Constructing Valid Geospatial Tools for Environmental Justice: New Report

Decades of research have shown that the most disadvantaged communities exist at the intersection of high levels of hazard exposure, racial and ethnic marginalization, and poverty. Geospatial environmental justice (EJ) tools, such as the White House Council on Environmental Quality-developed Climate and Economic Justice Screening Tool (CEJST), are designed to integrate different kinds of health, social, environmental, and economic data to identify disadvantaged communities and to aid policy and investment decisions that address the pervasive, persistent, and largely unaddressed problems associated with environmental disparities in the United States.  Constructing Valid Geospatial Tools for Environmental Justice, a new report from the National Academies of Sciences, Engineering, and Medicine, offers recommendations for developing environmental justice tools that reflect the experiences of the communities they measure.

I am very proud to co-chair this consensus study committee and grateful to work with an excellent study committee and the first-rate National Academies staff on a report that I sincerely hope leads to environmental justice for all in the US.

I had the honor of giving the E. Willard and Ruby S. Miller Endowed Lecture in the Department of Geography at Pennsylvania State University on March 15, 2024. My talk was titled “Mapping Columbus’ Ghost Neighborhoods: Using AI and GIS to Create 3D Models of Neighborhoods Damaged by Urban Highways and Urban Renewal in the 20th Century.”

Measuring just accessibility within planetary boundaries

New paper: Willberg, E., Tenkanen, H., Miller, H.J., Pereira, R. H. M. and Toivonen, T. (2023) “Measuring just accessibility within planetary boundaries,” Transport Reviews, DOI: 10.1080/01441647.2023.2240958.

Abstract. Our societies struggle to provide a good life for all without overconsuming environmental resources. Consequently, scholarly search for approaches to meet environmental and social goals of sustainability have become popular. In transport research, accessibility is a key tool to characterise linkages between people, transport, and land use. In the current paper, we propose a conceptual framework for measuring just accessibility within planetary boundaries. We reviewed transport studies and discovered a substantial literature body on accessibility and social disadvantage, much vaster compared to the literature around environmental and ecological impacts of accessibility. We also show a gap in approaches that have integrated these two perspectives. Building on the review, we suggest a conceptual framework for incorporating environmental and social sustainability goals in accessibility research. We conclude the paper by pointing to key challenges and research avenues related to the framework, including (i) dealing with uncertainty and complexity in socio-ecological thresholds, (ii) integrating environmental limits into the conceptualisations of transport equity, (iii) measuring accessibility through other costs than travel time, and (iv) integrating both quantitative and qualitative data.
