Indigenous communities make up less than 5% of the world’s population while stewarding 85% of biodiversity on the planet. In Hawaii, Native Hawaiian language resources, including proverbs, stories, and chants, provide glimpses to how people adapted with environmental rhythms, seasons, and offerings. Drought, the absence of water for agricultural, economic, and social use for a period, is important as a main water resource in Hawai‘i are clouds captured and purified by high island mountains in the middle of the Pacific Ocean. This research provides insight on Native Hawaiian relationships to drought historically as well as current practices within community-based management. Of importance are historical records of...

Freshwater is a critical driver for island ecosystems. In Hawai‘i, though rainfall intensity has increased, total rainfall has been on the decline for the last two decades and, as a result, reduced streamflow. Climate change has fundamentally altered the water cycle in these tropical islands. The changes in dynamic patterns of streamflow could result in temporal and spatial differences in the fluvial, estuarine, and coastal habitats. These habitats support the nine native aquatic species in Hawaii at different stages of their amphidromous life cycle. To examine how changes in streamflow regime has impacted habitat quality for native migratory aquatic species, an ongoing project has examined statewide long-term stream...
As a low-lying island nation, the Republic of the Marshall Islands (RMI) is at the forefront of exposure to climate change impacts, including, primarily, inundation (coastal flooding). Increased water levels can stem from episodic events (storm surge, wave run-up, king tides) or from chronic conditions (long term sea-level rise). Land elevation is the primary geophysical variable that determines exposure to inundation in coastal settings. Accordingly, accurate coastal elevation data are a critical input for assessments of inundation exposure and vulnerability. Previous research has demonstrated that the quality of data used for elevation-based assessments must be well understood and applied to properly model potential...

As a low-lying coastal nation, the Republic of the Marshall Islands is at the forefront of exposure to climate change impacts. The Republic of the Marshall Islands has a strong dependence on natural resources and biodiversity not only for food and income but also for culture and livelihood. However, these resources are threatened by rising sea levels and associated coastal hazards (storm surges, saltwater intrusion, erosion, etc.). High-quality data for atoll ‘ridge to reef’ (land and ocean) areas are needed to provide remote communities with the tools and strategies to make adaptation efforts before disasters occur. Although the Republic of the Marshall Islands’ National Strategic Plans recognize the need to...

This exerpt comes from a Bishop Museum collection called, “The Chants of James Palea Kapihenui Kuluwaimaka.” The explanation about words found in traditional and modern pule and mele is an example of the rich environmental information that continues to be found in Hawaiian resources that are often overlooked or not considered valuable. James Palea Kapihenui Kuluwaimaka (Kuluwaimaka) was born in Naʻalehu, Kaʻū, in 1845. He had an incredible memory and could recant 1,500-1,700 lines within an ancient chant effortlessly (Honolulu Advertiser, 1937). He was the court chanter for King David Kalākaua and Queen Liliʻuokalani. Kuluwaimaka continued to serve the queen even after deposed whenever she made appearances publically...
Streams delineated to model potential annual sediment transport and yield. Only areas with high flow accumulation values were included to model streams that are likely permanent.

Freshwater is a critical driver for island ecosystems. In Hawaiʻi, though rainfall intensity has increased, total rainfall has been on the decline for the last two decades and, as a result, streamflow has also been reduced. The changes in dynamic patterns of streamflow could result in impacts to river, estuarine, and coastal habitats. In turn, these changes also affect the nine native Hawaiian aquatic species found in these habitats at different stages of their amphidromous life cycle (in which they migrate from fresh to salt water or vice versa). To examine how changes in streamflow regime have impacted habitat quality for native migratory aquatic species, an ongoing project has been examining statewide long-term...

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...
