Paris faces several urban challenges as it transforms due to metropolization, including air pollution, flooding risks, traffic issues, and food supply concerns. Air pollution causes 48,000 premature deaths per year and risks to public health. Flooding of the Seine River could cause billions in damages by disrupting transportation, utilities, and business activity. The city also struggles with how to increase sustainable local food production as the population grows. Comprehensive strategies are needed to address these interconnected issues affecting Paris' environment, economy, and livability.

11. Impact of major flood in critical networks
❏ The distribution of electricity could be largely affected with almost one quarter of
power sub-stations flooded or cut off as a precaution and more than 1.5 million
customers who could experience power cuts.
❏ Public transport could be affected with almost 140 km of the 250 km underground
network closed as a precaution. The road network could be blocked at many points.
❏ The drinking water supply could be interrupted around Paris where more than 5
million clients could suffer extended water cuts and 1.3 million a deterioration in
quality.
❏ According to flood scenarios, the damage from such a catastrophe has been
estimated to be between 3 to 30 billion euros for direct damage, together with a
significant reduction in GDP which, over five years, could reach 1.5 to 58.5 billion
euros, i.e. a consolidated total of 0.1 to 3%.

13. ❏ The resulting contraction in business activity could have a significant effect on the
demand for labour; up to 400,000 jobs could be lost in the worst case scenario.
❏ Even if a rebound in business activity could rapidly reduce some of these effects
after a year, the harmful consequences of a major Seine flood could be felt over the
medium to long term and weigh on public finances.
