  • The decline of tropical forests
  • Forest ; Forest fire ; Forest policy ; Logging ; Overexploitation ; Pastureland ; Tropical rain forest ; Vegetation degradation
  • The area of the tropical forests has been shrinking fast in the last decades and, moreover, considerable parts of the remaining natural forests are in a process of degradation, mainly due to overexploitation, intensified pasture farming and frequent
  • fires. This process of decline in large parts of the tropical forest belt concerns more and more the public and politicians in the industrialized countries as well as increasingly also in parts of the developing countries. - (L'A.).
  • Tropical secondary forests
  • Deforestation ; Ecosystem ; Fauna ; Forest ; Forestry ; Tropical rain forest ; Vegetation dynamics

  • This paper reviews current methods for constructing global knowledge of changes in tropical forest area, carbon density, biodiversity and ecosystem services. It finds a deficiency in formal institutions for global measurement and constructing global
  • knowledge. There is growth in interdisciplinary research into modelling forest change and estimating carbon emissions using remote sensing data, but not in studying biodiversity. Continuing uncertainty has implications for implementing the Reduced Emissions
  • from Deforestation and Degradation (REDD) scheme. Uncertainty could be reduced by expanding formal scientific institutions, e.g. by establishing an operational scientific global forest monitoring system, and devising formal generic rules

  • Africa ; Central Africa ; Ecological catastrophe ; Ecology ; Landscape dynamics ; Tropical rain forest
  • Today the Central African rain forest is going to be destroyed and suffers by many disturbances. Economical and political crises with long lasting civil wars and thousand of refugees have locally led to a significant decrease of forested area
  • . But research in geo- and biological sciences over the last 30 years have proved that the ecosystem rain forest is not as stable as supposed. It had been dramatically changed by natural variations in climate during the Last Glacial Maximum (LGM) and also during
  • the Holocene. The study demonstrates by many examples from Central Africa in which way the recent rain forest environments were changed in the past. - (IFL)

  • Phytoliths from archaeological sites in the tropical forest of Ituri, Democratic Republic of Congo
  • Archeological site ; C 14 dating ; Congo ; Forest ; Lateglacial ; Palaeo-environment ; Quaternary ; Vegetation dynamics
  • Phytoliths record late Quaternary vegetation at 3 archaeological sites in the Ituri rain forest. The oldest deposits, dated to ca. 19,000 to 10,000 C 14 yr B.P., contain abundant phytoliths of grasses but also enough arboreal forms to show
  • that the landscape was forested. These results suggest that the northeastern Congo Basin was forested when it was settled by humans in the late Pleistocene and that the region remained settled while its forest changed in structure and composition thereafter.
  • The AA. examine the hypothesis that soil chemical properties other than nitrogen supply partly explain the altitudinal changes in the rain forest. They also compare the soils on Volcan Barva with those on several other tropical mountains to see
  • if differences in soil chemistry are likely to be the cause of differences in forest structure between mountains.
