Resumen
The 2008 crisis entailed a turning point in the process of creating and managing cities and territories. There has been a change from a city model, based on expansive growth, which was also speculative and deregulated, had provoked an unprecedented expansion of the outskirts of towns and cities, and the artificialization of thousands of hectares of land, to a model based on the reconstruction of the original city, before the impact of the crisis. Gone are the days of urban mega-projects?source of indebtedness for local administrations- and big urbanizations, which, in many occasions, have not been inhabited. The financial, social, and residential reality requires a better thinking of the city models, as well as recuperating the neighborhoods and recomposing the social gap and conflicts, which had become affected by unemployment, evictions, and austerity policies. In this paper, two models of understanding and managing cities have been presented, as a way of identifying strengths, weaknesses, and impacts on the modern city. Several case studies have been collected at a regional level (Extremadura and Valencian Community), and at an urban level (Las Palmas, Madrid, Barcelona, Valencia, and Toledo), and even at a sub-urban level (via the study of certain neighborhoods).
