This book analyses the most recent socio-territorial trends that are developing in the Spanish metropolitan space. The first part focuses on the most recent metropolitan dynamics and demographic changes in Southern Europe. The second part discusses the most important processes in metropolitan areas: the problems of increasing social and residential vulnerability and the problems of diversity management. The third part analyses some concrete cases of the main changes and complexity in the spatial dynamics of metropolitan areas in Southern Europe. Finally, the fourth and last part provides an overview on the instruments and the resources put in place by some Southern European cities for the development of governance and citizen participation as an instrument of reaction to the social, economic and COVID crisis. By discussing the main changes and uncertainties derived from the social scenarios after the pandemic, the dynamics of social dualisation of the city, as well as the necessaryinstruments for its analysis and the main challenges in urban governance with special attention of Southern European context, this book provides an interesting read for spatial demographers, human geographers, social scientists and spatial planners.
