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...

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...

Hawai‘i’s isolation, paired with limited water resources, make the archipelago sensitive to reductions in water availability. Drought can take different forms, varying across Island geographies with respect to frequency, intensity, duration, and extent. A drought event can exert hydrological, agricultural, ecological, and socio-economic impacts – and these impacts have been growing over the past century as droughts have become more frequent and severe. While the impacts of drought in Hawai‘i have been recently documented, important gaps remain in understanding these dynamics when engaging with multiple other stressors such as invasive species, shifting fire and climate patterns, pests, and pathogens. In particular,...

Increasing temperatures, decreasing rainfall, and more intense droughts and storms are threatening the health and wellbeing of ecosystems and communities across Hawai‘i and the Pacific Islands. Future rainfall and temperature projections provide some insight into future change, but uncertainty remains in when, where, and how impacts will manifest, presenting daunting challenges to natural resource managers. The need for high-quality reliable climate data and translated products that can be used to proactively plan for changes in the region has never been greater. This is especially true in underserved communities where access to data and resources for integrating climate information into management planning is limited....

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...

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...

Some areas of the U.S. Affiliated Pacific Islands (USAPI) are experiencing a decline in precipitation and streamflow and an increase in the 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. As ecosystems become altered by invasive species and as particularly hotter, more variable climates emerge, it is critical that scientists produce locally relevant, timely, and actionable science products for managers to prepare for and cope with the impacts of drought. Simultaneously, it is important that managers are able to both access this information and shape the types of data products...
