Due to its remote geographic location and extensive coastlines, the State of Hawai‘i is particularly vulnerable to climate change and sea level rise (SLR). While Hawai‘i was among the first states to officially recognize the climate crisis and has played a leading role in combating climate change, Hawai‘i’s lawmakers are… Read More
Perspectives from communities threatened by sea-level riseJune 16, 2022"Amid the growing threat of sea-level rise and coastal erosion of oceanfront communities around the world, University of Hawaiʻi at Mānoa researchers delved deeper into the response for coastal communities on Oʻahu. A recent survey of stakeholders discovered that what most respondents felt was currently important did not always match with what they felt should… Read More
Managing for diverse coastal uses and values under sea level rise: perspectives from O’ahu, HawaiʻiJune 7, 2022Effective and equitable coastal decision-making under sea level rise requires managing for multiple coastal uses and values. A new publication led by UHERO's Environmental Policy and Planning Group analyzes how decision-makers in Hawaiʻi perceive diverse uses and values of beaches and coastlines to be important and how they see recognition of these uses and values ideally shaping… Read More
Managing for diverse coastal uses and values under sea level rise: perspectives from OʻahuJune 7, 2022By Leah Bremer, Makena Coffman, Alisha Summers, Lisa Kelley, and Billy Kinney “That whole experience of bonding, the family, the fresh air, that's so critical. And we've lost a lot of that. As we lose the beaches, we lose that part of our culture, which is Hawaiʻi's culture. Whether it's a barbecue… or spend [ing]… Read More
Does air pollution increase electric vehicle adoption? Evidence from U.S. metropolitan areas, 2011–2018April 15, 2022A publication in the Journal of Environmental Economics and Policy by a team of economists including UHERO’s Coffman, Hayashida, and La Croix shows that changes in local air pollution within U.S. metropolitan areas are associated with changes in consumer purchases of new EVs. The authors find a positive association between PM2.5 pollution and BEV adoption, and a negative… Read More
Private Actions to Combat Climate Change Through Offsetting: The Story of The Coconut TravelerApril 7, 2022By Kimberly Burnett, James Mak and Christopher Wada In late 2021, the United Nations (UN) held its 26th climate change conference (COP26) in Glasgow, Scotland. Among the many agreements that emerged from the conference was a coordinated plan for tourism climate action (Glasgow Declaration) to cut tourism’s global carbon emissions in half over the next… Read More
The Rising Cost of Climate Change on Home ValuesOctober 19, 2021By Justin Tyndall Climate change poses a clear threat to coastal real estate assets. As sea level rises and coastal weather events become more severe, exposed properties will experience recurring damage and some will become uninhabitable. Homebuyers may fail to fully appreciate the threat of sea level rise, causing homes in coastal areas to be… Read More
Sea Level Rise and Home Prices: Evidence from Long IslandMarch 31, 2021Global 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… Read More
How Will Climate Change Affect Water Demand? Evidence from Hawai‘i MicroclimatesJanuary 1, 2021The effect that climate change will have on water resource sustainability is gaining international interest, particularly in regions where stocks are strained due to changing climate and increasing populations. Past studies focus mainly on how water availability will be affected by climate change, with little attention paid to how consumer behavior is likely to react.… Read More

Coastal armoring and sinking property values: the case of seawalls in CaliforniaJune 4, 2020Rising sea levels necessitate careful consideration of different forms of coastal protection but cost-benefit analysis is limited when important non-market social costs have not been measured. Seawalls protect individual properties but can potentially impose negative externalities on neighboring properties via accelerated beach loss. We conduct a hedonic valuation of seawalls in two coastal California counties:… Read More
Place-based management can reduce human impacts on coral reefs in a changing climateApril 25, 2019Declining 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 More
Broad threat to humanity from cumulative climate hazards intensified by greenhouse gas emissionsNovember 19, 2018The ongoing emission of greenhouse gases (GHGs) is triggering changes in many climate hazards that can impact humanity. We found traceable evidence for 467 pathways by which human health, water, food, economy, infrastructure and security have been recently impacted by climate hazards such as warming, heatwaves, precipitation, drought, floods, fires, storms, sea-level rise and changes in natural… Read More

Estimating Cost-Effectiveness of Hawaiian Dry Forest Restoration Using Spatial Changes in Water Yield and Landscape Flammability Under Climate Change October 1, 2017 Resource managers increasingly seek to implement cost-effective watershed restoration plans for multiple ecosystem service benefits. Using locally adapted ecosystem service tools and historical management costs, we quantified spatially explicit management costs and benefits (in terms of groundwater recharge and landscape flammability) to assist a state agency in evaluating cobenefits for a predefined restoration scenario (focused… Read More
