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...

Climate change is anticipated to affect freshwater resources, but baseline data on the functioning of tropical watersheds is lacking, limiting efforts that seek to predict how watershed processes, water supply, and streamflow respond to anticipated changes in climate and vegetation change, and to management. To address this data gap, we applied the distributed hydrology soil vegetation model (DHSVM) across 88 watersheds spanning a highly constrained, 4500 mm mean annual rainfall (MAR) gradient on Hawai‘i Island to quantify stream flow at 3-h time-steps for eight years in response to the independent and interactive effects of (1) large observed decrease in MAR; (2) projected warming and altered precipitation; and...

In the tropics, ample freshwater is the primary resource supporting thriving human and ecological communities. In the Pacific Islands, many watersheds are threatened by climate change, urban encroachment, and invasion by water-demanding exotic plant species like strawberry guava (SG). To maintain an adequate freshwater supply, adaptive management strategies are needed to address these concerns while confronting operational barriers to implementation. We developed a prototype watershed decision support tool (WDST) that incorporated: (i) distributed hydrology modeling to quantify effects of climate change and SG invasion on freshwater yield; (ii) a decision support tool that linked potential changes in yield with...
