A monitoring tool for the provision of accessible and attractive urban green spaces

Abstract The availability of accessible and attractive green spaces is an integral part of urban quality of life. This paper presents an integrated indicator designed for: (1) the monitoring of the urban green space provision against quantitative and qualitative targets; (2) the comparison between cities and city parts; (3) the assessment of the effects of future policy scenarios; (4) the indication of locations where action is required. The indicator development was guided by five principles: “citizen based”, “functional levels”, “preconditions for use”, “variety of qualities”, and “multiple use”. The parameters were derived from the available research on public preferences and use of green spaces. The indicator is made operational in a GIS-based working procedure starting from the residential places and based on a two-step approach: (1) The accessibility: which green spaces are within reach at different functional levels? (2) The attractiveness: which are the accessible green spaces’ qualities? The GIS-model was applied in four cities of Flanders (northern part of Belgium): Antwerp, Ghent, Aalst and Kortrijk. This article explains the underlying ideas and the construction of the monitoring tool and discusses the suitability as a touchstone for current and future policy as well as its possible guiding role in local planning situations.

Health Benefits of Nature Experience: Psychological, Social and Cultural Processes

In this chapter we consider how experiences of nature can affect human health and well-being. We first address the matter of ‘what has been’; that is, we sketch the development of theory and research concerned with health benefits of natural environments, from ancient times to the current situation. This shows the current research to be a recent expression of a number of long-running, intertwined, social and cultural processes. We then discuss ‘where we are now’; that is, we overview current theories and related research concerning processes through which nature experience might provide health benefits. These processes concern environmental preferences, psychological restoration, and learning and personal development. Finally, we consider ‘where we are going’; that is, we consider some additional directions for research and we identify some issues that research will have to address in the foreseeable future.

Involving People in Urban Forestry — A Discussion of Participatory Practices throughout Europe

Planning and acting on issues relating to people’s living environment have increasingly become a socially embedded practice, shifting from serving an abstract public interest to actively engaging the public. Central to this approach is a greater emphasis on the exchange of knowledge and the development of ideas through communication with relevant stakeholders, including users, residents and community groups. This trend towards greater communication in urban environmental or ‘green’ planning parallels the current success of various concepts such as collaborative planning, citizenship, social capital and participatory democracy. In addition, urban renewal strategies and environmental improvement schemes for creating livable cities, the establishment of Local Agenda 21, and the growing attention to the social dimensions of sustainable forest management, all provide a context to develop new interactions between society and forestry. Cities, towns and suburbs are increasingly rich in different types of green spaces. In addition to traditional public areas such as urban woodland and parks, many different types of areas and new kinds of ownership or comanagement arrangements are now evident. As outlined by Agate (1998), these include community wildlife gardens, children’s farms, school nature areas and community forests. This new diversity provides many opportunities for community involvement – including training and education, consultation and active participation – the realization of which will fully develop many of the ‘real’ benefits from the urban forest: health and well-being, community development, environmental education, sustainable urban design and planning (see Chap. 4). The urban population represents a huge potential, often largely untapped, to deliver creative ideas, skills and manpower to take care of these spaces and to maximize their contribution to the quality of urban life. In various places throughout Europe, urban foresters, local authorities and community workers as well as individual activists are placing a higher priority on urban greening and a greater emphasis on ensuring that many different groups get as much benefit from it, using approaches that tap into the energy and commitment among local people. Very different projects all over Europe owe their success to the active participation of citizens. Examples of local initiatives are tree planting schemes and clean-up days. There are positive experiences with partnerships between city authorities and residents for the establishment and the maintenance of green spaces around high-rise housing blocks, for example in four city districts of Sofia, Bulgaria (Van Herzele and Denutte 2002) and in the suburb of Holma in Malmo, Sweden (Beer et al. 2003).

Learning and the transformative potential of citizen science.

The number of collaborative initiatives between scientists and volunteers (i.e., citizen science) is increasing across many research fields. The promise of societal transformation together with scientific breakthroughs contributes to the current popularity of citizen science (CS) in the policy domain. We examined the transformative capacity of citizen science in particular learning through environmental CS as conservation tool. We reviewed the CS and social-learning literature and examined 14 conservation projects across Europe that involved collaborative CS. We also developed a template that can be used to explore learning arrangements (i.e., learning events and materials) in CS projects and to explain how the desired outcomes can be achieved through CS learning. We found that recent studies aiming to define CS for analytical purposes often fail to improve the conceptual clarity of CS; CS programs may have transformative potential, especially for the development of individual skills, but such transformation is not necessarily occurring at the organizational and institutional levels; empirical evidence on simple learning outcomes, but the assertion of transformative effects of CS learning is often based on assumptions rather than empirical observation; and it is unanimous that learning in CS is considered important, but in practice it often goes unreported or unevaluated. In conclusion, we point to the need for reliable and transparent measurement of transformative effects for democratization of knowledge production.

Towards Participatory Integrated Valuation and Modelling of Ecosystem Services under Land-use Change

The lack of consideration for ecosystem services (ES) values in current decision making is recognised as one of the main reasons leading to an intense competition and arguably unsustainable use of well-located available land. In this article, we present a framework for the Valuation Of Terrestrial Ecosystem Services (VOTES), aiming at structuring a methodology that is applicable for valuing ES in a given area through a set of indicators that are both meaningful for local actors and scientifically constructed. Examples from a case study area in central Belgium are used to illustrate the methodology: a stepwise procedure starting with the valuation of ES at present. The valuation of the social, biophysical and economic dimensions of ES is based on current land-use patterns. Subsequently, scenarios of land-use change are used to explore potential losses (and/or gains) of ES in the future of the study area. With the VOTES framework, we aim at (1) incorporating stakeholders’ inputs to widen the valuation process and increase trust in policy-oriented approach; (2) integrating valuation of ES with a sustainable development stance accounting for land-use change and (3) developing suggestions to policy-makers for integrating ES monitoring in policy developments.

Local Knowledge in Visually Mediated Practice

Visualization tools such as maps, models, and computer images are used increasingly as means of involving people more effectively. We examine how a visualization tool in the form of a map-based model may shape the knowledge local people bring to the planning table. The analysis was guided by the concept of mediated action as it has been developed in sociocultural theory. We found that local knowledge was conditioned by a complexity of factors, including the dynamic of actions that develop around the tool and the way of looking imposed by map-based representation. The suggestion being made is that visualization tools, although bringing people closer to the planning process, also disconnect them from their local knowledge base.Visualization tools such as maps, models, and computer images are used increasingly as means of involving people more effectively.

Different arguments, same conclusions: how is action against invasive alien species justified in the context of European policy?

The prevention and management of invasive alien species (IAS) has become a high priority in European environmental policy. At the same time, ways of evaluating IAS continue to be a topic of lively debate. In particular, it is far from clear how directly policy makers’ value judgements are linked to the European (EU) policy against IAS. We examine the arguments used to support value judgements of both alien species and invasive alien species as well as the relation between these value judgements and the policy against IAS being developed at European level. Our study is based on 17 semi-structured interviews with experts from EU policy making and from the EU member states Austria, Belgium, Germany and Hungary. We found that our interviewees conceived of IAS in very different ways, expressed a variety of visions of biodiversity and ecosystem services, and adhered to widely different values expressed in their perceptions of IAS and the impacts of IAS. However, only some of these conceptualizations and value judgements are actually addressed in the rationale given in the preamble to the European IAS Regulation. Although value judgements about IAS differed, there was considerable agreement regarding the kind of action to be taken against them.

Health Benefits of Nature Experience: The Challenge of Linking Practice and Research

While there is a growing base of knowledge concerning the health benefits of nature experience, this knowledge appears to be insufficiently translated into practice. The perceived gap between research and practice is often explained by a lack of hard evidence on the effects and mechanisms at work. In this chapter we argue that strengthening the evidence base is only one of the areas where more needs be done. Converting the evidence into practice is a process that requires concerted attempts with different kinds of effort, and should therefore be viewed from different perspectives. We examine the topic from three distinct perspectives: problem definition (who is responsible?); acceptability (what constitutes acceptable evidence?); applicability (can the evidence be used in practice?). Throughout, we use examples from various disciplinary fields to illustrate the significant challenges and complexities faced in joining practice and research.

How does biodiversity conservation argumentation generate effects in policy cycles

Arguments in the formulation, implementation and evaluation of biodiversity policy frame conservation in a range of ways and express interests that can be conflicting. Policy processes are cyclic and iterative by nature and as policies are constantly reformulated, argumentation has an important role at each policy stage. In this paper, we utilise the policy cycle model to shed light on biodiversity-related policy processes and the ways in which argumentation generates effects at different stages of these processes. The paper first draws on literature and the theory-driven assumptions are then illustrated with insights from four European case studies on different policy processes in which biodiversity conservation plays a role. The analysis shows that argumentation tends to evolve over the course of the policy cycle, and framing has a key role across the different policy stages. It is concluded that the ways in which arguments persist, accumulate, diffuse, and replace old arguments, should be the target of increased attention in policy analysis.

Health Benefits of Nature Experience: Implications of Practice for Research

This chapter takes the theories and applications discussed in the previous Chapters 5 and 6, and considers the implications for practice and research. It takes as a starting point the fact that practice in applying therapeutic benefits of access and exposure to nature is not simple and that the benefits can be obtained in a number of different ways. Moreover, a single area of green space may deliver many different benefits to different people in different ways. A scenario is used to demonstrate this. The other dimensions which affect therapeutic aspects concern the potential benefactors – their life stage, lifestyle and contextual factors. The issue of research and building up the evidence base is also considered, with project evaluation and action research being two of the most promising routes. This scene setting is then developed into a demonstration of some projects which apply knowledge about the benefits to health of green areas and which have been scientifically evaluated and the results of which can be used to improve practice in the future. In conclusion the chapter suggests that the accumulation of the evidence base is a cyclical process of practice based on current evidence followed by evaluation and modification of practice which is then evaluated and so on.
