Ethan Addicott joined the University of Exeter in 2022 after completing his doctoral work in environmental economics at the Yale School of the Environment.

Ethan’s research programme focuses on natural capital asset valuation, management, and accounting. He is particularly interested in evaluating nature-based solutions to global change in coastal areas.

His work combines theory with detailed biogeophysical and economic data to better understand changes in natural capital assets. Ethan frequently works with natural scientists and other economists to accelerate progress toward a sustainable future.

Research projects

Understanding the Value of Outdoor Culture and Heritage Capital for Decision Makers - Ethan is a co-investigator on a new and exciting grant from AHRC and DCMS that aims to better incorporate the value of outdoor culture and heritage capital into decisionmaking. The project is led by Dr. Amy Binner and includes an interdisiplinary set of co-investigators from the National Trust and Forestry England, two of the UK’s largest landholders, as well as a range of project partners including the Association of Local Government Archaeological Officers, Chartered Institute for Archaeologists, Historic England, National Trails UK,The Heritage Alliance, Lake District National Park, Natural England and South Downs National Park.  

Future Fish Wars: Chasing Ocean Ecosystem Wealth -  Ethan is part of an interdisciplinary team aiming to develop new economic theory and approaches to measure the economic value of fisheries in the context of climate change and growing geopolitical ocean conflict. This £1.1m project is funded by the US Department of Defense's Minerva Research Initiative.

Mapping estimates of coastal beach natural capital values for the US east coast -  Ethan is currently working to create a repeatable pipeline for assessing ecosystem service flows from natural assets along the US east coast. 

Challenges and opportunities for urban stormwater infrastructure in the face of global change - Ethan and Dr. James Webber (Engineering) are developing a collaborative working group to find interdisciplinary solutions to manage storm overflows
