Classifying Ecosystem Services for Economic Valuation: The case of forest water services
AbstractSince the release of the Millennium Ecosystem Approach (MEA), studies valuing ecosystem services have grown in the literature. As a consequence of this growing literature, different interpretations exist on the classification of services as derived from MEA, and several studies have argued that this may not be the most appropriate framework when the aim of the analysis is economic valuation. The present work contributes to this debate by reviewing and comparing these critical views in order to: firstly, to clarify the existing confusion in the terminology and interpretations; and secondly, shed some light into a desirable classification and conceptualization of ecosystem services for valuation. To illustrate this, we present an examination of existing primary valuation studies of water related services provided by tropical forests, that we analyze under the MEA classification framework and compare it with an output-based classification, in which the service is defined in terms of their benefits (outputs) to humans. Our results support the idea that an output-based classification should provide with more accurate values and could contribute avoid certain problems such as double counting and potential underestimation of services values.
