Knowledge about vegetation and fire history of the mountains of Northern Sicily is scanty. We analysed five sites to fill this gap and used terrestrial plant macrofossils to establish robust radiocarbon chronologies. Palynological records from Gorgo Tondo, Gorgo Lungo, Marcato Cixé, Urgo Pietra Giordano and Gorgo Pollicino show that under natural or near natural conditions, deciduous forests (Quercus pubescens, Q. cerris, Fraxinus ornus, Ulmus), that included a substantial portion of evergreen broadleaved species (Q. suber, Q. ilex, Hedera helix), prevailed in the upper meso-mediterranean belt. Mesophilous deciduous and evergreen broadleaved trees (Fagus sylvatica, Ilex aquifolium) dominated in the natural or quasi-natural forests of the oro-mediterranean belt. Forests were repeatedly opened for agricultural purposes. Fire activity was closely associated with farming, providing evidence that burning was a primary land use tool since Neolithic times. Land use and fire activity intensified during the Early Neolithic at 5000 bc, at the onset of the Bronze Age at 2500 bc and at the onset of the Iron Age at 800 bc. Our data and previous studies suggest that the large majority of open land communities in Sicily, from the coastal lowlands to the mountain areas below the thorny-cushion Astragalus belt (ca. 1,800 m a.s.l.), would rapidly develop into forests if land use ceased. Mesophilous Fagus-Ilex forests developed under warm mid Holocene conditions and were resilient to the combined impacts of humans and climate. The past ecology suggests a resilience of these summer-drought adapted communities to climate warming of about 2 °C. Hence, they may be particularly suited to provide heat and drought-adapted Fagus sylvatica ecotypes for maintaining drought-sensitive Central European beech forests under global warming conditions.

This paper analyses the recent process of state decentralisation in Italy from the perspectives of political science and constitutional law. It considers the conflicting pressures and partisan opportunism of the decentralising process, and how these have adversely affected the consistency and completeness of the new constitutional framework. The paper evaluates the major institutional reforms affecting state decentralisation, including the 2001 constitutional reform and the more recent legislation on fiscal federalism. It argues that while the legal framework for decentralisation remains unclear and contradictory in parts, the Constitutional Court has performed a key role in interpreting the provisions and giving life to the decentralised system, in which regional governments now perform a much more prominent role. This new system of more decentralised multi-level government must nevertheless contend with a political culture and party system that remains highly centralised, while the administrative apparatus has undergone no comparable shift to take account of state decentralisation, leading to the duplication of bureaucracy at all territorial levels and continuing conflicts over policy jurisdiction. Unlike in federal systems these conflicts cannot be resolved in Italy through mechanisms of “shared rule”, since formal inter-governmental coordination structure are weak and entirely consultative.
