摘要:Social-ecological systems in the Mediterranean Basin are characterised by high biodiversity anda prolonged cultural influence, leading to the co-evolution of these systems. The uniquecharacteristics of Mediterranean social-ecological systems, current pressures leading toa decline in ecosystem services, and the need for coordinated action are recognised by policiespromoting the protection and sustainable use of the region’s heritage. Ecosystem assessmentsprovide valuable information on the capacity of the Mediterranean Basin to ensure the wellbeing of its population. However, most assessments simplify the complexity of these systems,which may lead to inaccurate ecosystem services supply and flow estimations. This paper usesthe Driver-Pressure-State-Impact-Response (DPSIR) model to guide an expert consultation thatidentifies the key characteristics of the Mediterranean social-ecological systems and analyseshow these should be included in ecosystem assessments. Data collection was carriedout through expert consultation with ecosystem services researchers. Multiple sources ofcomplexity were identified, including the relationship between historical human activities,biodiversity spatio-temporal patterns, as well as the seasonal and long-term variability inecosystem services. The importance of incorporating this complexity in ecosystem assessmentsfor evidence-based decision-making is identified, suggesting that there is a need to adaptassessment approaches for the Mediterranean Basin social-ecological systems.
