Equity in the Built Environment

I coauthored a recently published article in Building and Environment which systematically reviews perspectives on and approaches to social equity in the built environment. From the abstract:

Equity in the built environment refers to the extent to which the built environment meets the needs of different groups through planning, design, construction, operation, management, and regulation. Though much studied in recent years, some needs and groups have received a greater research focus than others, and significant inequities continue to exist. Following PRISMA guidelines, we systematically reviewed the distributional and recognitional aspects of inequities experienced by vulnerable groups regarding their needs while using/occupying different types of built environments. We find that more studies focus on inequities regarding residential buildings, transportation facilities, and public open spaces, whereas comparatively few studies examine water and energy infrastructure, commercial buildings, educational buildings, and healthcare facilities. More studies focus on well-being, mobility, and access needs than shelter and safety needs. Inequities experienced by minorities, people with low socioeconomic status, people with health concerns, and vulnerable age groups receive more attention than the inequities experienced by people with gender/sexual-orientation vulnerability or displaced groups. The literature exhibits a relatively narrow focus on some subgroups, such as refugees, people experiencing homelessness, people with cognitive differences, people with visual or hearing impairments, children, and women. We argue that these findings demarcate high-impact future research directions to address vulnerable groups’ needs worldwide and suggest measures to alleviate inequities in the built environment.

Delivering Healthy and Sustainable Cities

I have a new article out now in The Journal of City Climate Policy and Economy, coauthored with a team that includes several of the folks from our recent series in The Lancet Global Health. The JCCPE article, “A Pathway to Prioritizing and Delivering Healthy and Sustainable Cities,” synthesizes findings and recommended policy actions arising from that recent TLGH series.

From the abstract:

Creating healthy and sustainable cities should be a global priority. Some cities prioritize 15-minute cities as a planning approach with co-benefits for health, climate change mitigation, equity, and economic recovery from COVID-19. Yet, as our recent The Lancet Global Health series on “Urban Design, Transport, and Health” showed, many cities have a long way to go to achieve this vision. This policy guideline summarizes the main findings of the series, which assessed health and sustainability indicators for 25 cities in 19 countries. We then outline steps governments can take to strengthen policy frameworks and deliver more healthy, equitable, and sustainable built environments. The Lancet Global Health series provided clear evidence that cities need to transform urban governance to enable integrated planning for health and sustainability and commit to policy implementation. Evidence-informed indicators should be used to benchmark and monitor progress. Cities need policy frameworks that are comprehensive and consistent with evidence, with measurable policy targets to support implementation and accountability. The series provided evidence-informed thresholds for some key urban design and transport features, which can be embedded as policy targets. Policies and interventions must prioritize identifying and reducing inequities in access to health-supportive environments. Governments should also invest in open data and promote citizen-science programmes, to support indicator development and research for public benefit. We provide tools to replicate our indicators and an invitation to join our 1,000 Cities Challenge via the Global Observatory of Healthy and Sustainable Cities.

ISPAH in Abu Dhabi

Alongside Billie Giles-Corti and Jim Sallis, I will be presenting our team’s recent research into accessible, sustainable urban design around the world at the ISPAH Congress in Abu Dhabi this week. Our symposium at the congress will share the methods and findings from our The Lancet Global Health series published this summer, as well as our ongoing work on the Thousand Cities Challenge.

Our geospatial team developed open-source software to calculate indicators of walkability and accessibility around the world, and then linked these back to cities’ policy contexts and identified populations living above and below estimated thresholds for physical activity. Few cities had measurable policy standards and targets to actually build healthier and more sustainable cities, and their health-supportive built environment features were often inadequate or inequitably distributed.

We simultaneously launched the Global Observatory of Healthy and Sustainable Cities to promote healthy and sustainable urban planning, benchmark and monitor cities’ progress, and share more consistent, comparable urban data. The whole series of articles is free and open access, as is our software.

New Article: Complexity in Urban Form and Design

My article, Measuring the Complexity of Urban Form and Design, is now in-press for publication at Urban Design International (download free PDF). Cities are complex systems composed of many human agents interacting in physical urban space. This paper develops a typology of measures and indicators for assessing the physical complexity of the built environment at the scale of urban design. It extends quantitative measures from city planning, network science, ecosystems studies, fractal geometry, statistical physics, and information theory to the analysis of urban form and qualitative human experience.
