This paper takes a look at the spatial and social impact of the city of Curitiba (Brazil) beyond its borders. The periphery issue is addressed through a brief overview of the city's development plans and on the expansion of its socioeconomic and modernity influence on the neighbouring municipalities in the Metropolitan Region of Curitiba. This paper aims to shed light on how new urban-urban migration flows are taking place and how projects for economic internationalization through the creation of new industrial zones and investments in agribusiness, combined with incentives from the Federal Government to build horizontal and vertical condominiums for the middle and lower classes, are being directed towards the municipalities of the metropolitan region. As a result of this new socio-spatial growth, a new periphery is now being drawn as it spreads out to areas of interest for agriculture and environmental protection, even further away from the towns/municipalities surrounding Curitiba.

Municipal markets emerged with the purpose of reorganizing the commerce of food products, significantly marking important changes in the space of the city and in the life of the population. In this sense, this paper aimed to discuss the changes that have taken place in the city of Taubaté, located in the Metropolitan Region of Vale do Paraíba and Litoral Norte (RMVPL), SP, and its relationship with the local municipal market, as well as to reflect on the importance of this place in the process of construction of the city, through the analysis of the historical context of the growth of the city. For the development of this research, a time frame was adopted, between the years 1800 to 1950, in a geohistorical perspective. in order to reflect on the relationship of this place with this growth. Therefore, a qualitative approach and exploratory research was carried out, analyzing the implantation, permanence, and architectural transformations, as well as the spatial organization that permeate the market in the different phases of the development of the municipality. Municipal Markets have always presented themselves as a connection between the countryside and the city, and between cities, as they are characterized as trade centers resulting from the intersection of trade routes and helped in the cohesive construction of the cities' cultural identity. The Taubaté market followed the city's growth process, at times connected to the process, at others, distancing itself from the dynamics of the city. However, it was a regional reference, which contributed to the growth of the city, not only because the commerce that took place there, boosted its expansion, but also because it was an access route to the Vale do Paraíba region.

This paper highlights the necessary integration between the study of the landscape and the system of urban public open spaces for city planning and management. Its objective is to analyze and characterize the landscape of the neighborhood of Bairro Efapi - Chapecó-SC, showing the constitution of its public free spaces as an articulating element of the city. The methodological approach, carried out through field surveys and mapping by geoprocessing, is structured in the analysis of a macro planning units and their subdivisions into Landscape Units (UP). The results show that the characterization of the six Landscape Units showed that the ecological and cultural problems of land use and occupation are worsening, given the urban expansion of a housing nature, intensified by the implementation of large industrial and institutional structures. The public free spaces identified were the street, the green area and the square, which are insufficient to meet the needs of the local population, as well as constituting a system capable of mediating the impacts of urbanization. The urban requalification strategies are therefore focused on the articulation of public open spaces with ecological sensitive protection areas, such as APPs, Green Areas and private vegetated areas, through the landscape requalification of the road system.

This paper discusses the production and re creation of cities' tourist imageries, noting the effects of tourism in Coimbra and Salamanca. The analysis focuses firstly on the ways cities are presented to the external gaze; secondly, on the urban invisibilities created by tourism activities; and thirdly on the circumscribed and selective nature of tourist cities. Drawing on this line of questioning, the paper pertains to the manner cities use and rebuild their images and significations, rendering them active instruments of urban development strategies. Finally, it assesses the value of heritage for tourist promotion and discusses the creation of new tourist images shaped by the rhetoric of the creativity of the urban space [ABSTRACT FROM AUTHOR]

This paper proposes to analyse the effectiveness of the Plan for the mediumsized city of Raleigh, North Carolina, USA through its planning and design of a system of Parks and Green Corridors as an example to be followed by contemporary cities, in relation to the planning and connectivity of its open space system, represented by parks, recreational areas and green corridors. In this sense, the quality of urban life of its inhabitants, free spaces, and perpetuity of the natural resources of the city of Raleigh is directly related to the opportunity of the realization of the first American plan of the network of green corridors to a capital, "A Park with a City within ", as a way to contain urban growth, minimize anthropic impacts and promote the increase of leisure and recreation areas in all areas of the city, as well as their connectivity and functionality. The effectiveness of the constitution of this integrated system, consisting of the network of green corridors, is based on the implementation and constitution of the whole plan, over a period of several years, through the outline of its characteristics, objectives, and functions. Discussions, premises, and strategies for planning, project renovation of existing structures of the park system and green corridors... [ABSTRACT FROM AUTHOR]

Urban sprawl is one of those terms that became a major keyword in the scientific sphere as well as in everyday uses, to the extent that it is often considered as self-explanatory. Based on a literature study on urban sprawl this paper highlights the plural understandings of the term that result from a lack of consensus on a common definition. Thus, this paper aims at questioning urban sprawl by asserting its polysemy. Starting with an overview of the methodologies used among the scientific community, the research reveals a dual meaning of the term, considering urban sprawl from a point of view either statistical (quantitative approach) or morphological and functional (qualitative approach). More specifically the analysis is anchored in the United States, where sprawl historically emerged and shows its most advanced expressions. Building on a selection of case studies (Las Vegas, Los Angeles, Atlanta, and Nashville), the inputs and limits of both approaches are considered, and a discrepancy is proven between perceptions and reality when studying urban sprawl in the US.

The second half of the 20th century witnessed the rapid expansion of built-up areas practically all over the world. In Portugal, this phenomenon took place particularly along the coastal strip and around its two main cities, Lisbon and Porto. Economic and demographic growth led to processes of urban expansion, which in turn bolstered the development of extensive urbanized continuums, contributing to the consolidation of the metropolitan areas and transformation of landscapes. Greater knowledge of the recent processes of urbanization is of interest to the geographical sciences, as well as to applied fields such as spatial planning. Since their initial development, Geographical Information Systems (GIS) and automatic mapping tools have opened new horizons in Cartography, with a potential which should be taken advantage also in the study of landscapes and, particularly, of urban growth. From a morphological point of view, a study of urban expansion necessarily has to be based on multitemporal mapping. More than successive static pictures, multitemporal mapping produces a dynamic image of the process, providing support to ensuing explanatory studies. In Portugal, the studies on urban expansion are limited either by the reduced scale employed or by their reduced focus (studies of small areas or single cities). Increasingly in use, techniques based on the classification and/or interpretation of satellite images produce multitemporal cartography at much larger scale and coverage. However, these techniques have limitations, given their recent development: it is not possible to map built-up areas prior to 1980. The limitations in producing multitemporal urban cartography at regional and sub-regional scales could be mitigated by an approach integrating information from old editions of topographic mapping in a GIS, which could thus track the process of urban growth for a certain time frame. In this paper, this approach was employed to prepare a multitemporal cartographic database of built areas, with three moments comprising the second half of the 20th century. These databases also served to produce a set of "morphodensimetric" indicators related to built-up areas, for the three temporal moments, leading to analyses on the pace and forms of recent urbanization in the area under study (the Porto metropolis). We believe that the approach proposed can open new perspectives for cartographic production, as well as for the study and understanding of recent urbanization processes and its implications on the landscape dynamics.

KNOWLEDGE, INNOVATION AND TERRITORY. The process of globalization and the knowledge-based economy pose new challenges for the development of cities and regions, due to the establishment of new organizational architectures and spatial networks of knowledge. The combination of local and distant networks of knowledge have profound implications on innovation and territorial development, requiring a renewed role in the action of regional and local institutions, traditionally trained to promote local dynamics of innovation. This article specifically discusses the issues of buzz, geographical proximity and agglomeration and distant innovation networks, and provides the theoretical "background" for the papers published in this special issue on the theme "Knowledge, Innovation and Territory."

During the first decades of the 20th century, Madrid underwent crucial socio-economic and spatial transformations which reinforced its metropolitan role. These new dynamics coexisted and came into friction with the symbolic and political functions of the national capital. This paper aims to examine the double and sometimes conflictual role of Madrid as a historical capital and an emergent metropolis. The first section focuses on the study of these urban transformations in order to better comprehend the simultaneous process of metropolitan formation and of capital assertion. The second section deals with the spatial and political projects for Madrid of Second Spanish Republic (1931-1939). Furthermore, the diffusion at the national level of the notion of Greater Madrid, which had only been employed till the 1930s by local actors, will be discusses.

Este artigo procura abordar a urbanização brasileira sob uma perspectiva comparativa, a partir da construção de um Indicador de Dispersão Urbana, visando contribuir na análise dos desafios para uma urbanização sustentável. Trata-se da busca de evidências que confirmem as proposições teóricas de uma nova etapa do desenvolvimento da sociedade moderna (riscos socioambientais) e os desafios para análise da relação população-ambiente nos contextos urbanos. Para compor um indicador sintético de dispersão urbana para as aglomerações urbanas brasileiras, foram consideradas as seguintes dimensões sociais e espaciais: densidade, fragmentação, orientação e centralidade. Os resultados obtidos foram compatíveis com as evidências apontadas pela literatura internacional, expondo os novos desafios para planejamento urbano e ambiental.Este artículo pretende abordar la urbanización brasileña bajo una perspectiva comparativa, a partir de la construcción de un Indicador de Dispersión Urbana, con el objetivo de contribuir con el análisis de los desafíos para una urbanización sustentable.

This objective required both theoretical and methodological investments in the search for evidence which could confirm the theoretical proposal of a new stage of the development of modern society (social and environmental risks) and the challenges involved in analyzing the population-environment relationship in urban contexts. The index that was developed considered four social and spatial dimensions in order to compose a synthetic index of urban dispersion for Brazilian urban agglomerations: Density, Fragmentation, Linearity and Centrality. Results are compatible with the evidence presented in the international literature and suggest new challenges for urban and environmental planning.

The Portland Metropolitan Area, OR, is known for introducing growth boundaries to contain urban sprawl in the United States of America. This controversial policy is charged of pushing up housing price and intensifying road congestion. This paper updates the debate by examining the existing empirical evidences up to 2010 in comparison with other metropolitan areas where urban growth is less regulated. Portland’s regional planning’s results are mixed. It contains urban growth efficiently, but it also has unwanted side-effects that support the Conservative’s critics of regional planning.
