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