Flood Risk Index

Flooding is the most pervasive among natural disasters, yet its costs are routinely underestimated. As climate change, economic and demographic trends, and a chronic lack of investments in resilience combine to drive risk higher, it is time to rethink our approach to flood risk.

Rethinking Flood is a series of publications examining the implications of flooding for corporates, governments, and society. It is accompanied by the open-source Marsh McLennan Flood Risk Index, which leverages research from international organizations and academic institutions to provide a global overview of flood risk and its potential implications on human and economic systems under different climate change scenarios. To help develop flood risk management strategies and increase the resilience of assets and populations a range of tailored tools and solutions are available from across Marsh McLennan.

Sunk Costs: The Socioeconomic Impacts of Flooding is the first report in the series, analyzing the current state of flood risk globally, its economic and societal consequences, and the role of insurance in protecting the most vulnerable.

Preparing for a Wetter World: Strategies for Corporate Flood Resilience explores the implications of flood risk for businesses and discusses how firms can reimagine their approach to flood risk management in the context of climate change, growing business complexity, and stakeholder management.

Staying above water: A systemic response to rising flood risk outlines critical points of failure in current flood risk management systems and describes a clear vision for flood resilience revolving around three interdependent ways forward: Living with floods, building strategic protection, and preparing for relocation.
