Studying green urban infrastructure is important because of its ecosystem services, contributing to the welfare and comfort of citizens, mitigation of climate changes, and sustainability goals. Urban planning can increase or diminish the performance of ecosystem services. Despite numerous studies on the green infrastructure–services–planning nexus, there are very few concrete planning recommendations. This study aims to provide such recommendations for a broader audience by analyzing the dynamic of open green areas in Polish and Romanian cities, connected with its drivers. A novel approach including mathematical modeling and geostatistical analyses was applied to Urban Atlas and statistical yearbooks data. The results indicated that open green areas were lost and fragmented in all Romanian and Polish cities during 2006–2018. The drivers included urban built-up areas, population and density, the number of building permits, number of new dwellings completed, number of employees, and total length of roads. The study also revealed a tremendous lack of consistent datasets across the countries using the same statistical indicators. Based on the findings, planners should aim to preserve and develop urban greenery and maintain its continuity. City managers should use more research and decision-making policy developers to develop targeted policies and scientists should develop planning manuals.

As cities increase in size and density, the ecosystem services supplied by urban greenery and green infrastructure are increasingly vital for sustainable, liveable urban areas. However, retaining and maximising urban greenery in densifying cities is challenging. Governments have critical roles in addressing these challenges through policy development and implementation. While there has been significant attention on the quality and quantity of green space on public land, there is an increasing focus on policy mechanisms for integrating green infrastructure into the private realm, including green roofs, walls, facades, balconies and gardens. As part of City of Melbourne’s efforts to increase greening across the municipality, its 2017 Green Our City Strategic Action Plan includes specific focus on the private realm, and development of regulatory processes for green infrastructure. This article reports on a participatory research project to develop a Green Factor Tool for application to building development proposals in Melbourne. We focus on the transdisciplinary collaborations that brought together contributions from researchers, practitioners, policymakers and designers. We discuss how local research on green space contributions to provision of ecosystem services shaped the design of the tool and provided the tool’s rigorous evidence-base. Finally, we consider the roles of urban planning in retaining and maximising urban green spaces in densifying urban areas.

Green areas in cities and their ecosystem services (ES) offer residents various benefits. The range of services depends on biodiversity of a green space. The aim was to determine the relationship between biodiversity in different categories of green areas in the city and the ecosystem services, which appear in it. We made 108 relevés in the autumn and spring time, within nine categories of green areas in the Municipality of Ljubljana. In each category the range of ES was assessed based on field analysis and compared with literature assessed ecosystem services. Results showed that the category of forests differ from others. Other categories were similar to each other, in particular grassland categories. Also, a positive relationship linkage was found - more plant species mean more assessed ecosystem services in a specific green infrastructure category.

The continuous presence of the landscape concept in planning and design of the Banja Luka area until the end of the 20th century influenced the formation of the identity of Banja Luka as a green city. However, in the last twenty years, there is an absence of the green city concept from planning and designing of Banja Luka's area. In order to improve the state of urban greenery and achieve the satisfactory condition of the endangered landscape elements, this paper re-examines their significance for the city. The green infrastructure has ecological, social and aesthetic functions and it becomes an imperative in defining the strategic goals of a sustainable city. The study showed, that there are possibilities of increasing the size of green areas and improving the quality of green areas in the built city tissue. One of those possibilities is transformation of the existing brownfields into green areas. From the perspective of urban planning, the purpose of this paper is to point out the possibility of implementing the greenways in the city structure for the case study in Banja Luka. In this context, the research focuses on the area of the former Incel factory and the ability to transform the abandoned railways into a greenway. In this research, the sustainable spatial development context of Banja Luka is regarded as a permanent category which includes, among the others, the ambient values, the spirit of the place and the features of a green city are important for the city's inhabitants.

Strategic environmental assessment (SEA) can support decision-makers in constructing more sustainable plans, programs, and policies (PPPs). To be more coherent with new frontiers of sustainable cities, PPPs need to include conservation objectives and to increase ecosystem service (ES) strategies. The ES concept is not intrinsic to the SEA process; therefore, it is necessary to develop an approach and methodology to include it. In this paper, we propose a methodology to integrate the concept of ecosystem services in all phases of the SEA process for a sub-urban plan, including the design of mitigation measures. The case study is represented by a peri-urban development plan in the municipality of Gallipoli in South Italy, characterized by a strong tourism economy and valuable agro-ecosystems. The analysis shows the priority ecosystem services that are selected considering the sustainable development and environmental goals, the context of referment, and the aims of the peri-urban plan. After, we highlight the potential ecosystem services developed considering the design of mitigation actions like green infrastructure, which could be implemented in the peri-urban plan. The capacity to develop green infrastructure in SEA processes can configure the SEA as a tool for ecological urban design that is integrated with urban planning. This requires the ability to transfer ecological and planning theories into practical actions and the capacity of different disciplines to work in a transdisciplinary approach.

The quality of life in our cities critically depends on the intelligent planning and shaping of urban living space, in particular urban nature. By providing a wide range of ecosystem services (ES), urban nature essentially contributes to the well-being of city dwellers and plays a major role in avoiding common diseases through its positive impact on physical and mental health. Health is one of the most important factors underlying human welfare and is, thus, vital to sustainable development. The ES of urban green space provide other social-cultural functions alongside public health, for example by fostering environmental justice and citizenship participation. Thus, they should always be considered when searching for solutions to urban problems. The aim of this research was to determine the impact of green areas in three selected cities on the health and well-being of people by self-reporting of green areas’ visitors. To this end, we posed the research question: which types and characteristics of urban green space are most appreciated by city dwellers? Based on our findings, we have drawn up recommendations for practices to promote better living conditions. We have also pinpointed obstacles to and opportunities for leisure time activities as well as ways of supporting the public health of citizens.

Constructed wetlands (CWs) are nature-based solutions (NBS) for water pollution control that can also be designed to be multipurpose in terms of additional ecosystem services (ESs), such as biodiversity support and social benefits. Awareness about additional ESs of CWs can be raised with value transfer (VT) methods for ESs monetization, in particular, the simplified adjusted unit VT method. A multi-criteria analysis (MCA) was performed to compare grey and green infrastructure alternatives for the management of a combined sewer overflow in the Buccinasco town (Italy), in which the criteria related to ESs were monetized with an adjusted VT method (B£ST software). The results highlighted the potential interest in the implementation of the green infrastructure in a new urban park, due to the activation of additional ESs of interest, such as health and recreational aspects. The results were also confirmed by a sensitivity analysis, which simulated the variation of preferences among different stakeholder groups (e.g., citizens, environmentalists). In conclusion, this work provided a transparent methodology to support decisions regarding green and grey infrastructure, allowing to evaluate additional ESs from the beginning of the decision stage with low cost and efforts.

More communities around the world are recognizing the benefits of green infrastructure (GI) and are planting millions of trees to improve air quality and overall well-being in cities. However, there is a need for accurate tools that can measure and value these benefits whilst also informing the community and city managers. In recent years, several online tools have been developed to assess ecosystem services. However, the reliability of such tools depends on the incorporation of local or regional data and site-specific inputs. In this communication, we have reviewed two of the freely available tools (i.e., i-Tree Canopy and the United Kingdom Office for National Statistics) using Bristol City Centre as an example. We have also discussed strengths and weaknesses for their use and, as tree planting strategy tools, explored further developments of such tools in a European context. Results show that both tools can easily calculate ecosystem services such as air pollutant removal and monetary values and at the same time be used to support GI strategies in compact cities. These tools, however, can only be partially utilized for tree planting design as they do not consider soil and root space, nor do they include drawing and painting futures. Our evaluation also highlights major gaps in the current tools, suggesting areas where more research is needed.

<p>Urban green infrastructure has various benefits known as ecosystem services such as regulating, cultural, provisioning and supporting services. Among the provided benefits there are decrease of air temperature, increasing humidity and mitigating urban heat island as regulating services; human-nature relations as cultural services; improving air quality, carbon sequestration as provisioning services and photosynthesis, nutrient and water cycling as supporting services. The high intensity of the urbanization process across the last decades coupled with weak legislative frameworks resulted both in large areas affected by urban sprawl and densification of the existing urban fabric. Both phenomenon generated loss in open spaces, especially green areas. In the context of the sustainable urbanization promoted by HABITAT Agenda, the knowledge related with the distribution, size and quality of urban green areas represents a priority. The study aim is to identify small urban green areas at local level at different time moments for a dynamic evaluation. We focused on small urban green areas since they are scarcely analysed even if their importance for the urban quality of life Is continuously increasing given the urbanization process. We used satellite imagery acquired by Planet Satellite Constellations, with a spatial resolution of 3.7 m and daily coverage, for extracting green areas. The images were processed using Geographic Object-Based Image Analysis (OBIA) techniques implemented in Esri ArcGIS Pro. The spatial analysis we performed generated information about distribution, surfaces, quality (based on NDVI) and dynamic of small urban green areas. The results are connected with the local level development of the urban areas we analysed, but also with the population consumption pattern for leisure services, housing, transport or other public utilities. The analysis can represent a complementary method for extracting green areas at urban level and can support the data collection for calculating urban sustainability indicators.</p>
