The integration of Europe advances as European Union is developing relations with the nearby areas, such as Mediterranean, as well as Central and Eastern Europe where it is preparing its enlargement. New large integration processes of this kind are also developing in other parts of the world, ASEAN, MERCOSUR, NAFTA, African Union, and NEPAD. These huge areas, in progress for integration, are among the most important elements of globilization and, at the same time, an answer to its challenges. All this has an impact on European societies, in what concerns both their internal organization and the relations among them. One of the main features in this context is the new role acquired by the regions. The treaties of Maastricht and Amsterdam, as well as the ongoing work of the European Convention preparing the future of the Union, have put forward important landmarks, which permit the development of regions and regional cooperation in our continent. The aim of this edited volume is to study the new forms of regional organization in different areas, levels and sectors, as they are carried out by different actors, both on the theoretical and the pragmatic point of view
