  • By using the regional case of the Oubangui River drainage area in Central Africa, the aim of this study is to focus on the intensity and frequency of flood hazards over the past 90 years at the site of Bangui. It will be discussed if the statistical
  • analysis of the Oubangui discharges from 1911 up to the present will confirm the hypothesis of a recently ongoing aridification trend evidenced by fluvial systems in northern Central Africa.

  • Rheological properties of parts of the African lithosphere and their geodynamic significance
  • Estimates of viscosity range from about 10 Pa s (i. e. 10 poise) under the East African Rift Valley system to 10 Pa s (on 10 poise) below the West African shield in Niger republic and Sierra Leone. High temperatures, low densities, low viscosities
  • and high stress gradients characterize the East African Rift Valley areas, the Afar triangle, and some of the swells e. g. Tibesti and Jebel Mara. Data from electromagnetic deep soundings, gravity and teleseismic delay time studies are incorporated
  • to present representative models of the lithosphere for the various tectonic regimes of the African continent.

  • Les plantes à tubercules de la forêt dense d'Afrique centrale
  • The different species of rain-forest plants developing starchy tubers were studied around Makokou (N. E. Gabon) and in the Lobaye River district (S. W. Central African Republic). A detailed description of the tuberous parts is given, particularly

  • Planation surfaces are well pronounced in the topography of the Republic of Guinea-Bissau. They came into being during the Late Alpine macrocycle of the relief formation. Two planated surfaces belong to the African stage (Late Cretaceous-Oligocene
  • ) and are designated as Early and Late African respectively. Since Miocene a post-African pediplain formation begins which marks the epoch of global pediplanation. The process proceeded along with erosion and alluviation in river valleys. Early Africain surface
  • remnants persist only in the South-East of the country. The Late African surface is widespread in eastern regions. Post-African pediplain can be found practically all over the country. - (L'A.).

  • Different approaches have been employed to develop South African national identities. In April 1994, a new chapter was opened for the country to search for a new South Africanism. The paper attempts to give an overview of the nationalisms which
