Over the past quarter century, the worldwide production of vegetables has doubled and the value of global trade in vegetables now exceeds that of cereals. In Asia, vegetable production grew at an annual average rate of 3.4% in the 1980s and early 1990s, from 144 million MT in 1980 to 218 million MT in 1993. In addition the area under vegetable cultivation increased at an annual rate of 2.1%, from 12 million hectares in 1980 to 16.3 million hectares in 1993 with most of the increase coming from China. Tomato, cabbage, onion, hot pepper and eggplant are particularly important in Asia and Sub-Saharan Africa.
Chilies are an important vegetable used both for salad and dried condiments. It is gaining a high status due to its high cost.
