Forests are the dominant terrestrial ecosystem of Earth. They are distributed across the globe. Forests account for 75% of the gross primary productivity of the Earth's biosphere, and contain 80% of the Earth's plant biomass. Human society and forests influence each other in both positive and negative ways. Forests provide ecosystem services to humans. Forests can also impose costs, affect people's health, and interfere with tourist enjoyment. This publication presents reviews and research results on negative and positive human interference on forests, as well as ecology, management, governance, policy and economic issues. The book consists of four sections with 12 chapters derived from around the world.

Over the past decades, archaeological field surveys and excavations have greatly enriched our knowledge of the Roman countryside Drawing on such new data, the volume The Economic Integration of Roman Italy, edited by Tymon de Haas and Gijs Tol, presents a series of papers that explore the changes Rome’s territorial and economic expansion brought about in the countryside of the Italian peninsula. By drawing on a variety of source materials (e.g. pottery, settlement patterns, environmental data), they shed light on the complexity of rural settlement and economies on the local, regional and supra-regional scales. As such, the volume contributes to a re-assessment of Roman economic history in light of concepts such as globalisation, integration, economic performance and growth.
