There is a strong international dimension to spatial planning. European integration strengthens interconnections, development and decision-making across national and regional borders. EU policies in areas such as environment, transport, agriculture or regional policy have far-reaching effects on spatial development patterns and planning procedures. Planners in the EU are now routinely engaged in cooperation across national borders to share and devise effective ways of intervening in the way our cities, towns and rural areas develop. In short, the EU has become an important framework for planning practice, research and teaching. Spatial planning in Europe is being 'Europeanised', with corresponding changes for the role of planners.
