The Pacific Ocean Pollution Prevention Programme (PACPOL) mission is to protect public health, safety, environment and natural resources of the Pacific Islands from the effects of ship sourced marine pollution

Marine pollution is widely recognised as one of the four major threats to the world’s oceans, along with habitat destruction, over-exploitation of living marine resources and invasive marine species. Spills of oil and other chemicals into the marine environment, both from ships and land-based sources, is a significant source of pollution.

Mangrove ecosystems are threatened by climate change. We review the state of knowledge of mangrove vulnerability and responses to predicted climate change and consider adaptation options. Based on available evidence, of all the climate change outcomes, relative sea-level rise may be the greatest threat to mangroves. Most mangrove sediment surface elevations are not keeping pace with sea-level rise, although longer term studies from a larger number of regions are needed. Rising sea-level will have the greatest impact on mangroves experiencing net lowering in sediment elevation, where there is limited area for landward migration. The Pacific Islands mangroves have been demonstrated to be at high risk of substantial reductions. There is less certainty over other climate change outcomes and mangrove responses. More research is needed on assessment methods and standard indicators of change in response to effects from climate change, while regional monitoring networks are needed to observe these responses to enable educated adaptation. Adaptation measures can offset anticipated mangrove losses and improve resistance and resilience to climate change. Coastal planning can adapt to facilitate mangrove migration with sea-level rise. Management of activities within the catchment that affect long-term trends in the mangrove sediment elevation, better management of other stressors on mangroves, rehabilitation of degraded mangrove areas, and increases in systems of strategically designed protected area networks that include mangroves and functionally linked ecosystems through representation, replication and refugia, are additional adaptation options.

Assisting the South Pacific Regional Environment Programme's (SPREP) island members to plan, prepare and respond to marine spills is one of the four activity areas of the Pacific Ocean Pollution Prevention Programme (PACPOL). PACPOL activities currently include a regional risk assessment regional and national contingency plans, formulation of a regional equipment strategy and facilitating regular workshop to discuss marine spill issues. The aim of this initial shipping risk study was to identify and quantify the shipping routes, frequency of voyages and types of cargoes transported in the region as well as to map shipping incidents, navigational hazards and assess the risk of marine pollution across the region, EEZs and at a port scale. The regional and EEZ distribution of risk potential showed clusters of high risk in Fiji, French Polynesia, Papua New Guinea and Solomon Islands. Smaller clusters occurred in Tonga, the Samoa's, Vanuatu and the corridor from Chuuk northward past Guam and the Northern Mariana Islands. Another potential marine pollution risk for the Pacific is the fuel oil and cargoes remaining on WWII shipwrecks deteriorating in the waters of the region. More than 1000 such wrecks have been identified amounting to over 3 million tons of shipping lost.
