Abstract The areal distribution of seismic ground-motion intensity in the city of Christchurch, New Zealand, during the 1994 Arthurs Pass Earthquake (ML 6.6) was evaluated using an intensity questionnaire together with local site amplifications inferred from seismic recordings and microtremors. In order to estimate the intensity in parts of the city where no intensity data were available, intensity data were compared to relative levels of shaking determined from both weak-motion and microtremor recordings. Weak ground-motion amplification factors were determined using ratios of ground accelerations at five sediment sites with respect to a rock site. Microtremor amplification factors were determined from horizontal-to-vertical spectral ratios at a 1-km spacing throughout the city. A positive correlation between weak-motion and microtremor amplification factors allowed extrapolation of microtremor amplification to estimated MM intensity (EMMI). EMMI ranged from 3 to 6 and was consistent with the questionnaire intensity and geological conditions and showed detailed information on the areal distribution of ground-motion intensity in the city.

Public spaces are defined as places that should be accessible to all inhabitants without restrictions. They are spaces not only for gathering, socializing and celebrating but also for initiating discussions, protesting and demonstrating. Thus, public spaces are intangible expressions of democracy—a topic that the paper tackles its viability within the context of Alexandria, case study Al-Qaed Ibrahim square. On the one hand, Al-Qaed Ibrahim square which is named after Al-Qaed Ibrahim mosque is a sacred element in the urban fabric; whereas on the other it represents a non-religious revolutionary symbol in the Alexandrian urban public sphere. This contradiction necessitates finding an approach to study the characteristic of this square/mosque within the Alexandrian context—that is to realize the impact of the socio-political events on the image of Al-Qaed Ibrahim square, and how it has transformed into a revolutionary urban symbol and yet into a no-public space. The research revolves around the hypothesis that the political events taking place in Egypt after January 25th, 2011, have directly affected the development of urban public spaces, especially in Alexandria. Therefore methodologically, the paper reviews the development of Al-Qaed Ibrahim square throughout the Egyptian socio-political changes, with a focus on the square’s urban and emotional contextual transformations. For this reason, the study adheres to two theories: the "city elements" by Kevin Lynch and "emotionalizing the urban" by Frank Eckardt. The aim is not only to study the mentioned public space but also to figure out the changes in people’s societal behaviour and emotion toward it. Through empowering public spaces, the paper calls the different Egyptian political and civic powers to recognize each other, regardless of their religious, ethnical or political affiliations. It is a step towards replacing the ongoing political conflicts, polarization, and suppression with societal reconciliation, coexistence, and democracy.

Geographical Dimension

The geographical dimension of urbanization is of major importance in depicting the influences of urbanization on the development of a city, since complex social-ecological systems interact in a multitude of ways at many spatial scales across time. This research introduced an indicator for assessing the spatial sustainability of a city from the perspective of landscape ecology, to provide a reasonable way for quantifying the spatial dynamic of the urban area of a city and how close the pattern of urban expansion close to a ‘compact’ way. A case study has been done in Xi’an. With the application of remote sensing technology, landscape ecology and other necessary software, the spacial sustainability of Xi’an from 1988 to 2010 were calculated, the rapid urbanization in Xi’an has significantly promoted the spatial sustainability of city from 1988 to 2000 and 2006 to 2010, whereas exerted negative effects on the spatial sustainability of the city from 2000 to 2006.

Post Disaster

The New Zealand government, following the Canterbury earthquakes 2010-2011, adopted new ways to rebuild the city. Given an opportunity to find solutions to pre-existing issues in the city, the government was keen to rebuild faster and better. The blueprint that was finalised mid-2012, had 17 anchor projects to lead its rebuilding efforts along with governance and legislative changes to facilitate rebuilding. Drawing on past literature using the case study of Canterbury earthquakes 2010-2011, this paper first reviews the rebuilding process in Christchurch. 14 face to face interviews were held with those involved in and subjected to these governance and structural changes. The study suggests the complex post-disaster environment limit the effectiveness of the imposed changes. Rebuilding efforts were hindered by the absence of a proper legislative framework, the ambiguity in defining roles and responsibilities of recovery agents, the time-pressure to rebuild resulting in hasty planning, limited public involvement in rebuilding and the lack of strategic relevance to ensure the outcomes are accepted by the public and fit with the city’s image in the long run. It is recommended that future research focuses on implications of post-disaster rebuilding practices on the wider community, businesses, and the government.

What and where is ‘the asylum’ today? To what extent do mental healthcare facilities stand out as clearly bounded entities in the modern urban landscape, perhaps reflecting their history as deliberately set-apart and then often stigmatised places? To what extent have they maybe become less obtrusive, more sunk into and interacting with their urban surroundings? What issues of urban ethics are at stake: concerning who/what is starkly demarcated in the city, perhaps subjected to exclusionary logics and pressures, or more sensitively integrated into the city, planned for inclusion and co-dwelling? These questions underscore our article, rooted in an in-depth case study of Gartnavel Royal Hospital, Glasgow, opened as a ‘lunatic asylum’ on its present, originally greenfield, site in the 1840s and remaining open today surrounded by dense urban expansion. Building from the ‘voices’ of patients, staff and others familiar with the site, we discuss the sense of this asylum as ‘other’ to, as ‘outside’ of, or merely ’beside’ the urban fabric. Drawing from concepts of ‘orientations’ (Ahmed, 2006), sites as spatial constructions (Burns &amp; Kahn, 2005), the power of borders and boundaries (Haselsberger, 2014; Sennett, 2018), issues of site, stigma and related urban ethical matters will be foregrounded. Where are the boundaries that divide the hospital campus from the urban context? What are the material signifiers, the cultural associations or the emotional attachments that continue to set the boundaries? Or, in practice, do boundaries melt into messier, overlapping, intersecting border zones, textured by diverse, sometimes contradictory, bordering practices? And, if so, what are the implications?

This paper will attempt to highlight the land reclamation as an instrument of urban planning. To achieve this goal, Dubai will be considered as a case study and, specially, Reima and Raili Pietilä’s proposal for the Deira Sea Corniche Competition as a visionary proposal which anticipated the creation of artificial islands in the city. Describing the history of the Dubai’s coastline and analyzing the Pietiläs’ project for its innovative and -at the same time- contextual ideas, the paper will not only offer a new way to approach urban design in Dubai but also to consider the value of land reclamation as a tool for urban development -with its strengths and weaknesses- in order to avoid land consumption and to allow the preservation of most part of the coastline.

Urban Resilience has recently emerged as a systematic approach to urban sustainability. The malleable definition of resilience has rendered its operationalisation an intriguing task for contemporary cities trying to address their organisational problems and confront uncertainty in a holistic manner. In this article we investigate the implementation challenges emerging for Resilient Strategies by the inattention paid to urban geological risk. We conceptualise urban geological risk as the combination of urban geohazards, geological vulnerability and exposure of the built environment and focus on the case study of Thessaloniki, Greece, a city that joined the 100 Resilient Cities initiative in 2014 and published its “Resilience Strategy 2030” (RS) in 2017. After a review of the RS, historical records of natural hazard events and with evidence gathered through interviews with city officials, we emphasize on earthquakes and surface flooding as the most relevant geohazards for Thessaloniki to tackle in its journey towards urban resilience. First, we examine geological vulnerability to earthquakes in conjunction with exposure of the built environment, as an outcome of ageing building stock, high building densities and the urban configuration, in Acheiropoietos neighbourhood, within the historic centre of the city. Then, we explore geological risk to surface flooding in Perea, in Thermaikos Municipality, with a particular focus on flash floods, by demonstrating how limited consideration of local geomorphology as well as semi-regulated urban expansion and its limited connection with emergency planning increase exposure of the built environment to surface flooding. Finally, we come up with the major implementation challenges Thessaloniki’s RS faces with regard to urban geohazards.

 Urban expansion of Kathmandu Valley is taking place at the fast rate challenging urban managers and planners of the city. In-migration has resulted in the unplanned urban growth of the city with the shortage of serviced land for urban development in Kathmandu. So Land Readjustment (LR) technique has been used as urban land development tool by the government. There are twenty two LR projects completed, and some of the projects are ongoing in the valley. The overview of the Land Readjustment technique of Kathmandu Valley has been done to explore the required measures needed to reform the existing legal and Institutional Framework and procedure of LR. Among the implemented LR projects, Nayabazar Land pooling has been selected for the case study as almost all the plots have been developed. Now, it is a dense residential neighborhood. The instruments used for research are literature study, in-depth interviews with different stakeholders of LR projects and landowners. Field visit and questionnaire survey in case study area are conducted regarding the street network and open space of the area. The existing system of LR technique is studied relating it with international experience mainly the case of Germany and Japan to draw positive inferences to explore the wider scope of LR technique for the comprehensive development in urban areas.

Urban population growth requires an appropriate and suitable place for future population to cope with the expected urban expansion of major cities in developing countries, and to identify an indicator urban expansion to guide planners, architects and decision makers, and help them reduce negative effects of city expansion with improvement in the ability to live in cities.  The density (population and building), fragmentation (saturation and openness) and compactness (proximity and cohesion) are the most important indicators of urban expansion of cities, which gives a clear perception of how city expands and possibility of adopting the most suitable ones when updating or preparing master lans. Most cities, especially Arab ones, suffer from excessive urban expansion, resulting in various urban problems affecting quality of life, services and city performance, which is the problem of research. This research is aimed at identifying factors influencing urban expansion of cities in developing countries when preparing for their future expansion, by analyzing the indicators of urban expansion of a set of cities to reach appropriate indicators for urban expansion sustainable future of the city to ensure orderly development of cities and make them more productive, more comprehensive and sustainable in upcoming decades.
