Executive summary

A major flood of the Seine River, similar to the historic event of 1910, is an important challenge for public policy. The economic, social and human issues at stake are considerable, given the large scale and high vulnerability of the floodplain and because the Paris – Île-de-France region is the principal economic hub in France. Over the last decade, many countries have experienced floods beyond historic records (Prague in 2002, the United Kingdom in 2007, Australia in 2011, Bangkok in 2011, New York in 2012, Germany in 2013). At the same time, vulnerabilities of modern societies and megacities in particular have steadily increased, calling for considering this major risk and its implications in all its multiple dimensions. As the economic impact of a major Seine flood could be significant on national output, it appears important to question the level of protection and the resilience of the Paris metropolitan area with an international perspective. This calls for a collective and voluntary reflexion on flood risk management policies in the Ile-de-France region.
