Evaluating spatial inequalities using a single walking accessibility measure is quite challenging. In response, the paper proposes combining two accessibility measures (real and potential) to provide additional insights into the identification and mapping of spatial inequalities. The municipality of Getafe in the Madrid Metropolitan Area, Spain serves as a case study. A questionnaire, administered via face-to-face interviews, recorded the resident’s walking preferences for reaching in-store retail. A gravity-based model was used to calculate real and potential accessibilities, which were combined to map four accessibility places that originate spatial inequalities: advantageous, moderately advantageous, moderately disadvantageous, and disadvantageous. The results suggest that potential accessibility values are higher than real accessibility values, and the final map shows the city centre residents (mostly seniors) benefit from the advantageous accessibility places. Disadvantageous places are mainly found in the city’s periphery, where younger people live.
Introduction: Researchers experience increasing pressures to connect with bodies that finance their projects. In this climate, critical scholars face many obstacles as they seek to navigate the treacherous waters of securing external funds. To debate these challenges, the ACME Editorial Collective organized a panel for the 2009 Annual Meeting of the Association of American Geographers in Las Vegas. This intervention represents a follow-up discussion and collective writing process among some of the panelists and members of the audience who attended the panel.
Below, we examine the neoliberalization of the current funding systems, discuss the implications for research practice, and make suggestions for critical engagement and transformation. Our suggestions, however, will not be easy to implement, as we can infer from the experience of the radical scholars of the post-1968 generation whose ascension into the upper echelons of North American and European university systems was also associated with the neoliberalization of the funding systems. This intervention represents a modest contribution in the tradition of critical research practice of creating the possibilities for progressive change.
Critical perspectives have become more visible in German human geography. Drawing on an analysis of the debate around the German reader "Kulturgeographie" published in 2003, we suggest that this case provides new insights into the "geography of critical geography". We briefly discuss the history of critical geography in Germany, leading to a comparison of the conditions of critical geography around 1980 and in recent years. The focus is on two factors in the changed role of critical perspectives in German geography: (1) the growing internationalisation of German geography, which opened new avenues and allowed new approaches to enter the discipline; and (2) the high citation indices of "critical" journals, which leads to an enhanced reputation and a high significance of international critical geography in the German discipline. However, we draw an ambiguous conclusion: the increased role of critical approaches in German geography is linked to a growing neoliberalisation of academia and a decline of critical approaches in other disciplines.

In the aftermath of an increasing integration of property and financial markets, the real estate industry is subject to soaring internationalization processes. Since international institutional investors appeared, transnational real estate investments have increased tremendously. In recent years, Central and Eastern European countries have been becoming more attractive to institutional investors and are therefore being integrated into international market structures. Within these countries, Warsaw emerged as the most dynamic and important real estate market. But what are the mechanisms and practices through which the real estate market of Warsaw becomes international? Which networks, intermediaries and frames are necessary to constitute a mature real estate market? The article argues that international real estate consultants are playing a crucial role in the underlying internationalization process. They are acting at the interface between investors, developers, construction companies and tenants and are therefore becoming a crucial hinge between real estate actors. With the example of the Warsaw real estate market we argue that international real estate consultancies are key drivers of the transformation process from a local to a global market. They transfer global knowledge, competence and practices and implement transparent and professional structures in the emerging Warsaw real estate market.
Refugee reception in Germany is a primarily municipal task that relies heavily on neighborhood-based volunteering. This paper asserts that there are fundamental spatial mismatches between municipal policies and neighborhood-based approaches that place additional burden on all of the stakeholders involved. Drawing from the case of Frankfurt-Rödelheim, which is a socially and ethnically mixed neighborhood in Frankfurt am Main, I show how the way the municipality accommodates refugees disregards the politically embraced work of neighborhood-based volunteers and how the ideal of neighborhood-based inclusion creates a spatial fetish that fails the living reality of the refugees. The findings are based on my ethnographic fieldwork as volunteer in a neighborhood-based welcome initiative.
In order to encourage a shift from the car to the more sustainable transport mode of cycling, cycle streets have been implemented in cities all over the world in the last few years. In these shared streets, the entire carriageway is designated for cyclists, while motorized traffic is subordinated. However, evidence on the impact of cycle street interventions related to travel behavior change has been limited until now. Therefore, the objective of this study was to evaluate whether cycle streets are an effective measure to facilitate bicycle use and discourage car use, thus contributing to the aim of promoting sustainable travel. For this purpose, we conducted a written household survey in the German city of Offenbach am Main involving participants affected by a cycle street intervention (n = 701). Based on two stage models of self-regulated behavioral change (SSBC), we identified the participants’ level of willingness to use a bicycle frequently and to reduce car use. By means of bivariate and multivariate statistical methods, we analyzed the influence of awareness, use, and perceptions of the cycle street on the willingness to change behavior towards more sustainable travel. The results show that the intervention has a positive impact on frequent bicycle use, while we observed only a limited effect on car use reduction. Traffic conflicts and car speeding within the cycle street adversely affect the acceptance of the intervention. The study’s findings provide new insights into the actual effects of a cycle street and its potential to encourage sustainable travel behavior.

Abstract
To promote non-motorised travel, many travel behaviour studies acknowledge the importance of the built environment to modal choice, for example with its density or mix of uses. From a mobility design theory perspective, however, objects and environments affect human perceptions, assessments and behaviour in at least three different ways: by their practical, aesthetic and emblematic functions. This review of existing evidence will argue that travel behaviour research has so far mainly focused on the practical function of the built environment. For that purpose, we systematically identified 56 relevant studies on the impacts of the built environment on non-motorised travel behaviour in the Web of Science database. The focus of research on the practical design function primary involves land use distribution, street network connectivity and the presence of walking and cycling facilities. Only a small number of papers address the aesthetic and emblematic functions. These show that the perceived attractiveness of an environment and evoked feelings of traffic safety increase the likelihood of walking and cycling. However, from a mobility design perspective, the results of the review indicate a gap regarding comprehensive research on the effects of the aesthetic and emblematic functions of the built environment. Further research involving these functions might contribute to a better understanding of how to promote non-motorised travel more effectively. Moreover, limitations related to survey techniques, regional distribution and the comparability of results were identified.
Highlights
- Cost-free ticket increases public transport use even when the share was high beforehand
- Free tickets are more effective than just a price reduction (zero-price effect)
- Low income, female and older employees benefit the most
- Not only travel behaviour but also attitudes change
- Cost-free public transport is one component in a set of travel demand management tools
Abstract
To increase its attractiveness for employees, to save costs regarding parking supply and to foster modal shift away from the car, employers can offer sharply cost-reduced public transport tickets. In the state of Hesse/Germany, public authorities have gone one step further by introducing a cost-free public transport ticket for all state employees. We argue that the step from sharply cost-reduced to cost-free is more than just a monetary difference. The aim of this study is to assess whether the ticket is actually affecting employees and what changed their travel behaviour. Therefore, we have analysed a two-wave survey conducted at Goethe University in Frankfurt: one from before and one from after the introduction of the new ticket. The results show a substantial increase in the use of public transport (pt) for commuting and other trip purposes. Car use and availability, however, did not decrease. In particular, those who had no cost-reduced jobticket beforehand switched to public transport after the introduction. Furthermore, we identified increasing public transport use for low-income employees (inclusion hypothesis) and several indicators pointing towards a more multimodal behaviour (multimodal hypothesis).
Non-forest ecosystems, dominated by shrubs, grasses and herbaceous plants, provide ecosystem services including carbon sequestration and forage for grazing, and are highly sensitive to climatic changes. Yet these ecosystems are poorly represented in remotely sensed biomass products and are undersampled by in situ monitoring. Current global change threats emphasize the need for new tools to capture biomass change in non-forest ecosystems at appropriate scales. Here we developed and deployed a new protocol for photogrammetric height using unoccupied aerial vehicle (UAV) images to test its capability for delivering standardized measurements of biomass across a globally distributed field experiment. We assessed whether canopy height inferred from UAV photogrammetry allows the prediction of aboveground biomass (AGB) across low-stature plant species by conducting 38 photogrammetric surveys over 741 harvested plots to sample 50 species. We found mean canopy height was strongly predictive of AGB across species, with a median adjusted R2 of 0.87 (ranging from 0.46 to 0.99) and median prediction error from leave-one-out cross-validation of 3.9%. Biomass per-unit-of-height was similar within but different among, plant functional types. We found that photogrammetric reconstructions of canopy height were sensitive to wind speed but not sun elevation during surveys. We demonstrated that our photogrammetric approach produced generalizable measurements across growth forms and environmental settings and yielded accuracies as good as those obtained from in situ approaches. We demonstrate that using a standardized approach for UAV photogrammetry can deliver accurate AGB estimates across a wide range of dynamic and heterogeneous ecosystems. Many academic and land management institutions have the technical capacity to deploy these approaches over extents of 1–10 ha−1. Photogrammetric approaches could provide much-needed information required to calibrate and validate the vegetation models and satellite-derived biomass products that are essential to understand vulnerable and understudied non-forested ecosystems around the globe.
