| Zusammenfassung |
| RETINA is a project which studies the opportunity for adaptation in the aftermath of flood
events. To handle this research question, we consider adaptation to flood risk at
individual and collective scale as well as the influence of the urban planning regulation
(Flood risk mapping). For the purpose of this research, collective adaptation means
actions that are undertaken at collective scale such as dikes, relocation of collective
infrastructures (roads, treatment plant/¦) and individual adaptation means actions
decided at individual level (households, enterprises or farmers) such as relocation,
elevation of critical components, new organization/¦. In this presentation, we focus on
individual adaptation and analyse which are the mechanisms that incite or constrain the
adaptation to flood risk of individual assets considering their own trajectory. The
originality of our approach is to carry out long term post-flood assessments and
comprehensive interviews at individual scale. To catch the drivers of adaptation, we
sequenced the interview guide in three periods: 1/ the situation before the reference
event occurred, 2/ what happened during and just after the flood event, 3/ what
happened from the flood event until the moment of the interview. Two case studies have
been chosen. The first case study is the Aude department where an exceptional
flooding occurred in 1999. The second case study is the Var department where
more recent and frequent flood events occurred in 2010, 2011, 2014. On each case
study, we plan to conduct about fifty interviews including households and economic
activities.
In this presentation, we will develop methodological aspects on long term post-flood
damage assessments. Carrying out a long term post-flood assessment enabled us to consider
adaptation to flood risk among the whole of strategic decisions a household or an enterprise
has to take. Moreover, we found out that contrary to what is usually assumed, the fact that the
reference event was relatively ancient (fifteen years on Aude case study), we collected precise
data on flood damage and the recovery process. We will also present some results concerning
a specific type of individual adaptation i.e relocation. In particular, we found out
that relocation was a long term process which required then long term post-flood
assessments to be analyzed. Interviews also revealed that even if it is an action often
promoted, in practice, a lot of constraints have to be overcome by households and
enterprises.
Finally, we will give some insights for operational applications of this research. Mainly, it
can be useful to improve flood damage functions or to help decision makers to define
adaptation policies. |
