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
