Peer review is a necessary process with a long history of complaints, including over-solicitation of a small number of reviewers, delays, inadequate numbers of reviewers, and a lack of incentives to provide strong reviews or avoid reviews with little helpful information for the author. In the era of Web-based distribution of research, through working paper or project reports, anonymous peer reviews are much less likely. The Journal of Ocean and Coastal Economics will use signed peer reviews and an open communication process among authors, reviewers, and editors. This approach, to be developed over time, should lead to stronger communication of research results for the Journal's readers. Lea el abstracto en español

Les populations d'Outre‐mer dépendent fortement des récifs coralliens, notamment pour la pêche, la protection des côtes face à l'érosion et aux évènements extrêmes, et le tourisme. Le maintien de ces services écosystémiques dans le temps dépend de l'état de santé des récifs coralliens et de leur résilience face aux pressions locales et au changement climatique. Les effets du changement climatique annoncés, et particulièrement l'augmentation de la température et l'acidification des océans, risquent d'impacter la provision de ces services en affectant l'état de santé des récifs coralliens. Etant donné les trajectoires d'émissions de gaz à effet de serre, une partie des effets du changement climatique sont inévitables. Ces effets se font déjà ressentir, comme le montrent les épisodes globaux de blanchissements des coraux, le dernier en date ayant particulièrement affecté la Grande Barrière de Corail en Australie où 60 % des coraux présents sur la Grande Barrière ont blanchis entre 2016 et 2017 (Hughes et al., 2017), et 30% sont morts. Même si la réduction des émissions de gaz à effet de serre pourrait réduire l'intensité de ces effets, il reste indispensable de les anticiper car les écosystèmes coralliens et les populations humaines qui en dépendent y sont vulnérables. La Polynésie française s'engage, avec les autres pays du Pacifique, en faveur de la lutte contre le changement climatique, notamment avec la Déclaration des pays de Polynésie « BOE Declaration » du 5/09/2018 (Cette déclaration provient du 49ème Forum des Iles du Pacifique, Yaren, Nauru, 3‐6 Septembre 2018) : "We reaffirm that climate change remains the single greatest threat to the livelihoods, security and wellbeing of the peoples of the Pacific and our commitment to progress the implementation of the Paris Agreement" Ainsi que par la Déclaration « Polynesian PACT » en amont de la COP21 (Déclaration de Taputapuatea dugroupe des dirigeants polynésiens, PACT, Papeete, 16 juillet 2015).C'est dans ce contexte que cette étude tente d'évaluer la vulnérabilité des récifs coralliens et des populations qui en dépendent en Polynésie française en utilisant des approches innovantes et interdisciplinaires. Dans ce rapport, la première partie décrit les approches utilisées pour évaluer la vulnérabilité et guider l'adaptation. La deuxième partie détaille les objectifs de l'étude. La troisième partie décrit la zone d'étude choisie. La quatrième partie détaille les méthodologies employées et les résultats de l'évaluation de la vulnérabilité, avec une sous‐partie sur la vulnérabilité écologique et le développement d'indicateurs de résilience, une sous‐partie sur l'évaluation de la vulnérabilité socio‐économique, et une sous‐partie concernant l'utilisation d'enquêtes de perceptiondes populations dépendantes des récifs coralliens sur les changements environnementaux. La cinquième partie propose des pistes pour l'adaptation en partant du diagnostic de la vulnérabilité et des documents de politiques publiques existants en Polynésie française. La sixième partie est consacrée l'évaluation de la vulnérabilité et l'adaptation. Enfin, la septième partie propose des recommandations pour les politiques publiques et pour la recherche.

International audience ; Ship strikes are one of the main human-induced threats to whale survival. A variety of measures have been used or proposed to reduce collisions and subsequent mortality of whales. These include operational measures, such as mandatory speed reduction, or technical ones, such as detection tools. There is, however, a lack of a systematic approach to assessing the various measures that can mitigate the risk of ship collisions with whales. In this paper, a holistic approach is proposed to evaluate mitigation measures based on a risk assessment framework that has been adopted by the International Maritime Organization (IMO), namely the Formal Safety Assessment (FSA). Formal Safety Assessment (FSA) is "a rational and systematic process for assessing the risk related to maritime safety and the protection of the marine environment and for evaluating the costs and benefits of IMO's options for reducing these risks". The paper conceptualizes the use of a systematic risk assessment methodology, namely the FSA, to assess measures to reduce the risk of collisions between ships and whales.

Despite the widespread use of nourishment in California, few studies estimate the welfare benefits of increased beach width. This paper relies on panel data funded by National Oceanic and Atmospheric Administration and other agencies. Beach choices of respondents were combined with beach attribute data to reveal how changes in width affect choice and the economic value of beach visits. We use a random‐utility approach to show that the value of beach width varies for different types of beach uses: water contact, sand‐, and pavement‐based activities. We also find that the marginal value of beach width depends on initial beach width. (JEL Q50)
