Much of the research on ecosystem service values (ESVs) has limited applicability to USDA program benefit analyses, largely because the models/data/results (1) lack spatial breadth and hence cannot be applied in national analyses of USDA programs, and (2) do not link land use changes to the changes in ESs. This article provides an overview of a set of 15 ESVs related to agriculture's impacts on erosion in order to identify (1) weaknesses in methods, data, and assumptions that limit the quality of the ESVs and means of avoiding such weaknesses in future ESV development, and (2) approaches that might improve the reliability and spatial resolution of future ESV estimates.

Valuing the ecosystem services delivered by conservation and stewardship programs is of interest within USDA and across the federal government. Answering these types of questions requires accurate and scientifically sound measures of Ecosystem Service Values (ESVs). While there is a rich literature on valuation of nonmarket goods, it is often difficult to use for the ESVs provided by USDA and other federal agencies. To advance understanding of the use of ESVs in conservation programs, this special issue of ARER presents selected papers from a 2019 workshop entitled “Applications and Potential of Ecosystem Services Valuation within USDA – Advancing the Science.”
