  • Polarities of structure and change in urban systems : a Canadian example
  • Canada ; Changement urbain ; Croissance urbaine ; Fonction urbaine ; Hiérarchie urbaine ; Métropole ; Système urbain
  • Canada ; Large city ; Urban change ; Urban function ; Urban growth ; Urban hierarchy ; Urban system
  • The paper examines some of the contradictory assertions in the research literature regarding the on-going reorganization of urban systems through a detailed empirical analysis of the changing properties of the Canadian urban system. The analysis
  • begins with a conceptual framework that recognizes alternative logics and trajectories of change in urban systems. The paper demonstrates the diversity and rapidity of change, and the indeterminant and contradictory nature of many of the relationships
  • underlying that change.

  • Environment ; Environmental conservation ; Global change ; Social change ; Society-environment relationship
  • This review reflects on both the intellectual and policy implications of global environmental change. It explores opposing perspectives on the relationship between environmental and social change. These perspectives possess an ideological component
  • sometimes differentiated as environmentalism and ecologism. They also relate to a theoretical discourse about the nature of modern society and the sources of change.

  • Transformations in terrestrial ecosystems are increasingly regarded as an important element of global change. This article reviews recent approaches to the monitoring and modelling of deforestation and dryland degradation in tropical regions
  • . The review highlights the requirement to tailor the investigation method to the specific research question of interest. Different techniques to monitor land-cover changes at regional scales are analysed. The article stresses the needs for a better integration
  • of social science knowledge in land-cover change models and for a comprehensive theory of land-use changes.

  • Changement social ; Géographie régionale ; Monde
  • Regional geography ; Social change ; World
  • We are facing changes that will result into a new-type society. There are also conditions for a new regional geography. It should be to a greater extend oriented towards external relations in the globalized world and regional transformations
  • . The ongoing social changes bring both challenges and responsabilities. Regional geographical studies are supposed to bring actual understanding rather than to construct laws and regularities. - (MS)

  • Human impact on rivers in Hungary as reflected in changes of channel planform
  • Geomorphology and changing environments in Central Europe
  • In the second half of the 19th century, flood control measures radically changed the Hungarian river network. Channel length, slope and planform were all directly affected by regulation and also by subsequent river adjustment. In this paper selected
  • sections of 2 rivers are studied. Sinuosity and shifts and dimension changes of meanders are used to detect river mechanism countering or complying with the impact of human intervention.
