Because of Andorra's mountainous character, only about 2% of the land is suitable for crops. However, until the tourism sector in Andorra experienced an upsurge, agriculture had been the mainstay of the economy. Hay, tobacco, and vegetables must be irrigated; cereals, mainly rye and barley, are dry-cropped. Most of the cropped land is devoted to hay production for animal feed. Since there is insufficient sunlight on northward-facing slopes and the lands in shadow are too cold for most crops, some southward-facing fields high in the mountains must be used even though they are a considerable distance from the farmers' homes.
Tobacco, the most distinctive Andorran crop, is grown on the best lands. Andorran tobacco is usually mixed with eastern tobaccos, because of its strong quality. Other farm products include cereals, potatoes, and garden vegetables. Grapes are used mainly for raisins and for the making of anisette. The lack of modern methods on Andorra's family farms is causing the agricultural sector to decrease in importance. Most food is now imported.
