Aim To provide the first regional analysis of contemporary drivers of Pacific Island fire regimes. Location Islands of Palau, Yap, Guam, Rota, Tinian, Saipan, Chuuk, Pohnpei, Kosrae. Time Period 1950-present. Methods We used land cover, soil maps and contemporary fire histories to (1) describe the relationships among fire activity, vegetation, rainfall and island geography and population; (2) examine the spatial associations of forest and savanna vegetation with respect to fire and soil types; and (3) link fire and savanna distribution to intra-annual and inter-annual rainfall variability. Results Savanna extent was positively correlated with island age and the range of mean monthly rainfall. The percent of area...

The Hawai‘i Drought Knowledge Exchange project has been successfully piloting three sets of formal collaborative knowledge exchanges between researchers and managers to co-produce customized, site specific drought data products to meet the needs of their partners. Through these pilots, knowledge co-production has demonstrated how active collaboration between researchers and managers in the design and production of data products can lead to more useful and accessible applications for drought planning and management. Resource managers have strongly embraced the need for better and more timely information on climate change, variability and drought, as these stressors exert a large and costly impact on resources...

Climate change poses significant challenges to food production, natural resources management, and public health. Initiatives like ‘Climate-Smart Agriculture” (e.g., FAO, UNDP) and the growing field of ‘Climate Services’ are emerging globally to provide stakeholders (producers, managers, communities) with better climate-related information and solutions to cope with increasing climate variability. The long-term relationships and diverse professional networks cultivated by Cooperative Extension faculty places them in a unique and critical position to help clients and stakeholders sustain and improve food security, ecosystem services, and local health and livelihoods in the face of climate change. The intent of the...

Under climate change, ecosystems are experiencing novel drought regimes, often in combination with stressors that reduce resilience and amplify drought’s impacts. Consequently, drought appears increasingly likely to push systems beyond important physiological and ecological thresholds, resulting in substantial changes in ecosystem characteristics persisting long after drought ends (i.e., ecological transformation). In the present article, we clarify how drought can lead to transformation across a wide variety of ecosystems including forests, woodlands, and grasslands. Specifically, we describe how climate change alters drought regimes and how this translates to impacts on plant population growth, either directly...

Over the past century, Hawaiʻi has experienced a pronounced decline in precipitation and stream flow and a number of severe droughts. These changes can have wide-reaching implications, affecting the water supply, native vegetation and wildlife, wildfire patterns, and the spread of invasive species. Several climate-related factors are influencing Hawaiˈi’s landscapes and contributing to these changes. These include climate change, climate variability, and drought (referred to collectively as CCVD). Climate variability describes how the climate fluctuates on a yearly basis around average values, while climate change describes patterns of long-term continuous change in the average. While it is understood that CCVD...

This product provides a metric of per-pixel fire risk for the main Hawaiian Islands (excluding Niʻihau) at 30 m x 30 m resolution. The product provides raw values of annual fire probability for the whole year, dry season and wet season as well as binned categorical fire risk values (Low, Moderate, High, Very High) for the same time frames. Categorical thresholds for fire risk are derived from probabilities observed at the time of historical fires in each county. This is a modeled data product trained using historical fire perimeters, ignition density, mean annual temperature, mean annual soil moisture, historical rainfall data , and remotely sensed vegetation cover.

Final Report: Extension Climate Forum Hawaiʻi: Sharing Climate Knowledge, Supporting Our Communities
Cooperative Extension agents and specialists in the College of Tropical Agriculture and Human Resources (CTAHR) at the University of Hawaii at Manoa (UHM) are in a critical position to improve food security, ecosystem services, and local livelihoods in the face of climate change due to their expertise and client-based relationships. However, there has been little systematic effort to increase the knowledge of climate science or climate change mitigation and adaptation among Cooperative Extension faculty in the Pacific region. The Hawaii Extension Climate Forum was designed to engage Cooperative Extension faculty in critical dialogue about the impacts of climate change on agriculture and natural resources in Hawaii....

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...

This workshop will build capacity within the Cooperative Extension Service (CES) in the College of Tropical Agriculture and Human Resources at the University of Hawaii at Manoa (CTAHR-UHM) to effectively incorporate climate science and climate-related information into CES programs and identify locally relevant strategies for climate adaptation. This effort will expand the work and impact of the Pacific Island Agroforesty Adaptation Initiative (PIAAI), a partnership between PICCC and College of Tropical Agriculture and Human Resources at the University of Hawaii at Manoa (CTAHR-UHM), currently focused on the Territories of Guam and American Samoa, and the Commonwealth of the Northern Mariana Islands. The Hawaii-focused...

Wildfire is a significant yet underappreciated issue on Pacific Islands that threatens ecosystems from ridge-tops to reefs, including native species, waters, human communities, and natural and cultural resources. In the Hawaiian archipelago, the percentage of land burned annually is equal or greater than that burned across the western United States, with most fires occurring in drier nonnative grasslands and shrublands, which make up 25% of Hawaiʻi’s total land area. As island communities face increased wildfire risk due to climate change and other factors, such as continued plant invasions, collaborative bio-cultural stewardship approaches to adaptation will be critical to wildfire management. Fire causes and effects...

The climate in Hawai‘i is changing, and alterations in rainfall amount and distribution have implications for future vegetation cover, non-native species invasions, watershed function, and fire behavior. As novel ecosystems and climates emerge in Hawai‘i, particularly hotter and drier climates, it is critical that scientists produce locally relevant, timely and actionable science products and that managers are able to access the best-available science. Managers and researchers have identified that a knowledge exchange process is needed for drought in Hawai‘i to allow for formal collaboration between the two groups to co-produce drought data and products. To address this need, this project will pilot a focused...

2018 was a record-breaking year for wildfires in Hawai‘i with over 30,000 acres burned statewide, including the habitat of the Oʻahu chewstick, a critically endangered flowering plant with less than 50 individuals remaining. The frequency and severity of wildfire in Hawai‘i has been increasing, and this trend is predicted to worsen with climate change. Wildfires are promoted by highly flammable invasive plants, which can spread across the landscape, providing a widespread fuel source to feed large fires that are hard to control. However, different plant species vary in their flammability, so wildfire risk depends not only on climate, but also on which plants are present. A major concern is that new non-native plants...

The State of Hawai'i passed legislation to be carbon neutral by 2045, a goal that will partly depend on carbon sequestration by terrestrial ecosystems. However, there is considerable uncertainty surrounding the future direction and magnitude of the land carbon sink in the Hawaiian Islands. We used the Land Use and Carbon Scenario Simulator (LUCAS), a spatially explicit stochastic simulation model that integrates landscape change and carbon gain-loss, to assess how projected future changes in climate and land use will influence ecosystem carbon balance in the Hawaiian Islands under all combinations of two radiative forcing scenarios (RCPs 4.5 and 8.5) and two land use scenarios (low and high) over a 90 year timespan...

Droughts in the Hawaiian Islands can enhance wildfire risk, diminish freshwater resources, and devastate threatened and endangered species on land and in nearshore ecosystems. During periods of drought, cloud-water interception, or fog drip (the process by which water droplets accumulate on the leaves and branches of plants and then drip to the ground) in Hawai‘i’s rain forests may play an important role in providing moisture for plants, reducing wildfire risk within the fog zone, and contributing to groundwater recharge (the process by which water moves downward from the surface through the ground to the groundwater table) that sustains water flow in streams during dry periods. Estimates of the changes in water...
