Semantic assessments of experienced biodiversity from photographs and on-site observations - a comparison

Since the 1960’s, public assessments of landscapes have often been carried out using photographic representations. How reliable and valid are these assessments compared with on-site observations? In the present study, participants have been asked to judge different areas in terms of a limited feature: the biodiversity of the area. Digitalized photos from six different study areas were made available on the Internet, along with a questionnaire consisting of a semantic form with specific words/expressions to be rated in relation to the photos (four per area). Participants were recruited via mailing lists and informal contacts. These results were compared with a study in which students and ecologists had rated the same places using the same form, but this time on-site. The Internet participants were also asked to state their profession/education to make comparisons possible. The comparisons revealed differences between on-site and photo-based ratings, but the main difference was expressed by on-site biologists regarding areas with the highest experienced biodiversity values, possibly due to their higher degree of expertise and use of more senses than can be used when judging photographs. Concerning laymen in particular, it is concluded that the comparison between on-site and photo-based ratings is not conclusive enough to allow us to determine whether it is appropriate to use one method as a substitute for the other

The Effect of Nature-Based Therapy May be Dose-Related: A Prospective Cohort Study of Nature-Based Therapy of Long-Term Patients Suffering from Stress-Related Mental Illness

Stress-related mental illness is increasing worldwide and leads to longterm illness. Approximately one billion people globally suffer from some mental disorder, and the increase in the number of people suffering from mental illness is swift. Most affected are women between the ages of 30 and 50, and the need for rehabilitation and return to work for these patients is great. Research indicates that being in nature can lead to stress recovery. The question is whether nature-based therapy can rehabilitate people suffering from long-term stress-related mental illness, and how much time is necessary for recovery in order to return to work

Does More Time in a Therapeutic Garden Lead to a Faster Return to Work? A Prospective Cohort Study of Nature-Based Therapy, Exploring the Relationship between Dose and Response in the Rehabilitation of Long-Term Patients Suffering from Stress

Background: Stress-related mental illness is increasing worldwide and leading to long-term illness. Most of those affected are aged 30-50, so the need for rehabilitation and return to work for these patients is great. Research indicates that staying in nature can lead to stress recovery. The question is whether nature-based therapy can rehabilitate people who suffer from long-term stress-related mental illness, and how long a period of rehabilitation is necessary. Methods and findings: The research was carried out at Alnarp Rehabilitation Garden, which is a specially designed health garden on the Swedish University of Agricultural Sciences’ campus area, where the participants in the study were treated by a licensed rehabilitation team. The intention was to examine three cohorts of participants prospectively. These were offered different lengths of a nature-based rehabilitation program through a natural experiment. Participants were referred to Alnarp Rehabilitation Garden from three local social insurance agencies that granted different lengths of rehabilitation programs: 8 weeks, 12 weeks and 24 weeks. The length of the program was determined by which local social insurance agencies they belonged to, not the participants' level of illness. Primary outcome was return to work. Other outcomes were occupational function, personal control and sense of coherence. The results showed that all three rehabilitation interventions gave significantly good results, but that longer nature-based rehabilitation led to significantly better results for all outcomes. The 12-week program provided 75% greater return to paid work and the 24-week program 120% greater return to paid work than the 8-week program. Conclusion: There is a significant positive relationship between treatment time in the rehabilitation garden and return to work. The study also indicates that the effects may level off after twelve weeks. More studies are needed to further investigate the relationships

COMSI®—A Form of Treatment That Offers an Opportunity to Play, Communicate and Become Socially Engaged through the Lens of Nature—A Single Case Study about an 8-Year-Old Boy with Autism and Intellectual Disability

This case study shows how an 8-year-old boy with autism and mild intellectual disability underwent positive psychological development in terms of play, social communication, and mentalization during a year and a half of group-based therapy using COMSI®-(COMmunication and Social Interaction). This eclectic treatment has a relational approach and is based on developmental psychology, knowledge of autism, and the impact of nature and animals on human health. The change in the child was been studied using both quantitative and qualitative methods. His general intellectual capacity was measured using the Wechler Preschool and Primary Scale of Intelligence, and his Mentalization Ability/Theory of Mind was assessed using three tests: Eva and Anna, Hiding the fruit and Kiki and the cat. Throughout the study period, change was documented with the help of the therapists’ process notes and the parents’ descriptions. The results show that support for the child comes from three different sources: nature, animals, and the therapists. Animals and nature form the basis for episodes of coordinated attention in conversation and play with therapists. The therapists’ approach used sensitivity and compliance with the child’s needs and focus of interest

Nature-assisted rehabilitation for reactions to severe stress and/or depression in a rehabilitation garden: long-term follow-up including comparisons with a matched population-based reference cohort.

Objective: To determine the effect of a nature-assisted rehabilitation programme in a group of patients with reactions to severe stress and/or mild to moderate depression. Changes in sick-leave status and healthcare consumption in these patients were compared with those in a matched population-based reference cohort (treatment as usual). Design: Retrospective cohort study with a matched reference group from the general population. Subjects: A total of 118 participants referred to a nature-assisted rehabilitation programme, and 678 controls recruited from the Skane Health Care Register. For both groups, information on sick leave was extracted from the National Social Insurance Register and on healthcare consumption data from the Skane Health Care Register. Methods: The interventional rehabilitation programme was designed as a multimodal programme involving professionals from horticulture and medicine. The programme was conducted in a rehabilitation garden, designed especially for this purpose. Results: A significant reduction in healthcare consumption was noted among participants in the programme compared with the reference population. The main changes were a reduction in outpatient visits to primary healthcare and a reduction in inpatient psychiatric care. No significant difference in sick-leave status was found. Conclusion: A structured, nature-based rehabilitation programme for patients with reactions to severe stress and/or depression could be beneficial, as reflected in reduced healthcare consumption

Perceived Sensory Dimensions of Green Areas: An Experimental Study on Stress Recovery

Natural environments have been shown to promote health, and are, therefore, important for achieving social sustainability in cities. As cities grow and become denser, it is important to develop knowledge about the characteristics of natural environments that work to promote health. Perceived Sensory Dimensions (PSDs) is a tool that defines eight different cultural ecosystem services. They correspond to different human needs (rest, exercise, socialising, pleasure, or security) resulting in rehabilitation and health and well-being promotion. An experiment was conducted to study the potential of PSDs to restore people who experienced stressful accidents. One hundred and fifty-seven participants were recruited and asked first to watch a film clip of serious accidents, then to look at the pictures, depicting one particular type of PSDs, while listening to its respective audio recording. Their stress levels were measured before exposure to the stressor (baseline), after exposure to the stressor (pre-test), and after exposure to a particular type of PSDs (post-test). The results show that all eight PSDs effectively provide mental recovery, but there are statistical differences in their potentials. As such, it is proposed that the combined potential of the PSDs is needed, and should be used to increase the capacity and supply of health-promoting urban green areas

The Oxytocinergic System as a Mediator of Anti-stress and Instorative Effects Induced by Nature: The Calm and Connection Theory

Ever more research results demonstrate that human health and wellbeing are positively affected by stays in and/or exposure to natural areas, which leads, among other things, to a reduction in high stress levels. However, according to the studies, these natural areas must meet certain qualities. The qualities that are considered to be most health promoting are those that humans perceive in a positive way. Theories about how natural areas can reduce people's stress levels and improve their coping skills have mainly focused on how certain natural areas that are perceived as safe reduce the activity of the hypothalamic-pituitary-adrenal axis and consequent reduction of cortisol levels. This article discusses studies containing descriptions of how participants in rehabilitation perceive and react to natural phenomena. The common core variable in the analyzed studies was the experience of calm and connection, and this experience was associated with a reduction in stress levels and with being able to develop health and coping skills. We suggest that this experience provides a possible role for the oxytocinergic system to act as a physiological mediator for the positive and health-promoting effects in humans caused by nature. The theory is mainly based on analogies framed by theories and data from the fields of environmental psychology, horticulture, landscape architecture, medicine, and neuroscience. Oxytocin promotes different kinds of social interaction and bonding and exerts stress-reducing and healing effects. We propose that oxytocin is released by certain natural phenomena experienced as positive to decrease the levels of fear and stress, increase levels of trust and wellbeing, and possibly develop attachment or bonding to nature. By these effects, oxytocin will induce health-promoting effects. In situations characterized by low levels of fear and stress in response to release of oxytocin, the capacity for "growth" or psychological development might also be promoted. Such an instorative effect of nature, i.e., the capacity of nature to promote reorientation and the creation of new coping strategies, might hence represent an additional aspect of the oxytocin-linked effect profile, triggered in connection with certain nature phenomena. We conclude by proposing that the stress-relieving, health-promoting, restorative, and instorative effects of nature may involve activation of the oxytocinergic system
