Many schools in Sweden lack a proper indoor environment due to, e.g., poor thermal-envelope properties, overcrowded classes, poor visual appearance and insufficient ventilation. This study aims to explore the integration of a large number of indoor green plants into classrooms’ environments. This case study consists of three parts: measurements of the indoor environment including a final energy model, a questionnaire to the pupils with questions about their well-being and qualitative interviews with teachers. The case was two classrooms in a secondary education facility in central Sweden with an average annual temperature of 3 °C and a long and dark winter period with snow. The results showed 10% lower CO₂ and slightly higher and more stable temperatures due to the green plants. Worries about climate change and war among the pupils decreased after several months with the plants and worry about infectious disease increased. The teachers experienced fresher air from the plants and used the plant stands for a flexible classroom design. The conclusion is that indoor plants have the potential to contribute to a better indoor environment, but due to the high number of uncontrolled variables (including the effect of COVID-19) in measurements of real-life conditions, more studies are needed.

The COVID-19 pandemic has limited people’s visitation to public places because of social distancing and shelter-in-place orders. According to Google’s community mobility reports, some countries showed a decrease in park visitation during the pandemic, while others showed an increase. Although government responses played a significant role in this variation, little is known about park visitation changes and the park attributes that are associated with these changes. Therefore, we aimed to examine the associations between park characteristics and percent changes in park visitation in Harris County, TX, for three time periods: before, during, and after the shelter-in-place order of Harris County. We utilized SafeGraph’s point-of-interest data to extract weekly park visitation counts for the Harris County area. This dataset included the size of each park and its weekly number of visits from 2 March to 31 May 2020. In addition, we measured park characteristics, including greenness density, using the normalized difference vegetation index; park type (mini, neighborhood, community, regional/metropolitan); presence of sidewalks and bikeways; sidewalk and bikeway quantity; and bikeway quality. Results showed that park visitation decreased after issuing the shelter-in-place order and increased after this order was lifted. Results from linear regression models indicated that the higher the greenness density of the park, the smaller the decrease in park visitation during the shelter-in-place period compared to before the shelter-in-place order. This relationship also appeared after the shelter-in-place order. The presence of more sidewalks was related to less visitation increase after the shelter-in-place order. These findings can guide planners and designers to implement parks that promote public visitation during pandemics and potentially benefit people’s physical and mental health. Full article

Urban ecosystem services have become a main issue in contemporary urban sustainable development, whose efforts are challenged by the phenomena of world urbanization and climate change. This article presents a study about the ecosystem services of green infrastructure towards better respiratory health in a socioeconomic scenario typical of the Global South countries. The study involved a data science approach comprising basic and multivariate statistical analysis, as well as data mining, for the municipalities of the state of Paraná, in Brazil’s South region. It is a cross-sectional study in which multiple data sets are combined and analyzed to uncover relationships or patterns. Data were extracted from national public domain databases. We found that, on average, the municipalities with more area of biodiversity per inhabitant have lower rates of hospitalizations resulting from respiratory diseases (CID-10 X). The biodiversity index correlates inversely with the rates of hospitalizations. The data analysis also demonstrated the importance of socioeconomic issues in the environmental-respiratory health phenomena. The data mining analysis revealed interesting associative rules consistent with the learning from the basic statistics and multivariate analysis. Our findings suggest that green infrastructure provides ecosystem services towards better respiratory health, but these are entwined with socioeconomics issues. These results can support public policies towards environmental and health sustainable management. Full article

Since indoor, sedentary lifestyles became prevalent in society, humans have lost a sustainable connection to nature. An intervention utilizing outdoor horticultural activities could address such a challenge, but their beneficial effects on the brain and emotions have not been characterized in a quantitative approach. We aimed to investigate brain activity and emotional changes in adults in their 20s during horticultural activity to confirm feasibility of horticultural activity to improve cognitive and emotional states. Sixty university students participated in 11 outdoor horticultural activities at 2-min intervals. We measured brain waves of participants’ prefrontal cortex using a wireless electroencephalography device while performing horticultural activities. Between activities, we evaluated emotional states of participants using questionnaires. Results showed that each horticultural activity showed promotion of brain activity and emotional changes at varying degrees. The participants during physically intensive horticultural activities—digging, raking, and pruning—showed the highest attention level. For emotional states, the participants showed the highest fatigue, tension, and vigor during digging and raking. Plant-based activities—harvesting and transplanting plants—made participants feel natural and relaxed the most. Therefore, this pilot study confirmed the possibility of horticultural activity as a short-term physical intervention to improve attention levels and emotional stability in adults. Full article

Growing evidence suggests that connection to nature may be linked to mental health and well-being. Behavioral changes brought about by the COVID-19 pandemic could negatively affect adolescents’ connection to nature, subsequently impacting health and well-being. We explored the relationship between connection to nature and well-being before and during the pandemic through a nationally representative survey of adolescents across the United States (n = 624) between April and June 2020. Survey items focused on connection to nature, mental well-being, and participation in outdoor activities before and during the pandemic. Paired-sample t-tests revealed declines in connection to nature, mental well-being, and participation in outdoor activities during the pandemic. Multiple linear regression analyses examining connection to nature’s mediating role between outdoor activity participation and mental well-being indicated that connection to nature fueled higher levels of mental well-being at both time intervals. Z scores comparing connection to nature’s mediating role between outdoor activity participation and mental well-being between time intervals indicate that during the pandemic, the direct effect of outdoor activities on mental well-being increased, generating a greater impact than before the pandemic. This study illustrates how the health and well-being benefits associated with adolescents’ outdoor activities are reinforced when those activities also foster a stronger connection to nature.

Forest is a natural resource that provides natural walking as a popular leisure activity for urban residents. From the perspective of “dose of nature”, continuous contact with natural environments and engagement in natural activities can gradually promote positive health benefits. This study aims to explore the “cumulative frequency of nature dose” through regular forest walking. Ten college students were recruited to walk once a week for 30 min in the campus forest. Eight weeks of forest walking experiences were collected by administering questionnaires on nature relatedness, mental health, restorativeness, and learning engagement before the first walk, as well as after the fourth and the eighth walks. The findings of this study revealed that regular forest activities can induce accumulated natural benefits. By taking at least 30 min of forest walks once a week continuously for eight weeks, the subjects improved their mental health, increased learning engagement in school, gained more attention recovery and reflection experiences, and re-established a relationship with nature. In addition, different doses of natural benefits were observed for different cumulative processes. Full article

The variability of nature and the nature construct have complicated interpretations of empirical evidence from nature-based health studies. The challenge of defining nature exposure for purposes of methodological standardization may encompass constructs beyond vegetated landcover. This study offers a new construct for defining ‘nature exposure’ that considers cultural sets and nature familiarity. Focus group discussions across the United States (N = 126) explored the concept of what constitutes the relationship to nature. The participant diversity included regions, cultural demographics, cumulative nature experience, and everyday nature exposure. Mixed methods of semi-structured discussion and a photo exercise that prompted nature connectedness allowed for data triangulation and the detection of contradictions between approaches. Individuals conceptualized nature in ways reflecting highly personal and differentiated experiences, which defied consensus toward a single nature construct. The group scoring of photo imagery showed consistent high and low levels of nature connectedness with respect to wildness and outdoor urban venues, respectively, but diverged in the assessment of nature within the built environment. Everyday nature exposure significantly differentiated how groups conceptualized and related to nature imagery. This result may indicate an unmet biophilic need among groups with low backgrounds of nature exposure. The contrasts between the discussion content and the observed reactions to nature imagery showed the value of using mixed methods in qualitative research. Full article

We investigated the effects of pedestrian environments on parents’ walking behavior, their perception of pedestrian safety, and their willingness to let their children walk to school. This study was a simulated walking environment experiment that created six different pedestrian conditions using sidewalks, landscape buffers, and street trees. We used within subjects design where participants were exposed to all six simulated conditions. Participants were 26 parents with elementary school children. Sidewalks, buffer strips, and street trees affected parents’ decisions to: walk themselves; let their children walk to school; evaluate their perception whether the simulated environment was safe for walking. We found that the design of pedestrian environments does affect people’s perceptions of pedestrian safety and their willingness to walk. The presence of a sidewalk, buffer strip, and street trees affected parents’ decision to walk, their willingness to let their children walk to school and perceived the pedestrian environment as safer for walking. The effects of trees on parents’ walking and perception of pedestrian safety are greater when there is a wide buffer rather than a narrow buffer. It was found that parents are more cautious about their children’s walking environments and safety than their own. Full article
