The Effects of Utility Revenue Decoupling on Electricity Prices
Revenue decoupling (RD) is a regulatory mechanism that allows adjustments of retail electricity rates for the regulated utility to recover its required revenue despite fluctuations in its sales volume. The U.S. utility data in 2000–2019 reveals that RD is associated with about a 4-percentage point higher growth rate of residential electricity prices within the first year after […]
Read MoreProducing valuable information from hydrologic models of nature‐based solutions for water
UHERO’s Leah Bremer and a group of international collaborators shed light on ways that ecosystem service modeling can better support real-world decision making through attention to the type of decision maker and to the salience, legitimacy, and credibility of information generated.

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. […]

Principles from social equity literature can be applied to a cost-sharing framework in the CBD’s new protected area strategy.
Read MoreThe Agricultural Economic Landscape in Hawai‘i and the Potential for Future Economic Viability
By Sarah Rehkamp, Michael J. Roberts, and James M. MacDonald In a recent UHERO policy brief, Reviving Agriculture to Diversify Hawai‘i’s Economy, authors pointed to trends in Hawai‘i agriculture and state policies surrounding agricultural land management (La Croix & Mak, 2021). Hawai‘i’s agricultural history has centered around the pineapple and sugar plantations and these are […]
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 […]
Read MoreAssessing the impact of COVID-19 on global fossil fuel consumption and CO2 emissions
We assess the effect of the COVID-19 pandemic on global fossil fuel consumption and CO2 emissions over the two-year horizon 2020Q1-2021Q4. We apply a global vector autoregressive (GVAR) model, which captures complex spatial-temporal interdependencies across countries associated with the international propagation of economic impact due to the virus spread. The model makes use of a unique quarterly data […]
Read MoreEffects of land cover and watershed protection futures on sustainable groundwater management in a heavily-utilized aquifer in Hawai‘i
Groundwater sustainability initiatives, including sustainable yield and watershed policy protection policies, are growing globally in response to increasing demand for groundwater, coupled with concerns about the effects of climate and land-cover change on groundwater supply. Improved understanding of the impacts of watershed management on groundwater yields and management costs—particularly in the broader context of climate […]
Read MoreSea Level Rise and Home Prices: Evidence from Long Island
Global sea level rise is a known consequence of climate change. As predictions of sea level rise have grown in magnitude and certainty, coastal real estate assets face an increasing climate risk. I use a complete data set of repeated home sales from Long Island in New York State to estimate the appreciation discount caused […]
