The impact of gardening on mental resilience in times of stress: A case study during the COVID-19 pandemic in Singapore

Changing Perceptions of Ornamental Plants in Urban Yangon, Myanmar

Gardening is a popular pastime for people from all walks of life in Yangon, the most populous city of Myanmar and its former capital. The cultivation of ornamental plants has continued uninterrupted despite decades of social and political crises that have plagued the country, but there are indications that people's tastes have changed considerably. These changing tastes are documented here through interviews of nursery owners and amateur gardeners from Yangon. This study also investigates the development of naming patterns in Burmese, in particular the names coined for recently introduced plants. A total of 176 older and 156 newer (introduced over the last two decades) ornamental plants grown in Yangon were documented; of the former category, 75% were still available in nurseries, whereas the rest were no longer popular. The newer plants had significantly fewer unanalysable names than the older plants, suggesting a modern preference for descriptive/allusive labels. This also applies to native, wild-harvested orchid species. Many of the newer, introduced orchid hybrids have not been given Burmese names, but are only referred to by shorthand labels like dendro and vanda. This study provides a first, linguistically informed ethnobiological report of ornamental plants in Myanmar.

Comparative analysis of visual-thermal perceptions and emotional responses in outdoor open spaces: Impacts of look-up vs. look-forward viewing perspectives

Horizontal and vertical viewing perspectives exert varying influences on the environmental perceptions and emotional states of college students. Despite this, scant research addresses the impact on this demographic. We selected typical campus open spaces for comprehensive physical parameter assessments, encompassing meteorological and spatial characteristics. A cohort of 36 healthy college students participated in a questionnaire survey designed to ascertain shifts in visual comfort, thermal comfort, and emotional responses when viewing landscapes in look-forward and look-up orientations. Key findings following both viewing modalities included: 1) a notable rise in mean visual comfort vote (MVCV), by 1.22 for look-forward and 1.01 for look-up, with a pronouncedly higher sunlight sensation vote (SSV) for the latter orientation; 2) a significant increase in thermal comfort vote (TCV), although the difference in increments between the two viewing angles was minimal; 3) Positive affect (PA) exhibited considerable improvement in both viewing conditions, while negative affect (NA) was markedly reduced in the look-up condition relative to look-forward viewing; 4) The SSV was predominantly influenced by the trunk ratio and canopy-to-trunk ratio, with substantial weights of 31.47% and 32.15%, respectively. Landscape element diversity emerged as the most critical factor affecting visual comfort vote (VCV) and aesthetic assessment score (AAS), with overwhelming weights of 70.67% and 63.15%, respectively. Moreover, the leaf ratio was identified as the chief determinant of emotional responses. Our results provide insights into the design of campus spaces for enhanced student well-being.

Nature exposure and mental health during the COVID-19 pandemic: A Navigation Guide systematic review with meta-analysis

Prior reviews have highlighted that nature exposure was a valuable coping strategy enhancing mental health during the COVID-19 pandemic. However, no existing reviews have determined the quality of evidence and risk of bias of the empirical studies supporting this claim. To address this gap, we employed a Navigation Guide systematic review and meta-analysis approach to investigate associations between nature exposure and mental health during the pandemic. Searches in PubMed, Web of Science, Scopus, CINAHL, and PsycInfo retrieved relevant articles published between January 1, 2020, and March 4, 2024. We used the Navigation Guide methodology to assess the risk of bias and Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) assessments to evaluate the overall quality of evidence. Our search retrieved 113 studies that met the inclusion criteria and reported diverse types of exposure, including nature availability, nature visit frequency, green space accessibility, and green space type, alongside associations with 12 mental health outcomes. Meta-analyses found access to gardens was associated with lower odds of depression [(Pooled odds ratio [OR] = 0.71, 95%CI = 0.61, 0.82), I2 = 0%, n = 3] and anxiety [(Pooled OR = 0.73, 95%CI = 0.63, 0.84), I2 = 0%, n = 3]. Increased time in green spaces was associated with lower level of stress [(Pooled Corr = -0.11, 95%CI = -0.17, -0.05), I2 = 0%, n = 2]. Higher frequency of visits to nature was associated with improved mental well-being [(Pooled standardized beta = 0.10, 95%CI = 0.07, 0.14), I2 = 0%, n = 2] and general mental health [(Pooled standardized beta = 0.11, 95%CI = 0.03-0.38), I2 = 82%, n = 2]. However, the number of pooled studies was small and the overall quality of evidence was "very low" for all outcomes, and high levels of bias were observed (26% of studies had high, 71% probably high). Nonetheless, given the trends in the results, nature-based solutions emphasizing exposure to gardens and green spaces near the home may have promoted psychological resilience during this public health crisis.

Which horticultural activities are more effective for children's recovery from stress and mental fatigue? A quasi-experimental study

Introduction

Studies have established the benefits of horticultural therapy and activities for human health and well-being. Nonetheless, limited research has been conducted on the potential restorative advantages and distinctions between different types of horticultural activities in terms of stress reduction.

Methods

This study employed a quantitative research method to investigate the stress recovery benefits of five horticultural activities (flower arrangement, sowing and transplanting seeds, kokedama crafting, pressed flower card making, and decorative bottle painting with dried flowers) and one reference activity (short composition writing) for children. The experiment was conducted in a children's activity center's multi-purpose classroom with 48 elementary students aged 9-12 years. The subjects first took a stress test to induce stress and then engaged in horticultural activities for 20 min. Physiological stress was assessed using electrocardiograms and electroencephalograms as feedback indicators. Psychological and emotional changes were determined using the Positive and Negative Affect Schedule for Children and Self-Assessment Manikin scales.

Results

The results demonstrated that horticultural activities greatly reduced physiological fatigue, and their recovery benefits were significantly greater than those of the reference activity. The recovery effects from different horticultural activities were similar across physiological indicators, although flower arrangement and sowing and transplanting seeds exhibited relatively robust recovery benefits. The heart rate and α-EEG-based generalized estimating equation revealed that horticultural activities offered significantly better relative recovery at each time phase of operation than the reference activity, with girls showing a 3.68% higher relative recovery value than boys. Flower arrangement and kokedama crafting offered better physiological recovery for students with prior horticultural experience, and these two activities received the highest scores in terms of positive effects and the "pleasure" dimension. Students believed that participating in horticultural activities resulted in a noteworthy increase in personal confidence and a greater sense of achievement.

Conclusion

The study suggests that horticultural activities that involve real and vibrant plants or natural materials and are more attractive have more stress-relieving benefits. We conclude that horticultural activities are beneficial leisure activities that aid in stress relief for children and that it is important to consider the attributes of activities when developing horticultural programs for elementary students.

The effectiveness of nature-based therapy for community psychological distress and well-being during COVID-19: a multi-site trial

During the COVID-19 pandemic, the world population faced various mental health challenges, highlighting a need for new community-based psychosocial interventions. This study aimed to investigate the effectiveness and feasibility of Nature-Based Therapy (NBT) for the community experiencing psychological distress during the pandemic. A multi-site trial comparing NBT and control groups was conducted in Korea with 291 participants exhibiting mild to severe depression or anxiety. A total of 192 participated in 30 sessions of therapeutic gardening, while 99 remained in the control group. Psychological distress and well-being were assessed using seven measures of depression, anxiety, daily activity, life satisfaction, mindfulness, stress, and loneliness. The effect sizes (Cohen's d) of NBT compared to the control group were medium to large: depression (0.583), anxiety (0.728), daily activity (1.002), life satisfaction (0.786), mindfulness (0.645), stress (0.903), and loneliness (0.695). Multilevel analysis revealed significant Time × Group interaction effects for all measures. Pearson correlation (r = - 0.28 to 0.71) showed that changes in all variables correlated significantly with each other, with small to large effect sizes. Therapeutic alliance at post-test positively moderated the intervention effects on the outcomes. We concluded that NBT is a promising psychosocial intervention for treating psychological distress for community dwellers.

Singapore COVID-19 data cross-validation by the Gaidai reliability method

Novel coronavirus infection (COVID-19) has exserted certain burden on global public health, spreading around the world with reportedly low mortality and morbidity. This study advocates novel bio and health system reliability approach, especially suitable for multi-regional environmental and health systems. Advocated spatiotemporal method has been cross-validated, versus well established bivariate Weibull method, based on available raw clinical dataset. The purpose of this study was to assess risks of excessive coronavirus death rates, that may occur within any given time horizon, and in any region or district of interest. This study aims at benchmarking of the novel Gaidai bio-reliability method, allowing accurate assessment of national public health system risks, for the years to come. Novel bio-system reliability approach is particularly suitable for multi-regional environmental and health systems, monitored for a sufficiently representative period of time. In case when underlying bio-system is stationary, or the underlying trend is known, long-term future death rate risk assessment can be done, and confidence intervals can be generated. Advocated methodology may to be useful for a wide variety of public health applications, thus, it is not limited to the example, considered here.

The effects of COVID-19 on Central Florida's community gardens: lessons for promoting food security and overall community wellbeing

For quite some time, food systems scholars, public health workers, and food justice activists have recognized structural problems in the global food system that can cause food insecurity and inequitable access to nutritious foods. The COVID-19 pandemic and the accompanying disruption in food supply chains (FSCs) exposed these problems and raised questions about how community gardening and urban agriculture might offer some solutions. In this article, we examine the effects of the pandemic on the operations of community gardens in Central Florida and the attempts of these gardens to address the disruption in food supplies in their local communities. We do so by using data drawn from two research strategies employed by the members of University of South Florida's Urban Food Sovereignty Group: (1) a survey conducted in 2021 of 45 leaders of community gardens throughout the Central Florida region; and (2) participation in the meetings and activities of a coalition of community gardens based in Tampa, Florida, from 2019 to 2022. Results reveal that although most community gardens in Central Florida were forced to change their routines in various ways (e.g., limiting the number of workers or volunteers who could work at the garden at the same time, or delivering workshops and education programs online instead of in-person), some gardens were able to maintain their regular operations and even reported increases in their membership or participation during the pandemic. Many community garden leaders also recognized the positive effect that community gardening seemed to have on their gardeners' mental health, noting that their gardens became places of refuge for gardeners who sought safe, outdoor spaces, to relieve stress and interact with their neighbors. These same leaders also observed the effect of the pandemic on residents' access to quality food, and intensified their efforts to provide more fresh food to pantries and traditional emergency food outlets. Survey respondents also shared important lessons they learned from the pandemic by suggesting that community gardens establish clear emergency protocols, use existing resources more efficiently, continue their educational programs, and strengthen their communications and cooperation with other gardens and actors in local food supply chains in order to ensure food security. We conclude by suggesting that one of the best ways that local communities can avert future food crises and strengthen their resilience is to root themselves more firmly in the principles of food sovereignty so they can sustain themselves when commercial FSCs are disrupted.

Natural environments, psychosocial health, and health behaviors in a crisis - A scoping review of the literature in the COVID-19 context

The COVID-19 outbreak led to major restrictions globally, affecting people's psychosocial health and their health behaviors. Thus, the purpose of this scoping review was to summarize the available research regarding nature and health in the COVID-19 context. Keywords relating to natural environments and COVID-19 were combined to conduct a systematic online search in six major databases. Eligibility criteria were a) published since 2020 with data collected in the COVID-19 context b) peer-reviewed, c) original empirical data collected on human participants, d) investigated the association between natural environments and psychosocial health or health behaviors, and e) English, German, or Scandinavian languages. Out of 9126 articles being screened, we identified 188 relevant articles, representing 187 distinct studies. Most research focused on adults in the general population and was predominantly conducted in the USA, Europe, and China. Overall, the findings indicate that nature may mitigate the impact of COVID-19 on psychological health and physical activity. Through a systematic thematic analysis of the extracted data, three primary themes were identified: 1) type of nature assessed, 2) psychosocial health and health behaviors investigated, and 3) heterogeneity in the nature-health relationship. Research gaps in the COVID-19 context were identified regarding I) nature characteristics that promote psychosocial health and health behaviors, II) investigations of digital and virtual nature, III) psychological constructs relating to mental health promotion, IV) health-promoting behaviors other than physical activity, V) underlying mechanisms regarding heterogeneity in the nature-health relationship based on human, nature, and geographic characteristics, and VI) research focusing on vulnerable groups. Overall, natural environments demonstrate considerable potential in buffering the impact of stressful events on a population level on mental health. However, future research is warranted to fill the mentioned research gaps and to examine the long-term effects of nature exposure during COVID-19.

Contribution of Home Gardens to Sustainable Development: Perspectives from A Supported Opinion Essay

Home gardening has a long history that started when humans became sedentary, being traditionally considered an accessible source of food and medicinal plants to treat common illnesses. With trends towards urbanization and industrialization, particularly in the post-World War II period, the importance of home gardens as important spaces for growing food and medicinal plants reduced and they began to be increasingly seen as decorative and leisure spaces. However, the growing awareness of the negative impacts of agricultural intensification and urbanization for human health, food quality, ecosystem resilience, and biodiversity conservation motivated the emergence of new approaches concerning home gardens. Societies began to question the potential of nearby green infrastructures to human wellbeing, food provisioning, and the conservation of traditional varieties, as well as providers of important services, such as ecological corridors for wild species and carbon sinks. In this context. and to foster adaptive and resilient social-ecological systems, our supported viewpoint intends to be more than an exhaustive set of perceptions, but a reflection of ideas about the important contribution of home gardens to sustainable development. We envision these humble spaces strengthening social and ecological components, by providing a set of diversified and intermingled goods and services for an increasingly urban population.

Nature's contributions in coping with a pandemic in the 21st century: A narrative review of evidence during COVID-19

While COVID-19 lockdowns have slowed coronavirus transmission, such structural measures also have unintended consequences on mental and physical health. Growing evidence shows that exposure to the natural environment (e.g., blue-green spaces) can improve human health and wellbeing. In this narrative review, we synthesized the evidence about nature's contributions to health and wellbeing during the first two years of the COVID-19 pandemic. We found that during the pandemic, people experienced multiple types of nature, including both outdoors and indoors. Frequency of visits to outdoor natural areas (i.e., public parks) depended on lockdown severity and socio-cultural contexts. Other forms of nature exposure, such as spending time in private gardens and viewing outdoor greenery from windows, may have increased. The majority of the evidence suggests nature exposure during COVID-19 pandemic was associated with less depression, anxiety, stress, and more happiness and life satisfaction. Additionally, nature exposure was correlated with less physical inactivity and fewer sleep disturbances. Evidence was mixed regarding associations between nature exposure and COVID-related health outcomes, while nature visits might be associated with greater rates of COVID-19 transmission and mortality when proper social distancing measures were not maintained. Findings on whether nature exposure during lockdowns helped ameliorate health inequities by impacting the health of lower-socioeconomic populations more than their higher-socioeconomic counterparts for example were mixed. Based on these findings, we argue that nature exposure may have buffered the negative mental and behavioral impacts of lockdowns during the COVID-19 pandemic. Recovery and resilience during the current crises and future public health crises might be improved with nature-based infrastructure, interventions, designs, and governance.

Physically apart but socially connected: Lessons in social resilience from community gardening during the COVID-19 pandemic

Urban green spaces, like community gardens, received increased attention during the COVID-19 pandemic. Drawing from an ethnographic study on participating in community garden activities in Edmonton, Canada and inputs from 194 gardeners and 21 garden coordinators, this paper captures the experiences of creating community during a pandemic. Garden coordinators had to rethink and rework their operating styles in keeping participants physically apart but socially connected. Participants confirmed that garden activities provided respite from the pandemic restrictions. Findings also indicate that some participants missed group activities like work bees and potlucks while others were able to re-create community in digital spaces and in chanced and informal interactions. This study draws from and subsequently contributes to the existing literature on social resilience provided by community gardens during and after a crisis event. It also provides policy recommendations on how the city administration can help facilitate garden activities during times of disruptions.

The Multi-Sites Trial on the Effects of Therapeutic Gardening on Mental Health and Well-Being

Although many people affected by COVID-19 suffer from some form of psychological distress, access to proper treatment or psychosocial interventions has been limited. This study aimed to examine the feasibility and preliminary effects of a therapeutic gardening program conducted during the COVID-19 pandemic. The program consisted of 30 sessions and was conducted at 10 nationwide sites in Korea from June to November 2021. Mental health and well-being were assessed using the Mental Health Screening Tool for Depressive Disorders, Mental Health Screening Tool for Anxiety Disorders, Engagement in Daily Activity Scale, brief version of World Health Organization Quality of Life, and Mindful Attention Awareness Scale. Cohen’s d value was calculated for the effect size, and a multilevel analysis was used to determine the longitudinal effects of therapeutic gardening. The effect sizes for depression, anxiety, daily activities, quality of life, and mindfulness were 0.84, 0.72, 0.61, 0.64, and 0.40, respectively. Multilevel analyses showed that all five mental health variables improved significantly over time as the therapeutic gardening program progressed. Therapeutic gardening is promising and applicable as a nature-based intervention to improve the mental health of individuals experiencing psychological distress especially in the COVID-19 pandemic.

“Connecting With Good People and Good Plants”: Community Gardener Experiences in New York State During the COVID-19 Pandemic

Community gardens are collective projects in which participants collaborate to maintain a garden. They provide many biophysical and cultural ecosystem services, contributing to individual and community resilience and wellbeing. These benefits may be even more appreciated during a crisis such as the COVID-19 pandemic. However, since community gardens require efforts from multiple gardeners in shared spaces, the pandemic also exposed some of their vulnerabilities. This study focuses on the benefits community gardens have offered during the COVID-19 pandemic, the challenges the pandemic posed to sustaining community garden activity, and recommendations to address these issues moving forward. We conducted our study in four cities in New York representing a gradient of socioeconomic and biophysical characteristics: Binghamton, Buffalo, Ithaca, and New York City. We collected data from surveys and semi-structured interviews with community gardeners and analyzed them using mixed models and thematic coding. The primary benefits gardeners derived from their community garden experiences were: a sense of connection with other gardeners, their communities, and nature; mental and physical wellbeing; and a safe space of refuge. In addition to material shortages (e.g., seeds), the biggest challenge gardeners faced due to the pandemic was the limited degree of socializing in the gardens resulting from personal behavioral changes and rules imposed by gardens. Despite the challenges, gardeners reported enjoying the 2020 garden season. The pandemic also created opportunities for gardens to serve their communities, such as organizing programs for composting, food donation and distribution, and home gardening. Our findings suggest that community gardens can be resilient sites of reprieve during crises such as the COVID-19 pandemic, providing essential benefits for gardeners and local residents. To sustain community garden resilience, we recommend community gardens and gardeners cultivate connections and diversity, within and between the biological and human communities of their gardens.

Green Space Visits and Barriers to Visiting during the COVID-19 Pandemic: A Three-Wave Nationally Representative Cross-Sectional Study of UK Adults

Green spaces have been found to promote physical activity, social contact, and mental wellbeing, however, there are inequalities in the use and experience of green spaces. The United Kingdom’s (UK) response to the COVID-19 pandemic imposed very substantial changes on its citizens’ lives which could plausibly affect their willingness to visit green spaces. These sudden lifestyle changes severely affected the population’s mental health, leading to a greater dependency on the positive influence of nature in reducing stress and improving mood. Whilst early cross-sectional evidence suggested an increased orientation to nature and visits to green spaces as a response to COVID-19 ‘lockdowns’, there is little longitudinal evidence about how sustained and equal these changes may have been. This study explored green space visits, barriers to visiting, and the inequalities of both of those over an entire year of the pandemic in the UK. Three waves of nationally representative cross-sectional surveys were administered by YouGov in April 2020, November 2020, and April 2021 (N = 6713). Data included reported visits to green spaces and, for those with no or infrequent visiting, perceived barriers including those plausibly related to the risk of COVID-19. Green space visits increased over the year as lockdown restrictions were relaxed; 68% of respondents reported green space visits in April 2021, compared with 49% in April 2020. However, the socio-economic inequalities in use were sustained and increased. COVID-19 related barriers fell over time, but there were indications of increased interest in green spaces among younger people. Further action is required to ensure that the positive impacts of green spaces are experienced equally, and that good quality green space is accessible to all.
