Forest protection provides important cost savings to water utility on Maui
By Leah Bremer Researchers from the University of Hawaiʻi Economic Research Organization and Water Resources Research Center partnered with the Nature Conservancy of Hawaiʻi to evaluate how native forest conservation contributes to local water supplies in a water stressed area in East Maui. They found that by preventing the degradation of native forest, conservation efforts […]
Read MoreSubmarine Groundwater Discharge: Updates on Its Measurement Techniques, Geophysical Drivers, Magnitudes, and Effects
The number of studies concerning Submarine Groundwater Discharge (SGD) grew quickly as we entered the twenty-first century. Many hydrological and oceanographic processes that drive and influence SGD were identified and characterized during this period. These processes included tidal effects on SGD, water and solute fluxes, biogeochemical transformations through the subterranean estuary, and material transport via […]
Read MoreCharacterizing Hawai‘i’s Natural Resources Management Sector
This report provides an update to the 2015 “Recent Trends in Hawai‘i’s Green Economy: Agriculture, Energy, and Natural Resource Management” publication, the second update since our original report in 2012. Hawai‘i’s natural resource management jobs were at least 4,697 in 2018, 33% higher than reported for 2014, which is equivalent to an annual growth rate […]
Read MorePlace-based management can reduce human impacts on coral reefs in a changing climate
Declining natural resources have contributed to a cultural renaissance across the Pacific that seeks to revive customary ridge-to-reef management approaches to protect freshwater and restore abundant coral reef fisheries. We applied a linked land–sea modeling framework based on remote sensing and empirical data, which couples groundwater nutrient export and coral reef models at fine spatial […]
Read MoreRecovery of Lost Nexus Synergy via Payment for Environmental Services in Kumamoto, Japan
The objective of this study is to characterize and quantify the “trans-spatial nexus synergy” benefit of subsidized water ponding in the water-energy-food nexus in Kumamoto, Japan. After years of decreased rice production in upstream areas and associated declines in groundwater levels, the Kumamoto city government implemented a subsidy program whereby farmers in the Shira River […]
Read MoreBiocultural Restoration Workday Draws Community Together to Plant an Agroforest
By Zoe Hastings, Mahealani Botelho, and Leah Bremer 1 “I ola ʽoe, i ola mākou nei.” A community member recites the pule (blessing), “my life is dependent on yours, your life is dependent on mine”, to a native aʽaʽliʽi shrub as she gently tucks them into the ground. The side of the ridge is a […]
Read MoreIdentifying Areas of Cost-effective Watershed Management for Groundwater Recharge Protection on Hawai‘i island
In collaboration with the County of Hawai‘i Department of Water Supply (DWS), we identified three priority management areas on Hawai‘i Island: Kohala, Kona, and Kaʻū. These critical recharge areas were identified by DWS as important recharge areas for four aquifers where current withdrawals are near current or future sustainable yield limits: Mahukona, Waimea, Keauhou, and […]
Read MoreInterpreting Life-History Traits of Miconia (Miconia calvescens) through Management over Space and Time in the East Maui Watershed, Hawaii (USA)
Miconia (Miconia calvescens DC) was introduced to the East Maui Watershed (EMW) a half-century ago with more than 25 years of management recorded. Using a historical spatiotemporal data set, we constructed a dispersal kernel for miconia in the EMW. Seedbank persistence, based on postdated recruitment, displayed an exponential decay projecting extinction beyond 20 years. In […]
Read MoreBiocultural Restoration of Traditional Agriculture: Cultural, Environmental, and Economic Outcomes of Lo‘i Kalo Restoration in He‘eia, O‘ahu
There are growing efforts around the world to restore biocultural systems that produce food while also providing additional cultural and ecological benefits. Yet, there are few examples of integrated assessments of these efforts, impeding understanding of how they can contribute to multi-level sustainability goals. In this study, we collaborated with a community-based non-profit in He‘eia, […]
