This research leverages open-source tools (PostGIS, pgRouting) to assess indirect flood risks—power outages and road isolation—for businesses in England and Wales that are not directly at risk of flooding. It supports Rebalance Earth’s sustainable investment strategy by revealing overlooked secondary impacts of flooding.
Flooding threatens millions of UK businesses. While direct damage is well studied, the hidden secondary risks—like power outages and road closures—are often overlooked. This talk introduces a decision-support analytical framework that maps these indirect impacts, helping Rebalance Earth target businesses outside flood zones for their investment strategies.
Built with open-source tools like PostGIS, pgRouting, and QGIS, the framework works at two levels:
AOI-wide: Pick any region in England to see businesses at risk of losing power (via flooded substations) or being cut off (via road disruption).
Business-specific: Estimate added travel time on roadways under given flood scenarios.
By integrating flood data with power networks and road systems, this tool highlights risks that many businesses—and investors—don’t yet see. It’s a scalable approach to strengthening resilience where it matters most.
