The objective of this paper is to provide an overall perspective on peri-urban ecosystem services in European Countries. The phenomenon of urbanization affecting our era has seen the shift of the city from compact and well-defined structures to agglomerations with a seamless expansion. This has led to several environmental consequences that have affected the urbanized areas and the surroundings. The peri-urban areas may be the main urban design and planning challenge of the 21st century. These hybrid landscapes, characterized by high fragmentation, can be turned into opportunities to improve the sustainability and quality of urban areas, generating multiple economic, social and environmental benefits. Areas beyond the immediate urban core can be considered a zone of influence, which represent a critical resource in terms of provisioning, regulating, supporting services and cultural ecosystem services. Our study has been developed in the framework of the project “Fertile Lands, Fragile Lands” funded by the University of Catania. A multi-phased method has been applied, showing strong, heterogeneous ties between landscape and ecosystem services. While the importance of literature studies on this topic is well recognized, the same attention has not been placed on the tools and methods of conducting systematic and incremental literature reviews. Using Leximancer software, we propose a text mining approach to extract relevant themes and concepts as well as related topics of interest from identified literature on peri-urban ecosystems. We first introduce the overall methodology and then discuss each phase in detail. The outputs can be used as starting point for broad exploratory reviews and allow further exploration in this issue. The results show how the peri-urban space can be seen as a mosaic in which the settlement, the agricultural and the environmental systems interact and coexist, placing at the centre the relationship of reciprocity between the built environment and the open territory.

Physical Components

Urban ecosystems are composed of biological components (plants, animals, microorganisms, and other forms of life) and physical components (soil, water, air, climate, and topography) which interact together. In terms of “Urban Green infrastructure (UGI)”, these components are in a combination of natural and constructed materials of urban space that have an important role in metabolic processes, biodiversity, and ecosystem resiliency underlying valuable ecosystem services. The increase in the world’s population in urban areas is a driving force to threat the environmental resources and public health in cities; thus, the necessity to adopt sustainable practices for communities are crucial for improving and maintaining urban environmental health. This chapter emphasizes the most important issues associated with urban ecosystem, highlighting the recent findings as a guide for future UGI management, which can support city planners, public health officials, and architectural designers to quantify cities more responsive, safer places for people.

Cooling Effects

Urban ecosystem services (ES) contribute to the compensation of negative effects caused by cities by means of, for example, reducing air pollution and providing cooling effects during the summer time. In this study, an approach is described that combines the regional biotope and land use data set, hemeroby and the accessibility of open space in order to assess the provision of urban ES. Hemeroby expresses the degree of naturalness of land use types and, therefore, provides a differentiated assessment of urban ES. Assessment of the local capacity to provide urban ES was conducted with a spatially explicit modeling approach in the city of Halle (Saale) in Germany. The following urban ES were assessed: (a) global climate regulation, (b) local climate regulation, (c) air pollution control, (d) water cycle regulation, (e) food production, (f) nature experience and (g) leisure activities. We identified areas with high and low capacity of ES in the urban context. For instance, the central parts of Halle had very low or no capacity to provide ES due to highly compact building styles and soil sealing. In contrast, peri-urban areas had particularly high capacities. The potential provision of regulating services was spatially limited due to the location of land use types that provide these services.

Future Work

Humans rely upon ecosystem services to regulate their environment and to provide resources and cultural benefits. As the world’s urban population grows, it becomes increasingly important to find ways of improving the provision of ecosystem services in urban areas. However, the kinds of ecosystem services that are most needed or demanded by urban populations, and the opportunities to provide these, vary widely in cities around the world. Here we explore variation in climate, Human Development Index (HDI), and population density, and discuss their implications for providing and managing urban ecosystem services. Using 221 published studies of urban ecosystem services, we analyse the extent to which existing research adequately covers global variation in climatic and social conditions. Our results reveal an under-representation of studies from tropical cities and from lower HDI countries, with implications for how we conceptualize and quantify urban ecosystem services, and how we transfer benefits across case studies. Future work should be aimed at correcting these deficits and determining the extent to which conclusions about urban ecosystem services are transferable from one city to another.

Abstract In building a sustainable society, numerous ecosystem services have shown to play important roles for the benefit of urban residents. The distinct concept of Urban Ecosystem Services (UES) to accentuate and enhance the value of urban ecosystems has been proposed, primarily in research, with implementation in practice still at an early stage. This study examined challenges to future implementation of the UES concept in municipal planning and management of urban green spaces. Based on interviews in six Swedish municipalities, we identified four overall discourses challenging implementation of UES in municipal practice. These included (i) a need to prioritize UES in municipal planning in order to address the contemporary challenges of e.g., urbanization and biodiversity loss. This in turn creates (ii) a need for increased holistic thinking within the municipal organization, based on (iii) further documentation and standards, which should help (iv) initiate organizational transition and cross-sectorial approaches. These discourses provide interrelated challenges that could also act as opportunities for scientists and practitioners collaborations to advance integration of UES into planning and management, thereby increasing the sustainability of urban environments. This work provides a starting point for introduction of the UES concept into municipal planning.

AbstractEcosystem services are an important, but often invisible component of the urban landscape. Humans have altered the environment in cities, leading to degraded or missing ecosystem services in many cases. To enhance or replace these services, many urban municipalities are integrating green spaces and infrastructure into urban planning. We have designed an activity to help undergraduate students: 1) recognize the importance of urban ecosystem services, 2) identify when they are degraded or missing, and 3) integrate “green” ideas from multiple sources to propose improvements to them. To help students achieve these goals, we asked them to evaluate an underutilized space on their own campus, and propose a redesign of that space to support ecosystem services. While many students struggled initially to link urban ecosystem services with specific proposed improvements, we found that having students work together in groups for a second redesign often improved understanding and also resulted in more creative and interdisciplinary designs. The exercise also helped students to better identify ecosystem services and allowed them to practice integrating multiple viewpoints while proposing solutions to local environmental problems.

Urban Green Spaces

In the context of urban land-use growth and the consequent impacts on the environment, green spaces provide ecosystem services for human health. The ecosystem services concept synthesises human–environmental interactions through a series of combined components of biodiversity and abiotic elements, linking ecological processes and functions. The concept of green infrastructure (GI) in the urban context emphasises the quality and quantity of urban and peri-urban green spaces and natural areas. In dense urban contexts, the applications of GI are limited and not applied to the potential urban spaces such as roofs and gardens. Often, roofs are characterised by impermeable paved surfaces with negative effects on human well-being, whereas garden designs do not consider social needs and environmental interactions. The role of urban stressors or the urban context as a driving force or pressure of urban green space is not always well understood and employed in the planning of green spaces. This is partly due to a knowledge gap between different science disciplines that operate on different scales, from single processes of the plants (which focus on plant responses to environmental stresses affecting human well-being) to urban ecosystems (which focus on the biodiversity and urban space planning–human well-being relationship). This can create a paradox, as green spaces that are not adequately designed might not produce the expected effects. In this paper, an overview of benefits and limitations of applying the ecosystem services approach when designing green spaces is presented. The focus is on the main urban ecosystem services provided by green roofs and community gardens such as GI that can represent strategies to provide ecological and social multifunctionality to waterproofed surfaces connected to the buildings and low-exploited gardens being the main areas that affect dense urban settlements, and thus, increasing the ecosystem services in the urban environment, such as reducing the Urban Heat Island, as well as flooding events. Specifically, the paper highlights (i) feedback between ecological processes and functions that support ecosystem services, (ii) urban environmental stresses in relation to disservices that these can create for human well-being and (iii) key issues that should be considered in the planning and design of urban ecosystem services. Such a new vision of urban ecosystem services highlights the need to look at GI as an active part of the urban space design in the built environment.
