a net exporter of wheat to a net importer. During the civil war which began in 2011, the Syrian government was forced to put out a tender for 100,000 metric tonnes of wheat, one of the few trade products not subject to economic sanctions. Less than 2.7% of Syria's land area is forested, and only a portion of that is commercially useful. Limited forestry activity is centered in the higher elevations of the mountains just inland from the coast, where rainfall is more abundant. Illegal drug trade As of 2022, captagon is Syria's most valuable export product and a key source of income for the Syrian regime. The total value of drug shipments sold by the Syrian regime in 2021 are approximately $5.7 billion. Energy and mineral resources Mining Phosphates are the major minerals exploited in Syria. According to estimates Syria has around 1,700 million tons of phosphate reserves. Production dropped sharply in the early 1990s when world demand and prices fell, but output has since increased to more than 2.4 million tons. Syria produced about 1.9% of the world's phosphate rock output and was the world's ninth ranked producer of phosphate rock in 2009. Other major minerals produced in Syria include cement, gypsum, industrial sand (silica), marble, natural crude asphalt, nitrogen fertilizer, phosphate fertilizer, salt, steel, and volcanic tuff, which generally are not produced for export. Oil and natural gas Syria is a relatively small oil producer, accounting for just 0.5% of global production in 2010. Although Syria is not a major oil exporter by Middle Eastern standards, oil is a major pillar of the economy. According to the International Monetary Fund, oil sales for 2010 were projected to generate $3.2 billion for the Syrian government and account for 25.1% of the state's revenue. According to the 2009 Syria Report of the Oxford Business Group, the oil sector accounted for 23% of government revenues, 20% of exports and 22% of GDP in 2008. Syria exported roughly 150,000 bpd in 2008, and oil accounted for a majority of the country's export income. Electrical generation In 2001 Syria reportedly produced 23.3 billion kilowatt hours (kWh) of electricity and consumed 21.6 billion kWh. As of January 2002, Syria's total installed electric generating capacity was 7.6 gigawatts (GW), with fuel oil and natural gas serving as the primary energy sources and 1.5 GW generated by hydroelectric power. A network totaling 45 GW linking
