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
