Although its contribution to GDP is very small, agriculture still employs a considerable number of Portuguese. Chief crops and production figures for 1998 include vegetables (including tomatoes, 2.2 million metric tons), fruit (including grapes and olives, 1.7 million tons),
root crops (including potatoes, 1.1 million tons), and cereal grains (including corn and wheat, 1.3 million tons). Portugal is traditionally one of the world's leading producers of wine (including the world-renowned Porto and Madeira wines) and olive oil. Livestock in 1998 numbered 1.3 million cattle, 6.3 million sheep, 2.2 million pigs, and 33 million poultry. Fishing is also a major industry. Portuguese farmers and fishers—like their colleagues elsewhere in Europe—rely heavily on EU
subsidies, but their slowness to adopt more productive technology has resulted in a loss of EU market share to competitors from Spain, France, and Italy.
