Difficulties in people’s mobility and in the flow of goods are one of the major obstacles to better the living conditions of populations in less-developed countries generally speaking, and particularly in Africa. That is true indeed for the Republic of Niger. As far as foreign trade is concerned, one can easily notice the constraints linked to the geographical location of the country, just by looking at the map of Africa. Not only its striking external isolation, but also its land-locked situation focuses a serious development issue. The size of this land-locked state and its economic weakness are the basic context for transportation in Niger. The department of Téra, which represents Niger well, allows understanding malfunctions in the transportation system and how mobility is part of the local development process. The low level of the services of transportation, the ageing infrastructures and the difficult access to means of transport are recurring problems for populations. The different stakeholders’ strategies have had limited impact on the improvement of mobility within the department. Those important malfunctions concerning people’s mobility and the flow of goods must be solved.
