In the WTO's Doha Round, agriculture is again at center stage, even though it accounts for no more than a small and declining share of world trade. The Agreement on Agriculture concluded in the Uruguay Round was a huge step forward in the GATT's dealings with agriculture. But more needs to be done. In recent years, agricultural support in several developing countries has increased while developed countries have reformed their farm policies and improved market orientation. One specific problem in the Doha Round negotiations on agriculture is the treatment of public stockholding for food security purposes. A possible solution could come through an amendment of the rules for measuring domestic support, by agreeing that procurement prices below prices prevailing on international markets are not considered "administered prices".
