Kenneth J. Bagstad, Ph.D.
Ken Bagstad is a Research Economist working with the USGS’ Geosciences and Environmental Change Science Center in Denver. He uses GIS and modeling to quantify, map, and value ecosystem service flows across the United States and internationally.
Ken co-leads work to develop natural capital accounts in the United States at national and regional scales and use this information to support resource management for federal government agencies. Ken has also co-led the development of content for the Artificial Intelligence for Environment & Sustainability (ARIES) project, which has developed software tools to deliver more timely and accurate information for environmental decision making. Through his work on ARIES, Ken has a long-standing interest in the use of artificial intelligence, particularly semantics and machine reasoning, to make scientific data and models interoperable and reusable by both people and computers.
From 2015-2016 Ken was seconded to the World Bank's Wealth Accounting and Valuation of Ecosystem Services (WAVES) Program as a Senior Environmental Specialist. He coordinated the development of ecosystem accounts and their application to national economic accounts in Colombia, Costa Rica, and Rwanda, and assisted with their development elsewhere. For the last several years he has co-taught an ecosystem services modeling course in Spain, and in 2015 he worked in Japan as a Japan Society for the Promotion of Science research fellow.

Critiques of gross domestic product (GDP) as the economy's primary measuring stick have emanated from the feminist and ecological economics communities for decades (Kubiszewski et al., 2013) and have grown to include mainstream economists (Stiglitz, Sen, and Fitousi, 2009) and national accountants (Coyle, 2015). To the casual observer, such critiques seem to be growing almost as quickly as the numAuthorsKenneth J. Bagstad, Mairi-Jane FoxPiloting urban ecosystem accounting for the United States
In this study, we develop urban ecosystem accounts in the U.S., using the System of Environmental-Economic Accounting Experimental Ecosystem Accounting (SEEA EEA) framework. Most ecosystem accounts focus on regional and national scales, which are appropriate for many ecosystem services. However, ecosystems provide substantial services in cities, improving quality of life and contributing to resiliAuthorsMehdi Heris, Kenneth J. Bagstad, Charles Rhodes, Austin Troy, Ariane Middel, Kristina G. Hopkins, John MatuszakAccounting for land in the United States: Integrating physical land cover, land use, and monetary valuation
Land plays a critical role in both economic and environmental accounting. As an asset, it occupies a unique position at the intersection of the System of National Accounts (SNA), the System of Environmental-Economic Accounting Central Framework (SEEA-CF), and (as a spatial unit) SEEA Experimental Ecosystem Accounting (SEEA-EEA), making land a natural starting point for developing natural capital aAuthorsScott A. Wentland, Zachary H. Ancona, Kenneth J. Bagstad, James W. Boyd, Julie L. Hass, Marina Gindelsky, Jeremy G. MoultonIntegrating physical and economic data into experimental water accounts for the United States: Lessons and opportunities
Water management increasingly involves tradeoffs, making its accounting highly relevant in our interconnected world. Physical and economic data about water in many nations are becoming more widely integrated through application of the System of Environmental-Economic Accounts for Water (SEEA-Water), which enables the tracking of linkages between water and the economy. We present the first nationalAuthorsKenneth J. Bagstad, Zachary H. Ancona, Julie L. Hass, Pierre D. Glynn, Scott Wentland, Michael Vardon, John P. FayLinking land and sea through an ecological-economic model of coral reef recreation
Coastal zones are popular recreational areas that substantially contribute to social welfare. Managers can use information about specific environmental features that people value, and how these might change under different management scenarios, to spatially target actions to areas of high current or potential value. We explored how snorkelers’ experience would be affected by separate and combinedAuthorsKirsten L. L. Oleson, Kenneth J. Bagstad, Carlo Fezzi, Megan Barnes, Mary Donovan, Kim A. Falinski, Kelvin Gorospe, Hla Htun, Joey Lecky, Ferdinando Villa, Tamara WongA rasterized building footprint dataset for the United States
Microsoft released a U.S.-wide vector building dataset in 2018. Although the vector building layers provide relatively accurate geometries, their use in large-extent geospatial analysis comes at a high computational cost. We used High-Performance Computing (HPC) to develop an algorithm that calculates six summary values for each cell in a raster representation of each U.S. state, excluding AlaskaAuthorsMehdi Pourpeikari Heris, Nathan Leon Foks, Kenneth J. Bagstad, Austin Troy, Zachary H. AnconaEconomic, land use, and ecosystem services impacts of Rwanda's Green Growth Strategy: An application of the IEEM+ESM platform
We develop and link the Integrated Economic-Environmental Modeling (IEEM) Platform to ecosystem services modeling (ESM). The IEEM+ESM Platform is an innovative decision-making framework for exploring complex public policy goals and elucidating synergies and trade-offs between alternative policy portfolios. The IEEM+ESM approach is powerful in its ability to shed light on (i) change in land use andAuthorsOnil Banerjee, Kenneth J.

Masozera, Emmanuel Rukundo, Evariste RutebukaMapping perceived social values to support a respondent-defined restoration economy: Case study in southeastern Arizona, USA
Investment in conservation and ecological restoration depends on various socioeconomic factors and the social license for these activities. Our study demonstrates a method for targeting management of ecosystem services based on social values, identified by respondents through a collection of social survey data. We applied the Social Values for Ecosystem Services (SolVES) geographic information sysAuthorsRoy Petrakis, Laura M. Norman, Oliver Lysaght, Benson C. Sherrouse, Darius J. Semmens, Kenneth J.

Ecosystem accounts, as formalized by the System of Environmental-Economic Accounting Experimental Ecosystem Accounts (SEEA EEA), have been compiled in a number of countries, yet there have been few attempts to develop them for the U.S. We explore the potential for U.S. ecosystem accounting by compiling ecosystem extent, condition, and ecosystem services supply and use accounts for a ten-state regAuthorsKatie Warnell, Marc J.

Oleson, Stephen M. Posner, Ferdinando VillaQuantifying interregional flows of multiple ecosystem services – A case study for Germany
Despite a growing number of national-scale ecosystem service (ES) assessments, few studies consider the impacts of ES use and consumption beyond national or regional boundaries. Interregional ES flows – ecosystem services “imported” from and “exported” to other countries – are rarely analyzed and their importance for global sustainability is little known. Here, we provide a first multi-ES quantifiAuthorsJanina Kleeman, Matthias Schröter, Kenneth J. Bagstad, Christian Kuhlicke, Thomas Kastner, Dor Fridman, Catharina J. E.
