La Mayombe (Congo) : contraintes et aménagements d'une moyenne montagne tropicale (The Mayombe (Congo) : constraints and planning in a tropical mountain)

摘要

Between Congo basin and atlantic coastline of Pointe Noire harbour, the Mayombe range, in spite of modest altitude, is a hard obstacle to cross over. Alternation of quartzites chains and clayey valleys all drowned inside evergreen forest, the Mayombe range is crossed by a railway, the C.F.C.O., built from 1921 to 1934 with great human and technical difficulties. Nowadays a new railway improves a part of the trip, but the bioclimatic environment remains hostile. A part of the forest has been the subject of a scientific survey by UNESCO in order to built a biosphere natural reserve.
