"Ever-growing Amman", Jordan: Urban expansion, social polarisation and contemporary urban planning issues

Amman the primate capital city of the Hashemite Kingdom of Jordan currently has a population in excess of 2 million, but in 1924 it consisted of little more than a collection of dwellings and some 2000-3000 inhabitants. The present paper sets out to document and explain the phenomenal expansion of "ever-growing Amman". The physical geography of the urban region and the early growth of the city are considered at the outset and this leads directly to consideration of the highly polarised social structuring that characterises contemporary Amman. In doing this, original data derived from the recent Greater Amman Municipality's Geographical Information System are presented. In this respect, the essential modernity of the city is exemplified. The employment and industrial bases of the city and a range of pressing contemporary issues are then considered, including transport and congestion, the provision of urban water under conditions of water stress and privatisation, and urban and regional development planning for the city. The paper concludes by emphasizing the growing regional and international geopolitical salience of the city of Amman at the start of the 21st century. (C) 2008 Elsevier Ltd. All rights reserved.

Changing times, changing places: urban development and the politics of space - time

Much of the writing on urban regeneration in the UK has been focused on the types of urban spaces that have been created in city centres. Less has been written about the issue of when the benefits of regeneration could and should be delivered to a range of different interests, and the different time frames that exist in any development area. Different perceptions of time have been reflected in dominant development philosophies in the UK and elsewhere. The trickle-down agendas of the 1980s, for example, were criticised for their focus on the short-term time frames and needs of developers, often at the expense of those of local communities. The recent emergence of sustainability discourses, however, ostensibly changes the time focus of development and promotes a broader concern with new imagined futures. This paper draws on the example of development in Salford Quays, in the North West of England, to argue that more attention needs to be given to the politics of space-time in urban development processes. It begins by discussing the importance and relevance of this approach before turning to the case study and the ways in which the local politics of space-time has influenced development agendas and outcomes. The paper argues that such an approach harbours the potential for more progressive, far-reaching, and sustainable development agendas to be developed and implemented.

Resilience planning, economic change and the politics of post-recession development in London and Hong Kong

For much of the 1990s and 2000s, the emphasis of urban policy in many global cities was on managing and mitigating the social and environmental effects of rapid economic growth. The credit crunch of 2008 and the subsequent recession have undermined some of the core assumptions on which such policies were based. It is in this context that the concept of resilience planning has taken on a new significance. Drawing on contemporary research in London and Hong Kong, the paper shows how resilience and recovery planning has become a key area of political debate. It examines what is meant by conservative and radical interpretations of resilience and how conservative views have come to dominate ‘recovery’ thinking, with élite groups unwilling to accept the limits to the neo-liberal orthodoxies that helped to precipitate the economic crisis. The paper explores the implications of such thinking for the politics of urban development.

On the development of summer thunderstorms in the city of Sao Paulo: Mean meteorological characteristics and pollution effect

This study investigates how the summer thunderstorms developed over the city of Sao Paulo and if the pollution might affect its development or characteristics during the austral summer (December-January-February-March, DJFM months). A total of 605 days from December 1999 to March 2004 was separated as 241 thunderstorms days (TDs) and 364 non-thunderstorm days (NTDs). The analyses are performed by using hourly measurements of air temperature (T), web-bulb temperature (Tw), surface atmospheric pressure (P), wind velocity and direction, rainfall and thunder and lightning observations collected at the Meteorological Station of the University of Sao Paulo in conjunction with aerosol measurements obtained by AERONET (Aerosol Robotic Network), and the NCEP-DOE (National Centers for Environmental Prediction Department of Energy) reanalysis and radiosondes. The wind diurnal cycle shows that for TDs the morning flow is from the northwest rotating to the southeast after 16: 00 local time (LT) and it remains from the east until the night. For the NTDs, the wind is well characterized by the sea-breeze circulation that in the morning has the wind blowing from the northeast and in the afternoon from the southeast. The TDs show that the air temperature diurnal cycle presents higher amplitude and the maximum temperature of the day is 3.2 degrees C higher than in NTDs. Another important factor found is the difference between moisture that is higher during TDs. In terms of precipitation, the TDs represent 40% of total of days analyzed and those days are responsible for more than 60% of the total rain accumulation during the summer, for instance 50% of the TDs had more than 15.5mm day(-1) while the NTDs had 4 mm day(-1). Moreover, the rainfall distribution shows that TDs have higher rainfall rate intensities and an afternoon precipitation maximum; while in the NTDs there isn`t a defined precipitation diurnal cycle. The wind and temperature fields from NCEP reanalysis concur with the local weather station and radiosonde observations. The NCEP composites show that TDs are controlled by synoptic circulation characterized by a pre-frontal situation, with a baroclinic zone situated at southern part of Sao Paulo. In terms of pollution, this study employed the AERONET data to obtain the main aerosol characteristics in the atmospheric column for both TDs and NTDs. The particle size distribution and particle volume size distribution have similar concentrations for both TDs and NTDs and present a similar fine and coarse mode mean radius. In respect to the atmospheric loading, the aerosol optical depth (AOD) at different frequencies presented closed mean values for both TDs and NTDs that were statistically significant at 95% level. The spectral dependency of those values in conjunction with the Angstrom parameter reveal the higher concentration of the fine mode particles that are more likely to be hygroscopic and from urban areas. In summary, no significant aerosol effect could be found on the development of summer thunderstorms, suggesting the strong synoptic control by the baroclinic forcing for deep convective development.

Slow Cities: Sustainable Places in a Fast World

This article examines the Slow Food and Slow City movement as an alternative approach to urban development that focuses on local resources, economic and cultural strengths, and the unique historical context of a town. Following recent discussions about the politics of alternative economic development, the study examines the Slow City movement as a strategy to address the interdependencies between goals for economic, environmental, and equitable urban development. In particular, we draw on the examples of two Slow Cities in Germany—Waldkirch and Hersbruck, and show how these towns are retooling their urban policies. The study is placed in the context of alternative urban development agendas as opposed to corporate-centered development. We conclude the article by offering some remarks about the institutional and political attributes of successful Slow Cities and the transferability of the concept.

A CO2-saving-based methodology to measure the impact of the SUMP in European Cities: Application to the City of Burgos

Urban mobility in Europe is always a responsibility of the municipalities which propose measures to reduce CO2 emissions in terms of mobility aimed at reducing individual private transport (car). The European Commission's Action Plan on Urban Mobility calls for an increase in the take-up of Sustainable Urban Mobility Plans in Europe. SUMPs aim to create a sustainable urban transport system. Europe has got some long term initiatives and has been using some evaluation procedures, many of them through European projects. Nevertheless, the weak point with the SUMPs in Spain, has been the lack of concern about the evaluation and the effectiveness of the measures implemented in a SUMP. For this reason, it is difficult to know exactly whether or not the SUMPs have positively influenced in the modal split of the cities, and its contribution to reduce CO2 levels. The case of the City of Burgos is a very illustrative example as it developed a CiViTAS project during the years 2005-2009, with a total investment of 6M?. The results have been considered as ?very successful? even at European level. The modal split has changed considerably for better, The cost-effectiveness ratio of the SUMP in the city can be measured with the CO2 ton saved, specifically 36 ? per CO2 ton saved, which is fully satisfactory and in line with calculations from other European researchers. Additionally, the authors propose a single formula to measure the effectiveness of the activities developed under the umbrella of a SUMP.

Hybridization Processes: The case of the urban game: Hybrid Hunt: Petrified

The proposal highlights certain design strategies and a case study that can link the material urban space to digital emerging realms. The composite nature of urban spaces ?material/ digital- is understood as an opportunity to reconfigure public urban spaces without high-cost, difficult to apply interventions and, furthermore, to reactivate them by inserting dynamic, interactive and playful conditions that engage people and re-establish their relations to the cities. The structuring of coexisting and interconnected material and digital aspects in public urban spaces is proposed through the implementation of hybridization processes. Hybrid spaces can fascinate and provoke the public and especially younger people to get involved and interact with physical aspects of urban public spaces as well as digital representations or interpretations of those. Digital game?s design in urban public spaces can be comprehended as a tool that allows architects to understand and to configure hybrids of material and digital conceptions and project all in one, as an inseparable totality. Digital technologies have for a long time now intervened in our perception of traditional dipoles such as subject - environment. Architects, especially in the past, have been responsible for material mediations and tangible interfaces that permit subjects to relate to their physical environments in a controlled and regulated manner; but, nowadays, architects are compelled to embody in design, the transition that is happening in all aspects of everyday life, that is, from material to digital realities. In addition, the disjunctive relation of material and digital realms is ceding and architects are now faced with the challenge that supposes the merging of both in a single, all-inclusive reality. The case study is a design project for a game implemented simultaneously in a specific urban space and on the internet. This project developed as the spring semester course New Media in Architecture at the Department of Architecture, Democritus University of Thrace, Greece is situated at the city of Xanthi. Composite cities can use design strategies and technological tools to configure augmented and appealing urban spaces that articulate and connect different realms in a single engaging reality.

The "other" cities: urban planning and architecture for tourism: the case of the Spanish Mediterranean (1945-1975)

There we analyce the first touristic nucleus arouse in the Spanish Mediterranean coast between World War II and the Petroleum Crisis (1945-75). Special attention is payed to the characteristics of these new villages: the relation of their urban frame with nature -original or artificial- and the lack of industry. We make a distintion of three types: cluster nucleus (La Manga and El Saler), tridimentional urbanism (Playa de San Juan y Urbanova) and extreme typologies (Campoamor and Benidorm). With them the cities for vacations are discovered, mainly for second home purpouse (vacation home/holiday home). The panorama after the current crisis is a lineal chain of small urban settlements on the coast. Finally, Finally, we can see how these "secondary cities" without industry and specialized in leisure, are developing to our days until become new cities of services, doubling the existing ones; now they are "the other cities".
