IntroductioǹMultifunctionality' is a term that has entered into public and academic discourse in recent years. While it can refer to any kind of production process, it has been attached most frequently in recent policy debates to the operations of farming (OECD, 2001, page 8), although earlier uses of the term have been recorded, particularly in relation to forestry (Wilson, 2007). Agriculture has been seen as``inherently multifunctional ... . It has many functions or purposes, thereby potentially producing a wide range of outputs or services'' (Dobbs and Pretty, 2004, page 222). In practice, though, multifunctionality is frequently identified not with agriculture in general but with specific kinds of agriculture or agricultural landscape. For example, multifunctionality is often associated with low-intensity, marginal farming and culturally valued geographic regions. In 1998 the OECD defined multifunctionality in these terms:`B eyond its primary function of supplying food and fibre, agricultural activity can also shape the landscape, provide environmental benefits such as land conservation, the sustainable management of renewable natural resources and the preservation of bio-diversity, and contribute to the socio-economic viability of many rural areas. In many OECD countries, because of this multifunctional character, agriculture plays a particularly important role in the economic life of rural areas.'' (OECD, 1998, paragraph 10; our emphasis). In countries where these functions of agriculture are valued intrinsically, governments have asserted their right to protect the nonproduction qualities of farmed landscapes, which are coproduced by agriculture along with food and fibre.Although it is widely accepted that agricultural production has side effects (or`joint products'), some bad (`negative externalities') and some good (`positive externalities'), the discourse of multifunctionality tends to emphasise the public good (beneficial) aspects of farming in general, or of some approaches to farming and farm management. This interpretation of multifunctionality has become intimately connected with support
