Grémont Charles auteur aut IRD text journalArticle eng text/pdf born digital access Since the 1980s, the so-called "nomadic" populations in the regions of Northern Mali and Niger have embarked on an extensive process of settlement. Today they mostly live in villages or "settlement sites". But, at the same time, individuals and small groups among these same populations have considerably enlarged their area of mobility and accelerated the rate and the value of the trade in which they engage. These two phenomena could, at first sight, appear contradictory. But the observation of empirical situations shows, rather, compatibilities, similarities even, between these two concomitant phenomena. Building on innovative debates conducted in geography and sociology, this article puts forward the hypothesis that the building of villages, as well as integration into military bases and barracks, proceeds from (social) rationales of mobility, just as much as transhumance, journeys, migration. Much more than a simple displacement in space, the notion of mobility could describe an "art of doing", a way of being to others and to the world. specialized MALI NIGER 108 098 48 1 29-40 2014 0008-3968 https://www.documentation.ird.fr/hor/fdi:010072242 10.1080/00083968.2014.918322 0008-3968 [F B010072242] https://www.documentation.ird.fr/hor/fdi:010072242 https://www.documentation.ird.fr/intranet/publi/depot/2018-02-27/010072242.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-02-27 2018-05-16 fdi:010072242 fre
