Turkmenistan is a largely desert country with intensive agriculture in irrigated oases and large gas and oil resources. One-half of its irrigated land is planted in cotton; formerly it was the world's 10th-largest producer. Poor harvests in recent years have led to an almost 50% decline in cotton exports. With an authoritarian ex-Communist regime in power and a tribally based social structure, Turkmenistan has taken a cautious approach to economic reform, hoping to use gas and cotton sales to sustain its inefficient economy. Privatization goals remain limited. From 1998-2005, Turkmenistan suffered from the continued lack of adequate export routes for natural gas and from obligations on extensive short-term external debt. At the same time, however, total exports rose by an average of roughly 15% per year from 2003-07, largely because of higher international oil and gas prices. Overall prospects in the near future are discouraging because of widespread internal poverty, a poor educational system, government misuse of oil and gas revenues, and Ashgabat's reluctance to adopt market-oriented reforms. In the past, Turkmenistan's economic statistics were state secrets. The new government has established a State Agency for Statistics, but GDP numbers and other figures are subject to wide margins of error. In particular, the rate of GDP growth is uncertain. Since his election, President BERDIMUHAMEDOW has sought to improve the health and education systems, ordered unification of the country's dual currency exchange rate, begun decreasing state subsidies for gasoline, signed an agreement to build a gas line to China, and created a special tourism zone on the Caspian Sea. All of these moves hint that the new post-NYYAZOW government will work to create a friendlier foreign investment environment. Human Development Index 2008 ranking: 109 out of 177
