Designing sustainable and economically attractive brownfield revitalization options using an integrated assessment model

We describe the development of an integrated assessment model which evaluates redevelopment options of large contaminated brownfields and we present the application of the model in a case study. Aiming to support efficient and sustainable revitalization and communication between stakeholders, the presented assessment model integrates three pinnacles of brownfield revitalization: (i) subsurface remediation and site preparation costs, (ii) market-oriented economic appraisal, and (iii) the expected contribution of planned future land use to sustainable community and regional development. For the assessment, focus is set on the early stage of the brownfield redevelopment process, which is characterized by limited data availability and by flexibility in land use planning and development scope. At this stage, revealing the consequences of adjustments and alterations in planning options can foster efficiency in communication between the involved parties and thereby facilitates the brownfield revitalization process. Results from the case-study application indicate that the integrated assessment provides help in the identification of land use options beneficial in both a sustainable and an economical sense. For the study site it is shown on one hand that brownfield redevelopment is not automatically in line with sustainable regional development, and on the other hand it is demonstrated that additional contributions to sustainability are not intrinsically tied to increased costs.

Integrated planning and spatial evaluation of megasite remediation and reuse options.

Redevelopment of large contaminated brownfields (megasites) is often hampered by a lack of communication and harmonization among diverse stakeholders with potentially conflicting interests. Decision support is required to provide integrative yet transparent evaluation of often complex spatial information to stakeholders with different areas of expertise. It is considered crucial for successful redevelopment to identify a shared vision of how the respective contaminated site could be remediated and redeveloped. We describe a framework of assessment methods and models that analyzes and visualizes site- and land use-specific spatial information at the screening level, with the aim to support the derivation of recommendable land use layouts and to initiate further and more detailed planning. The framework integrates a GIS-based identification of areas to be remediated, an estimation of associated clean-up costs, a spatially explicit market value appraisal, and an assessment of the planned future land uses contribution to sustainable urban and regional development. Case study results show that derived options are potentially favorable in both a sustainability and an economic sense and that iterative re-planning is facilitated by the evaluation and visualization of economic, ecological and socio-economic aspects. The framework supports an efficient early judgment about whether and how abandoned land may be assigned a sustainable and marketable land use.

The Path From Passivity Toward Entrepreneurship Public Sector Actors in Brownfield Regeneration Processes in Central and Eastern Europe

Europeanization research dealing with the environmental transition in Eastern Europe has focused on the roles of state actors in adopting European regulations. Less well understood are the framings and roles of public administration actors when European Union regulations do not prescribe specific institutional changes. This article offers a micro perspective on the framings and roles of such actors in several cases of brownfield regeneration. Actors can play a proactive role, thereby fostering change, or they can play a moderately active or a passive role. We identify three moments—defining brownfield problems, mobilizing networks, and leading by example—which together define an entrepreneurial path. Along this path, actors can evolve from passivity toward entrepreneurship, but stasis and regression are also possible. Using qualitative data from the project TIMBRE (Tailored Improvement of Brownfield Regeneration in Europe), we illustrate different moments along this path for public sector actors in the Czech Republic, Poland, and Romania.

No perfect tools: Trade-offs of sustainability principles and user requirements in designing support tools for land-use decisions between greenfields and brownfields

The EU Soil Thematic Strategy calls for the application of sustainability concepts and methods as part of an integrated policy to prevent soil degradation and to increase the re-use of brownfields. Although certain general principles have been proposed for the evaluation of sustainable development, the practical application of sustainability assessment tools (SATs) is contingent on the actual requirements of tool users, e.g. planners or investors, to pick up such instruments in actual decision making. We examine the normative sustainability principles that need to be taken into account in order to make sound land-use decisions between new development on greenfield sites and the regeneration of brownfields - and relate these principles to empirically observed user requirements and the properties of available SATs. In this way we provide an overview of approaches to sustainability assessment. Three stylized approaches, represented in each case by a typical tool selected from the literature, are presented and contrasted with (1) the norm-oriented Bellagio sustainability principles and (2) the requirements of three different stakeholder groups: decision makers, scientists/experts and representatives of the general public. The paper disentangles some of the inevitable trade-offs involved in seeking to implement sustainable land-use planning, i.e. between norm orientation and holism, broad participation and effective communication. It concludes with the controversial assessment that there are no perfect tools and that to be meaningful the user requirements of decision makers must take precedence over those of other interest groups in the design of SATs.

Valuation of market uncertainties for contaminated land

The revitalization of contaminated land carries many risks and uncertainties. This paper aims to reveal drivers of risk perception and to introduce a novel valuation method for the assessment of market-perceived risks for sites polluted by earlier use in a transparent and comprehensible procedure. International approaches to account for value deductions due to contaminations and resulting uncertainties are reviewed. Based on literature review and a national survey amongst German professional appraisers, a risk assessment methodology is elaborated, outlined and applied in a case study approach. We find that areas that have been properly decontaminated on average still have a depressed market value of 12.25%. Quantities such as location, time and feasibility of passing on risks can be combined in an algorithm to determine the absolute value reduction for a specific property to be appraised. Results should help appraisers, international investors and portfolio managers to deepen their understanding of valuation of risks associated with (previously) contaminated land.

Risk-Averse by Nation or by Religion? Some Insights on the Determinants of Individual Risk Attitudes

Research findings have proven that the willingness to take risks is distributed heterogeneously among individuals. In the general public, there is a widely held notion that individuals of certain nationalities tend to hold certain typical risk preferences. Furthermore, religious beliefs are thought to explain differences in risk-preparedness on the individual level. We analyze these two possible determinants of individual risk attitudes: nationality and religion. First addressing the study of risk attitudes in a literature review, we then test our hypotheses empirically using the large, representative German Socio-Economic Panel (SOEP). To understand the importance of nationality, we focus on emigrants to Germany. The key findings are: (1) Nationality is not a valid determinant of risk attitudes. It can be broken down into several constituent factors including religion. (2) Religiousness is a significant determinant of risk attitudes. Religious persons are less risk-tolerant than atheists. Moreover, religious affiliation matters: Muslims are less risk-tolerant than Christians.

Costs of Implementing Agricultural Soil Protection Policies—Insights from Two German Cases

Abstract Transaction costs (TCs) are often claimed to be a key determinant of how policies are actually implemented on the ground and what effect they ultimately deliver on soil quality and functions. Focusing on agriculture-related soil protection policies in Eastern Germany, we analyse data from key informant interviews in two case study areas (Brandenburg and Saxony-Anhalt) in order to provide new evidence that TCs do indeed matter for policy implementation. We systematically map TCs that occur at the policy implementation and operation stages and their drivers. Our data showed that in addition to TCs for ‘information management’ and ‘coordination’, existing frameworks need to be extended to explicitly consider TCs for ‘enforcement’. Results illustrate that there is a broad range of TCs that are due to the complexity of soils and their management, property rights assignment and administrative processes. To some extent TCs in one policy arena can be reduced; however, often they are only superseded in place and time and, moreover, there are trade-offs between different kinds of TCs. The paper emphasizes that every assessment of effective policy implementation requires a specification of TCs and over what time frame they occur.

Soil and land use research in Europe: Lessons learned from INSPIRATION bottom-up strategic research agenda setting

We introduce the INSPIRATION bottom-up approach for the development of a strategic research agenda for spatial planning, land use and soil-sediment-water-system management in Europe. Research and innovation needs were identified by more than 500 European funders, endusers, scientists, policy makers, public administrators and consultants. We report both on the concept and on the implementation of the bottom-up approach, provide a critique of the process and draw key lessons for the development of research agendas in the future. Based on identified strengths and weaknesses we identified as key opportunities and threats 1) a high ranking and attentiveness for the research topics on the political agenda, in press and media or in public awareness, 2) availability of funding for research, 3) the resources available for creating the agenda itself, 4) the role of the sponsor of the agenda development, and 5) the continuity of stakeholder engagement as bases for identification of windows of opportunity, creating ownership for the agenda and facilitating its implementation. Our derived key recommendations are 1) a clear definition of the area for which the agenda is to be developed and for the targeted user, 2) a conceptual model to structure the agenda, 3) making clear the expected roles, tasks, input formats regarding the involvement and communication with the stakeholders and project partners, 4) a sufficient number of iterations and checks of the agenda with stakeholders to insure completeness, relevance and creation of co-ownership for the agenda, and 5) from the beginning prepare the infrastructure for the network to implement the agenda.

Teaching Energy Poverty

In many European countries, rising energy prices and depleting resources decrease the affordability of electric and heat energy for poor households (e.g. Scarpellini et al. 2015; Kolokotsa and Santamouris 2014)). The topic has been taken up in parts of the political arena in Europe following the UK’s example (Bouzarovski et al. 2012),especially in those countries where the affordability of energy has decreased drastically, such as in Greece (see Vatavali and Chatzikonstantinou in this volume) or Bulgaria, where skyrocketing energy prizes contributed to the fall of the government in 2013 (Parkinson, 2013). As Grosmann et al. (2014) and Haas (in this volume) show, the political debate in other countries such as Germany did not focus on the problems of households being overburdened by energy costs.
