The future of Mediterranean ecosystems and landscapes is clearly tied to water availability and global climate change. While modern vegetation data from the region provide a baseline for understanding relationships between aridity and vegetation composition, paleoecological records bring support for understanding vegetation responses at longer time scales. Paleoecological records show that aridity, as a feature of the Mediterranean basin, appeared early, gradually increasing up to the present time. Italy represents one of the most informative Mediterranean areas to: (i) reconstruct the response of vegetation to various climatic stresses; and (ii) assess the likely future behaviour of Mediterranean plants. Furthermore, the Italy's rich geological and stratigraphical record makes it (iii) a significant source of information on the history of Mediterranean. This course focuses on understanding the:
1. response of vegetation/environment (from 2.6 Ma) to variations in climatic forcing on orbital and millennial/submillennial (e.g. Heinrich events, D-O, Bond cycles) timescales;
2. driving and environmental context of the phases of migration and successive colonization of hominins;
3. interglacial features from 2.6 Ma for a better evaluation of the future and length of the Holocene.
