Several federal agencies are developing guidance and policy on the use of ecosystem service analyses to support their conservation and resource management goals. These agencies include the U.S. Army Corps of Engineers, the Bureau of Land Management, and the U.S. Fish and Wildlife Service, among others. At Argonne, various divisions including the Environmental Science Division (EVS) have conducted environmental impact studies and provided recommendations on mitigating the impacts of energy-related development. Such science-based information has been supporting the continuity of ecosystem services provided by air, land, and water resources, which would otherwise have been compromised or even lost. While understanding the impacts of energy development supports the conservation of ecosystems to some extent, it is crucial to understand how the impacts translate into ecosystem services and how this information could be used to support agency management decisions. As the various agencies develop frameworks for use of ecosystem services analyses, it is important that Argonne builds on earlier work to contribute towards these Ecosystem Services endeavors. In this context, this panel discussion will focus on the rationale, methods, and implications of economic analyses and valuation of ecosystem services in energy decisions. Heidi Hartmann is the Program Manager of the Land Resources & Energy Policy Program in EVS. Ms. Hartmann manages projects on environmental impact analysis. Shruti Mishra joined EVS earlier this year and gained experience in ecosystem services valuation during her graduate studies at Ohio State University, and later while working for the U.S. Geological Survey and the World Bank.
