Sobre IBD

L’élevage est une activité socio-économique d’importance majeure dans le Sahel. Aujourd’hui, les activités humaines dégradantes couplées à la variabilité des conditions climatiques ont entraîné la fragilisation des écosystèmes pastoraux et accéléré la dégradation des ressources naturelles dont les effets se répercutent durement sur les conditions de vie des populations vivant essentiellement de productions agrosylvopastorales. C’est dans ce contexte que s’inscrit cette étude réalisée dans la zone pastorale de Gaongo-sud qui est située dans le secteur nord soudanien de la région du Centre-sud au Burkina Faso. L’objectif global de cette étude est de contribuer à une gestion durable des ressources pastorales, à travers l’analyse de sa dynamique spatiotemporelle en utilisant des outils de Système d’Information Géographique (SIG) et de télédétection, couplée à des enquêtes de terrain. Des images Landsat 7 (ETM+) de 2000, Landsat 5 (TM) de 2010 et Landsat 8 (OLI-TIRS) de 2020 ont été classifiées selon la méthode supervisée, à l’aide de l’algorithme du maximum de vraisemblance. L’étude a permis d’analyser les changements intervenus entre 2000 et 2020.

    Ana Isabel Pereira Cardoso / Teresinha M. Gonçalves
    Life in cities has distanced human beings from nature and made it difficult to understand the ecology of life dependent on the environment. Urban water collection and distribution processes contribute significantly to the fragmentation of knowledge and the vital recognition of the water cycle. Without the effective participation of the subject in environmental actions, it is no...

    Bret C. Harvey / Steven F. Railsback
    Ecologists now recognize that the dynamics of populations, communities, and ecosystems are strongly affected by adaptive individual behaviors. Yet until now, we have lacked effective and flexible methods for modeling such dynamics. Traditional ecological models become impractical with the inclusion of behavior, and the optimization approaches of behavioral ecology cannot be use...
