Christmas tale of (un)sustainability: reflecting on consumption and environmental awareness on the streets of Amsterdam

In reflecting on Dutch Christmas shoppers, this article will discuss environmental Kuznets curve (EKC), postmaterialist values hypothesis, and ecological modernization theory. According to the EKC hypothesis, while at the initial stages of industrialization material resources are often used unsustainably, continuing industrialization leads to a threshold after which lead to progressively more sustainable technologies. According to the postmaterialist values hypothesis, only wealthier societies can ‘afford’ to care about the environment, assuming that wealth will lead to development of greater concern about and valuation of environment. Finally, ecological modernization theory postulates that environmental conditions improve with advanced technological development and suggests that enlightened self-interest, economy and ecology can be favourably combined and that productive use of natural resources can be a source of future growth. In generalizing economic, political and social trends in relation to consumption in The Netherlands, the aim of this article is to consider the consequences of Western-style consumption for the enterprise of global development. https://doi.org/10.1016/j.scs.2013.05.004 https://www.linkedin.com/in/helenkopnina/

Eye-tracking street users' visual exploration of buildings across the Western World

People in western countries spend approximately 90% of their time indoors. This severely affects their health (WHO 2013; Klepeis et al. 2001). The health risks are exacerbated if people travel between indoor spaces by car or public transport. Buildings on streets specifically designed to create a human scale and connected with the street-space can potentially invite people to walk and enhance their engagement with their surroundings (O’Mara 2019; Ewing et al. 2013). Since the 1960s, influential empirical studies have raised awareness of the walkability of streets (e.g. Jacobs 2008) but reliable evidence on the effectiveness of applied design solutions remains scarce (Spanjar & Suurenbroek 2020). This eye-tracking study focused on the visual ‘scanning’ of streetscapes and people’s appreciation of applied design principles. The aim was to gather together lessons learned from a variety of streetscapes in cities around the world and use them to inform the design of new developments in the Netherlands. Google Street View was used to select 19 images of streets in high-density environments with human-scale attributes in their façades and street-spaces. They were presented in a randomized order in a laboratory setting to 40 participants, who viewed them for 5 seconds. The participants’ visual explorative behaviour was recorded with advanced eye-tracking technology. A survey recorded their overall appreciation of the scenes and mouse-tracking collated their specific areas of interest (see fig. 1). The comparative analysis of the participants’ aggregated eye-fixation images together with the supplementary methods suggests that certain attributes for creating a human scale catch the eye in the first few seconds and are highly appreciated. These include the variety of a street’s façades, a street’s enclosedness, and the level of detail in the transition zone between the private ground floor and the public street (see fig. 2). Green features are particularly valued and might have important restorative qualities for people who spend most of their time indoors (Kaplan 1995; Ulrich 1984). Future research should focus on the design of façades and the street-space itself, taking people’s indoor lives and related stress levels as a starting point.

Optimizing urban green design for restorative effects in residential streets

The climate is right up your street

This book of examples suggests a variety of options for easy and accessible climate-resilient retrofitting of residential areas. The case studies for a set of common streets in the Netherlands will match urban settings in other countries. The examples show that effective climate-resilient retrofitting is usually quite simple and does not necessarily incur higher costs than traditional approaches, particularly in flat areas. An examination of typical Dutch urban street designs shows how climate resilience can be incorporated under different conditions while keeping costs down with retrofitting. We have investigated the effects of four retrofitting variants and specified their cost and benefits, applying a typology of common residential street characteristics. We sincerely hope these case studies inspire you to get started in your own town, city and country, because the climate is right up your street.

Liveable streets in Hanoi: a principal component analysis

Liveability along four streets in Hanoi, Vietnam is assessed. Hanoi is a rapidly growing metropolis characterised by high levels of personal motorized traffic. Two high traffic volume streets and two low traffic volume streets were studied using a mixed methods approach, combining the collection and analysis of quantitative and qualitative data on traffic volumes and liveability perceptions of its residents. The research methodology for this study revisits part of the well-known Liveable Streets study for San Francisco by Appleyard et al. (1981). A Principal Component Analysis (PCA) shows that residents on both low traffic volume streets experience less traffic hazard and stress, including noise and air pollution, than neighbouring high traffic volume streets. In line with Appleyard, the study shows that low traffic volume streets were rated more liveable than high traffic volume streets. In contrast to Appleyard, however, the study also shows that traffic volumes are not correlated with social interaction, feeling of privacy and sense of home, which is likely caused by the high levels of collectivism typical for Vietnam. Finally, the study indicates a strong residential neighbourhood type dissonance, where a mismatch exists between preferences for living in peaceful and quiet streets and the actual home location of residents.
