The promotion of renewable energy sources (RESs) is a key European and national policy aimed at strengthening clean energy production, decoupling from fossil fuels, and responding to climate change commitments. Spatial planning is crucial as it can spatially direct the demand for investments in RESs, taking into account the challenges related to more efficient coexistence of RESs and environmental assets, both natural and manmade. Specific objectives, such as the definition of the carrying capacity concept, take on considerable importance in ensuring the balance between the demand for RESs and a number of other priorities. Small hydroelectric power stations (SHPSs), being spatially dependent on the existence of the natural resource (water), incorporate specific impacts in the areas of installation; namely, the watercourses. Taking into consideration the concept of carrying capacity for the areas where SHPSs are proposed to be installed by the Greek Special Spatial Planning Framework for RESs, which is limited to a linear/watercourse approach, this paper proposes a new complementary approach, that of “territorial” carrying capacity. The former involves the negotiation of terms and conditions for siting an SHPS within the narrow range of a water body (watercourse), while the latter, as proposed in this paper, attempts to capture the problem at the level of the wider territory or the functional area of a catchment, an approach that places carrying capacity in a more strategic spatial planning context.

Climate change adaptation has become an important policy domain, as it has the potential to substantially reduce many of the adverse impacts of climate change. Several scientific terms and general concepts have been used to comprehend adaptation, including vulnerability, exposure, sensitivity, adaptability, and resilience. However, most of these concepts are often used in inconsistent ways and their relationship is to a large extent unclear. As a result, there is a lack of clear understanding of adaptation and its practical implementation in fields such as spatial planning, whose role in tackling climate change, especially through ecosystem approaches, is critical. This paper attempts to investigate the practical integration of adaptation in the context of spatial planning, specifically through Green Infrastructure (GI) planning. Applying a thematic analysis to 91 scientific and major policy documents, the main determinants of the critical concepts that relate to adaptation were identified, classified, and intertwined with key determinants of GI planning and design. The analysis led to the development of a methodological tool, named REAd GrIn. This model can be used to prepare and evaluate spatial plans and policies, which integrate the concepts of resilience, vulnerability, and adaptability to achieve adaptation through spatial planning.

Transit-oriented development (TOD) is an integrated urban and transport planning approach that aims to mitigate urban sprawl and car use, enhance neighborhood livability, increase public transport use, and promote sustainable mobility. Although TOD is widely accepted by academics, planners, and policymakers, the question of how citizens acknowledge its expected benefits remains open. This paper explores citizen satisfaction and perceptions of their neighborhood and investigates their awareness of TOD’s potential for sustainable revitalization and regeneration of metro areas in Thessaloniki, a compact Mediterranean city that is introducing a new urban rail system. Our research is based on a questionnaire survey, conducted within the catchment areas of two future metro stations, which present different spatial and socio-economic characteristics. For the data analysis, we use inferential statistics analysis and ordinal logistics regression to investigate the variations in citizens’ perceptions. Findings reveal that even if there is a statistical difference between people’s perceptions regarding the main spatial features of their neighborhoods, respondents in both areas express similar major concerns about public space, walkability issues, transit quality, and the positive effects that the metro could offer regarding urban revitalization and development. Furthermore, age, income, and personal travel behaviors appear to be significantly related to the level of satisfaction with public transport and the willingness to increase transit use because of the metro. We argue that citizens’ pre-construction surveys can support local policy makers in tailing and optimizing a TOD project implementation based on the community’s needs and priorities. Such surveys operate as knowledge production platforms to strengthen policy efficiency and reinforce the feelings of trust between citizens and local policy makers.

Urban regeneration has been at the forefront of urban planning and development in European cities for many decades and is strongly connected to property-led development, with the involvement of various stakeholders. In Greece, urban regeneration, as a public policy response to large-scale abandonment and dereliction of urban land, has not been successful so far. The Greek planning system and its provisions for renewal of degraded urban areas have for long been regarded as an obstacle to the implementation of urban regeneration projects. The reform of the planning system in the 2010s introduced some critical changes, with an emphasis on larger-scale development, but with no particular focus on urban regeneration. Using two case studies of regeneration projects in the city of Thessaloniki, this paper attempts to provide an insight into the role of the various stakeholders in such projects. It is argued that in these projects, each stakeholder, irrespective of its character, acts as distinct interest group which develops only binary relations with other stakeholders. Thus, the regeneration project becomes a platform upon which each stakeholder aims to secure its power, instead of a coordinated multi-stakeholder process with a framework for sharing the costs and benefits of its implementation.

Shaping livable cities is an enduring issue for urban planning, which came dramatically to the forefront of relevant policies with the coronavirus disease (COVID-19) pandemic. This study explores what makes cities livable by using neighborhood satisfaction and neighborhood happiness as measures of urban livability. The determinants of neighborhood satisfaction and neighborhood happiness are examined and compared, using geospatial and survey data from two cities, one from the South and the other from the North European context: Thessaloniki, Greece and Oslo, Norway. A structural equation model is developed and tested. In both cities, common determinants of neighborhood satisfaction are found to be the proximity to city center, neighborhood perceived safety, and place attachment, whereas common determinants of neighborhood happiness are found to be neighborhood perceived safety, neighborhood perceived quietness, neighborhood social cohesion, place attachment, and lower neighborhood density. Important differences between the two cities were also observed. Numerous local amenities seem to positively contribute to urban livability in Thessaloniki, but not in Oslo. Parks and trees are positively linked to neighborhood happiness in Oslo, but not in Thessaloniki. These differences support the view that some of the links between neighborhood characteristics and livability depend on the local context related to local culture, attitudes, and preferences, all of which might also be influenced by the local built environment.

Rapid expansion of settlements and related infrastructures is a global trend that comes with severe environmental, economic, and social costs. Steering urbanization toward well-balanced compactness is thus acknowledged as an important strategic orientation in UN Sustainable Development Goal 11 (SDG-11) via the SDG-indicator &ldquo, Ratio of land consumption rate to population growth rate.&rdquo, The EU&rsquo, s simultaneous commitment to being &ldquo, a frontrunner in implementing [&hellip, ] the SDGs&rdquo, and to striving for &ldquo, no net land take until 2050&rdquo, calls for relating the concepts of land consumption and land take to each other. Drawing on an EU-centred questionnaire study, a focus group and a literature review, we scrutinize definitions of land consumption and land take, seeking to show how they are interrelated, and questioning the comparability of respective indicators. We argue that conceptual clarifications and a bridging of the two notions are much needed, and that the precision required for definitions and applications is context-dependent. While approximate understandings may suffice for general communication and dissemination objectives, accurate and consistent interpretations of the discussed concepts seem indispensable for monitoring and reporting purposes. We propose ways of addressing existing ambiguities and suggest prioritizing the term land take in the EU context. Thereby, we aim to enhance conceptual clarity around land consumption and land take&mdash, a precondition for solidly informing respective policies and decisions.

Land ownership determines fundamental interests, prescribing a framework of alliances and oppositions around its development and use. The public sector constitutes one of the main categories of large landowners, although this type of ownership takes more than one form, due to the wide variety of public sector bodies holding property. Public land management became one of the focuses of austerity policies in many European countries after the burst of economic crisis in 2008–2009, externally imposed in those countries that went through bailout programmes. In Greece, the history of land policy shows that a fundamental objective of state policy was the distribution and liquidation of public land, a policy that contributed to the formation of an extensive system of small land ownership. From 2010 onwards, a plethora of formal legislation sought to accelerate development procedures for the remaining large-scale public property, as a background resource to attract large-scale, so-called “strategic”, investments. This paper explores the critical characteristics and outcomes of the reforms to transform public land policy, identifying the interactions with urban planning, before and during the economic crisis. Taking a longer temporal view, the paper highlights the entrenched relationships existing between public land policy, urban planning and property development processes and their significance in the diachronic continuities often concealed in major policy reversals and reforms. It argues that ultimately there is a lack of a coherent and sustainable public property valorisation policy, being deprived of any institutional innovation for new forms of urban development, as well as of social acceptance.

Strategic spatial planning, in its widely accepted theoretical conceptualisation, has become the terrain for making balanced decisions about the consolidation of both a city’s international competitiveness and its role in a wider international context. Thus, it has emphasized shared responsibilities between the public and the private sector in economies where the roles of the public and the private sphere are clearly complementary. In countries with weaker institutional settings such distinctions are purposely obscure, as both spheres are enmeshed in statist and rent-seeking structures. Based on an investigation of the strategic spatial plans prepared over the past 15 years for the city of Thessaloniki the present paper attempts to explain the specificities and failures of strategic spatial planning in the Greek institutional environment, within the context of four defining features of the Greek local state, namely: (i) the centralization of the Greek government; (ii) the funding arrangements of l...

One of the problems urban areas are facing is the coupled effect of climate change and the Urban Heat Island (UHI) effect. This article attempts to demonstrate the potential of spatial planning to reduce the UHI effect and, hence, to contribute to climate change adaptation in compact urban areas. After a brief review of the relevant literature, the article focuses on one case study within the compact urban area of the city of Thessaloniki. The geographical, socio-economic and urban form data of the study area and its subsequent vulnerability to UHI were initially assessed. Based on these features, a local spatial planning strategy is proposed, and the study proceeds to a detailed amendment of the land use plan, within part of the vulnerable zone. This takes into account the existing urban form, the lack of resources and the availability of the spatial planning tools within the Greek spatial planning system. Τhe main purpose of this article is to highlight the fact that, even in urban areas where the potential for intervention seems to be marginal, because of their existing form, the complexities of the local planning system and resource limitations, improvements to the UHI effect and adaptation to climate change can be achieved by better land use planning and urban design.

The structure of a settlement network has been influenced historically by physical, geographical and socioeconomic factors. Theories of spatial development have focused on the interaction between urban areas and socioeconomic processes considering the natural surroundings as a steady parameter rather than a potentially varying element contributing to spatial development. Over the past 25 years in Greece, a number of socio-economic factors along with improvements in transport infrastructure led to crucial changes in the traditional settlement system. The development of new economic activities was often associated with the special characteristics of the natural landscape. In this way, natural landscape as a dynamic element interacts with the built environment and the economic activities of a place, leading to the formation of new clusters of relationships. Using the case study of the Region of Western Macedonia, a mountainous, border zone Greek region, and based on an interactive framework of analysis whereby human and natural systems are considered strongly interconnected, this paper examines the spatial interactions between the settlement network, as the basic representation of human activity, the natural landscape, as a crucial element of the natural system, and the dynamic zones of economic activities, as a parameter that encompasses crucial attributes of both human and natural systems. The paper proposes that the heterogeneity of these interactions and the way they affect the thresholds and resilience of a specific place are important for the understanding of spatial change and for an integrated spatial planning for sustainable development.
