As the concept of ecosystem services is being operationalised and implemented in policies, a better guidance on the selection of suitable methods for ecosystem services mapping and assessment is needed to allow more sound, transparent and comparable processes. A vast range of assessments focusing on different sets of ecosystem services at various scales is existing and the applied methods cover different disciplines from ecology to economy and social sciences. This complicates the assessment of single or bundles of ecosystem services across spatio-temporal scales and requires a broad expertise. A tiered approach for ecosystem services assessment allows selecting the appropriate application of a certain method for tackling a specific question at a given scale. In this publication, we illustrate how the EU H2020 project ESMERALDA supported the development of such a tiered approach for assessing ecosystem services. The iterative exchanges between experienced researchers and practitioners in mapping and assessing ecosystem services in various contexts allowed the co-production of an approach to guide the choice of methods. Ultimately, the proposed tiered approach will not only support communication of the ecosystem services concept, but will also reduce the tendency for selecting an unsuitable approach for solving complex problems linked to ecosystem services-based resource management.
