The urbanisation of cities increases the demands on, and complexity of, urban land use. Urban densification is challenging urban green space. Cities have responded to this challenge by adopting a multiple-use strategy where different functions share space. Shrinking open space has to contain solutions for everyday functions such as bicycle parking, waste sorting, blue-green stormwater systems, and playscapes. Values and functions that can reinforce and amplify each other are therefore of interest to study. The present article explores the possibilities for blue-green solutions (BGS) to be used as part of children’s playscapes. BGS are aboveground, ecological stormwater facilities, introduced to prevent flooding and support biodiversity while adding recreational and aesthetic qualities to the urban environment. The objective is to discuss the extent to which ecological and social values can reinforce each other in terms of encouraging children to engage with BGS natural elements. The researchers have studied the Augustenborg residential neighbourhood in Malmö. The area was primarily investigated through a postal survey, which identified a remodelled park with a floodable sunken lawn as a potentially attractive area for children’s activities. The park was analysed as a potential playscape and supported by on-site observations. The study shows that even if BGS largely meet children’s play values, due to existing socio-spatial structures, children are not using the offered play features. The article discusses the results in terms of how stormwater management may enhance the actualisation of play potentials in children’s everyday living environment.

Urban landscapes, structures and design features are associated with travel mode choice and have implications for sustainable living environments. The particular role of the built environment for children’s independent active mobility has received increasing attention in research and practice. However, the complexity of the transactions between person and environment needs to be understood with special focus on children’s use and experiences of the outdoor spaces in a neighborhood. This chapter discusses children’s independent active mobility as an ongoing transaction with the surrounding environment, continuously shifting between transport and play. The chapter synthesizes research on children’s outdoor play and active travel from the fields of environmental psychology, urban planning and landscape architecture. Four theoretical concepts compatible with a comprehensive understanding of children’s mobility in urban open spaces are presented: place attachment, affordances, wayfinding and prospect-refuge. The concepts are elaborated from a child perspective to highlight dimensions in the planning, design and management of outdoor spaces that can support children’s independent active mobility.

This paper adds to the relatively few European studies on the pedestrian friendliness of urban areas, and on transport walking. Using the Human Environment Interaction (HEI) model (Kuller, 1991), the study explores the associations between perceived neighbourhood spatialphysical and social environment qualities and walking to neighbourhood destinations, and examines whether these associations are mediated by the emotional relationship to the residential neighbourhood. One hundred and ten urban residents in the city of Malmo, Sweden, completed a web-based survey, including measurements of walking intentions and behaviours, and the short version of both the Perceived Residential Environment Quality Indicators (PREQIs) and the Neighbourhood Attachment Scale (NAS). Structural Equation Modeling revealed direct effects of individual factors and neighbourhood spatial-physical and social environmental qualities on transport walking. The effect of environmental qualities was partly mediated by participants' emotional relationship to the residential neighbourhood. Spatial-physical as well as social-relational features of the neighbourhood seem to play a role in walking intentions and behaviours, thereby emphasising the importance of considering both aspects in measures to support urban pedestrian friendliness.

This study investigates associations between perceived micro-level urban design qualities, the affective experience of walking, and intention to walk specific routes in the neighbourhood. A total of 106 residents assessed on-site three routes planned for walking in semi-central neighbourhoods. In the prediction of the residents’ intention to choose to walk and intention to avoid walking the route, perceived urban design qualities were mediated by the affective experience of valence of the walk. The perceived complexity and aesthetic quality, upkeep and order, and the presence of well-maintained greenery, were identified as important. These perceived urban design qualities and affective experiences varied between the three routes, but also within the routes. It is proposed that understanding of site-specific affective experience of walking environments could serve as guidance for urban design practices.

This study focuses on drivers for changing urban flood risk. We suggest a framework for guiding climate change adaptation action concerning flood risk and manageability in cities. The identified key drivers of changing flood hazard and vulnerability are used to provide an overview of each driver's impact on flood risk and manageability at the city level. We find that identified drivers for urban flood risk can be grouped in three different priority areas with different time horizon. The first group has high impact but is manageable at city level. Typical drivers in this group are related to the physical environment such as decreasing permeability and unresponsive engineering. The second group of drivers is represented by public awareness and individual willingness to participate and urbanization and urban sprawl. These drivers may be important and are manageable for the cities and they involve both short-term and long-term measures. The third group of drivers is related to policy and long-term changes. This group is represented by economic growth and increasing values at risk, climate change, and increasing complexity of society. They have all high impact but low manageability. Managing these drivers needs to be done in a longer time perspective, e.g., by developing long-term policies and exchange of ideas.

Walkability is often researched from the perspective of certain physical features in the built environment. However, for this paper, the point of departure was to also treat walking as a transport mode for reaching destinations and performing every-day activities. A conceptual model addressing both perceptions of the built environment and perceived limits due to every-day activities was used as a standpoint for examining walking behaviour among residents in three neighbourhoods in the city of Malmo, Sweden ( N =1001). A principal component analysis for the variables addressing the aspects of the model revealed a resemblance with our theoretical interpretation. The obtained components’ relationships with reported walking frequency were examined with binary logistic regression and revealed a significant association for the rating of one factor addressing the perceived limits on walking due to the constraints of every-day activities.

Urban flooding is of growing concern due to increasing densification of urban areas, changes in land use, and climate change. The traditional engineering approach to flooding is designing single-purpose drainage systems, dams, and levees. These methods, however, are known to increase the long-term flood risk and harm the riverine ecosystems in urban as well as rural areas. In the present paper, we depart from resilience theory and suggest a concept to improve urban flood resilience. We identify areas where contemporary challenges call for improved collaborative urban flood management. The concept emphasizes resiliency and achieved synergy between increased capacity to handle stormwater runoff and improved experiential and functional quality of the urban environments. We identify research needs as well as experiments for improved sustainable and resilient stormwater management namely, flexibility of stormwater systems, energy use reduction, efficient land use, priority of transport and socioeconomic nexus, climate change impact, securing critical infrastructure, and resolving questions regarding responsibilities.

It is a complex task to find optimal protective clothing to prevent the spread of Ebola virus disease (Martin-Moreno et al., 2014; Ryschon, 2014). The fear of getting infected is an obstacle for recruiting healthcare workers. In addition, the current design of protective clothing might curtail their working capacity severely in the hot and humid climate of West Africa and, in addition, paradoxically increase the risk of infection. Emergency work in full protective clothing including respiratory mask may lead to extreme heat stress in the hot climates resulting in shortened work time, dehydration, reduced professional judgement, and exhaustion. This increases risk of infection of health stuff (WHO, 2014). In Monrovia, Liberia, daytime maximum temperatures in the end of the year often reach 30–31°C, and the temperatures will be higher January to May, the hot season (Kjellstrom et al., 2014; http://climatechip.org/). In order to manage this heat stress, the workers need breaks (Kjellstrom et al., 2009). This leads to a frequent need to remove the protective gear, which involves an increased risk of infection. The multiple steps to remove the suit can take up to 30min (Kitamura, 2014). The modified Predicted Heat Strain (ISO 7933, 2004) model was used to indicate the expected work times (Fig. 1). The estimation was made based on the following assumptions. Standard man was chosen for the model calculations. Medium heavy activity (300W) was taken as the average work rate. The core temperature limit to cease such emergency work was set to 38.5°C. Three clothing types with different moisture permeability (i m) were selected for comparison: an impermeable outer layer (i m = 0.00), a semipermeable outer layer (i m = 0.07), and a relatively tight but still permeable outer layer (i m = 0.20). The basic clothing insulation in all cases was theoretically taken as 1 clo (0.155 m2K W−1) for comparative purposes. In all air temperature conditions, the other environmental factors were kept constant. Ambient water vapour pressure was set to 3.0 kPa, air velocity/body motion was 1 m s−1, and there was assumed no radiation effect present (work indoors or in shade). 1 Continuous work times for a work rate of 300W at different air temperatures before reaching a core temperature limit at 38.5°C in clothing with different moisture permeability (i m). The chosen work load in impermeable and semipermeable clothing allows 40min or shorter exposure during the hottest periods (Fig. 1) until the core temperature exceeds the suggested safe limit for occupational exposure. Higher core temperature is associated with decreased mental performance and increased misjudgement and mistakes (O’Neal and Bishop, 2010). Maximizing the moisture permeability and minimizing the clothing layers worn beneath the protective gear, provided that it should be resistant to penetration by body fluids, is a simple way of preventing heat stress and increasing the time spent inside the gear. However, dehydration and water intake must also be considered during extended exposures. A heat stress management program including rehydration should be an essential part of the overall health and safety program in any case. A desirable addition would be personal cooling used inside the protective clothing, such as cooling vests with ice or phase change materials (PCMs; Gao, 2014) or filtered ventilated coveralls (Kuklane et al., 2012). This may prolong working time to about 2h and reduce the number of gear changes per day. With 2-h work time in protective gear, the number of required personnel could be halved with possible decrease in contaminated waste. The final choice of the cooling method depends on specific air temperature and humidity. Increasing air temperature and, especially, humidity do reduce the effectiveness of air cooling and increase the benefits of PCM products. The use of PCMs requires freezers or cool areas for solidification after use. Cooling vests with ice are the cheapest and electricity for freezers is required. Power is one of the basic resources to provide healthcare and to cope with epidemics. Otherwise, the other types of PCM, e.g. Glauber’s salt or organic hydrocarbons/wax, with melting/solidifying temperature at about 28°C are available. For workers’ recovery after heat exposure, a room with air temperature below 27°C is recommended. The room or connected facilities could be used for PCM solidification storage. If still unavailable, then the melted PCM can be solidified in a relatively cooler water bath (using underground/well water, etc.), in an underground cave or in a cooler area during night. The higher the melting temperatures are, the less effective cooling is. However, if the temperature gradient is about 6°C or greater, the PCM can still provide a cooling effect. Considering cooling effect in ventilated garments, the provided air flow should be above 100 l min−1. There are filtered fan systems available on the market that manage the flows up to and above 200 l min−1 with the battery power lasting at least 5–8h (recharging takes about 2h). Ventilated systems (positive pressure suits) may allow even drinking water in the suit and that may prolong the work time even more. Table 1 gives a rough cost comparison of the present and a possible future protective clothing system based on 1-day (8-h) shift. It takes into account only the equipment cost. Estimation is based on the work time predictions given in Fig. 1 for the hottest work periods, i.e. 30min for the impermeable set and 2h for the new system that prolongs work period by higher permeability or by use of a cooling device. In both cases, similar final core temperatures are expected to limit the exposure. Also, it is expected that both sets take 30min for dressing, 30min for undressing, and require 30min for recovery between the work periods. As it can be seen the equipment cost of a new, theoretically even a 10 times more expensive solution is almost 3 times higher for a day. Table 1. Comparison of the equipment cost of the present and a possible, 10 times more expensive protective clothing system based on 1-day (8-h) shift. Assumed work time is 30min for present and 2h for the new system. In both cases, expected donning, doffing, ... Simultaneously, there are also other benefits with an actively cooling clothing system. The personnel need to cover one workstation is halved. The personnel have even extra time (about 30min) between the shifts to help with any other tasks or for additional recovery. Due to fewer times of dressing–undressing (16 + 16 times 30min versus 4 + 4 times 30min for present respective new system), there is also less need for assistance and disinfection during these periods. There will be less contaminated waste or fewer amounts of products to be cleaned. The new systems are meant to be reusable (extra costs for decontamination procedures have to be considered) compared to present, supposedly disposable systems, and already 2.5 times reuse will even up the equipment costs at the estimated prices. Infection risks are diminished due to the reduced need for undressing and cleaning procedures. In conclusion, reducing the risk of infection among the front-line healthcare workers and allowing a doubling of their work capacity could be a critical factor to successfully contain the epidemic. Considering that this epidemic is not the last, and with warmer climate both the epidemics are expected becoming more frequent, and conditions to fight them more severe (IPCC, 2013), then the testing and evaluation for selection of the optimal equipment is required long before missions are set out.

Background: Active travel has a potential to increase children’s physical activity (PA). Pedometers offer a valid option to measure PA, but do not capture cycling activity. Children’s self-reported cycling distances can be analyzed by the Geografic Information System (GIS). Aim: To combine pedometry and GIS mapping to identify the relative amount of cycling in children’s PA. Study group: Of all children in 4th grade (n=187) in Staffanstorp Sweden, 144 had valid pedometer data. Fifty-six children were non-cyclists while 88 children (32 boys, 47 girls, 9 gender unknown) reported at least one cycle journey. Methods: Cycle trips were entered into GIS and calculated to total cycling distance. Average length of the single distances cycled per day was 676 m (SD=534 m). A previously reported cycling speed (13.5 km/h) was used to calculate time spent cycling. Consequently distance=676 m, speed=13.5 km/h=13,500 m/3600 s=3.75 m/s and time=676m/3.75m/s=180.26 s=3 min. Expenditure of 4 and 5 metabolic equivalents (METs) has in children been reported equivalent to 122 and 127 steps/min, respectively. We estimated 4.7 METs (13.5 km/h) as 126 steps for every min of cycling (127–122=5×0.7=125.5). Results: The daily mean cycle distance was 676 m, on average 379 additional steps/day for cycling children (min. 21, max. 1385, SD=299) with no gender difference. Additional “steps” obtained by cycling corresponded to on average 3% of their PA. Conclusion: The relative contribution of cycling in 10-year-old children’s PA level is quite small and stable between children across different levels of activity levels, regardless of gender.
