In the district of Tanguieta, the rise of temperature, the change in rain occurrence and extreme meteorological scales, have an impact on the different components of the pastoral system. Mountains confer each area, each valley a particular identity, giving the biodiversity additional dimensions. The present research work contributes to a better apprehension of the impact of the climate variability on the pastoral activity in the district of Tanguieta. The methodology used here goes through two steps: in the one hand, it is concerned with the literature related to the climate change issue, and its impacts on the pastoral activity in mountain area; in the other hand, it deals with investigations carried out with people working in the area about the impacts of the climate change on that pastoral activity, together with the spontaneous adaptations made by the breeders. This methodology has been completed by the PEIR analysis. Analysis of the climate parameters shows the global lowering tendency of rains with a series of exceeding or watery years (1950-1969) and a series of shortfall or dry years (1970-2010). Then, a global tendency of increased temperature and a growing wind speed is recorded. Finally, the early drying up of water and the lack of natural fodder have provoked some disease vectors in animals, and pastoring problems to the breeders.

Abstract
In the district of Tanguieta, the rise of temperature, the change in rain occurrence and extreme meteorological scales, have an impact on the different components of the pastoral system. Mountains confer each area, each valley a particular identity, giving the biodiversity additional dimensions. The present research work contributes to a better apprehension of the impact of the climate variability on the pastoral activity in the district of Tanguieta. The methodology used here goes through two steps: in the one hand, it is concerned with the literature related to the climate change issue, and its impacts on the pastoral activity in mountain area; in the other hand, it deals with investigations carried out with people working in the area about the impacts of the climate change on that pastoral activity, together with the spontaneous adaptations made by the breeders. This methodology has been completed by the PEIR analysis. Analysis of the climate parameters shows the global lowering tendency of rains with a series of exceeding or watery years (1950-1969) and a series of shortfall or dry years (1970-2010).

Abstract: (french)
Dans la commune de Tanguiéta, la hausse des températures, le changement des régimes de pluie et les épisodes météorologiques extrêmes influent sur les différentes composantes du système pastoral. Les montagnes confèrent à chaque lieu, chaque vallée, une identité particulière, et donc donnent à la biodiversité des dimensions supplémentaires. Cette étude contribue à une meilleure connaissance de l’impact des variabilités climatiques sur l’activité pastorale dans la commune de Tanguiéta. La démarche méthodologique repose sur les deux étapes suivantes : d’une part, celle de la littérature traitant de la question du changement climatique et de ses incidences en zone de montagne sur l’activité pastorale; d’autre part, celle d’enquêtes conduites auprès d’acteurs locaux portant sur les impacts du changement climatique sur ladite activité et les adaptations spontanées mises en œuvre par les éleveurs. Cette démarche a été complétée par l’analyse PEIR. L’analyse des paramètres climatiques révèle, la tendance générale des hauteurs de pluies à la baisse avec une série des années excédentaires ou humides (1950-1969) et une série des années déficitaires ou sèches (1970-2010). On note ensuite, une tendance générale de la température à la hausse et une augmentation de la vitesse du vent. Et enfin le tarissement précoce des cours d’eau et le manque du fourrage naturel ont engendré certains vecteurs de maladies chez les animaux et des difficultés de pâturage chez les éleveurs.
