In spite of the diversity of MFA concepts and their functions, there are basically three main reference points: (1) activities for food production; (2) spaces in which nature, landscape and environment preservation and protection take place; (3) the socio-economic structure that links the above-mentioned activities and spaces. Hence, any assessment of MFA requires a multidisciplinary framework able to integrate these multifunctional activities, spaces and agents. Such a framework is far from being built. Economic valuation is just one piece in this complex puzzle. It is basically a tool to produce information on the relative value of environmental and recreational spatial-based services that may be delivered by multifunctional agriculture.
