2 -4 october 2006IHO MACHC seminar - Acapulco Integrated costal zones management Serge ALLAIN SHOM - France

2 – 4 october 2006IHO – MACHC seminar – Acapulco 2 Integrated costal zones management - ICZM Definition ICZM deals with The management and the substainable use of the coastal zones into consideration the economic and social development linked to the existence of the sea while safegarding, for the future and present generations, the biologic and ecologic fragile equilbrium of the coastal zone and the landscapes

2 – 4 october 2006IHO – MACHC seminar – Acapulco 3 ICZM This definition adds : The setting up of an ICZM requires the creation of institutional instruments and standards making possible the participation of the actors as well as the coordination of the objectives, of the policies ans of the activities and leads to deal with the problems in a global way which takes into account the interaction between all the components of the environment.

2 – 4 october 2006IHO – MACHC seminar – Acapulco 4 ICZM This supposes several levels of integration - Geospatial : Land and Sea core data in a seamless representation - Administrative: coordination between the actors - Sectorial : coordination of activities - Temporal : Short Time and Long Time, sustainable development

2 – 4 october 2006IHO – MACHC seminar – Acapulco 5 ICZM Recognized at the international level - Several international conventions (Barcelona 1995, Ramsar 20002,…) - IOC and GEO recommendations for multi-risks mitigation (meteoroly, tsunamis, pollution, coast line protection) - regional project for the implementation of multi-risk and tsunami warning systems in Indian ocean, Mediterranean sea and Carribean sea.
