Peut-on concilier risques côtiers et planification viable ?

The city of New Orleans is turned toward the Gulf of Mexico through its settlement, its life style as well as its economic activities. This willingness to build on coastal areas has worsened the vulnerability of communities locating in areas at risk. The consequences of Hurricane Katrina demonstrate the importance of linking the urban structure to its ecosystem.

International case studies also bring critics and ideas to reduce risk vulnerability
