He serves as a strategic adviser to the IUCN’s Green Development Initiative.

John led the World Resources Institute’s Business & Ecosystem Services Project, helping its corporate partners develop strategies, policies and new markets for ecosystem services. In this role he was coauthor of the Corporate Ecosystem Services Review and contributed to The Guide to Corporate Ecosystem Valuation and TEEB for Business and Enterprise.

Dr.  Anthony Dvarskas, Senior Consultant, Natural Capital Accounts, Economics of Ecosystem Services

Great Neck, New York +1 (917) 378-4201

Anthony leads our natural capital accounting work. Anthony is an assistant professor in the School of Marine and Atmospheric Sciences at Stony Brook University where he is researching a range of approaches related to the valuation and systematic characterization of ecosystem services. This includes the development of natural capital accounts for pilot locations on Long Island, New York and evaluation of impacts of Superstorm Sandy and similar weather events on natural capital, ecosystem service flows, and community resilience. Prior to joining Stony Brook University, he held posts at the U.S. National Oceanic and Atmospheric Administration (NOAA), the United Nations Statistics Division’s Environmental-Economic Accounting (SEEA) Unit, and the World Resources Institute (WRI). His work focuses on developing approaches for linking biophysical functions to human behavior and integrating the value of nature into national accounts and environmental decision making.

Anthony developed economic approaches for valuing natural resource impacts from contamination and oil spill events, which supported successful settlement of Natural Resource Damage Assessment cases. He also developed models relating tourism to water quality impacts that have informed those involved in water management decisions in Croatia. Anthony has been closely involved in policy discussions related to the integration of ecosystem services into decision making through development of an accounting framework and the establishment of approaches for more fully assessing the benefits of coastal restoration activities.

Dr. Chris Kennedy, Affiliate, Natural Resource Economics

Washington, DC

Chris serves as Assistant Professor of Environmental and Resource Economics in the Department of Environmental Science and Policy and Faculty Researcher in the Center for Climate Change Communication, both at George Mason University. He has extensive experience in the valuation of coastal ecosystem services and the modeling of coupled natural-human systems, primarily coastal and estuarine fisheries. Chris is currently working on a number of projects, including a NOAA-funded study examining how temperature-driven shifts to fluke populations in the mid-Atlantic are affecting fisheries and a multi-disciplinary examination of how climate change is affecting the relationship between herding and fishing economies in Hovsgol, Mongolia. Additionally, Chris is serving on a synthesis team funded by the Maryland Department of Natural Resources and tasked with evaluating the current state of submerged aquatic vegetation (seagrass) in the Chesapeake Bay, and he has participated in a number of other studies with relevance to the Bay, including an examination of how water diversion affects estuarine productivity, and an investigation of the potential for nutrient credit trading to reduce the cost of urban stormwater management under the EPA’s Chesapeake Bay TMDL.

Chris teaches graduate and undergraduate courses focused on introducing economic concepts of sustainability, cost-benefit analysis, and market-based mechanisms for managing environmental externalities. He received a PhD in economics from the University of Wyoming and a BS in chemical engineering from Clarkson University.

Dr. Steven Saul, Director of Ecology

Miami, FL +1 (786) 423-7625

Steve is a seasoned ecologist, natural resource modeler, and remote sensing expert.  Using ecosystem services frameworks and agent based modeling, Steve has developed fisheries management models and strategies for commercial and subsistence fisheries throughout the Gulf of Mexico, Caribbean and South Pacific that are both economically and environmentally sustainable.  To accomplish this, Steve has worked with both not-for-profit and government agencies including the National Oceanic Atmospheric Administration in the United States, where he developed population dynamics models to assess and provide management advice to regional management bodies.

Steve has also worked closely with industry representatives in both developed and developing countries to ensure that their input, data, and concerns are represented throughout the process of developing scientific assessments and resource management policies.  He has published a number of papers and reports in both peer review journals and for government agencies detailing his findings.
