The acknowledgment of the multifunctionnality of agriculture (MFA) sets up agricultural extension at the crossroads between territorial issues and sector-based issues. This should result into a better access to extension services for farms who contribute to other functions of agriculture than primary production. But at the same time, in European countries, agricultural extension is facing major changes in its financial support, such as commercialization and privatization of services. The purpose of this paper is to assess the impact of the changes on the internal performance of extensions’ suppliers and on directs effects on clients. In this purpose, the conceptual framework or performance of services had been developed. It had been combined with collection of data (both statistical and empirical) about farmers’ consumption of agricultural extension. This framework was tested in the case of technical extension of cereal production in two regions: Ain (France) and Zeeland (Netherlands). The outcomes of the investigation show 1) that privatization and commercialization of services has a strong impact on the performance of services 2) that these performance frameworks could lead to inequalities of for quantitative and qualitative access to technical extension between farmers.
