The first years of the 90s have witnessed thorough political and economic changes in northern Europe. The long period of strong political separation between east and west and the less strong economic separation between the northern and southern sides of the Baltic Sea seemed to be replaced by far-reaching integration. There is no doubt that further integration will have additional impacts on the regional patterns in northern Europe. The amplitude and composition of these changes are difficult to project. In this volume a number of scholars in regional science and related disciplines (geography, economics, environmental and political sciences, planning) have brought together important material on the current processes that reshapes northern Europe. Visions andstrategies on local, national and supranational levels are penetrated in depth. A "mosaic" vision of the regional development pattern emerges highlighting the importance of cooperative and competitive strategies affecting the local conditions of European regions.
