ABSTRACT New challenges in the efficient management of cities depend on a deep knowledge of their inner structures. It is therefore very important to have access to reliable models of cities characteristics and organization. This paper aims at providing and validating a stochastic modelization based on statistical data of buildings parameters which can be useful as an entry for many other model...

The continuing debate on a new urban agenda in Canada has largely focused on the striking imbalance between the revenue sources and service responsibilities of cities and other local municipalities. Newspaper stories and images abound of decaying infrastructure, under-funded transit, housing shortages, rising deficits, and concentrated poverty. The recent Speech from the Throne of the new feder...

T he last century has witnessed the fastest population growth in human history, with the result that, for the first time, more than 50% of the world population lives in cities. This process is still advancing. According to United Nations predictions, urban population will exceed 75% of the world’s population by 2070. Furthermore, estimates are that if the current trends continue, by the end of ...

With the rise of interest in urban sustainability, the question of nature is front and center. This review suggests bridging between three distinct research paths concerned with urban areas and nature: urban ecosystem services, urban metabolism and urban political ecology to forge new thinking to transition from the sanitary city of the twentieth century to the sustainable city of the twenty-fi...

The historic cities of Brazil, despite its colonial structure, don't fail to go through transformations that affect contemporary cities, which is the main source of problems, leading to new approaches to urban issues such as mobility and accessibility. The uncontrolled growth of tourism in the historic cities can be considered as a big problem, because at the same time, they have committed to t...

Residential segregation is defined in a variety of ways to address a common concern: to what extent do social groups reside in separate or distinct places. The spatial pattern of segregation varies widely across cities, and distinct spatial patterns can be generated by different mechanisms and have different consequences for residents and their communities. However, the methods commonly employe...

Asian immigrants to the U.S. are settling in "new destinations," but there has been little research on their health care and social service needs. Our analysis of Census data to identify cities with the fastest Asian immigrant population growth (1990-2000) yielded 33 smaller cities in 13 states. The cities ranged in population from 7,677 to 86,660; were spread across 13 states in the Northeast,...

Understanding and transforming how cities think is a crucial part of developing effective knowledge infrastructures for the Anthropocene. In this article, we review knowledge co-production as a popular approach in environmental and sustainability science communities to the generation of useable knowledge for sustainability and resilience. We present knowledge systems analysis as a conceptual an...

Global Cities are characterised by their dominance in world affairs, linked to population size and political, economic, social and cultural infrastructure. As urban centres expand, particularly in the developing regions of the South, a new generation of Global Cities seems likely to emerge. Indeed, non-Western Global Cities have already emerged in some Asian (e.g. Hong Kong, Singapore) and Lati...

We propose a quantitative method to classify cities according to their street pattern. We use the conditional probability distribution of shape factor of blocks with a given area and define what could constitute the 'fingerprint' of a city. Using a simple hierarchical clustering method, these fingerprints can then serve as a basis for a typology of cities. We apply this method to a set of 131 c...
