The assessment of ecosystem services (ES) in urban areas can be an important policy instrument for both strategic directives at national and regional levels and concrete actions at municipality level. A unifying underpinning framework that combines different administrative levels through a common, consistent basis would greatly facilitate the mainstreaming of such an instrument. Three key concepts underpin this framework: urban ecosystems, nature-based solutions (NBS), and ES. First, NBS are acknowledged as the ecological assets that in the urban context can provide ES, meant as complex processes made possible through the existence of natural and seminatural systems at various scales. Second, the classification of urban ecosystems needs to be consistent with the treatment of urban areas in ecosystem accounting and with NBS levels of intervention and primary objectives. Third, by serving societal challenges, it is important to clearly frame the strategic drivers of change: whether it concerns management practices of current land use or radical conversions in land use. Finally, once such a framework will be in place, it can facilitate sustainability assessment in urban ecosystems by quantifying the presence of NBS, whose creation/maintenance assure the delivery of ES. The purpose of this chapter is to theoretically frame an ES-based approach, but this is only a first step. Many more steps are required on to concretely put this framework in practice at different administrative levels, such as strategic planning and policy setting (at national level), and urban, peri-urban, and coastal development (at municipal level).

While concentration of population in urban areas continues, limited contact with ecological dynamics undermines awareness on human dependence on ecosystems. However, demands on ecosystems have never been higher than in today's urbanized planet, and cities make major contributions to global environmental problems. Enhancing green and blue infrastructure (GBI) in cities can reduce the ecological footprints of cities, while enhancing urban resilience and quality of life for their inhabitants. Urban GBIs provide multiple benefits to people in the form of ecosystem services (ES) and hold potential for providing nature-based solutions (NBS) to address urban challenges.

To adequately evaluate the ES provided by GBI, researchers have recently advocated integrated valuations. Integrated valuations aim at overcoming the limitations of the traditional single discipline and narrow approaches, by considering the multiple ways in which humans benefit from nature across the economic social and cultural domains.

In this chapter, we present examples of integrated valuations of ES in two Spanish cities, Barcelona and Bilbao. Both examples combine different valuation techniques and metrics, both monetary and nonmonetary, to account for the ES provided by urban GBIs and to assess their potential as NBS.

Our case examples show that urban GBIs provide many valuable benefits to urban dwellers. One of the clearest outcomes from these infrastructures is cultural ES, especially the multiple recreation and leisure opportunities they provide, which in turn has a remarkable positive effect on human health and well-being.

Land‐use and cover change threatens remaining urban green areas and the provision of ecosystem services. The purpose of this paper is to address the importance, sufficiency and needs of local recreational ecosystem services in urban areas.

The case study area is the City of Helsinki, Finland. In total, 30 key informants representing 19 neighbourhood associations in the urban‐rural gradient within the city were interviewed.

The results of the Helsinki case show that residents visit the focused nature areas frequently and spend considerable amount of time there. All the mentioned activities during visits were associated with getting recreational experiences. Of these the most frequently mentioned were getting “feel‐good feeling” and physical exercise, which were closely associated with walking and sports‐like activities. The importance of easy accessibility to local nature areas was emphasized. Recreational ecosystem services partly result from specific landscape features in the nature area and from biologically diverse nature.

Planners, managers and decision makers can use the findings from this study in determining the values of similar urban green areas in urban development.

The Helsinki case shows that these local nature areas are appreciated and attractive and that the residents of the focused study areas perceive the numerous benefits that the local nature areas provide as very important. It appears that conserving a considerable amount of remnant nature amongst urban housing has paid off in flourishing recreational ecosystem services in the studied area.

Sacred forests are biocultural landscapes deeply rooted in centuries-old traditions of spiritual veneration. These sacred sites, including shrines, temple forests churches and graveyards, have historically been significant reservoirs of traditional resource management practices underpinned by spiritual reverence. However, despite their cultural and ecological importance, the cultural ecosystem services inherent to these sacred forests remain unexplored, particularly in urban settings.

This study focused on six sacred sites within Kanazawa City, Japan, using a meticulous face-to-face survey with 342 participants. We collected data on the extent of forest utilisation, the breadth of activities engaged in by visitors and their holistic appraisal of the rendered cultural ecosystem services. The findings illustrate the multifaceted benefits of urban sacred forests, encompassing participation in religious ceremonies, cultural events and festivals, complemented by educational programming that elucidates the historical and traditional underpinnings of the shrines and their surrounding communities.

It has been observed that urban forests have a crucial role in providing spiritual and communal connectivity, preserving traditional heritage, offering vital aesthetic values as green spaces and making visitors connected with nature while they are in the urban landscape. However, a concerning trend has emerged, as the younger demographic appears to lack interest in participating in the stewardship and cultural activities associated with these biocultural landscapes. Community engagement strategies must be strengthened, conservation measures should be implemented and cultural awareness programs need to be established to ensure the perpetuation and appreciation of these valuable urban sacred forests.

This study provides original perspectives on the measurable cultural ecosystem services and intangible values associated with urban sacred forests using the sacred forests in Kanazawa City, Japan. Our research illuminates the various advantages that visitors derive by examining the intersection of spiritual traditions, resource management practices and cultural significance, which has been relatively unexplored. The present study provides a significant basis for establishing initiatives that seek to promote the cultivation of respect and responsibility towards urban sacred forests.

Urbanization is characterized mainly by changes in land use and conversion of natural areas into built environments, as well as by a series of impacts, such as loss of biodiversity, which interfere with the proper functioning of ecological networks.

Thus, the authors apply a bibliometric analysis using the term “Urban Trees” in the “Web of Science” database, between 2009 and 2019, as a keyword to include all urban green structures and identify the main aspects of urban ecological relationships. They found 8,367 published articles.

This review identified the main countries and research institutions that operate in urban afforestation. In general, developing countries seek to understand the environmental benefits that urban afforestation can provide, demonstrating the importance of maintaining existing green areas in urban centers to promote the balance of the ecosystem. It depends directly on the flow of ecosystem services provided by green infrastructures in the city, contributing significantly to carbon sequestration, retention of particulate matter, mitigation of heat islands and reduction of surface runoff, directly favoring the health and well-being of the population. The authors conclude that the actions currently implemented in urban afforestation, especially to increase the richness and abundance of species, will be decisive for the future of urban centers and the construction of more sustainable and egalitarian cities.

This work sought to develop a bibliographic research based on information obtained by bibliometric analysis that has the ability to identify trends and volumes of scientific production in a given area of knowledge.

With rapid urbanization, cities are facing various ecological and environmental problems. Living in harmony with nature is more important than ever. This paper aims to evaluate the ecosystem and ecological features of Azheke village, a key component of the Hani Rice Terraces World Cultural Heritage in China. The focus is on exploring effective ways to improve the relationship between humans and the natural environment through urban design in order to create a livable and sustainable city that can promote the development of sustainable smart urban ecology design.

This study conducted a systematic literature review to answer the following research questions: (1) How does Azheke design achieve harmony between humans and nature? (2) What are the effective approaches to improve the relationship between humans and nature within urban ecosystems? (3) How can urban design learn and integrate from Azheke’s ecological features to improve the relationship between humans and nature?

Azheke sustains long-term human-nature harmony through traditional ecological knowledge (TEK) and efficient natural resource use. By incorporating biophilic design and nature-based solutions from Azheke, along with biodiversity-friendly urban planning, we can boost urban ecosystem health and create unique Azheke-inspired urban designs.

This research primarily focuses on the human-nature relationship, exploring design strategies based on biodiversity without delving into the interactions between other components of urban ecosystems, such as social-cultural and economic components.

This paper provides a new perspective and strategies for developing sustainable and smart urban ecology design. These findings can provide theoretical references for urban planners, designers and decision-makers.

The economic valuation of the ecosystem services (ES) provided by nature-based solutions in cities is not an easy task. In fact, various environmental goods and services do not have a market price that allows to quantify their value. This leads to an underestimation of the value of nature in cities. As a result, their critical contributions are not considered in public, corporate, and individual decision-making. The logic behind ecosystem valuation is to unveil the complexities of socioecological relationships, to make explicit how human decisions would affect ES values, and to express these value changes in units. This will allow considering the benefits provided by ES in public decision-making processes. The contribution aims to identify and analyze the most used methodologies adopted at the urban level for the valuation of ES. In total, six methodologies have been analyzed for the valuation of the provisioning, regulating, cultural, and supporting services. Finally, an interpretation framework has been defined to summarize the main findings.

The chapter tries to trace the development of concept of urban ecosystem as a problem-solving approach for urban problems, including the unwarranted problems caused by climate change. Urban management has increasingly shifted from infrastructure-based to a more regional-based approach. There has been a shift in the domain of urban ecosystem as well, from the established urbanized area to the aggregation of urban and surrounding rural area. Also, urban-rural linkages are given more attention in resource management in urban areas, thereby reducing the overall risk due to climate change. The chapter provides examples and challenges of urban ecosystem management from across the world.
