Association between early life exposure to agriculture, biodiversity, and green space and risk of inflammatory bowel disease: a population-based cohort study.

Background: Specific pollutants and environmental exposures are implicated in modulating inflammatory bowel disease (IBD) risk. However, the role of environmental exposures, particularly during the early life period, towards IBD risk, has not been systematically evaluated. Methods: We conducted a nationwide population-based cohort study during the study period extending from January 1, 1995, to September 1, 2020, using cross-linked Danish registers, maps, and inventories to ascertain the impact of agricultural land use, biodiversity, green space, urban space, blue space, and normalized difference vegetation index during pregnancy and the first two years of life on IBD, Crohn's disease (CD), and ulcerative colitis (UC) risk, using adjusted Cox proportional hazards regression analyses. We adjusted for covariates sex, maternal age at delivery, calendar year of birth, municipal-level socioeconomic status, and first-degree relative with IBD. Findings: Of 1,438,487 individuals included in the study who were followed from age 2 years until a median (IQR) age of 14 (8-20) years, 3768 individuals were diagnosed with IBD. Exposure to the second, third and highest quartiles of agriculture land use during early life, relative to the lowest quartile, were associated with increased CD risk (aHR 1.12, 95% CI 1.01, 1.26, 1.19, 95% CI 1.05, 1.34 and, 1.24 95% CI 1.06, 1.46, respectively). There was no association of agriculture land use with UC risk. Conversely, exposure to the third quartile of biodiversity in early life, compared to the lowest quartile, were associated with a lower CD risk (aHR 0.86, 95% CI 0.75, 0.98). A protective effect of greenspace was noted in the highest quartile for CD (aHR 0.87, 95% CI 0.78, 0.98). Interpretation: In a nationwide cohort with long-term follow up data, early life environmental exposures were associated with modulation of CD risk, with a harmful effect of agriculture land use and protective effect of biodiversity and green space.

Streets and Stress: A Pilot Study on How Quality and Design of Streets Impacts on Urban Stress.

OBJECTIVES: To identify how quality and design of streets impacts urban stress. BACKGROUND: Few studies have comprehensively addressed environmental factors affecting stress in urban public spaces. However, a remarkable portion of our everyday life is spent in public spaces, particularly streets. METHOD: This study seeks to evaluate the effect of three types of streets as major public spaces on stress. These include a street with the dominance of green spaces (A), a motorist-oriented street (B), and a pedestrian street (C). For this purpose, we selected a group of participants (n = 16) aged 20-30, with an equal number of men and women who were generally healthy and had normal stress levels. Participants were asked to wear an electroencephalogram (EEG) headset, walk different streets, and answer the Perceived Restorativeness Scale (PRS) and urban design qualities questionnaires. RESULTS: According to the results, participants experienced the highest stress in street type B and the lowest in type A. CONCLUSIONS: Green space and vegetation, a sense of security, privacy and coziness, climatic comfort, and safety of space had the most positive effect on stress reduction. Whereas noise pollution, vehicle traffic, and crowdedness were the most critical factors of stress. Finally, our findings suggest that the component of green space has a more significant effect on stress reduction compared with the elimination of vehicle traffic.

Shaping the healthy subject in gentrified spaces: Two case studies in Barcelona (Spain).

Several studies have analysed the impact of gentrification on health. However, a more in-depth examination of the constitutive role of health discourses in shaping spaces is required. This article explores the links between the gentrification process and the subjectification of healthy subjects through a critical discourse analysis of 35 walking interviews and a visual semiotic analysis of 140 shopfronts. Health is put forth as a super value to justify market interference in the configuration of urban space and class privilege based on the health products and healthy practices that have undergone a process of elitisation.

COVID-19, Cities and Inequality.

COVID-19 has changed our lives and will likely leave a lasting imprint on our cities. This paper reviews how the pandemic has altered the way people commute, work, collaborate, and consume, especially its reflection on urban space and spatial inequality. We conceptualize these urban changes as structural transformation, accelerated transition, and temporal change. First, we have seen more structural transformation far exceeding scholars' earlier predictions, especially remote working and global supply chain restructuring. Second, COVID-19 has accelerated the processes of digitalization and sustainable transition. While COVID-19 has contributed to suburbanization and urban sprawl, it has also raised the significance of green spaces and the environment. Third, COVID-19 reduced human impact on the environment, which might be temporary. Last, the pandemic has also amplified the pre-existing inequalities in urban areas, created a more fragmented and segregated urban landscape, and expanded the scope of urban inequality research by connecting health inequality with environmental and socio-injustice. We further discuss the emergence of post-pandemic urban theories and identify research questions for future research.

A momentary lack of rituals: urban festivities cancelations in Geneva, Turin, and Zurich during the COVID-19 lockdowns.

Rituals of territorial belonging as established practices of inclusion improve dynamics of belonging and coexistence. They are particularly significant in the city where people need rituals to trust each other. But what happens when rituals disappear? The Covid-19 pandemic is an experiment on a societal level on the role of rituals. We will analyze three canceled or strongly modified traditional events in Geneva, Zurich, and Turin. We conclude that these cancellations of rituals in urban public spaces generated a lack of territorial belonging and produced mistrust and anger, but at the same time pushed people to develop new dynamics to fill this void. Frustration over the cancellation was transformed into agency. This sense of emptiness was filled through the multiplication of personal and social rituals, through the rediscovery of the city's territory alone or with their groups of affiliation, and through new digital rituals linked to the urban ritual.

Women and cities. The conquest of urban space.

In the city of the Nineteenth-century, transformed by the values of the French revolution and by the modernity, women did not have yet full citizenship. The public space was still strongly a male space and women, still with a weak public subjectivity, remained the object of the male gaze. Women have begun a process of conquering urban space by claiming their right to the city, through their physical presence in the city itself. Through physical space, women have claimed their full symbolic citizenship. The project of an inclusive city takes shape from the public demands of women who, as Annie Hockshild wrote, gave birth to the most important revolution of the 20th century. However it is a stalled revolution that still today requires a legislative protection for the project of the substantial equality, which is still not fully achieved. In addition to the various national legislations, international legislation also recognizes the central objective of guaranteeing women's right to full citizenship. In the second part of the article, the focus is precisely on the normative content of this legislation and in particular on the objectives of the UN Agenda 2030.

Urban Therapy-Urban Health Path as an Innovative Urban Function to Strengthen the Psycho-Physical Condition of the Elderly.

The current approach to stimulating elderly physical activity mostly uses medical rehabilitation methods or popular forms of outdoor recreation. In the context of an ageing population, there is a growing demand for innovative rehabilitation methods that use information technology. In this article, we present the Urban Health Path as an innovative form of activation for older people using urban therapy, where the architectural elements, such as details, façade features, and urban furniture, inspire movement and attentiveness in the experience of space. The concept is supported by a mobile application that takes into account the specific preferences of older users. Our concept of the physical and cognitive activation of older people was the result of a user-centred design approach and it was tested as a prototype solution. At the same time, the aim of this article is to identify opportunities and limitations for the implementation of this type of solution in other urban spaces. The article presents the process of developing a solution using the Design Thinking method. The process was focused on the needs and preferences of older people. The results of the research project indicate the main important guidelines for implementing the Urban Health Path as a new form of urban facility in the city space.

How might we utilise the concept of botanic gardens' in urban contexts to challenge plant blindness?

Plant blindness remains an understudied Anthropocentric concept. There is a societal naivety to the importance of plants, and lack of awareness of the human impact of plant life, which renders many 'plant blind'. This research develops a Plant Blindness (PB) scale to address plant blindness within a botanic and urban space, pursuing an investigation into the motivations and beliefs of people in terms of plant awareness, plant fascination and conservationist efforts. Interviews with specialists within botany and horticulture suggest how we might better understand and utilise the function of botanic gardens' within an urban context, using botanic spaces to further amplify societal interest in plant life, thus challenging plant blindness. Botanic gardens' document collections of living plants, researching and setting exemplar sustainable and ethical standards for the conservation and cultivation of rare and threatened plants, educating and bringing global plant conservation to the forefront of our natural world. Botanic gardens research innovation, scientific knowledge, heritage and expertise in sustaining a globally diverse range of plant species could be advantageous in the future design of urban spaces. It is through establishing active engagement between botanic spaces and urban spaces that plant blindness can be challenged, establishing a future vision for botanic gardens and botanic spaces, exploring the role botany could adopt within society.

Inclusive urban space production model for sustainable development in South Africa.

The year 1994 marked the dawn of the new, democratic South Africa. It also brought its own sets of challenges to the country. One such challenge was urban space. Regrettably, the new dispensation inherited still very much race-based urban areas. The distinguishing feature of urban space in South Africa is the phenomenon of exclusion, which causes deformity, and disappearance of urban structure. Exclusion has become a permanent visual reality in cities in which walled and gated communities divide the urban tissue and take up a large part of the urban space. The aim of this paper is to present results of a study that sought to examine the factors that influence urban space production, and with particular focus on the roles of the state, private sector, and community. Participation by all of them is essential to enhance inclusive urban space production for sustainability. The study demonstrated a concurrent mixed method design (case study and survey questionnaire). Results from these two concurrent approaches were merged to yield the final model. Both sets of results indicated that the intention to promote inclusive developments is predicted by seventeen dependent variables categorically presented under urban development characteristics, exclusive development enablers, inclusive development barriers, and sustainability criteria. The results of this inquiry are significant because they bring together the interdisciplinary perspectives to discern comprehensively the idea of inclusivity and sustainability in urban space production. The responsive model developed as a key product of this study aims to assist policymakers, planners, designers, landscapers, and developers as a guideline for facilitating inclusive and sustainable urban development.

From culturalisation to individuation: the role of urban spaces in shaping intergroup contacts and symbolic boundary perceptions.

This article investigates ethnic boundary perceptions among people without a migration background living in majority-minority neighbourhoods in six western European cities. The main research question is whether people without migration background who have contact with migrant groups in their everyday life surroundings perceive ethnic boundaries as blurred (i.e. individuation) or as bright (i.e. culturalisation). The main argument of this article is that boundary perceptions are importantly shaped by the specific urban micro-setting in which people come into contact with migrant groups. Drawing on data from a large-scale survey conducted in Amsterdam, Antwerp, Hamburg, Rotterdam, Malmo and Vienna, the study examines how urban micro-setting affects ethnic boundary perceptions (i.e. individuation or culturalisation). The results show that contact with migrant groups in parochial spaces is significantly and strongly related to the blurring of group boundaries (i.e. individuation), while exposure in public spaces has no significant effect on boundary perceptions.

Research on Wind Environment and Morphological Effects of High-Rise Buildings in Macau: An Example from the New Reclamation Area around Areia Preta.

The Macau peninsula is close to the tropical ocean, with a high population density and a large number of high-rise buildings, which require a windy environment with good ventilation and heat dissipation. Based on residential samples and the degree of agglomeration, the high-rise residential area in Areia Preta was selected as the focus of this study. Meanwhile, summer typhoons pose serious safety risks to high-rise buildings. Therefore, it is necessary to study the connection between spatial form and the wind environment. First of all, this research is based on relevant concepts and the wind environment evaluation system of high-rise buildings and conducts research on high-rise residential areas in Areia Preta. PHOENICS software is used to simulate the prevailing monsoon in winter and summer, as well as a typhoon in an extreme wind environment, and summarize the wind environment's characteristics. Secondly, by comparing the parameter calculation and simulation results, the possible relationship between the causes of each wind field is studied. Finally, conclusions are drawn about the urban form and wind environment of the site, and corresponding control strategies are proposed to reduce the shielding effect between buildings and typhoon damage. It can be used as a theoretical basis and reference point for urban construction and high-rise building planning and layout.

Acoustic information masking effects of natural sounds on traffic noise based on psychological health in open urban spaces.

The use of existing resources, such as natural sounds, to promote the mental health of citizens is an area of research that is receiving increasing attention. This research contributes to existing knowledge by combining a field psychological walk method and an experimental acoustic control method to compare the acoustic information masking effects of water and birdsong sounds on traffic noise based on the psychological health responses of 30 participants to such effects. The influence of traffic noise and contextual sounds on the psychological health of participants identified the potential of natural sounds in the acoustic information masking of traffic noise. Furthermore, it was found that 65.0 dBA water sounds did not mask 60.0 dBA traffic noises. However, 45.0 dBA birdsong sounds did mask it, but this effect was not significant. Additionally, contextual factors with and without crowd activity sounds were not significant in influencing psychological health through birdsong. This study contributes to public health cost savings. It may also guide the development of new ideas and methods for configuring open urban spaces according to public health needs.

Measuring social resilience in cities: An exploratory spatio-temporal analysis of activity routines in urban spaces during Covid-19.

Covid-19 has dramatically changed life in cities across the globe. What remains uncertain is how national policies and appeals to comply with suggested rules translate to changes in the behaviour of citizens in urban areas. This lack of local knowledge leaves urban policy makers and planners with few clues as to the determinants of social resilience in cities during protracted crises like a pandemic. Methods are required to measure the capacity of people to conduct routine activities without risking exposure to a prevalent disease, particularly for those most vulnerable during a health crisis. By spanning the fields of urban resilience, human geography, mobility studies and the behavioural sciences, this study explores how to measure social resilience in cities during a protracted crisis. Using a public participation GIS online platform, we observe changes in citizen behaviour within urban spaces during the Covid-19 pandemic. Inhabitants from three districts of a Dutch city mapped their activity routines during the lockdown period and during the year before the pandemic. Spatio-temporal analysis reveals changes in the clustering of activities into what we describe as 'activity bubbles'. We reflect on the influence of the urban space on these changes and assess the contribution of this exploratory research methodology for gaining insights into behavioural change. Implications for urban planning and resilience theory are discussed.

The Problem of Monitoring the Psycho-Physical Condition of Seniors during Proposed Activities in Urban Space.

The world's population is rapidly ageing, which places a heavy burden on traditional healthcare systems with increased economic and social costs. Technology can assist in the implementation of strategies that enable active and independent ageing by promoting and motivating health-related behaviours, monitoring, and collecting data on daily life for assessment and for aiding in independent living. ICT (Information and Communication Technology) tools can help prevent cognitive and physical decline and social isolation, and enable elderly people to live independently. In this paper, we introduced a comprehensive tool for guiding seniors along the designed urban health paths employing urban architecture as an impulse to perform physical and cognitive exercises. The behaviour of seniors is monitored during their activities using wearable sensors and mobile application. We distinguished three types of data recipients (seniors, path/exercise designers, and the public), for whom we proposed methods of analysing the obtained data and examples of their use. In this work, a wide range of diverse information was examined from which short- and long-term patterns can be drawn. We have also shown that by fusing sensory data and data from mobile applications, we can give context to sensory data, thanks to which we can formulate more insightful assessments of seniors' behaviour.

Green space in health research: an overview of common indicators of greenness.

Human environments influence human health in both positive and negative ways. Green space is considered an environmental exposure that confers benefits to human health and has attracted a high level of interest from researchers, policy makers, and increasingly clinicians. Green space has been associated with a range of health benefits, such as improvements in physical, mental, and social wellbeing. There are different sources, metrics and indicators of green space used in research, all of which measure different aspects of the environment. It is important that readers of green space research understand the terminology used in this field, and what the green space indicators used in the studies represent in the real world. This paper provides an overview of the major definitions of green space and the indicators used to assess exposure for health practitioners, public health researchers, and health policy experts who may be interested in understanding this field more clearly, either in the provision of public health-promoting services or to undertake research.

Physical Activity Behavior, Motivation and Active Commuting: Relationships with the Use of Green Spaces in Italy.

Many benefits of physical activity (PA) are observed with weekly average volumes of 150-300 min at moderate intensity. Public parks may be an attraction for many people living in the city and could help to achieve the recommended dose of PA. The present study aims to understand the motivation that drives people to a park and evaluate the amount of PA practiced by park-goers. A questionnaire was anonymously administered to 383 voluntary visitors to the Arcoveggio park (Bologna), aged 18-70 years. Sixty-one percent of participants practiced outdoor PA. Differences in park use between sexes and age groups were found. PA was higher in men than in women and in the 18-30 age group than in other age groups. Most participants travelled to the park in an active way (86.4%), resulting in easier attainment of the recommended amount of PA (64.5%). The main motivations for using the park were related to relaxation, performing PA, or both. According to a multiple regression model, the time per week spent at the park, the method of getting there, and the kind of PA were significant explanatory variables of the amount of PA practiced. In particular, the highest number of minutes of PA was achieved by those who travelled to the park by running, while those using vehicles presented the lowest number. All initiatives to promote active commuting and activities in the urban park represent an important strategy to improve health, supporting adults to lead an active lifestyle.

Huerta urbana comunitaria, más que lechugas entre cemento. Producción social de territorios saludables / Community Urban Garden, More Than Lettuce among Cement. Social Production of Healthy Territories

Effect of a Park-Based Physical Activity Intervention on Psychological Wellbeing at the Time of COVID-19.

Practicing regular physical activity in green spaces has been invocated as a promising strategy for improving wellbeing in urban settings. The aim of the study was to assess the effect of a structured park-based physical activity intervention, the "Moving Parks" project, on citizens' wellbeing at the time of COVID-19. The intervention was carried out in six public parks in Bologna (Italy) and administered by qualified instructors (from May 2021 to September 2021). The Psychological General Well Being Index short form questionnaire was administered before and after the three months of outdoor activities. A total of 328 participants completed the questionnaire at the beginning and at the end of the project. In September 2021, all psychosocial domains of the questionnaire (anxiety, depressed mood, self-control, positive well-being, vitality energy, and vitality-tiredness) significantly improved in the female sample (p value < 0.01) and only the last two in the male sample (p value < 0.05). The "Moving Parks" project seems to be able to improve citizens' psychological wellbeing, particularly in women.

New trends in biotechnological applications of photosynthetic microorganisms.

As a source of several valuable products, photosynthetic microorganisms (microalgae and cyanobacteria) have many applications in biomedical, electrochemical, and urban-space fields. Microalgal and cyanobacterial (photoautotrophs) implementations have been the subject matter of several reviews, which mainly focused on exploring effective methods of their harvesting, optimal cultivation conditions, energy conversion efficiency, and new strategies for microalgal health-promoting compound recovery. This review highlights recent investigations into biomedical, urban, environmental, and electrical engineering microalgae and cyanobacteria applications over the last seven years. A brief historical outline of advances in photoautotroph-based technologies is presented prior to an exploration of the important role of these microorganisms in combating global warming and food and energy insecurity. Special attention is given to the photosynthetic oxygen production of algae and the possibility of treating hypoxia-associated diseases such as cancer or tissue injuries. Photoautotroph applications in microrobotics, drug delivery and wound healing systems, biosensors, and bioelectronics are also introduced and discussed. Finally, we present emerging fabrication techniques, such as additive manufacturing, that unleash the full potential of autotrophic, self-sufficient microorganisms at both the micro- and macroscales. This review constitutes an original contribution to photoautotroph biotechnology and is thought to be impactful in determining the future roles of microalgae and cyanobacteria in medical, electrical, or urban space applications.

Social implications of autonomous vehicles: a focus on time.

The urban environment is increasingly engaging with artificial intelligence, a focus on the automation of urban processes, whether it be singular artefacts or city-wide systems. The impact of such technological innovation on the social dynamics of the urban environment is an ever changing and multi-faceted field of research. In this paper, the space and time defined by the autonomous vehicle is used as a window to view the way in which a shift in urban transport dynamics can impact the temporal experience of an individual. Using the finite window of time created by an autonomous vehicle, a theoretical framework is put forward that seeks to show how contrasting narratives exist regarding the experience of the window of time within the autonomous vehicle. By taking a theoretical approach informed by social theory, the dissolution of barriers between separate spheres of life is explored to highlight the increased commodification of time. In focusing on both the space and time created by the autonomous vehicle this approach seeks to highlight how artificial intelligence can provide a contemporary space in the urban environment while also opening a new window of time. The cognitive dissonance observed when comparing the narratives of autonomous vehicle stakeholders and the historical shift in time use leads to a belief that technology makes the user more free in terms of time. With this paper the autonomous vehicle is shown to be an ideal space and time to view the way in which the use of such technology does not increase free-time, but further dissolves the boundaries between what is and what is not work-time.
