ABSTRACT This study examines attitudes toward urban green space among homeowners in the River Rouge Watershed of southeast Michigan. Trees play a significant role in urban areas by providing numerous environmental, economic and social benefits to community residents. But public attitudes toward trees are not well understood. Through survey research we found that residents are most likely to value trees for personal benefit (like shade) but that social reasons are also valuable (improving the neighborhood). We also illustrate that cost is not an impeding factor in willingness to plant trees. Finally, our study reveals that homeowners felt tree planting is both an individual responsibility as well as a government responsibility. On the basis of these findings, we recommend that urban forestry policy should focus on education and outreach in an attempt to marry tree-planting initiatives to the individual benefits of trees as well as the community benefits of urban green space.

Urban green spaces can provide many types of ecosystem services for residents. An imbalance in the pattern of green spaces leads to an inequality of the benefits of such spaces. Given the current situation of environmental problems and the basic geographical conditions of Xi’an City, this study evaluated and mapped four kinds of ecosystem services from the perspective of equity: biodiversity, carbon sequestration, air purification, and climate regulation. Regionalization with dynamically constrained agglomerative clustering and partitioning (REDCAP) was used to obtain the partition groups of ecosystem services. The results indicate that first, the complexity of the urban green space community is low, and the level of biodiversity needs to be improved. The dry deposition flux of particulate matter (PM2.5) decreases from north to south, and green spaces enhance the adsorption of PM2.5. Carbon sequestration in the south and east is higher than that in the north and west, respectively. The average surface temperature in green spaces is lower than that in other urban areas. Second, urban green space resources in the study area are unevenly distributed. Therefore, ecosystem services in different areas are inequitable. Finally, based on the regionalization of integrated ecosystem services, an ecosystem services cluster was developed. This included 913 grid spaces, 12 partitions, and 5 clusters, which can provide a reference for distinct levels of ecosystem services management. This can assist urban managers who can use these indicators of ecosystem service levels for planning and guiding the overall development pattern of green spaces. The benefits would be a maximization of the ecological functions of green spaces, an improvement of the sustainable development of the city, and an improvement of people’s well-being.

Study Results

This paper presents the analysis of the effect of urban green space types on land surface temperature in Hue city. Data are collected with temperature monitoring results from each green space type and the interpretation of surface temperature based on Landsat 8 satellite image data to determine temperatures at different times of the year. Results showed that there was a significant correlation between types of urban green space and the surface temperature. Types of green space with a large area and vegetation indexes have a greater effect on temperature than areas with a smaller green space do. Green space types including forest green space, dedicated green space and agriculture green space have the most effect on the surface temperature. The forest area has the greatest influence on the temperature with a temperature difference of more than 1.6 degrees Celsius at 9:00 in the daytime. Besides, the results extracted from satellite images also show that the area of urban green space going to be reduced makes a contribution to increase the surface temperature of urban areas. The study results have established foundation for planning the green spaces in climate change challenges in Hue City.

Urban green space (UGS) plays a pivotal role in improving urban ecosystem services and building a livable environment for urban dwellers. However, remotely sensed investigation of UGS at city scale is facing a challenge due to the pixels’ mosaics of buildings, squares, roads and green spaces in cities. Here we developed a new algorithm to unmix the fraction of UGS derived from Landsat TM/ETM/8 OLI using a big-data platform. The spatiotemporal patterns and dynamics of UGSs were examined for 70 major cities in China between 2000 and 2018. The results showed that the total area of UGS in these cities grew from 2780.66 km2 in 2000 to 6764.75 km2 in 2018, which more than doubled its area. As a result, the UGS area per inhabitant rose from 15.01 m2 in 2000 to 18.09 m2 in 2018. However, an uneven layout of UGS occurred among the coastal, western, northeastern and central zones. For example, the UGS percentage in newly expanded urban areas in the coastal zone rose significantly in 2000–2018, with an increase of 2.51%, compared to the decline in UGS in cities in the western zone. Therefore, the effective strategies we have developed should be adopted to show disparities and promote green infrastructure capacity building in those cities with less green space, especially in western China.

Abstract. Many urban areas are facing challenges in balancing domestic and industrial water demands while simultaneously maintaining the water supply for green infrastructure. Consequently, quantitative knowledge about ecohydrological partitioning in different types of urban green space is crucial for balancing sustainable water needs in cities during future challenges of increasing urbanization and climate warming. Using isotopic tracers in precipitation and soil water, along with conventional hydrometric measurements in a plot-scale study in Berlin, Germany, we investigated water partitioning under different generic types of urban vegetation (grassland, shrub and trees). This allowed assessment of effects on subsequent evapotranspiration, subsurface flow paths and storage during a prolonged drought period with episodic rainfall. Water losses under forest were slightly higher than grassland over the monitoring in the growing season of 2019. Despite higher soil evaporation losses under urban grassland, higher interception and transpiration likely contributed to slower turnover of soil water and older groundwater recharge under urban trees. Shrub vegetation seemed to be most resilient to prolonged drought periods, with lower evapotranspiration losses. Our results contribute to a better understanding of ecohydrological partitioning under mixed urban vegetation communities and an evidence base for better adaptive management of urban water and irrigation strategies to sustainably meet the water demands of urban green spaces.

Urban Water Cycle

Increased impervious surfaces due to urbanization have reduced evaporation and infiltration into the soil compared with existing natural water cycle systems, which causes various problems, such as urban floods, landslides, and deterioration of water quality. To effectively solve the urban water cycle issue, green infrastructure using urban green space has emerged to reduce runoff and increase evaporation. It has the advantage of restoring the water cycle system of urban areas by complementing the failure of conventional stormwater treatment systems. However, urban areas under high-density development have limited green space for stormwater treatment. Hence, it is necessary to efficiently utilize street trees and small green spaces to improve the urban water cycle through green space. In this study, we simulated different green space distribution scenarios in the virtual domain to find the optimal strategy of green space planning. Compared to clustered scenarios, dispersed green space distribution scenarios and placing green space downstream were more effective in reducing the runoff amount. The paper provides insights into the considerations for determining green space spatial plan and zoning regulations for stormwater treatment by green infrastructure.

The Impact

Urbanization continues to trigger massive land-use land-cover change that transforms natural green environments to impermeable paved surfaces. Fast-growing cities in Asia experience increased urban temperature indicating the development of urban heat islands (UHIs) because of decreased urban green space, particularly in recent decades. This paper investigates the existence of UHIs and the impact of green areas to mitigate the impacts of UHIs in Colombo, Sri Lanka, using UrbClim, a boundary climate model that runs two classes of simulations, namely urbanization impact simulations, and greening simulations. The urbanization impact simulation results show that UHIs spread spatially with the reduction of vegetation cover, and increases the average UHI intensity. The greening simulations show that increasing green space up to 30% in urban areas can decrease the average air temperature by 0.1 °C. On the other hand, converting entire green areas into urban areas in suburban areas increases the average temperature from 27.75 °C to 27.78 °C in Colombo. This demonstrates the sensitivity of UHI to vegetation cover in both urban and suburban areas. These seemingly small changes are average grid values and may indicate much higher impacts at sub-grid levels.

Green City

World urban areas are increasingly dabbling with the triple challenge of pollution, congestion and environmental degradation. The quest for sanity and healthy urban living led to the introduction of urban green space initiatives. Green space has become primordial in urban areas as it enhances public health, recreation, amenities and property values through its location, accessibility, proximity and serviceability. In a bid to develop an urban green space in Bamenda, the City Council identified the Bamenda escarpment in 2011 for protection. This was followed by a Green City Initiative now captioned the Green City Project. The Bamenda City Council partnering with the UN-Habitat and the Dordrecht/Gorinchem City Councils of the Netherlands seeks to implement an urban greening project with major focus to map out potential areas for creating parks in Bamenda. This project which is a novelty in the rapidly changing urban landscape of Cameroon seeks to contribute to building a green economy that enhances nature, environmental protection and at the same time offers economic and social benefits to its citizens. In this study, we examine the opportunities and challenges of urban greening in Bamenda. Some 50 inhabitants around the escarpment were purposively sampled while council authorities and other stakeholders were interviewed in the Bamenda I municipality in order to assess the opportunities, challenges and prospects for the project. This was complemented by secondary data obtained from the Bamenda City Council. The conclusion drawn is that the initiative will provide opportunities for employment, generate revenue for the City Council and prevent uncontrolled city sprawl against the backdrop of the relatively unstable nature of the foothills (due to mass wasting processes) and land use competition, largely driven by population growth and the daunting task of relocating prior users. We therefore argue in favour of the effective application of urban development policies to restrict encroachment around the area and to engage in slope stabilization where necessary.

Background and Objectives: Cultural ecosystem services of urban green spaces are increasingly important and often recognized as such by people living in urban areas. Qualitative studies on perception of cultural ecosystem services from urban green spaces are still rare. Previous studies addressed only certain types of urban green space and often only some services. There is a lack of understanding how people perceive cultural ecosystem services from different types of tree-based urban green spaces. Hence, the purpose of the study was to explore whether and how people perceive and use cultural ecosystem services of different types of tree-based urban green spaces. Materials and Methods: Focus groups were conducted with citizens in each city district. Interviews were recorded, transcribed and transcripts analyzed in MAXQDA software. We used bottom up code-category-theme approach to analyze the data without predefined set of codes or categories. Results: Place attachment, aesthetic and recreational services were more recognized than educational and cultural identity services. For place attachment, most important single attributes were positive memories, and good maintenance, while most important categories were facilities, existence of emotional ties, possibility of experiences, recreational use and access. Presence of specific tree species and presence of trees in general were most important attributes for aesthetic services, while possibility of experiences and trees were the most important categories. Conclusions: People perceived various cultural ecosystem services from tree-based urban green space, even though some services more than others. Recreation may be the underlying goal of our participants when interacting with tree-based urban nature. Forests, parks were recognized as those providing multiple cultural ecosystem services. However, other types of green spaces were also recognized as bearers of these services, albeit with less services and attributes attached. It supports the importance of careful planning of urban green spaces in terms of providing a variety of green space types. The study provides basis for later quantification of cultural ecosystem services (CES) from tree-based urban green space.

AbstractUrban green spaces provide ecosystem services that can be used by the local population. The valuation of these ecosystem services in urban areas gives information for stakeholders and decision-makers to improve urban planning processes. In addition, this information can be used to provide a better understanding of how urban green spaces should be managed. In this study, we quantify and monetize four ecosystem services (carbon sequestration and storage, air pollution removal, runoff reduction, groundwater recharge) provided by the urban green space of Schlosspark Nymphenburg in Munich, Germany. We classify four different land cover types (tree, grass/herbaceous, water, impervious) to calculate different amounts of ecosystem services according to the land cover type. In addition, we quantify the maintenance costs which this urban green space causes to the city of Munich. The interpretation, communication and risks of valuations studies are discussed.

Urban forestry and green spaces have less priority in urban planning. This research intends to assess the policy and planning of urban green spaces with their potential implementation status and challenges in planning and implementation. The general objective is to assess urban green space planning, policy, and implementation strategies and challenges encountered in Addis Ababa. The primary data was collected through key informant interviews, focus group discussions, and field observation; secondary data from a literature review along with examining policy and masterplans of Addis Ababa has been used. The mapping of stakeholder and institutional arrangements is analyzed using stakeholders’ consultation. Triangulation is used for data validation and analysis. Existing policy and proclamations must be supported by legislative regulations and implementation frameworks that provide the basis for concrete action plans. The incentives stipulated by the forest policy are not implemented to the required level. The 10th masterplan of the city (2017–2027) shows that the city will increase its green area development and public recreation coverage to 30% by 2020. Principles, such as multi-functionality, connectivity, green-grey interaction, and social inclusiveness, are considered in the planning of the green space development in the 10th masterplan. The research concludes that regulations and directives are not clearly drafted by responsible bodies, and low enforcement is hardly applied with respect to the green space development of Addis Ababa.
