you could take Syria as an example ,Syria has produced cotton since ancient times, and its cultivation increased in importance in the 1950s and 1960s. Until superseded by petroleum in 1974, cotton was Syria's most important industrial and cash crop, and the country's most important foreign exchange earner, accounting for about one-third of Syria's export earnings. In 1976 the country was the tenth largest cotton producer in the world and the fourth largest exporter. Almost all the cotton was grown on irrigated land, largely in the area northeast of Aleppo. Syrian cotton was medium staple, similar to cotton produced in other developing countries but of lower quality than the extra-long staple variety produced in Egypt. The cotton was handpicked, although mechanical pickers were tried in the 1970s in an attempt to hold down rising labor costs. ,Syria enjoyed a record cotton crop of 523,418 tons, and the third highest yield in the world, estimated at 3 tons per hectare. To a large measure, this increase was attributable to the government's raising cotton procurement prices by 44 percent in 1981-82, and by another 20 percent in 1982-83 , domestic consumption of cotton increased in the 1960s and 1970s, the government built several textile mills to gain the value added from exports of fabrics and clothes compared with exports of raw cotton. In the 1980s, cotton exports averaged 120,000 tons, ranging from a low of 72,800 tons to a record of 151,000 tons in 1983. Syria's seed cotton harvest was 462,000 tons in 1985, about 3 percent higher than in 1984. Approximately 110,000 tons of the 1985 harvest were destined for export markets. Major foreign customers in 1985 included the Soviet Union (18,000 tons), Algeria (14,672 tons), Italy (13,813 tons), and Spain (10,655 tons).
