With natural disasters become more frequent and damaging, how can we accurately access who's at risk without updated information and predictions? The answer is we can't. That's why accurate risk and hazard mapping is essential for both private homeowners and all levels of government that have a public responsibility to mitigate the adverse after-effects of disasters. In this episode we talk to Professor Joseph Desloges of the Geography and Planning Department at the University of Toronto. He specializes in the influence of rivers, glaciers and humans on landform development, and has a particular interest in flood risk mapping. We discuss topics like accurate risk assessment, geoengineering solutions to floods, and what have been the key human-driven changes that have left our cities exposed to flood-related damages.
