively bounded the open space, transhumance and herder's way of life need equipped and secure corridors. If the corridor is an assemblage, which combines the passageway for its linking function along with nodes and gateways, then it deals with territoriality. But would it be pertinent to use the expression “multi-sited territory” for qualifying the international transhumance corridor in Sahel ? This paper attempts to respond to this question by analyzing the experience in assembling this international transhumance corridor in Sahel and by taking into account its political dimension.
