4. The additional duty levied in accordance with paragraph 1 (a) is maintained only until the end of the year in which it was collected and can only be levied at a level not exceeding one third of the ordinary fee in force in the year in which the measure was taken. The volume of triggers is set according to the following timetable, based on market access opportunities defined as the percentage of imports of corresponding domestic consumption (3) in the previous three years for which data are available: in the run-up to the 1986 GATT Ministerial Conference in Punta del Este, Uruguay, agricultural lobbies in industrialized countries strongly opposed agricultural trade-offs. In this context, the idea of excluding “trade-neutral” production and subsidies from WTO commitments was first proposed in 1987 by the United States and soon replicated by the EU.  By guaranteeing continued support to farmers, it has also neutralized the opposition. In exchange for the integration of agriculture into WTO disciplines and the obligation to reduce trade-distorting subsidies in the future, developed countries could maintain subsidies that result in “no more than minimal trade distortion” in order to achieve different public policy objectives.  5. (a) direct payments under production-limitation programmes are not subject to the obligation: to reduce national aid if: the 2003 CAP reform which decoupled most of the existing direct aid and the sectoral reforms that followed, resulted in the shift of most aid under the amber box and the blue box to the green box (61.6 billion euros in 2016/2017, see table below). Aid under the “amber box” (AMS) has fallen sharply, from EUR 81 billion at the beginning of the period of the agreement to EUR 6.9 billion between 2016 and 2017, even with successive waves of expansion. The European Union thus largely respects the commitments made in Marrakech (72.38 billion euros per year) for the AMS. In addition, the “blue box” reached 4.6 billion euros during the same notification period. (a) aggregated measure of assistance and SSA, the annual level of assistance; In monetary terms, provided for an agricultural product for the benefit of producers of agricultural commodities or for non-specific assistance to agricultural producers in general, with the exception of aid under reduction-free programmes under Schedule 2 of the agreement, i.e.
the agreement has been criticized by civil society groups for reducing customs protection for small farmers, a major source of income in developing countries, while allowing rich countries to continue subsidizing agriculture in their own countries.
