Chapter
United Nations Sustainable Development Goal 11, “Sustainable Cities and Communities,” makes information about cities’ areas, their populations, and their change over time, essential inputs to the goal's reporting requirements. The key charge of indicator 11.3.1 is to measure change in land consumption per capita over time in cities, to understand w...
Article
The findings introduced in this longitudinal study of cumulative Covid-19 cases and deaths are based on reported data for 384 US Metropolitan Statistical Areas (MSAs) for 20 weeks, starting on March 6, 2020 and ending on July 23, 2020. We look at the variation in the 7-day averages of the cumulative numbers of reported cases and deaths in each city...

Serious concerns with accelerating global warming have been translated into urgent calls for increasing urban densities: higher densities are associated with lower greenhouse gas emissions, especially those related to vehicle kilometers traveled (VKT). In order to densify meaningfully in the coming decades, cities need to make room within their exi...
Article
Full-text available
Serious concerns about global warming have been translated into urgent calls for increasing urban densities, as higher densities are associated with lower carbon emissions from both vehicles and buildings. However, attempts at effective densification have generally failed and urban densities continue to decline in cities across the world. Calls for...

We introduce evidence from the Covid-19 pandemic in the United States that lends support to future political efforts to include multi-county metropolitan areas as an additional and critical institutional layer—over and above municipalities, countries, states, or the federal government—for the effective management of present and future pandemics. Mu...
Article
In this paper, we examine the relationship between built-up area residential density and organized violence. Security for most of human history has been one of the driving factors for city development and growth; this remains true today. What is new, is that the prevalence of organized violence is associated with increased population density in adj...
Article
Urban population density has featured in a large body of literature on the Compact City paradigm as the key compactness attribute of cities, yet the shape compactness of urban footprints has hardly deserved a mention. This essay seeks to correct that. We review the literature on the Compact City Paradigm with a special focus on the relationship bet...
Article
Recent research indicates that a simplified approach to urban planning in Sub-Saharan African cities can address the challenges of rapid urban growth. Current plans focus too heavily on the existing area of the city and offer unrealistic agendas for future urban growth, such as densification, containment and high-rise development; plans that are of...

The commentary reflects on the critical ways in which the proliferation of private property rights and local planning powers constrain and delimit the changes in the forms of cities that will be required in the coming years to ensure that they remain productive, inclusive, and sustainable. It argues that the effective management of the coming disru...

Urban transport and land use policies are informed by our perceptions of the prevailing spatial structure of cities. This structure can be characterized by five models: The Maximum Disorder model, the Mosaic of Live-Work Communities model, the Monocentric City model, the Polycentric City model, and the Constrained Dispersal model, where the great m...

Full-text available
The greatest productive advantage of modern-day American cities is that they form large and integrated metropolitan labor markets. We present new evidence on the importance of self-adjusting commuting and location patterns in sustaining the productive advantages of larger metropolitan labor markets, mitigating the difficulties in coping with their...

The fragmentation of urban landscapes – or the inter-penetration of the built-up areas of cities and the open spaces in and around them – is a key attribute of their spatial structure. Analyzing satellite images for 1990 and 2000 for a global sample of 120 cities, we find that cities typically contain or disturb vast quantities of open spaces equal...
Article
Our study of the expansion of a representative sample of 30 cities showed that 28 of them expanded more than 16-fold during the twentieth century. More generally, cities are now expanding at twice their population growth rates, on average, and now cover almost 0.5% of the planet's land area. We created a new dataset comprising the universe of all 3...

The policy focus report series is published by the Lincoln Institute of Land Policy to address timely public policy issues relating to land use, land markets, and property taxation. Each report is designed to bridge the gap between theory and practice by combining research findings, case studies, and contributions from scholars in a variety of acad...
Article
This essay sheds new light on the meaning and measurement of compactness—one of the most intriguing and least-understood properties of geographic shapes. We articulate a unified theoretical foundation for the study of shape compactness that rests on two simple observations: First, that the circle is the most compact of shapes. And second, that ther...

Eight groups from government and academia have created 10 global maps that offer a ca 2000 portrait of land in urban use. Our initial investigation found that their estimates of the total amount of urban land differ by as much as an order of magnitude (0.27–3.52 ×10 km). Since it is not possible for these heterogeneous maps to all represent urban a...
Article
Between 2000 and 2030, cities in developing countries will double their population from 2 to 4 billion and at least triple their total built-up area. This essay assesses the state of preparedness for the projected urban expansion. The available anecdotal evidence suggests that areas needed for expansion are typically underestimated, that enforcemen...
Article
This paper discusses strategies for the development of water resources, emphasizing the delivery of reliable water supplies, for both domestic and production purposes, to every village and to every farmer. This necessitates a shift of emphasis from the construction of large storage reservoirs to the construction, operation, and maintenance of water...
Article
This note uses available research and global population data to show that over time the share of the urban population inhabiting the centre has declined relative to the urban population of the periphery. The decline of the population of the centre is measured on global, national, and metropolitan scales: (1) as the declining share of the global urb...

We define and present a comprehensive set of metrics for five dynamic attributes of urban spatial structure commonly associated with 'sprawl': (a) the extension of the area of cities beyond the walkable range and the emergence of 'endless' cities; (b) the persistent decline in urban densities and the increasing consumption of land resources by urba...
Article
The aim of this paper is to help project teams develop results indicators for housing projects. These indicators are intended, primarily, as an instrument for managing projects and should help staff in the country offices, in headquarters and in executing agencies to identify the components of a project that are working as intended, and the ones th...

This study examined the dynamics of global urban expansion by defining a new universe of 3,943 cities with population in excess of 100,000 and drawing a stratified global sample of 120 cities from this universe. Population data and satellite images for two time periods⎯a decade apart⎯were obtained and analyzed, and several measures of urban extent...
Article
This paper presents a diagnostic tool for the rapid assessment of the housing market and housing policy in a given country, using a global comparative perspective. The aim of such an assessment is to ground proposed government interventions in the housing market in a broader housing market reform. The rapid assessment requires defining the critical...
Article
The private sector in Thailand moved into construction of housing for low-income people in 1986, initiating at least 37 new projects which offered housing at prices ranging from 150 000 to 250 000 Baht. A sales office survey was conducted in all these projects, as part of the Bangkok Land Management Study. A comparison of rates of sale shows that l...
Article
Approximately one-third of Bangkok households rented their accommodation during the 1970s, and this proportion was slowly decreasing by 1981. Most rental housing is in row houses, but the proportion of apartments is increasing. Construction materials are evenly divided between concrete and brick on the one hand and wood on the other. A general inve...
Article
This paper centres on the development of a geometrical representation of movement and spatial interaction in urban areas, as distinct from the network representation commonly used in modern studies. All quantities are treated as distributions over geographic space, rather than concentrations at nodes of a network. We present a continuous model of s...
Article
The city is not an undifferentiated terrain and travel does not occur along straight-line paths at constant velocities. Variations in travel velocities at different locations bend the minimum time paths away from regions of high congestion. This paper discusses a transformation of the urban plane into a time surface on which distance corresponds to...
Article
Procedures are overviewed and preliminary results are presented for a project addressing urban growth mapping for a sample of 120 metropolitan areas from a universe of 2,719 cities having populations in excess of 100,000 in the year 2000. A modified unsupervised classification approach applied to Landsat imagery serves as the basis for urban cover...
