  • It is debatable whether tropical geomorphology is intrinsically different from the geomorphology of other places. This paper primarily examines the research themes of the last ten years or so, identifies the major trends, and attempts to predict
  • areas where interest is expected to concentrate in near future. The following topics among the current research trends are highlighted : geochemical erosion, movement on tropical slopes, rivers in the tropics, tropical landforms, hydrology
  • and sedimentation in the rainforest, denudation efficiency in the humid tropics, the Quaternary evolution and changes, and the applied side of tropical geomorphology.

  • Organic matter in tropical soils: current conditions, concerns and prospects for conservation
  • Agroforestry ; Deforestation ; Forest ; Land use ; Organic materials ; Savanna ; Soil ; Soil erosion ; Tropical zone
  • This article reviews the current status of organic matter in tropical soils beneath forest and savanna vegetation types and the contribution made to atmospheric carbon dioxide concentrations from decomposition processes in the soil and as a result
  • of tropical forest clearance. The second aim is to examine the role of soil organic matter in stabilizing soil structure, in nutrient cycling and in ion retention in tropical soils and to assess the effects of forest clearance and subsequent cultivation
  • on organic matter processes. The final aim is to evaluate possible practices for conserving soil organic matter and maximizing sustainability in tropical cultivation systems after deforestation.

  • Predicting landslides from rainfall in a humid, sub-tropical region
  • Forecast ; Landslide ; Precipitation ; Slope ; Slope dynamics ; South Africa ; Statistics ; Tropical zone
  • Topography, geology and a humid, sub-tropical climate make the Durban region on the east coast of South Africa particularly prone to sliding mass movements. Records of individual landslides and landslide events between 1970 and 1990 were compared
