Nature : Trees & Forests

Long-range models that include product and resource detail are essential to meaningful analysis of both industry and resource sustainability. Taking this as its central argument, this book provides essential reading to anyone interested in projecting the future of either the forest products market and/or the forest resource conditions. It is aimed at policy makers, model builders, researchers and graduate students who are building or using forest sector models, as well as at forest industry managers and analysts. While focusing on a specific modeling system ??? the US Timber Assessment models ??? the authors highlight the general elements that might comprise a forest-sector market model of any country or region. Approaches to policy analysis are also general and equally applicable to both national and multi-national forest policy development outside the US ??? particularly in relation to on-going efforts to formulate national programs of sustainable forestry. The text provides literature surveys on relevant modeling issues and policy concerns, and demonstrates the application of the modeling system using a ???base case??? 50 year projection and a small set of scenarios to illustrate, for example, the effects of changes in public harvest policies, global change, variations in investments in silviculture, and globalization. Darius Adams and Richard Haynes are widely recognized as leading experts in the forest sector modeling field. more...

The Global Forest Products Model (GFPM) book provides a complete introduction to this widely applied computer model. The GFPM is a dynamic economic equilibrium model that is used to predict production, consumption, trade, and prices of 14 major forest products in 180 interacting countries. The book thoroughly documents the methods, data, and computer software of the model, and demonstrates the model's usefulness in addressing international economic and environmental issues. The Global Forest Products Model is written by an international multi-disciplinary team and is ideal for graduate students and professionals in forestry, natural resource economics, and related fields. It explains trends in world forest industries in the simplest terms by explaining the economic theory underlying the model. It describes six applications of the GFPM, three of which were commissioned by the Food Agriculture of the United Nations, the USDA Forest Service, and New Zealand Research.The authors show how to apply the model to real issues such as the effects of the Asian economic crisis on the forest sector, the effects of eliminating tariffs on international trade and production, and the international effects of national environmental policies. They provide complete explanations on how to use the GFPM software, prepare the data, make the forecasts, and summarize the results with tables and graphs. more...
