Abstract

Mapping ecosystem services (ES) and their production level is crucial for the sustainable management of ecosystems. Likewise, incorporating expert knowledge is significant and beneficial to ES research. In this paper, we calculate a set of eight multi-temporal ES indicators for continental Portugal, employing a spatial modelling approach into a novel index, the ASEBIO index. This index depicts the overall ES potential based on CORINE Land Cover adopting a multi-criteria evaluation method with weights defined by stakeholders through an Analytical Hierarchy Process (AHP). Here, we provide an innovative perspective on ES research applied in Portugal, over a period of 28 years. The resulting ES potential maps show the trade-offs between data modelling conceptualization and stakeholders’ perceptions in balance with the landscape. We find that the overall ES potential perceived by the stakeholders is 137% higher than the value obtained using a modelling-based approach for 2018. All ES potential values are overestimated by stakeholders, which climate regulation, erosion prevention and pollination have the highest overestimation, and water purification the lowest one. Our findings address key challenges for land-use planning at different scales, suggesting an integrative strategy to combine expert-based opinions and data-based models for effective ES assessments.
