Costly stakeholder participation creates inertia in marine ecosystems
Ecosystems often shift abruptly and dramatically between different regimes in response to human or natural disturbances. When ecosystems tip from one regime to another, the suite of available ecosystem benefits changes, impacting the stakeholders who rely on these benefits. These changes often create some groups who stand to incur large losses if an ecosystem returns […]
Read MoreElectric Vehicle Greenhouse Gas Emission Assessment for Hawaii
This study estimates greenhouse gas (GHG) emissions of electric vehicles (EVs) compared to that of other popular and similar cars in Hawaii, by county over an assumption of 150,000 miles driven. The GHG benefits of EVs depend critically on the electricity system from which they derive their power. The analysis shows that EVs statewide are […]
Read MoreAssessing the Costs of Priority HISC Species in Hawaii
Over the past decade, funding for the Hawaii Invasive Species Council (HISC) has ranged from less than $2 million per year in the three years following the recent economic downturn, up to almost $6 million in FY2015. The HISC website provides total award amounts for past projects, but it is difficult to attribute exact dollar […]
Read MoreInforming Water Policy in Hawaii with Transformative Interdisciplinary Research: UHERO’s Role in ʻIke Wai
By Kimberly Burnett and Christopher Wada UHERO’s Project Environment will be leading the economic analysis for a new National Science Foundation project addressing critical gaps in the understanding of Hawaii’s fresh water supply that limit decision making, planning and crisis responses. ‘Ike Wai (from the Hawaiian ‘ike, (knowledge), and wai, (water) spans geophysics, microbiology, cyberinfrastructure, […]
Read MoreCost-Effectiveness of Controlling Invasive Miconia via Herbicide Ballistic Technology
By Kimberly Burnett and Christopher Wada Miconia calvescens is an invasive tree native to South and Central America that grows up to 50 feet with shallow root systems that promote erosion. The trees form thick monotypic stands, shading out native plants and threatening the watershed function of Hawaii’s forests. The quick growing miconia can mature […]
Read MoreFilipino 2040: Environmental Resources, Shocks, and National Well-Being
The contribution of the environmental-resource sector to national well-being is the sum of natural resource depletion and environmental degradation. Inasmuch as existing resource stocks are below efficient levels, better enforcement of existing laws as well as policies that incentivize sustainable use are needed. Similarly, progressive royalty assessment of mineral resources can incentivize exploration without transferring […]
Read MoreSustainable Agriculture Irrigation Management: The Water-Energy-Food Nexus in Pajaro Valley, California
The water-energy-food (WEF) nexus is quickly becoming one of the most critical global environmental challenges of the twenty first century. However, WEF systems are inherently complex; they typically are dynamic and span multiple land or agro-ecosystems at a regional or global scale. Addressing this challenge requires a systems approach to optimal and sustainable resource management […]
Read MoreRecent Trends in Hawaii’s Green Economy: Agriculture, Energy and Natural Resource Management
This report provides an update to the 2012 “Foundations for Hawai‘i’s Green Economy: Economic Trends in Hawai‘i Agriculture, Energy, and Natural Resource Management.” Although economic information has long been collected for many sectors in Hawai‘i, including agriculture and energy, the 2012 project was the first to collect indicators specifically for the natural resource management (NRM) […]
Read MoreMethods of the Water-Energy-Food Nexus
This paper focuses on a collection of methods that can be used to analyze the water-energy-food (WEF) nexus. We classify these methods as qualitative or quantitative for interdisciplinary and transdisciplinary research approaches. The methods for interdisciplinary research approaches can be used to unify a collection of related variables, visualize the research problem, evaluate the issue, […]
