Summarizes existing IUFRO activities and presents the conclusions and recommendations of the Task Force. The subject area of the Task Force is the world-wide interaction of global climatic change, air pollution and forests, especially the effects of climate change on forests, the effects of air pollution on forests and the effects of forests on climate change.

Considerable emphasis has been placed on the interactions between environmental change and forests in recent years. Reports have been produced detailing scenarios of forest development associated with particular changes in climate. Similarly, scenarios have been produced looking at likely trends in air quality. However, many studies have failed to recognize that some of the biggest changes for forests are related to the socioeconomicenvironment rather that the physical environment. This book considers the interactions between forestry and environmental (climatic) change, from social and economic perspectives.

Air pollution has been recognised as a potential problem for forests for nearly 150 years. Today, sulphur dioxide, fluorides, heavy metals and ozone are a significant problem, usually from large scale sources in industrial and urban areas. Problems are exacerbated in those regions where there is a poor understanding of the factors involved in forest decline and destruction and no rigorous control over it has been established. This book is the first report from the International Union of Forest Research Organization's (IUFRO) Task Force on Environmental Change and provides an assessment of the extent of air pollution impacts on forests in heavily polluted regions. It includes case studies from Russia, Ontario (Canada), California and the Mediterranean region. It is also the first volume in a new book series covering many areas of forestry research, published by CABI Publishing in association with IUFRO.

This book provides a review, written by international forest scientists, of what is known about the impact of elevated CO2 and other greenhouse gases, on forest ecosystems.
