Urban expansion: from compact to fragmented form

Abstract

The new urban order in the territorialization of cities, in general, is based on the principles of an ever more fragmented and dispersed growth across the territory. However, the growth of the urban area of Maringá diverges from this new order, retaining its compact form. In this study, the urban area of Maringá is composed of the cities of Maringá, Sarandi and Paiçandu in the State of Paraná, Brazil. The objectives of this article are to define the urban form of Maringá considering the variables compact city, fragmented city and disperse city and to identify the periods of urban expansion for each variable. The timeline of this study begins with the implantation of the cities in the 1940s and continues until the year 2016, since the urban area been mapped in a decennial diachronic series. Originally compact, the urban area fragments as it expands, in a movement that continues until the 2000s. After that, the occupation of its center predominates, making it compact again. Given these points, the beginning of a new cycle or new model of urban expansion is evident for Maringá.

Settlement relationships and their morphological homogeneity across time and scale

“…Due to the strong focus on a single use of such satellite settlements, their urban form tends to be more homogeneous than their larger neighbors that have a wider variety of services or functions 20,21 . However, research on the relationship between a settlement's morphology, its relative size and its proximity to other settlements has mainly been limited to isolated focus areas around large cities 1,20,[22][23][24][25] . Whether these relationships can also be found in areas with many medium-and small-sized settlements remains to be determined.…”

Compacidade E Dispersão Urbana a Partir Das Estruturas Regionais

“…Partindo da premissa de que a expansão das cidades do norte do Paraná segue uma ordem territorial preestabelecida, a matriz rural, a forma do crescimento da mancha urbana de Londrina é apresentada por meio de uma série diacrônica elaborada em intervalos de dez anos. Essa mesma série diacrônica foi a base metodológica e analítica da pesquisa sobre a mancha urbana de Maringá (12). A periodização estabelecida e a utilização das mesmas categorias de constituição do solo urbano perimitiram traçar um paralelo entre as formas das duas manchas urbanas, que será apresentado nos resultados deste artigo.…”

“…Com o propósito de se verificar o modelo de crescimento urbano, a rede de cidades do norte do estado do Paraná, Brasil, vem sendo recentemente estudada. Os primeiros resultados sobre a mancha urbana de Maringáconstituída pelas cidades de Paiçandu, Maringá e Sarandi -revelam uma configuração urbana compacta, de expansão contínua, com alguns poucos fragmentos (9,10,11,12). Na sequência, com o mesmo procedimento metodológico, este artigo se propõe a desenvolver estudos acerca da mancha urbana de Londrina -composta pelas cidades de Cambé, Londrina e Ibiporã.…”
