Development of Marine Resources

Marine resources and their exploitation, recovery and economic networks they generate are here from the perspective now inevitable growing environmental constraints, policy management and technical innovation.

A historical perspective shows that Ocean and its adjacent seas at all times, allowed coastal communities to adapt to a very volatile environment through many technological changes.

The recent development of marine biotechnology , the discovery of a great pharmacopoeia especially in reef environments , the development of marine renewables , are examples which show that man can develop through these new technologies property and services of the ocean.

André Monaco is Emeritus Director of Research for the French national research center (CNRS). His research interests concern marine sedimentology and geochemistry. He was responsible for part of the organizing committee for several French and European programs and has been guest editor for four special issues in international journals.

Patrick Prouzet is Director of Research focusing on the ecosystemic approach at Ifremer in France. He specializes in the biology and dynamics of anadromous fish such as Atlantic salmon and eels. He is the author or co-author of several works on these species or on estuary fishing.
