This was done in the interest of strengthening regional cooperation and in broadening the range of experience and expertise at the meetings, The governments of Germany, Japan and The Netherlands were also invited to attend, due to their past and present involvement with coastal protection in the region. Unfortunately, they did not attend. In assessing the coastal protection needs of the region during the First Coastal Protection Meeting, it was unanimously agreed that the provision of effectivp coastal protection systems required consideration in the broadest context and over the long-PI' time-frame. The construction of engineered coastal protection structures are therefore only one particular aspect of the provision of effective coastal protection. Both SPREP and SOPAC have encouraged the meetings to openly discuss all t.ho issues associated with the Forum's request, and to arrive at the recommendations in a transparent manner. SPREP has appreciated SOPAC's assistance and cooperation in organising and running these meetings. With the necessary support the two agencies will be able to continue with the activities identified during the meetings. These meetings have successfully layed the ground-work for the effective provision of coastal protection in the region. It is now hoped that the support necessary to maintain the momentum generat(~d by these successful meetings will be forthcoming. Viii A.
