Intersections of Jane Jacobs’ conditions for diversity and low-carbon urban systems: a look at four global cities

Countless cities are rapidly developing across the globe, pressing the need for clear urban planning and design recommendations geared towards sustainability. This article examines the intersections of Jane Jacobs’ four conditions for diversity with low-carbon and low-energy use urban systems in four cities around the world: Lyon (France), Chicago (United-States), Kolkata (India), and Singapore (Singapore). After reviewing Jacobs’ four conditions for diversity, we introduce the four cities and describe their historical development context. We then present a framework to study the cities along three dimensions: population and density, infrastructure development/use, and climate and landscape. These cities differ in many respects and their analysis is instructive for many other cities around the globe. Jacobs’ conditions are present in all of them, manifested in different ways and to varying degrees. Overall we find that the adoption of Jacobs' conditions seems to align well with concepts of low-carbon urban systems, with their focus on walkability, transit-oriented design, and more efficient land use (i.e., smaller unit sizes). Transportation sector emissions seems to demonstrate a stronger influence from the presence of Jacobs' conditions, while the link was less pronounced in the building sector. Kolkata, a low-income, developing world city, seems to possess many of Jacobs' conditions, while exhibiting low per capita emissions - maintaining both of these during its economic expansion will take careful consideration. Greenhouse gas mitigation, however, is inherently an in situ problem and the first task must therefore be to gain local knowledge of an area before developing strategies to lower its carbon footprint.

Listening to ‘Generation Jacobs’; A Case Study in Participative Engagement for a Child-Friendly City

This paper reflects on the enduring value of Jane Jacobs’ Life and Death of American Cities in the context of Child-Friendly Cities. This is explored through a project in Belfast which has engaged primary school children in how they understand their local environment. This shows that while children can effectively contribute to policy debates, there is a need to express this in a way that can be more effectively assimilated into planning debates. The paper reflects on this experience, suggesting that ‘Generation Jacobs’ could be used as a rhetorical device to frame children’s needs in a way that can be better understood by the planning profession.

Agitating for a design and regeneration agenda in a postconflict city: the case of Belfast

Introduction

Belfast has been a focus of academic attention for the last forty years with most interest centred on various aspects of ‘the Troubles’. Where there has been interest in the built environment, it has largely been about how the ‘security situation’ impacted directly on architecture and on the design and layout of social housing. This paper seeks to go beyond this to explore how the political- administrative culture of ‘the Troubles’ interacted with ‘normal’ market forces to shape the central area of the city, and to consider the responses of a recently formed activist group, known as the Forum for Alternative Belfast (hereafter referred to as the Forum). The paper is written by three of the directors of the Forum.1 Moreover, the empirical research presented here was undertaken by the Forum as part of a campaign to address issues relating to the design, layout and quality of Belfast’s built environment. In the longstanding tradition of participant observation working within an action-research paradigm, the participants have attempted to offer an account that is evidentially and purposefully selfcritical and reflective. It is of course recognised that while this approach offers many positive attributes, such as phenomenological access through immersion in the project, it also has the potential to bring compromise on research detachment and objectivity.2 To address the latter, the authors have attempted
to avoid polemical argument, and to support claims with primary or secondary research evidence. The authors also acknowledge that action-research has a chequered history; however, they would argue
that their approach is faithful to a concept that sees ‘research’ defined as understanding and ‘action’ defined as seeking change. The Forum’s very purpose is to seek change, but to do this requires evidence, collaboration and demonstration. And in this sense, it is a learning process for all participants, including the research activists, government officials, community organisations and students. The authors also recognise the complexity of factors that affect urban management and change, particularly in a city such as Belfast, which has had to cope with political violence for over thirty years. And they appreciate that in the context of conflict, governance is skewed to cope with political realities. Hamdi reminds us, however, that in practice there is an ‘important dialectic between top-down planning, with its formal and designed laws and structures, and bottom-up selforganizing collectivism—those “quantum and emergent systems” which Jane Jacobs argued long ago give cities their life and order.’3

Hospital-Colónia Rovisco Pais: um projeto de uma cidade ideal?

Este artigo decorre de um projeto de investigação intitulado “Hospital-Colónia Rovisco Pais: antropologia e história em contexto”, apoiado em 2005 pelo Instituto de Investigação Interdisciplinar da Universidade de Coimbra. Procurarei interrogar a associação estabelecida pelo médico português Fernando Bissaya Barreto (1886-1974) entre o falanstério, concebido por Charles Fourier (1772-1837) nos anos 20 e 30 do século XIX, e as suas propostas de construção de um Hospital-Asilo-Colónia para “alienados” e, posteriormente, para doentes com lepra, atualmente designada por doença de Hansen ou hanseníase, por referência ao médico norueguês Armauer Hansen (1841-1912), que em 1872 identificou o Mycrobacterium Leprae. O propósito será averiguar as possíveis relações entre algumas utopias modernas de cidades ideais que, segundo Jane Jacobs em Morte e Vida das Grandes Cidades, influenciaram o que ela designa por princípios do urbanismo moderno ortodoxo, baseados no que os urbanistas gostariam que as cidades fossem e não no que elas são, e algumas estruturas de isolamento, nomeadamente colónias agrícolas, construídas para todos aqueles que representavam uma ameaça à utopia de uma sociedade perfeita.

Kriminalitetens geografi : vardagsbrottslighetens spatiala fördelning i Borlänge

The aim of this thesis is to describe and analyze the geographical distribution of everyday criminality in the town of Borlänge during the year 2002 and to analyze which measures to be taken in the physical social planning to decrease this everyday criminality there. The term everyday criminality is here to be understood as those categories of crime that appear most frequently in the records of reports to the police every year. Here two kinds of crime have been in focus, thefts from cars and office burglary.In fulfilling this aim two main questions have been answered. The first one is how the everyday criminality was distributed geographically in the town of Borlänge during the year 2002. The second one is which measures to be taken in the physical social planning to decrease this everyday criminality in the town of Borlänge.In order to answer the first question a spatial autocorrelation analysis, Local Moran LISA has been used. This method is based on the measurement Moran´s I and shows the spatial autocorrelation for every single location. To answer the second question three different theories of crime prevention through environmental design have been studied and applied in the analysis. These are Jane Jacobs’ ideas about ”the living city”, Oscar Newman´s ideas about ”defensible space” and Ronald V. Clarke´s theories about crime prevention.The major conclusions that can be drawn from this thesis are that the risk of being exposed to thefts from cars, during the analyzed time period, was highest in Centrum and Hagalund and their surroundings. The lowest risk of being exposed to this type of crime was found in Domnarvet and Islingby, during the year 2002. The highest risk of being a victim of the crime office burglary was found in Hagalund and its surroundings and in the single area of Kvarnsveden. The corresponding lowest risk was found in Lergärdet and its surroundings and in Norra Backa and Kupolen. The measures that should be taken in order to decrease these types of criminality can be divided into overall changes and place-specific changes. When it comes to the crime thefts from cars a more attractive central business district, a better view of parking lots from nearby buildings, dividing of larger parking lot zones into smaller ones, migration of hidden parking lots and stronger access control to parking lots where problems with this kind of crime have occurred have been suggested as overall changes. The corresponding place-specific changes are to remove vegetation that is blocking the view, better lighting and to put up signs with information about increased risk of exposure to crime at parking lots with the most problems. To decrease the amount of office burglaries overall changes as to create a better view of the area from nearby surroundings, move bigger office compartments or divide them into smaller units, rebuild characteristic buildings and increase security by strengthening the access control to offices with these kinds of problems could be useful. Finally there are possibilities to decrease office burglary by using place-specific measures as surveillance cameras combined with signs containing information about these, high fences and better lighting around the buildings where a higher risk of being exposed to this kind of criminality is present.

The death and life of the great Australian suburb

Inspired by the approach to understanding, critiquing and rebuilding both planning and the urban environment that Jane Jacobs did so well in her Death and Life of Great American Cities, this paper begins with the personal experience of living in one suburban neighborhood in Melbourne, Victoria. Particular elements which make this both a positive and negative experience are then connected to the geographical, planning and urban studies literature to offer a broader context in which better suburbs can be planned, developed and activated.

Life-patterns on the periphery : a humanities base for development imperatives and their application in the Chicago city-region

Life-Patterns on the Periphery: A Humanities Base for Development Imperatives and their Application in the Chicago City-Region is informed by the need to bring diverse fields together in order to tackle issues related to the contemporary city-region. By honouring the long-term economic, social, political, and ecological imperatives that form the fabric of healthy, productive, sustainable communities, it becomes possible to setup political structures and citizen will to develop distinct places that result in the overlapping of citizen life patterns, setting the stage for citizen action and interaction. Based in humanities scholarship, the four imperatives act as checks on each other so that no one imperative is solely honoured in development. Informed by Heidegger, Arendt, deCerteau, Casey, and others, their foundation in the humanities underlines their importance, while at the same time creating a stage where all fields can contribute to actualizing this balance in practice. For this project, theoretical assistance has been greatly borrowed from architecture, planning theory, urban theory, and landscape urbanism, including scholarship from Saskia Sassen, John Friedmann, William Cronon, Jane Jacobs, Joel Garreau, Alan Berger, and many others. This project uses the Chicago city-region as a site, specifically the Interstate 80 and 88 corridors extending west from Chicago. Both transportation corridors are divided into study regions, providing the opportunity to examine a broad variety of population and development densities. Through observational research, a picture of each study region can be extrapolated, analyzed, and understood with respect to the four imperatives. This is put to use in this project by studying region-specific suggestions for future development moves, culminating in some universal steps that can be taken to develop stronger communities and set both the research site specifically and North American city-regions in general on a path towards healthy, productive, sustainable development.

New York: the revitalization of public space. Recent interventions in the Manhattan grid

La reticula de Nueva York ha sido un formato de nuevos planteamientos de "hacer ciudad" desde hace dos siglos. Esta ultima decada ha suspuesto un periodo fructifero para el espacio publico neoyorkino bajo la administracion de Michael Bloomerg. Esta revitalizacion no habria podido ser posible sin la reactivacion de factores de espacio publico que ya existian: la reticula, la legislacion publica y el rol del ciudadano. El ciudadano juega un papel fundamental en la ciudad, ya que es usuario, critico y promotor de espacio publico. Sin embargo, en ocasiones no es evidente para quien o quienes estan pensados los nuevos espacios publicos en la ciudad. Desde esta perspectiva, podemos identificar diferentes usuarios en la ciudad y analizar formulas recientes de espacio publico para cada uno de ellos: el vecino, el ciudadano, y el visitante. En palabras de Jane Jacobs: " las ciudades tienen la capacidad de proveer algo para todo el mundo, solo porque, y solo cuando, han sido proyectadas por todo el mundo".

Sense and sensibility by Jane Austen

It's the fact that it's Austen mentioned here that provokes a response. The broad cultural veneration of Jane Austen means that even those who have never read her work are likely to have a strong reaction to Emerson's famou quotation. It is worth considering Emerson's accustion befor teaching an Austen novel, as many of his assertions will be amde - albeit in different terms - byt twenty-first-century students.
