Ecosystems such as coral reefs and mangroves provide an effective first line of defense against coastal hazards and represent a promising nature-based solution to adapt to sea-level rise. In many areas, coral reefs cause waves to break and lose energy, allowing for sediment to accumulate on the inshore portion of reef flats (i.e. the shallowest, flattest part of a reef) and mangroves to establish. Mangroves cause further attenuation (i.e. energy loss) waves and storm surge as water moves through roots and trunks of the trees. Together, these ecosystems provide valuable protection from coastal flooding, but is unclear how this protection may be affected by sea-level rise. An assessment of future sea-level rise vulnerability...

Pacific Island societies value, depend on, and actively manage terrestrial and marine ecosystems for the multiple benefits they provide, including those associated with plant and animal abundance, resilience to natural disasters, and the flow of water, soil, and nutrients. New ecosystem service models developed for Pacific Island landscapes now integrate land-to-sea connections, allowing us to assess how land-based management actions and threats (e.g. changes to climate and land cover) affect ecosystem benefits, from ridge to reef. Affecting actual change on the ground, however, depends on how scientific information is accessed and used by managers and other decision makers who have the capacity to influence ecosystem...

Coral reefs are threatened by climate change because warming ocean temperatures are causing corals to bleach (i.e. lose the algae that provides them with the majority of their energy) which can lead to coral starvation and death. Local environmental conditions can contribute to either the resilience or susceptibility of corals to the global stress of climate change. One such factor is the local nutrient input from terrestrial sources. Corals near remote islands with abundant seabird populations have been found to have increased growth rates and are more resilient to bleaching events than corals near islands without seabirds. Seabirds supply the reef with ample nutrients via their guano (seabird excreted waste) and...

Coral reefs are declining worldwide due to a combination of stressors, but climate induced ocean warming is the biggest threat. Warming oceans lead to ‘coral bleaching’ and frequent death, compromising the structure and function of reefs. The increasing frequency and severity of bleaching means that human intervention is needed to support the adaptive capacity of reefs. Most proposed interventions involve the movement of corals, but the outcomes of these strategies are almost completely unknown. To bridge this knowledge gap, this project aims to assess how restoration to enhance resilience within coral reefs can effectively reduce climate change threats while also gaining a better understanding of socio-cultural...

Coral reefs are critical providers of food, economic opportunity, and cultural value in the Pacific Islands. Coral bleaching events, driven by extreme water temperatures, jeopardize reefs’ ability to continue providing these services. Climate change is increasing the frequency and intensity of marine heat waves leading to bleaching events, reducing the amount of time for full recovery, and increasing the chances of permanent damage to reefs. Reef managers urgently need strategies that will improve reef resilience, increasing the reefs’ ability to withstand harsh conditions or recover quickly after damage. Example strategies include restoring coral in areas with good conditions for coral survival, protecting naturally...
