World onion production has increased by at least 25% over the past 10 years with current production being around 44 million tones making it the second most important horticultural crop after tomatoes. Because of their storage characteristics and durability for shipping, onions have always been traded more widely than most vegetables.

Onion consumption is increasing significantly and this is partly because of heavy promotion that links flavor and health.
