Dominant Relations: Environment

Environment: Dominant Relations

Atmospheric carbon dioxide is function of emissions from fossil fuel burning. Water use is primarily a function of agricultural sector size (and therefore on irrigation). Forest area is dependent upon the rate of conversion of forest to crop land and grazing area.

For a causal diagram see Environment Flow Charts Overview.

For equations see Environment Equations Overview.


Key dynamics are directly linked to the dominant relations:

  • The energy submodel determines fossil fuel use, and the agricultural model determines agricultural sector size and land conversion patterns. See those models for discussion of dominant patterns and of control parameters.


Environment: Selected Added Value

The larger environmental model provides a more extended model of carbon dioxide, including oceanic absorption rates and possible impact of build-up on global temperature and agricultural patterns.
