Challenges for ci4es • Fast urbaniza4on process especially in developing countries • Land use compe44on (less space for water …) • Increase of value (goods) • Climate evolu4on • Difficulty to integrate “dynamic standards” • Increase of vulnerability • Acceptability of level of risk • Need for developing resilience strategie for the “City system”

What is a city? Func4onal analysis / Systemic analysis / Holis4c approach Services provided to popula4on (spa4al extend):
• Housing • Work • Safety • Health • Educa4on • Leisure • Religion
University of Nice – Sophia Antipolis / Polytech’Nice-Sophia
What is a city? Few support func4ons:
• Energy • Water • Food • Waste • Transport
… Networks which have a growing inter-‐connec4vity
University of Nice – Sophia Antipolis / Polytech’Nice-Sophia
What is a city? Services and func4ons are covering various spa4al scales Evalua4on made according the 4 basic components:
• parcel / building • block • district • city
University of Nice – Sophia Antipolis / Polytech’Nice-Sophia
Challenge for the ci4es • How the system is affected by flooding ? • Which services & func4ons are affected? • What are priori4es for popula4on? • What is the level of risk acceptability? • Most efficient ac4ons according to targets & evolu4on? • Which strategy for resilience?
University of Nice – Sophia Antipolis / Polytech’Nice-Sophia
Type of flooding • Rivers • Groundwater • Coastal • Pluvial flooding
• Characteris4cs & consequences are linked to topography / morphology

Challenge for the ci4es • How the system is affected by flooding ? • Which services & func4ons are affected? • What are priori4es for popula4on? • What is the level of risk acceptability? • Most efficient ac4ons according to targets & evolu4on? • Which strategy for resilience?
University of Nice – Sophia Antipolis / Polytech’Nice-Sophia
Principles for resilience • From ini4al diagnos4c, inden4fied services and func4ons mainly affected At the regional level • Need for a clear policy about flooding and risk • Policy has to address the various spa4al levels and especially the block /district level which the most func4onal level • Responsibility of state to define and implement this policy • Based on land use regula4on (density and type of building) • Define level of risk

As a conclusion • Adapt the city to hazards as much as possible (city, district, block, parcel) • Develop the relevant policy • Invest in ac4ons in order to support services and func4ons deeply impacted by flood • Analyze the risk and monitor it (long term ac4on) • Open debate of level of risk & living with flood concept • Promote culture & educa4on about risk & flooding
