Investing in nature-based solutions: Cost profiles of collective-action watershed investment programs
Abstract: Worldwide, an increasing number of watershed management programs invest in nature-based solutions (NbS) to water security challenges. Yet, NbS for water security currently are deployed at well below their hypothesized cost-effective global potential, with uncertainty about costs identified as one key constraint on increased investment. Data on administrative and transaction costs of watershed investment […]
Read MoreTourism water use during the COVID-19 shutdown: A natural experiment in Hawai‘i
By Nathan DeMaagd, Peter Fuleky, Kimberly Burnett, and Christopher Wada A recent study published in the Annals of Tourism Research used the shutdown of tourism in Hawai‘i during the COVID-19 pandemic to shed light on the relationship between tourism and water use on O‘ahu. The importance of water management is accentuated when there is near […]
Read MorePublication: Tourism water use during the COVID-19 shutdown: A natural experiment in Hawai‘i
Abstract: Many popular tourist destinations are on small islands whose resources are in limited supply, and the effects of climate change and burgeoning tourism tend to worsen the outlook. In this study, we identify the relationship between tourism and water use on the Hawaiian island of O‘ahu. Hawai‘i closed almost entirely to tourism during the […]
Read MoreSocial and Cultural values of Groundwater Dependent Ecosystems in Kona
By Veronica Gibson, Leah Bremer, Kimberly Burnett, Nicole Keakaonaaliʻi Lui, and Celia Smith “I think about the anchialine pools and the significance of the anchialine pools and how, if you have anchialine pools in your ahupuaʻa, especially in a place like North Kona, Kekaha Wai ʻOle,… you’re considered very wealthy” ~ anchialine pool resource manager […]

Read MoreRisk to native marine macroalgae from land-use and climate change-related modification to groundwater discharge in Hawai’i
Dr. Henrietta Dulai in collaboration with UHERO and the Department of Life Sciences, sheds light on the links between submarine groundwater discharge and the health of coastal ecosystems. See press on Hawaiʻi Public Radio and UH News.
Read MoreTraditional and novel time-series approaches reveal submarine groundwater discharge dynamics under baseline and extreme event conditions
UHERO’s Peter Fuleky and his team conducted time-series data analysis and machine learning on a long-term, high resolution radon time-series from Kīholo Bay, Hawaiʻi to analyze the dependencies between rainfall, groundwater and ocean-water levels, coastal salinity, and submarine groundwater discharge. The analyses presented in this research are the first step in understanding what to expect […]
Read MoreA density-dependent multi-species model to assess groundwater flow and nutrient transport in the coastal Keauhou aquifer, Hawai‘i, USA.
Fresh groundwater is a critical resource supporting coastal ecosystems that rely on low-salinity, nutrient-rich groundwater discharge. This resource, however, is subject to contamination from point- and nonpoint-sources such as on-site sewage disposal systems (OSDS) and urban developments. Thus, the significance of flow and transport processes near the coastline due to density effects and water circulation […]
