The profound transformations occurring in the world's politics, economics, demography, technology, ecology, and ethics demand a means of evaluating and adjusting to these changes. This volume focuses on global modelling and simulation studies to examine world megatrends of change and response alternatives. The authors, leading scholars drawn from around the world, discuss a variety of model applications, including the LINK project, the EPA World Model, the Global Input-Output System, and the FUGI Global Model. Implications of global change are analysed for key world the global economy and economic development, the environment, regional trade patterns, production technologies, greenhouse gas emissions, and arms reductions. This book aims to contribute to the growing body of literature supporting the development of new methods of forecasting global change and formulating policy alternatives for environmentally, socially, and politically sustainable development.
