S-C9 Measuring Natural Capital to Inform Policy and Management

This symposium will introduce Natural Capital Accounting (NCA) focusing on the UN Statistical Commission’s System of Environmental and Economic Accounts (SEEA) – Experimental Ecosystem Accounts (EEA). Presenters will show how the SEEA–EEA approach is being used to inform policy management and programmatic decisions. Case studies will draw from work addressing the food-energy-water nexus by the World Bank-Wealth Accounting and the Valuation of Ecosystem Services (WB-WAVES) partnership and Conservation International in Africa, Asia, the Americas, and Europe. The symposium will examine the use of various methodological approaches to quantify, map, and value ecosystem service stocks and flows and the development and application of decision-support tools designed to enhance the assessment, valuation, and communication of ecosystem services and their contribution to economies.

Ken Bagstad is a Senior Environmental Specialist seconded to the Wealth Accounting and Valuation of Ecosystem Services (WAVES) program. He is developing and testing ecosystem services models to inform national accounts in Africa and Latin America. Since 2010, Dr. Bagstad has worked with the U.S. Geological Survey (USGS) to account for nature’s value in decision-making by U.S. federal government agencies. He has partnered with other agencies on ecosystem service assessments at sites across the U.S. For the last eight years Ken has also served as a lead modeler for the Artificial Intelligence for Ecosystem Services (ARIES) program, and has led the comparative analysis of ecosystem services using multiple other assessment tools.
