Environmental Factor – May 2021: Geospatial technology for environmental health
Remote geospatial technology generates data that offer precision insights to environmental health scientists and decisionmakers. The experts who gathered for the latest workshop by the National Academies of Science, Engineering, and Medicine (NASEM) discussed how geospatial data may improve exposure estimates. The April 14-15 meeting, co-sponsored by NIEHS, connected those who produce geospatial data with users of their output.
“Place really matters for health,” said Susan Anenberg, Ph.D., from The George Washington University (GWU). Anenberg chaired the workshop’s organizing committee.
NIEHS and National Toxicology Program Director Rick Woychik, Ph.D., gave opening remarks. He described the enormous challenges involved in estimating the exposome, or the sum of all exposures a person experiences across the life span. “It’s becoming clear that geospatial information can provide a powerful enhancement to the way that we collect environmental exposure data,” he said.
More than pollution, genetics
As several of the speakers highlighted, health is more than just pollution and genetics. Anenberg noted that geospatial technologies open new avenues in environmental health, from novel epidemiological approaches to forecasting extreme weather.
- The distribution of pollution levels and vulnerability in the underlying population influence environmental health inequities.
- Advances in remote sensing and personal monitors of environmental conditions and behavior take exposure science down to the individual level.
- Electronic health records expand the amount and type of anonymized health data available for environmental health studies.
- Satellite data and geospatial models can help communities prepare for and respond to extreme weather and other disasters.
The confluence of heightened awareness about environmental health risks and environmental injustice, coupled with widening availability of different types of remote geospatial technologies, make this the right time to foster the transdisciplinary collaborations needed to make the best use of geospatial data, Anenberg said.
Equity moves to forefront
Organizers invited two keynote speakers. Cecilia Martinez, Ph.D., the White House Council on Environmental Quality senior director for environmental justice, discussed a new program called the Justice40 Initiative. The government-wide effort aims to deliver 40% of the overall benefits of federal investment in clean energy to disadvantaged communities.
“Equity and justice, as part of climate and energy, is a relatively immature field,” she said. “My role is to make sure equity is front and center … in decision-making tools and in the data portals.” She further stressed the importance of community engagement and building trust between scientists, government representatives, and community members.
Spatial patterns matter
Keynote speaker Marie Lynn Miranda, Ph.D., from the University of Notre Dame, focused on four concepts.
- Health is spatially patterned, in terms of trends, disease statistics, and other health indicators.
- Contributions to health — such as green space, industrial exposures, water quality, and access to fresh food — are spatially patterned.
- Health care access — how far is the nearest dentist or mental health professional? — is…
