The Shock of a Social Disaster in an Age of (Nonsocial) Risk
The distinctly socially differentiated impact of the New Orleans flood stands in marked contrast to the nonsocial character of disasters and inquiries we have become accustomed to in the “risk society.
Forests are chill: The interplay between thermal comfort and mental wellbeing
As global warming and urbanisation intensify unabated, a growing share of the human population is exposed to dangerous heat levels. Trees and forests can effectively mitigate such heat alongside numerous health co-benefits like improved mental wellbeing. Yet, which forest types are objectively and subjectively coolest to humans, and how thermal and mental wellbeing interact, remain understudied. We surveyed 223 participants in peri-urban forests with varying biodiversity levels in Austria, Belgium and Germany. Using microclimate sensors, questionnaires and saliva cortisol measures, we monitored intra-individual changes in thermal and mental states from non-forest baseline to forest conditions. Forests reduced daytime modified Physiologically Equivalent Temperature (mPET; an indicator for perceived temperature) by an average of 9.2 °C. High diversity forests were the coolest, likely due to their higher stand density. Forests also lowered thermal sensation votes, with only 1 % of participants feeling ‘warm’ or ‘hot’ compared to 34 % under baseline conditions. Despite the desire for a temperature increase among 47 % participants under cool forest conditions, approximately two-thirds still reported feeling very comfortable, in contrast to only one-third under baseline conditions. Even at a constant perceived temperature, participants were 2.7 times more likely to feel warmer under baseline conditions compared to forests. A forest-induced psychological effect may underlie these discrepancies, as supported by significant improvements in positive and negative affect (emotional state), state anxiety and perceived stress observed in forests. Additionally, thermal and mental wellbeing were significantly correlated, indicating that forest environments might foster a synergy in wellbeing benefits
The more the merrier? Perceived forest biodiversity promotes short‐term mental health and well‐being—A multicentre study
1. Forests can foster mental health and well-being. Yet, the contribution of forest biodiversity remains unclear, and experimental research is needed to unravel pathways of biodiversity–health linkages. Here, we assess the role of tree species richness, both actual and perceived, and how stress reduction and attention restoration can serve as potential mediating pathways to achieve positive mental health and well-being outcomes. 2. We conducted an experimental, multicentric field study in three peri-urban forests in Europe, employing a mixed design with 223 participants, that comprised 20-min stays in forests with either low, medium or high tree species richness or a built control. Participants' short-term mental health and well-being and saliva cortisol as a biomarker of stress were measured before and after the intervention. 3. Forest visits for 20 min were found to be beneficial for participants' short-term mental health, short-term mental well-being, subjective stress, subjective directed attention and perceived restorativeness compared with a built environment. No differences were found for the physiological stress indicator saliva cortisol, which decreased in both the forest and the built environments. 4. Increased perceived biodiversity—possibly linked to structural forest attributes— was significantly associated with well-being outcomes, while no association was found for differences in actual tree species richness. Structural equation modelling indicates that higher levels of perceived biodiversity had an indirect effect on short-term mental health and well-being through enhancing perceived restorativeness. 5. While we found no evidence of actual tree species richness effects, perceived biodiversity was associated with positive short-term mental health and well-being outcomes. Understanding these biodiversity–health linkages can inform conservation management and help develop effective nature-based interventions for promoting public health through nature visits
Nature-based social prescribing programmes: opportunities, challenges, and facilitators for implementation.
Background
Evidence on the health benefits of spending time in nature has highlighted the importance of provision of blue and green spaces where people live. The potential for health benefits offered by nature exposure, however, extends beyond health promotion to health treatment. Social prescribing links people with health or social care needs to community-based, non-clinical health and social care interventions to improve health and wellbeing. Nature-based social prescribing (NBSP) is a variant that uses the health-promoting benefits of activities carried out in natural environments, such as gardening and walking. Much current NBSP practice has been developed in the UK, and there is increasing global interest in its implementation. This requires interventions to be adapted for different contexts, considering the needs of populations and the structure of healthcare systems.
Methods
This paper presents results from an expert group participatory workshop involving 29 practitioners, researchers, and policymakers from the UK and Germany’s health and environmental sectors. Using the UK and Germany, two countries with different healthcare systems and in different developmental stages of NBSP practice, as case studies, we analysed opportunities, challenges, and facilitators for the development and implementation of NBSP.
Results
We identified five overarching themes for developing, implementing, and evaluating NBSPCapacity Building; Accessibility and Acceptability; Networks and Collaborations; Standardised Implementation and Evaluation; and Sustainability. We also discuss key strengths, weaknesses, opportunities, and threats for each overarching theme to understand how they could be developed to support NBSP implementation.
Conclusions
NBSP could offer significant public health benefits using available blue and green spaces. We offer guidance on how NBSP implementation, from wider policy support to the design and evaluation of individual programmes, could be adapted to different contexts. This research could help inform the development and evaluation of NBSP programmes to support planetary health from local and global scales
