Multilevel comparison of large urban systems

For the first time the systems of cities in seven countries or regions among the largest in the world (China, India, Brazil, Europe, the Former Soviet Union (FSU), the United States and South Africa) are made comparable through the building of spatio-temporal standardised statistical databases. We first explain the concept of a generic evolutionary urban unit ("city") and its necessary adaptations to the information provided by each national statistical system. Second, the hierarchical structure and the urban growth process are compared at macro-scale for the seven countries with reference to Zipf's and Gibrat's model: in agreement with an evolutionary theory of urban systems, large similarities shape the hierarchical structure and growth processes in BRICS countries as well as in Europe and United States, despite their positions at different stages in the urban transition that explain some structural peculiarities. Third, the individual trajectories of some 10,000 cities are mapped at micro-scale following a cluster analysis of their evolution over the last fifty years. A few common principles extracted from the evolutionary theory of urban systems can explain the diversity of these trajectories, including a specific pattern in their geographical repartition in the Chinese case. We conclude that the observations at macro-level when summarized as stylised facts can help in designing simulation models of urban systems whereas the urban trajectories identified at micro-level are consistent enough for constituting the basis of plausible future population projections.Comment: 14 pages, 9 figures; Pumain, Denise, et al.

Probing the position of the Jakarta metropolitan area in global inter-urban networks through the lens of manufacturing firms

This paper presents an analysis of the position of the Jakarta metropolitan area (JMA) in global inter-urban networks. Our starting point is our aim to provide a more nuanced understanding of the JMA’s connectivity in world city networks (WCNs). To this end, we steer clear of top-down approaches, which tend to analyze cities in singular taxonomies of global prominence, and instead propose a framework that is attuned to the JMA’s contexts to provide an alternative and complementary reading of how the JMA has been inserted into the WCN. To this end, by drawing on the interlocking network model, which helps to proxy inter-urban networks based on the multi-locational operations of manufacturing firms, we examine the JMA’s network positionality on the global and national scales. The results provide evidence of the JMA’s global inter-city relations being strongly geared toward East Asian cities. In addition, the results suggest that the JMA cannot be detached from its national geography, as evidenced by its strong connections with cities located on the island of Java

Dynamic multi-dimensional scaling of 30+ year evolution of Chinese urban systems: patterns and performance

Understanding the co-evolution and organizational dynamics of urban properties (i.e., urban scaling) is the science base for pursuing synergies toward sustainable cities and society. The generalization of urban scaling theory yet requires more studies from various developmental regimes and across time. Here, we extend the universality proposition by exploring the evolution of longitudinal and transversal scaling of Chinese urban attributes between 1987 and 2018 using a global artificial impervious area (GAIA) remotely sensed dataset, harmonized night light data (NTL), and socioeconomic data, and revealed agreements and disagreements with theories. The superlinear relationship of urban area and population often considered as an indicator of wasting land resources (challenging the universality theory β  = 2/3), is in fact the powerful impetus (capital raising) behind the concurrent superlinear expansion of socio-economic metabolisms (e.g., GDP, total wage) in a rapidly urbanizing country that has not yet reached equilibrium. Similarly, infrastructural variables associated with public services, such as hospitals and educational institutions, exhibited some deviations as well and were scaled linearly. However, the temporal narrowing of spatial deviations, such as the decline in urban land diseconomies of scale and the stabilization of economic output, clearly indicates the Chinese government's effort in charting urban systems toward balanced and sustainable development across the country. More importantly, the transversal sublinear scaling of areal-based socio-economic variables was inconsistent with the theoretical concept of increasing returns to scale, thus validating the view that a single measurement cannot unravel the intricate web of diverse urban attributes and urbanization. Our dynamic urban scaling analysis across space and through time in China provides new insights into the evolving nexus of urbanization, socioeconomic development, and national policies

Uneven and combined development: modernity, modernism, revolution

Trotsky’s theory of Uneven and Combined Development was born out of his experience of the Russian Revolution. To mark the centenary of the revolution, we are publishing a series of five pieces by Neil Davidson that explore the theory’s wider contribution to how we understand capitalist modernity. These articles show how ideas that began life in the revolution continue to inspire new ways of grasping the world, and that we are very much engaging in a living 21st century world when reflecting on the previous century. The series published here are extracts of his forthcoming book Violating all the Laws of History that will be published in the Haymarket Historical Materialism series in 2018

New Global Cities in Latin America and Asia

New Global Cities in Latin America and Asia: Welcome to the Twenty-First Century proposes new visions of global cities and regions historically considered “secondary” in the international context. The arguments are not only based on material progress made by these metropolises, but also on the growing social difficulties experienced (e.g., organized crime, drug trafficking, slums, economic inequalities). The book illustrates the growth of cities according to these problems arising from the modernity of the new century, comparing Latin American and Asian cities. This book analyzes the complex relationships within cities through an interdisciplinary approach, complementing other research and challenging orthodox views on global cities. At the same time, the book provides new theoretical and methodological tools to understand the progress of “Third World” cities and the way of understanding “globality” in the 21st century by confronting the traditional views with which global cities were appreciated since the 1980s. Pablo Baisotti brings together researchers from various fields who provide new interpretative keys to certain cities in Latin America and Asia

The Critical Role of Public Charging Infrastructure

Editors: Peter Fox-Penner, PhD, Z. Justin Ren, PhD, David O. JermainA decade after the launch of the contemporary global electric vehicle (EV) market, most cities face a major challenge preparing for rising EV demand. Some cities, and the leaders who shape them, are meeting and even leading demand for EV infrastructure. This book aggregates deep, groundbreaking research in the areas of urban EV deployment for city managers, private developers, urban planners, and utilities who want to understand and lead change
