Ce rapport est l'un des principaux résultats de l'atelier régional Sea'ties Pacifique qui s'est tenu du 10 au 12 juillet 2023 à Nadi (Fidji). L'atelier a été organisé par la Plateforme Océan & Climat, le Programme régional océanien de l'environnement (PROE), et le Pacific Climate Change Pacifique (PCCC), avec le soutien financier du Fonds de coopération économique, sociale et culturelle pour le Pacifique (« Fonds Pacifique », Ministère de l’Europe et des Affaires Etrangères), du PCCC, et du PROE par le biais du programme d’assistance technique de l’Initiative Kiwa. Le rapport fournit une vue d'ensemble des défis actuels en matière d'adaptation dans la région du Pacifique, ainsi que des initiatives inspirantes pour les relever. Les conclusions de ce rapport s'appuient sur les points de vue exprimés lors d’entretiens et sur les discussions de l'atelier lui-même. Il souligne et démontre à quel point, dans une région où de nombreuses îles sont de faible altitude, où la grande majorité de la population vit au bord de l'océan et où la côte s'urbanise rapidement, l'élévation du niveau de la mer reste une question existentielle et qu'il est primordial d'accélérer les mesures d'atténuation et d'adaptation.

Humanity has altered the planet in many detrimental ways, from the warming of our climate to the ever-diminishing wildernesses on land and in the sea. But in such a complex system as the Earth, science must always keep searching – for both solutions to problems already identified and new threats coming our way. UNEP’s Frontiers Report does this by identifying and exploring areas of emerging or ongoing environmental concern. The 2022 edition delves into three issues: noise pollution in cities, the growing threat of wildfires and shifts in seasonal events – such as flowering, migration and hibernation, an area of study known as phenology.

Humanity is waging war on nature. This is senseless and suicidal. The consequences of our recklessness are already apparent in human suffering, towering economic losses and the accelerating erosion of life on Earth. This report represents a scientific blueprint for howclimate change, biodiversity loss and pollution can be tackled jointly within the framework of the Sustainable Development Goals. The report is a synthesis based on evidence from global environmental assessments.

During 10–21 September, quantitative surveys were carried out of birds and flying foxes using the same techniques as applied in earlier surveys, and searches carried out for a rare parrot and lizard. Bird counts showed that the lupe or Pacific imperial-pigeon population has recovered following a decline between 1994 and 2004 though the current hunting rate is considered unsustainable. Miti or Polynesian starling numbers have gradually declined over the period 1994–2012 which is a concern and hard to explain. Rat predation is a possible cause. There was also an indication that pekapeka or white-rumped swiftlet numbers have declined though more investigation is needed to confirm this. We were unable to find any hega or blue-crowned lory though a few individuals were reported to us. Numbers are clearly very low and the next step must be to gain a better understanding of where the species regularly occurs so that management can be applied

The restoration of the small offshore islands of Nu’utele (108ha) and Nu’ulua (25ha) has long been identified as a priority for biodiversity conservation in Samoa. The first step towards restoration was the aerial spreading of brodifacoum to eradicate Pacific rats (Rattus exulans) in August 2009. Procedures for the eradication followed those used in New Zealand and involved technical experts from that country. Particular challenges included a tight operational time-frame (two months), technical problems magnified by the remote location, variable reliability of weather forecasting,working with the local community, and mitigating rodenticide exposure risks for the friendly ground-dove (Gallicolumba stairi) (IUCN: vulnerable). Solutions to these challenges are discussed as guidance for similar projects in remote island locations. Follow-up monitoring between August 2009 and March 2010 indicated that the eradication had been successful, but Pacific rats were detected on Nu’utele in May 2011. Nu’ulua has yet to be rechecked in 2011. DNA analyses are being organised to determine if these rats are survivors or re-invaders.
