Consequences of Climate Change on Historic Gardens: A Methodological Issue for Future Studies

Historic gardens are fragile systems, in which artificial and natural elements are strictly bonded. The threat of climate change can easily modify the unique composition of each garden, resulting in a variety of problems connected to the preservation of this particular heritage. A range of case studies in Italy are analysed here to find a methodology in preserving the connection between architecture and vegetation. Three main issues are analysed: increasing or decreasing humidity, the variation in rainfall level and the resulting change of vegetation and biological patina, in some cases involving the architecture’s health.
