International Futures (IFs) with Pardee is a computer simulation of global systems for classroom or research use. IFs can be used to teach or study demographics, economics, food, energy, the environment, and international politics. It is especially suitable for analysis of sustainable development and for examining the human dimensions of global change.
See Barry Hughes and Evan Hillebrand, Exploring and Shaping International Futures (Boulder, CO: Paradigm Publishers, 2006) for a book on IFs suitability for classroom and policy analysis support. The book is available from Paradigm at their website.
