Indisputably, urban design and soil sealing are parameters that can either aggravate or mitigate the urban heat island phenomenon, observed in dense urban environments around the world. Large sealed surfaces have been extensively reported to induce higher surface temperatures. The aim of this work is to answer a critical scientific question: on what extent do actually sealed soils contribute to the urban heat island. As an example, a case study was developed for the case of Nicosia – a city that experiences high urban heat island intensities due to its geographical location and its continuous urban growth. Three scenarios were developed with ranging percentages of unsealed surfaces – 0%, 20% and 40% of vegetation coverage and were simulated in an established microclimate modelling tool ENVI-met. The effect of the urban design and soil sealing in the investigated scenarios was analysed by presenting the results for a range of parameters, including ground- and canopy-level temperatures, diffused and reflected radiations, relative humidity, wind speed and sky view factor. The results indicated that the most effective scenario is the case where 40% of the ground is unsealed, primarily due to the impact on the canopy-level temperature and the wind speed. The authors believe that more attention should be drawn to this alarming topic by both policy-makers and researchers.

The article approaches different concepts of Large Urban Developments (LUDs) as products of the notion of a “spatial fix” (Harvey, 2001), which explains why built or natural environments can be deployed in the process of creating opportunities for new investments. Greece and Cyprus are two countries in the south of the European Union that underwent delayed urbanisation and significant land fragmentation in the form of small size private ownerships and with limited experience in comprehensive development. Greece has adopted a well-structured but complex spatial planning system, bureaucratic with limited effectiveness, adaptability or flexibility of delivery processes. On the other hand, Cyprus has a flexible but centralized system, effective in processing change but problematic in regulating quality in the built environment. Both countries recently experienced major financial crises. In the early 2010s, both governments promoted, as part of an economic recovery policy, extensive real estate development on public or privately-owned land with emphasis on LUDs as ways of addressing economic shortfalls. Inappropriately, LUDs have been primarily “conceived” as opportunities to attract foreign investments rather than a means of tackling crucial current deficiencies. New spatial planning frameworks merely add greater “flexibility” to the system in order to accelerate large private real estate investment. The article attempts to reveal, through case studies’ reviews, the impact of LUDs in countries with no infrastructure or experience in accommodating large-scale investment. It explores how the experience in Greece and Cyprus differs in terms of the relevant legislation adopted, the effectiveness in fulfilling its primary objective in attracting investment, and what are the possible social and environmental consequences on the planning acquis.

This article examines the interactions between digital and social media as the contemporary incubators of place perceptions and the critical debate of environmental quality. Digital and social media may change the way people live but not the way they use physical spaces. This indirect reading of place acts in terms of perceptual understanding in a number of ways, but, most importantly, it becomes fundamental in the “construction” of the sense of place. This is because it impacts on the way information is associated with reality or a contract of the reality which is generated through its “interference” with our intellectual and emotive understanding of place. At the same time, the politics of a new “sociality” contains participations and exclusions. The article adopts comparative case study research as the methodological approach for investigating notions of how urban space is perceived through the case study of Eleftheria Square in Nicosia, a controversial urban regeneration project that generated an extensive debate through digital and social media in Cyprus during the last two decades. It is an attempt of a parallel decoding of (i) a more formal or directive view through digital newspapers’ survey and (ii) an informal view through a Facebook group content analysis. Through the case study, the inefficiencies and potentialities of the new media tools in informing the wider public are clear by providing at the same time evidence of their priorities, preferences, and fears. The article comes to two basic conclusions: (i) the perceptions of urban projects through digital media are not static but fluent and constantly updated, usually turning positive as projects are completed and experienced; and (ii) the interactive and synchronous nature of social media provides a more accurate and updated picture of the society’s changing perceptions of public space.
