Global sustainability relies on our capacity of understanding and guiding urban systems and their metabolism adequately. It has been proposed that bigger and denser cities are more resource-efficient than smaller ones because they tend to demand less infrastructure, consume less fuel for transportation and less energy for cooling/heating in per cap...
[This corrects the article DOI: 10.1371/journal.pone.0233003.].
Does the scaling relationship between population sizes of cities with urban metrics like economic output and infrastructure (transversal scaling) mirror the evolution of individual cities in time (longitudinal scaling)? The answer to this question has important policy implications, but the lack of suitable data has so far hindered rigorous empirica...

Global sustainability relies on our capacity of understanding and guiding urban systems, and their metabolism, in an adequate way. It has been proposed that bigger and denser cities are more resource-efficient than smaller ones because they tend to demand less infrastructure, consume less fuel for transportation and less energy for cooling or heati...
Given that a group of cities follows a scaling law connecting urban population with socio-economic or infrastructural metrics (transversal scaling), should we expect that each city would follow the same behavior over time (longitudinal scaling)? This assumption has important policy implications, although rigorous empirical tests have been so far hi...
It is clear by now that climate change mitigation relies on our capacity to guide urban systems towards a low-carbon phase and that the urban transportation sector plays a major role in this transition. It is estimated that around 30% of total CO2 emissions worldwide come from the urban transportation sector. Regardless of its importance, detailed...
Hosting more than half of the world population, cities are currently responsible for two thirds of the global energy use and three quarters of the global CO2 emissions related to energy use. As humanity becomes more urbanized, urban systems are becoming a major nexus of global sustainability. Various studies have tried to pinpoint urban energy use...
From physics to the social sciences, information is now seen as a fundamental component of reality. However, a form of information seems still underestimated, perhaps precisely because it is so pervasive that we take it for granted: the information encoded in the very environment we live in. We still do not fully understand how information takes th...

During the last years, the new science of cities has been established as a fertile quantitative approach to systematically understand the urban phenomena. One of its main pillars is the proposition that urban systems display universal scaling behavior regarding socioeconomic, infrastructural and individual basic services variables. This paper discu...
Deviations from the expected scaling regime proposed by Bettencourt [10] for all the statistically significant variables.
Values for β, and its 95% confidence interval refers to the final density cut-off value. Statistically insignificant variables are not presented.

Exponents values for different urban indicators in the Brazilian urban system.
Each dot represents the scaling exponent related to the best-fit line from the OLS regression of the population against the studied variable; vertical line segments represent 95% confidence interval (CI) of those regressions; colors are based on the proposed regime; the...
Scaling exponent β as a function of minimum density cut-off for all the variables.
Each line represents the scaling exponent (y-axis) from OLS regressions of the log-transformed data of each variable as a function of the minimum density cut-off (x-axis).

Resumo Como ações pessoais, aparentemente caóticas, podem gerar os imensos sistemas de interações em que vivemos? Neste artigo, buscamos responder a esta pergunta sugerindo que há um papel para as cidades, na forma de coordenar nossas ações. Investigamos esse processo explorando um conceito particular: a “entropia” ou como sistemas lidam com a ince...
Integrating social and spatial networks will be critical to new approaches to cities as systems of interaction. In this paper, we focus on the spatial and temporal conditions of encounters as a key condition for the formation of social networks. Drawing on classic approaches such as Freeman’s concept of segregation as ‘restriction on contact’, Häge...

Cities are responsible for the predominant share of anthropogenic environmental pressures. Recently, consistent methodologies to measure the metabolism of cities have been developed in order to enhance comparability between case studies and enable cross-city comparisons at the macro-scale. This comparison illustrated potential factors and drivers e...
How can individual acts amount to coherent systems of interaction? In this paper, we attempt to answer this key question by suggesting that there is a place for cities in the way we coordinate seemingly chaotic decisions. We look into the elementary processes of social interaction exploring a particular concept, “social entropy,” or how social syst...
Integrating social and spatial networks will be critical to new approaches to cities as material systems of interaction. In this paper, we propose a way of doing so by focusing on the spatial and temporal conditions of formation of social networks – namely, on 'encounters' as a key social event. Drawing on classic approaches such as Freeman's conce...
Socioeconomic related properties of a city grow faster than a linear relationship with the population, in a log–log plot, the so-called superlinear scaling. Conversely, the larger a city, the more efficient it is in the use of its infrastructure, leading to a sublinear scaling on these variables. In this work, we addressed a simple explanation for...

From a tradition that can be traced back to the Chicago School, social segregation has been mostly seen as the natural consequence of the social division of space, taking the space as a surrogate for social isolation. We propose a change in the focus from static segregation of places to how social segregation is performed in embodied urban trajecto...
Segregation has been one of the most persistent features of cities and therefore one of the main research topics in social studies. From a tradition that can be traced back to the Chicago School in the early 20th century, social segregation has been seen as the natural consequence of the social division of space, reducing segregation territorial se...
