BRGM actions in links with the
ICZM approach
C. Vinchon, D. Idier, G.Le Cozannet, C. Oliveros
Coastal Risk and Climate Change Unit
Colloque Croissance Bleue -Athènes -25 novembre 2013
The coastal zone frame
> ICZM integrated approach of territories
> Coastal risks (erosion, marine inundation)
•
Increased by climate change (sea level rise, extreme
events)
• Increased by societal changes (changes in land use,
demographic increases, migratory processes,….
=>Need of a holistic approach of risk, and
implementation transdisplinary approaches
>
European framework directives
•
•
•
MSFD, WFD, FD
Ecosystemic approaches : Sea bed and water column
integrated as support for biocenoses
Flood risks
