Introduction: Infrastructural stigma and urban vulnerability

In this introduction to the Special Issue ‘Infrastructural Stigma and Urban Vulnerability’, we outline the need to join up debates on infrastructural exclusion on the one hand and urban stigma on the other. We argue that doing so will allow us to develop a better understanding of the co-constitutive relationship between the material and the symbolic structures of the city shaping urban exclusion and vulnerability. Positing that stigma is not merely a symbolic force but has significant material effects, we show how urban dwellers often experience it in deeply embodied ways, including through impacts on their physical health. Furthermore, stigma is not only imposed on the built environment through discourse, it also emanates from the materiality of the city; this agentic role of the city is often disregarded in sociologically-informed approaches to urban stigma. When infrastructures become sites of contestation about urban inclusion, stigma can be utilised by stigmatised residents to demand connection to public networks, and the wider symbolic inclusion this entails. Through examining the issue of infrastructural stigma in cities and urban territories across the Global North and Global South, as well as the places in between, the nine articles in this Special Issue pay attention to the global relationalities of infrastructural stigma. Ultimately, our focus on the infrastructural origins of stigma draws attention to the structural causes of urban inequality – a reality which is often occluded by both stigma itself and by prevalent academic approaches to understanding it.

A novel approach of creating sustainable urban planning solutions that optimise the local air quality and environmental equity in Helsinki, Finland: The CouSCOUS study protocol

Background Air pollution is one of the major environmental challenges cities worldwide face today. Planning healthy environments for all future populations, whilst considering the ongoing demand for urbanisation and provisions needed to combat climate change, remains a difficult task. Objective To combine artificial intelligence (AI), atmospheric and social sciences to provide urban planning solutions that optimise local air quality by applying novel methods and taking into consideration population structures and traffic flows. Methods We will use high-resolution spatial data and linked electronic population cohort for Helsinki Metropolitan Area (Finland) to model (a) population dynamics and urban inequality related to air pollution; (b) detailed aerosol dynamics, aerosol and gas-phase chemistry together with detailed flow characteristics; (c) high-resolution traffic flow addressing dynamical changes at the city environment, such as accidents, construction work and unexpected congestion. Finally, we will fuse the information resulting from these models into an optimal city planning model balancing air quality, comfort, accessibility and travelling efficiency.

Ridesourcing and urban inequality in Chicago: Connecting mobility disparities to unequal development, gentrification, and displacement

Ridesourcing advocates and companies promise many benefits to cities, such as increased accessibility, a solution to the last-mile transit problem, and even reduced need for automobiles. However, an important body of research has indicated that ridesourcing is more heavily used by more privileged consumers and in more affluent and whiter neighborhoods. Questions have also emerged about the effects of ridesourcing on public transportation. This study builds on a mobility disparities perspective by analyzing ridesourcing in the context of urban inequality, including gentrification and displacement. Using a large data set from the Chicago area, this study shows that ridesourcing is associated with areas that have seen rising rents and have become whiter and more educated. The results also show that ridesourcing is more prevalent in areas that are accessible by public transportation. Although the causal relationship between ridesourcing and gentrification is complex, the study suggests a new direction in the literature that embeds the analysis of ridesourcing in the broader frameworks of unequal urban development and neoliberalization. The study also suggests policy approaches that could help to reduce some of the connections between ridesourcing and urban inequity.

Entrepreneurship and the Promises of Inclusive Urban Development in Ethiopia

Ethiopia is one of the rapidly urbanizing countries in Africa and rural-urban migration is the major factor in the urbanization process. Migration is selective and rural youth are more likely to migrate to cities than others. However, the capacity of cities to accommodate the massive influx of migrants by providing formal employment is limited. Consequently, migrants remain marginalized and without access to employment opportunities. The majority are pushed into self-employment in the informal sector with few entrepreneurial skills and no access to affordable finance. Besides, though Ethiopia has shown economic growth, the challenges posed by a fast-growing young population has increased urban inequality, making the youth vulnerable. Despite such challenges, harnessing the benefits of the youth bulge and promoting inclusive development through the promotion of entrepreneurship has become a priority area since 1990s. Although improvements have been made, entrepreneurship programs are unable to reach the unemployed youth and those engaged in informal sector. The objective of this paper is to explore barriers that hinder the youth to formalize informal businesses and to start new businesses. The study followed a qualitative approach. Data were collected through key informant interviews and focus group discussions from four cities-Addis Ababa, Adama, Bahir Dar and Hawassa. The findings show that several bottlenecks including politicization of entrepreneurship, lack of understanding of the nature and demands of the youth; weak instructional systems; low levels of service capacity and inefficiency; lack of entrepreneurship education, youth negligence, and corruption hinder entrepreneurship programs and thereby attaining inclusive development in Ethiopia.

Neighbourhood selection and neighbourhood matching: Choices, outcomes and social distance

In this article, we ask how well Australian households are matched to their neighbourhood social environments. We broadly replicate a previous study of matching and ask to what extent households live in communities that are similar in socio-economic status to their characteristics. And, when households move, do they relocate in such a way as to increase similarity to their neighbours? The processes are at the heart of understanding the urban structure, how it changes over time and the links to urban inequality. The article uses data on household incomes from the Household, Income and Labour Dynamic (HILDA) Survey to measure the degree of similarity between households and their neighbours. We study the variation in matching for the population as a whole, and by quintiles of median neighbourhood income. We also measure how individuals that change neighbourhoods increase their similarity to the destination neighbourhood. We find that with respect to matching there is considerable diversity in the levels of matching; and that with respect to residential change, households in general do not make major shifts to increase matching when we control for housing tenure and other household characteristics. There is a need for further replications to understand the nature of matching and the outcomes.

Beyond a standardised urban lexicon: which vocabulary matters?

This epilogue reflects on the introduction and three papers of this special issue in order to highlight the issue’s contribution to the vital conversation of re-wording and re-theorising the urban. To further advance this conversation, we must recognise the very real imbalances of access to resources and power to influence that exist between the global North and global South, including resources to conduct research and power to publish journals. As our cities face multiple and urgent challenges such as the climate crisis, urban inequality, global pandemics and inadequate infrastructure, it is never too soon to re-think, to re-word and ultimately, to re-act the urban lexicon.
