Informational interactions and the future of cities

1998

Present-day city growth is chiefly the result of new tertiary activities such as financial and producer services, R&D, or business administration. It seems that these activities need to be more spatially concentrated than traditional manufacturing activities. These new trends affect both the structure of cities and the structure of city systems. The specific nature of the new activities concentrated in city centers makes them information intensive. These activities consume human capital, knowledge and hightech capital, which are all rapidly changing inputs; they are based on complex decisionmakingprocesses; this renders them highly information-dependent. Inasmuch as these activities are the…

Interactions, spillovers de connaissance et croissance des économies modernes. Faut-il préférer la globalisation ou la proximité géographique ?

2009

Globalisation and metropolisation in modern economies induce some locational strategies of knowledge based activities towards cities and deeply increase trade and move of ideas across cities. In that context, we study the way knowledge spillovers have influenced the economic growth of 82 European Metropolises over the 1990-2005 period. We model knowledge spillovers across cities according to three specific interaction patterns depending either on geography or on global advanced services or thought a combination of these patterns. We show that the mixed pattern matters the best for economic growth of cities in Europe.

Postmetropoli in contesti al 'margine'

2014

Il sud Europa, ad eccezione del nord Italia, è considerato come una porzione 'marginale', la 'meno globale' del continente e fino a poco tempo fa c'era chi lo dipingeva come appartenente al 'Terzo Mondo'. La Sicilia e  considerata al limite di questa 'marginalità' e, per molte ragioni, lo è. Eppure, nuovi processi sono in corso. I territori siciliani stanno attraversando notevoli fasi di cambiamento fisico, sociale ed economico, mostrando una transizione, per molti aspetti inedita, verso forme post-metropolitane. Si tratta di aree per molti aspetti paradigmatiche in grado di restituire le diverse nature del 'post' sotto il profilo spaziale, economico, demografico e sociale. Si affronterà, d…

Simulation and validation of urban dynamics with cellular automata

2018

Cet article, rédigé en 2008, présente les évolutions importantes la plateforme SpaCelle pour simuler l'évolution d'un espace à l'aide d'automate cellulaire. En particulier, la version 5 permet la structuration multi-couches des cellules pour gérer la dynamique de plusieurs variables définies sur un maillage. Elle permet aussi d'utiliser des cellules de type linéaires ou ponctuelles à travers des couches de type réseau. Les différentes couches ont leur propre dynamique et les règles peuvent faire interagir les couches entre elles. Ces fonctionnalités avancées ont permis de construire un nouveau modèle sur l'évolution de l'agglomération rouennaise plus proche de la réalité terrain en utilisan…

Gestions de l'eau et du développement urbain dans l'espace dijonnais :quels modes d'intégration territoriale ?

2006

Urban growth, jointed to technical networks, contributes to human pressure on water resources. In the meantime, the water French policy put management of urban development in accordance with catchments and hydrologic dynamics; that makes districts and intermunicipal groupings adopt new areas and action systems. The urban area of Dijon is located in three catchments and above a wide groundwater. This case shows urban water management gives greater place to precariousness and common character of water resources, even if institutional responses mainly concern town planning regulation.
