Spatial differences in urban environmental conditions contribute to health inequalities within cities. The purpose of the paper is to map environmental inequalities relevant for health in the City of Dortmund, Germany, in order to identify needs for planning interventions. We develop suitable indicators for mapping socioeconomically-driven environmental inequalities at the neighborhood level based on published scientific evidence and inputs from local stakeholders. Relationships between socioeconomic and environmental indicators at the level of 170 neighborhoods were analyzed continuously with Spearman rank correlation coefficients and categorically applying chi-squared tests. Reclassified socioeconomic and environmental indicators were then mapped at the neighborhood level in order to determine multiple environmental burdens and hotspots of environmental inequalities related to health. Results show that the majority of environmental indicators correlate significantly, leading to multiple environmental burdens in specific neighborhoods. Some of these neighborhoods also have significantly larger proportions of inhabitants of a lower socioeconomic position indicating hotspots of environmental inequalities. Suitable planning interventions mainly comprise transport planning and green space management. In the conclusions, we discuss how the analysis can be used to improve state of the art planning instruments, such as clean air action planning or noise reduction planning towards the consideration of the vulnerability of the population.

Noise action planning according to the EU Environmental Noise Directive aims to improve people's health. Although health inequalities exist, the Directive does not address social inequalities in residential exposure to road traffic noise. In multivariate regression analyses based on two urban study populations, we assess the relationship between objective and subjective indicators of residential exposure to road traffic noise as an issue of environmental justice. Residential neighbourhood satisfaction, socio-demographic and -economic, health-related and noise-related attitudinal factors were included as covariates additionally explaining the subjective response to road traffic noise (noise annoyance). Our results underline the need to select, operationalise and examine noise-related indicators very carefully, as objective noise exposure predicts noise annoyance insufficiently. Otherwise, urban environmental planning might miss environmentally unjust situations and fail to initiate distributive and procedural environmental justice.

Urban residents’ need to be in control of their home environment can be constrained by perceived uncontrollability of exposure to road traffic noise. Noise annoyance may indicate a psychological stress reaction due to this uncontrollability perception, thereby undermining the restoration process. Environmental resources, such as having access to a quiet side at home and dwelling-related green, may reduce noise annoyance both directly by shielding acoustically and indirectly by enhancing residents’ perceived noise control. We assessed the potential mediating role of perceived noise control in independent and joint associations of road traffic noise exposure (>65 dB L_den) and of an absent dwelling-related environmental resource (three indicators concerning quiet sides and one indicator concerning dwelling-related green) with noise annoyance. In our cross-sectional, questionnaire-based study on elderly urban citizens (N = 1812), we observed a statistically significant indirect effect of noise exposure on noise annoyance through perceived noise control (39%, 95%CI 26–55%). Statistical mediation between indicators of absent environmental resources and noise annoyance was weaker. The potential indirect effect was confirmed for combinations of noise exposure with each of the four indicators of an absent environmental resource. Our findings may call for mitigating noise levels while fostering quietness and green at residents’ homes.

The transformation of cities towards healthy urban living environments for all is a challenge that needs to be addressed through collaboration of all relevant sectors in a transdisciplinary research processes. This paper reports on the design and showcase implementation of a methodological approach, named Interactive Spatial Understanding Support System (ISUSS), that is intended to support interactive knowledge co-production and integration among practitioners and researcher in a specific local context. The approach involves the combined use of interactive maps on a MapTable and a rich picture. The goal is to stimulate, articulate and map stakeholders’ knowledge on environmental health issues to come to a shared problem understanding. Drawing on the rich seam of data gathered over the reflexive engagement with the participants in Dortmund, Germany, we explored incidences of a transdisciplinary process. Findings suggest that the approach has the potential to encourage communication and social learning geared towards a shared understanding of the holistic problem situation. Whilst locally embedded spatial knowledge was shared using interactive maps on the MapTable, the rich picture elicited issues linked to wider geographical scale as well as non-spatial drivers. The paper concludes discussing research needs to further explore the approach among various other groups, including citizens.

Zusammenfassung: Städte werden durch verschiedene Merkmale charakterisiert, von denen Dichte ein aus gesundheitlicher Sicht besonders bedeutendes ist. Am Beispiel der Gesundheitsdeterminanten Lärm, Grün- und Freiflächen sowie gesundheitliche Versorgung wird dargestellt, dass Stadt als sich stetig verändernder Raum zu verstehen ist, der nur unter Beachtung der Wechselwirkungen seiner baulichen und sozialräumlichen Gestalt sowie gesellschaftlichen Gestaltung verstanden werden kann. Es werden verschiedene Stadttypen aufgezeigt und Leitbilder der Raum- und Stadtentwicklung aus gesundheitlicher Perspektive beschrieben. Eine Auseinandersetzung mit Instrumenten der Stadtentwicklung und des planerischen Umweltschutzes zeigt die Möglichkeiten zur Beeinflussung von Gesundheitsdeterminanten auf kommunaler Ebene auf. Partizipation von Öffentlichkeit und Stakeholdern spielt in lokalen Lebenswelten eine besondere Rolle. Der Beitrag zeigt auf, dass die Potenziale für eine gesundheitsfördernde Stadtentwicklung gegeben, aber vielfach noch nicht ausgeschöpft sind.
