PREFACE
This book has been conceived with the aim of contributing to the International
Conference on Ocean Management in Global Change (Genoa, June 22-26,
1992) and to the ocean sciences’ debate on the conceptual framework and targets
of sea management. The former objective is justified by the background of the
Conference, which is aimed at encouraging a multidisciplinary approach to the
management of the sea and implementing comprehensive approaches to sea
resource use and environmental protection and conservation. The latter objec­
tive is justified by the growing importance which literature has been attributing
to the theoretical and methodological bases of sea management since the late
Seventies.
The thesis which supports this work is that the more marine scientists are
capable of moving towards a general system-based approach to sea uses and
environmental implications, making holistic views, and creating common forms
for implementing multidisciplinary views, the more sea management will have
the opportunity of advancing.
My thanks are due to Stella Maris Vallejo and Moritaka Hayashi, United
Nations Office for Ocean Affairs and the Law of the Sea, and Hance D. Smith,
Department of Maritime Studies of the University of Wales (Cardiff), for their
stimulating conversations about the background and goals of sea management,
to Alberto Bemporad, the General Commissioner of the Specialized Interna­
tional Exhibition “Christopher Columbus: Ships and the Sea”, and Giorgio
Doria, the Co-ordinator of the Technical-Scientific Committee of the Ente
Colombo 92, who encouraged me to offer this contribution to the scientific
debate which is expected in the context of the Celebrations of the Quincentenary
of the Discovery of the Americas.
