CPEP Seminar – Uncovering the Hidden Health Costs of Flooding from Space: New Insights from Satellite Data and Machine Learning

Speaker: Jonathan Sullivan, Assistant Professor, Nelson Institute for Environmental Studies, UW–Madison

Globally, flooding affects more people than any other environmental hazard and their consequences are far from uniform, often exacerbating existing social and economic vulnerabilities. The escalating severity of heavy precipitation has the potential to amplify the disproportionate effects of flooding on vulnerable populations. In particular, flooding is known to affect numerous health outcomes including infectious disease, mental health, and access to healthcare.

However, previous investigations on flood damage and loss have been limited to a handful of health outcomes, localized case studies, and rarely attending to the disproportionate burden experienced by vulnerable communities. The lack of empirical evidence is, in part, due to inconsistent and sparse records of historical flood exposure.

This talk will explore how novel methods to characterize flood exposure with satellite imagery and machine learning can enable empirical analyses of flood-related health outcomes across large spatio-temporal scales. Example studies from the United States and Bangladesh will demonstrate how such methods can work in data rich and sparse contexts. This work provides insight into how flooding can influence health over longer time horizons than previously studied while also identifying underlying factors that predispose communities to loss.

This seminar can also be viewed via our live stream.
