The text provides literature surveys on relevant modeling issues and policy concerns. It demonstrates the application of a modeling system using a "base case" 50-year projection and a small set of scenarios. These illustrate, for example, the effects of changes in public harvest policies, variations in investments in silviculture, and globalization. It is aimed at policy makers, researchers and graduate students who are building or using forest sector models.
