Millennium Assessment (MA) 2003 Typology of Ecosystem Goods and Services
RegulatingBenefits obtained from
regulation of ecosystem processes
• climate regulation• disease regulation• flood regulation
ProvisioningGoods produced or
provided by ecosystems
• food • fresh water• fuel wood• genetic resources
CulturalNon-material benefits
from ecosystems• spiritual • recreational • aesthetic• inspirational• educational
SupportingServices necessary for production of other ecosystem services
• Soil formation• Waste Treatment and Nutrient cycling• Primary production
Adapted from Millennium Ecosystem Assessment Ecosystems and Human Well Being (2003)

The economic valuation of ecosystem services represent the tradeoffs that individuals make between alternative conditions of these services.
Cost-Benefit Analyses
“Greening” National Income Accounts
Natural Resource Damage Assessments
Valuation Methods:
Direct Use: Goods traded in the market
Non-Direct Use: Hedonic Pricing, Travel Cost, Replacement Cost
Non-Use: Contingent Valuation
Advantages:

Introduction to the EcoValue ProjectA work in progress at the University of Vermont by:
Treg Christopher, Matthew A. Wilson PhD, Austin Troy PhD, Robert Costanza PhD, Shuang Liu
• Scaling-up individual, “environmental economic” studies
• Modifying these values to account for spatio-temporal, context and scale
• Disseminating information to stakeholders via the web

Steps in the EcoValue Project
Literature review and collection
Processing the literature into the database
MS Access Database
Integrating the literature database with spatial data in a GIS
Delivery of the values for ecosystem services via the internet

Current Issues and Future Directions
• Marginal utility• Spatio-temporal context
• Spatio-temporal scale
• Quality of original studies• Aggregation of economic values• Limited availability of Land Cover
change-detection data
![Page 16: University of Vermont, School of Business Administration, Rubenstein School of Environment and Natural Resources, Gund Institute for Ecological Economics](https://reader035.vdocument.in/reader035/viewer/2022062409/56649ce55503460f949b22fc/html5/thumbnails/16.jpg)
• What was the initial condition and what is the proposed change?
• Water Quality and Recreation
• Spatial context• Topological elements of a cover type such as area,
connectivity, fragmentation, and proportion of the landscape
• Ecosystem Dynamics• Threshold of service
• Non-linear change
Supply-side Issues
![Page 17: University of Vermont, School of Business Administration, Rubenstein School of Environment and Natural Resources, Gund Institute for Ecological Economics](https://reader035.vdocument.in/reader035/viewer/2022062409/56649ce55503460f949b22fc/html5/thumbnails/17.jpg)
• Socio-economic factors• Income
• Demographics
• Ethnicity and other cultural characteristics
• Population
• Substitutability
Demand-side Issues
![Page 18: University of Vermont, School of Business Administration, Rubenstein School of Environment and Natural Resources, Gund Institute for Ecological Economics](https://reader035.vdocument.in/reader035/viewer/2022062409/56649ce55503460f949b22fc/html5/thumbnails/18.jpg)
• Temporal scale– Distribution of the impact of service
– Time lags
• Spatial scale:– Who are the stakeholders? Who are the appropriate
valuers?
• Disjunct between human scales of perception and scales at which services operate or generate impacts
– “Only a fraction of what exists, is perceived and only a fraction of what is perceived is responded to” (Jedrzejczak, 2004)
Scale Issues
