The modified law of Iranian Administrative divisions has greatly altered the pattern of settlement in recent decades. The promotion of rural areas to urban areas has shifted from mere population standard to combined population-administrative standards. However, all censuses suggest that many rural areas reported as smaller than the minimum population standard have been promoted to urban areas. In the last two decades, this is a clearly prominent phenomenon in the urban system of Iran. This paper evaluates the effects and consequences of promoting small and sparsely populated rural areas to urban areas in the Bushehr province. The used methodology is analytic-descriptive using a questionnaire distributed among 380 members of the target population. Data analysis is conducted in physical, economic, social and urban servicing domains using one-sample T-test and the utility range. The results show that promotion of rural areas to urban areas has positive outcomes such as improved waste disposal system, improved quality of residential buildings, increased monitoring of the construction, increased income, prevented migration and improved health services. However, the results of utility range show that the negative consequences of this policy are more than its positive outcomes, which have been studied in detail.

The chapter presents a case study based on transdisciplinary research, which was conducted at the Faculty of Architecture in Podgorica and is an innovation in architectural and urban practice of higher education in Montenegro. The study is based on the view that autonomous action of disciplines in the case of architecture and urbanism as multidisciplinary activities is limited, and an integrated approach to solving complex problems in the urban system is required. A global approach to research and solving urban issues is an important actor of sustainable development, where universities are central in this process. Collaborative educational discourses with a high degree of cooperation can develop an adequate platform for responses to the complex issues of the urban system. Producing experts with a developed awareness of a comprehensive understanding of the problem and transdisciplinary collaborative knowledge can strongly contribute to sustainable improvement, control, and management of urban spaces.

The fifth chapter, on products, deals with the global urban literatures around infrastructure, including both physical infrastructure and the economic understanding of infrastructural interconnections of the global urban system. While physical infrastructure dominates in Chinese investments in the global South, southern urban theory has turned attention to people-as-infrastructure. Books and articles about infrastructure in the global South for a decade or more have argued for seeing infrastructure as vital, lively, or alive, including human and nonhuman agency, and this chapter seeks to connect with this trend. It concentrates on trade and foreign direct investment from China in Africa, with a detailed case study of Zanzibar. It then examines the experiences and socio-material infrastructures of African traders in Guangzhou and the PRD.

Urban Villages

Urban villages play an important role in providing affordable housing to urban migrants in Chinese cities. They are considered as supplementary to the dual rural-urban system in China. Of central importance to studying urban villages is how the morphology of these informal settlements affects urban life. It is essential for urban planners and designers to examine the morphology of urban villages. This paper, therefore, investigates the morphology of urban villages using the case study of Dayuan Village in Guangzhou, China. The morphology of this urban village is tested against four main elements of urban morphology: urban density, accessibility, functional mix, and urban interface. Our results revealed that the type of street within the urban village has considerable influence on accessibility, functional mix, and urban interface. Regarding urban density, our results show that buildings’ height is not influenced by the centrality of buildings nor land value; however, it is likely that it is affected by planning agreements between the village committee and the local government. Land coverage does not comply with the planning regulation for residential districts. Regarding accessibility analysis, the number of entrances to streets is influenced by the type of street under analysis. The distribution of different types of functional mix is also affected by the type of street within the urban village. The buildings with a mix of ‘live/visit’ are concentrated along the formal streets and primary inner streets. The mono-functional use of ‘live’ and the bi-functional mix of ‘live/work’ are mostly located in the secondary inner streets. Regarding urban interface, our results demonstrate that the formal streets have an interface with considerable porosity, and that this can contribute to the livelihood of the immediate area.

In international literature, small cities are often presented as the weak link within the urban system due to their lower growth rate and the threat of shrinking in the context of metropolisation. However their population dynamics are highly variable between places, determined by a number of factors, such as the national and regional demographic trends or the local economic base. This article proposes a regional case study on Western France, examining their demographic changes from 1990 to 2015. Three possible factors based on underlying assumptions are tested: 1. the proximity of larger cities as a possible revitalisation factor due to urban sprawl; 2. The vicinity of the coast attributed to the growing role of residential attractiveness; 3. In a more original way, the distance to a railway station as a potential factor, boosted by the recent passenger railway service strengthening. The results are counter-intuitive and the assumptions only partially validated, which invites us to reassess the relevance of the analysis of urban dynamics by size class.

Abstract. Flood events are the most frequent cause of damage to infrastructure compared to any other natural hazard, and global changes (climate, socio-economic, technological) are likely to increase this damage. Transportation infrastructure systems are responsible for moving people, goods and services, and ensuring connection within and among urban areas. A failed link in this system can impact the community by threatening evacuation capability, recovery operations and the overall economy. Bridges are critical links in the wider urban system since they are associated with little redundancy and a high (re)construction cost. Riverine bridges are particularly prone to failure during flood events; in fact, the risks to bridges from high river flows and bank erosion have been recognized as crucial at global level. The interaction among flow, structure and network is complex, and yet to be fully understood. This study aims to establish rigorous practices of Computational Fluid Dynamics (CFD) for modelling hydrodynamic forces on inundated bridges, and understanding the consequences of such impact on the surrounding network. Objectives of this study are to model hydrodynamic forces as demand on the bridge structure, to advance a reliability analysis of the structure under the modelled loading and to assess the overall impact at systemic level. The flood-prone City of Carlisle (UK) is used as case study and a proof of concept. Implications of the hydrodynamic impact on the performance and functionality of the surrounding transport network are discussed. This research will help to fill the gap between current guidance for design and assessment of bridges within the overall transport system.

Functional Areas

The spatial economy can be visualised as a web of overlapping markets or functional areas linked to different activities. Unfortunately, very often administrative regions and local authority areas are used as proxies for functional areas, but they have serious shortcomings for spatial economic analysis and the implementation of local policies. The spatial economy is viewed here as a complex network of economic flows within a hierarchical urban system. This paper constructs a comprehensive geography of functional economic areas by first using consistent criteria based on commuting and migration flows for England. The analysis next superimposes a central place hierarchy derived from retail sales and office centre rents. It then classifies these functional economic areas offering insights into the spatial economy of England. The geography queries the relevance of core/surrounding models of urban form as large local labour market areas comprise in some cases more than 20 housing market areas. While the research uses England as a case study, the analysis is of generic significance to the spatial economies of developed countries. The paper also raises a number of methodological and data issues for further development.

The Cost

Based on the analysis of the cost of urbanization, this paper constructs the econometric model for broad and narrow sense economic cost of regional eco-urbanization, and carries out case study on urban system of Poyang Lake Eco-economic Zone. The results indicate that we should highlight the construction of small towns, and take a development road of new urbanization of balance development of large, medium-sized and small cities and towns. The Econometric model for cost of regional eco-urbanization provides a new quantitative and practical method for the study of urbanization, and this paper provides a practical way for urbanization development of undeveloped areas.
