Abstract

Ecosystem services as a concept and guiding principle are enjoying wide popularity and endorsement from high-level policy thinkers to industry as support for sustainability goals continue to grow. However, explicit incorporation of ecosystem services into decision making still lacks practical implementation at more local scales and faces significant regulatory and technical constraints. Risk assessment represents an example of a regulatory process for which guidance exists that makes it challenging to incorporate ecosystem service endpoints. Technical constraints exist in the quantification of the relationships between ecological functions and services and endpoints valued by humans, and the complexity of those interactions with respect to bundling and stacking. In addition, ecosystem services, by their very definition, represent an anthropogenic construct with no inherent ecological value, which, in practical terms, requires a far more inclusionary decision making process explicitly incorporating a greater diversity of stakeholder values. Despite these constraints, it is possible, given a commitment to sustainable decision making, to simplify the process based on strategic outcomes (e.g., identifying desired end-states in general terms). Decision analytic techniques provide a mechanism for evaluating tradeoffs across key ecosystem services valued by stakeholders and to develop criteria drawn from the entire spectrum of stakeholders in evaluating potential alternatives. This article highlights several examples of ways in which ecosystem service endpoints can be incorporated into the decision-making process. Integr Environ Assess Manag 2013; 9: 260–268. © 2013 SETAC
