This paper presents a microeconomic model of residential location that explores the emergence of a mixed belt where residents and farmers coexist beyond a city. The model is based on integrating urban economics with cellular automata in order to simulate equilibrium patterns in 2D and through time. Households commute to a CBD and enjoy neighbourhood externalities that are a function of both local residential density and farmland, or open space. They bid on the competitive land market and locate so as to maximize utility. Incremental population growth changes the neighbourhood and leads to rent adaptations. With appropriate parameter values a mixed belt may emerge between the urban and agricultural specialized areas. Settlements within this mixed area are more or less clustered or scattered depending on preferences and neighbourhood size. [less ▲]

Cette contribution propose d’explorer les processus de dispersion des ménages et de ségrégation par le revenu au sein d’un espace périurbain. La méthode consiste à simuler un modèle économique urbain avec deux types d’externalités de voisinage sur un espace cellulaire. Il permet la mise en place de processus dynamiques locaux endogènes et offre un éclairage sur la relation qui unit la morphologie des espaces périurbains et les caractéristiques des agents économiques qui s’y localisent. Des structures spatiales diverses sont générées sur deux configurations données des lots fonciers. Les équilibres présentent des structures concentriques constituées de multiples anneaux mais aussi, au cours des étapes de la croissance de la ville, des processus de dégradation cumulée ou des structures plus indépendantes de la distance.

In this report the extent of "peri-urbanisation" in Europe is analysed. The aim is to give an insight into the ways in which "peri-urban" processes are described in different European countries. The work has been undertaken for DATAR (Délégation à l'Aménagement du Territoire et à l'Action Régionale, France) as part of their ongoing study of "peri-urbanisation" in France. Urban development is one of the major concerns for the future of rural areas and ecological zones. This work contributes to the "peri-urban" debate by taking a European perspective that complements local or national case studies. The focus is on the spatial aspects of peri-urbanisation and on its recent demographic trends. The report is divided into three parts : The first part consists of a general discussion about the diversity of concepts used to analyse peri-urban processes, and provides an overview of urbanisation typologies and global trends in the EU. In the second the spatial extent and the description of peri- urban processes is discussed for different countries: The Netherlands, Belgium, Great Britain, Germany and Italy. Some bibliographical references are also given for the Nordic countries. The third part summarises the main spatial and demographic trends and identifies some of the similarities and differences between the countries considered. A bibliography is provided at the end of the report and includes references on some additional countries. It is shown how diverse can be the tools used to assess peri-urbanisation. Nevertheless, there is a clear diffusion of population towards commuting and rural areas of Europe. A growing share of national territories and population are concerned with this process. Changes in the urban-rural interface are driven by similar behaviour throughout Europe, but slight differences can be observed. Local geographic and demographic specificities, regional economic dynamism, historic settlements as well as spatial policies differentiate the evolution and morphology of European peri-urban areas today.
