人们普遍承认，大多数农业环境措施的实施无法量化预期的环境效益，从而损害了评估其有效性和效率的可能性。本文的目的是说明如何开发基于农业生态系统的多功能特性的农业环境措施的方法是有用的，以克服在评估预期的环境效益的困难。在以下各节中，介绍了欧洲多功能农业实际模式所依据的主要理论概念。在对目前关于联合生产环境非商品的分析的某些方面提出批评之后，提出了将重点从农业的多功能性转向农业生态系统的理由。最后，由AEMBAC项目开发的方法，农业对当地农业生态系统的能力，履行环境功能的影响评估的基础上，提出解释如何这种重点转移促进评估提供多种环境产品和服务。
It is widely acknowledged that the implementation of the majority of agri-environmental measures (AEMs) does not allow for the quantification of expected environmental benefits, thereby undermining the possibilities to assess both their effectiveness and efficiency. The objective of this paper is to show how an approach to develop agri-environmental measures based on the multifunctional character of agro-ecosystem is useful to overcome the difficulties in assessing expected environmental benefits. In the following sections, the main theoretical concepts underlying the actual European model of multifunctional agriculture are introduced. Following a critique of some aspects of the current analysis of the joint production of environmental non-commodities, the rationale to operate a shift of focus from multifunctionality of agriculture to that of agro-ecosystems is proposed. Finally the methodology developed by the AEMBAC project, based on the assessment of impacts exerted by agriculture on the capacity of local agro-ecosystem to perform environmental functions, is presented to explain how this shift of focus facilitates the assessment of the delivering of multiple environmental goods and services.
