Precarious spaces and urban change in post-conflict Belfast

The Northern Ireland conflict is shaped by an ethno-national contest between a minority Catholic/Nationalist/Republican population who broadly want to see the reunification of Ireland; and a majority Protestant/Unionist/Loyalist one, who mainly wish to maintain the sovereign connection with Britain. After nearly three decades of violence, which intensified segregation in schooling, labour markets and especially housing, a Peace Agreement was signed on Good Friday 1998. This paper is concerned with the peace process after the Agreement, not so much for the ambiguous political compromise, but for the way in which the city is constitutive of transformation and how Belfast in particular, is now embedded with a range of social instabilities and spatial contradictions. The Agreement encouraged rapid economic expansion, inward investment, especially in knowledge–intensive sectors and a short-lived optimism that markets and the neo-liberal fix would drive the post-conflict, post-industrial and post-political city. Capital would trump ethnicity and the economic uplift would bind citizens to a new expression of hope based on property speculation, tourism and global corporate investment.

Segregation unter Stagnationsbedingungen

Anlass der Untersuchung sind Verstärkungen von strukturwandel- und globalisierungsbedingten Wandlungen unter Schrumpfungs- und Stagnationsbedingungen. Denn Stagnations- und Schrumpfungstendenzen in einer Region sind selektiv, sie begünstigen über verschiedene Mechanismen Polarisierungen und Marginalisierungen: Die allgemeine Entspannung am Wohnungsmarkt hat erhöhte Mobilität und damit sozialräumliche Segregierungen und Polarisierungen der Wohnungsversorgung zur Folge. Leerstände und ausbleibende Investitionen begünstigen Polarisierungen von baulich-räumlichen Qualitäten. Diese beiden Entwicklungen überlagern sich im Stadtraum und verstärken sich gegenseitig. Dabei verbessert sich die Wohnungsversorgung in den benachteiligten Quartieren kaum, so die Ausgangshypothesen. Die Untersuchung fragt nach den Wirkungen des Nebeneinanders von Wachstums-, Stagnations- und Schrumpfungserscheinungen auf unterschiedlichen Maßstabsebenen, dem Zusammenspiel von sozialstrukturellen und qualitativen Veränderungen der baulich-räumlichen Gegebenheiten in den Quartieren sowie in innerstädtischer Differenzierung. Dabei interessieren besonders die Einflüsse eines regional entspannten Wohnungsmarktes und dessen Folgen für die Verwertungsstrategien im Wohnungsbestand auf Segregationsprozesse und die Wohnungsversorgung. Als Fallbeispiel der Untersuchung dient die Stadt Kassel. Der sozialräumliche Fokus liegt auf drei Typen benachteiligter Quartiere: Neben den in der aktuellen Diskussion zumeist betrachteten gründerzeitlichen Arbeiterquartieren und den Großsiedlungen der 1960/70er Jahre wurden auch die peripheren Geschosswohnungsbausiedlungen der 1950er/60er Jahre in die Untersuchung einbezogen, um den unterschiedlichen Rahmenbedingungen und Wirkungen in den Quartierstypen auf die Spur zu kommen und damit letztlich Grundlagen für stadtentwicklungspolitische Strategien zu erarbeiten. Die kleinräumigen Analysen von sozialräumlicher und baulich-räumlicher Struktur sowie zur Wohnungsversorgung deckten Parallelen und gegenläufige Entwicklungen zwischen den unterschiedlichen Quartierstypen auf; es ergaben sich verschiedene Anhaltspunkte zur Erhärtung der Ausgangsthesen. So wurde z.B. deutlich, dass sich unter den Marktbedingungen stagnierender Städte die Wohnflächenversorgung in den benachteiligten Quartieren kaum verbessert. Hierin zeigt sich ein entscheidender Unterschied zu stark schrumpfenden Städten, in denen sich die Versorgungslage (fast) durchgängig verbessert. Wohnungsmarktbarrieren wirken offensichtlich unter Stagnationsbedingungen für bestimmte Bevölkerungsgruppen weiter. Da sich ihre Wirkung aber für weitere Kreise der Bevölkerung abschwächt, verschärfen sich sozialräumliche Konzentrationen. Vor allem aber wurden Überlagerung und gegenseitige Verstärkung dieser sozialräumlichen mit baulich-räumlichen Polarisierungen deutlich, die vor allem aus stadträumlich konzentrierten Investitionen in den Gebäude- und Wohnungsbestand resultieren. Letztlich zeigt sich damit, dass regulierende Eingriffe nicht nur im Rahmen des Umbaus und der Erneuerung der Quartiere erforderlich sind, sondern insbesondere auch in den Wohnungsmarkt und dies auch bei entspannter regionaler Marktlage. Andernfalls ist weder eine angemessene Wohnungsversorgung aller Bevölkerungsgruppen noch der Zusammenhalt der Stadt(Gesellschaft) zu gewährleisten. Dabei ist die Stadtpolitik permanent mit der Gleichzeitigkeit von (wirtschaftlicher) Standortpolitik und sozialer Stadtentwicklung konfrontiert, die sie im Sinne einer nachhaltigen Entwicklung gegeneinander und miteinander abwägen muss.

The incidents of housing policies in the process of nesting the urban space (Buenos Aires, 1870-1999)

This article describes the housing policies displayed historically in B.A. that affected the processes of configuration and of giving hierarchy to the urban space. Since the process of modernization of B.A., at the end of the XIXth century, housing measures, urbanistic projects and political decisions have influenced the building of the city and the space distribution of their inhabitants: in this way, they have integrated some people and excluded others. No wonder, that, historically, popular sectors have established themselves in the South of the city (and in outskirt villages). These zones have been disregarded by the state, which has invested less in these areas. We will see how the connection between state housing policies and the population redistribution in the city, confirms the persistence of a strong process of urban and residential segregation that tends to expel the inhabitants of popular sectors and to attract the ones of the middle-class and high class sectors.

Sustainable urban criteria in the urban periphery of Guadalajara

The study of the growth of large cities, in the urban periphery or the peri-urban areas specifically, it relates to environmental degradation due to urbanization, if it is estimated that since 2008 more than half of the world population living in urban areas, this sector is affected as it presents overcrowding, segregation and deterioration of physical conditions, which will impact on the social aspects within localities. This great urban growth has usually developed with the lack of environmental planning.So it is necessary to include urban development, guidelines towards environmental conservation and rehabilitation of the territory. The future of cities will depend largely on the actions taken now. As urban development inevitably requires planning urban settlements through sustainable development so as to provide alternative technologies, based on the reality of Latin American countries.In the peripheral area of the Metropolitan Zone of Guadalajara, is taken as a case study of the town of La Venta del Astillero, which by its nature allows access and functionality to develop a set of criteria and indicators to urban sustainability, which can take as a model for other communities in the urban periphery.

Overcoming Gender Disadvantages. Social Policy Analysis of urban middle-class women in Colombia

The World Bank Report 2012 starts with this statement: “Gender equality matters in itself andit matters for development because, in today’s globalized worlds, countries that use the skillsand talents of their women would have an advantage over those which do not use it.” With theframe that suggest that gender equality matters, this paper describes some policy alternativesoriented to overcome gender disadvantages in the formal labor market incorporation of theurban middle class women in Colombia. On balance, the final recommendation suggest that itis desirable to adopt policy alternatives as Community Centers, which are programs orientedto a social redistribution of the domestic work as a way to encourage women participationin the formal labor market with the social support of the members of their own community.The problem that the social policy needs to address is the segregation of women in the formallabor market in Colombia. Although the evidence shows that the women overcome theeducational gap by showing better performance in education that their male peers, womenare still segregated of the labor market. The persistence of high rates of unemployment on thefemale population, the prevalence of the informal labor market as a women labor market, andthe presence of the payment difference between men and women with similar professionaltrainings are circumstances that sustain the segregation statement. These circumstances areinefficient for the society because an economic analysis shows that the cost of maintain the statuquo is externalized in the social security system that includes health, pension and maternityleave regimens. Therefore, the women segregation involves a market failure.This paper evaluates five policy alternatives each directed to the progress of a different causaldimension of the problem: (i) Quotas in the private market, (ii) Flexible working hours,(iii) replace the maternity leave with a family leave, (iv) Increase the Community Centers forredistributing the care work, and (v) Equal payment enforcement. The first alternative looksto increase women’s participation in the formal labor market. The second, third, and fourthalternatives constitute a package addressed at redistributing care work by reducing women’sresponsibility for reproductive work in the household with the help of husbands and the localgovernment. The fifth alternative intervenes to resolve the equal payment problem.After a four criteria evaluation that measure effectiveness, robustness and improbability inimplementation, efficiency and political acceptability or social opposition, the strongest alternativeis the fostering of Community Centers that promote a redistribution of care work. Thispolicy performs well in the assessment process because it combines gender focus with importantindirect effects: child support and human capabilities. The policy also shows a bottomup implementation process that overcomes the main adoption difficulties in the gender focusprograms and is supported by strong evidence of success in the Colombian context; this evidenceis produced by both transnational actors as a World Bank and also in local accountabilityreporters executed by local institutions like Colombian Institute of Family Welfare (ICBF).

Social Networks, Segregation and Poverty in Sao Paulo

The associations between segregation and urban poverty have been intensely scrutinized by the sociology and urban studies literatures. More recently, several studies have emphasized the importance of social networks for living conditions. Yet relatively few studies have tested the precise effects of social networks, and fewer still have focused on the joint effects of residential segregation and social networks on living conditions. This article explores the associations between networks, segregation and some of the most important dimensions of access to goods and services obtained in markets: escaping from social precariousness and obtaining monetary income. It is based on a study of the personal networks of 209 individuals living in situations of poverty in seven locales in the metropolitan area of Sao Paulo. Using network analysis and multivariate techniques, I show that relational settings strongly influence the access individuals have to markets, leading some individuals into worse living conditions and poverty. At the same time, although segregation plays an important role in poverty, its effects tend to be mediated by the networks in which individuals are embedded. Networks in this sense may enhance or mitigate the effects of isolation produced by space.

Responses to racial segregation in a black Miami community

The present study examines the extent to which blacks are segregated in the suburban community of Coconut Grove, Florida. Hypersegregation, or the general tendency for blacks and whites to live apart, was examined in terms of four distinct dimensions: evenness, exposure, clustering, and concentration. Together, these dimensions define the geographic traits of the target area. Alone these indices can not capture the multi-dimensional levels of segregation and, therefore, by themselves underestimate the severity of segregation and isolation in this community. This study takes a contemporary view of segregation in a Dade County community to see if segregation is the catalyst to the sometime cited violent response of blacks. This study yields results that support the information in the literature review and the thesis research questions sections namely, that the blacks within the Grove do respond violently to the negative effects that racial segregation causes. This thesis is unique in two ways. It examines segregation in a suburban environment rather than an urban inner city, and it presents a responsive analysis of the individuals studied, rather than relying only on demographic and statistical data. ^

Shopping for schools or shopping for peers : public schools and catchment area segregation

Market theory positions the consumer as a rational choice actor, making informed schooling choices on the basis of ‘hard’ evidence of relative school effectiveness. Yet there are concerns that parents simply choose schools based on socio-demographic characteristics, thus leading to greater social segregation and undercutting the potential of choice to drive quality improvements. In this paper we explore segregation by examining catchment areas for a range of public high schools in a specific middle-class urban area. We focus on socio-demographic characteristics, including levels of income, country of birth and religion affiliation, in order to explore residential segregation according to public high school catchment areas. Our data suggests distinct residential segregation between catchment areas for each public school within our dataset, particularly for the schools deemed to be popular and rejected, that may pose risks for broader equity concerns. We argue that, in contrast to market theory, even more affluent and active choosers are not equipped with information on the programmatic quality of their different school options, but instead may be relying on socio-demographic characteristics of schools—through surrogate information about the urban spaces that the schools occupy—in order to choose peer groups, if not programs, for their children.

Air pollution levels measured at traffic hot spots : Brisbane urban corridor study

Air pollution levels were monitored continuously over a period of 4 weeks at four sampling sites along a busy urban corridor in Brisbane. The selected sites were representative of industrial and residential types of urban environment affected by vehicular traffic emissions. The concentration levels of submicrometer particle number, PM2.5, PM10, CO, and NOx were measured 5-10 meters from the road. Meteorological parameters and traffic flow rates were also monitored. The data were analysed in terms of the relationship between monitored pollutants and existing ambient air quality standards. The results indicate that the concentration levels of all pollutants exceeded the ambient air background levels, in certain cases by up to an order of magnitude. While the 24-hr average concentration levels did not exceed the standard, estimates for the annual averages were close to, or even higher than the annual standard levels.

How can land and urban development make houses healthier?

Traditionally, the main focus of the professional community involved with indoor air quality has been indoor pollution sources, preventing or reducing their emissions, as well as lowering the impact of the sources by replacing the polluted indoor air with "fresh" outdoor air. However, urban outdoor air cannot often be considered "fresh", as it contains high concentrations of pollutants emitted from motor vehicles - the main outdoor pollution sources in cities. Evidence from epidemiological studies conducted worldwide demonstrates that outdoor air quality has considerable effects on human health, despite the fact that people spend the majority of their time indoors. This is because pollution from outdoors penetrates indoors and becomes a major constituent of indoor pollution. Urban land and transport development has significant impact on the overall air quality of the urban airshed as well as the pollution concentration in the vicinity of high-density traffic areas. Therefore, an overall improvement in indoor air quality would be achieved by lowering urban airshed pollution, as well as by lowering the impact of the hot spots on indoor air. This paper explores the elements of urban land and vehicle transport developments, their impact on global and local air quality, and how the science of outdoor pollution generation and transport in the air could be utilized in urban development towards lowering indoor air pollution.
