Scaling up nature-based solutions for climate-change adaptation: Potential and benefits in three European cities

Many exemplary projects have demonstrated that Nature-based Solutions (NBS) can contribute to climate change adaptation, but now the challenge is to scale up their use. Setting realistic policy goals requires knowing the amount of different NBS types that can fit in the urban space and the benefits that can be expected. This research aims to assess the potential for a full-scale implementation of NBS for climate-change adaptation in European cities, the expected benefits and co-benefits, and how these quantities relate to the urban structure of the cities.We selected three case studies: Barcelona (Spain), Malmö (Sweden), and Utrecht (the Netherlands), and developed six scenarios that simulate the current condition, the full-scale implementation of different NBS strategies (i.e., installing green roofs, de-sealing parking areas, enhancing vegetation in urban parks, and planting street trees), and a combination of them. Then we applied spatially-explicit methods to assess, for each scenario, two climate change-related benefits, i.e. heat mitigation and stormwater regulation, and three co-benefits, namely carbon storage, biodiversity potential, and overall greenness. Finally, by breaking down the results per land use class, we investigated how the potential and benefits vary depending on the urban form.Most scenarios provide multiple benefits, but each one is characterized by a specific mix. In all cities, a full-scale deployment of green roofs shows the greatest potential to reduce runoff and increase biodiversity, while tree planting -either along streets or in urban parks– produces the greatest impact on heat mitigation and greenness. However, these results entail interventions of different size and in different locations. Planting street trees maximizes interventions in residential areas, but key opportunities for integrating most NBS types also lie in commercial and industrial areas. The results on the pros and cons of each scenario can support policy-makers in designing targeted NBS strategies for climate change adaptation.     

Does time spent on visits to green space mediate the associations between the level of residential greenness and mental health?

ObjectiveThe objective of the current study was to explore whether time spent visiting green space near home acts as a mediator in the association between level of residential greenness and perceived mental health.MethodsQuestionnaire data and satellite data of residential greenness were gathered in four European cities (total n = 3748): Barcelona (SP), Doetinchem (NL), Kaunas (LT) and Stoke-on-Trent (UK).ResultsMediation analyses showed that time spent visiting green space near home was a weak, but statistically significant, mediator in the pooled data and in the Dutch sample only.ConclusionsThe findings provide little support for the hypothesis that purposeful visits are a mediator linking indirectly greenness with mental health. More research is needed to explore other mediators related to different exposure pathways, such as visual exposure, and alternative mechanisms, such as (perceived) safety.     

Development of the natural environment scoring tool (NEST)

Natural environments (green and blue space) are associated with a range of health benefits, but their use is likely to be influenced by the presence of features, facilities and amenities and the condition/maintenance, or the natural environment quality. Most ‘quality’ assessment tools have focused on green spaces and their support for physical activity. This limits their utility for assessment of other natural environment typologies and uses (e.g., social, relaxation). We aimed to develop a tool for feasible, in situ assessment of diverse natural environments that might support a variety of uses, and to explore associations between natural environment quality and objectively measured amount of natural environment and neighbourhood-level socio-economic status (SES).This work was conducted as part of the PHENOTYPE project. Data were collected in 124 neighbourhoods in four European cities (Barcelona, Doetinchem, Kaunas, Stoke-on-Trent). The Natural Environment Scoring Tool (NEST) was developed using existing tools, expert input and field-testing. The final tool comprised 47-items across eight domains: Accessibility, Recreation facilities, Amenities, Aesthetics − natural, Aesthetics – non-natural, Significant natural features, Incivilities and Usability; typology-specific Overall Scores were derived.In total, 174 natural environments, covering a range of typologies, were audited. Mean time to complete NEST was 16 ± 28 min. There was good inter-rater agreement. Mean domain scores showed some expected patterns by typology (e.g., higher Recreation Facilities scores in urban parks and formal recreation areas; lower Amenities scores in natural/semi-natural areas). Highest mean Overall Scores were observed for areas of blue space and woodland, the types of area that often lack the recreational facilities or amenities that can be dominant in physical activity-focused audit tools. There was a trend towards lower natural environment quality in neighbourhoods of lower SES, with some inter-city variation. Correlations between NEST scores and amount of natural environment indicated higher natural environment in areas with worse access. We recommend further testing of NEST in other locations in relation to use and health outcomes.     

Crisis mediated new discoveries,claims and encounters: Changing use and perception of residential greenery in multistory housing in Berlin,Germany

With the stay at home orders during the pandemic, the often semi-public green spaces of the residential environment, usually created during the building of the houses, became our literal spheres of experience. In our study, we explored use and perceptions of local greenery by residents after sixteen months of the COVID-19 crisis, using face to face questionnaires in eight socially disadvantaged neighborhoods of Berlin, all exposed to high loads of environmental stressors and belonging to four relevant building types of Central European cities. Residential greenery was highly appreciated by residents during COVID-19, and fostered a more active appropriation such as meeting neighbors to reduce the sense of loneliness, doing sports and co-creating refugia in challenging times (e.g. greened balconies). Having children or doing home office/schooling encouraged people to use the green in front of the door in more active ways, such as gardening or even during winter. A minor proportion of respondents reduced contacts mainly due to fear of infections, underlining the need to overcome those distances and to re-connect neighbors and living inside and outside the houses in a post-pandemic city. Our data prove the functionality of residential greenery as ‘social tissue’ or ‘social hubs’ of neighborhoods by fostering attachment to place and people and, at the same time, as healthy environment for practices such as enjoying nature and physical activity in fresh air.     

Urban wilderness: Supply,demand, and access

The concept of urban wilderness feels like a paradox since natural and urban environments have long been viewed as antithetical. Today, however, wilderness is high on the urban agenda as a response to different challenges: biodiversity and human experiences of nature are being lost in increasingly dense cities, while at the same time a plethora of wild areas are developing in cities that are undergoing post-industrial transformation. Yet there is confusion around the definitions and the anticipated functions of urban wilderness and how humans can be incorporated therein. A unifying framework is proposed here that envisions urban wilderness as a social-ecological system; three major components are identified and linked: (i) the supply of wilderness areas along gradients of naturalness and ecological novelty, leading to a differentiation of ancient vs. novel wilderness, and the identification of wilderness components within cultural ecosystems; (ii) the demand for wilderness in urban societies, which differs among sociocultural groups as a function of underlying values and experiences; (iii) the access to urban wilderness, which can be improved both in terms of providing opportunities for encountering urban wilderness (e.g., by conserving, rewilding wilderness areas) and enhancing the orientation of urban people towards wilderness (e.g., through information, environmental education, citizen science). Evidence from urban wilderness projects in Europe demonstrates that multi-targeted approaches to conserving and managing existing novel urban ecosystems offer manifold opportunities to combine biodiversity conservation and wilderness experience in cities.     

Landscape planning and stress

Stress and stress-related illnesses, as reflected in medical records, have increased dramatically among adults and children in Western societies. A growing part of the budget for medical service in Sweden is used for individuals suffering from different stress-related illnesses such as burnout syndrome, insomnia and fatigue, depression, feelings of panic, etc. In this paper, we present results from a study in which 953 randomly selected individuals in nine Swedish cities answered a questionnaire about their health and their use of different urban open green spaces in and close to the city.The results indicate that city landscape planning may affect the health of town-dwellers. Statistically significant relationships were found between the use of urban open green spaces and self-reported experiences of stress – regardless of the informant's age, sex and socio-economic status. The results suggest that the more often a person visits urban open green spaces, the less often he or she will report stress-related illnesses. The same pattern is shown when time spent per week in urban open green spaces is measured.The distance to public urban open green spaces seems to be of decisive importance, as is access to a garden, in the form of a private garden or a green yard immediately adjacent to, for instance, an apartment building. People do not usually compensate for lack of green environments in their own residential area with more visits to public parks or urban forests.According to our results, laying out more green areas close to apartment houses, and making these areas more accessible, could make for more restorative environments. Outdoor areas that provide environments free from demands and stress, and that are available as part of everyday life, could have significant positive effects on the health of town-dwellers in Sweden. This may also apply to other Western societies.     

Where to construct new urban green spaces to be at the recommended distance from users and to complement existing ones? A study in five cities of northern Portugal

The proximity to urban green spaces (UGS) is important to facilitate their use by citizens, mainly by the most vulnerable groups in society who are usually unable to walk long distances. Furthermore, there are several ecosystem services from which the population can only benefit if UGS are close. In addition to being important to identify areas without a UGS nearby, it is also important to indicate possible locations for a new UGS, thus avoiding wasting resources by overlapping coverage areas or leaving gaps in coverage. It is also important to understand among all possible locations where the construction of a UGS is most needed. The present study aims (i) to identify possible locations for future UGS and order them by construction priority, (ii) to develop and test a methodology for decision-makers and urban planners and (iii) to contribute to increasing and developing UGS in cities. Considering residential areas, the results reveal a deficiency in UGS coverage in all the cities studied, as only 43.86–57.09% of residential areas have a UGS within 300 m. Construction of proposed UGS will lead to a 12.30–26.15% increase in coverage. The proposed methodology needs further improvement, but it can be a valuable tool for urban planners and decision-makers, and can encourage the construction of more UGS.     

Challenges of urban green space management in the face of using inadequate data

Effective urban planning, and urban green space management in particular, require proper data on urban green spaces. The potential of urban green spaces to provide benefits to urban inhabitants (ecosystem services) depends on whether they are managed as a comprehensive system of urban green infrastructure, or as isolated islands falling under the responsibility of different stakeholders. Meanwhile, different urban green space datasets are based on different definitions, data sources, sampling techniques, time periods and scales, which poses important challenges to urban green infrastructure planning, management and research. Using the case study of Lodz, the third largest city in Poland, and an additional analysis of 17 other Polish cities, we compare data from five publicly available sources: 1) public statistics, 2) the national land surveying agency, 3) satellite imagery (Landsat data), 4) the Urban Atlas, 5) the Open Street Map. The results reveal large differences in the total amount of urban green spaces in the cities as depicted in different datasets. In Lodz, the narrowly interpreted public statistics data, which are aspatial, suggest that green spaces account for only 12.8% of city area, while the most comprehensive dataset from the national land surveying agency reveals the figure of 61.2%. The former dataset, which excludes many types of green spaces (such as arable land, private and informal green spaces), is still the most commonly used. The analysis of the 17 other cities confirms the same pattern. This results in broader institutional failures related to urban green infrastructure planning, management, and research, including a lack of awareness of green space quality (e.g. connectivity) and benefits (ecosystem services), and the related political disregard for urban green spaces. Our comparison suggests that a better understanding of green space data sources is necessary in urban planning, and especially when planning urban green infrastructure.     

Do perceived walking distance to and use of urban blue spaces affect self-reported physical and mental health?

A cross-sectional analysis among 1041 urban residents was done to examine associations between self-reported walking distance to and use of freshwater urban blue space and health-related quality of life in two German cities: a city with “poor” urban blue space supply (Bielefeld; 0.8% blue space) and one with “better” urban blue space supply (Gelsenkirchen; 3.0% blue space). Health-related quality of life was assessed with the SF-12v2, which measures residents’ self-reported mental and physical health. Results showed a significant association between use frequency and perceived walking distance to blue space. Blue space use was a better indicator of health outcomes than perceived walking distance. After controlling for green space, socio-economic and demographic variables, use frequency was associated with higher mental health in Gelsenkirchen. These cross-sectional findings suggest that blue space use increases the probability of being healthier in highly urbanised areas in cities with an appropriate amount of blue space.     

Emotional perceptions of people exposed to green and blue spaces in forest parks of cities at rapid urbanization regions of East China

Urbanization modifies the landscape with green and blue spaces (GBS), which further leads to a functional change along an urban-rural gradient. Emotional improvement is a critical service of GBS, which may be perceived and exposed through facial expressions by visitors. How people react, however, may vary at different locations of a city at varied phases of urbanization. In this study, happy and sad emotions were rated as scores from 7965 Sina-Weibo users who visited 77 GBS across 49 cities of East China in 2020. GBS were located in different regions of a city, either near downtown or in more rural-like regions. Compared to cities near the Hu Huanyong line, those along the eastern coast were built with parks that had smaller green spaces at lower elevations in locations near downtown. They also had larger blue spaces in parks at suburban areas of the same cities. People expressed more happiness in GBS in regions closer to remote rural regions, or in cities further from the eastern coast. Larger green spaces were associated with by the presentation more smiles in parks near downtown, while experiences in large blue spaces evoked positive emotions at suburban areas. Overall, GBS in population-dense regions of more developed cities can be perceived as an activation of exposing higher depression by visitors. More smiles can be exposed in GBS with a large green space near downtown, or with a large blue space at suburban regions of a city in East China.     

Responses of four hornet species to levels of urban greenness in Nagoya city,Japan: Implications for ecosystem disservices of urban green spaces

Although there is a common trend towards increasing green space in modern cities, urban green spaces provide not only ecosystem services but also disservices for urban dwellers. However, the relationship between urban greenness and ecosystem disservices has been poorly examined. We aimed to understand the effect of greenness level on the abundance and species composition of hornets – critical pests in Japan and to identify the best spatial scale for estimating their abundance with reference to greenness levels. We used a dataset that contained eight years of abundance data for four hornet species at 11 sites in Nagoya city. The levels of greenness around the hornet sampling points were measured using averages from the Normalized Difference Vegetation Index (NDVI) with radiuses of 0.1–10.0 km. We analysed the relationship between abundance and species composition of hornets and NDVI at different spatial scales using generalized linear mixed models. Higher NDVI values positively affected the abundance of all the hornet species except Vespa analis. The abundances were estimated most effectively using the NDVI average with a 1–2 km radius for all species. The species composition of hornets drastically changed along the gradient of NDVI values; V. mandarinia was dominant in greener areas (over 0.2–0.3 NDVI average with a 2 km radius) and V. analis in less green areas (below 0.2–0.3 NDVI average). Our study showed that the abundance and species composition of hornets were both strongly associated with the level of urban greenness. This suggests that increases in the greenness of urban areas can increase hornet abundance and alter the species composition of hornets; a more aggressive species, V. mandarinia, may also increase in urban areas, although V. analis is currently the most critical species according to regional consultants. Balancing ecosystem services and disservices has become crucial for the planning and management of green spaces, particularly when urban green space increases. We also demonstrate how human tolerance towards wildlife may have to be improved in order to live in greener environment where wildlife can be expected.

The association between plant diversity and perceived emotions for visitors in urban forests: A pilot study across 49 parks in China

Urbanization introduces uncertainties to the biodiversity of plant communities. The perception of biodiversity can be associated with positive mental health and well-being, but direct evidence is still insufficient. In this study, we collected data about plant biodiversity assessments from studies on urban forests in the literature of China’s national knowledge infrastructure. Records of the species amount, Shannon index, and Simpson index were extracted from 49 urban forest parks in 13 cities across mainland China from 2018 to 2021. A total of 1938 facial photos were obtained from microblogs with check-in locations at these parks in the Sina Microblog in 2020. Happy, sad, and neutral emotions and positive response index (PRI; happy minus sad) were rated and mapped for spatial distributions. The amount of species was distributed as a heterogeneous pattern for all plant types, and biodiversity was higher in the northern regions (e.g., ~55% in Qingdao and over 50% in Taiyuan) than in southern cities along the Yangtze River (e.g., ~35% in Huaihua and Changsha). Trees did not account for the association of biodiversity with emotional expressions. Smiles were elicited mostly in parks with more diverse shrubs (Shannon index: R=0.4335; P = 0.0029) and herbs (R=0.6162; P = 0.0008). Females showed more smiles than males (47% vs. 32%, respectively; F=39.15, P < 0.0001), and happy emotions tended to be higher in older visitors (senior vs. younger: 58% vs. 43%, respectively; F=2.72, P = 0.0280). Overall, we recommend visiting parks in northern cities of China for the benefit of evoking positive emotions through experiencing abundant undergrowth species. Female visitors would benefit more than males in the promotion of mental well-being by perceiving diverse shrubs and herbs in urban forest parks.     

Inequalities in the quality and proximity of green space exposure are more pronounced than in quantity aspect: Evidence from a rapidly urbanizing Chinese city

Substantial studies have revealed that exposure to green spaces (GSs) yields a variety of health benefits. However, daily GS exposure scenarios are multidimensional, and relevant analyses require a comprehensive framework that assesses GS exposure from overhead- to eye-level perspectives, focusing on GS attributes from quantity and proximity to quality. Moreover, GSs are often unevenly distributed across cities, resulting in green distribution injustice. To this end, this study aimed to systematically evaluate multiple GS exposures considering two-dimensional (2D) spatial exposures (i.e., quantity-based availability, distance-based accessibility, and quality-based attractiveness) and three-dimensional (3D) visual exposures (quantity-based street GS visibility and quality-based street GS perceivability). It then examined the inequalities in GS exposure among socioeconomically disadvantaged groups. Housing prices were employed as proxies for socioeconomic status. Local indicators of spatial association(LISA) were employed to examine the existence of bivariate statistically significant spatial clusters of housing prices and multiple GS exposure. Furthermore, the spatial lag regression model was used to determine inequities in GS exposure among urban residents living in communities with different housing prices. The Nanjing metropolitan area, one of the most densely populated cities in China, was selected as the study case. Residential exposure to GS was comprehensively assessed using a 15-min walkable zone lens. The results suggest that: 1) the spatial cluster of ‘low GS exposure – low housing price’ occupied the largest proportion; 2) all five types of GS exposure were positively associated with housing prices, indicating that the affluent groups are more likely to have access to various GSs; and 3) GS exposure inequalities are more pronounced in measurements of quality(and proximity) than quantity in both spatial and visual exposure metrics. These findings can inform the development of environmental planning and policy strategies for more effective, efficient, and equitable GS provisions that address health issues and green injustice in rapidly urbanizing cities.     

Envisioning the future—Creating sustainable,healthy and resilient BioCities

Numerous challenges – from population increase to climate change – threaten the sustainable development of cities and call for a fundamental change of urban development and green-blue resource management. Urban forests are vital in this transition, as they provide various ecosystem services and allow to re-shape and re-think cities. Based on a Europe-wide community effort with diverse experts centered around urban forests and urban greening, we propose five key research fields to generate the knowledge required to unlock fundamental changes in urban development and green-blue resource management: circular bioeconomy, climate resilience, governance, social and human environment, and biodiversity. To support the design of greener, cooler, more inclusive and resilient cities, all these research fields require inter- and transdisciplinary collaboration, engaging stakeholders in transforming urban engagement and functioning. We summarise main inter-, trans- und multi-disciplinary research paths for each field and the cross-cutting knowledge areas that can help to address the challenges many cities face (e.g., modelling and assessment of the urban microclimate). For transforming cities further knowledge is needed on e.g., urban innovation, transition, participation, and more. Finally, we address how the identified research gaps can be implemented (e.g., international coordinated research effort, interdisciplinary networks).     

Visual structure of landscapes seen from built environment

Vegetation in cities keeps climate warming down and improves the health of people and ecosystems while making for a pleasant urban setting. Contemporary urban planning promotes sustainable green cities. Green and blue infrastructures, which help maintain an eco-friendly environment, are the primary instruments of this movement. This paper attempts to show the relative weight of plant life (trees, grass, orchards, etc.) seen from buildings in different urban settings (local urban patterns of high or low density of buildings). Landscapes open to view are identified by combining a digital elevation model and an 11-class land-use layer (including buildings, facilities, grey infrastructures, green and blue surfaces) in a computational tool that calculates viewsheds. The results show that vegetation is very much present in urban landscapes. In high-density built areas of city centres, the landscape is varied although not open and is dominated by trees, low-rise residential buildings and grass. Grey infrastructures and bushes are also very common. In low-density built areas the rank order of objects in view is similar but the landscape is more panoramic.     

Residents’ preferences for cultural services of the landscape along the urban–rural gradient

Cultural services of the landscape contribute to a higher quality of life. The provision of these services differs along the urban–rural gradient, as does their appreciation by local residents. This paper investigates residents’ preferences for cultural services along the urban–rural gradient through a map-based survey in and around the Dutch city of Maastricht. We focus on the importance of location in explaining these preferences, distinguishing the location of residents (relative to the preferred landscape units) and the location of landscape units (relative to their positions on the urban–rural gradient). The study shows that residents prefer nearby locations for all distinguished cultural services. Locations’ valuation along the urban–rural gradient, however, differs by service type: for cultural heritage locations near the city centre are preferred, while outdoor recreation and sports and passive enjoyment of green landscapes are enjoyed more in rural areas. When considering the spatial distribution of the land-use types that provide these services, we further find that people prefer green areas closer to the city for outdoor recreation and sports and passive enjoyment of green landscapes. The results illustrate the heterogeneity of people’s preferences for cultural services along the urban–rural gradient beyond the distance from their residences. We recommend policy makers to take the urban–rural gradient into account when valuating landscape units, and in particularly the importance of green landscape units close to the city for different cultural services.     

Public green spaces and human wellbeing: Mapping the spatial inequity and mismatching status of public green space in the Central City of Shanghai

Public green spaces are fundamental and indispensable to urban settlements, given the diverse social, economic and environmental benefits that they can provide. However, the absence of knowledge regarding the allocation and access status quo consistently hinders the suitability and rationality of follow-up green space planning, which could eventually impair the livability and sustainability of cities. This study evaluates disparities in access to public green space for urban residents and the spatial mismatches among public green space provision, residents’ visits and the demands of socially vulnerable groups within the Central City of Shanghai. The results show that disparities in public green space accessibility exist pertaining to social status and household composition status. Sub-districts with higher social status or larger proportions of family households composed by children and married inhabitants tend to have better public green space access. In contrast, sub-districts with larger proportions of aged or unemployed populations unexpectedly show worse public green space access. To a certain degree, this reduced access can be considered to be an environmental injustice. Additionally, the mismatches among public green space provision, residents’ visits and the demands of socially vulnerable groups are observed to vary in space, indicating potential problems of resource shortage, supply-demand mismatch, underuse and congestion. The findings could offer urban planners and policy-makers insights into optimizing public green space resources and equitably providing proximal public green space to urban residents, especially vulnerable groups, such as children, the elderly and the unemployed.     

Connection to nature and time spent in gardens predicts social cohesion

A person’s health and wellbeing are contingent on the amount of social support that they receive. Similarly, experiencing nature has been shown to improve people’s health and wellbeing. However, we do not know how relationships between social cohesion, nature experiences and nature connection could interrelate and vary across different types of urban green spaces, and in non-Westernised cultures. We conducted a study on 1249 residents in Singapore, a tropical city-state, and measured three dimensions of social cohesion (i.e. general social cohesion; trust and sense of community; and social interactions), various types of nature experiences (i.e. amount of green space around one’s residence; frequency and duration of urban green space visits; frequency and duration of visits to gardens), and three dimensions of one’s connection to nature: self-identity with nature, desire to experience nature, and environmental concern (using the nature relatedness scale). We found that people who strongly identify with nature, who enjoy being in nature, and who had more frequent gardens visits were more likely to have a stronger sense of social cohesion across two dimensions. However, those with stronger environmental concern reported an overall weaker sense of social cohesion, possibly due to the perception that society’s contributions to conserve environmental problems was insufficient. Further, people who gardened more frequently were also more likely to visit green spaces, self-identify with nature and exhibit a stronger desire to experience nature. We propose that strategies targeted at encouraging people to engage in nature-related, collaborative activities at the local community level, such as spending time in local gardens, will increase urban residents’ daily nature experiences and its associated benefits such as improving social cohesion.     

Needs and expectations of German and Chinese children for livable urban green spaces revealed by the method of empathy-based stories

One of the important features of cities is to provide high-quality outdoor environments for various groups of citizens. Although children are frequent users of green spaces, the knowledge and perspectives applied in planning and design of urban green spaces are mostly defined by adults. This results in spaces and practices that may limit the daily lives and creativity of urban children. Promoting child-friendly cities benefits from knowledge produced by children themselves, regarding their perceptions and experiences, as well as ideas and suggestions. This study provides empirical results concerning children’s needs and mental images for urban green spaces in two urban areas in two countries (Chengdu, China, and Ruhr Region, Germany). 765 children, ages 8–10 were surveyed through the method of empathy-based stories (MEBS). Participants were asked to use their imagination to write stories according to given scenarios. Our study shows that MEBS can be used to gather meaningful data with children, and that children are an important stakeholder group in urban planning, landscape design and management with an ability to express their diverse needs and preferences towards green spaces. Both designed green spaces (e.g. gardens, parks) and wild nature (e.g. forests, meadows) can offer a range of activities and experiences for children in their everyday lives: opportunities for play, socializing, contact with nature, aesthetic and restorative experiences, learning and exploration. Our findings include indications of children’s awareness of the diverse ecosystem services that green spaces provide, as well as of urban sustainability and livability. While we found German and Chinese children to have corresponding needs and expectations regarding urban green spaces and nature, we also found some variation. We suggest that the use of, and experiences in green spaces are linked not only to the landscape but also to conceptual-cultural contexts.
