This diagram represents the carbon model for the Aleutian ecosystem. The values in each compartment represent metric tons (103) of carbon at steady state. The numbers on the arrows represent the flux of carbon (metric tons year -1) between compartments.
Is it feasible to produce the interdisciplinary models needed in integrated assessment?
An anthropological study of Aleut Indian culture was integrated with an ecosystem model to assess impacts on the marine versus upland ecosystems.
The study analyzed the relative sensitivity of the Aleut culture to the marine and terrestrial environments and found four orders of magnitude greater sensitivity to changes in the marine system. This dependence on the marine system is justified by the relative stability of the ocean ecosystem and its insensitivity to environmental changes.
