Estimations, à partir de séries d’images LANDSAT, des évolutions de stocks de carbone de différentes formations en milieu équatorial côtier - cas de Libreville au Gabon

Abstract: Le rôle des forêts dans la séquestration du carbone est important dans un contexte de changement climatique. Dans cet article, il est question d’effectuer une évaluation du stock de carbone dans la région de Libreville à partir des données de télédétection sur une période allant de 2001 à 2018. Cette évaluation des stocks de carbone végétal est basée essentiellement sur l’imagerie optique Landsat. En amont, une première analyse visant à produire une cartographie d’occupation du sol entre 2001 et 2018 a été eff… Show more

“…Senegal Organic carbon, a major determinant of soil properties and an essential component of carbon and greenhouse gas cycles, is highly sensitive to land use and management: forest, savanna, crop, grassland ( [21] [47] [48]). Thus, the estimation and variation of carbon stocks, within the sites of the Great Green Wall of Senegal, uses as proxies land cover (vegetation mapping, [39] [40] [48] [49] [50] [51]), average carbon stock values from bibliographic data from the region ([52]- [57]) and equation (3) below (Table 4).…”
