L'objectif de l'étude est de proposer un cadre juridique propice à la biosécurité de Wallis et Futuna, qui réinvestisse les dispositions préexistantes en les étoffant et les renforçant. Cela répond à un contexte où les textes relatifs à la biosécurité de Wallis-et-Futuna étais épars, hétérogènes et en partie obsolètes. Les enjeux de biosécurité poussent à la réflexion vers un corpus complet, cohérent et actualisé en la matière. Le droit international et régional, notamment les directives de Port-Moresby de 2007, permettent d’alimenter la réflexion en la matière. Pour réaliser cette proposition ont été réalisés : (i) des entretiens, (ii) des analyses bibliographiques et synthèses de doctrine, de droit comparé, de droit régional, de droit international, proposition légistique et (iii) des analyses bibliographiques, propositions de listes et de fiches techniques.

Fisheries data assembled by the Food and Agriculture Organization (FAO) suggest that global marine fisheries catches increased to 86 million tonnes in 1996, then slightly declined. Here, using a decade-long multinational ‘catch reconstruction’ project covering the Exclusive Economic Zones of the world’s maritime countries and the High Seas from 1950 to 2010, and accounting for all fisheries, we identify catch trajectories differing considerably from the national data submitted to the FAO. We suggest that catch actually peaked at 130 million tonnes, and has been declining much more strongly since. This decline in reconstructed catches reflects declines in industrial catches and to a smaller extent declining discards, despite industrial fishing having expanded from industrialized countries to the waters of developing countries. The differing trajectories documented here suggest a need for improved monitoring of all fisheries, including often neglected small-scale fisheries, and illegal and other problematic fisheries, as well as discarded bycatch.

Despite the considerable expansion in the number and extent of marine protected areas during the past century, coverage remains limited amid concerns that many marine protected areas are failing to meet their objectives. New estimates of global marine protected area, based on the database maintained by Sea Around Us, revealed a degree of progress towards protecting at least ??% of the global ocean by ????. It is estimated that . ?,??? marine protected areas, covering c. ?.??% (?? million km? ) of the oceans, had been designated by the end of ????. However, protection is generally weak, with c. one-sixth (?.? million km? ) of the combined area designated as no-take areas (i.e. fishing and other extractive activities are prohibited). Additional large tracts of ocean will need to be protected to reach the ??% target, and we investigate hypothetical scenarios for such expansion. Such scenarios offer a one-dimensional measure of progress as they do not address aspects of other global targets, such as Aichi Target ??, which will help to ensure that marine protected areas meet their objectives and achieve conservation outcomes.
