These proceedings are part of an OECD series that explores the nature of multifunctionality in agriculture. In November 2006 an OECD workshop was organised to examine the nature and strength of jointness between agricultural commodity production and non-commodity outputs from the perspective of three areas important to the agricultural sector: rural development, environmental externalities and food security. This workshop also examined whether the relationships among these non-commodity outputs were complementary or competing. Finally, the policy implications that could be derived from the findings of this workshop were also a key element in the discussions and are summarised in the Rapporteur's summary.
