Reducing fire risk and restoring value to fallow agricultural lands

October 23, 2023

This blog was conceived via conversations among UHERO faculty and fellows from diverse backgrounds from environmental economics, ecosystem services, economic diversification, and fire and ecosystems. It is meant to stimulate conversation, research, and action towards pathways to address the critical problem of fire risk from unmanaged grasslands and opportunities to support more generative landscapes. We […]

Sea level rise risk interactions with coastal property values: a case study of O‘ahu, Hawai‘i

September 14, 2023

Abstract: Climate change-induced sea level rise (SLR) will affect a range of coastal assets and prompt difficult decisions about coastal land use across the world. Several recent studies find that current and projected SLR is associated with relatively lower property values. We contribute to this growing body of research with a case study of O‘ahu, […]

Effects 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, climate change 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 importance, […]

Managing retreat for sandy beach areas under sea level rise

July 24, 2023

Abstract: Sea level rise (SLR) is projected to impact approximately one billion people by 2100. For many coastal communities, retreat is the most viable long-term option due to exposure risk under SLR and increased coastal hazards. Our research analyzes the costs of retreating coastal development at an iconic beach in Hawaiʻi that is experiencing severe […]

What’s a (Better) Beach Day Worth? Economic Valuation of Changes in Waikīkī Beach Characteristics

May 24, 2023

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 […]
