In 1987, agricultural production in OECD countries was around 30 per cent of the world total.2 The United States and the European Community each accounted for one-third of the total value added in agriculture in the OECD in 1985, while Japan's share was the third largest at around 16 per cent (see
Table 4.1). OECD countries accounted for roughly three-fifths of world agricultural exports and two-thirds of imports during the 1970s and 1980s (see Table 4.2). The largest exporter of agricultural products during the 1970s and most of the 1980s was the United States, with an average of around 17 per cent of world agricultural exports. The agricultural exports of the EC rose gradually from 7 per cent of the world total in 1970 to 13 per cent in 1987. Canada, Australia and New Zealand each accounted for between 1 and 4.5 per cent over this period, while Japan's exports never exceeded 0.7 per cent (see Chart 4.4).
