Considerations for understanding water availability in West Maui
This piece intends to highlight some of the inherent tradeoffs that make managing water in West Maui especially challenging. In particular, subtracting current/authorized use from “sustainable yield” as defined by the State Water Code and interpreted by CWRM may not be a reliable way to determine remaining water resources available for use. We hope summarizing […]
Read MoreSocial, economic, and health impacts of the Red Hill fuel spill: preliminary survey results
By Leah Bremer, Tara Sutton, Ruben Juarez, Nicole Siegal, Nathan DeMaagd *University of Hawaiʻi Economic Research Organization (UHERO), Water Resources Research Center (WRRC), Department of Geography and Environment, University of Hawaiʻi at Mānoa. BackgroundOn November 20, 2021 the Red Hill Bulk Fuel Storage Facility leaked approximately 19,000 gallons of jet fuel into the Pearl Harbor […]
Read MoreEmbedding local values in Payments for Ecosystem Services for transformative change
Abstract: The potential for Payments for Ecosystem Services (PES) programs to integrate nature’s diverse values into decision-making, and thereby support broader transformative change, is of increasing research interest. We analyze published reviews and case studies of PES from the IPBES Values Assessment to evaluate 1) how diverse values were (or were not) articulated through PES […]
Read MoreSolving Optimal Groundwater Problems with Excel
Abstract: Welfare maximizing management of coastal groundwater requires a sequence of pumping targets, typically terminating with a constant withdrawal rate in the long run. In contrast, managing according to sustainable yield at best identifies the constant rate of pumping in the long run. We illustrate an accessible solution method, using Excel Solver to find the […]
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 MoreFrontiers in páramo water resources research: A multidisciplinary assessment
Abstract: Interdisciplinary knowledge is necessary to achieve sustainable management of natural resources. However, research is still often developed in an exclusively disciplinary manner, hampering the capacity to holistically address environmental issues. This study focuses on páramo, a group of high-elevation ecosystems situated around ∼3000 to ∼5000 m a.s.l. in the Andes from western Venezuela and […]
Read MoreInvesting 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 […]
