The paper reviews the study and use of urban consolidation centres (UCCs) which are a freight transport initiative intended to reduce goods vehicle traffic, vehicle-related greenhouse gas emissions and local air pollution. An international literature review has identified 114 UCC schemes in 17 countries (12 in the European Union (EU) and 5 outside the EU) that have been the subject of either a feasibility study, trial or a fully operational scheme in the last 40 years. The period from 2006 to 2010 has been the most active 5-year period in terms of UCC study, trial and scheme generation since the first UCC study was carried out in the early 1970s. Five countries account for the majority of all the 114 UCC schemes identified: France, Germany, Italy, the Netherlands and the UK. The vast majority of UCCs serve either all or part of an urban area. Examples of UCCs serving a single property (such as an airport or shopping centre) and construction sites have also been identified. Key organizational, operational, and financial issues that are critical to the success of UCCs are discussed. The traffic and environmental impacts of UCC trials and fully operational schemes are also reviewed.

The chapter considers the role that urban consolidation centres (UCCs) can play in helping to reduce goods vehicle traffic and its environmental impacts in urban areas. A UCC is a logistics facility that is situated in relatively close proximity to the area that it serves. Goods destined for this area are dropped off at the UCC, and are sorted and consolidated onto goods vehicles for delivery to their final destinations, often using environmentally friendly vehicles such as electric and gas-powered goods vehicles, and electrically-assisted cycles. The development of UCCs since their first appearance in the 1970s is reviewed and the various types of UCC categorised. The freight transport and logistics advantages offered by UCCs are discussed. Case studies of four recent UCC trials are included. The objectives, operational and financial aspects and impacts of these UCCs are compared and their critical success factors identified.

This paper reviews the options available to policy makers in their efforts to reduce the negative impacts of urban freight transport. After providing a summary of the categories of negative impacts that can be targeted together with the specific policy initiatives available, it reviews the actions taken by policy makers across in cities within four countries (UK, Japan, the Netherlands and France). In the case of the UK and Japan attention is focused on a single city as an exemplar of some of the developments. In the case of the Netherlands and France the discussion is wider.

The slogan ‘capitalism is crisis’ is one that has recently circulated swiftly around the global Occupy movement. From Schumpeter to Marx himself, the notion that the economic cycles instituted by capitalism require periodic crises as a condition of renewed capital accumulation is a commonplace. However, in a number of recent texts, this conception of crisis as constituting the very form of urban capitalist development itself has taken on a more explicitly apocalyptic tone, exemplified by the Invisible Committee's influential 2007 book The Coming Insurrection, and its account of what it calls simply ‘the metropolis’. ‘It is useless to wait’, write the text's anonymous authors, ‘for a breakthrough, for the revolution, the nuclear apocalypse or a social movement.… The catastrophe is not coming, it is here.’ In considering such an apocalyptic tone, this paper thus situates and interrogates the text in terms both of its vision of the metropolis as a terrain of total urbanization and its effective spatialization of the present as itself a kind of ‘unnoticed’ apocalypse: the catastrophe which is already here. It does so by approaching this not only apropos its place within contemporary debates surrounding leftist politics and crisis theory but also via its imaginative intersection with certain post-1960s science fiction apocalyptic motifs. What, the paper asks, does it mean to think apocalypse as the ongoing condition of the urban present itself, as well as the opening up of political and cultural opportunity for some speculative exit from its supposedly endless terrain?

Urban sprawl is a challenge to the sustainability of many cities around the world. Fragmented urban development and vacant land are widespread problems in many Arab cities (UN-Habitat, 2012) which are, according to Ben-Hamouch, mainly a result of inappropriate modern planning and poor land management (2013). This study addresses the problem of urban fragmentation at the neighbourhood level and examines to what extent the concept of compact urban form can contribute to the improvement of social and environmental sustainability in the Libyan city of Benghazi and Arab cities in general. The objectives and scope of the study have justified a morphological approach, where eleven case studies that present different urban typologies in the city have been investigated. The research strategy and selection of case studies were driven by the availability of data and meant to cover the main urban types and important issues defined within this context. This research, which has been conducted to explore and explain the relationships that exist between local urban forms and their performance in terms of sustainability, has produced valuable knowledge and helped to identify measures which target the improvement of people’s quality of life and environmental sustainability of the city. The research draws on the argument that adopting a type of human scale urban form, which is relatively compact and dense, well-connected and comfortably diverse, coupled with concepts of urban greening and flexible development relevant to the local context, would help to create a high quality urban form that is liveable and accessible, while causing minimum damage to the natural environment. This work is an attempt to respond and add to the ongoing debate on sustainable urban form in the developing countries (see: (Jenks, 2000)). The findings have contributed to the understanding of urban fragmentation and highlighted the relevance of the theory of compact city to sustainable development in Benghazi and the South in general. It is anticipated that this work would raise awareness on the impact of urban fragmentation on the sustainability of the built environment within this context and help to advance research on planning theory and practice based on real-life experience and responses to local circumstances.

The paper considers how urban consolidation centres (UCCs) can be used in the supply chain to reduce goods vehicle traffic and its associated environmental impacts, while also helping to make supply chains more responsive and efficient and thereby generate commercial benefits. The role of UCCs is presented and the various types discussed. The potential supply chain impacts of UCCs are considered. Case studies of six UCC schemes and trials are included, with their objectives, operational characteristics and impacts compared. The critical success factors associated with UCCs are identified.
