- Greening cities, namely installing new parks, rooftop gardens or planting trees along the streets, undoubtedly contributes to an increase in wellbeing and enhances the attractiveness of open spaces in cities. At the same time, we observe an increasing use of greening strategies as ingredients of urban renewal, upgrading and urban revitalization as primarily market-driven endeavours targeting middle class and higher income groups sometimes at the expense of less privileged residents. This paper reflects on the current debate of the social effects of greening using selected examples. We discuss what tradeoffs between social and ecological developments in cities mean for the future debate on greening cities and a socially balanced and inclusive way of developing our cities for various groups of urban dwellers. We conclude that current and future functions and features of greening cities have to be discussed more critically including a greater awareness of social impacts.

- Remote sensing has evolved to become a key tool for various fields of environmental analysis, thus actively informing policy across areas and domains. To evaluate the degree to which remote sensing is contributing to the science of ecologically-oriented urban planning, we carried out a systematic literature review using the SCOPUS database, searching for articles integrating knowledge in urban planning, remote sensing and ecology. We reviewed 186 articles, analysing various issues in urban environments worldwide. Key findings include that the level of integration between the three disciplines is limited, with only 12% of the papers fully integrating ecology, remote sensing and planning while 24% of the studies use specific methods from one domain only. The vast majority of studies is oriented towards contributing to the knowledge base or monitoring the impacts of existing policies. Few studies are directly policy relevant by either contributing to direct issues in planning and making specific design suggestions or evaluations. The accessibility of the scientific findings remains limited, as the majority of journal articles are not open access and proprietary software and data are frequently used. To overcome these issues, we suggest three future avenues for science as well as three potential entry points for remote sensing into applied urban planning. By doing so, remote sensing data could become a vital tool actively contributing to policies, civil engagement and concrete planning measures by providing independent and cost effective environmental analyses.

- Understanding opportunities as well as constraints for people to benefit from and take care of urban nature is an important step toward more sustainable cities. In order to explore, engage, and enable strategies to improve urban quality of life, we combine a social-ecological-technological systems framework with a flexible methodological approach to urban studies. The framework focuses on context dependencies in the flow and distribution of ecosystem service benefits within cities. The shared conceptual system framework supports a clear positioning of individual cases and integration of multiple methods, while still allowing for flexibility for aligning with local circumstances and ensuring context-relevant knowledge. To illustrate this framework, we draw on insights from a set of exploratory case studies used to develop and test how the framework could guide research design and synthesis across multiple heterogeneous cases. Relying on transdisciplinary multi- and mixed methods research designs, our approach seeks to both enable within-case analyses and support and gradually build a cumulative understanding across cases and city contexts. Finally, we conclude by discussing key questions about green and blue infrastructure and its contributions to urban quality of life that the approach can help address, as well as remaining knowledge gaps both in our understanding of urban systems and of the methodological approaches we use to fill these gaps.

Enabling Green and Blue Infrastructure to Improve Contributions to Human Well-Being and Equity in Urban Systems

- The circumstances under which different ecosystem service benefits can be realized differ. The benefits tend to be coproduced and to be enabled by multiple interacting social, ecological, and technological factors, which is particularly evident in cities. As many cities are undergoing rapid change, these factors need to be better understood and accounted for, especially for those most in need of benefits. We propose a framework of three systemic filters that affect the flow of ecosystem service benefits: the interactions among green, blue, and built infrastructures; the regulatory power and governance of institutions; and people's individual and shared perceptions and values. We argue that more fully connecting green and blue infrastructure to its urban systems context and highlighting dynamic interactions among the three filters are key to understanding how and why ecosystem services have variable distribution, continuing inequities in who benefits, and the long-term resilience of the flows of benefits.

- Context Urban densification has been argued to increase the contrast between built up and open green space. This contrast may offer a starting point for assessing the extent and magnitude of the positive influences urban green infrastructure is expected to have on its surroundings.Objectives Drawing on insights from landscape ecology and urban geography, this exploratory study investigates how the combined properties of green and grey urban infrastructures determine the influence of urban green infrastructure on the overall quality of the urban landscape.Methods This article uses distance rise-or-decay functions to describe how receptive different land uses are to the influence of neighbouring green spaces, and does this based on integrated information on urban morphology, land surface temperature and habitat use by breeding birds.Results Our results show how green space has a non-linear and declining cooling influence on adjacent urban land uses, extending up to 300-400 m in densely built up areas and up to 500 m in low density areas. Further, we found a statistically significant declining impact of green space on bird species richness up to 500 m outside its boundaries.Conclusions Our focus on land use combinations and interrelations paves the way for a number of new joint landscape level assessments of direct and indirect accessibility to different ecosystem services. Our early results reinforce the challenging need to retain more green space in densely built up part of cities.

Scale and context dependence of ecosystem service providing units

- Ecosystem services (ES) have been broadly adopted as a conceptual framing for addressing human nature interactions and to illustrate the ways in which humans depend on ecosystems for sustained life and well-being. Additionally, ES are being increasingly included in urban planning and management as a way to create multi-functional landscapes able to meet the needs of expanding urban populations. However, while ES are generated and utilized within landscapes we still have limited understanding of the relationship between ES and spatial structure and dynamics. Here, we offer an expanded conceptualization of these relationships through the concept of service providing units (SPUs) as a way to plan and manage the structures and preconditions that are needed for, and in different ways influence, provisioning of ES. The SPU approach has two parts: the first deals with internal dimensions of the SPUs themselves, i.e, spatial and temporal scale and organizational level, and the second outlines how context and presence of external structures (e.g, built infrastructure or larger ecosystems) affect the performance of SPUs. In doing so, SPUs enable a more nuanced and comprehensive approach to managing and designing multi-functional landscapes and achieving multiple ES goals.

- Present and future urbanization together with climate change and other uncertainties make urban quality of life a criticalissue, and one that will need constant attention and deliberation. Across cities and contexts, urban ecosystems in the form of greenand blue infrastructure, have the potential to contribute to human well-being as well as supporting biodiversity, and to do so underdiverse conditions. However, the realization of this potential depends not only on the green and blue infrastructure itself, the well-beingbenefits are outcomes of the structures and processes of the entire urban system. Drawing on theory and insights from social-ecologicaltechnological systems (SETS) research and resilience assessments, we describe how a systemic understanding of the generation anddelivery of green and blue infrastructure benefits may inform cross-sectoral strategies and interventions for building resilience aroundthis particular aspect of human well-being. Connecting SETS to non-academic discourse and practice, we describe the urban systemin terms of three systemic controlling variables: infrastructure, institutions, and the perceptions of individual beneficiaries, which wecall filters, and how these can be used in different participatory processes to assess and build resilience around green and blueinfrastructure and its benefits.To ground the conceptual and theoretical framework in real world complexity and make it operational in practice we discuss three casestudies applying the framework in Barcelona, Halle, and Stockholm. All cases share the same general three-step process but theirindividual combinations of methods and adaptions of the filters framework are designed to fit with three necessarily unique collaborative,transdisciplinary processes. The cases are discussed in terms of outcomes and output, the ways they made use of the conceptualframework, and the challenges they faced. This exploratory work points to a new way of engaging with urban resilience—the strengthof the approach is that it is not limited to the identification of specific interventions or policy options, nor trying to prevent change;rather it focuses on how to move with change and build resilience through constant balancing of different types of SETS change. Ourstudy reinforces the growing understanding of how well-being benefits positioned as emergent outcomes of internal SETS interactionsoffers leverage for mainstreaming green and blue infrastructure throughout diverse governance processes and sectors.

Bokkapitel (refereegranskat)abstract
- Land use and land cover largely determine the ecosystem functions that can occur, where they occur, and the organisms that enable those. The composition and configuration patterns of land use and land cover will impact urban biodiversity; therefore how we recognize and understand those patterns is relevant towards planning to enhance biodiversity in urban ecosystems. This chapter addresses the past, present, and future of land use and land cover in urban areas by covering three main sections: The history of land use/land cover in urban areas, how biodiversity connects to land use/land cover under a landscape ecology framework, and how planning for sustainability and fulfilment of sustainable development goals can be done by addressing urban biodiversity at a landscape scale. Through concepts, examples, and tools, we expect readers to become immersed in the importance of land use/land cover configuration and composition for urban biodiversity and related ecological processes.
