Mi.ga.on: what ci.es can do

Adap.ve ac.ons • Physically adapt to new boundaries: – building design – seVlements – physical infrastructures – management of urban «asseVs» (water, air, soil, biodiversity, energy flows)

• Increase resilience • Prepare for extreme events (mapping, early warning, etc.)

• Protect against losses (management schemes, insurances, etc.)

Flexibility and adap.veness

Resilience?

Not all damages can be prevented Aim: increase resilience Resilience is defined as: – The ability of a system to absorb shock and carry on performing the func7on that it was designed to do”

Uncertainty -­‐ Flexibility • Climate change impacts are s.ll not perfectly known in their extend (depends also on the success of mi.ga.on efforts) • Adapta.on measures are costly • Climate change adapta.on needs to be considered as an on-­‐going, cyclic process
