Citrus production

Citrus fruits are the highest value fruit crop in terms of international trade. There are two main markets for citrus fruit:

Most citrus production is accounted for by oranges, but significant quantities of grapefruits, pomeloes, lemons and limes are also grown.

While the origin of citrus fruits cannot be precisely identified, researchers believe they began to appear in southeast Asia at least 4000BC. From there, they slowly spread to northern Africa, mainly through migration and trade. During the period of the Roman Empire demand by higher-ranking members of society, along with increased trade, allowed the fruits to spread to southern Europe. Citrus fruits spread throughout Europe during the Middle Ages, and were then brought to the Americas by Spanish explorers. Worldwide trade in citrus fruits didn't appear until the 19th century and trade in orange juice developed as late as 1940.

Total production and consumption of citrus fruit has grown strongly since the 1980s. Current annual worldwide citrus production is estimated at over 70 million tons, with more than half of this being oranges. According to the United Nations Conference on Trade and Development (UNCTAD), the rise in citrus production is mainly due to the increase in cultivation areas, improvements in transportation and packaging, rising incomes and consumer preference for healthy foods.

This trend was projected to change from 2000 to 2010 since the high production levels have slowed the rate of new plantings.

Citrus fruits are produced all over the world. According to UNCTAD, in 2004 there were 140 citrus producing countries. Around 70% of the world's total citrus production is grown in the Northern Hemisphere, in particular countries around the Mediterranean and the United States, although Brazil is also one of the largest citrus producers.
