Thoughts on the areal change of dress and influential effects
  • Thoughts on the areal change of dress and influential effects
  • This paper presents an analysis on areal change of dress, particularly the locational change and spatial propagation. It also tries to give a study of the main factors affecting the areal change of dress.

Establishing the role of pedogenesis in changing soil hydraulic properties
  • Establishing the role of pedogenesis in changing soil hydraulic properties
  • Chronosequences provide suitable sources for the study of changes in soil hydraulic behaviour as a result of long-term pedogenesis. For a podsol chronosequence in the Scottish Highlands, data are presented to indicate the changes that have occurred
  • over 13 000 years in the saturated hydraulic conductivity in each horizon. As the soil profile has evolved into a differentiated sequence of three horizons, the resulting hydrological changes can be both measured and quantified. The results
  • are significant for interpretation of changing runoff processes and slope stability.

Late Quaternary environmental and climatic changes in Central Brazil
  • Late Quaternary environmental and climatic changes in Central Brazil
  • Paleoenvironmental changes dating back to 30,000 yr B.P. documented in a pollen record from central Brazil (lat. 19o S) permit the reconstruction of climatic changes related to shifts of the Antarctic polar fronts. The paleoclimatic inferences were

  • Bibliography ; Climatic variation ; Climatic warming ; Global change ; Greenhouse effect ; Palaeoclimatology
  • This 1992 progress report will concentrate on summarizing developments in the science of global climate change and will address three aspects of this science : developments in palaeoclimatology as providing a context for interpreting
  • the instrumental temperature record; climate change detection; and scenarios of future greenhouse gas emissions and their associated global warming projections.

A decade of surface change on a Namib linear dune
  • A decade of surface change on a Namib linear dune
  • Survey data from return visits to a linear dune in the Namib Desert provide information about change in dune form over a decade. The data demonstrate that, although change on these large features is slow, there is none the less considerable movement

  • Predicting the soil erosion response requires consideration of both direct and indirect influences of climate. Models of climate change provide input data about temperature, rainfall and wind strength, but the indirect influences of climate
  • represented through changes in land use, crop selection and farming practice will be more difficult to predict. Approaches to the forecasting of prospective soil erosion must focus at the interaction between affected environmental processes and human-induced

Impact of climatic change on agricultural production in Kansas: a four-crop analysis
  • Impact of climatic change on agricultural production in Kansas: a four-crop analysis
  • Most scenarios of greenhouse-gas climatic change predict a warmer drier Great Plains environment. The goal of this research was to determine the resulting change in soil moisture and to relate this to changes in agricultural productivity. Soil
