What does it take to renature cities? An expert-based analysis of barriers and strategies for the implementation of nature-based solutions.

This paper uses an expert-based methodology to survey the barriers and strategies related to the implementation of nature-based solutions (NBS). The ambition of the paper is to offer a bird's eye overview of the difficulties encountered by NBS deployment and ways to overcome them. With a wide participation of 80 experts from COST Action Circular City, we identify barriers specific to 35 pre-defined NBS of the following four categories: Vertical Greening Systems and Green Roofs; Food and Biomass Production; Rainwater Management; and Remediation, Treatment, and Recovery. The research sheds light on how a major interdisciplinary - yet predominantly technically-oriented - community of scientists and practitioners views this important topic. Overall, the most relevant barriers are related to technological complexity, lack of skilled staff and training programs and the lack of awareness that NBS is an option. Our results highlight concerns related to post implementation issues, especially operation and maintenance, which subsequently affect social acceptance. The paper identifies a "chain" effect across barriers, meaning that one barrier can affect the existence or the relevance of other barriers. In terms of strategies, most of them target governance, information, and education aspects, despite the predominantly technical expertise of the participants. The study innovates with respect to state-of-the-art research by showing a fine-grained connection between barriers, strategies and individual NBS and categories, a level of detail which is not encountered in any other study to date.

The local-global relationship of nature.

In the light of possible advance in the elucidation of emergence in natural systems we address the likelihood of an overriding relationship between the local and the global in Nature. We consider the possible views of an abstract conglomeration of entities, and whether a global representation can be established. This leads to a consideration of the problem in natural contexts to establish a relationship between local and global properties. We describe the application of a model-hierarchical representation to a biological cell, and its implications in terms of subjective and objective viewpoints. We conclude by stating the concluded relationship between local and global properties in Nature, in that control is exercised not only from local-to-global, but also from global-to-local.

Wilderness Is the Prototype of Nature Regardless of the Individual's Connection to Nature. An Empirical Verification of the Solastalgia Effect.

(1) Background: Connectedness with Nature is a personality trait that influences our relationship with Nature. But Nature is not all the same. Wilderness is Nature in its original form, the form within which human beings have evolved as a species, while what we refer to as domesticated and urban Nature are relatively recent products of our interaction with the environment. (2) Aim: The main purpose of this study was to verify whether the individual trait "connection to Nature" influences the perception of restoration, preference for and familiarity with three types of Nature: wilderness, domesticated and urban. (3) Results: Regardless of the level of connection to Nature, wilderness is always perceived as more restorative than the domesticated or urban environment. Individuals with higher connectedness prefer wilderness more than others, and they are able to recognise the restorative value of domesticated environments more than those with medium or low levels of connectedness. Less connected individuals tend to prefer domesticated environments, although wilderness is more familiar to them. (4) Conclusions: This study shows that, despite our detachment from Nature, wilderness is the prototype of Nature, and this finding offers a plausible evolutionary explanation of solastalgia.

The Beyond-Human Natural World: Providing Meaning and Making Meaning.

Much academic and media attention has been focused on how nature contributes to psychological health, yet, most of this focus has been on happiness or hedonic well-being. Although numerous writers and researchers have linked connecting with nature as a pathway to meaning in life, an integrated overview has not yet (to our knowledge) been offered. Our manuscript is thus of both theoretical and practical importance with respect to finding meaning in life. In this hybrid commentary/review paper, we examine the link between meaning in life and relating to the beyond-human natural world. Through presenting supportive empirical research and interdisciplinary insights, we make the case that connecting with the natural world provides us with meaning in various ways. We discuss how nature is a common source of meaning in people's lives and how connecting with nature helps to provide meaning by addressing our need to find coherence, significance/mattering, and purpose (the three aspects comprising the tripartite model of meaning life). We also consider how connecting with nature enhances our experiential appreciation for life, a fourth aspect of meaning in life recently proposed. Our discussion then expands to examining nature as a place of attachment. Going beyond how nature provides us with meaning, we consider how engaging in nature-based activities provides an avenue for many people to build meaningful lives. We close by considering how threats to nature are a threat to meaning in life.

Science and the legal rights of nature.

We review the use of science by lawmakers and courts in implementing or rejecting legal rights for nature in Ecuador, India, the United States, and other jurisdictions where some type of rights of nature have been recognized in the legal system. We then use the "right to evolve" to exemplify how interdisciplinary work can (i) help courts effectively define what this right might entail; (ii) inform how it might be applied in different circumstances; and (iii) provide a template for how scientists and legal scholars can generate the interdisciplinary scholarship necessary to understand and implement the growing body of rights-of-nature laws, and environmental law more generally. We conclude by pointing to what further research is needed to understand and effectively implement the growing body of rights-of-nature laws.

Nature visits during the COVID-19 pandemic in Norway: Facilitators, motives, and associations with sociodemographic characteristics.

Introduction: The COVID-19 pandemic has been linked to increased mental health issues and reduced well-being. Researchers also reports increased frequency of nature visits during the pandemic, proposing it may mitigate some of these negative consequences. Using the case of Norway, a country with ample access to nature and relatively low levels of pandemic-related restrictions, this study sought to (i) understand how the COVID-19 crisis impacted patterns of nature visits and specific nature-based activities, (ii) examine how these patterns varied among different population groups and levels of restrictions, and (iii) explore the motives and facilitators for increased frequency of nature visits. Methods: The data were retrieved from a national cross-sectional survey conducted in June 2021, which was designed to assess participants (n = 1,005, age > 15 years) habits in relation to nature visits and outdoor recreation since the beginning of the COVID-19 crisis, and associated factors. Results: The results showed that 32 % of participants increased their frequency of nature visits during the crisis, while 11 % experienced a decrease. Multivariate logistic regression revealed significant positive associations between increased frequency of nature visits and longer duration of lockdown restrictions (OR [95% CI] = 2.35 [1.28-4.29] and 4.92 [2.77-8.74] for a few weeks and several months of lockdown, respectively). Increased frequency of nature visits was also more likely among women, younger respondents, and individuals from high-income households. A Cochran's Q test showed that the most common motive for increased frequency of nature visits was "To be physically active" (74%). The most commonly reported facilitators were the possibility of using natural environments as an alternative to gyms and organized sports alongside having more time available (58 and 49%, respectively). Conclusion: These findings suggest that nature visits provided important opportunities for physical activity during the COVID-19 crisis, but also that the mental health benefits of nature visits during such times may be under-communicated. This highlights the importance of access to natural environments to promote physical activity and health, but also suggests that campaigns that specifically communicate the beneficial effects of nature visits during lockdowns or similar stressful situations might help people cope with the situation.

A Report on the Ke Ola O Ka 'Aina: 'Aina Connectedness Scale.

Optimal health from a Native Hawaiian worldview is achieved by being pono (righteous) and maintaining lokahi (balance) with all our relations, including our relationships as Kanaka (humankind) with 'Aina (land, nature, environment, that which feeds) and Akua (spiritual realm). The purpose of this study is to explore the role of 'Aina connectedness in Native Hawaiian health and resilience to inform the development of the 'Aina Connectedness Scale. Qualitative methods were conducted with 40 Native Hawaiian adults throughout Hawai'i. Three themes emerged: (1) 'Aina is everything; (2) Connection to 'Aina is imperative to health; and (3) Intergenerational health, healing, and resilience are reflected through intergenerational connectedness with 'Aina. Qualitative findings, supplemented with a scoping review of land, nature, and cultural connectedness scales, led to the development of the 'Aina Connectedness Scale, which examined the degree to which people feel connected to 'Aina, with implications for future research. 'Aina connectedness may address concerns related to health disparities that stem from colonization, historical trauma, and environmental changes and better our understanding of Native Hawaiian health by fostering stronger ties to land. Resilience- and 'Aina-based approaches are critically important to health equity and interventions that aim to improve Native Hawaiian health.

The Importance of the Outdoor Environment for the Recovery of Psychiatric Patients: A Scoping Review.

(1) Background: Research has shown that patients with mental health diagnoses experience less anxiety and depressive symptoms and higher levels of 'well-being' when they spend time in natural environments as part of their treatment. It has been suggested that there is a relationship between the outdoor settings and the recovery of psychiatric patients. Recovery describes an individual process, which can vary from person to person. (2) Methods: This scoping review examined the relationship between the physical environment and the recovery of psychiatric patients. Systematic searches in three online databases, namely Medline, Embase, and PsycINFO, were performed using a selection of psychiatric, environmental, and recovery terms and included both quantitative and qualitative studies. In general, 'well-being' serves as an overarching indicator when it comes to research on how outdoor settings can affect mental health. Well-being was expressed in terms of mood, social relations, and autonomy. (3) Results: A total of 8138 records were screened, 85 studies were included for full-text reading, and five articles were included in the final analysis. The review showed in general that outdoor settings, more specifically gardening, contact with nature, and a safe environment can be related to the well-being of patients on psychiatric wards. (4) Conclusions: The five reviews allow us to conclude that outdoor settings can be seen as a comprehensive resource for mental health.

Getting Out of the Classroom and Into Nature: A Systematic Review of Nature-Specific Outdoor Learning on School Children's Learning and Development.

Background: The value of natural environments for developing children's self-identity and social skills has been known for some time, and more recently the potential of nature-specific (i.e., excluding built environments) outdoor learning for achieving academic outcomes has been explored. Connecting children with natural spaces has been shown to benefit their physical and mental health; however, the utility of nature-specific outdoor environments as a setting for curricular and non-curricular learning has yet to be clearly established. Our aim was to undertake a narrative synthesis of international evidence of nature-specific outdoor learning and its benefits for personal and social development, wellbeing and academic progress. Methods: This systematic review searched publications between 2000 and 2020 in nine academic databases for evidence of socio-emotional and academic benefits of nature-specific outdoor learning in school-aged educational settings, using concise search criteria registered with PROSPERO. The total search results of 17,886 records were initially screened by title, and then two reviewers made blind reviews of the title and abstract of 1,019 records. Results: 147 original research studies meeting the criteria were identified. Learning settings ranged across outdoor adventure education, school gardens, field trips, and traditional school subjects taught in natural environments. Study characteristics were summarized, and risk-of-bias tools assessed quality of research as generally moderate, although with a wide range. The reported benefits of learning in natural outdoor settings include: increased student engagement and ownership of their learning, some evidence of academic improvement, development of social and collaborative skills, and improved self-concept factors. Conclusions: Nature-specific outdoor learning has measurable socio-emotional, academic and wellbeing benefits, and should be incorporated into every child's school experience with reference to their local context. Teacher pre-service and in-service education needs to include a focus on how natural settings can be used effectively for learning. Further research is needed to clarify the conditions under which specific forms of outdoor learning are most efficacious for various target outcomes. It is recommended that future studies measuring outdoor learning adopt established methodologies to improve the quality of research in this field.

Early warning of the Indian Ocean Dipole using climate network analysis.

SignificanceThe Indian Ocean Dipole (IOD), an air-sea coupled phenomenon over the tropical Indian Ocean, has substantial impacts on the climate, ecosystems, and society. Due to the winter predictability barrier, however, a reliable prediction of the IOD has been limited to 3 or 4 mo in advance. Our work approaches this problem from a new data-driven perspective: the climate network analysis. Using this network-based method, an efficient early warning signal for the IOD event was revealed in boreal winter. Our approach can correctly predict the IOD events one calendar year in advance (from December of the previous year) with a hit rate of higher than 70%, which strongly outperforms current dynamic models.

People's desire to be in nature and how they experience it are partially heritable.

Nature experiences have been linked to mental and physical health. Despite the importance of understanding what determines individual variation in nature experience, the role of genes has been overlooked. Here, using a twin design (TwinsUK, number of individuals = 2,306), we investigate the genetic and environmental contributions to a person's nature orientation, opportunity (living in less urbanized areas), and different dimensions of nature experience (frequency and duration of public nature space visits and frequency and duration of garden visits). We estimate moderate heritability of nature orientation (46%) and nature experiences (48% for frequency of public nature space visits, 34% for frequency of garden visits, and 38% for duration of garden visits) and show their genetic components partially overlap. We also find that the environmental influences on nature experiences are moderated by the level of urbanization of the home district. Our study demonstrates genetic contributions to individuals' nature experiences, opening a new dimension for the study of human-nature interactions.

MicroRNA Cues from Nature: A Roadmap to Decipher and Combat Challenges in Human Health and Disease?

MicroRNAs are small non-coding RNA (18-24 nt long) that fine-tune gene expression at the post-transcriptional level. With the advent of "multi-omics" analysis and sequencing approaches, they have now been implicated in every facet of basic molecular networks, including metabolism, homeostasis, and cell survival to aid cellular machinery in adapting to changing environmental cues. Many animals must endure harsh environmental conditions in nature, including cold/freezing temperatures, oxygen limitation (anoxia/hypoxia), and food or water scarcity, often requiring them to revamp their metabolic organization, frequently on a seasonal or life stage basis. MicroRNAs are important regulatory molecules in such processes, just as they are now well-known to be involved in many human responses to stress or disease. The present review outlines the role of miRNAs in natural animal models of environmental stress and adaptation including torpor/hibernation, anoxia/hypoxia tolerance, and freeze tolerance. We also discuss putative medical applications of advances in miRNA biology including organ preservation for transplant, inflammation, ageing, metabolic disorders (e.g., obesity), mitochondrial dysfunction (mitoMirs) as well as specialized miRNA subgroups respective to low temperature (CryomiRs) and low oxygen (OxymiRs). The review also covers differential regulation of conserved and novel miRNAs involved at cell, tissue, and stress specific levels across multiple species and their roles in survival. Ultimately, the species-specific comparison and conserved miRNA responses seen in evolutionarily disparate animal species can help us to understand the complex miRNA network involved in regulating and reorganizing metabolism to achieve diverse outcomes, not just in nature, but in human health and disease.
