The 21st century has been designated as the century of urban transition. Urban environments have become a key reflection of the changes in today's world of dynamic and constant flux as cities throughout the world experience fundamental social, cultural and economic transformation. Socio-cultural and urban identities are being radically transformed; globalization, internationalization and the rapid flow of information all play a significant role in changing cities and their people. During the last three decades significant investments of monetary resources and professional expertise have led to numerous projects and programmes concerning urban regeneration, housing renovation, and the revitalization of old neighbourhoods.
