FROM CHAOS TO CONSILIENCE: THE NEED FOR SCIENCE-BASED POLICY TO PREVENT MARINE DEGRADATION FROM LAND-BASED ACTIVITIES SHELLEY MARGOT LEXMOND B.Sc. (Acadia), LL.B. (Dalhousie) A THESIS SUBMITTED FOR THE DEGREE OF DOCTOR OF PHILOSOPHY FACULTY OF LAW NATIONAL UNIVERSITY OF SINGAPORE 2002 1 Acknowledgements I would like to thank my two supervisors, Douglas Johnston and Bob Beckman, for their guidance and advice in charting my course. I am especially indebted to Douglas, a “master mariner”, in my opinion, for his many hours in the wheelhouse, helping to navigate the numerous shoals and bearing with me through black water and calm seas, and the occasional storm. David VanderZwaag of Dalhousie Law School, Canada, and Mike Bewers formerly of GESAMP and the Department of Fisheries and Oceans, Canada, each undertook the dual role of mentor and friend, for which I am deeply grateful. To Mike, my express thanks for providing access to the international scientific community. My gratitude extends to the numerous scientists who gave so generously of their time. Individuals too numerous to list, from diverse disciplines, countries, and agencies are thanked for comments, insight, time, information, inspiration, and opening portholes that would have otherwise remained closed. In particular, Ambassador Hasjim Djalal of Indonesia and Ian Townsend-Gault of the University of British Columbia kindly provided a crow’s nest from which to observe the roiling currents of international law and science through invitations to attend many meetings of the Technical Working Groups on Legal Matters, Marine Scientific Research, and Marine Environmental Protection and the Annual Workshops, all of which were components of the CIDA-funded initiative, Managing Potential Conflicts in the South China Sea. Cynthia Barlow Marrs has been a terrific friend and compass rose, logging hours of editorial input. Glen Hearns, and Dr. Marie Mater are saluted for being stalwart shipmates and fielding SOS calls. On a personal level, I wish to thank my husband, Bill; my parents, Joy and Elfed Evans: and Judith Johnston for their support and encouragement; and finally, my children, Kyle, Drew, and Sian for being good sailors when the waters got rough. 2 Contents Acknowledgements i Contents ii Acronyms viii Summary x Introduction Marine Degradation from Land-based Activities: Navigating Chaos and Complexity 1 Part I Regime Chaos and MDLBA 1 A.

Acknowledgement of this comes in the form of the 109 nation states’ endorsement of the 1995 Global Programme of Action for the Protection of the Marine Environment from Land-based Activities (“GPA”).1 The fact that there is no legally binding global treaty, but only the morally binding GPA is suggestive of, at the very least, the perceived intractability of issues associated with MDLBA.
