Integrated Valuation of Ecosystem Services: A Systematic Review of Socio-Biophysical Valuation Research

Integrated Valuation of Ecosystem Services (IVES) has emerged as a pluralistic framework for bringing multiple forms of ecosystem service value into relation for environmental decision-making. Within this literature, socio-biophysical approaches have become especially prominent, most often comparing biophysical estimates of ecosystem service supply with social measures of demand-as-use. However, recent studies increasingly move beyond this supply–demand framing by operationalizing alternative social value constructs. This study conducts a scoping review of this emerging literature following PRISMA-ScR procedures. We identify 18 empirical socio-biophysical studies that compare biophysical supply with social value constructs other than demand-as-use. Across these studies, we identify three recurring constructs: perceived importance, perceived supply and recognition of ecosystem services. We examine how each construct is operationalized and how it is compared with biophysical supply. Our synthesis shows that social construct choice shapes the basis of socio-biophysical comparison, the spatial and analytical strategies available and the governance insights that can be drawn from integrated valuation. Perceived importance is most useful for identifying social priorities and anticipating public reception of management interventions. Perceived supply better supports spatial targeting, hotspot-based planning and comparison with modeled ecological supply. Recognition reveals awareness gaps and under-recognized services that can inform communication, education and participatory planning. By clarifying these construct-specific contributions, this review supports more targeted construct selection in future socio-biophysical IVES research.
