ContestaLon  of  knowledge  on  DRR  

La  Faute  sur  Mer  2007  RPP,  and  local  opposiLon  to  DRR  policy.  Which  knowledge  for  whom?  

Structure  

1.  The  context  :  the  more  we  know,  the  more  we  lose….  2.  DRR  policies  necessary,  yet  limited.  3.  IdenLfying  limitaLons  :  a  quesLon  of  informaLon  and  knowledge  for  assessing  DRR…  4.  But  not  only  a  quesLon  of  informaLon  and  knowledge  as  such….  THE  challenges….  

1.  The more we know, the more we lose? Assessments on disaster frequencies and losses look paradoxical (White et al. 2001): « the more we know, the more we lose…. »

Papers on resilience in peer-review journals. (Kuhlicke, 2011)

A. The more we know

B. The more we lose???

Yet, C….

How to reduce losses even more?

Poorly  prevenLon  oriented   More  prevenLon  oriented  

DRR  policies  more  prevenLon  oriented…yet  sLll  with  peak  losses  (as  with  Xynthia  related  disasters…).  Where  do  we  find  the  most  disaster  prone  areas?    

2.  DRR  policies  necessary,  yet  limited.….

Losses  intensiLes  

Level  of  water  

AND  level  of  water  does  not  explain  losses  experienced  only,  according  to  experience  returns  and  insurance  data  (plurifactoriality…..).    How  to  share  that?

Insights  

•  How  to  reduce  more  informaLon  fragmentaLon  on  DRR  between  insLtuLons  and  stakeholders?    

•  How  prevenLng  more  disasters  with  local  stakeholders?  

•  “Increasing  the  quality  and  coverage  of  data  is  seen  as  central  to  operaLonalising  DRR  policies,  but  success  does  not,  however,  hinge  simply  on  the  provision  of  more  accurate  and  comprehensive  data”
