Chase over the Nile: The Social Evolution of Riverine Landscape in Urban Egypt

Throughout its history, Cairo evolved as a regional metropolis that sprawls along the banks of the Nile accumulating narratives of evolving social landscape. Overlooking the Nile reflected a privileged social position and place for the urban elite. In spatial terms, the urban bourgeoisie tend to develop living havens in enclaves that are distant from the populace’s everyday life. Ironically, exclusive settlements only attract urban growth further in their direction. This chapter offers an analytical reading of the socio-spatial structure of Cairo following the emergence and decline of a series bourgeoisie quarters along the shores of the Nile. It reports urban narratives based on archival records, documents and investigation of historical texts and travelers’ accounts. This essay argues that cities are essentially social constructs in which hierarchy and connectivity are fundamental aspects of its economic and spatial logic. Through social ambition and desire for upgrade, middle class infiltrate into bourgeoisie havens and sometimes encircle it, seeking better living condition inscribed by social mobility and connectivity to centres of wealth and power. Being both natural barrier and cohesive spine, the Nile helped Cairo to develop successive nucleuses of highly crafted urban experiences that have left their imprints on the contemporary urban scene.

Authenticity, Identity and Sustainability in Post-war Iraq: Reshaping the Urban Form of Erbil City

Issues of authenticity and identity are particularly significant in cities where social and cultural change is shaping active transformation of its urban fabric and structure in the post-war condition. In search of sustainable future, Iraqi cities are stretched between the two ends of the spectrum, authentic quarters with its traditional fabric and modern districts with their global sense of living. This paper interrogates the reciprocal influences, distinct qualities and sustainable performance of both authentic and modern quarters of Erbil, the
capital of the Iraqi province of Kurdistan, as factors in shaping sustainable urban forms for Iraqi cities. In doing so, the paper, firstly, seeks to highlight the urban identity as an effective factor in relation to sustainable urban form. Secondly, the city of Erbil in Iraq has been chosen as a field study, due to its regional, social, political and historical role in the region. Thirdly, the study emphasises the dynamic activities and performance of residential projects according to rational sustainable criteria. The research concludes that urban identity and the sense of place in traditional and historical places should inform design strategies in order to achieve a more sustainable urban context.

Sequence stratigraphy related distribution of diagenetic alterations In Miocene deltaic and shoreface arenites, the Suez Rift, EGYPT.

The distribution of eogenetic alterations in shoreface-offshore and coarse-grained deltaic, calcarenite to hybrid arenites of the Mheiherrat Formation (lower Rudeis), Early Miocene, the Gulf of Suez, Egypt) can be constrained within a sequence stratigraphic framework. The bioclast-rich, shoreface (trangressive systems tract; TST) and shoreface (highstand systems tract; HST) arenites, particularly those below the parasequence boundaries and maximum flooding surface, are cemented by grain-coating microcrystalline, circumgranular isopacheous acicular and columnar, and coarse-crystalline calcite (δ18OVPDB = -3.6 to -0.3 ‰; δ13CVPDB = -2.3 to -0.7 ‰), non-Ferro an dolomite (δ18OVPDB = -3.9 to +0.9‰; δ13CVPDB = -2.5 ‰ to -0.7 ‰), and pyrite. Zeolite, palygorskite and gypsum occur in the HST shoreface arenites, being enhanced by aird climatic condations. The coarse-grained deltaic LST deposits are pervasively cemented by coarse-crystalline, pore-filling calcite and small amounts of microcrystalline calcite (δ18OVPDB = -4.4 to -2.3 ‰; δ13CVPDB = -2.8 to -1.3 ‰) and non-ferroan dolomite (δ18OVPDB = -4.8 to -2.5 ‰; δ13CVPDB = -3.3 to -1.5 ‰). Thus, this study demonstrates that changes in pore-water chemistry, which induced changes in the texture, composition and extent of cementation in the Miocene arenites was controlled by changes in the relative sea level and by the paleo-climatic conditions during deposition of the HST arenites.

Urban Oasis:Ajman as Event City

The Urban Oasis celebrates Ajman’s history as well as encourages a greater future. Stitching into the existing urban fabric of Ajman and the surrounding cities, the master plan provides an entrance that encases a number of different events. From studying other successful event cities, it became apparent the need for a variety of events over a yearly basis.

Sustainability is another key feature of the master plan. From the way the urban network of streets are formed and orientated to how energy is produced and conserved. Another sustainable aspect that drove the master plan was the retention of the camel track. An important and incredible event in itself, the camel track provides an opportunity to celebrate Ajman’s culture and retain an important part of its history.

Ecological dynamics of extinct species in empty habitat networks. 1. The role of habitat pattern and quantity, stochasticity and dispersal

We examined a remnant host plant (Primula veris L.) habitat network that was last inhabited by the rare butterfly Hamearis lucina L. in north Wales in 1943, to assess the relative contribution of several spatial parameters to its regional extinction. We first examined relationships between P. veris characteristics and H. lucina eggs in surviving H. lucina populations, and used these to predict the suitability and potential carrying capacity of the habitat network in north Wales. This resulted in an estimate of roughly 4500 eggs (ca 227 adults). We developed a discrete space, discrete time metapopulation model to evaluate the relative contribution of dispersal distance, habitat and environmental stochasticity as possible causes of extinction. We simulated the potential persistence of the butterfly in the current network as well as in three artificial (historical and present) habitat networks that differed in the quantity (current and X3) and fragmentation of the habitat (current and aggregated). We identified that reduced habitat quantity and increased isolation would have increased the probability of regional extinction, in conjunction with environmental stochasticity and H. lucina's dispersal distance. This general trend did not change in a qualitative manner when we modified the ability of dispersing females to stay in, and find suitable habitats (by changing the size of the grid cells used in the model). Contrary to most metapopulation model predictions, system persistence declined with increasing migration rate, suggesting that the mortality of migrating individuals in fragmented landscapes may pose significant risks to system-wide persistence. Based on model predictions for the present landscape we argue that a major programme of habitat restoration would be required for a re-established metapopulation to persist for > 100 years.

Ecological dynamics of extinct species in empty habitat networks. 2. The role of host plant dynamics

This paper explores the relative effects of host plant dynamics and butterfly-related parameters on butterfly persistence. It considers an empty habitat network where a rare butterfly (Cupido minimus) became extinct in 1939 in part of its historical range in north Wales, UK. Surviving populations of the butterfly in southern Britain were visited to assess use of its host plant (Anthyllis vulneraria) in order to calibrate habitat suitability and carrying capacity in the empty network in north Wales. These data were used to deduce that only a portion ( similar to 19%) of the host plant network from north Wales was likely to be highly suitable for oviposition. Nonetheless, roughly 65,460 eggs (3273 adult equivalents) could be expected to be laid in north Wales, were the empty network to be populated at the same levels as observed on comparable plants in surviving populations elsewhere. Simulated metapopulations of C. minimus in the empty network revealed that time to extinction and patch occupancy were significantly influenced by carrying capacity, butterfly mean dispersal distance and environmental stochasticity, although for most reasonable parameter values, the model system persisted. Simulation outputs differed greatly when host plant dynamics was incorporated into the modelled butterfly dynamics. Cupido minimus usually went extinct when host plant were at low densities. In these simulations host plant dynamics appeared to be the most important determinant of the butterfly's regional extirpation. Modelling the outcome of a reintroduction programme to C. minimus variation at high quality locations, revealed that 65% of systems survived at least 100 years. Given the current amount of resources of the north Wales landscape, the persistence of C. minimus under a realistic reintroduction programme has a good chance of being successful, if carried out in conjunction with a host plant management programme.

Listening to ‘Generation Jacobs’; A Case Study in Participative Engagement for a Child-Friendly City

This paper reflects on the enduring value of Jane Jacobs’ Life and Death of American Cities in the context of Child-Friendly Cities. This is explored through a project in Belfast which has engaged primary school children in how they understand their local environment. This shows that while children can effectively contribute to policy debates, there is a need to express this in a way that can be more effectively assimilated into planning debates. The paper reflects on this experience, suggesting that ‘Generation Jacobs’ could be used as a rhetorical device to frame children’s needs in a way that can be better understood by the planning profession.

City of Dreams? Belfast, planning and the ‘myth’ of development

The future of Belfast is found in its plans – beginning with 1945 planning proposals to the recently adopted Belfast Metropolitan Area Plan, these documents have aimed to encourage and channel urban development processes to secure collective outcomes that enhance the public interest. Central to this objective has been the idea of ‘development’ and in this paper we interrogate the representation of this concept in the urban discourse of Belfast. We seek to do this by first exploring how ‘development’ and associated concepts are articulated in key spatial policy documents and then contrast these with examples of some of the key physical, spatial outcomes of economic processes that have occurred in the last ten years. The paper will review the dominant trajectories of urban change in Belfast, consider their implications and relate these to the official goals and aspirations represented in planning strategies and regeneration visions for the city. In doing this we draw on the recent work of Marcuse (2015) to identify how ideas of ‘development’ and ‘growth’ have been used to anonymise, harmonize and homogenise the outcomes of these spatial processes. The paper will conclude by considering how Belfast’s urban discourse acts to suppresses alternative visions of the city and explores the potential consequences of this for the new governance arrangements for planning in Belfast.

City Profile: Erbil

Erbil (Hawler in Kurdish), is the capital and the largest city of Iraqi Kurdistan. Having been continuously inhabited for about 6000 years, the city has recently been regarded by UNESCO World Heritage as one of the world’s oldest urban settlements. The city is witnessing remarkable urban growth and rapid spatial expansion compounded by a dramatic increase in population due to emigration from the countryside and rural areas over the last three decades. Following the changing geopolitical landscape of post-war Iraq, urban changes and socio-political transformation are largely driven by Erbil’s growing autonomous status as the capital of northern region of Kurdistan since 2003. This paper explores the layers of historical, spatial and social developments of the contemporary urban context of Kurdistan in general and of Erbil in particular as a reflection of the changing status of the city, as well as the polarization of Iraq and the emergence of neoliberal urbanism. The tension between the global and modern from one side and traditional and authentic from another is ever present and evident in everyday challenges in the planning of the city. In large part, Erbil’s built fabric embodies the dichotomy of identity and contests between its past and future, in which the present remains a transition between two disconnected realities.

King David’s City at Khirbet Qeiyafa: Results of the Second Radiocarbon Dating Project

Fifteen samples of burnt olive pits discovered inside a jar in the destruction layer of the Iron Age city of Khirbet Qeiyafa were analyzed by accelerator mass spectrometry (AMS) radiocarbon dating. Of these, four were halved and sent to two different laboratories to minimize laboratory bias. The dating of these samples is ~1000 BC. Khirbet Qeiyafa is currently the earliest known example of a fortified city in the Kingdom of Judah and contributes direct evidence to the heated debate on the biblical narrative relating to King David. Was he the real historical ruler of an urbanized state-level society in the early 10th century BC or was this level of social development reached only at the end of the 8th century BC? We can conclude that there were indeed fortified centers in the Davidic kingdom from the studies presented. In addition, the dating of Khirbet Qeiyafa has far-reaching implications for the entire Levant. The discovery of Cypriot pottery at the site connects the 14C datings to Cyprus and the renewal of maritime trade between the island and the mainland in the Iron Age. A stone temple model from Khirbet Qeiyafa, decorated with triglyphs and a recessed doorframe, points to an early date for the development of this typical royal architecture of the Iron Age Levant.

Teenagers' Perceptions and Experiences of Belfast as a Divided City

In this ‘research project’ case study, we provide an empirical example of how quantitative and qualitative methods were combined within a single study and discuss some of the strengths and weaknesses of our combined methodology which included questionnaires, photo-prompts and focus-group interviews. Our intention in using mixed methods was to enhance understandings of the meanings of space, place and territory on the everyday lives of young people growing up in Belfast. How do young people negotiate space in politically divided cities such as Belfast? Is territory important, and if so, why is it important? How do we construct an appropriate and relevant study design that can not only describe, but explain what place, space and territory mean to young people, and more importantly, how it impacts on their everyday lives? How useful is it to apply a mixed-methods approach to finding answers to these questions? We explain why and how we used a mixed-methods approach and illuminate some of the issues we encountered. We demonstrate how mixed methods can provide not just complementary but also new insights into the topic under investigation. We hope that the case study encourages you to experiment, or at least consider, the potential of using mixed methods.

Demand-side characterisation of the smart city for energy modelling.

This paper presents a new methodology for characterising the energy performance of buildings suitable for city-scale, top-down energy modelling. Building properties that have the greatest impact on simulated energy performance were identified via a review of sensitivity analysis studies. The methodology greatly simplifies the description of a building to decrease labour and simulation processing overheads. The methodology will be used in the EU FP7 INDICATE project which aims to create a master-planning tool that uses dynamic simulation to facilitate the design of sustainable, energy efficient smart cities.
