The climate in Syria is dry and hot, and winters are mild. Because of the country's elevation, snowfall does occasionally occur during winter. Petroleum in commercial quantities was first discovered in the northeast in 1956. The most important oil fields are those of Suwaydiyah, Qaratshui, Rumayian, and Tayyem, near Dayr az–Zawr. The fields are a natural extension of the Iraqi fields of Mosul and Kirkuk. Petroleum became Syria's leading natural resource and chief export after 1974. Natural gas was discovered at the field of Jbessa in 1940.
Syria, officially the Syrian Arab Republic, is an Arab country in Southwest Asia, bordering Lebanon and the Mediterranean Sea to the west, Israel to the southwest, Jordan to the south, Iraq to the east, and Turkey to the north. The modern state of Syria was formerly a French mandate and attained independence in 1946, but can trace its roots to the Eblan civilization in the third millennium BC. Its capital city, Damascus, was the seat of the Umayyad Empire and a provincial capital of the Mamluk Empire.
Syria is a middle-income, with an economy based on agriculture, oil, industry, and tourism. However, Syria's economy faces serious problems and challenges and impediments to growth, including: a large and poorly performing public sector; declining rates of oil production; widening non-oil deficit; wide scale corruption; weak financial and capital markets; and high rates of unemployment tied to a high population growth rate.
As a result of an inefficient and corrupt centrally planned economy, Syria has low rates of investment, and low levels of industrial and agricultural productivity. Its GDP growth rate was approximately 2.9% in 2005, according to IMF statistics. The two main pillars of the Syrian economy have been agriculture and oil. Agriculture, for instance, accounts for 25% of GDP and employs 42% of the total labor force.
