Issues of global environmental change, involving both climate and land-use change, require the rapid development of process-based, predictive tools of the global land surface and its dynamics. Biophysical feedbacks, for example, between the biosphere and the atmosphere could act to either enhance or diminish the greenhouse effect (Martin, 1993). In addition, the impacts of global change on the biosphere could have profound effects on global resources of wood, food, fibre, biological diversity and water (Bolin, 1991). Quantification of these feedbacks and impacts is important for helping to shape the policy responses to global warming and land use. One step in the development of such predictive capability is the creation of a dynamic global vegetation model (DGVM) that can simulate vegetation redistribution as fully coupled with the biogeochemistry of carbon, water and energy. Currently, no such model exists, but the fundamental components have been developed among different classes of ecological models.
