Urban research − understanding urban change in its diversity

ILS researchers Hannah Brill, Nils Hans and Isabel Ramos Lobato published an article, in collaboration with Norma Schemschat, Heike Hanhörster and Lara Hartig, in the journal Urban Planning. Building on growing research on changing geographies of migration and “new” arrival destinations, the article examines neighbourhoods across Germany through the lens of “left-behindness.” Drawing on 90 interviews from eight arrival neighbourhoods, the article analyses how “left-behindness” and the arrival of migrants interact in everyday life and local governance. It shows how structural constraints, symbolic representations, and social dynamics reinforce one another, shaping both the challenges and possibilities of migration. The article argues that left-behindness is best understood not as a spatial category but as a relational and processual condition that highlights uneven development and reveals how the challenges of migration-related diversity are locally negotiated and contested. https://doi.org/10.17645/up.11159.

Dr. Lea Fischer und Dr. Michael Kolocek haben einen Fachaufsatz veröffentlicht, in dem sie Ergebnisse aus dem Forschungsprojekt MaBIs (Marginalisierte Bevölkerungsgruppen und die solidarische Innenstadt) präsentieren. Aus einer raumwissenschaftlichen Perspektive diskutieren sie verschiedene Dimensionen informeller Arbeitstätigkeiten, etwa den Verkauf von Straßenmagazinen, das Betteln oder das Pfandsammeln. Der Aufsatz ist einer von über 40 Beiträgen in dem mehr als 800 Seiten umfassenden Sammelband von Frank Sowa und seinem Herausgeber*innenteam. Aus unterschiedlichen Perspektiven widmen sich die Autorinnen und Autoren den Lebenswirklichkeiten von Menschen, die in fragilen Behausungen leben. Der Band ist Open Access erhältlich. Mehr…

ILS researcher Bastian Heider, together with Stefan Siedentop from TU Dortmund University, has published an article in the journal Planning, Practice and Research. This paper examines the displacement of craft businesses from inner-city areas in five cities in North Rhine-Westphalia, Germany. Drawing on expert interviews with representatives from urban planning, economic development, and chambers of crafts, it identifies a complex interplay of highly context-related factors driving this process – ranging from land-use conversion and rising property values to emission conflicts and limited expansion opportunities. Urban policies have often tolerated or indirectly facilitated the marginalization of the craft sector. Recent planning initiatives show growing awareness of the issue, offering prospects for safeguarding productive uses and preserving mixed-use urban structures that are central to sustainable and resilient city economies. https://doi.org/10.1080/02697459.2026.2668492.  Further current publications can be found here.

Urban agriculture (UA) is frequently promoted as a pathway to improve urban sustainability, food security, and resilience, yet cross-city evidence on its scalable, system-wide impacts remains limited and methodologically inconsistent. We assess the theoretical scaling potential and food–energy–water (FEW) metabolism implications of expanding low-tech UA across five Global North cities, —London, New York City, Paris, Dortmund, and Gorzów Wielkopolski—using a harmonized two-part framework. The results provide a transferable, cross-city methodology and identify policy-relevant leverage points—especially enabling home gardening, securing land tenure, supporting new farmers or gardeners, and pairing expansion with composting and water-harvesting practices—to design context-sensitive UA scaling strategies. https://authors.elsevier.com/c/1muYocUG5e8ki.

Janina Welsch and Frederic Rudolph from the T3 Transportation Think Tank, have jointly published an article in the journal “Active Travel Studies: An Interdisciplinary Journal.” The study examines company bikes, which can form part of employers’ mobility management and cycling promotion schemes. However, it has been unclear, whether and to what extent they influence actual bicycle usage. The results show, that company bikes are a significant positive factor for commuting by bicycle. However, compared to the lowest usage frequence, this applies only to the middle category and not to the highest. A “company bicycle effect” is also not directly detectable in everyday cycling. However, indirect effects can be assumed. The majority of company bikies are e-bikes, and these show a significant positive association with both cycling to work and in everyday cycling. Particularly in view of the current rise in petrol and diesel prices, the bicycle could become an increasingly attractive alternative for many employees for short and medium distances. Here, the company bike provides employers with an effective tool to promote more sustainable commuting. https://doi.org/10.16997/ats.1774. Further current publications can be found here. here.
