About 28% of Pakistan's land is under cultivation and watered by one of the largest irrigation systems in the world. Wheat, rice, sugar cane and cotton are the main products. Cotton accounts for almost 60% of revenues. Pakistan has some reserves of graphite and limestone, as well as a small oil industry.
The overriding economic problem for the Pakistani economy is inflation which was at 10% in 2011, and its huge foreign debt burden, which is over 90% of GDP and consumes over half of government revenue to meet interest payments. The situation has been made more difficult by the history of poor relations between Pakistan and the international financial community generally. Sanctions were imposed following Pakistani nuclear tests in 1998, coinciding with the fall out from the 1997 financial crisis that engulfed the major economies of Asia.
Yet despite these factors, the regional crisis centred on Afghanistan and Iraq, and domestic political instability, the Pakistani economy has performed steadily in the last few years. GDP per capita is $2400. Growth in 2011 was 2.2%, with unemployment at 15.2%.
