Description :
Pleistocene to Holocene as well as recent trends in climate have an influence on the composition of savanna-forest vegetation fringes in Africa, dominated mainly by savanna and mainly forest groups of plants. The modified vegetation cover plays an important role on the runoff processes and on the discharge of the draining river systems. Therefore, this study focuses on the examination of alluvial soils and the determination of stable carbon isotopes of organic sediments on the Mbomou plateau and in the Mbari valley in the southeast of the Central African Republic. Secondly, it focuses on the impact of Quaternary environmental changes on geomorphological processes.
