The purpose of this article is to analyze urban form through the mapping of morphological indices, namely impervious surface fraction, building density, verticality, height/width ratio, roughness length, and porosity, to support urban planning in the city of João Pessoa, PB, in northeastern Brazil. The application of this study identifies and calculates such significant indices for the city’s urban space from a Geographic Information System (GIS) model. The spatial indices play notable roles in climate at different scales, developing guidelines to maximize environmental quality, promote improvements to thermal comfort, minimize the urban heat island in the city of João Pessoa, and provide relevant data (considering microclimate aspects), guiding decisions related to the planning process.

Currently, there is a significant increase in the need to include residents in the urban planning process, in which they, along with other actors (for example, the city administration, developers, business structures) will become participants in making decisions about the fate of urban space. Interacting with the residents, the authorities directly receive feedback that helps to prevent the discontent of the population with respect to those or other decisions. The article considers some aspects of population involvement in urban planning as one of the primary tasks of urban planners.

Nowadays, urban space has become more fragmented and largely consists of many unconnected enclaves. The significance of neighborhood amenities to resident’s quality of life has been identified in the recent literature. However, studies have inadequately explored the real experience of residents in their use of neighborhood amenities under the gated urban form. Since the 1990s the urban environment of many Chinese cities has been re-shaped by the large creation of gated neighborhoods. Based on a case study in the city of Shenzhen, this paper draws upon evidence of residential satisfaction with local amenities to reveal a significant variation between different neighborhoods. The outcome of the enlarged social differentiation is a result of imbalanced micro-level urban development. The findings also provide new evidence demonstrating the increased fragmentation of society as the consequence of urban privatization. By linking the planning process with the social outcome, this paper reflects on the current strengths and weaknesses of the Chinese urban planning system.

AbstractThis article examines the ways in which nationalism transformed Greek urban space during the nineteenth and early twentieth centuries. Through urban planning, architecture, archaeology, the destruction of Ottoman material remains and the promotion of Ancient Greek and (later) Byzantine heritage, urban space was gradually hellenized and cleansed of its Ottoman past. Specific examples, including the case of Thessaloniki, where the strong Ottoman character of the city was gradually effaced, are examined so as to outline the aims and the patterns of this transformation.

Considerando a dinâmica e a estrutura urbana de Belém no início do século XXI como expressão da acumulação das intervenções urbanas e das práticas de planejamento e gestão do espaço da cidade, analisa-se a genealogia do planejamento urbano para compreender a produção de um espaço que tem como característica a negação da natureza e a produção da desigualdade entre classes sociais. Nesse aspecto, identificou-se três períodos específicos que produziram impactos significativos na produção do espaço urbano de Belém: o terceiro quarto do século XVIII (1755 – 1777) com as reformas promovidas no período Pombalino na Amazônia, momento de expressão de uma modernidade urbana e arquitetônica; o final do século XIX e a primeira década do século XX (1890 – 1910), momento de ascensão da economia regional a partir da intensificação de atividades extrativas que produziram reformas urbanísticas com tons higienistas e; por fim, o período entre 1940 e 1970, que marcou uma série de propostas de planejamento com viés técnico-burocrático na produção do espaço. Do ponto de vista da metodologia adotada, estabeleceu-se como percurso de pesquisa: i) levantamento bibliográfico de caráter teórico e empírico da temática; ii) levantamento documental acerca das práticas de planejamento e intervenção dos períodos destacados com base em legislação, planos e projetos de cada um dos períodos; iii) coleta de iconografia representativa da época as quais as políticas foram executadas. Apresenta-se como resultados a hipótese de que a narrativa de uma pretensa ausência de planejamento como fator explicativo dos problemas da cidade é um discurso que não tem base na realidade, posto que historicamente é exatamente o oposto que a pesquisa indica, as modalidades de planejamento efetivadas em Belém acentuam problemas como a segregação socioespacial.Palavras-Chave: História, Planejamento Urbano, Modernidade, Belém.AbstractConsidering the dynamics and urban structure of Belém at the beginning of the 21st Century as an expression of the accumulation of urban interventions and planning and management practices of the city, the historical genealogy of urban planning is analyzed as a way of understanding production of a space that has as characteristic the negation of the nature and the production of the inequality between social classes. In this aspect, three specific periods were identified that produced significant impacts on the production of the urban space of Belém: the third quarter of the seventeenth century (1755 - 1777) with the reforms promoted in the Pombaline period in the Amazon, a time of expression of an urban and architectural design; the end of the nineteenth century and the first decade of the twentieth century (1890 - 1910), a time of great rise of the regional economy from the intensification of extractive activities that produced urban reforms with hygienic tones; and finally, the period between 1940 and 1970, which marked a series of planning proposals with a bureaucratic technical aproach in the production of space in Belém. This work established as following research methodology: i) survey bibliographical of theoretical and empirical character of the analyzed subject; ii) documentary survey of the planning and intervention practices of the highlighted periods based on municipal, state and federal legislation, as well as the master plans and development plans of the periods; iii) collection of iconography representative of the time to which the policies were executed in the urban space. The hypothesis is that the narrative of a supposed absence of planning as a factor of the city's problems is a discourse that has no basis in reality, since historically it is exactly the opposite that the research indicates, that is, the modalities in Belém accentuate problems such as socio-spatial segregation.Keywords: History, Urban Planning, Modernity, Belém.

This article explores ‘dialectical design dialogues’ as an approach to engage with ethics in everyday urban planning contexts. It starts from Paulo Freire’s pedagogical view (1970/2017), in which dialogues imply the establishment of a horizontal relation between professionals and amateurs, in order to understand, question and imagine things in everyday reality, in this case, urban transformations, applied to participatory planning and enriched through David Harvey’s (2000, 2009) dialectical approach. A dialectical approach to design dialogues acknowledges and renegotiates contrasts and convergences of ethical concerns specific to the reality of concrete daily life, rather than artificially presenting daily life as made of consensus or homogeneity. The article analyses an atlas as a tool to facilitate dialectical design dialogues in a case study of a low-density residential neighbourhood in the city of Genk, Belgium. It sees the production of the atlas as a collective endeavour during which planners, authorities and citizens reflect on possible futures starting from a confrontation of competing uses and perspectives of neighbourhood spaces. The article contributes to the state-of-the-art in participatory urban planning in two ways: (1) by reframing the theoretical discussion on ethics by arguing that not only the verbal discourses around designerly atlas techniques but also the techniques themselves can support urban planners in dealing more consciously with ethics (accountability, morality and authorship) throughout urban planning processes, (2) by offering a concrete practice-based example of producing an atlas that supports the participatory articulation and negotiation of dialectical inquiry of ethics through dialogues in a ‘real-time’ urban planning process.

La Ciudad de Nueva York fue pionera en la aplicación de un sistema de planificación de control urbano que pusiera orden y concierto a una ciudad que rebasa los 5 millones de habitantes a principios del siglo XX. Tal complejo organismo urbano, inédito hasta ese momento, fue objeto del más ambicioso plan urbano sobre una ciudad construida.Este artículo se destina al estudio de este originario plan urbano de 1916, el cual sentaría las bases, unas ciertamente visionarias otras excesivas, de la construcción de la Ciudad de Nueva York en todo el siglo XX. La Building Zone Resolution se creó con dos fines: resolver los problemas de congestión humana en un espacio reducido, la ciudad del presente, y proponer una visión del espacio urbano en las décadas venideras, la ciudad del futuro.El artículo es un compendio de diez textos cortos y un epílogo, que junto a sus respectivos diez documentos gráficos, construyen el corpus de la investigación. El lector pues se enfrenta a un ensayo gráfico formado por pequeños capítulos que le sumergirán en los orígenes de la primera ciudad vertical de la historia.PALABRAS CLAVE: Nueva York; Planeamiento; Visión urbana.The city of New York was a pioneer in the implementation of an urban control planning system that set in order a city that exceeds five million people in the early twentieth century. Such complex urban organism – invaluable until that moment – was the target for the most ambitious urban planning on a built city.This paper focuses on the study of this initial urban planning from 1916, which would set the basis, certainly some visionary yet others excessive, for the building of New York City throughout the 20th century. The Building Zone Resolution was created with two purposes: to solve the issues related to the human bundle in a limited space, the city of the present, and to aim a vision of the urban space in the forthcoming decades, the city of the future.The article is a compendium of ten short texts and one epilogue, which in combination with ten graphic documents, frame the corpus of this investigation. Thus, the reader will face a graphic essay composed by a series of brief chapters that highlight the beginning of the first vertical city in history.KEYWORDS: New York; Planning; Urban vision.

R e s u m o O artigo problematiza a literatura crítica sobre o Projeto Eixo Tamanduatehy (Santo André) no sentido de enraizá-la na trajetória específica da cidade de Santo André e de contribuir com a reflexão sobre o significado das “experiências reais” de planejamento estratégico urbano no cenário atual da globalização neoliberal. Argumentamos que a ausência de uma leitura de três dimensões entrelaçadas dificultou uma compreensão adequadado legado deste projeto, isto é: (I) a construção política e contestada da escala local, além de seu significado para a disputa de hegemonia sobre a gestão urbana; (II) o planejamento estratégico,a neoliberalização e a emergência de uma representação hegemônica do espaço urbano a partirdo Projeto Eixo Tamanduatehy e (III) planos, projetos estratégicos e a emergência de novos espaços de representação.Palavras-chave Empresariamento urbano; planejamento estratégico; Projeto Eixo Tamanduatehy. A b s t r a c t In this paper the critical literature on the Project Eixo Tamanduatehyis highlighted in a problematic perspective, in the sense of embedding it within the specific trajectory of the city of Santo André, and to contribute with a reflection on the significanceof the “real experiences” of strategic urban planning in the present scenario of neoliberal globalization. Our argument is that the absence of an analysis on three interlinked dimensions has made an adequate understanding of the legacy of this project more difficult, that is: (i)the political and contested nature of scale, besides its significance for the hegemonic disputesover urban management; (ii) strategic planning, neoliberalization and the emergence of ahegemonic representation of urban space on the basis of the Project Eixo Tamanduatehy; and (iii) plans, strategic projects and the emergence of new spaces of representation.Keywords Projeto Eixo Tamanduatehy; strategic planning; urban entrepreneurialism;.

In the context of the European city, the regeneration of former industrial sites is a unique opportunity to actively steer urban development. These plots of land gain strategic importance in actively triggering development on the city scale. Ideally, these interventions radiate beyond the individual site and contribute to the strengthening of the location as a whole. International competition between locations is rising and prosperous development a precondition for wealth and wellbeing. This approach to the regeneration of inner city plots makes high demands on all those involved. Our framework suggests a stronger focus of the conceptualization and analysis of idiosyncratic resources, to enable innovative approaches in planning. On the one hand, we are discussing spatially restrained urban plots, which have the capacity and need to be reset. On the other hand, each plot is a knot in the web of relations on a multiplicity of scales. The material city is nested into a set of interrelated scale levels – the plot, the quarter, the city, the region, potentially even the polycentric megacity region. The immaterial relations however span a multicity of scale levels. The challenge is to combine these two perspectives for their mutual benefit. The underlying processes are constitutive to urban space diversity, as urban form shapes urban life and vice versa.

This paper presents an English case of urban agriculture, the Edible Public Space Project in Leeds, contextualised in a context of urban agriculture initiatives committed to social-environmental justice, to the reproduction of common goods and the promotion of an urban planning which promotes the right to food and to the construction of urban space from the bottom up. The case study emerged as the result of action-research at the crossroads between urban planning policies, community work and critical geography. As opposed to many similar initiatives, the Edible Public Space Project is not intended merely as a temporary initiative hidden within the tiny folds of the city, but rather as an experiment which imagines and implements alternatives to current forms of urban planning within those folds and it contextualises them in the light of the ecological, fi nancial and social crisis of the last decade.
