Impatto di Inquinamento Atmosferico e Cambiamento Climatico Sugli Ecosistemi Forestali: Le Attività del Research Group 7.01 della IUFRO

Abstract

"Impact of environmental pollution and climate change on forest ecosystems: the activity of the IUFRO Research Group 7.01. The IUFRO RG 7.01 deals with 'Impacts of Air Pollution and Climate Change on Forest Ecosystems.' Climate change and air pollution are closely linked, although in applied scientific research and even more in political negotiations they have been largely separated. Many of the traditional air pollutants and greenhouse gases have not only common sources, but may also interact physically and chemically in the atmosphere causing a variety of environmental impacts on the local, regional and global scales. The impacts on forest ecosystems have been traditionally treated separately for air pollution and climate change. However, the combined effects of numerous climate change and air pollution factors may significantly differ from a sum of separate effects due to an array of various synergistic or antagonistic interactions. The net effect varies for different ecosystem types and geographic regions, and depends on magnitude of climate or air pollution drivers, and types of interactions between them. This paper reviews the links between air pollution and climate change and their interactive effects on forests. A simultaneous addressing of the air pollution and climate change effects on forests is an opportunity for capturing synergies and avoiding overlaps between two lines of traditional research. This could result in more effective research, monitoring and management as well as better integration of environmental policies."
