Urbanization is, to be sure, still manifested in the continues massive expansion of cities, city-regions, and mega-city-regions, it equally entails the ongoing socio-spatial transformation of diverse, less densely agglomerated settlement spaces that are, through constantly thickening inter-urban and inter-metropolitan infrastructural networks, being even more interlinked to the major urban centres. We are witnessing, in short, nothing less than the intensification and extension of the urbanization process at all spatial scales and across the entire surface of planetary space.
