Collective management of urban green space is being acknowledged and promoted. The need to understand productivity and potential trade-offs between co-occurring ecosystem services arising from collectively managed pockets of green space is pivotal to the design and promotion of both productive urban areas and effective stakeholder participation in their management. Quantitative assessments of ecosystem service production were obtained from detailed site surveys at ten examples of collectively managed urban gardens in Greater Manchester, UK. Correlation analyses demonstrated high levels of synergy between ecological (biodiversity) and social (learning and well-being) benefits related to such spaces. Trade-offs were highly mediated by site size and design, resulting in a tension between increasing site area and the co-management of ecosystem services. By highlighting synergies, trade-offs and the significance of site area, the results offer insight into the spatially sensitive nature of ecosystem services arising from multi-functional collectively managed urban gardens.

Context. Primates are one of the most charismatic and widely studied vertebrate groups. However, the study of new world primates in green patches within urban areas has been neglected. Such primates have been viewed as a source of human–animal conflict; however, their ecological importance to urban ecosystems and their role in human well being is poorly understood. Aims. To increase understanding of both ecological and socioeconomical factors affecting the distribution, density and group sizes of urban marmosets in a large Brazilian city (Belo Horizonte). Methods. A map of vegetation cover and land use was produced and employed to investigate the distribution of marmosets. An online questionnaire was extensively publicised, which permitted the public to report the occurrence or not of marmosets near their residences. For sites with low salary levels and low internet availability, face-to-face interviews were conducted. Additionally, field surveys were conducted in 120 green areas identified by spatial analysis as potential areas of occurrence. The human population density, salary levels and green areas were posteriorly correlated with marmoset distribution. Key results. Despite the urbanisation and high human population density, green fragments within the city still housed marmoset groups. However, the presence of green areas did not always indicate primate presence. Group presence was significantly related to the size of parks or green areas and negatively related to built-up areas, and human density. Salary levels were related to more forested streets and possibly tolerance. Marmosets were classified as urban utilisers. Conclusions. The human–wildlife conflict with marmoset species was relatively low, owing to marmoset avoidance of built-up areas. The interaction of marmoset species and city dwellers was mainly limited to borders of forest fragments and inside city parks, and appeared to be human motivated. Implications. This study showed the importance of public involvement in wildlife studies in urban environments; clarifying the interaction between city dwellers and wild species is essential to mitigate negative interactions.

Studies have repeatedly affirmed the positive links between human and environmental health but few have sufficiently addressed the complexity brought about by the range of urbanity, population and both green space and domestic gardens cover associated human settlements. With the global population increasingly residing in cities, the relevance of urbanisation, local population and discrete types of green space provision on measures of health, remains a research imperative. To explore this complexity, a series of regression models were employed to quantify the mitigation of local health deprivation by green space and domestic gardens, across a four-stage rural-urban gradient, controlling for household income and local population. The population-standardised quantification of green space provision offered greater interpretive power than did a simple measure of land cover density. Domestic gardens, of the two green land-cover types, provided the most convincing mitigating effect on health deprivation. The findings call for increased acknowledgement of urban gardens in local health promotion, and a closer consideration of local population in planning green space provision and management.

Within the ecosystem services framework, valuations of natural capital have primarily taken a landscape-scale approach. The generation of transferable monetary values for individual ecosystems has likewise depended on assessments carried out at large spatial scales. Such methods, however, lack adequate regard for the complex natural habitats. This complexity is heightened in urban areas where green spaces provide multiple services according to use and participation. Hence, there is a need to acknowledge the unique value of urban nature, and the socially-mediated nature of its productivity. This need was addressed through a study of collectively managed green spaces in a northwest England conurbation (UK). Ninety-one sites were identified, followed by a case study of twelve sites assessing their value across four ecosystem services. A subsequent projection of the value of stakeholder-led land management was calculated and compared to an existing reference for the value of urban green space from The Economics of Ecosystems and Biodiversity database. The study found that collectively managed sites contribute considerable added-value to urban natural capital. In addition, the work highlights the shortcomings of applying transferable values to multi-functional habitat types, calling for a closer consideration of social-ecological contexts in the valuation of ecosystem services.

Novel approaches to natural resource management, particularly those which promote stakeholder participation, have been put forward as fundamental ingredients for establishing resilient, polycentric forms of environmental governance. This is nowhere more pertinent than in the case of the complex adaptive systems associated with urban areas. Decentralisation of urban green space management has been posited as an element thereof which, according to resilience thinking, should contribute to the adaptive capacity of cities and the ecosystem services upon which they rely. Implicit in this move towards increased adaptive capacity is the ability to manage through innovation. Although the importance of innovation towards system adaptability has been acknowledged, little work has thus far been carried out which demonstrates that innovative use of urban green space represents a form of adaptive response to environmental conditions. The current paper reports on research which maps examples of organised social-ecological innovation (OSEI) in an urban study area and evaluates them as adaptive responses to local environmental conditions which may contribute to system resilience. The results present OSEI as a coherent body of responses to local social and environmental deprivation, exhibiting diversity and adaptability according to individual contexts. The study therefore provides evidence for the importance of local stakeholder-led innovation as in the building of adaptive capacity in urban social-ecological systems.

Polycentric governance and stakeholder participation in natural resource management have potential benefits for both human and environmental well-being. Researchers and decision-makers have attempted to conceptualise the ecological, social and political potential of such semi-formal approaches to urban green space management. However, few studies have quantified the actual benefits in terms of biodiversity and associated ecosystem service provision, or the factors that mediate levels of participation.The links between biodiversity potential, site access and user participation were explored in a case study comprising ten established examples of organised social–ecological initiatives in the inner-city area of Greater Manchester. At the micro-scale, the case study quantified the levels of community involvement(measured in volunteer hours month−1) in local green commons and the biodiversity potential (assessed using floristic and structural diversity as a surrogate) of the ten sites. Descriptive analysis identified that site spatial and design characteristics affected all three measures and subsequent correlational analyses revealed a high degree of synergy between site use and biodiversity.The study thereby provides quantitative evidence of the synergistic relationship between green space use and urban biodiversity and, importantly, the positive feedbacks which should result between volunteer input and the local generation of ecosystem services. The study provides support for the promotion of a highly decentralised, stakeholder-led stewardship of green space as a valid consideration in the management of urban ecosystem services.

Pockets of green space in cities can provide important ecosystem services for urban residents. As naturalistic spaces in urban areas become increasingly sparse, communities are beginning to co-manage existing incidental pockets of land towards the creation of communal natural resources. Such green commons can be productive in terms of ecosystem services through targeted management such as in the case of urban agriculture. Although some work has been done to explore the motives behind and potential benefits of informal green space management, further research is required to understand those characteristics of site management and community input which contribute to the enhancement of site-specific ecosystem service production. A case study of ten examples of community-managed green space was undertaken to evaluate the contributory factors relating to site character and management which influenced productivity as defined by the cumulative provision of four urban-relevant ecosystem services. The analysis revealed that the level of community involvement, measured as intensity of volunteer hours, was highly instrumental in the productivity of sites. Food production also proved to be catalytic for the enhancement of ecosystem services whereas extent of vegetative cover and increasing site size were, counter-intuitively, detrimental to overall site productivity. The study therefore supports the promotion of participatory approaches to the management of ecosystems services in urban areas, particularly those which take small-scale urban agriculture as a primary practice.

Urbanization is one phenomena that drives land use pattern change. Persistent rapid urbanization is associated with depletion of natural resources and worsening conditions in the urban environment. Monitoring urban development is, therefore, an absolute necessity in order to assure sustainable cities in the future. The main objective of this paper is to develop and apply an urban growth potential model incorporating spatial metrics. The model has been tested in Jinan City, China. Firstly, two satellite images (1989 and 2004 SPOT) were used to extract the land-cover. A general land use spatial pattern analysis, based on landscape metrics and a transformation matrix analysis, was conducted. Secondly, a moving window method was used to identify and capture the urbanization process through the PLAND landscape metric. The remote satellite data have been further processed: first to produce an initial state of the land-cover surface, and second to perform a time-series analysis and to asse...

ABSTRACT Urban green spaces provide cooler microclimates and create localized urban cool islands and, as part of an adaption strategy to cope with future urban climate change, have been proposed as a means to mitigate the urban heat island effect. Numerous previous research papers have discussed green-space size, type, and vegetation density, as well as many other factors that might influence green-space cooling effects. However, little has been done with regard to exploring and quantifying the characteristics of the green-space cool island (UCI). It is also largely unknown whether or how the patterns of green space and land use, as well as the adjacent urban thermal environment, affect UCIs. In this paper, based on the satellite image, the land surface temperature (LST) was retrieved and the UCI was first identified, then the UCI intensity, one of the UCI characteristics, is defined and at last multiple linear regression models used to explore and quantify the combined effects of factors related to UCI intensity. The results show that the intensity differed between UCIs, and that it was correlated significantly with the extent of and mean temperature reduction associated with a UCI. Multiple linear regression analysis shows that UCI intensity was affected by areas of forest vegetation and its spatial arrangements, as well as by the composition of the cool island and its neighboring thermal environment. The study validated the suitability of using intensity as an indicator of the UCI. Identifying the UCI as a result of the green-space cooling effect, will help in the management and planning of the spatial arrangement of green spaces in cities to mitigate the effects of the urban heat environment and help cities adapt to the climate change.

The landscape of urban areas is unique, dissimilar to all other landscapes studied by ecologists: it
appears to be dominated by residential and commercial buildings, paved surfaces, roads, railways
and so on. However, urban landscapes are crammed with life: ecosystems, biodiversity, and, of
course, people. Urban environments are a dense mix of many different types of structures (organic,
inert, and man-made; natural and modified). And these landscapes are growing, becoming ever more
pervasive across the globe. Anthropogenic and ecological processes: life processes, interactions and
adaptations; movement of materials and energy through living communities; successional
development of ecosystems; and dynamic changes in abundance and distribution of organisms and
biodiversity in the context of the environment, occur, perhaps more so in urban environments than
elsewhere. These processes are modified in identifiable ways within the urban landscape.
The convenors of this symposium will illustrate these processes and their modifications through
examples drawn from their own academic and professional practice, they will present an overview of
the contributions made within the symposium and they will raise questions about the future agenda for
research into urban ecology. In particular they will focus on the ecosystem approach and how that is
being operationalized.

Europe is a highly urbanised continent. The consequent loss and degradation of urban and peri-urban green space could adversely affect ecosystems as well as human health and well-being. The aim of this paper is to formulate a conceptual framework of associations between urban green space, and ecosystem and human health. Through an interdisciplinary literature review the concepts of Green Infrastructure, ecosystem health, and human health and well-being are discussed. The possible contributions of urban and peri-urban green space systems, or Green Infrastructure, on both ecosystem and human health are critically reviewed. Finally, based on a synthesis of the literature a conceptual framework is presented. The proposed conceptual framework highlights many dynamic factors, and their complex interactions, affecting ecosystem health and human health in urban areas. This framework forms the context into which extant and new research can be placed. In this way it forms the basis for a new
interdisciplinary research agenda.
