Urban System

There are different attributes which are instrumental in shaping the characteristics of a city. Sustainable urban development is not possible without understanding the relationship among these attributes. And it is not possible to assess and quantify the interdependence of these attributes using a unidimensional approach. Hence, this chapter attempts to develop an understanding about the need of analyzing a city using principles of system sciences. However, there are a few issues with this approach which may escalate complexity in characterizing a city. Therefore, it further addresses the possibilities of uncertainty and randomness due to this approach. And it also explained about the possible ways to contain randomness and uncertainty in studying cities. It is believed that this chapter would succeed in developing a strong understanding about the working of cities, and the need of system science principles in investigating them.

Correct representation of characteristics of different attributes of a city helps in understanding the impact of these attributes on evolution of a city. And the way they are dependent on each other. It may further help in identifying the factors which can be a potential threat to sustainable urban development. This chapter aims to develop an understanding about the meaning and significance of characterization of a city, or say, an urban system. In addition, it provides detail about the approaches which can be adopted for characterizing an urban system. It is expected that this chapter will succeed in developing a good understanding about the need and significance of accurate and effective characterization of a city in the context of sustainable urban development.

During Afghanistan’s rapid urban growth, development diversified from state-run initiatives to ones led by local municipalities or nongovernmental entities such as private enterprises. Owing to these various efforts, cities face environmental challenges, squatter settlements, and unbalanced development. Responding to these interconnected challenges, cities need to increase their resilience to deal with the combined effects of urbanization, changing geopolitical contexts, and culture. In this study, we focused on dimensions of culturally responsive solutions for the built environment in Kabul, Afghanistan. Culture, as a key element in the concept of sustainable development, refers herein to the relationship between Afghan customs and belief systems as it influences and shapes the architecture of the urban environment. Initially, the study provides a conceptual understanding of sustainable urban development and the importance of culture. We have attempted to approach urban segregation in Kabul based on socioeconomic factors and address the essential role of culture in this unique context. Such segregation can be hazardous to both the current and future sustainability of urban development. To conclude, we provide in-depth insights into the contribution of culture and propose culture as a possible dimension of sustainability and an integral part of environmental, economic, and social dimensions of development.

Cycling is known to be environmentally friendly and beneficial to public health and sustainable urban development. Cycling has recently increased in Chinese cities as a result of the emergence of station-less bike-sharing systems. This study examines the emergence, rapid growth and consolidation of station-less bike-sharing systems and the role of suppliers, users and government regulators. It shows that these systems developed unevenly, growing most in large cities in eastern and south-eastern China, and explores the relationship between this spatial distribution and the nature of the service and the socio-economic characteristics of cities. To investigate patterns of, and reasons for, the use of these systems, this research also reports the results of a survey of users and non-users, identifying their gender, age, income characteristics and attitudes to station-less systems.

The recent literature on the “consumer city” and the “love of variety” argues that the provision of urban amenities makes a city more attractive. Meanwhile, polycentric urban development has been highlighted by academics and policymakers as a sustainable urban development regime, although its purported benefits need to be further investigated. Against this background, this paper empirically examines the relationship between polycentricity and the provision of urban amenities in 309 Chinese cities. After controlling for the size, population density, wage, and human capital, this paper finds that a higher degree of intra-urban polycentricity is associated with a larger number of urban amenities. Additionally, when all the covariates above are held, a higher degree of intra-urban polycentricity is associated with a greater diversity of urban amenities. Robust checks show that these findings are consistent with different polycentricity indices and diversity measures. Finally, possible explanations of the relationship between intra-urban polycentricity and urban amenities are provided from both the producer and consumer perspectives.

At present, rail transit in China is booming. At the same time, some big cities are undergoing a crucial stage of adjustment of urban spatial structure. Therefore, it is significant to study the relationship between the development of rail transit and the evolution of urban spatial structure. This paper reviews the development of Guangzhou rail transit and the evolution of Guangzhou urban spatial structure, and discusses the relationship between them. The conclusion is that there is interactive relationship between the development of rail transit and the evolution of urban spatial structure, and the construction and planning of rail transit should coordinate with the current condition and future planning of urban spatial structure. During network planning, the focus should not only be placed on the rail transit project itself, but the construction of a scientific and reasonable urban spatial structure, so that rail transit can contribute to sustainable urban development.

This paper presents an original attempt to bring forward extended perspectives about the City Classification System (CCS) in Vietnam. For many years, the CCS has played a central role the development of Vietnam national urban system as well as a motivating guideline for individual cities. However, (1) aspects of sustainable urban development are underrepresented among the CCS indicators and (2) the CCS remains a top-down, rigid policy which takes away much of the local development context and their developmental challenges. It is argued that Vietnam CCS needs adjusting to better reflect the multi-dimensional nature of urban development process (especially sustainability) and to better comprehend people-oriented, local development.
