The ENARPRI partners agreed in February 2004 to prepare a precise specification for the scenarios that partners would attempt to model in their own national contexts, to examine the impacts of trade-related changes upon the multifunctionality of EU agriculture. This paper outlines a suite of five scenarios covering anticipated domestic (EU) policy under different possible outcomes from the Doha round, broadly based upon the status quo (with mid-term review), full decoupling of domestic support and full decoupling plus reductions in (decoupled) domestic support, with variants in relation to export subsidies and the scale of pillar 2 measures. In all cases it is recognised that national or sub-national models will require an additional level of national or regional specification before they can be run, and that each national team will be required to do this drawing upon their own domestic knowledge and discussion with relevant experts. Each of the models that will be used to undertake these analyses is then briefly reviewed to identify its general approach and the multifunctionality indicators that can be covered. These indicators are then set in the broader context that considers other potential indicators of multifunctionality and their rationales. The paper concludes with some additional commentary about the significant differences, and thus the difficulties, of attempting to undertake this exercise for any of the new member states.
