En zone sahĂ©lienne oĂč les ressources ligneuses sont relativement rares, lâespĂšce Leptadenia pyrotechnica joue un rĂŽle trĂšs important dans la vie des populations locales. La prĂ©sente Ă©tude dont lâobjectif est de rĂ©pertorier les connaissances locales sur les modes dâutilisation et de gestion des peuplements naturels par les populations locale de Leptadenia pyrotechnica a Ă©tĂ© conduite dans la rĂ©gion de Diffa. Des enquĂȘtes ethnobotaniques ont Ă©tĂ© conduites au niveau de cinq villages. Il sâagit de: Issari; Guelborno Mounimari, Jalori, Joulou KriyĂ© et le marchĂ© de Digurdi. Dans lâensemble des villages, un total de 150 personnes a Ă©tĂ© interviewĂ© Ă travers des entretiens individuels. Les principales rubriques du questionnaire administrĂ© sont relatives aux principales utilisations et leur impact sur la ressource. Il ressort de lâĂ©tude que toutes les parties de Leptadenia pyrotechnica (feuilles; rameaux, tiges, racines, Ă©corce et la sĂšve) sont utilisĂ©es par les diffĂ©rents groupes ethniques et socioprofessionnels de la zone dâĂ©tude (Haoussa, Peulh et Kanouri). Cependant, la connaissance de lâimportance et les diffĂ©rentes catĂ©gories dâutilisation dĂ©pendent dâun groupe Ă un autre. Les principales catĂ©gories dâutilisations dĂ©nombrĂ©es dans le cadre de la prĂ©sente Ă©tude sont: lâutilisation comme bois Ă©nergie, fixation des dunes, fourrage et pharmacopĂ©e traditionnelle. La fixation des dunes et la transhumance sâavĂšrent ĂȘtre les principaux facteurs limitant la disponibilitĂ© de cette espĂšce. Pour une conservation durable de lâespĂšce, une norme de prĂ©lĂšvement de Leptadenia pyrotechnica doit ĂȘtre dĂ©finie pour la fixation des dunes et la capacitĂ© de charge des formations Ă Leptadenia pyrotechnica doit ĂȘtre contrĂŽlĂ©e vis-Ă -vis des transhumances.

English Title: Ethnobotanical importance of Leptadenia pyrotechnica Forsk. in the department of Diffa in Niger
English Abstract
In the Sahelian zone where wood resources are relatively rare, the species Leptadenia pyrotechnica plays a very important role in the lives of local populations. The purpose of this study, which is to identify local knowledge on the use and management of natural stands by local populations of Leptadenia pyrotechnica, was conducted in Diffa region. Ethnobotanical surveys were conducted at five villages. These are: Issari; Guelborno Mounimari, Jalori, Joulou Kriyé and Digurdi market. In all the villages, a total of 150 people were interviewed through individual interviews. The main sections of the questionnaire administered relate to the main uses and their impact on the resource. The study shows that all parts of Leptadenia pyrotechnica (leaves, twigs, stems, roots, bark and sap) are used by the different ethnic and socio-occupational groups in the study area (Hausa, Fulani and Kanuri). However, knowledge of importance and the different categories of use depend on one group to another. The main categories of uses enumerated in this study are: wood energy use, dune fixation, fodder and traditional pharmacopoeia. The fixation of the dunes and the transhumance appear to be the main factors limiting the availability of this species. For a sustainable conservation of the species, a Leptadenia pyrotechnica sampling standard must be defined for the fixation of the dunes and the carrying capacity of Leptadenia pyrotechnica formations must be checked against transhumance.
