Multifunctional agroecosystems are the result of complex adaptive interactions between humans and nature where trade-offs between food production and other ecosystem services are key. Our objective is to explore the social preferences for ecosystem services, and the associated willingness to pay, in three multifunctional agroecosystem in Europe (Mediterranean, Atlantic, Alpine) under alternative agrienvironmental policy scenarios. We use the same methodology (a choice experiment including equivalent attributes and levels) to rank and estimate the economic value of provisioning, regulating, supporting and cultural ecosystem services. We define the scenarios (current situation, abandonment and enhanced management) in biophysical terms to elucidate changing relations between social perception and level of delivery of ecosystem services. We derive some lessons. i) Value of ES: biodiversity and regulating ecosystem services always produce welfare gains; people, however, perceive trade-offs between delivery of agricultural landscapes and quality food products. Nevertheless, preferences are heterogeneous and vary across regions, scenarios and ES. ii) Policymaking: society’s willingness to pay for the delivery of ecosystem service exceeds largely the current level of public support. Moreover, further abandonment and intensification of agriculture is clearly rejected by the public. iii) Methodological: monetary valuation is context dependent and extrapolation of economic values can be misleading.

在各种政策情景中探索社会对多功能农业生态系统服务的偏好

多功能农业生态系统是人与自然之间复杂的适应性相互作用的结果,其中粮食生产与其他生态系统服务之间的权衡是关键。我们的目标是在替代性农业环境政策情景下,探索欧洲的三种多功能农业生态系统(地中海,大西洋,高山)对生态系统服务的社会偏好以及相关的支付意愿。我们使用相同的方法(包括等效属性和级别的选择实验)对提供,调节,支持和文化生态系统服务的经济价值进行排名和估算。我们以生物物理术语来定义情景(当前情况,放弃和加强管理),以阐明社会观念与生态系统服务提供水平之间不断变化的关系。我们得出一些教训。i)ES的价值:生物多样性和调节生态系统服务总能带来福利收益;然而,人们却意识到在农业景观的交付与优质食品之间的权衡。然而,偏好是异类的,并且在地区,情景和ES之间有所不同。ii)决策:社会为提供生态系统服务付费的意愿大大超过了当前的公共支持水平。此外,公众显然拒绝进一步放弃和集约化农业。iii)方法论:货币估值取决于具体情况,对经济价值的推断可能会产生误导。意识到在农业景观的交付与优质食品之间的权衡。然而,偏好是异类的,并且在地区,情景和ES之间有所不同。ii)决策:社会为提供生态系统服务付费的意愿大大超过了当前的公共支持水平。此外,公众显然拒绝进一步放弃和集约化农业。iii)方法论:货币估值取决于具体情况,对经济价值的推断可能会产生误导。意识到在农业景观的交付与优质食品之间的权衡。然而,偏好是异类的,并且在区域,场景和ES之间有所不同。ii)决策:社会为提供生态系统服务付费的意愿大大超过了当前的公共支持水平。此外,公众显然拒绝进一步放弃和集约化农业。iii)方法论:货币估值取决于具体情况,对经济价值的推断可能会产生误导。公众显然拒绝进一步放弃和集约化农业。iii)方法论:货币估值取决于具体情况,对经济价值的推断可能会产生误导。公众显然拒绝进一步放弃和集约化农业。iii)方法论:货币估值取决于具体情况,对经济价值的推断可能会产生误导。
