Value of Watershed Conservation
Return on investment for watershed protection on Kaua‘i
Native forests provide many societal benefits, including protecting freshwater resources that provide drinking water and sustain culturally, economically, and ecologically valuable springs, streams, and groundwater dependent ecosystems. The objectives of this report are to: (1) model future management scenarios for Kaua‘i’s native forests that are co-developed with The Nature Conservancy (TNC) to quantify the impact […]
Read MoreWatershed Protection Provides Strong Return on Investment on Kaua‘i
By Conrad Newfield, Nathan DeMaagd, Christopher Wada, Kimberly Burnett, and Leah Bremer Read the full report. Kaua‘i’s native forests play a vital role in sustaining the island’s freshwater resources. These biodiverse ecosystems capture rainfall and fog, allowing water to seep into underground aquifers, which serve as the primary source of drinking water. However, the expansion […]
Read MoreScaling biocultural initiatives can support nature, food, and culture from summit to sea
Biocultural nature-based solutions provide many social, cultural, and ecological benefits. Yet, there has been little research on related land-sea societal benefits, hindering our ability to finance and scale these solutions. To help fill this gap, we evaluate the land-sea benefits of scaling biocultural restoration initiatives in Hawaiʻi, including multi-strata agroforestry and high-elevation silvopasture combined with […]

Read MoreLinking climate, forests, and limu: Examining the influence of environmental change on groundwater dependent ecosystems in Kona
By Leah Bremer, Brytne Okuhata, Jade Delevaux, Angela Richards Doná, Celia Smith, Veronica Gibson, Henrietta Dulai, Aly El Kadi, Kosta Stamoulis, Kimberly Burnett, Christopher Wada Summary: Natural hazard resilience and increased groundwater pumping are likely to increase the habitat suitability of an invasive seaweed and decrease the abundance of a native and culturally important limu […]
Read MoreEffects of Multiple Drivers of Environmental Change on Native and Invasive Macroalgae in Nearshore Groundwater Dependent Ecosystems
New UHERO Environment and collaborator publication in Water Resources Research demonstrates the connections between forest management, groundwater pumping, natural hazard resilience and nearshore groundwater dependent ecosystems in Kona, Hawaiʻi. Abstract: Groundwater dependent ecosystems (GDE) are increasingly recognized as critical components of sustainable groundwater management, but are threatened by multiple drivers of environmental change. Despite this […]
Read MoreWhat’s a (Better) Beach Day Worth? Economic Valuation of Changes in Waikīkī Beach Characteristics
Abstract: Whether beach nourishment, an established beach management measure, is justified depends on its benefits and costs. We apply a discrete choice experiment at Waikīkī Beach on Oʻahu with mixed logit and latent class models to evaluate recreationists’ willingness to pay for changes in beach width and water clarity as well as the preferences for […]
Read MoreGroundwater management for people and ecosystems under a changing climate: Insights from the Puʻuloa aquifer
By Leah Bremer, Ahmed Elshall, Christopher Wada, Laura Brewington, Jade Delevaux, Aly El-Kadi, Clifford Voss, and Kimberly Burnett Summary:New research from the University of Hawaiʻi ʻIke Wai project indicates that current legal limits on withdrawals from the Puʻuloa (Pearl Harbor) aquifer, the primary water source for Oʻahu, are not sufficient to protect this important resource. […]
Read MorePriority watershed management areas for groundwater recharge and drinking water protection: a case study from Hawai‘i Island
Worldwide, water utilities and other water users increasingly seek to finance watershed protection and restoration in order to maintain or enhance water quality and quantity important for drinking water supply and other human use. Hydrologic studies which characterize the relative effectiveness of watershed management activities in terms of metrics important to water users are greatly […]
